Climate models used by the UN's IPCC and others to project climate change are not accurately reflecting what the Arctic's future will be, experts say.
Triggering bitter taste receptors could someday treat asthma, COPD
Surprisingly, bitter taste receptors are not only located in the mouth, but also elsewhere in the body, including the airways. Activating those receptors opens up lung passageways, so they're a potential target for treating asthma or chronic obstructive pulmonary disease (COPD). Now, researchers report that they have designed a potent...
Organosulfur content of vegetables quantified
Scientists successfully quantified the total reactive polysulfide content of 22 different types of vegetables, including onions and garlic. They also revealed that reactive polysulfides are not only found in the leek genus (Allium), such as onions and garlic but also in the cruciferous family of vegetables (Brassicaceae), such as broccoli...
Surprising similarities in stone tools of early humans and monkeys
Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of...
Jewel beetles evolve to see new colors by duplicating their genes
Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles' vision.
How to assemble a complete jaw
The skeleton, tendons, and glands of a functional jaw all derive from the same population of stem cells, which arise from a cell population known as neural crest. To discover how these neural crest-derived cells know to make the right type of cell in the right location, researchers focused on...
Rutgers scientists identify substance that may have sparked life on Earth
A team of scientists dedicated to pinpointing the primordial origins of metabolism -- a set of core chemical reactions that first powered life on Earth -- has identified part of a protein that could provide scientists clues to detecting planets on the verge of producing life.
Scientists Call for Global Push to Eliminate Space Debris
Scientists have called for a legally-binding treaty to ensure Earth’s orbit isn’t irreparably harmed by the future expansion of the global space industry.
Returning Solar Panel Production to US Eases Climate Change
Domestic production of solar panels – most of which are now made in Asia – can speed up decarbonization in the U.S. and reduce climate change faster, according to new Cornell Engineering research published March 8 by Nature Communications.
Migratory birds take breaks to boost their immune system
Exercising too much and not getting enough rest is likely bad for your health. A new study shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.
