Researcher hunts DNA on Mars

Astrobiologist alumna Alexandra Pontefract, PhD'13 (Geology), knows finding DNA on the Red Planet will be no easy feat. But it is possible. What's more, if DNA is found, it's not far-fetched to think it would be proof of shared ancestry between Earth and Mars.

How old is our moon?

Most scientists agree that the Earth has pretty much always had its moon. Details of the moon's composition (in particular the "isotopic mixture" of heavier and lighter versions of various elements) are too similar to the Earth's for it to have been captured from somewhere remote. However, some compositional details differ enough to rule out the idea that the moon is simply a chunk of the Earth that broke loose.

Children gain more weight when parents see them as 'overweight'

Children whose parents considered them to be 'overweight' tended to gain more weight over the following decade compared with children whose parents thought they were a 'normal' weight, according to analyses of data from two nationally representative studies published in Psychological Science, a journal of the Association for Psychological Science. The findings indicate that children whose parents identified them as being overweight perceived their own body size more negatively and were more likely to attempt to lose weight, factors that partly accounted for their weight gain.

Sunbed users get melanoma at a younger age

Melanoma is the most dangerous type of skin cancer with the strongest increase in incidence in the last decade, and the incidence rates have never been as high as in 2014 (www.kreftregisteret.no). Now there are about 2,000 new cases of melanoma each year in Norway. The World Health Organization based International Agency for Research on Cancer has classified UV-emitting tanning devices as "carcinogenic to humans" in 2009 (www.iarc.fr). However, sunbed use is still popular in western countries, especially among young women.

Increased cooperation between preschool and CHC to identify children with mental health problems

It is beneficial to systematise the exchange of information between parents, preschool and child care centres (CHCs) to increase the focus on young children with mental health problems. This is shown in a recently conducted study from Uppsala University, published in the journal PLOS One.

Sensory stimuli control dopamine in the brain

Regardless of whether we are sitting in a loud aeroplane or walking through a quiet forest clearing, how humans perceive their environment depends on the stimuli. This, in turn, affects our behaviour – sometimes consciously, sometimes subconsciously. In their study of fish larvae, Prof. Dr. Wolfgang Driever and his team of neurobiologists at the University of Freiburg have discovered that a group of nerve cells in the forebrain release the neurotransmitter dopamine when activated by tactile or certain visual stimuli. These dopaminergic nerve cells send connections to almost all parts of the brain and spinal cord, thereby affecting the functions of many circuits. These new findings could play a role in the future treatment of such illnesses as restless leg syndrome, a condition in which patients have unpleasant sensations in their limbs during sleep. The researchers have published their research results in the journal Current Biology.

Reducing the radioresistance of cancer

Most people recognize that many forms of cancer are treated with radiation therapy. However, some may not realize that there are cancer cells with the ability to survive this type of treatment. Oral squamous cell carcinoma (OSCC) is one of these forms of cancer, and is the reason why researchers from Kumamoto University in Japan began searching for methods to combat resistance to radiotherapy. Rather than going after the cancer cells directly, they attempted to find a way to control the biological mechanisms that aid in radioresistance. This meant looking at interleukin-6 (IL-6), a cytokine known for signaling the inflammatory response, and nuclear factor erythroid 2-related factor 2 (Nrf2), which is a protein that protects against oxidative stress.

CDC: higher risk of death from leading causes in rural America

Study: Heroin resurgence an 'unintended consequence' of attempt to curb OxyContin abuse

In an attempt to stem abuse of OxyContin, Purdue Pharma spent a decade and several hundred million dollars developing a version of the painkiller that was more difficult to snort, smoke or inject. Since those "abuse-deterrent" pills debuted six years ago, misuse of OxyContin has fallen and the company has touted them as proof of its efforts to end the opioid epidemic.

Older adults walk more for money and opportunity to donate to charity

Personal and social goals may be effective in motivating older adults to exercise, according to a study this month in the American Journal of Preventive Medicine from researchers at the Perelman School of Medicine at the University of Pennsylvania. Although numerous studies have demonstrated significant health benefits from walking - including decreased risk of heart disease, obesity, hypertension, and premature mortality - fewer than half of all adults achieve recommended levels of physical activity. Adults 65 and older are least likely to be physically active. In a 16 week period, both financial incentives and opportunity to donate to charity increased walking in older adults, by 2,348 steps and 2,562 steps per day, respectfully.

Farming of finfish, shellfish and plants in fresh and saltwater is the fastest-growing food production sector in the world and it's growing in Maine, too.

High-resolution pH imaging elucidates energy mechanisms in creating bacterial flagella

Bacterial cellular membranes protrude to form flagella, which are composed of up to about 30 distinct proteins and are essential for motility. The bacterial flagellar type III export apparatuses utilize energy derived from ATP hydrolysis and proton motive force (PMF) across the cell membrane to translocate flagellar proteins across the membrane. Previous studies have demonstrated that the flagellar transmembrane export gates play crucial roles in energy transduction to unfold and transport flagellar proteins for construction of  the flagella in a PMF-powered manner. However, the energy transduction mechanisms have not been completely understood.

Tremors in newborn piglets attributed to previously unidentified virus

Symptoms of tremors and shaking in newborn piglets are not a sign that the animals are cold, but rather that they are suffering from a specific viral infection. Researchers at Vetmeduni Vienna have now been able to prove this correlation for the first time using a newly developed test. The scientists detected a previously unknown virus, termed atypical porcine pestivirus (APPV), in "shaking piglets", making it possible to clearly diagnose the potentially fatal disease. The virus remains in the animals for a long time following an infection and may also be transmitted sexually. The findings were published in the journal Veterinary Research.

Video: Tracking data and shark behaviour
