On a windy, rainy Sunday, students from the University of Oregon, University of Washington and Evergreen State College picked up trash at Sunset Beach on Oregon’s northern coast, with help from Environment Oregon.

During the cleanup, it was evident that plastic is everywhere, even on the rugged, remote beaches of Oregon’s north shore. Students found plastic bags, plastic debris, bottle caps, and even kid’s toys covering the sand. The event was an important reminder that nothing we use for a few moments should pollute our environment for a lifetime. Young people and students are going to be inherit the planet in the future and we should be doing all we can to safeguard nature and wild spaces for them.

During the 2025 legislative session, there’s a bill (Senate Bill 551) which if passed will help eliminate some of the pollution generated from single-use plastic. You can read more about the bill and its progress in the legislature here.

Research from the University of Bath, published on No Smoking Day 2025, shows that integrating smoking cessation support into NHS Talking Therapies for depression and anxiety increases quit rates. This is an important step in addressing the high rates of smoking in this population.

Led by Dr. Gemma Taylor at the University of Bath, alongside researchers from several other institutions, the study published in Addiction, also found that adding smoking support to mental health treatment didn’t disrupt therapy. Instead, it offered a practical way to tackle mental and physical health together.

The trial was conducted across four NHS trusts in the Midlands, London and the South-west of England between 2019 and 2021. It tested the practicality of integrating smoking cessation support with cognitive behavioral therapy (CBT) for depression and anxiety.

A total of 135 people were split into two groups:

  • One group received 12 sessions of smoking cessation support as part of their CBT session.
  • The other group had standard CBT and were given information about quitting smoking after treatment.

Researchers followed up at three and six months to measure engagement, satisfaction, smoking habits, and mental health outcomes.

Key findings:

  • Quit rates at six months: At six months, 15% of the combined treatment group had quit smoking entirely—more than two and a half times the quit rate of the control group (6%).
  • Impact of CBT on smoking cessation in depression: A Cochrane review reported an 8.8% quit rate for standard smoking cessation treatments among individuals with depression. Findings from the ESCAPE trial reveal that incorporating cognitive-behavioral therapy (CBT) nearly doubles this rate.

The researchers think this study could open the door to bringing smoking cessation support into more mental health services. Therapists are backing the intervention, saying it is both helpful and easy to use, improving clients’ mental and physical health.

Responding to the promising findings, lead researcher Dr. Gemma Taylor from the Department of Psychology at the University of Bath said, “People with depression and anxiety are twice as likely to smoke and quitting is one of the most powerful ways to improve both physical and mental health.

“This study shows that by addressing smoking alongside mental health treatment, the NHS can offer patients a chance to break free from a deadly cycle, improving their well-being in a way that’s practical, effective and life-changing.”

Hazel Cheeseman, Chief Executive of Action on Smoking and Health (ASH) said, “The NHS is letting down people who both smoke and live with depression and anxiety by addressing these issues in silos. By combining treatment, people will see both their physical and mental health improve with long-term benefits to them and the health care system.

“If Wes Streeting wants to shift the NHS from ‘sickness to prevention,’ it must find smarter ways to improve people’s health. This is a ready-made solution that can be slotted into existing services. We will be calling for follow-up studies to see if outcomes can be replicated and services scaled up for all.”

Mark Rowland, Chair of the Mental Health and Smoking Partnership and Chief Executive of the Mental Health Foundation said, “Quitting smoking not only reduces your risk of cancer and heart disease, it is also one of the best ways to improve your mental health and well-being.

“This study shows that the NHS could be doing much more to support people struggling with their mental health to quit smoking. We hope to see a rapid expansion of this model to help more people break out of the cycle of stress and addiction caused by smoking.”

Tom Ayres, Director of the National Collaborating Center for Mental Health said, “People with mental health conditions are just as motivated to quit smoking as the general population but face greater barriers to doing so.

“This research shows that stop smoking support can be embedded in Talking Therapies programs to help people address their tobacco addiction alongside their mental health. This approach should be scaled up to ensure that people with mental health conditions get the support they need to be smoke-free.

Dr. Gemma Taylor said, “Expanding smoking cessation within NHS mental health services isn’t just a smart choice—it’s a crucial step toward improving patient outcomes and building healthier communities.”

People with depression and anxiety are twice as likely to smoke compared to the general population, with 26% of this group in the UK identified as smoking. NHS Talking Therapies were accessed by 1.2 million people in 2024, meaning this smoking support could reach up to 300,000 people who smoke each year.

