China will need more than three times as much milk by 2050 as it produced in 2010 and, without changes to its current supply lines, the demand will lift global greenhouse gas emissions from dairy herds by 35%, expand dairy land by 32% and increase nitrogen pollution from dairy production by 48%.

"The consequences of sticking to a 'business-as-usual' scenario are unthinkable," says Zhaohai Bai, an associate professor at the Chinese Academy of Sciences and lead author of a paper from a multinational team of environmental scientists published today in Global Change Biology.

Research from the University of Cambridge has revealed that, among schooling fish, groups can have different collective personalities, with some shoals sticking closer together, being better coordinated, and showing clearer leadership than others.

AURORA, Colo. (Feb. 6, 2018) - An association between inflammation biomarkers in both blood plasma and cerebrospinal fluid (CSF) and markers of Alzheimer's disease (AD) associated pathology, has been found by researchers at the University of Colorado Anschutz Medical Campus working with the University of Wisconsin Alzheimer's Disease Research Center and the University of California San Francisco Memory and Aging Center.

Research co-authored by Portland State University finance professor Jing Zhao found that the religious beliefs of the population in counties where hedge funds are headquartered influence the riskiness of hedge fund managers' portfolios.

The findings, published in a recent issue of the Journal of Corporate Finance, found that fund managers in counties where the population was more religious took fewer risks with their investments than those where religious was less of a factor.

Sponges lack a signaling pathway that responds to low intracellular oxygen levels in more complex animals. Do they use a different mechanism for this purpose or did their earliest ancestors evolve at a time when less oxygen was available?

Some people disturbed by the 2016 presidential election have suffered a loss of appetite, trouble sleeping and concentrating, and have become easily annoyed, while others equally disturbed by the election result have not experienced such symptoms of depression. A new study by UCLA psychologists explains the differences between these two groups.

Those who had no symptoms of depression had either strong family support or heightened activity in two key regions of the brain's reward system: the nucleus accumbens and the medial prefrontal cortex.

CORVALLIS, Ore. - Researchers are paving the way toward a new therapeutic approach for gonorrhea by shedding light on the mechanism behind important proteins on the Neisseria gonorrhoeae bacteria's outer membrane.

Future therapies could come in the form of new antibiotics or, even better, a vaccine.

The findings are especially important as Neisseria gonorrhoeae is considered a "superbug" because of its resistance to all classes of antibiotics available for treating infections.

Small birds are more energy-efficient than bats when flying. Researchers previously believed this was due to air resistance created by the bats' ears. However, biologists at Lund University in Sweden have now discovered another reason.

When in their most elevated position, the wings of small birds interact in a completely different way compared to the wings of bats. As the birds flap their wings downwards, they create a single large air vortex ring behind themselves rather than two small ones.

Scientists at British American Tobacco observed changes in just two genes when human airway tissue was exposed to vapour from its tobacco heating product (THP) - glo. This compares to thousands of gene changes observed in tissue exposed to cigarette smoke. The impact on tissue exposed to glo vapour was minimal and more comparable with that of air when tested in laboratory conditions (Figure 1).

These results add to evidence suggesting that glo has the potential to be substantially reduced risk compared to smoking conventional cigarettes.

Rheological and Thermochemical Research Lab is currently engaged in air injection experiments. One of the types of experiments tackles mechanisms of oxidation reactions of aliphatic and aromatic hydrocarbons. During the last several months, the Lab has managed to conduct tests of oxidation of SARA fractions (saturates, aromatics, resins, and asphaltenes). Differential scanning calorimetry, adiabatic calorimetry, and thermogravimetric analysis coupled with Fourier transform infrared spectroscopy have been among the used methods.
