Research into tobacco dependence has shown that recent ex-smokers who find exposure to other people's cigarette smoke pleasant are not any more likely to relapse than those who find it unpleasant.

The first reports of the successful reprogramming of adult human cells back into so-called induced pluripotent stem cells, which by all appearances looked and acted liked embryonic stem cells created a media stir. But the process was woefully inefficient: only one out of 10,000 cells could be persuaded to turn back the clock. Now researchers successfully reprogram keratinocytes attached to a...
In the quest to discover the root of illnesses, patients have to undergo an increasing number of scans and tests that may involve the use of ionising radiation to detect the source and scope of an ailment. However, this practice could also put patients at risk.
Researchers have discovered that when the leaf of a plant is under attack by a pathogen, it can send out an S.O.S. to the roots for help, and the roots will respond by secreting an acid that brings beneficial bacteria to the rescue.
A study of residential patterns in America suggests that White and Black Hispanics born in the US are more likely to share neighborhoods with native non-Hispanic Whites and African Americans, compared to foreign-born Hispanics -- a pattern consistent with immigrant assimilation. Hispanics from Mexico in particular integrate consistently with all ethnic groups over...
A new study sheds light on the lives of teenage boys who abuse their girlfriends.
It is not uncommon for a few boxes of valuable goods to disappear from palettes on the way to retail outlets. That is why researchers in Germany are working on a new technical platform to safeguard such items. This involves using wireless ad-hoc sensor networks to create logistical information systems that allow them to be tracked along the entire distribution...
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species.
Asthma sufferers who regularly take the beta2-agonist formoterol are more likely to suffer non-fatal serious adverse events than those given placebos. A review carried out by Cochrane researchers showed a significantly increased risk for people who took the drug once or twice daily for at least 12 weeks.
In virtually all stores, consumers view products on display fixtures that are presumed to be of little consequence. Yet, suppose that you were shopping for a set of trendy new coffee mugs and noticed some on a nearby table or shelf. Would your evaluation of just how trendy the mugs are change depending on the display fixture's surface material -- the piece of glass or wood beneath the product?...
A Brazilian palm berry, popular health food though little research has been done on it, now may have its purported benefits better understood. In the first research involving people, the acai berry has proven its ability to be absorbed in the human body when consumed both as juice and pulp.
Researchers have developed a low-cost, high-resolution imaging system that can be attached to a helicopter to create a complete and detailed picture of an area devastated by a hurricane or other natural disaster. The resulting visual information can be used to estimate the number of storm refugees and assess the need for health and humanitarian...
A young child arrives at the emergency room after several days of abdominal pain, vomiting, and diarrhea and is sent home with a diagnosis of viral gastritis and treatment for the symptoms. The child seems better for a while, only to return to the ER with worse symptoms and a ruptured appendix, a life-threatening complication of...
A majority of Parkinson's patients in a clinical study had insufficient levels of vitamin D, significantly more than Alzheimer's patients or healthy elderly people. The finding suggests that lack of vitamin D may contribute to the risk of developing Parkinson's.
A protein that enables nerve cells to communicate with each other plays a key role in controlling the developing nervous system. Research into how that protein helps precise connections to form among nerve cells may provide a basis for eventual treatments for patients who suffer injuries to their nervous system, including spinal cord...
Two new articles examine the theory of "fetal programming" and their effect on racial health disparities. The studies, published in American Journal of Human Biology, suggest that the higher rates of hypertension and cardiovascular disease present in African Americans may be a consequence of low birth weights, and that these low birth weights may be a result of social rather than genetic...
Use of the influenza vaccine was not associated with preventing hospitalizations or reducing physician visits for the flu in children age 5 and younger during two recent seasons, perhaps because the strains of virus in the vaccine did not match circulating strains, according to new report.
Genetically modifying a receptor found on the neurons that produce the neurotransmitter dopamine has given researchers a unique glimpse into the workings of the brain's dopamine system -- as well as a new target for treating diseases that result from either too much or too little of this critical...
Sleep in humans is divided in two main phases: non-REM sleep, which occupies most of our early sleep night, and REM sleep, during which our dreams prevail. Non-REM sleep is usually considered as a compensatory 'resting' state for the brain, following the intense waking brain activity. Now, new research challenges previous brain imaging studies which showed that the brain was less active during...
Serious challenges remain in radioactivity readiness, according to a new study that finds emergency room doctors and nurses worry that hospitals are not adequately prepared to handle casualties from a radioactive 'dirty bomb.' Among the concerns is whether ER staffers, in a dirty bomb scenario, could protect themselves and give appropriate care, the study authors...
Like a burning fire, the brain is in constant need of oxygen, and when a blood vessel is blocked during a stroke, part of the brain becomes starved of oxygen and nutrients. When this happens, neurons in that part of the brain die off, leading to permanent loss of function in the parts of the body those neurons...
A new study reveals that specific types of bacteria in the intestine trigger the generation of pro-inflammatory immune cells, a finding that could eventually lead to novel treatments for inflammatory bowel disease and other diseases.
Four months after a successful hand transplant -- 35 years after amputation in an industrial accident at age 19 -- a 54-year-old man's emerging sense of touch is registered in the former "hand area" of the his brain, says a University of Oregon neuroscientist.
College students often spend their free time thinking about beer, but a group of Rice University students are taking it to the next level. They're using genetic engineering to create beer that contains resveratrol, a chemical in wine that's been shown to reduce cancer and heart disease in lab animals.
A new study shows that men are more likely to lose vision as a result of a particular cause of intracranial hypertension, or increased pressure in the brain, than women with the condition.