Evidence suggests that smoking may be contributing to poor mental health. A recent study by Dr. Taylor shows that stopping smoking improves mental health as much as taking anti-depressants.

This study provides a practical and novel way to address high smoking rates in this population and improve physical health inequalities experienced by people with depression and anxiety.

Spiders are important predatory enemies that control a range of insect pests in the rice ecosystem. m-Aminophenylacetylene (m-A) has been demonstrated to induce maternal care behaviors in Pardosa pseudoannulata, protecting young spiders and promoting population growth. Here the roles of m-A on other reproduction stages were evaluated by injecting m-A into virgin and postreproductive female spiders. When injected into virgin females, m-A can prolong the first pulli-carrying stage of the females after mating and breeding offsprings. In postreproductive females, m-A injection shortened the eggsac-carrying stages, especially in the second and third stages. Transcriptomic analysis showed that differentially expressed genes between the control female and m-A-injected female were enriched in the arachidonic acid (AA) metabolism pathway. Real-time quantitative PCR (qPCR) confirmed the upregulation of cyclooxygenase-II (COX-II), prostaglandin E synthase 2 (PGES2), and prostaglandin E synthase 3 (PGES3) genes involved in PGE2 (prostaglandin E2) synthesis. In a reverse validation experiment, the sequential injection of m-A followed by a COX inhibitor aspirin restored the shortened eggsac-carrying stage to normal level. The findings indicated that m-A enhanced PGs synthesis, leading to a reduced eggsac-carrying stage. The eggsac-carrying stage can be fatal when female spiders encounter their enemies, so the shortening of the stage by m-A would reduce the potential threat. These findings are significant for developing environmentally friendly control strategies.

WASHINGTON — The U.S. Space Force will evaluate commercial alternatives to its bespoke military surveillance satellites in geostationary orbit, a move that could reshape the way the Pentagon monitors space as rivals like China and Russia ramp up their capabilities, a senior official said March 11.

Maj. Gen. Stephen Purdy, the acting acquisition executive for the Space Force, has directed program offices to assess how commercially developed satellites and sensors could either replace or augment the military’s existing fleet of Geosynchronous Space Situational Awareness Program (GSSAP) satellites. 

Speaking at a Washington Space Business Roundtable event , Purdy underscored the urgency of exploring industry-led solutions that could offer faster and more cost-effective capabilities.  

“I’ve asked the team to give me a commercial analysis on what kind of capabilities could we provide, on what timeline and at what cost compared to any existing programs of record,” Purdy said. His directive came this week in the form of an “acquisition decision memorandum,” requiring program offices to consider commercial solutions alongside traditional government-developed systems.  

Balancing cost, speed, capability

The Space Force’s GSSAP satellites, built by Northrop Grumman, operate near geosynchronous orbit (GEO) — approximately 22,000 miles above Earth — where they conduct rendezvous and proximity operations to inspect and monitor satellites. This region is home to some of the military’s most critical assets, including missile warning, communications, and intelligence-gathering satellites.  

Purdy said there is now an opportunity to see if commercial space firms — buoyed by private investment — can deliver viable alternatives, and the Space Force will analyze the potential trade-offs. While commercial systems can be built faster and cheaper, military operators typically would have to agree to trade off some requirements that can’t be fully met with commercial systems, he said.  

The challenge lies in striking the right balance between affordability, rapid deployment, and mission effectiveness, he said. “We have to pull our heads out of the legacy, out of the old way of doing business,” Purdy said, suggesting that the Space Force needs to reconsider whether achieving 100% of its requirements justifies bypassing innovations available in the commercial sector.

He stressed that periodic industry engagement is crucial to staying ahead of technological advancements. “What I tell people is you really have to pay attention and dip your head in the water every six months or so to understand what’s happening,” he added. “Space is happening so fast out in the commercial industry.”  

The Space Systems Command, he said, has already received numerous commercial proposals for a geosynchronous situational awareness capability, following a request for information issued last fall.  

International partners

Beyond commercial options, Purdy pointed to the potential for greater collaboration with international allies that have developed similar technologies.  

“This is a capability that international partners have been clamoring to provide,” he said, noting that U.S. Space Command has expressed interest in unclassified solutions that could expand surveillance capabilities while enhancing cooperation with allies.  

Working with international and commercial partners, Purdy suggested, could help the Space Force achieve its goals without the same level of investment required for entirely bespoke military systems.  

