On March 1 and 2, Jupiter and Venus will appear side by side in the night sky in an event called a conjunction, which is visible without a telescope or binoculars.

In the last decade, growing numbers of researchers have studied plastic pollution, one of the world's most pressing environmental hazards. They have made progress but still face challenges, such as the comparability of results, especially with regard to microplastic particles.

Nature Communications, Published online: 01 March 2023; doi:10.1038/s41467-023-36427-x A large proportion of recent Brazilian Amazon deforestation is occurring on untitled public forestlands through land grabbing. This emerging risk demands long-term conservation strategies. Here we propose prioritizing land tenure security, technological improvement, and law enforcement.

After losing his beloved father when he was 10, Ronald Mallett read HG Wells and Einstein. They inspired his eminent career as a theoretical physicist – and his lifelong ambition to build a time machine Prof Ronald Mallett thinks he has cracked time travel. The secret, he says, is in twisting the fabric of space-time with a ring of rotating lasers to make a loop of time that would allow you to tr

Researchers have secured £1m to refine method of scoring potential organs by comparing images Artificial intelligence could help NHS surgeons perform 300 more transplant operations every year, according to British researchers who have designed a new tool to boost the quality of donor organs.

A metabolic pathway used for tail regrowth may be critical for tissue regeneration in some cells, a study suggests.

Try your hand at a sciency brainteaser.

Recording the pH within decaying organs for the first time, researchers come closer to understanding why some soft tissues are more likely to be preserved as fossils than others.

Unlike other fast-growing cells, regenerating tadpole cells fuel growth using the pentose phosphate pathway rather than glycolysis, a study indicates.

The "wound current" has intrigued scientists for more than a century. It could turn out to be the key to healing catastrophic injuries.

Jumping genes are let loose in cancerous cells, with multiple effects on cell health.

Noncoding RNAs and microproteins, once considered genomic noise, are turning out to be critical to the progression of some types of cancer.

Getting it wrong can harm the very creatures that scientists are trying to protect.

The University of Chicago cell biologist is studying how the nutrients available to cancers influence their growth.

One in ten early deaths could be prevented if everyone managed at least half the recommended level of physical activity, say a team. The researchers say that 11 minutes a day (75 minutes a week) of moderate-intensity physical activity — such as a brisk walk — would be sufficient to lower the risk of diseases such as heart disease, stroke and a number of cancers.

Scientists thought a gold-throated hummingbird was a new species. DNA revealed that it's a hybrid of two different species, each with pink throats. The discovery sheds light on how birds produce feather colors and how hummingbirds evolved their dazzling hues.

Centuries-old whaling records show how southern right whales are altering their feeding habits.

Researchers reveal that actual methane emissions from the wastewater treatment sector in the U.S. are nearly double what existing international guidelines would predict.

The extent of sea ice around Antarctica has reached a record low level — for the second Southern Hemisphere summer in a row. This year's low is 405,000 square miles below the 1981 to 2010 average minimum extent of sea ice around Antartica, according to the National Snow and Ice Data Center. That amount of ice loss is equivalent to more than half of the land area of Alaska. As Antarctic sea ice shr

When it comes to a quick draw, few creatures outgun adult snapping shrimp (Alpheus heterochaelis). They stun passing fish and foes with a simple click of a spring-loaded claw, which squirts a high-speed jet that rips through the water, producing a vapor-filled bubble (a cavitation bubble) that then implodes, resulting in a catastrophic shock wave—complete with a sharp popping sound and minute flas

Cats have a reputation for being self-sufficient, especially when compared to their canine counterparts. Little bath time is required, for example, thanks to their overzealous grooming habits.

To realize true Internet of Things in future, compact monolithic integrated micro-supercapacitors (MIMSCs) with high systemic performance along with cell number density will become indispensable for powering miniaturized electronics, but their scalable production is still challenging. Several limitations stand as the barriers in their path.

Eating and being eaten is a normal process in nature. These predator–prey dynamics help to stabilize ecosystems. It ensures that individual species do not become too abundant, controls their populations, and prevents damage caused by overpopulation (e.g. browsing by deer in the forest or damage to crops by caterpillars).

A new study of New Zealand blue whales' vocalizations indicates the whales are present year-round in the South Taranaki Bight and their behavior is influenced by environmental conditions in the region.

Classical robots, such as those used for manufacturing, can lift heavy loads and repeat automated processes precisely. But they are too rigid and bulky for delicate work and interaction with humans. The research field of soft robotics works on the development of robots made of soft, organic materials and flexible technical components. Materials researchers at Kiel University have now developed a n

The nitrogen cycle, one of the most important biochemical cycles in all ecosystems, plays a key role in human survival and development. It describes the interconversion process between elementary nitrogen substances and nitrogen-containing compounds in nature. Undoubtedly, the redox reactions between these nitrogen-containing molecules maintain the balance of the nitrogen cycle. However, over the

Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed.

Seeing the aurora borealis so far south is highly unusual, and was thanks to very clear skies The northern lights are usually most visible near the Earth's magnetic north and south poles, but thanks to clear skies across the UK over the past two nights, the light spectacle has reached as far south as Cornwall and Hertfordshire . Here, readers in Scotland and England share their recent sightings.

A Past Resort Humanity is so desperate for solutions to combat climate change that even methods once touted as speculative science fiction are now being entertained as a plausible way forward. Solar geoengineering, or solar radiation modification (SRM) — the process of cooling the planet by reflecting sunlight, likely by injecting aerosols into the atmosphere — is one such proposal. And now, a gr

One of my favorite childhood summertime memories is being surrounded by fireflies. As the sun set, their shimmering glow would spark up the back yard like delicate fairy lights. The fact that living beings could produce light felt like magic. But it's not magic. It's enzymes. Enzymes are the catalysts of life. They drive every step of our metabolism, power photosynthesis in plants, propel viruses

Eliminating animal milk alone from the diet of adults with eosinophilic esophagitis, or EoE, is as effective at treating the disease as eliminating animal milk plus five other common foods, a clinical trial has found. For people with EoE whose disease remains active after they forgo animal milk, a more restrictive diet may help them achieve remission, according to the researchers.
