NASA Satellites Uncover Large-Scale Ocean Nutrient Stress 

As Earth’s oceans warm, microscopic marine organisms are experiencing increasing stress due to a lack of vital nutrients. A new study combining NASA satellite observations, ocean surveys, and genetic testing on marine microorganisms suggests that warming ocean waters are limiting nutrient availability across much of the global ocean, with the potential to reshape marine ecosystems.  The research, published June 5 […]

NASA Satellites Help Map Ocean Nutrient Stress 

Editor’s note: This article was updated on June 5. A new study combining NASA satellite observations, ocean surveys, and genetic testing on marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. The researchers report that this nutrient stress affects microscopic marine organisms and could influence […]

First Steps: America’s Grueling Second Spacewalk

One year after Gemini IV astronaut Edward H. White completed NASA’s first spacewalk the agency prepared for a demanding second excursion. Originally scheduled for Gemini VIII, the extravehicular activity (EVA) was reassigned to Gemini IX-A after that mission ended early, with Gene Cernan taking on the task. On June 5, 1966—the mission’s third day—Cernan exited […]

AI-designed universal coronavirus vaccine passes first human trial

Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS, and related bat viruses with pandemic potential. By targeting features shared across an entire virus family, it aims to provide protection even as viruses evolve.

Scientists discover why ozempic may not work for some people

Scientists have identified genetic variants that may make some people less responsive to GLP-1 drugs used to treat Type 2 diabetes. Roughly 10% of the population carries these variants, which appear to cause a mysterious form of "GLP-1 resistance." In several clinical trials, carriers were significantly less likely to reach healthy blood sugar targets while taking GLP-1 medications.

Octopuses use mirrors to find food they cannot see

Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly identified the food’s location about 73% of the time, showing they could use a mirror as a tool rather than simply reacting to a reflection.

Hidden supermassive black hole pairs may finally have a visible signal

Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes’ gravity. The timing and brightness of these bursts could provide a unique fingerprint of black holes slowly spiraling toward a future collision.

Magnetic fields may be the secret behind binary star formation

Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer simulations show that magnetic fields surrounding newborn stars can act like a cosmic brake, stripping away angular momentum and allowing two still-forming protostars to spiral closer together instead of drifting apart.

Scientists discover a hidden quantum world inside cobalt

Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states enable extremely fast electron behavior and can be switched or controlled using magnetism. The discovery could open new paths toward next-generation computing and spin-based devices.

Rising seas could drown mangroves and release vast stores of carbon

Mangroves are famous for trapping vast amounts of carbon, helping slow climate change. However, a new study suggests rising sea levels could eventually reduce that benefit across entire forests. As flooding becomes too extreme, mangroves may die off and their carbon-rich soils could erode, potentially turning these coastal ecosystems from carbon sinks into carbon sources.

Giant fire tornadoes could clean up oil spills faster with less pollution

Researchers have shown that controlled fire whirls can clean up oil spills faster and more cleanly than traditional burning methods. The spinning flames consumed up to 95% of the oil, cut soot emissions by 40%, and could help prevent spills from reaching sensitive marine habitats.

Scientists are seriously asking if bees and ChatGPT are conscious

New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar. Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects and future machines.

The biggest collagen study yet reveals what actually works

A major review of nearly 8,000 participants found that collagen supplements can improve skin health and ease osteoarthritis symptoms, especially when taken consistently over longer periods. Researchers also found modest benefits for muscle and tendon health. But the results challenge claims that collagen enhances sports performance, as it showed little effect on recovery or post-workout soreness.
