Poor sleep causes weight gain, susceptibility to diabetes Posted: 03 Jan 2015 04:24 AM PST People who suffer breathing and heart rate abnormalities, called obstructive sleep apnea, are likely to develop diabetes, and the risk increases if they have a hereditary proclivity, scientists report.

Defects in solar cells made of silicon identified Posted: 02 Jan 2015 02:27 PM PST A researcher has focused recent study on "defects found on silicon and their impact on the efficiency of solar cells made with this material."

New information on environmental impacts of stump wood energy through 3-D modeling Posted: 02 Jan 2015 08:33 AM PST Tree stumps and root systems are a significant but controversial source of bioenergy in Finland due to their environmental impacts. Now Finnish and Norwegian researchers have developed a new method that can produce accurate three-dimensional (3D) models of recovered stumps and root systems. These models provide new information on the impacts of stump wood energy on the carbon sink capacity of forests, the biodiversity of forest nature and the soil structure of recovery areas. Tree stumps and root systems account for approximately 15% of the energy wood harvested from Finnish forests. Tree stumps are recovered from one in every ten clearcutting areas, totalling some 10,000–20,000 hectares annually, which is, at its highest, equivalent to an area the size of Helsinki.

Technology innovations spin NASA's SMAP into space Posted: 02 Jan 2015 05:44 AM PST Scheduled for launch on Jan. 29, 2015, NASA's Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth's soils with an unprecedented accuracy and resolution. The instrument's three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.

Innate behaviour determines how we steer our car Posted: 02 Jan 2015 04:16 AM PST A 70 year old mystery in traffic research has been solved: an until now inexplicable jerkiness when we steer a vehicle. The discovery may lead to safety systems in cars that can correct dangerous steering movements before they occur. "With the driver model I have developed, it is possible to predict what drivers are going to do with the steering wheel before they do it. It is possible to predict how far the driver is going to turn the wheel, right when the person starts a wheel-turning movement. It's like looking into the future," says a researcher.

Scientist look for nanostructures that allow compatibility between metal, human bone tissues   Posted: 02 Jan 2015 04:15 AM PST One of the goals of Cimav specialists is to develop biomedical implants needed in Mexico, as the ones existing in the domestic market are usually manufactured abroad.

Time to reactivate nuclear energy in Mexico? Posted: 02 Jan 2015 04:15 AM PST A Mexican scientist has argued that nuclear energy is a real alternative to mitigate climate change damage from fossil fuel combustion in the country.

Stress can be a factor for developing diabetes, autoimmune diseases Posted: 02 Jan 2015 04:15 AM PST Recurring stress can trigger insulin resistance, hypertension, abdominal fat deposition, researchers say.

First baby of the new year race is real, says OB/GYN Posted: 30 Dec 2014 01:09 PM PST As the countdown for the new year begins, so does the race for the first baby of the new year. "The race to have the first baby is something all hospitals share enthusiasm for, especially in large cities like Chicago, and, unfortunately, not all hospitals play fair," said and OB/GYN.

Readiness to change is a vital facet to committing to New Year's resolutions Posted: 30 Dec 2014 10:29 AM PST Whether it is losing weight or quitting smoking, one employee wellness director says it can be done with the will to do so. About half of the most popular resolutions made each year are health-related, according to the United States government. In addition to losing weight and quitting smoking, they include eating healthier foods, getting fit, managing stress and drinking less alcohol.

Resolved to lose weight in 2015? Here are five bad strategies to avoid Posted: 30 Dec 2014 10:29 AM PST Is your New Year's resolution to lose weight? Here are five bad strategies to avoid, provided by an American physician.

New test measures doctors' ability to deliver patient-centered care Posted: 30 Dec 2014 07:19 AM PST When health care providers take patients' perspectives into consideration, patients are more likely to be actively engaged in their treatment and more satisfied with their care. This is called patient-centered care. Recently, researchers have developed a credible tool to assess whether medical students have learned and are applying specific behaviors that characterize patient-centered care.
