Switch that enables Salmonella to sabotage host cells revealed
- ScienceDaily
- 10/4/16 23:00
A new switch that enables Salmonella bacteria to sabotage host cells is revealed in a new study. Researchers say that the discovery could ultimately lead to drugs that interfere with the switch in order to combat Salmonella and possibly other bacterial infections. In humans, Salmonella causes diseases ranging from gastroenteritis to typhoid...

Banning trans fats from all foods in the UK would prevent thousands of heart attacks and deaths every year, and would be a simple way to protect the public and save lives, say two senior doctors.
Sierra Nevada yellow-legged frog's site fidelity may lead to further decline
- ScienceDaily
- 10/4/16 09:40
No longer found in 90 percent of its previously occupied habitat, the Sierra Nevada yellow-legged frog is further threatened by cumulative impacts of a changing climate, introduced non-native trout and site fidelity habits, hampering the breeding success of this imperiled frog. New research underscores the need to incorporate the site fidelity habits of this frog when designing restoration...
Slumber aids could improve intensive care outcomes

Eye masks and earplugs could help hospital patients get a better night's sleep. Researchers investigated their effect on sleep quality in a simulated intensive care environment.
Drug shared by addicts seems to protect against HIV brain dementia
- ScienceDaily
- 10/4/16 09:40
To their surprise, researchers have discovered that morphine (a derivate of the opium poppy that is similar to heroin) protects rat neurons against HIV toxicity -- a finding they say might help in the design of new neuroprotective therapies for patients with the infection.
Sequence is scaffold to study sleeping sickness
- ScienceDaily
- 10/4/16 09:40
Researchers have published the genome sequence for T. b. gambiense -- the strain of Trypanosoma brucei responsible for almost all cases of sleeping sickness in humans. A remarkable level of similarity with the previously sequenced bovine infecting strain suggests the sequences provide a foundation for studies into how these parasites cause disease. The team found no genetic cause for T. b....
Source of zodiac glow identified
- ScienceDaily
- 10/4/16 09:40
The eerie glow that straddles the night time zodiac in the eastern sky is no longer a mystery. First explained by Joshua Childrey in 1661 as sunlight scattered in our direction by dust particles in the solar system, the source of that dust was long debated. David Nesvorny and Peter Jenniskens put the stake in asteroids. More than 85 percent of the dust, they conclude, originated from Jupiter...
Breakthrough for babies born with severe cleft palates after experiments at ISIS
- ScienceDaily
- 10/4/16 09:40
Scientists working on a treatment for babies born with cleft palates have made a promising breakthrough and the first clinical trials are planned for early next year. Clefts are the most common birth defect in Britain, with one in every 700 babies affected; currently in severe cases radical surgery is required to correct the problem, and in addition future complications can occur as the child...

Personalized medicine for cancer patients in a new technology era
- ScienceDaily
- 10/4/16 09:40
A paper authored by over 200 members of the International Cancer Genome Consortium describes the beginnings of a Brave New World: a new era of personalized medicine for cancer patients. Formed in 2008, the consortium brings together leading cancer researchers from around the world, working together to catalog the genetic changes of the 50 most common cancers -- 500 genomes from each cancer type --...
Electronic 'nose' can predict pleasantness of novel odors
- ScienceDaily
- 10/4/16 09:40
Scientists have 'trained' an electronic system to be able to predict the pleasantness of novel odors, just like a human would perceive them. The researchers argue that the perception of an odor's pleasantness is innately hard-wired to its molecular structure, and it is only within specific contexts that personal or cultural differences are made...
Potential target for treatment of obesity-related diseases identified
- ScienceDaily
- 10/4/16 09:40
Scientists have identified a specific gene as potential new target for treating obesity-related diseases. Two recent research studies examined the role of a gene called STAT4 in the development of type 2 diabetes and other obesity-related cardiovascular diseases.
Scientists isolate portion of virus that causes pink eye
- ScienceDaily
- 10/4/16 09:40
Viral keratoconjunctivitis, also known as pink eye, is a common, uncomfortable and highly contagious condition. But now, relief may be in sight with a new understanding of how the eye reacts to this virus. Researchers used a novel model to determine what part of the virus is responsible for inflammation in pink...
Many patients don't know they had minor stroke, need emergency care