The acquisition directive on space domain awareness satellites is only the beginning. Purdy confirmed that similar acquisition reviews will take place across other Space Force mission areas, ensuring that commercial solutions are considered before committing to traditional development paths.  

“There are now several programs that are slow, traditional, expensive, and there’s a potential that there might be commercial opportunities for each one of those,” he said.  

This shift could have major implications for defense contractors, who may need to adjust their business models to compete with commercial players. The move also places new demands on industry leaders to provide clear, realistic assessments of their technology’s capabilities.  

“We need truth in advertising from industry,” Purdy warned. “We need a good, solid understanding of what the capabilities are, not just marketing pitches. We need real technology understanding.”  

At the same time, he cautioned that the Space Force must be disciplined about its requirements. “We have to watch our appetite control. We have to truly understand the technical environment. We have to be willing to take risks.”

As everyone drifts to sleep, you can take the opportunity to capture the endless wonder of the night sky. 

Check out these tips to get your own shots of the night sky.

Where to take photos of the night sky

Before you start snapping shots, it is key to pick a location that is free of light pollution. Light pollution is human-produced modifications to outdoor light that exceed naturally occurring light levels. Light pollution is primarily created when outdoor light escapes upwards or sideways.

Dark sky zones are certified communities, parks, and protected areas by Dark Sky International around the world that preserve and protect dark sites through responsible lighting policies and public education. Dark sky zones are great places to capture the night sky however, rural areas, away from night glow will work. 

What to Pack 

1. A camera with ISO abilities, the feature that controls the amount of light your camera lets in, and a wide angle lens- don’t forget batteries and a memory card. If you are planning on using your phone, installing a manual camera app such as Slow Shutter Cam or Night Camera, allows you to adjust the ISO, shutter speed and focus to have better control over your photos.                  

2. A sturdy tripod as any movement can alter the shot. 

3. A headlamp with red light capabilities to diminish artificial glow and keep your eyes adjusted to the darkness. 

How to take the photos

  • For night sky photography, use the “daylight” or “auto” setting to ensure that the stars, moon, and other elements remain true in color.
  • Set your aperture as wide as possible (around f/2-f/4) to maximize light-gathering capabilities and get the highest quality image results.
  • Use longer shutter speeds to end up with brighter shots. Start with 10 seconds and increase time. Shutter speeds of upwards of ten minutes may capture star trails which show the rotation of the Earth.
  • Use manual focus and infinity focus when shooting for clearer shots 
  • Add foreground to the shots to add dimension and make the sky pop

Skies can be challenging to capture, so be ready to experiment! The night sky remains essentially unchanged, allowing current and future generations to experience a shared sense of wonder that has been intimately linked to human civilization, traditions, and culture throughout the world. To preserve the natural beauty of the night sky, take measures to reduce light pollution.

Public health advice on the safe consumption of glycerol-containing slush ice drinks, also known as slushees, may need revising, conclude researchers after carrying out a detailed review of the medical notes of 21 children who became acutely unwell shortly after drinking one of these products.

Their findings, published in the journal Archives of Disease in Childhood, show that in each case the child became acutely unwell with a cluster of symptoms soon after drinking a slush ice drink, which the researchers refer to as glycerol intoxication syndrome.

The clinical and biochemical features were similar in all of these children and included reduced consciousness, a sudden sharp drop in blood sugar (hypoglycemia), and a build-up of acid in the blood (metabolic acidosis).

Such symptoms, when they occur together, can indicate poisoning or inherited metabolic disorders, prompting further investigations.

Brightly colored slush ice drinks are designed to appeal to children, note the researchers. While the ingredients vary, most of those available in the UK and Ireland are ‘no-added sugar’ or ‘sugar-free’ products and contain glycerol (E422, also known as glycerin), they add.

Glycerol stops the ice from fully freezing, so maintaining the slush effect in the absence of a high sugar content, they explain.

With a view to informing public health policy and guidance for parents, the researchers scrutinized the medical notes of 21 children who had become acutely unwell after consuming a slush ice drink and had initially been diagnosed with hypoglycemia after their arrival in emergency care.

Apart from one child referred in 2009, all the others were referred for further review between 2018 and 2024.

Diagnosis was informed by lab test confirmation of at least two of the following: hypoglycemia; metabolic acidosis; glyceroluria (high levels of glycerol in the urine), and backed up by negative biochemical, enzyme, and/or genetic test results for underlying inherited metabolic disorders.

