Ocean species are disappearing before scientists can even find them

Species around the world are vanishing at an accelerating pace, driven by climate change, habitat destruction, and invasive species. Many lesser-known groups, including marine worms, are especially at risk, with some facing extinction before scientists have even identified them. To address this gap, researchers from the University of Göttingen, the…

Scientists discover bizarre new states inside tiny magnetic whirlpools

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have identified previously unseen oscillation patterns known as Floquet states inside extremely small magnetic vortices. In contrast to earlier studies that relied on powerful laser pulses to generate these states, the Dresden team found that gentle stimulation using magnetic waves is enough. This discovery…

Scientists stunned as Mars dust storms blast water into space

Today, Mars is known as a cold, dry desert, but its surface tells a very different story. Ancient channels, water-altered minerals, and other geological features show that the planet once had abundant water and a far more dynamic environment. Understanding how this wetter world transformed into the barren landscape we…

The ice protecting Alaska is vanishing faster than expected

Sea ice is remaining attached to Alaska’s northern coastline for shorter periods each year, based on 27 years of data analyzed by scientists at the University of Alaska Fairbanks. This type of ice, known as landfast ice because it stays fixed to the shore rather than drifting with winds and…

This dangerous combo in your body could raise death risk by 83%

This cow uses tools like a primate—and scientists are stunned

In 1982, cartoonist Gary Larson introduced a famous Far Side comic called Cow Tools. The illustration showed a cow proudly standing next to a strange collection of useless objects labeled as tools. The humor relied on a widely accepted idea that cows lack the intelligence to create or use tools.…

Scientists discover “overflow valve” in cells linked to Parkinson’s Disease

Researchers have uncovered how a mysterious ion channel helps cells break down waste, opening new possibilities for treating Parkinson’s disease. Just like sinks and bathtubs have overflow drains to prevent spills, human cells appear to have a similar built-in safeguard. A new study by scientists from Bonn-Rhein-Sieg University of Applied…

What you do in midlife could reveal how long you’ll live

By the time animals reach midlife, their everyday habits can offer clues about how long they are likely to live. This conclusion comes from a new study supported by the Knight Initiative for Brain Resilience at Stanford’s Wu Tsai Neurosciences Institute. Researchers continuously monitored dozens of short-lived fish throughout their…

Scientists find immune cell linked to long COVID fatigue and symptoms

After infection with SARS-CoV-2, up to 10 percent of people in Germany go on to develop Long COVID. Symptoms can include persistent fatigue, difficulty concentrating, breathing problems, and neurological issues, and they may last for months or even years. The condition does not look the same in every patient, making…

Deepfake X-rays are so real even doctors can’t tell the difference

A new study published on March 24 in Radiology, the journal of the Radiological Society of North America (RSNA), shows that both radiologists and multimodal large language models (LLMs) have difficulty telling real X-rays apart from artificial intelligence (AI)-generated “deepfake” images. The findings raise concerns about the risks posed by…

Vivid dreams may be the secret to deeper, more restful sleep

Feeling like you had “a good night’s sleep” depends on more than just how long you slept. It also reflects how deeply and continuously you believe you slept. Scientists still do not fully understand what happens in the brain to create this sense of deep, refreshing rest. A new study…

Scientists found a bug that generates its own heat in freezing cold

Snow flies might seem like ordinary insects, but their survival strategy is anything but typical.
