We know that individuals who smoke take major health risks. Now a new research study from Lund University in Sweden shows that common treatment for breast cancer works less well in patients who smoke, compared to non-smokers.

The study is published in the British Journal of Cancer.

The well-known hormone melatonin is not just promoting sleep in humans and animals but is also involved in stress tolerance in plants.

And Crop Physiologists from the Department of Plant and Environmental Sciences at the University of Copenhagen has now documented the roles of melatonin in drought priming and stress memory in barley, together with The University of Texas Health Science Center at San Antonio, USA.

Warsaw, Poland, 17 June 2016 - A new study from the UK Centre for Substance Use Research, being presented today at the Global Forum on Nicotine, shows e-cigarettes are playing an important role in reducing the likelihood of young people smoking, in many cases acting as a 'roadblock' to combustible tobacco.

In detailed qualitative interviews with young people aged 16 to 25 across Scotland and England, the majority of participants viewed e-cigarettes as having reduced - not increased - the possibility of both themselves and other people smoking.

The recently recognised global distribution of the mcr-1 gene poses a substantial public health risk to the EU/EEA. The gene is widespread in several continents and has been detected in bacteria isolated from multiple different sources such as food-producing animals, food, the environment and humans.

Daejeon, Republic of Korea, June 17, 2016--Clostridium tyrobutyricum, a Gram-positive, anaerobic spore-forming bacterium, is considered a promising industrial host strain for the production of various chemicals including butyric acid which has many applications in different industries such as a precursor to biofuels. Despite such potential, C. tyrobutyricum has received little attention, mainly due to a limited understanding of its genotypic and metabolic characteristics at the genome level.

Scientists potentially have found a way to disrupt Zika and similar viruses from spreading in the body.

A team at Washington University School of Medicine in St. Louis has identified a single gene pathway that is vital for Zika and other flaviviruses to spread infection between cells. Further, they showed that shutting down a single gene in this pathway -- in both human and insect cells -- does not negatively affect the cells themselves and renders flaviviruses unable to leave the infected cell, curbing the spread of infection.

Here's another reason why you should hit the gym regularly as you grow older: A new report appearing online in The FASEB Journal shows that regular exercise plays a critical role in helping muscles repair themselves as quickly as possible after injury. For many mammals, including humans, the speed of muscle repair slows as they grow older, and it was once thought that complete repair could not be achieved after a certain age.

Low levels of BPA exposure may be considered safe, but new research published online in The FASEB Journal, suggests otherwise. In the report, researchers from Yale show that the genome is permanently altered in the uterus of mice that had been exposed to BPA during their fetal development.

TORONTO, ON - A University of Toronto-led team has reported the discovery of a new lizard in the middle of the most- visited island in the Caribbean, strengthening a long-held theory that communities of lizards can evolve almost identically on separate islands.

The chameleon-like lizard - a Greater Antillean anole dubbed Anolis landestoyi for the naturalist who first spotted and photographed it - is one of the first new anole species found in the Dominican Republic in decades.

An extremely rare eyeless catfish species previously known to exist only in Mexico has been discovered in Texas.

Dean Hendrickson, curator of ichthyology at The University of Texas at Austin, identified the live fish, discovered in a deep limestone cave at Amistad National Recreation Area near Del Rio, Texas, as the endangered Mexican blindcat (Prietella phreatophila). The pair of small catfish, collected by a team in May, have been relocated to the San Antonio Zoo.

ARLINGTON, Texas -- Though much progress has been made toward gender equality, news coverage of female politicians typically follows gendered lines that often disregards women's competence in political affairs, a University of Texas at Arlington assistant communication professor has found.

Dustin Harp, an expert in gender and media studies, examines the issue in "Hillary Clinton's Benghazi Hearing Coverage: Political Competence, Authenticity, and the Persistence of the Double Bind," which appears online in the June issue of Women's Studies in Communication.

Black children who undergo urologic surgery are more likely than white children to have postsurgical complications and hospital-acquired infections 30 days after the surgery. Researchers studying a national database from over 50 U.S. pediatric hospitals suggest that hospitals and policy makers should expand efforts to reduce postoperative adverse events and health disparities in children.

The body's defences detect and eliminate not only pathogens but also tumour cells. Natural killer cells (NK-Cells) are specifically activated by chemical messengers, the Cytokines, to seek and destroy tumour cells. Veronika Sexl and her team from the Institute of Pharmacology and Toxicology at the Vetmeduni Vienna study the fundamentals of tumour surveillance by the immune system in animal models.

Birth by C-section, exposure to antibiotics and formula feeding slow the development and decrease the diversity of a baby's microbes through the first year of life. That is the finding of a study led by researchers from NYU Langone Medical Center and published June 15 in the journal Science Translational Medicine.

Although red-eyed treefrog embryos appear helpless within their jelly-coated eggs, they can hatch up to two days ahead of schedule, reacting within seconds to attacks by egg thieves. At the Smithsonian Tropical Research Institute (STRI) in Panama, scientists used high-speed video to uncover their rapid-hatching secret.
