Umbilical cells help eye's neurons connect

Wed, 25/11/2015 - 1:43am
Cells isolated from the human umbilical cord have been shown to produce molecules that help retinal neurons from the eyes of rats grow, connect and survive. The findings implicate one family of molecules in particular -- thrombospondins - that may have therapeutic potential for the treatment of degenerative eye diseases.

Betrayals of trust: Human nature's dark side may have helped us spread across the world

Wed, 25/11/2015 - 1:43am
New research suggests that betrayals of trust were the missing link in understanding the rapid spread of our own species around the world. Moral disputes motivated by broken trust and a sense of betrayal became more frequent and motivated early humans to put distance between them and their rivals.

When exercise is unhealthy for the heart: How heart problems and sudden cardiac death occur with endurance exercise

Tue, 24/11/2015 - 10:03pm
Endurance exercise accelerates the development of heart problems in individuals with a particular genetic mutation, a new study finds. In mice with a mutated version of desmoplakin, a protein that maintains the heart wall, exercise made the heart walls come apart sooner. The findings offer insight into how to best manage exercise in individuals with the mutation.

Carbon content of temperate forests overestimated, study suggests

Tue, 24/11/2015 - 10:02pm
Digital measurements of millions of trees indicate that previous studies likely overestimate the amount of carbon stored by temperate US forests, according to a new study.

Volcanic rocks hold clues to Earth's interior

Tue, 24/11/2015 - 10:02pm
Earth's deep interior transport system explains volcanic island lava complexities, report scientists. Studies of rocks found on certain volcanic islands, known as ocean island basalts, have revealed that although these erupted rocks originate from Earth's interior, they are not the same chemically.

Mars once had a moderately dense atmosphere

Tue, 24/11/2015 - 10:02pm
Scientists suggest that 3.8 billion years ago, Mars might have had only a moderately dense atmosphere. The scientists have identified a photochemical process that could have helped such an early atmosphere evolve into the current thin one without creating the problem of 'missing' carbon and in a way that is consistent with existing carbon isotopic measurements.

Native Americans have decreased access to kidney transplants

Tue, 24/11/2015 - 8:54pm
Native Americans have decreased access to kidney transplants and are more likely to die while waiting for a kidney than whites according to new research. Long-term survival outcomes in Native Americans who did receive a kidney transplant were worse than whites, according to a new study.

The myth about l-trypophan in turkey

Tue, 24/11/2015 - 7:38pm
Turkey itself doesn’t make you sleepy after a Thanksgiving meal. What makes you sleepy is eating very large quantities of turkey, stuffing, potatoes and pie. Turkey does contain tryptophan, but so do yogurt, eggs, fish, cheese and other meats.

Want honesty? Make it the easiest choice, suggests research

Tue, 24/11/2015 - 7:36pm
We're more likely to do the right thing in situations of moral conflict when it requires little to no effort, new research confirms. If income information is automatically entered into our tax return, we may be less likely to alter it to something that is incorrect once it's there. However, the passive response can promote cheating, too.

A new green power source

Tue, 24/11/2015 - 7:36pm
To limit climate change, experts say that we need to reach carbon neutrality by the end of this century at the latest. To achieve that goal, our dependence on fossil fuels must be reversed. But what energy source will take its place? Researchers report that they just might have the answer: blue-green algae.

Winter season reverses outcome of fruit fly reproduction

Tue, 24/11/2015 - 7:36pm
Male fruit flies could find their chances of fathering offspring radically reduced if they are last in the queue to mate with promiscuous females before winter arrives, according to new research.

Army ants' 'living' bridges span collective intelligence, 'swarm' robotics

Tue, 24/11/2015 - 7:35pm
Researchers report for the first time that the 'living' bridges army ants of the species Eciton hamatum build with their bodies are more sophisticated than scientists knew. The ants automatically assemble with a level of collective intelligence that could provide new insights into animal behavior and even help in the development of intuitive robots that can cooperate as a group.

Mars to lose its largest moon, Phobos, but gain a ring

Tue, 24/11/2015 - 7:35pm
Mars' largest moon -- one of only two in our solar system moving inward towards its planet -- will eventually be torn apart by tidal forces and distributed in a ring around the planet, a study of the cohesiveness of Phobos has concluded. This would take about 10-20 million years, and the ring will persist for up to 100 million years before the dust falls into Mars' atmosphere and burns up as 'moon' showers.

People who rely on their intuition are, at times, less likely to cheat

Tue, 24/11/2015 - 7:35pm
In psychological studies, intuition, or 'gut instinct,' is the ability to understand something immediately, without the need for conscious reasoning. Now, a new study has determined that individuals who are prone to trust their instincts may at times be less likely to commit immoral acts. Findings indicate that people who tend to rely on their intuition are less likely to cheat after reflecting on past experiences during which they behaved immorally.

Safety last?

Tue, 24/11/2015 - 7:33pm
With the globalization of our food supply, food safety issues are a major concern for both public health and for the food industry. Media and industry warn consumers of major recalls and problems with food items, but do consumers listen? In this new article researchers demonstrated that consumers are reluctant to respond to food safety risks if the recommendations interfere with their existing habits.

Investigational drug may prevent life-threatening muscle loss in advanced cancers

Tue, 24/11/2015 - 7:33pm
New data describes how an experimental drug can stop life-threatening muscle wasting (cachexia) associated with advanced cancers and restore muscle health. The experimental agent, known as AR-42 while in testing, was tested in preclinical studies.

Decarbonizing tourism: Would you pay US$11 for a carbon-free holiday?

Tue, 24/11/2015 - 7:33pm
The damaging effects of carbon dioxide emissions from tourism could eventually be eliminated if travelers paid just US$11 per trip, according to a new study. Global tourism is largely dependent on fossil fuel energy, and emits more carbon dioxide than than all but five countries of the world. Recent estimates conclude that tourism, including transport, accommodation, and leisure activities contributed close to 5 percent of total human-made emissions of carbon dioxide worldwide.
