ROCHESTER, Minn. -- Could an unhealthy diet and lack of exercise be making you age faster? Researchers at Mayo Clinic believe there is a link between these modifiable lifestyle factors and the biological processes of aging. In a recent study, researchers demonstrated that a poor diet and lack of exercise accelerated the onset of cellular senescence and, in turn, age-related conditions in mice. Results appear today in Diabetes.

HSCT is an established procedure for many acquired and congenital disorders of the hematopoietic system, including disorders of the immune system, and as enzyme replacement in metabolic disorders.

In 1990, the EBMT introduced the Activity Survey, a novel tool for assessing the real picture of HSCT in Europe. On an annual basis, all EBMT members and affiliated teams report their number of transplant patients by indication, donor type and stem cell source.

Some people frequently check and re-check their mobile phones. Once this impulse is triggered, it may be more a question of not being able to leave the device alone than actually hoping to gain some reward from it. These insights are drawn from a study1 by psychologists Henry Wilmer and Jason Chein of Temple University in the US and are published in Springer's journal Psychonomic Bulletin & Review2. Their findings shed light on the reasons why some people are so attached to their smartphones and mobile technology, while others are less so.

Johns Hopkins scientists report they have developed an antibody against a specific cellular gateway that suppresses lung tumor cell growth and breast cancer metastasis in transplanted tumor experiments in mice, according to a new study published in the February issue of Nature Communications.

Compounds that stop a cellular rescue operation for stuck ribosomes may bolster the nation's defenses against biowarfare and bioterrorism, as well as create alternative antibiotics to handle increasingly resistant pathogens, according to a team of researchers.

(PHILADELPHIA) -- When women in labor are given more time to deliver their baby than current guidelines recommend, their incidence of cesarean delivery drops by 55 percent, say researchers at Thomas Jefferson University.

Snub-nosed moneys provide an excellent example of adaptive radiation and display uncommon ecological adaptations. They live along an elevation gradient from near sea level to beyond 4500m. Habitats differ according to elevation, and monkey's behaviour and ecology vary accordingly. R. avunculus are endemic to northern Vietnam, and found in subtropical forest on steep karst limestone, which are completely arboreal. R. brelichi generally ranges in a zone of mixed deciduous and evergreen broadleaf forest between 1500 and 2200m above sea level.

The head of The Innovation Group, Professor Rene Amalberti, has advised that healthcare systems must adapt in order to cope with our ageing populations. His editorial on the topic is published today in the International Journal for Quality in Health Care.

Professor Amalberti was speaking in anticipation of the publication of the editorial which discusses the impact of the current and escalating tsunami of ageing populations, which will present significant planning and budgetary challenges for global healthcare systems.

WASHINGTON, DC -- The repeated storms which battered Europe's Atlantic coastline during the winter of 2013/14 were the most energetic in almost seven decades, new research has shown.

They were part of a growing trend in stormy conditions which scientists say has the potential to dramatically change the equilibrium state of beaches along the western side of the continent, leading to permanent changes in beach gradient, coastal alignment and nearshore bar position.

Many insect species respond to danger by producing chemical alarm signals, or alarm pheromones, to inform others. In a recent study, investigators found that their alarm may be even be context dependent.

Snakes known to produce some of the most toxic venoms swim the shallows of the western Pacific and eastern Indian oceans and sun themselves on island coasts from southwestern Japan to Indonesia, the Andaman Islands to Fiji.

But to find banded sea kraits, ask a guy in Cleveland. Or at least look up his work.

MEDFORD/SOMERVILLE, Mass. (March 16, 2016) -- Tufts University biologists using a frog model have demonstrated for the first time that it is possible to prevent tumors from forming and normalize tumors after they have formed by using light to control electrical signaling among cells. The work, which appears online in Oncotarget on March 16, 2016 is the first reported use of optogenetics to specifically manipulate bioelectrical signals to both prevent and cause regression of tumors induced by oncogenes.

BOULDER - Key factors that can combine to produce a Zika virus outbreak are expected to be present in a number of U.S. cities during peak summer months, new research shows.

The Aedes aegypti mosquito, which is spreading the virus in much of Latin America and the Caribbean, will likely be increasingly abundant across much of the southern and eastern United States as the weather warms, according to a new study led by mosquito and disease experts at the National Center for Atmospheric Research (NCAR).

Among comatose survivors of out-of-hospital cardiac arrest, treatment with inhaled xenon gas combined with hypothermia, compared with hypothermia alone, results in less white matter damage. This was the primary outcome in a randomized clinical trial that was funded by the Academy of Finland and the Hospital District of Southwest Finland. In the secondary outcome, for which the study was not powered, there was no significant difference in neurological outcomes or death at six months.

Spanish researchers have studied the relationship between hormones and aggressive behaviour in girls and boys between the ages of eight and ten. The results, published in the American Journal of Human Biology, confirm that the subjects who experienced the greatest increase in levels of aggression by ten years of age were those whose cortisol levels had also increased during those two years.
