Smoking tobacco from a waterpipe, also known as a hookah, accounted for over half of the tobacco smoke volume consumed by young adult hookah and cigarette smokers in the U.S.
As “mega-fires” in the boreal forest become more frequent and more intense, scientists believe the burning of these carbon-rich areas will drastically increase the amount of carbon being released into the atmosphere. But because these mega-fire areas are so large—more than 10,000 hectares (25,000 acres)—and are home to a complex diversity of vegetation types, accurately predicting these emissions has been challenging. A study recently completed by a team of NAU scientists was designed to help solve this problem.
FINDINGS UCLA-led research suggests that receiving support from friends and acquaintances can help prevent black men who have sex with men from becoming infected with HIV. BACKGROUND Black men who have sex with men have disproportionately high rates of HIV infection. While social connections are known to influence the behaviors that influence people’s risk for HIV, little is known about whether they affect the risk for becoming infected with HIV.
A new study from a research team from the Georgia Institute of Technology found that the vast majority of scientists disclose key details about their work informally to peers and potential collaborators ahead of publishing in a peer reviewed journal or presenting the findings publicly.
Given the complex and rapidly evolving health care system in the United States, medical schools must focus their efforts on training more physician leaders to master the diverse skills needed to navigate emerging challenges in the field, urge leaders from the Perelman School of Medicine at the University of Pennsylvania in a new Perspective piece published today in the New England Journal of Medicine.
People with mild asthma are often prescribed a daily treatment regimen, but up to 80 per cent do not follow the routine, using inhalers only when they have an asthma attack. Now the researchers have found an as-needed combined-drug inhaler is a viable treatment option.

A new study by researchers from the University of Chicago Medicine shows that bacterial signals are crucial to the development of a precursor condition to leukemia, which can be induced by disrupting the intestinal barrier or by introducing a bacterial infection.
Scientists have understood little about how chikungunya and related viruses cause arthritis. Now, researchers at Washington University School of Medicine in St. Louis have identified the molecular handle that chikungunya grabs to get inside cells. The findings, published May 16 in the journal Nature, could lead to ways to prevent or treat disease caused by chikungunya and related viruses.
Los investigadores de Mayo Clinic descubrieron que una vía de comunicación molecular, sobre la cual se creía que era defectuosa en el cáncer, desempeña un papel fundamental para determinar la eficacia del tratamiento con el virus del sarampión oncolítico en el cáncer de ovario y otros cánceres agresivos del cerebro.
Contrary to previous analyses, research published by Michigan State University shows that projected changes in temperature and humidity will not lead to greater water use in corn. This means that while changes in temperatures and humidity trend as they have in the past 50 years, crop yields can not only survive – but thrive.
Researchers from Case Western Reserve University School of Medicine have discovered how unusually long strands of RNA help colon cancer cells avoid death, allowing unregulated growth. Unlike other RNAs, the intriguing strands do not appear to encode proteins and are termed “long non-coding RNAs” or “lincRNAs.”A new study showed some lincRNAs could be targeted by drug developers to halt colon cancer.
Mayo Clinic researchers have discovered that a molecular communication pathway – thought to be defective in cancer – is a key player in determining the effectiveness of measles virus oncolytic cancer treatment in ovarian and aggressive brain cancers. This discovery enabled researchers to develop an algorithm to predict treatment effectiveness in individual patients. The findings appear in the Journal of the National Cancer Institute.
Researchers have probed the movements of molecules in liquid water that occur in less than 100 millionths of a billionth of a second, or femtoseconds.
In Texas, the Southern High Plains uses water from an aquifer to water cotton fields. However, the aquifer is running low. Scientists from the area are working to find the best irrigation method for cotton that uses the least water.
UPTON, NY—Do you know someone who’s so caught up in the details of a problem that they “can’t see the forest for the trees?” Scientists seeking to understand how forests recover from wildfires sometimes have the opposite problem. Conventional satellite systems that survey vast tracts of land burned by forest fires provide useful, general information, but can gloss over important details and lead scientists to conclude that a forest has recovered when it’s still in the early stages of recovery.
About 22 million Americans are substance dependent, yet only 2.5 million seek treatment. Reviewing 5,443 records of adult substance use treatment clients, a new study examined treatment readiness, or the characteristics that are likely to promote treatment engagement, to predict who seeks and stays in treatment. Results show that white and black race, being male, lower levels of education, and being married or divorced (vs. never married) were all negatively related to substance-use treatment engagement.

Many studies have shown that both minority and women scientists face disadvantages in reaching the highest levels of their careers. So it would make sense that minority women would face a “double bind” that would particularly disadvantage them. But a new study suggests that minority women actually face a “one-and-a-half bind."
The study – to be published in the June edition of the Journal of the American Medical Association Psychiatry – found that measuring electrical activity in the brain can help predict a patient’s response to an antidepressant.
