Don't forget plankton in climate change models, says study

Posted: 27 Nov 2015 07:23 AM PST

Globally, phytoplankton absorb as much carbon dioxide as tropical rainforests and so understanding the way they respond to a warming climate is crucial, say scientists.

Scientists get first glimpse of black hole eating star, ejecting high-speed flare

Posted: 27 Nov 2015 07:17 AM PST

An international team of astrophysicists has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light.

Rapid plankton growth in ocean seen as sign of carbon dioxide loading

Posted: 26 Nov 2015 01:50 PM PST

A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean.

A new form of real gold, almost as light as air

Posted: 25 Nov 2015 07:47 AM PST

Researchers have created a new type of foam made of real gold. It is the lightest form ever produced of the precious metal: a thousand times lighter than its conventional form and yet it is nearly impossible to tell the difference with the naked eye. There are many possible applications.

Extinction is key to terrestrial vertebrate diversity, new research reveals

Posted: 23 Nov 2015 05:57 PM PST

Periods of high extinction on Earth, rather than evolutionary adaptations, may have been a key driver in the diversification of amniotes (today's dominant land vertebrates, including reptiles, birds, and mammals), according to new research.

Functional human liver cells grown in the lab

Posted: 26 Nov 2015 07:43 AM PST

A new technique for growing human hepatocytes in the laboratory has now been described by a team of researchers. This groundbreaking development could help advance a variety of liver-related research and applications, from studying drug toxicity to creating bio-artificial liver support for patients awaiting transplantations.

Global warming will be faster than expected

Posted: 26 Nov 2015 07:40 AM PST

Global warming will progress faster than what was previously believed. The reason is that greenhouse gas emissions that arise naturally are also affected by increased temperatures. This has been confirmed in a new study that measures natural methane emissions.

New test may improve diagnosis, treatment of pancreactic cancers

Posted: 23 Nov 2015 05:34 PM PST

Collecting blood samples from the portal vein can provide much more information about pancreatic cancer than taking blood from vein in the arm. Researchers found circulating tumors cells in 100 percent of 18 patients with suspected tumors in the pancreas and bile ducts. Standard samples detected tumors cells in only four patients.

High-fat diet prompts immune cells to start eating connections between neurons

Posted: 23 Nov 2015 05:31 PM PST

When a high-fat diet causes us to become obese, it also appears to prompt normally bustling immune cells in our brain to become sedentary and start consuming the connections between our neurons, scientists say.

New species of early anthropoid primate found amid Libyan strife

Posted: 23 Nov 2015 05:31 PM PST

A previously unknown anthropoid primate -- a forerunner of today's monkeys, apes and humans -- has been found in Libya. Researchers have dubbed their new find Apidium zuetina.

Blood from small children 'remembers' prenatal smoking exposure

Posted: 23 Nov 2015 05:31 PM PST

Blood taken from children up to the age of five contains molecular evidence about whether their mothers smoked during pregnancy, shows new research.
