Newborn screening can cause unnecessary parental stress

...as more disorders are added to the screening ?many states now test for 30 or more ?false-positive results are on the rise. In the June issue of Pediatrics, researchers from Children's Hospital Boston report that false-positive results cause considerable parental stress, even when the baby proves negative on...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...effects of psychoactive drugs, that detect altered states of consciousness, that rate mystical experiences and assess changes in outlook. The study, Griffiths adds, has advanced understanding of hallucinogen abuse. As for where the work could lead, the team is planning a trial of patients suffering...

Ecosystem services and invasive species

...s in our own backyards. Tennessee and neighboring states contain the world's richest diversity of freshwater mussels. How can we start to protect these mussels, if we don't even know what's in our local rivers?," says Kesler. ...

Wild vs. lab rodent comparison supports hygiene hypothesis

...oimmune disease is the "hygiene hypothesis," which states that people in "hygienic" societies have higher rates of allergy and perhaps autoimmune disease because they -- and hence their immune systems -- have not been as challenged during everyday life by the host of microbes commonly found in the environme...

UN review shows need to halt destructive fishing practice

...Assembly in 2004, was based on reports from member states on steps taken to stop destructive high seas fishing practices. A draft version of the review posted July 14 on the DOALOS Web site said extremely vulnerable deep sea habitats require protection, but that fishing for newly discovered resources in t...

How satellite tracking revealed the migratory mysteries of endangered Atlantic loggerhead turtles

... international cooperative effort in seven African states is needed to create a strategy that would protect them." Research* shows that in 2000 1.4 billion hooks were cast into the world's oceans through industrial fishing. It's thought that globally more than 200,000 loggerhead turtles were incidentally c...

First 'encyclopedia' of nuclear receptors reveals organisms' focus on sex, food

...ors form networks and interact to regulate disease states and physiology in two main areas, reproduction and...rs might help explain aspects of the out-of-rhythm states linked to many metabolic diseases," Dr. Mangelsdorf said. Researchers detailed all receptor expres...

Survival of the selfless - scientists find cheats don't always prosper

...his contradicts classic evolutionary theory, which states that in a competition for common resources the long-term winner will always be the individual acting selfishly rather than the one working as part of a group. To test this theory, scientists set up a series of competitions between two strains of yea...

Bacteria beat the heat

...s heated up. A general rule for enzyme reactions states that as the heat rises, so does the reaction rate. Contrary to this rule, and the scientist's expectations, both reaction rates peaked at a certain point, and remained steady thereafter. For each enzyme, the peak occurred in the bacteria's "comfort z...

Researchers map out networks that determine cell fate

... of stem cells, then resolving these mixed-lineage states will invariably involve counteracting repressors." In collaboration with colleague Aaron Dinner, the research team also formulated a mathematical model that depicts the regulatory network governing progenitor cell development. This model, he said, c...

In a technical tour de force, Salk scientists take a global view of the epigenome

...s aren't during different developmental or disease states might show how cells self-renew or growth control genes become de-regulated. The investigators also found that methylation silences transposons, so-called "jumping genes," which can wreak genomic havoc by hopping about the chromosomes. In the words...

Better beetle sought for salt cedar control

...rney said. "Because some of the releases in other states haven't been successful,we're starting to think it may be more complicated than that," she said."These beetles from Uzbekistan seem to be most suited to our climate atthe same latitude and longitude." At the Meredith site, the Posidi beetles release...

Even fish don't swim well when they're young!

...over into the coast phase, while the latter theory states that when the larvae are very small they experience the water in a different way; it appears thicker, like syrup and harder to swim in. "Momentum can explain some of the poor swimming in larvae, but not all, and the difference in coasting ability can...

Researchers win money to develop breath test to detect breast cancer

... technology into applications. The IDEA proposal states that the switchable surfaces have molecularly designed sites that will attract certain metabolites indicative of breast cancer. These sites are actually little nanopockets about 6.4 nm2 in size, that interact with oil and water. The metabolites are a...

'Scent of a woman' tells male redback spiders to find a mate

...s] in the wild," says Kasumovic. "Everybody always states that the small males are a by-product of them not being able to get enough resources, but we're showing that they're intentionally developing that way." ...

Man-made heart tissue improves cardiac performance

...s to generate functional cardiac muscle in vitro," states lead researcher, Ravi K. Birla. "Work in this area would lead to the formation of functional heart muscle that can someday help patients with acute heart failure." Tissue-engineered heart muscle can be used to treat cases of myocardial infarcti...

'Biobullets' fight harmful mussels

...ussels have rapidly spread and are now found in 21 states including Oklahoma, Louisiana and Vermont, according to the USGS. Unchecked, many scientists suspect zebra mussels will soon spread throughout North American waterways. ...

ASU researchers find link between social behavior, maternal traits in bees

...sponsible for reproduction, the ancestral foraging states were no longer linked to reproductive activity in worker bees, predicted Amdam. But the states could still influence foraging behavior, resulting in a division of labor between pollen-foraging an...

Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

...hat correlates aspects of spirituality and altered states of consciousness, and the other is the Tridimensional Personality Questionnaire (TPQ), a measure of the need for social contact and openness to communication. The genetic and questionnaire results of the dancers were compared with those of two othe...
