A new study provides compelling evidence that Canada lynx populations in Interior Alaska experience a 'traveling population wave' affecting their reproduction, movement and survival. This discovery could help wildlife managers make better-informed decisions when managing one of the boreal forest's keystone predators.
Syrian hamsters reveal genetic secret to hibernation
A gene that limits cellular damage could be the key to surviving prolonged cold exposure.
Where flood policy helps most — and where it could do more
A Federal Emergency Management Agency (FEMA) program provides important flood insurance relief, researchers say. But due to its design, it's used more in communities with greater means to protect themselves, while lower-resourced areas benefit less.
Thaumatin: Natural sweetener with anti-inflammatory potential
A new study shows that bitter tasting protein fragments (peptides) are produced in the stomach during the digestion of the natural sweetener thaumatin. In a cellular test system, the peptides are able to stimulate the acid secretion of human stomach cells and influence inflammatory reactions.
Watch water form out of thin air
Palladium, a rare metallic element, can rapidly generate water from hydrogen and oxygen. Researchers witnessed this process at the nanoscale for the first time with an electron microscope. By viewing the process with extreme precision, researchers discovered how to optimize it to generate water at a faster rate. Process could...
Frequent fizzy or fruit drinks and high coffee consumption linked to higher stroke risk
Frequent drinking of fizzy drinks or fruit juice is associated with an increased risk of stroke, according to new findings . The research also found that drinking more than four cups of coffee per day also increases the risk of stroke.
A river is pushing up Mount Everest’s peak
Mount Everest is about 15 to 50 meters taller than it would otherwise be because of uplift caused by a nearby eroding river gorge, and continues to grow because of it.
The Vikings were part of a global network trading in ivory from Greenland
New research shows that the Vikings traveled more than 6,000 kilometers to the Arctic to hunt for walrus. DNA analyses reveal that walrus ivory from Greenland was brought to Europe and probably as far as the Middle East [M1] via extensive trade networks.
Research reveals impact of gut microbiome on hormone levels in mice
Researchers have shown that the balance of bacteria in the gut can influence symptoms of hypopituitarism in mice. They also showed that aspirin was able to improve hormone deficiency symptoms in mice with this condition.
Discovery of 3,775-year-old preserved log supports ‘wood vaulting’ as a climate solution
A new study suggests that an ordinary old log could help refine strategies to tackle climate change. A team of researchers analyzed a 3,775-year-old log and the soil it was excavated from. Their analysis revealed that the log had lost less than 5% carbon dioxide from its original state.
