During their annual Winter Study at Isle Royale National Park, scientists from Michigan Technological University counted nine wolves organized into one breeding pack and a second small group that is a remnant of a formerly breeding pack.

In the Isle Royale Wolf-Moose Study’s annual report released today, the researchers say that over the past three years, they have tallied the lowest numbers of wolves ever: nine in 2011–12, eight in 2012–13 and nine in 2013–14. During the same period, predation rates—the proportion of the moose population killed by wolves—also dropped to the lowest ever recorded, while the number of moose doubled, to approximately 1,050 moose.

Privacy discussions of modern times have four pillars - and they are all weak, according to a new article.

There are four main arguments about privacy: (1) it is dead; (2) people don't care about privacy and modern youth care even less; people with nothing to hide have nothing to fear; and privacy is bad for business.
A paper in Zootaxa describes a new species of spider, Cebrennus rechenbergi, the only spider that is able to move by means of flic-flac jumps. 

The nocturnal spider Cebrennus rechenbergi lives in the sand desert Erg Chebbi in southeastern Morocco, not far from the Algerian border.

Smallpox as a disease is dead and has been since 1980. Should we let the virus behind it die?

Variola, the virus that causes smallpox, is on the agenda of the upcoming meeting of the World Health Assembly (WHA), the governing body of the World Health Organization, which is part of the United Nations.

The UN would like to destroy the last known remaining live strains of the virus  but an international group of scientists led by Inger Damon, from the US Centers for Disease Control and Prevention, argue that the WHA should not choose destruction, because crucial scientific questions remain unanswered and important public health goals unmet. 

Corn yields in the central United States have increased dramatically in the last few decades - but they have also become more sensitive to drought conditions.

A clinical trial involving 14 sites provides new evidence on a growing controversy in the medical community – whether treating infants with steroids to augment surgery improves outcomes. 

A presentation at the annual meeting of the Pediatric Academic Societies in Vancouver discussed the risk of nutritional deficiencies in severely obese teens – including in those who had weight loss surgery.

At least five years after undergoing gastric bypass surgery, teens and young adults maintained significant weight loss but were at risk of nutritional deficiencies, particularly low iron, mild anemia and low vitamin D. The study also found low iron and low vitamin D in severely obese teens who did not undergo weight loss surgery. Those who didn't have surgery also had low levels of protein in their blood.

Chicago, IL (May 4, 2014) — Despite being of a healthier weight, lean patients with nonalcoholic fatty liver disease (NAFLD) have a higher overall mortality rate than patients with NAFLD who are overweight or obese, according to new research presented today at Digestive Disease Week® (DDW). In addition to finding higher mortality rates, an international team of researchers found that lean patients [a body mass index (BMI) less than 25] with NAFLD were more likely to be male, non-Caucasian and to have lower rates of chronic conditions, such as diabetes and hypertension.

Researchers have taken an atomic level look at the enzyme telomerase - and what they have found may unlock the secrets to the fountain of youth.

Telomeres and the enzyme telomerase have been in the medical news a lot recently due to their connection with aging and cancer. Telomeres are found at the ends of our chromosomes and are stretches of DNA which protect our genetic data, make it possible for cells to divide, and hold some secrets as to how we age –and also how we get cancer.

Brittle bone disease is a congenital disorder that results in fragile bones that break easily.  

A new study in Nature Medicine showed that excessive activity of an important signaling protein in the matrix of the bone called transforming growth factor beta is associated with the cause of the disease. It suggests that there may be common mechanisms that cause the decreased quality and quantity of bone in these different forms. 

"There are many genetic causes of brittle bone disease in children and adults," said Dr. Brendan Lee, professor of molecular and human genetics at Baylor and a Howard Hughes Medical Institute investigator. "We have discovered many of them but clinicians still cannot easily distinguish the different forms.
