Eating avocado as part of your daily diet can help improve gut health, a new study shows. Avocados are a healthy food that is high in dietary fiber and monounsaturated fat. However, it was not clear how avocados impact the microbes in the gastrointestinal system or 'gut.'
British scientists investigating new strain of coronavirus, but downplay concerns
British scientists said Tuesday they are trying to establish whether the rapid spread in southern England of a new variant of the virus that causes COVID-19 is linked to key mutations they have detected in the...

Researchers have, for the first time, used unique DNA markers to provide forensic evidence for alleged poaching cases involving the Indian rhino.
Immune cell that drives breast cancer could be effective target in novel immunotherapies
- ScienceDaily
- 20/12/15 22:49
Researchers have identified a type of immune cells that acts as a major driver of breast cancer growth by preventing the accumulation of a specific protein that induces anti-tumor responses. This new knowledge could be utilized for the development of novel immunotherapeutic approaches to treat the disease.
Evapotranspiration in an arid environment
- ScienceDaily
- 20/12/15 22:49
Evapotranspiration is an important process in the water cycle because it is responsible for 15% of the atmosphere's water vapor. Without that input of water vapor, clouds could not form, and precipitation would never fall. It is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants.

Bermudagrass versus the armyworm: Striving for a better understanding of pest resistance in experimental lines
Tifton, Georgia: A study out of the University of Georgia sought to determine the level of host plant resistance that can be assured by several promising experimental bermudagrass genotypes against potential damages committed by the fall armyworm.
Urban land and aerosols amplify hazardous weather, steer storms toward cities
Urban landscapes and human-made aerosols—particles suspended in the atmosphere—have the potential to not only make gusts stronger and hail larger; they can also start storms sooner and even pull them toward cities, according to new research exploring the impact of urban development on hazardous weather, led by scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory.
Study finds a manly beard may help drive sales
The next time you are considering purchasing a big-ticket item, it might be worth paying attention to the salesperson's facial hair.
Urine diversion shows multiple environmental benefits when used at city scale
Diverting urine away from municipal wastewater treatment plants and recycling the nutrient-rich liquid to make crop fertilizer would result in multiple environmental benefits when used at city scale, according to a new University of Michigan-led study.
Oceanographers have an explanation for the Arctic's puzzling ocean turbulence
Eddies are often seen as the weather of the ocean. Like large-scale circulations in the atmosphere, eddies swirl through the ocean as slow-moving sea cyclones, sweeping up nutrients and heat, and transporting them around the world.
Amazon's plastic waste could encircle globe 500 times, report says
Amazon, America's largest online retailer, is deep in the throes of its largest-ever holiday shopping season, a breakneck sprint to ship billions of items in hundreds of millions of packages.
Extreme political advertising can hurt campaign efforts
Aggressive political messaging can work against candidates by radicalizing supporters and alienating moderates, according to a Dartmouth study.
AI model shows promise to generate faster, more accurate weather forecasts
Today's weather forecasts come from some of the most powerful computers on Earth. The huge machines churn through millions of calculations to solve equations to predict temperature, wind, rainfall and other weather events. A forecast's combined need for speed and accuracy taxes even the most modern computers.

Error correction means California's future wetter winters may never come
California and other areas of the U.S. Southwest may see less future winter precipitation than previously projected by climate models. After probing a persistent error in widely used models, researchers at the Department of Energy's Pacific Northwest National Laboratory estimate that California will likely experience drier winters in the future than projected by some climate models, meaning...
Attitudes about climate change are shifting, even in Texas
Longstanding skepticism among Texans toward the climate movement has shifted, and attitudes in the nation's leading energy-producing state now mirror those in the rest of the United States.
The Guardian view on a Covid Christmas: better safe than sorry | Editorial
Easing of UK restrictions should not go ahead while they risk a third wave of coronavirus Christmas is on hold. The governments of the four nations of the United Kingdom are reviewing the proposed relaxation of their Covid restrictions over the holidays. A common policy had been agreed which allowed up to three households to be able to travel and meet up indoors between 23 and 27 December. Many...
