More Nutritional Cassava (Yucca) For Developing World

An intensive international effort to improve the nutritional value of cassava -- a staple food for millions of poverty stricken people in sub-Sahara Africa and other areas -- has led to development of a New form of cassava that may be easier to digest than other varieties. Also known as yucca or manioc, the roots of the plant are similar to potatoes and are often eaten boiled or deep fried.

Practice-based Intervention Has Sustained Benefits For Children And Families

The Healthy Steps for Young Children Program, which added behavior and development services to pediatric practices, continued to benefit families more than two years after the intervention ended. The sustained benefits from participation included greater satisfaction among parents with their child's health care, greater odds that parent's will report a child's serious behavioral issue to the...

'Fruity Vegetables' And Fish Reduce Asthma And Allergies

Giving children a diet rich in fish and "fruity vegetables" can reduce asthma and allergies, according to a seven-year study of 460 children. The findings also reinforce the researchers' earlier findings that a fish-rich diet in pregnancy can help to protect children from asthma and allergies.

A Child's IQ Could Be Affected By Maternal Epilepsy

A history of maternal epilepsy and its associated treatment may be linked to impaired intelligence later in life, says a new study.Researchers investigated the IQ levels of sons born to mothers with and without epilepsy, and found a correlation between intelligence and the illness.

Alex, The Renowned African Grey Parrot, Dies At 31

Alex, the world renowned African Grey parrot made famous by the ground-breaking cognition and communication research conducted by Brandeis scientist Irene Pepperberg, Ph.D., died at the age of 31 on September 6, 2007. Alex learned elements of English speech to identify 50 different objects, 7 colors, 5 shapes, quantities up to and including 6 and a zero-like concept. He used phrases such as "I...

Brain Network Related To Intelligence Identified

Researchers have uncovered evidence of a distinct neurobiology of human intelligence. This Parieto-Frontal Integration Theory identifies a network related to intelligence, one primarily involving areas in the frontal and the parietal lobes. The data suggest that some of the brain areas related to intelligence are the same areas related to attention, memory and language. This possible integration...

Cluster And Double Star Uncover More On Bright Aurorae

Cluster data has helped provide scientists with a new view of magnetospheric processes, challenging existing theories about magnetic substorms that cause aurorae and perturbations in GPS signals. The onset of magnetic substorms that originate in Earth’s magnetosphere has been explained by two competing models: current disruption and near-earth reconnection. Current beliefs have been...

Diesel Exhaust Kills Throat Cells, Study Shows

Diesel exhaust is far more damaging to our health than exhaust from biodiesel, the plant-based fuel, according to a new study. As it is not possible to study in real time what happens in the real human airway, the researchers conducted their research on human airway cells grown in a culture. The cells were exposed to the particulate matter emitted in diesel and biodiesel exhaust fumes.

Drug Spending Caps Cause Some Seniors To Quit Taking Key Medicines

Many seniors quit taking drugs for chronic illnesses such as diabetes and high blood pressure when they exceed their drug plan's yearly spending limits, according to a new study. The report, which examines the behavior of seniors enrolled in a private health plan, provides insight into how seniors may act under provisions of Medicare's new drug benefit plan that will leave about one-third of...

Ethical Issues Of Scientific Research In Developing World Examined

The first comprehensive examination of the ethical, social and cultural (ESC) challenges faced by major science programs in developing countries has identified a complex assortment of issues with the potential to slow critical global health research if left unaddressed. They range from problems such as government corruption to complex questions surrounding community and public engagement, cultural...

Gay Or Straight? Body Type And Motion Reveals Sexual Orientation, Study Suggests

An individual's body motion and body type can offer subtle cues about their sexual orientation, but casual observers seem better able to read those cues in gay men than in lesbians, according to a new study. Based on measurements, the researchers determined that the gay subjects tended to have more gender-incongruent body types than their straight counterparts (hourglass figures for men, tubular...

Glaucoma Surgery In The Blink Of An Eye

Scientists are testing a new laser surgery device specifically designed to make glaucoma procedures safer, simpler and faster. The revolutionary non-penetrating technique will be easily mastered by most eye surgeons, thereby making it more accessible and less risky for glaucoma sufferers. Glaucoma is the second leading cause of blindness in the West.

Health Food Supplement May Curb Addiction Of Pathological Gamblers

Researchers have discovered that a common amino acid, available as a health food supplement, may help curb pathological gamblers' addiction. Results are encouraging for other addictions, too. In a recent eight-week trial, 27 people were given increasing doses of a specific amino acid which has an impact on the chemical glutamate -- often associated with reward in the brain. At the end of the...

New Approach To Fighting Obesity And Diabetes: Analyze Starches

World-first equipment will determine how to produce food which is better for us, but still tastes good. The researchers said that while an unhealthy lifestyle and poor eating habits were significant factors in Australia's obesity and diabetes epidemics, they were not entirely to blame. Another component is changes in starches in our food.

New Clues To Breast Cancer Development In High-risk Women

Physicians who treat women with the breast cancer susceptibility gene BRCA1 often remove their patients' ovaries to eliminate the source of estrogen they believe fuels cancer growth. Yet they also know that anti-estrogen therapies don't work to treat breast or ovarian cancer that might develop. That paradox has led scientists to question exactly how, or if, estrogen is involved in cancer...

Prescription Labels Geared Toward Pharmacies, Not Patients

The labels on most prescription drug containers highlight the pharmacy's name or logo rather than instructions on how to take the medication, reports a new study. All of the labels listed the pharmacy name first, and instructions appeared fifth on 89 percent of labels. When color font or boldface was present, it was most often for pharmacy information rather than for instructions or warnings.

Primate Behavior Explained By Computer 'Agents'

The complex behavior of primates can be understood using artificially-intelligent computer "agents" that mimic their actions, shows new research. Scientists using agents programmed with simple instructions to work out why some primate groups are 'despotic' whilst others are 'egalitarian' - overturning previous theories developed by primatologists.

Rare Dolphin Driven To Extinction By Human Activities, Scientists Fear

An international research team, including biologists from NOAA Fisheries Service has failed to find a single Yangtze River dolphin, or baiji, during a six-week survey in China. The scientists fear the marine mammal is now extinct due to fishing and commercial development, which would make it the first cetacean to vanish as result of human activity.

Transforming Mouse Cells Into 'Embryonic' Stem Cells Easily

Scientists are reporting what they say is a significant improvement in the technique for genetically reprogramming mouse cells to their embryonic state, a process that transforms the cells, in essence, into embryonic stem cells. Scientists are interested in reprogramming because of its potential for developing human embryonic stem cells that contain the genetic makeup of individual patients. In...
