Adding alcohol to energy drinks leads to an increased urge to drink

Adding alcohol to energy drinks leads to an increased urge to drink

Public health advocates in recent years have become concerned not with the consumption of energy drinks by youth but also their joint consumption with alcohol by young adults. New research provides evidence of a mechanism through which energy drinks may increase binge drinking: combining energy drinks with alcohol increases people’s desire to keep drinking more than if they drank alcohol alone. Results will be published in the August 2014 online-only issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View. Continue reading

Mechanism that forms cell-to-cell catch bonds found by researchers

Mechanism that forms cell-to-cell catch bonds found by researchers

Certain bonds connecting biological cells get stronger when they’re tugged. Those bonds could help keep hearts together and pumping; breakdowns of those bonds could help cancer cells break away and spread. Those bonds are known as catch bonds and they’re formed by common adhesion proteins called cadherins. Continue reading

Brain signals link physical fitness to better language skills in kids

Brain signals link physical fitness to better language skills in kids

Children who are physically fit have faster and more robust neuro-electrical brain responses during reading than their less-fit peers, researchers report. These differences correspond with better language skills in the children who are more fit, and occur whether they’re reading straightforward sentences or sentences that contain errors of grammar or syntax. The new findings, reported in the journal Brain and Cognition , do not prove that higher fitness directly influences the changes seen in the electrical activity of the brain, the researchers say, but offer a potential mechanism to explain why fitness correlates so closely with better cognitive performance on a variety of tasks.

Researchers see stem cells take key step toward development: A first

Researchers see stem cells take key step toward development: A first

The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory. University of Illinois researchers, in collaboration with scientists at Notre Dame University and the Huazhong University of Science and Technology in China, published their results in the journal Nature Communications Continue reading

Major discovery on the mechanism of drug resistance in leukemia and other cancers

Major discovery on the mechanism of drug resistance in leukemia and other cancers

A mechanism that enables the development of resistance to Acute Myeloid Leukemia (AML) anticancer drugs, thereby leading to relapse, has been identified by Kathy Borden of the University of Montreal’s Institute for Research in Immunology and Cancer (IRIC) and her collaborators. Kathy Borden is a Principal Investigator at IRIC and a professor at the university’s Department of Pathology and Cell Biology. Continue reading

Insights into genetics of cleft lip

Insights into genetics of cleft lip

Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, have identified how a specific stretch of DNA controls far-off genes to influence the formation of the face. The study, published today in Nature Genetics, helps understand the genetic causes of cleft lip and cleft palate, which are among the most common congenital malformations in humans. “This genomic region ultimately controls genes which determine how to build a face and genes which produce the basic materials needed to execute this plan,” says François Spitz from EMBL, who led the work Continue reading

Measuring fine dust concentration via smartphone

Measuring fine dust concentration via smartphone

Big cities in the smog: Photos from Beijing and, more recently, Paris clearly illustrate the extent of fine dust pollution. But what about our direct environment? What is the pollution concentration near our favorite jogging route? Continue reading

New sensor could light the way forward in low-cost medical imaging

New sensor could light the way forward in low-cost medical imaging

New research published today in Nature’s Scientific Reports , identifies a new type of light sensor that could allow medical and security imaging, via low cost cameras. The team of researchers from the University of Surrey have developed a new ‘multispectral’ light sensor that detects the full spectrum of light, from ultra-violet (UV), to visible and near infrared light Continue reading

Galectins direct immunity against bacteria that employ camouflage

Galectins direct immunity against bacteria that employ camouflage

Our bodies produce a family of proteins that recognize and kill bacteria whose carbohydrate coatings resemble those of our own cells too closely, scientists have discovered. Called galectins, these proteins recognize carbohydrates from a broad range of disease-causing bacteria, and could potentially be deployed as antibiotics to treat certain infections. Continue reading
