Male mammoths were good at falling in holes, says new research

Male mammoths — much like male humans — were clumsy galoots who didn’t look where they walking and fell into holes, researchers have established. Scientists led by Love Dalen of the Swedish Museum of Natural History in Stockholm set out to determine the gender of 98 sets of mammoth remains collected from various parts of Siberia. Unexpectedly, they found that ... Read More »

Bees can be left or right-handed like humans, says new research

Bees can be left or right-handed like humans, says new study

Scientists at The University of Queensland’s Queensland Brain Institute have discovered that bees can have a preference for left or right – influencing their decisions while they navigate obstacles in flight. Professor Mandyam (Srini) Srinivasan said the study showed that honeybees displayed handedness that varied from individual to individual. “Unlike humans, who are mostly right-handed, some bees display a strong ...

Scientists discover belt of dust surrounding nearest star

Scientists discover belt of dust surrounding nearest star

Scientists have detected at least one cold dust belt surrounding the closest star to the Sun, Proxima Centauri. The presence of such a feature suggests there might be more than one planet orbiting Proxima. Proxima Centauri is the closest star to the Sun. It is a faint red dwarf lying just four light-years away in the southern constellation of Centaurus ... Read More »

NASA: Earth's ozone hole shrivels to smallest since 1988

Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced today. According to NASA, the ozone hole reached its peak extent on Sept. 11, covering an area about two and a half times the size of the United States – ... Read More »

Human brain not as exceptional as thought, says new research

Human brain not as exceptional as thought, says new research

While it has been long assumed that humans commit more energy to powering their brains than other animals, researchers have now determined this is not the case. It turns out that some animals, such as the tiny pygmy marmoset, dedicate just as much energy to their brains as people do. Published in the Journal of Human Evolution, Doug Boyer and ...

Research: Are cities affecting evolution?

Study: Are cities affecting evolution?

The recent uproar about seats on a British Airways flight crawling with bedbugs is only one of the unintended consequences that urbanization worldwide has on evolution, say Marc Johnson, an associate professor of biology at the University of Toronto Mississauga, and Jason Munshi-South, who is an associate professor of biological sciences at Fordham University. “As we build cities, we have ...

Climate Change Could Decrease Sun’s Ability To Disinfect Lakes (Research)

Climate Change Could Decrease Sun's Ability To Disinfect Lakes, Says New Study

A new research published in journal Scientific Reports has revealed another harmful effect of climate change. Increasing organic runoff as a result of climate change may be reducing the penetration of pathogen-killing ultraviolet (UV) sunlight in inland lakes, rivers, and coastal waters, according to a new study in the journal Scientific Reports. The findings, from a team including researchers at Rensselaer Polytechnic ... Read More »

Dinosaur-killing asteroid cooled Earth more than thought, scientists say

Asteroid That Killed Dinosaurs Also Made Earth Freezing, Researchers Say

The Chicxulub asteroid impact that many believed wiped out the dinosaurs released far more climate-altering gas into the atmosphere than originally thought, researchers have revealed. It reveals for the first time how much sulfur and carbon dioxide gas was ejected into Earth’s atmosphere from vaporized rocks immediately after the event – triggering a ‘superwinter’. “Many climate models can’t currently capture ...
