Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
RICHLAND, Wash. - Like the poet, microbes that make methane are taking chemists on a road less traveled: Of two competing ideas for how microbes make the main component of natural gas, the winning chemical reaction involves a molecule less favored by previous research, something called a methyl radical.
Reported today in the journal Science, the work is important for understanding not only how methane is made, but also how to make things from it.
Climate scientists have long recognized the importance of forest conservation and forest regrowth in climate mitigation and carbon sequestration -- capturing carbon dioxide (CO2) from the atmosphere. But the detailed information required to make accurate estimates of this potential has remained elusive.
Now, an international team of 60 scientists, working together as the 2ndFOR Network, has completed studies on the effects of forest conservation and secondary forest regeneration across 43 regions in Latin America.
Why does delaying bedtime create chronic sleepiness?
We may be creeping a little closer to knowing, thanks to a paper on fruit flies in Cell. Fruit flies have sleep remarkably similar to people and researchers say they found a group of brain cells in charge of so-called sleep drive that becomes more active the longer flies are kept awake. The same mechanism, they say, also plays a role in putting the flies to sleep and keeping them that way.
EAST LANSING, Mich. -- People with intellectual disabilities are more susceptible to exploitation and abuse, and the rise of the Internet only increases their vulnerability.
A first-of-its-kind study co-authored by a Michigan State University scholar finds that adults with Williams syndrome -- who are extremely social and trusting -- use Facebook and other social networking sites frequently and are especially vulnerable to online victimization.
Roughly a third of study participants said they would send their photo to an unknown person, arrange to go to the home of a person they met online and keep online relationships from their parents.
Professional athletes suffer from sleep disorders more frequently than generally thought, however, systematic examination, counselling and individual treatment planning can improve the quality of their sleep. Published in the Journal of Sports Sciences, a new Finnish study clearly shows for the first time that systematic measures can improve the sleep of professional athletes.
The results of a new survey published in ecancermedicalscience indicate that a majority of oncology professionals believe that writing condolence letters to the families of deceased patients is an important component of cancer palliative care.
The study explored whether institutions should consider changing policies to raise condolence letters to a more official standing.
But because this practice is a personal grace note, it has rarely been studied or discussed. In particular, this issue hasn't been researched in the UK, where cultural practices surrounding grief are often private.
Amsterdam, May 19, 2016 -- Dirty laundry smells bad because of certain chemicals called volatile organic compounds, which can't always be washed out on an eco-friendly 20?C cycle, according to a new study in the Journal of Chromatography A.
Consumers' awareness of the ecological impacts of washing - the temperature of the wash and the detergent they use - is increasing, so it is important to understand why dirty clothes smell, in order to find the best way to clean them. The researchers behind the new study, from Northumbria University, say the chemicals they identified could be used to test the effectiveness of washing at different temperatures.
Neuherberg, May 19, 2016. One year after the introduction of the Bavarian pilot project Fr1da, the Institute of Diabetes Research, Helmholtz Zentrum München has published the first results in the BMJ Open journal. None of the 105 children who have been diagnosed with An early stage of type 1 diabetes have suffered from metabolic imbalance so far.
A new USC-led study identified a "sunscreen" gene that may help stave off skin cancer.
The researchers found that the "UV radiation Resistance Associated Gene" is a tumor suppressor for skin cancer, which is the most common form of cancer in the United States. Melanoma is the deadliest skin cancer. In fact, melanoma rates have doubled over the last three decades, according to the Centers for Disease Control and Prevention.
A large proportion of cancer cases and deaths among U.S. individuals who are white might be prevented if people quit smoking, avoided heavy drinking, maintained a BMI between 18.5 and 27.5, and got moderate weekly exercise for at least 150 minutes or vigorous exercise for at least 75 minutes, according to a new study published online by JAMA Oncology.
Cancer is a leading cause of death in the United States.
Stem cells are typically thought to have the intrinsic ability to generate or replace specialized cells. However, a team of biologists at NYU showed that regenerating plants can naturally reconstitute their stem cells from more mature cells by replaying embryogenesis.
"Paradoxically, this means that, in this system, stem cells don't immediately generate the plant's tissue, but, rather, tissues make stem cells," explains Kenneth Birnbaum, an associate professor in New York University's Department of Biology and the study's senior author.
