Mold Linked To Asthma

A new study has found that removing indoor mold improves the symptoms of people with asthma. Asthma UK figures show the prevalence of asthma in Wales is among the highest in the world, with 260,000 people receiving treatment for their asthma with the rate of hospital admissions for adults 12 percent more than anywhere else in the UK.

Mouse Model For Schizophrenia Has Genetic On-off Switch

The researchers developed the transgenic mouse by inserting the gene for mutant Disrupted-In-Schizophrenia-1 (DISC-1) into a normal mouse, along with a promoter that enables the gene to be switched on or off. Mutant DISC-1 was previously identified in a Scottish family with a strong history of schizophrenia and related mental disorders.

Screening Family Members Could Prevent 4 In 10 Premature Heart Attacks

Screening and treating middle-aged adults with a family history of coronary heart disease (CHD) could prevent more than 4 in 10 premature heart attacks, according to a recent article. Family history, the researchers say, can identify a large proportion of people at high overall risk of developing CHD. They point to one study which found that the 14% of families with a positive family history...

Gray Whales A Fraction Of Historic Levels, Genetic Research Says

Gray whales in the Pacific Ocean, long thought to have fully recovered from whaling, were once three to five times as plentiful as they are now, according to a new article. A vastly reduced population of gray whales has likely exerted large changes in Pacific ocean ecosystems. Starving whales are a warning sign of problems in the food chain.

Liberals More Likely Than Conservatives To Break From Habitual Responses, Study Finds

Liberals are more likely than are conservatives to respond to cues signaling the need to change habitual responses, according to a new study by researchers at New York University and UCLA. The findings, which show that self-rated liberalism is associated with the type of brain activity involved in regulating conflict between a habitual tendency and an alternative response, appear in the online...

Mediterranean Diet May Help Alzheimer's Patients Live Longer

A Mediterranean diet may help people with Alzheimer's disease live longer than patients who eat a more traditional Western diet. The study followed 192 people with Alzheimer's disease for an average of four and a half years. During that time, 85 of the people died. Researchers found that those who most closely followed a Mediterranean diet were 76 percent less likely to die during the study period...

Recognition, Identification And Tracking Systems Under Development To Assist Air Force

The development of fast and accurate computer algorithms for the automated recognition, identification, classification and tracking of targets of interest is underway. It is expected to have many applications such as chemical agent monitoring, weather and hurricanes tracking and monitoring and explosive detection at the battlefield. The project also aims to develop unmanned air vehicle sensor...

Why Genes Of One Parent Are Expressed Over Genes Of The Other: New Ideas In Genomic Imprinting

How we come to express the genes of one parent over the other is now better understood and it doesn't seem to have originated in association with sex chromosomes. New research has shed light on the evolution of genomic imprinting, in which specific genes on chromosomes that have been inherited from one parent are expressed in an organism, while the same genes on the chromosome inherited from the...

Elevated Blood Pressure In Youth Linked To Rise In Childhood Obesity

After decades of decline, blood pressure levels in children and adolescents are increasing. Researchers said that each one centimeter increase in waist circumference raised the likelihood of high blood pressure by 10 percent and the likelihood of pre-high blood pressure by five percent. High blood pressure is a major public health problem in adults and a common risk factor for heart attack and...

Gene Expression May Be Altered In Drug Addiction: Mechanism Illuminated

Scientists recently completed a study investigating one of the changes in gene expression that occurs when individuals take addictive drugs. The studies focus on how the primary RNA transcript is processed by splicing to produce a mature transcript. The fidelity of splicing must be maintained since errors may lead to the development of disease.

Implantable Device Designed To Detect, Stop Seizures Under Study

A small device implanted in the skull that detects oncoming seizures, then delivers a brief electrical stimulus to the brain to stop them is under study. Participants have a device implanted in the skull, with up to two wires containing electrodes placed near the seizure focus. A modified laptop computer looks at electrical activity picked up by the neurostimulator, then is used to program the...

Reading Process Is Surprisingly Different That Previously Thought, Technology Shows

Being able to read competently is one of the most important skills we need to function in today's fast-paced society. Analysing the way we read can offer valuable insights into how we process visual information. Scientists have been interested in the movements of our eyes while reading for forty years. However, until now most assumed that when we read both eyes look at the same letter of a word...

Mathematics Of Ice To Aid Global Warming Forecasts

Mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice -- a discovery that promises to improve forecasts of how global warming will affect polar icepacks. Researchers show that brine moving up or down through floating sea ice follows "universal transport properties."

Physics Reveals The Secrets Of Saint Francis

The tunic believed to have been worn by Saint Francis of Assisi preserved in the Church of Saint Francis in Cortona (Province of Arezzo) dates back to the period in which the saint lived, whereas the tunic preserved in the Church of Santa Croce in Florence was made after his death. Carbon 14 measurements, which allow a relic to be dated, show that the tunic in Santa Croce dates back to some time...

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...
