Serotonin can help promote human intimacy and romantic feelings

The judgments we make about the intimacy of other couples' relationships appear to be influenced by the brain chemical serotonin, reports a new study published in Biological Psychiatry.

Researchers develop Short-CGH method for preimplantation genetic screening

A Short Comparative Genomic Hybridisation method has been developed to carry out preimplantation genetic screening by analysing all chromosomes and transferring selected embryos to the recipient uterus in the same in vitro fertilisation cycle. This eliminates the need to freeze them.

Researchers create artificial cornea using pig and human stem cells

Researchers extracted pig corneal cells and replaced them with human stem cells. Thus, the University of Granada takes the lead in the making of bioartificial organs, a field so far led by the Hospital Gregorio Marañón in Madrid.

New report reveals toad brains may contain germ-fighting proteins

Frog and toad skins already are renowned as cornucopias of hundreds of germ-fighting substances. Now a new report in ACS's Journal of Proteome Research reveals that the toad brains also may contain an abundance of antibacterial and antiviral substances that could inspire a new generation of medicines.

Researchers report injectable gel can help treat arthritis

Some 25 million people in the United States alone suffer from rheumatoid arthritis or its cousin osteoarthritis, diseases characterized by often debilitating pain in the joints. Now researchers at Brigham and Women's Hospital report an injectable gel that could spell the future for treating these diseases and others.

African genital herpes strains are more infectious than the U.S. virus

Strains of genital herpes in Africa are far more virulent than those in the United States, researchers at Harvard Medical School report, a striking insight into a common disease with important implications for preventing HIV transmission in a region staggered by the HIV/AIDS epidemic.

Pharmaceuticals stored on space flights may have shorter shelf-life

Some of the Pharmaceuticals intended for the treatment of minor illnesses of astronauts in space may require special packaging and reformulation to remain stable for long periods in the space environment. That's according to Dr. Putcha and her colleagues from NASA, Johnson Space Centre. Their findings, published online in The AAPS Journal suggest that some of the pharmaceuticals stored on space flights may have shorter shelf-life than they do on Earth.

Nurses use ineffective strategy for adapting circadian clocks to night-time schedule

As many as 25 percent of hospital nurses go without sleep for at least 24 hours in order to adjust to working on the night shift, which is the least effective strategy for adapting their internal, circadian clocks to a night-time schedule.

Researchers temporarily turn off essential gene using RNAi technology

One way of discovering a gene's function is to switch it off and observe how the loss of its activity affects an organism. If a gene is essential for survival, however, then switching it off permanently will kill the organism before the gene's function can be determined. Researchers at Cold Spring Harbor Laboratory (CSHL) have overcome this problem by using RNA interference (RNAi) technology to temporarily turn off any essential gene in adult mice and then turn it back on before the change kills the animals.

Normal breast cells provide an innate defense mechanism against cancer

It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer - healthy cells.

Sea squirt study may help solve organ rejection problems in humans

Studies of the small sea squirt may ultimately help solve the problem of rejection of organ and bone marrow transplants in humans, according to scientists at UC Santa Barbara.

Researchers show how TET1 enzyme controls fetal development and fights cancer

To ensure normal fetal development and prevent disease, it is crucial that certain genes are on or off in the right time intervals. Researchers in Professor Kristian Helin's group at BRIC, University of Copenhagen, have now shown how the TET1 enzyme controls the activity of our genes. The results are just published in the journal Nature.

NIST's new reference can aid in Huntington's disease diagnosis

A new Standard Reference Material from the National Institute of Standards and Technology will help clinical genetics labs accurately diagnose Huntington's disease, an inherited degenerative brain disorder that usually begins between ages 35 and 50 and progressively leads to physical impairment, dementia and death.

Scientists link increase of calcium influx in brain neurons to long-term memory

Using advanced imaging technology, scientists from the Florida campus of The Scripps Research Institute have identified a change in chemical influx into a specific set of neurons in the common fruit fly that is fundamental to long-term memory.

Scientists identify filter neurons that can reduce 'brain clutter'

Until now, it has been assumed that people with diseases like ADHD, Tourette syndrome, obsessive compulsive disorder and schizophrenia - all of whom characteristically report symptoms of "brain clutter" - may suffer from anomalies in the brain's prefrontal cortex.

Researchers develop non-steroid based strategy for patients with COPD

Researchers at the Johns Hopkins Bloomberg School of Public Health have developed a non-steroid based strategy for improving the lung's innate immune defense and decreasing inflammation that can be a problem for patients with chronic obstructive pulmonary disease.
