Social engagement transforms white fat into energy-burning brown fat

When mice are given a more engaging place to live with greater opportunities for social stimulation, some of their energy-storing white fat is transformed to energy-burning brown fat. As a result, the animals expend more energy and lose weight even as they eat more. The findings reported in the September Cell Metabolism, a Cell Press publication, point to the powerful effect that animals' social and physical environments can have on their metabolisms.

Scientists invent new system that uses magnetism to purify hybrid nanoparticles

A team of Penn State University scientists has invented a new system that uses magnetism to purify hybrid nanoparticles -- structures that are composed of two or more kinds of materials in an extremely small particle that is visible only with an electron microscope.

Biochemists reveal interaction between tumor suppressor protein and chaperone

Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.

NJIT to honor electrical engineer for nanotechnology research

What do brilliantly colored glass, advanced batteries, and innovative technology for the regulation of brain functions have in common? They are nano-scale structures far smaller than the wavelengths of energy coursing through them in different regions of the electromagnetic spectrum, said NJIT Professor Haim Grebel.

Study: Protein's structural arrangement can change its signaling function

In a joint study, scientists from the California and Florida campuses of The Scripps Research Institute have shown that changes in a protein's structure can change its signaling function and they have pinpointed the precise regions where those changes take place.

Researchers identify new genetic cause of inherited Parkinson's disease

A large team of international researchers have identified a new genetic cause of inherited Parkinson's disease that they say may be related to the inability of brain cells to handle biological stress.

Loss of estrogen receptor alpha protein may lead to metabolic syndrome

UCLA researchers demonstrated that loss of a key protein that regulates estrogen and immune activity in the body could lead to aspects of metabolic syndrome, a combination of conditions that can cause Type 2 diabetes, atherosclerosis and cancer. Called estrogen receptor alpha, this protein is critical in regulating immune system activity such as helping cells suppress inflammation and gobble-up debris.

Human brain places more value on winning in a social setting

A new USC study explains why people take stupid chances when all of their friends are watching that they would never take by themselves. According to the study, the human brain places more value on winning in a social setting than it does on winning when you're alone.

Scientists discover 29 new genetic variants linked with MS

Multiple sclerosis is primarily an immunological disease. Scientists at Charité - Universitätsmedizin Berlin and Max-Delbrück-Center for Molecular Medicine (MDC) have in succeeded, in collaboration with 23 research teams from 15 different countries, in discovering a total of 29 new genetic variants that are involved in the genesis of multiple sclerosis (MS), an inflammatory disease of the nervous system.

International researchers to assess role of pre-clinical animal models in drug discovery

The New York Academy of Sciences and the Global Medical Excellence Cluster (GMEC), in collaboration with Imperial College London and King's College London, will host a two-day scientific conference, "Animal Models and Their Value in Predicting Drug Efficacy and Toxicity," that will provide a forum to critically examine the role of pre-clinical animal models in drug discovery.

Glioma stem cells can change their metabolic state at will, finds study

The metabolic state of glioma stem cells, which give rise to deadly glioblastomas, is significantly different from that of the brain cancer cells to which they give birth, a factor which helps those stem cells avoid treatment and cause recurrence later.

Scientists discover two opposing neuronal regulatory circuits for generation, elimination of fear

Emotional balance is regulated by molecular factors behind stress response. When healthy people are faced with threatening situations, they react with a suitable behavioural response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer from anxiety.
