Honey bee mortality can be significantly reduced by ensuring that treatments for the parasitic Varroa mite occur within specific timeframes, a new study reveals.
Hidden ‘Highways’ Connect Brazil’s Rainforests
Forests flanking Brazil’s rivers act as “highways” that have allowed tree species to move between the Amazon and Atlantic rainforests for millions of years, new research shows.
Forest landowner motivation to control invasive species depends on land use, study shows
Many U.S. forests are privately owned, particularly in the Eastern and North Central part of the country. This makes control of invasive plants and pests challenging because efforts must be coordinated across landowners. A new study explores how differences in ownership motivation affects willingness to control, and how economic incentives...
Coal emissions cost India millions in crop damages
New research shows grain yields critical to India's food security are dragged down 10% or more in many parts of the country by nitrogen dioxide pollution from power stations that run on coal. Economic losses from crop damages exceed $800 million per year.
New record for CIGS perovskite tandem solar cells
Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams have now presented a CIGS-perovskite tandem cell that sets a new world record with an efficiency of 24.6%, certified by an independent body.
New study model with clues to anti-aging
Scientists have created genetically-engineered mice that could help accelerate anti-aging research.
Why do plants transport energy so efficiently and quickly?
Photosynthesis -- mainly carried out by plants -- is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further. This happens practically loss-free and extremely quickly. A new study shows that quantum mechanical effects play a key role in this...
How healthy stem cells turn into oral cancer
Researchers have identified the molecular and cellular mechanisms that transform healthy stem cells into oral cancer at the earliest stages of the disease.
New device uses electrically assisted wind to fight fires
Researchers have developed a new portable tool that could improve how firefighters douse fires, making the process more efficient and far less risky.
Half a degree further rise in global warming will triple area of Earth too hot for humans
New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2 degrees Celsuis above preindustrial levels. For those aged over 60, the same 2 degree rise would see more...
