NASA scientists are tracking the upcoming Halloween flyby of asteroid 2015 TB145 with several optical observatories and the radar capabilities of the agency’s Deep Space Network at Goldstone, California. The asteroid will fly past Earth at a safe distance slightly farther than t

On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph. In the study published today in the journal Biology Letters, the researchers describe ho

As debate roils over EPA regulations proposed this month limiting the release of the potent greenhouse gas methane during fracking operations, a new University of Vermont study funded by the National Science Foundation shows that abandoned oil and gas wells near fracking sites can be

In 2011, satellite images of the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had expected. Scientists supposed that the ecosystem’s high annual precipitat

<!– –> Diesel fumes may be reducing the availability of almost half the most common flower odours that bees use to find their food, new research has found. The new findings suggest that toxic nitrous oxide (NOx) in diesel exhausts could be having an even greater effe

<!– –> Scientists have projected that the onset of spring plant growth will shift by a median of three weeks earlier over the next century, as a result of rising global temperatures. The results, published today (Wednesday 14th October), in the journal Environmental

New research by biologists at the University of York shows that plant and insect diversity is more loosely linked than scientists previously believed. Insects and flowering plants are two of the most diverse groups of organism on the planet. For a long time the richness of these two l

The history of wildfires over the past 2,000 years in a northern Colorado mountain range indicates that large fires will continue to increase as a result of a warming climate, according to a new study led by a University of Wyoming doctoral student. “What our research shows is that ev

Thirty-one percent of cactus species are threatened with extinction, according to the first comprehensive, global assessment of the species group by IUCN and partners, published today in the journal Nature Plants.  This places cacti among the most threatened taxonomic groups assessed
