Unlike other mammals, newborn dolphins and orcas stay active 24/7 during first months of development
If you thought the sleep-deprived months with your newborn were tough, pity the poor mother dolphin or killer whale. Reporting in the June 30 edition of the peer-reviewed journal Nature, UCLA/Veterans Affairs neuroscientists report a developmental pattern in bottlenose dolphins and killer whales that is unique from other mammals, with calves of both species active 24 hours a day during th...FDA: 'Highly Unlikely' Green Tea Lowers Cancer Risk
The new surgical assistant at the University of North Carolina Hospitals arrived in February sporting three arms, a computerized brain and a glowing track record in helping to repair heart valves, remove cancerous prostates, bypass blocked coronary arteries and perform gastric bypass operations for morbid obesity. The new arrival is a robotic machine, the da Vinci Surgical System, manufact...Medical experts: US unlikely to have enough vaccines to stop avian flu
A group of medical experts who attended a national avian flu conference last fall believe there is little chance the United States will be able to manufacture and stockpile enough vaccine or antiviral medication to stop a bird flu pandemic should the virus mutate into a form that can be spread easily from human to human, according to a survey led by researchers at Carnegie Mellon University. The...Access to antiretrovirals unlikely to reduce HIV infection rates
A new study by Rebecca Baggaley, Neil Ferguson, and Geoff Garnett (of Imperial College London) suggests that the HIV epidemic in poor countries will not be controlled through antiretroviral drugs alone, even if universal access is achieved. As they demonstrate in an article in the open-access international medical journal PLoS Medicine, without additional prevention methods such as counseling pat...Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study
When given extra shots of the plant steroid brassinolide, plants "pump up" like major league baseball players do on steroids. Tracing brassinolide's signal deep into the cell's nucleus, researchers at the Salk Institute for Biological Studies have unraveled how the growth-boosting hormone accomplishes its job at the molecular level. The Salk researchers, led by Joanne Chory, a professor i...Storytelling makes a comeback in an unlikely place
Lori Silverman, owner of the consulting firm Partners for Progress and co-author of the organizational performance book Criti...Fibroids unlikely to Turn Cancerous
Women should get a second medical opinion if they are told to consider a hysterectomy because they have fibroid tumors that could become cancerous.//'It is very, very rare that a fibroid tumor could become cancerous,' said Dr. Nelson Teng, chief of gynecologic oncology at the Stanford University School of Medicine.Fibroids are benign growths in the uterus which sometimes cause discomfort,...Men who takes risk is unlikely to impress women
Men always have appreciated the value of taking risks as very macho and manly. A recent study in the journal// Evolution and Human Behavior had pointed out that although men who take risk get more friends, women do not like to have them as spouses. In the study carried out by the psychologists of University of Maine, males and females evaluated the attractiveness of risk takers as pote...An unlikely contender for speedy surgery recovery: Chewing gum
A rather unusual but very practical study was conducted in American hospitals and presented at the annual meeting of the American College of Surgeons in San Francisco reveals that those who chew gum after elective colon resection surgery recover sooner than those who do not//. The study involves 102 patients undergoing elective colon resection surgery. The patients were divided into t...New Gastric Cancer Drug Unlikely to Benefit Kidney Cancer Patients
An article appearing in the January issue of The Journal of Urology says that drugs used to treat gastrointestinal stromal cancers (GISTs) are likely to be ineffective for// patients with full blown kidney cancer. These findings are reported by investigators at the Mayo Clinic Cancer Center, who say that the drug in question is not going to help patients with high grade renal cell carc...Sharon Unlikely To Regain Consciousness
The doctors who are treating Israeli Prime Minister Ariel Sharon have declared that his condition is unlikely to improve from its vegetative state. // He is also not expected to regain consciousness. Ariel Sharon had suffered a brain hemorrhage, and he is still breathing with the help of a respirator. His condition however is reported to be stable. The Re'ut Rehabilitation Hospital’s...
