A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

Research reveals that for C. elegans worms, the presence of dead members of their species has profound behavioral and physiological effects, leading them to more quickly reproduce and shortening their lifespans. Read more ›

Engineers developed a membrane that filters the components of crude oil by their molecular size, an advance that could dramatically reduce the amount of energy needed for crude oil fractionation. Read more ›

Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process. Read more ›

Every year, total allowable catches (TACs) and fishing quotas are set across Europe through a multi-step process -- and yet many fish stocks in EU waters remain overfished. A new analysis reveals that politically agreed-upon catch limits are not sustainable because fish stock sizes are systematically overestimated and quotas regularly exceed scientific advice. In order to promote profitable and sustainable fisheries, the researchers propose establishing an independent institution to determine... Read more ›

A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing evidence of eight instances in which introners have transferred between unrelated species in a process called 'horizontal gene transfer,' the first proven examples of this phenomenon.

Earth's largest gold reserves are not kept inside Fort Knox, the United States Bullion Depository. In fact, they are hidden much deeper in the ground than one would expect. More than 99.999% of Earth's stores of gold and other precious metals lie buried under 3,000 km of solid rock, locked away within the Earth's metallic core and far beyond the reaches of humankind. Now, researchers have found traces of the... Read more ›

New studies reveal that both the public and healthcare providers often overlook social connection as a key factor in physical health, even though loneliness rivals smoking and obesity in health risks. Read more ›

New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent. Read more ›

Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our understanding of how barred spiral galaxies, like our own Milky Way Galaxy, grow and evolve. Read more ›

The puzzling behavior of Titan's atmosphere has been revealed. The team has shown that the thick, hazy atmosphere of Saturn's largest moon doesn't spin in line with its surface, but instead wobbles like a gyroscope, shifting with the seasons. Read more ›

The risk of heavy rainfall and severe flooding increases with climate change. But property owners -- regardless of size -- often underestimate their own responsibility and are unaware of what preventive measures they can take themselves. Read more ›

If you've ever regretted ordering a spicy meal, take note: A new study identifying molecules that suppress the heat of chili peppers hints at the possibility of adapting these compounds into an 'anti-spice' condiment for food that's too fiery to eat. The research helps explain differences in chili pepper pungency, or spiciness, by identifying three compounds in a range of pepper samples that chemical analysis predicted, and study participants on...

From deadly floods in Europe to intensifying tropical cyclones around the world, the climate crisis has made timely and precise forecasting more essential than ever. Yet traditional forecasting methods rely on highly complex numerical models developed over decades, requiring powerful supercomputers and large teams of experts. According to its developers, Aurora offers a powerful and efficient alternative using artificial intelligence. Read more ›

Is artificial intelligence (AI) capable of suggesting appropriate behavior in emotionally charged situations? A team put six generative AIs -- including ChatGPT -- to the test using emotional intelligence (EI) assessments typically designed for humans. The outcome: these AIs outperformed average human performance and were even able to generate new tests in record time. These findings open up new possibilities for AI in education, coaching, and conflict management. Read more ›

Scientists found that neural networks cannot yet forecast 'gray swan' weather events, which might not appear in existing training data but could still happen -- like 200-year floods or massive hurricanes. Read more ›

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses do not require a power source -- and they enable the wearer to perceive multiple infrared wavelengths. Because they're transparent, users can see both infrared and visible light simultaneously, though infrared vision was enhanced when participants had their... Read more ›
