The United Nations on Wednesday agreed to start negotiating a world-first global treaty on plastic pollution in what has been hailed a watershed moment for the planet. Nearly 200 nations at the UN Environment Assembly in Nairobi unanimously agreed to create an intergovernmental committee to negotiate and finalize a legally binding plastics treaty by 2024.

What it will take to make DoD constellations more resilient and achieve space superiority is still being debated, industry executives said. ORLANDO, Fla. — An often-heard complaint about U.S. military satellites is that they’re not resilient — which generally means they don’t have enough protections against modern electronic jammers, advanced lasers and cyber hacks. This
California is a land divided by a 1,287-kilometer-long (800 miles) rupture known as the San Andreas Fault. Running north to south through the state close to several major cities, it has been responsible for some of the US’s most devastating earthquakes. There are regions in the state’s heart that haven’t experienced the fault’s full fury,
We’ve just taken another step closer to time crystals that can be used for practical applications. New experimental work has yielded a room-temperature time crystal in a system that is not isolated from its ambient surroundings. This, the researchers say, paves the way for chip-scale time crystals that can be used in real-world settings, away
Archaeologists may have just uncovered evidence for the oldest known practice of mummification. Human remains interred 8,000 years ago in the Sado Valley in Portugal, during the Mesolithic, appear to have been deliberately treated for mummification prior to burial. This is the first evidence for Mesolithic mummification in Europe. It’s also possibly the oldest in
On March 4, 2022, a lonely, spent rocket booster will smack into the surface of the Moon at nearly 6,000 mph. Once the dust has settled, NASA’s Lunar Reconnaissance Orbiter will move into position to get an up-close view of the smoldering crater and hopefully shed some light on the mysterious physics of planetary impacts.
Insects have been touted as a food of the future, not least because of the sustainability benefits. An excellent protein source, they take up significantly fewer resources to produce when compared to traditional farming. Give your farm of mealworms around 2 kilograms (4.4 pounds) of food and you’ll get a kilogram of edible protein; with beef,
Microsoft had big plans when it purchased Minecraft, the immensely popular open-world ‘sandbox’ game, back in 2014 for US$2.5 billion. Among them was to invest heavily in an educational revolution – the gamification of learning. It’s not hard to imagine how the logic-based mechanics of Minecraft’s construction system could help teach knowledge and practical skills in fields of
SAN FRANCISCO – GPS radio frequency interference can signal impending military activity. HawkEye 360 proved that point in a March 4 news release on GPS interference in and around Ukraine over the last four months. Prior to the Russia’s Feb. 24 invasion of Ukraine, the Herndon, Virginia-based geospatial analytics company noted continual and increasing GPS
Unnerving images of a mummified shark that looks like a zombie, as well as other dead and decaying sea creatures, have been captured in eerie new footage of an abandoned aquarium. The spooky viral video was taken by a pair of “urban explorers” who broke into the unnamed aquarium in Spain. The video was posted
In his theory of general relativity, Einstein predicted something called time dilation: the notion that two clocks under two different gravitational pulls will always tick at different speeds. The effect has been observed in many experiments since, but now scientists have recorded it at the smallest scale seen so far. The result was achieved using ultra-precise
For you to read this article, the eyes have to perform quite the task – light enters the cornea and travels through the pupil and lens to the retina at the back, where light-sensitive cells such as cones and rods then pass things on to the brain via electrical signals in the optic nerve. Now,
A well-studied solar phenomenon may not be quite as simple as we we thought it was. New simulations suggest that what we thought were loops of plasma known as coronal loops erupting out from the surface of the Sun along magnetic field lines may, at least sometimes, be wrinkles in corrugated sheets of plasma. Astronomers
Rising global temperatures bring dire threats, such as floods, heat-related injuries, water scarcity, and hunger, making up to 3.6 billion people – nearly half of the world’s population – highly vulnerable to climate change. That’s according to a major report, released Monday, from the Intergovernmental Panel on Climate Change – a UN body that recruits
There was a time, not so long ago, when computers were so large, they occupied entire rooms. Today, some processing units can come as small as a few specks of dust. Even next to a grain of rice, these stacks of micrometer-sized chips look infinitesimal. Shrinking computer batteries to fit that size, however, has proved more
WASHINGTON — An Atlas 5 successfully launched the latest in a series of geostationary weather satellites March 1, exactly four years after the launch of the satellite it is replacing. A United Launch Alliance Atlas 5 lifted off from Space Launch Complex 41 at Cape Canaveral Space Force Station on schedule at 4:38 p.m. Eastern.