Information on sex was available for 18 of the children, just over half of whom (10; 56%) were male. Their average age was 3.5, but ranged from 2 to nearly 7.

How quickly they became ill was known for 15: in 14 (93%) this was within 60 minutes. Similarly, the state of consciousness was known for 17, and in 16 this was significantly and suddenly reduced. One child had a seizure. Urgent neuroimaging was carried out in four (33%) out of 12 children.

Twenty children had documented hypoglycemia (blood glucose 2.6 mmol/l or below); but in 13 (65%) this was even lower, indicating severe hypoglycemia. Metabolic acidosis was present in 16 of the 17 children for whom this information was available.

Twelve of 16 children had low levels of potassium, and eight out of nine in whom this was measured had falsely high blood fat levels (pseudohypertriglycerideremia). The researchers concluded that the children had glycerol intoxication syndrome.

All the children recovered quickly after initial resuscitation and stabilization of their blood glucose. They were discharged with advice to avoid slush ice drinks. Twenty did so and had no further episodes of hypoglycemia.

But one drank another slush ice drink at the age of 7 and developed symptoms within an hour, rapidly progressing to vomiting and drowsiness. The parents gave the child a glucose drink, and called an ambulance. When the paramedics arrived, the child’s blood glucose was back to normal and symptoms were already resolving.

Most of the cases in the series presented for emergency care between 2018 and 2024. And the researchers suggest, “A cause of the recent apparent surge in cases may be the reduced sugar content of these drinks, secondary to two main factors: first, public health and parental concerns about high sugar ingestion, and second, the introduction of a ‘sugar tax’ on high sugar (>5%)-containing drinks in Ireland and the UK in 2018 and 2019, respectively.”

These drinks, sold in countries where there’s no sugar tax, contain a much higher glucose content and often don’t contain any glycerol at all, they add.

Based on some of the cases in this series, the UK Food Standards Agency recommended that young children (4 and under) shouldn’t be given slush ice drinks containing glycerol, and that those aged 10 or younger should not have more than one.The Food Safety Authority of Ireland (FSAI) followed suit with similar guidance in 2024.

But the researchers believe that these recommendations may no longer be enough.

“There is poor transparency around slush ice drink glycerol concentration; estimating a safe dose is therefore not easy. It is also likely that speed and dose of ingestion, along with other aspects, such as whether the drink is consumed alongside a meal or during a fasting state, or consumed after high-intensity exercise, may be contributing factors,” they write.

“Food Standards Scotland and the FSAI suggested that 125 mg/kg of body weight per hour is the lowest dose that is associated with negative health effects. For a toddler, this may equate to 50–220 ml of a slush ice drink. The standard size drink sold in the UK and Ireland is 500 ml,” they point out.

Given that these drinks don’t confer any nutritional or health benefits, “recommendations on their safe consumption therefore need to be weighted towards safety,” they suggest.

And they conclude, “To ensure safe population-level recommendations can be easily interpreted at the individual parental level, and given the variability across an age cohort of weight, we suggest that recommendations should be based on weight rather than age. Alternatively, the recommended age threshold may need to be higher (8 years), to ensure the dose per weight would not be exceeded, given normal population variation in weight.”

Microplastics — defined as plastic particles under 0.2 inches – have been discovered most recently in human lungs and brains, as well as in our livers, kidneys, and testes. They have so far been associated with some cancers, respiratory diseases, and pregnancy and birth complications.

Now researchers are adding another ill effect to the persistent particles — boosting antibiotic resistance, according to a study recently published in the journal Applied and Environmental Microbiology.

Antibiotic Resistance Concerns

Laboratory experiments conducted by a team of Boston University researchers demonstrated that bacteria exposed to microplastics became resistant to multiple types of antibiotics. Antibiotic resistance — most often associated with over-prescription and unnecessary use of antibiotics — has been a public health concern for decades.

Adding another means that could make these drugs less effective is concerning, according to the authors — especially for people in dense, impoverished areas, where discarded plastic often accumulates.

“The fact that there are microplastics all around us, and even more so in impoverished places where sanitation may be limited, is a striking part of this observation,” Muhammad Zaman, a Boston University College of Engineering professor and co-author of the paper, said in a press release. “There is certainly a concern that this could present a higher risk in communities that are disadvantaged.”

