Scientists find method to pick noncompetitive animals, improve production

...ists show that aggressiveness and all other traits affecting social interactions are inherited and can be estimated. They also found that by using the new tool they were able to confirm two-thirds more inherited trait variations that impact social interactions than could be identified with classical selection ...

Exploring the molecular origin of blood clot flexibility

..., such as antibodies, bind specifically to fibrin, affecting clot structure. The idea would be to use such compounds in people to alter the properties of the clot, so it can be less obstructive and more easily dissolved. In the future, the researchers will examine other processes at the molecular and fiber ...

Antivirals effectively curb influenza virus

...s could be the key, with zanamivir not reaching or affecting influenza virus in the nose. While both antivirals reduced cough, in earlier studies inhaled zanamivir did not significantly reduce nasal symptoms. In the paper the authors discussed the possibility that infectious droplets inhaled and exhaled from t...

Nanotechnology shows promise as next wrinkle fighter

...articles in the film can be stress busters without affecting the neighboring layers. "The wrinkle-free films will automatically absorb or deflect the stress and stay flat, just as they are after formation," he said. Nanoparticle films wouldn't be a face-lift itself, but Ilsoon sees the possibility in a ...

Inhibiting blood to save the brain

...d block the damaging effects of fibrinogen without affecting its beneficial blood coagulation. Studying a mouse model, the researchers identified a specific receptor called Mac-1 that is expressed by microglial cells and binds to fibrinogen. Mice expressing a mutant form of fibrinogen that failed to bind Mac...

Microfluidic chip helps solve cellular mating puzzle

... level of control we can achieve on the conditions affecting just a few cells is unbelievable," Levchenko said. "This is far beyond what you can do in a traditional biology lab dish that’s filled with a large colony of cells." Using cameras attached to a microscope, the researchers were able to view a micro...

Moonlighting enzyme linked to neurodegenerative disease

...onal Institutes of Health because of its rarity -- affecting one in 40,000. It is associated with a deficiency of frataxin, a protein that balances iron in mitochondria, which are the structures that convert nutrients into energy for cells. A new Mayo Clinic study published in the April issue of the Proceeding...

Satellites shed light on global warming

...in which these near-invisible waves are capable of affecting phytoplankton, as they may be providing them with an input of nutrient-rich water from the deep ocean as well as moving them around. These findings are then compared with the effect of waves in models, helping to make the models more realistic, which...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...rent and travels no more than 10 to 15km offshore, affecting only the inner Great Barrier Reef Lagoon and the inner reef corals. Images captured by CSIRO show large plumes of terrestrial material following unconventional patterns and travelling quite fast as far as 65 to 130km, to the outer reef and, in som...

Cholera pathogen reveals how bacteria generate energy to live

...trace and its concentration can be changed without affecting pH, which is a complication with protons. "It’s a very good system to understand this very basic mechanism charging this battery to create energy," she said. In order to learn how the enzyme works, researchers are trying to get an idea of its thre...

New approach could lower antibiotic requirements by 50 times

...or example is rapidly spreading through hospitals, affecting more than 8,000 people in the UK every year. MRSA infection can lead to septic shock and death. ...

New imaging technique tracks traffic patterns of white blood cells

...mon inherited blood disorder in the United States, affecting 72,000 Americans according to the National Institutes of Health (NIH). Sickle Cell disease is a blood disorder that affects hemoglobin, a protein inside red blood cells that help carry oxygen throughout the body. Abnormal hemoglobin polymerizes, and...

Researchers show that veins stiffen as we age

...d patients with information about the risk factors affecting heart disease and the benefits of exercise. Then, during his postdoctoral training at Boston's Beth Israel Deaconess Medical Center, he worked with patients who were unable to stand without getting dizzy. And that began his research on veins. Today...

A potential biological cause for sudden infant death syndrome

...eath in American infants after the newborn period, affecting 0.67 in 1,000 live-born babies. Although epidemiologic studies have identified risk factors for SIDS, such as putting babies to sleep on their stomachs, and protective factors like pacifier use, there has been little understanding of SIDS's biologic ...

Antibiotic inhibits cancer gene activity

...iomycin A, that specifically targets FoxM1 without affecting other cell functions. In further experiments in tissue cultures, the researchers found that siomycin A induced cancer cells, but not normal cells, to commit suicide in a process called apoptosis. The new screening technique, Gartel said, gives re...

Computer with brain connections changing quality of life of paralyzed

...ALS is a progressive disease that destroys neurons affecting movement. The study appears in the latest issue of Psychophysiology. The article reviews the usefulness of currently available brain-computer –interfaces (BCI), which use brain activity to communicate through external devices, such as computers. The...

Older fathers more likely to have autistic children

...ectrum disorders, have become increasingly common, affecting 50 in every 10,000 children as compared with five in 10,000 two decades ago. This increase is partially due to higher levels of awareness and changes in diagnosis processes, but could also reflect an increase in incidence of autism, according to the...

Diabetes slows nerve recovery after heart transplant

...own major risk factor of heart disease, negatively affecting the heart's contraction and rhythm, said Bengel. Future research will need to focus on how regeneration of sympathetic nerves can be facilitated and how changes of the sympathetic nerve integrity in the heart are interrelated with changes of progn...
