Phys.org / Why doesn't coffee taste like caffeine?
Though decaf fans might disagree, caffeine is a critical component of a cup of joe. This compound is incredibly bitter on its own, but regular coffee itself is not. A team reporting in the Journal of Agricultural and Food ...
Medical Xpress / Senescent cells dodge cell death by rewiring fat metabolism, study shows
In response to stress or damage, cells undergo senescence and stop dividing. However, if senescent cells accumulate in tissues over the long term, chronic inflammation occurs and the risk of cancer increases. Researchers ...
Phys.org / Prescribed burns are lit in Australia's Northern Territory to minimize the severity of fires later in the season
In May and June of most years, NASA satellites typically begin to detect large numbers of wildland fires throughout the Top End and Arnhem Land regions of Australia's Northern Territory. On some days, especially in the afternoon, ...
Phys.org / Lab evolution recreates COVID's path to omicron in months, reveals key conditions
A key step in the origin of many pandemics occurs when an animal-borne virus infects humans and then evolves to spread more efficiently from person to person. That is why scientists and physicians keep a close watch on viruses ...
Phys.org / Image: Colorful, chaotic Jupiter
NASA's Juno spacecraft captured this color-enhanced view of Jupiter's northern hemisphere during its 61st close flyby of the giant planet on May 12, 2024.
Phys.org / Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves
Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there ...
Medical Xpress / Yes, you really can be allergic to exercise—and the symptoms can be serious
People who don't like to workout will sometimes joke that they're "allergic" to exercise. But what many don't realize is that an allergy to exercise is a real thing—and it can be dangerous if not caught in time.
Phys.org / Real-time fish interaction enlarges young guppy brains, while screen time falls short
Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. ...
Phys.org / From forest to front door: Understanding how wildfire spreads through communities
As California's population boomed—from 10 million in 1950 to over 40 million today—the number of people living in fire-prone areas multiplied. Over the decades, millions of new homes and commercial buildings sprang up to ...
Phys.org / Meteor as heavy as an elephant causes widespread speculation across New England
When the double boom rang out in New England over the weekend, shaking homes and sending pets fleeing, questions started flooding social media.
Phys.org / Rising seas could eventually 'drown' mangroves and release carbon
Mangroves could store less carbon—and even begin releasing it—as sea levels rise, suggests new research in Earth's Future. Mangroves are made up of salt-tolerant plants that grow in coastal areas. They cover less than 1% ...
Medical Xpress / Retraining the immune system to treat type 1 diabetes
Type 1 diabetes (T1D) is a lifelong autoimmune disorder where the immune system attacks islets, certain areas of the pancreas, and destroys cells that would otherwise produce insulin, a hormone crucial for regulating blood ...