How Microplastics Lead to Antibiotic Resistance

The authors experimented with multiple kinds of plastics as well as a variety of antibiotics. Each time they came up with the same results: bugs that survived. When bacteria attach to a surface they create a biofilm — a sticky substance that acts as a protective shield.

Although bacteria can grow this film on any surface, the authors say that the effect was “supercharged” on microplastics. They found the rate of antibiotic resistance so high on microplastics versus other materials that they repeated their experiments multiple times. The results remained the same.

“We’re demonstrating that the presence of plastics is doing a whole lot more than just providing a surface for the bacteria to stick — they are actually leading to the development of resistant organisms,” Zaman said.

Direct Links to Human Health

According to the United Nations Environmental Program, research on over 13,000 chemicals used in plastic manufacturing has shown that at least 3,200 may be hazardous to human health.

Although scientists keep finding microplastics in more places and associating them with a longer list of potentially bad health effects, so far most of the research has been in the laboratory. For instance, another study has shown that microplastics can damage human cells.

The next step — whether scientists are looking at their impact from diseases ranging from cancer to infections — will be to study exactly how microplastics directly affect human health.

Earth’s largest iceberg has run aground off the coast of South Georgia Island, a common rendezvous spot for large icebergs, new satellite images show.

Measuring 1,240 square miles (3,460 square kilometers), the Antarctic iceberg A-23A has come to a grinding halt after a long and winding journey across the Scotia Sea, also known as “iceberg alley.”

Satellite images taken at the beginning of March show the iceberg parked on a shallow underwater shelf off the coast of South Georgia Island, which is a British overseas territory in the South Atlantic Ocean and the largest of nine islands that make up the South Georgia and South Sandwich Islands.

The new images of A-23A were taken by the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Aqua satellite. Earlier observations suggest the iceberg’s northward drift slowed suddenly in late February, according to a statement from NASA’s Earth Observatory.

The bill, HB 1052, prohibits the government seizure of land for C02 pipelines. This leaves the fate of Summit Carbon Solutions’ $9 billion, 2,500-mile pipeline project potentially hanging in the air, as South Dakota was a key player in the plan.

Summit’s pipeline was to transport captured C02 from five Midwest states to an underground storage spot in South Dakota, which has been referred to as the world’s largest carbon capture project.

“South Dakota landowners feel strongly that the threat of involuntary easements for the proposed carbon dioxide pipeline infringes on their freedoms and their property rights,” Rhoden wrote in a letter to the legislature and to the people of South Dakota.

“I have said many times that Summit needs to earn back the trust of South Dakota landowners. Unfortunately, once trust is lost, it is a difficult thing to regain.”

“Here is my open message to Summit Carbon or anyone else who wants to try to come abuse our fellow South Dakotans,” Republican South Dakota House Speaker Jon Hansen wrote on X.

“Your green new deal boondoggle; your lawsuits; your threats; and your intimidation against our people, our counties, and our grassroots commissioners ARE NOT WELCOME HERE.”

Summit spokesperson Sabrina Zenor said in a statement that “it’s very unfortunate that, despite our approvals in Iowa, North Dakota, and Minnesota, South Dakota changed the rules in the middle of the game.”

“The governor has made it clear that HB 1052 targets one company – Summit Carbon Solutions,” Zenor continued. “It’s unfortunate that a piece of legislation has been framed around a single company rather than addressing broader infrastructure and economic policy.”

“This is definitely a win for the little guy,” Steve Milloy, a Senior Legal Fellow at the Energy & Environment Legal Institute, told the DCNF.

“Carbon capture is economically, politically, and physically impossible.” He said, referring to carbon capture as “totally bogus” and that “the only reason it’s happening is because oil companies can get taxpayer subsidies for it.”

On March 11 2020, as COVID continued to spread rapidly around the globe, the World Health Organization (WHO) officially declared a pandemic.

More than 7 million people have since died from COVID. The virus, and the public health measures enacted to control it, have had far-reaching effects on societies around the world.


Five years on, the virus continues to circulate. But, thanks to vaccines and immunity acquired from infections, hospitalisations and deaths due to COVID are vastly less frequent than in previous years.


Meanwhile, long COVID continues to have a major impact on people’s lives. Estimates suggest more than 400 million people around the world have had or are currently living with long COVID.


At this point, Australia and the world must take the lessons of COVID – in areas from surveillance, to outbreak response, to vaccines and therapeutics – to be better prepared for the next pandemic.


