Birds keep fluffy down feathers between their bodies to survive cold climates

Feathers are a sleek, intricate evolutionary innovation that makes flight possible for birds, but in addition to their stiff, aerodynamic feathers used for flight, birds also keep a layer of soft, fluffy down feathers between their bodies and their outermost feathers to regulate body temperature.

Study reveals the structure of heat shock proteins that could treat Huntington's disease

In Huntington's disease, a faulty protein aggregates in brain cells and eventually kills them. Such protein aggregates could, in principle, be prevented with a heat shock protein.

Study on Arctic shrubs lends new understanding to an enduring ecological puzzle

A 15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at small scales? The answer to this question has important implications for how climate change might shift species' distributions across the globe.

Ocean acidification could be affecting lobsters on a molecular scale

The American lobster, which supports the most valuable fishery in North America, maybe more susceptible to the effects of climate change than previously thought, according to a new study published in Ecology and Evolution.

Juicing technique can influence phytochemical content, antioxidant activity of vegetable juices

With the New Year, many people are making resolutions to eat healthier, by eating more vegetables, for example. But those who don't like the taste or texture of some vegetables might prefer to drink them in a home-squeezed juice.

Global collaboration aims to develop new technologies to produce green ammonia

A new global collaboration to examine new ways of producing green ammonia is to receive DKK 21 million from the EU framework program for research and innovation, Horizon 2020. The project is being headed by engineering researchers from Aarhus University.

New approach to biomaterial production may ease environmental burden of forestry, agriculture

It takes a lot to make a wooden table. Grow a tree, cut it down, transport it, mill it ... you get the point. It's a decades-long process. Luis Fernando Velásquez-García suggests a simpler solution: "If you want a table, then you should just grow a table."

Researchers use heat map data to reverse engineer chromosome models

Genome analysis can provide information on genes and their location on a strand of DNA, but such analysis reveals little about their spatial location in relation to one another within chromosomes -- the highly complex, three-dimensional structures that hold genetic information.

Inhaling wildfire smoke's microbial content can increase risk of infection

Wildfire smoke contains microbes, a fact that's often ignored, but one that may have important health repercussions.

No-meat diet will not solve climate crisis, says environmental scientist

People in industrialized regions like the United States of America or Europe are generally urged to eat less meat and animal-source foods as part of a healthier and lower-emissions diet.

Tepary beans are identified as a prospective forage and cover crop

Agriculture accounts for more than a third of water use in the United States. In drier parts of the country, like the southwestern U.S., that fraction can be much higher. For example, more than 75% of New Mexico's water use is for agriculture.

The Earth is warming faster than evolution, shows study

The world is getting warmer, and life has to adapt to new conditions. But if the warming continues, many species may have trouble keeping up.

Olefins formed by light-driven catalyst can help produce drugs, agrochemicals

Taking a cue from light-sensing bacteria that live close to hot oceanic vents, synthetic chemists from Rice University have identified a mild process to produce useful hydrocarbons, called alkenes, or olefins.

New portable optical sensor can monitor plant stress

The portable device allows rapid detection of nitrogen deficiency - a critical nutrient for plant health. When tested on popular vegetables such as Spinach and Kai-Lan, the device was also able to detect levels of other metabolites; allowing measurement of a wider range of plant stress phenotypes such as drought, heat/cold, saline, and light stress.
