Plant hemoglobins: Oxygen handlers critical for nitrogen fixation
Hemoglobins, key components of our blood, are ancient proteins with well-known roles in oxygen transport and respiration in animals. Hemoglobins are also present in plants and bacteria, but until now the physiological role of plant hemoglobins has been unclear. A group of researchers reveal this week that one such mysterious plant hemoglobin serves to assist in the fixation of nitrogen in the roo...Getting an evolutionary handle on life after reproduction
Since many animals live beyond their fertile years, biologists have searched for evolutionary clues to this extended lifespan. What role, if any, does natural selection play in the evolution of the postreproductive lifespan? For natural selection to shape the twilight years, postreproductive females should contribute to the fitness of their offspring or relatives, a hypothesis called the...Bio-Stack Twister II Microplate Handler from BioTek Instruments

Patients experiencing a panic disorder may benefit more from treatment combining cognitive behavioral therapy with medication instead // of the care usually offered by physicians. Panic disorder is one of the most disabling and costly anxiety disorders. In the study, 232 patients meeting the criteria for panic disorder were randomly assigned to receive treatment as usual or a treatment c...Mouth Infection better handled with new discovery
Research has proved that a new drug named histatin, a naturally occurring antifungal agent in saliva kills the fungus- Candida albicans,// which is responsible for most HIV-related oral infections. It is known that candidiasis, also known as thrush, is a disease characterized by whitish spots and ulcers on the membranes of the mouth, tongue and throat. It primarily affects people with w...Obesity better handled with gastric bypass surgery
A few years ago, 43-year-old Patrick Deuel of Nebraska, was slated for a slow but sure death, weighing in at 486 kg, suffering from diabetes //and unable to sit up or even turn over in bed. Deuel is now half the man he used to be, as he lost more than 200 kg after undergoing an operation that is becoming increasingly popular among morbidly obese Americans. The acclaimed so...Innovative yeast genome may handle Cancer Clues