Some areas we went right – and wrong

Our diagnostic laboratories across Australia were well prepared. Laboratories at the Doherty Institute diagnosed the first case of COVID in Australia and were the first to isolate and share the virus globally in early 2020.


At the same time, a national public health response was quickly put in place. This involved measures such as closing borders, setting up testing centres, and limiting gatherings.


But there are several areas where we could have mobilised more effectively.


During the early stages of the pandemic, there were, at times, challenges with sharing data as well as biological samples and the ingredients for COVID tests between the different states and territories.


For example, there are currently restrictions in place that limit sharing of virus strains between states and territories. But when a new strain emerges, many laboratories need access to it to evaluate their testing capabilities.


One recommendation from an independent 2024 review of the federal government’s COVID response was an Australian Centre for Disease Control. An interim version was launched in early 2024 and the Australian government is investing A$251.7 million in this important initiative.


The goal for the new centre for disease control will be to provide independent technical advice on infectious diseases to government. It will also facilitate rapid integration of data from all states and territories leading to a more unified response.

At the start of a pandemic, we need to understand everything about the new virus and at great speed. This needs systems in place in “peace time”, ready to be mobilised in “war time”.


Back in 2020, we had protocols ready for hospitalised patients and intensive care units to collect specimens and also start new clinical trials. But we were not prepared on many other fronts, for example to collect samples or study how COVID was transmitted in the community or in different key groups.


Every day counts at the start of a pandemic.


Harnessing medical technologies

Relatively recent technological advances in both diagnostics ( RAT tests) and vaccine development (the use of messenger RNA, which gives our body genetic instructions to fight COVID) have put us in a strong position to be at the cutting edge in any pandemic response.


Moderna, one of the two companies that pioneered the mRNA vaccines, has established its Asia-Pacific headquarters in Melbourne. CSL, which made the AstraZeneca COVID vaccines in Australia and manufactures several other vaccines, has now incorporated mRNA in its repertoire.


This capability means Australians could have immediate access to mRNA vaccines in the event of another pandemic. We could also potentially manufacture these vaccines for low- and middle-income countries in our region.


But what if we can’t make an effective vaccine to fight a future pandemic? This is a situation we must be prepared for, as we’ve seen with infections such as HIV, where after 40 years of trying and billions of dollars spent, we still don’t have a vaccine.


In such a situation, we will need to rely on antiviral drugs. The way we currently make antiviral drugs takes significantly longer to develop than vaccines. And although we have some broad spectrum antiviral drugs, the most potent antivirals are very specific – meaning one drug treats only one type of virus.


To be better prepared for future pandemics, many groups around the world are working on developing a library of drugs that work against whole families of viruses that could cause the next pandemic.


Another approach is to develop totally new technologies that are fully tested for one virus, but can be easily adapted to a new virus. This approach could allow more rapid deployment, as the details of safety and dosing would already be understood.


This is one of the major goals of the recently launched Cumming Global Centre for Pandemic Therapeutics based at the Doherty Institute.


These ambitious efforts will require global collaboration, sharing resources and engagement of the private sector.

Once we have a vaccine or drug that works, we need agreed systems in place to ensure widespread equitable access. We fell seriously short of this goal with COVID.


Some low- and middle-income countries received vaccines months or years later than high income countries. For treatments, antivirals such as Paxlovid were never available in many countries.


This is one goal of an agreement led by the WHO, called the “pandemic accord“, to have member states agree on pandemic prevention, preparedness and response. But after years of discussion, there remains no binding agreement.


Preparing for the next pandemic

As COVID was (partly due to advances in technology) the most intensively studied pandemic in human history, we have a unique resource in the record of what happened to inform our response to any future pandemic.


And this is likely a matter of when, not if. New infectious disease outbreaks have continued to emerge over the past five years, including mpox, which was declared a public health emergency of international concern in July 2022 and again in August 2024.


Right now, there’s an outbreak of a new viral disease in the Congo, the origins of which have still not been identified.


We know bats, thought to be the source of the coronavirus behind the COVID pandemic, carry an enormous spectrum of viruses that potentially threaten us. But new pandemics can also arise through mosquitoes and close contact with other animals.


Pandemics are global, not national, problems. We are at a pivotal time where countries including Australia must step up their commitments to this global effort. This will need politicians to rely on the evidence and lessons learned from COVID as well as private and public investment.

Unfortunately, five years down the track, we still have a long way to go to be prepared for the next pandemic.The Conversation
