New study reports hotel guests at risk from carbon monoxide poisoning

...tabases and online news databanks, the researchers found 68 incidents of CO poisoning occurring at hotels, ...cted 43 sites where CO poisonings had occurred and found that only 12% had installed CO detectors after the incidents. In 101 sites where no CO poisoning had...

Crammed with charged DNA, pressure rises inside virus

...s negatively charged backbone must be overcome. We found that the positively charged ions in the solution are critical to overcoming this repulsion. Without the right combination of positively charged ions, the virus could not force all of its DNA into the capsid.” The researchers discovered that the fo...

Snoring in children might be an allergic type disease

The research found that snoring is in fact part of the spectrum of ch...5 years and respiratory function whilst awake were found to be unrelated. The study cohort was drawn from participants in the Australian Childhood Asthma ...

A new plant-bacterial symbiotic mechanism promising for crop applications

...her special form of symbiosis. These bacteria were found to have no nod genes, usually essential for nodulation. Bradyrhizobium consequently appeared to use mechanisms that involved other genes. This surprising result calls into question the universally recognized model of molecular communication that init...

Hormone helps mice 'hibernate,' survive starvation

...ular impact of PPAR-alpha in mice, the researchers found that it stimulates production of FGF21, a member of a hormone family that has been shown to lower blood glucose levels in diabetic and obese mice. FGF21, in turn, stimulates the use of stored fats as energy and causes torpor. In properly fed mice,...

Research team identifies new Alzheimer's gene

... it strikes” To date, the most significant gene found to predispose an individual to late onset Alzheimer’s (LOAD) has been APOE4. In this latest study, researchers from seven organizations contributed to the genome-wide scan using Affymetrix microarray technology. The team screened the DNA from 1,400 i...

Envisat captures first image of Sargassum from space

...ntribution to ocean productivity. "So far, we have found two things (Sargassum and Antarctic superblooms) that have never been seen from space before," said King. "It is really very exciting."...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...ch combines nucleotide base pairs in a way that is found in no other life form − into one that could be "...as well as other similar agents. Not all mutations found in all resistant isolates are the same, however. Parasites in different geographic regions have deve...

Loss of stem cells correlates with premature aging in animal study

...h Institute of the University of Pennsylvania have found that deleting a gene important in embryo development leads to premature aging and loss of stem cell reservoirs in adult mice. This gene, ATR, is essential for the body’s response to damaged DNA, and mutations in proteins in the DNA damage response un...

Pesticides choke pathway for nature to produce nitrogen for crops

...ointed to two published studies from 2000 that had found significant declines in both crop yield per unit of synthetic nitrogen fertilizer added and also a significant decline in overall symbiotic nitrogen fixation. The most common explanation for the observations is an overuse of agrichemicals applied ...

Despite some limitations, the study provides more evidence to support the use of phenobarbital in developing countries. The burden of un...

Columbine flowers develop long nectar spurs in response to pollinators

...by bumblebees, hummingbirds and hawkmoths. They found that most of the columbines' nectar spur length evolution happened during shifts in pollinators from bumblebees to hummingbirds, and from hummingbirds to hawkmoths. In between these shifts, evolution of the columbines' nectar spurs came to a halt. ...

Longer treatment benefits sleep apnea patients

... on average about 5 hours a night. The researchers found that although daytime sleepiness could be improved after 4 hours to 6 hours a night, depending on the measurement used, functional status or quality-of-life improvements were maximized after 7.5 hours of use each night. Although individual patient re...
