US woman Eunice Foote only now receiving credit for first identifying greenhouse effectThis year marks the 200th anniversary of the birth of Eunice Foote, a pioneer in climate research of whom few people have heard. She showed that water vapour and carbon dioxide helped to heat Earth’s atmosphere, and realised that when the atmosphere had higher levels of carbon dioxide it made the climate much...
Michael James was boarding over the last two windows of his house on Florida's east coast. The first gusty blasts of wind were announcing Hurricane Dorian's imminent arrival, and most residents had fled. But James, an old hand at this, knew he had a few hours to go before leaving.
The explosion marked the third failure involving a rocket at the Iranian center, which has raised suspicions of sabotage in Iran’s space...
A new Columbia Engineering study indicates that the world will experience more frequent and more extreme drought and aridity than currently experienced in the coming century, exacerbated by both climate change and land-atmosphere processes. The researchers demonstrate that concurrent soil drought and atmospheric aridity are largely driven by a series of land-atmosphere processes and feedback...
Diversity is a hallmark of life and it shows up in unexpected places. A multi-national team of evolutionary biologists investigated how two types of poison frog co-exist when only one might be expected. Their innovative study uncovers conditions where diversity flourishes against the odds, and offers new perspectives on chemical defense. The findings were published in the Proceedings of the...
The ability to detect the direction of someone's gaze is not unique to humans, as had been previously thought, according to new research.
Newly digitized vintage film has doubled how far back scientists can peer into the history of underground ice in Antarctica, and revealed that an ice shelf on Thwaites Glacier in West Antarctica is being thawed by a warming ocean more quickly than previously thought. This finding contributes to predictions for sea-level rise that would impact coastal communities around the world.
The last “sexy” theory is that the space plane is basically a spy satellite with the ability to return to Earth and have its optical sensors periodically upgraded. The X-37 has orbited over some interesting locations, including North Korea, China, ISIS-held territory and Iran. U.S. optical spy satellites are, however, quite large—the size of a school bus—and the X-37’s payload bay is far...
Where a mother lives and the temperature outside while she is pregnant, among other environmental factors, can impact whether her child is prehypertensive or hypertensive during childhood, according to a new study.
Even if you are a non-smoker who exercises and has no genetic predisposition to cardiovascular disease, skimping on sleep -- or getting too much of it -- can boost your risk of heart attack, according to a new study of nearly a half-million people.
Three months after Elon Musk’s SpaceX launched the first set of what will be a broadband-providing constellation of satellites, other operators are already veering to keep their own spacecraft out of harm’s way. The European Space Agency tweeted Monday that it fired the thrusters on its Earth observation satellite Aeolus to avoid a potential collision with one of SpaceX’s...
Dog brain structure varies across breeds and is correlated with specific behaviors, according to new research published in JNeurosci. These findings show how, by selectively breeding for certain behaviors, humans have shaped the brains of their best friends.
Chronic cocaine use changes gene expression in the hippocampus, according to new research in mice.
Hurricane Dorian unleashed massive flooding across the Bahamas on Monday, pummeling the islands with so much wind and water that authorities urged people to find floatation devices and grab hammers to break out of their attics if necessary.
In the two years since the Grand Canyon approved a plan to reduce the number of bison roaming in the national park, the herd has only grown in size.
Monster storm Dorian came to a near stand-still over the Bahamas Monday, prolonging the agony as surging seawaters and hurricane winds made a shambles of low-lying island communities and spurred mass evacuations along the US east coast.
Hurricane Dorian, which slammed the Bahamas early Monday as a catastrophic Category 5 storm, is packing remarkably strong winds — but the storm itself is crawling along, moving at a mere 1 mile per hour early Monday before slowing to “stationary” as of Monday afternoon. The storm’s glacial pace will result in even more devastation, meteorologists say. With sustained winds...
Space-starved Singapore has expanded outwards by building into the sea and upwards by constructing high-rises but planners are now looking underground as they seek new areas for growth. Singapore has already built an underground highway and state-of-the-art air conditioning system, but is now looking to house more facilities beneath the surface in order to optimise land use above...
Congestion causes the mass of tubes and motors that form chromosome-dividing spindles to move at full speed instead of slowing to a crawl, new research reveals.
Climate change could negatively impact banana cultivation in some of the world's most important producing and exporting countries, a study has revealed.
The human digestive tract is home to thousands of different strains of bacteria. Many of these are beneficial, while others contribute to health problems such as inflammatory bowel disease. Researchers have now isolated and preserved samples of nearly 8,000 of these strains, while also clarifying their genetic and metabolic context.
Biologists from the University of Alberta studied the Lake Hazen watershed in Nunavut and found rivers with glacial meltwater are carbon...
Researchers at The University of Manchester discovered that atomically- thin micas—the name given to a type of common mineral found in soil—are excellent proton conductors. This surprising result is important for the use of 2-D materials in applications such as fuel cells and other hydrogen-related technologies.