Patagonian ice fields are among some of the fastest-melting glaciers on the planet. As these glaciers disappear, the earth that once lay beneath them is rebounding upwards at rates much faster than expected. Now, scientists have worked out a gap in tectonic plates that began forming some 18 million years ago underneath now-shrinking ice fields
Successfully achieving nuclear fusion holds the promise of delivering a limitless, sustainable source of clean energy, but we can only realize this incredible dream if we can master the complex physics taking place inside the reactor. For decades, scientists have been taking incremental steps towards this goal, but many challenges remain. One of the core
It’s been nearly 80 years since two nuclear bombs were detonated over the Japanese cities of Hiroshima and Nagasaki, killing at least 129,000 people, and causing devastating, long-term health effects. To date, those are the only instances of nuclear weapons being used for warfare, but the reality is there are roughly 12,700 warheads remaining in the
A signal interpreted as the first light illuminating the Universe may not be from the far reaches of the Universe after all, a new study has found. In fact, it may not even be from space. Far from being a problem, however, this new finding may just set the Universe to rights. The signal, described
Nearly 200 nations approved a major UN climate change report detailing the accelerating impacts of global warming on Sunday, at the end of a sometimes fraught two-week meeting overshadowed by Russia’s invasion of Ukraine. The Intergovernmental Panel on Climate Change (IPCC) confirmed that debates had concluded over the report’s crucial “Summary for Policymakers”, a 40-page
The largest plane in the world – Ukraine’s Antonov-225 cargo plane – was destroyed by Russian strikes outside Kyiv on the fourth day of Moscow’s invasion, Ukraine’s state-owned Ukroboronprom group said Sunday. “Russian invaders destroyed the flagship of the Ukrainian aviation, the AN-225” at the Antonov airport in Gostomel near Kyiv, the group said in
HELSINKI — China’s second Long March 8 rocket launched late Saturday carrying a domestic record 22 satellites for a range of commercial Chinese space companies. The Long March 8 lifted off from Wenchang Satellite Launch Center at 10:06 p.m. Eastern Feb. 26, with the China Aerospace Science and Technology Corporation (CASC) later confirming launch success.
We humans are versatile and accomplished navigators, but insects might have navigation skills that are even better. For them, it’s literally a matter of life and death – and that’s why we decided to freeze some ants and beetles (don’t worry, they still survived) to learn more about how they remember their way home after
Scientists would be able to discover much more about what lies underground if our planet could be sliced open and viewed as a cross-section – but as that’s not really possible, they have to rely on a variety of other methods instead. One new approach has just been proven in the field: A recently developed
The capacity to engage with and comprehend music spans nearly every human society. While other creatures also display musical behaviors (think bird song, humpback whale calls, or bonobo vocalizations), our musical cognition appears to be evolutionary distinct within the animal kingdom. A new study has given us more insight into the brain’s relationship with music, finding that singing
Not all planetary systems are alike. Out there in the big, wide galaxy, a number of different configurations have been spotted, some vastly different from our home system. These include extrasolar planets, or exoplanets, that orbit not one, but two stars, like the fictional Star Wars world of Tatooine. Now, for the first time, astronomers have
Fresh water cycles from ocean to air to clouds to rivers and back to the oceans. This constant shuttling can give us the illusion of certainty. Fresh water will always come from the tap. Won’t it? Unfortunately, that’s not guaranteed. Climate change is shifting where the water cycle deposits water on land, with drier areas
We can add suggesting and proving mathematical theorems to the long list of what artificial intelligence is capable of: Mathematicians and AI experts have teamed up to demonstrate how machine learning can open up new avenues to explore in the field. While mathematicians have been using computers to discover patterns for decades, the increasing power
Rather than engineering robotic solutions from scratch, some of our most impressive advances have come from copying what nature has already come up with. New research shows how we can extend that approach to robot ‘minds’, in this case by getting a robot to learn the best route out of a maze all by itself – even
