Organisms need to work together to adapt to climate change, especially in the presence of competitors, suggests a new study published today in eLife.
The findings show that some species can maximise their fitness in suboptimal environments by working together, highlighting how the pressing issue of habitat destruction affects the vulnerability of social organisms to climate change.

Washington, DC, August 18, 2020 - A new study reports that the risk of being involved in car crashes increases for those diagnosed with attention-deficit/hyperactivity disorder (ADHD).
In an anatomical comparison of the third metacarpal, or cannon bone, among Thoroughbred racehorses, American Quarter Horses and feral Assateague Island ponies, Johns Hopkins Medicine researchers have found that fostering adaptations in these bones through training might help horses better endure the extreme conditions of racing and prevent serious, often life-ending injuries on the track.
Racehorses operate at a biomechanical extreme. The 1,000-pound or so animals can move up to 40 miles per hour on long, thin limbs genetically evolved to move them across long distances.
Many people beat the summer heat by cranking the air conditioning. However, air conditioners guzzle power and spew out millions of tons of carbon dioxide daily. They're also not always good for your health--constant exposure to central A/C can increase risks of recirculating germs and causing breathing problems.
There's a better alternative, say a team of researchers from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre.
They call it the Cold Tube, and they have shown it works.
GALVESTON, Texas - A new study by researchers from The University of Texas Medical Branch at Galveston uncovered new information on why the Ebola virus can live within bats without causing them harm, while the same virus wreaks deadly havoc to people. This study is now available in Cell Reports.
The Ebola virus causes a devastating, often fatal, infectious disease in people. Within the past decade, Ebola has caused two large and difficult to control outbreaks, one of which recently ended in the Democratic Republic of the Congo.
In smaller spacecraft such as CubeSat satellites, a salt-based monopropellant is showing promise. It can be used both in high-thrust chemical propulsion for fast time-sensitive maneuvers, and electric mode for slow maneuvers, such as orbit maintenance. Now, researchers in the Department of Aerospace Engineering at the University of Illinois at Urbana-Champaign have more knowledge about how it performs under pressure.
The propellant, called FAM-110A, is a mixture of two commercially available salts.
WASHINGTON -- Researchers have developed a new instrument that has, for the first time, measured tiny light-evoked deformations in individual rods and cones in a living human eye. The new approach could one day improve detection of retinal diseases such as age-related macular degeneration, a leading cause of blindness in people over 55 worldwide.
Penn State researchers, in a recent study, were surprised to learn that they could take the exact same number of seeds from the same plants, put them in agricultural fields across the Mid-Atlantic region and get profoundly different stands of cover crops a few months later.
WASHINGTON, August 18, 2020 -- As the climate of the planet is changing, as evidenced by record-setting hot summers and extreme weather events, many researchers are looking to more renewable energy sources, such as solar and wind farms.
In a paper for the Journal of Renewable and Sustainable Energy
, by AIP Publishing, researchers investigate whether the power generated by solar and wind farms would differ between current and future climates.
What The Study Did: This study examined the association of depression with cannabis use among U.S. adults and the trends for this association from 2005 to 2016.
Authors: Deborah Hasin, Ph.D., of Columbia University Medical Center in New York, is the corresponding author.

A research team led by Hokto Kazama at the RIKEN Center for Brain Science (CBS) in Japan has combined brain imaging and models of brain activity to explain how smells can be generalized into categories. The team examined a region of the fly brain that plays a central role in forming olfactory memories and discovered clustered representations of mixtures and groups of odors that are conserved across individual flies. This study, published in Neuron, explains how varying odors are perceived similarly in different individuals.
HUNTINGTON, W.Va. - A common green apple vape flavor enhances nicotine reward, which could heighten reward and drug-seeking behavior, according to researchers at Marshall University.
ITHACA, N.Y. - When you search for something on the internet, do you scroll through page after page of suggestions - or pick from the first few choices?
Because most people choose from the tops of these lists, they rarely see the vast majority of the options, creating a potential for bias in everything from hiring to media exposure to e-commerce.
In a new paper, Cornell University researchers introduce a tool they've developed to improve the fairness of online rankings without sacrificing their usefulness or relevance.
The behaviours implied in the manipulation of food items by African elephants were correlated with the shape and size of these items. Despite a common ethogram, all the elephants showed different frequencies in the use of at least one behaviour.
