Eating eggs reduces risk of type 2 diabetes, study indicates

Science Daily - Thu, 02/04/2015 - 12:18pm
Egg consumption may reduce the risk of type 2 diabetes, according to new research. Type 2 diabetes is becoming increasingly widespread throughout the world. Research has shown that lifestyle habits, such as exercise and nutrition, play a crucial role in the development of the disease. A new study has found that egg consumption was associated with a lower risk of type 2 diabetes as well as with lower blood glucose levels. Men who ate approximately four eggs per week had a 37 per cent lower risk of type 2 diabetes than men who only ate approximately one egg per week. This association persisted even after possible confounding factors such as physical activity, body mass index, smoking and consumption of fruits and vegetables were taken into consideration.

High-fat dairy products linked to reduced type 2 diabetes risk

Science Daily - Thu, 02/04/2015 - 12:18pm
Consumption of high-fat yoghurt and cheese are linked to a reduction in the risk of type 2 diabetes by as much as a fifth, according to new research. High meat consumption, on the other hand, is linked to a higher risk.

Unique observation in semiconductors: New charge transport phenomenon

Science Daily - Thu, 02/04/2015 - 12:18pm
Researchers have collaborated in the study of the movement of charges over interfaces of semiconductor materials. The group noticed a new kind of transport phenomenon for charges. In the phenomenon, a pair formed by a negative electron and a positive charge moves onto an interface, after which its 'message' is passed on to the other side of the interface, where it is carried on by a similar pair. The new theoretical result opens up interesting prospects for carrying out logical operations in electronics.

The brain-belly connection: Scientists find key genetic triggers in weight-regulating brain cells

Science Daily - Thu, 02/04/2015 - 12:16pm
The little voice inside your head that tells you to eat, or stop eating, isn’t a little voice – it’s actually a cluster of about 10,000 specialized brain cells. And now, scientists have found tiny triggers inside those cells that give rise to this “voice”, and keep it speaking throughout life.

Key mechanism identified in pediatric bone cancers that allows proliferation of tumor-forming stem cells

Science Daily - Thu, 02/04/2015 - 12:16pm
A particular molecular pathway permits stem cells in pediatric bone cancers to grow rapidly and aggressively, according to researchers. In the study, the investigators used human and mouse osteosarcomas to pinpoint the molecular mechanisms that inhibit the tumor-suppressive Hippo pathway. The researchers concluded that Sox2 represses the functioning of the Hippo pathway, which, in turn, leads to an increase of the potent growth stimulator Yes Associated Protein, known as YAP, permitting cancer cell proliferation.

Suicides: Not just a winter problem

Science Daily - Thu, 02/04/2015 - 12:16pm
A new article looks at seasonal suicide that tends to peak in the Spring months. "Whenever someone makes a conscious decision to attempt or complete suicide, often friends and family ask themselves what they could have done to prevent it," says one expert. "It's an alarming public health problem that needs to addressed in a clinically compassionate way being culturally sensitive to the needs of those seeking to find answers to their personal loss."

Focusing On Tech Alone, You Miss How Autonomous Driving Will Change Society

Slashdot - Thu, 02/04/2015 - 12:03pm
Hallie Siegel writes The way that consumers interact with and operate cars will transform most functions in commuting, travel, communications, car ownership, and many other as-yet unknown ways. Dieter Zetsche, chairman of Daimler and head of Mercedes-Benz Cars, said at this year's CES in Las Vegas: "Anyone who focuses solely on the technology has not yet grasped how autonomous driving will change our society." Robotics watcher Frank Tobe writes about how imagination is overtaking the ethics debate around autonomous cars."
