Women who trekked across Antarctica in the first-ever all-female expedition broke more than gender norms — they also busted the gender myth that, when it comes to extreme endurance exercise, women are weaker than men.
Sorry men, that’s not the case.
“Our findings contain some potentially myth-busting data on the impact of extreme physical activity on women,” lead study author Dr. Robert Gifford, of the University of Edinburgh’s Centre for Cardiovascular Science, said in a statement. “We have shown that with appropriate training and preparation, many of the previously reported negative health effects [of extreme exercise on women] can be avoided.”

ASHEVILLE, North Carolina — A chickenpox outbreak at a private school now ranks as North Carolina’s largest since a vaccine for the virus became available more than 20 years ago, health officials say.
As of Friday, 36 students at Asheville Waldorf School had contracted the varicella virus, known to most as chickenpox. The school has one of the highest vaccination religious exemption rates in the state.
The viral infection manifests in an itchy rash in most cases and is not typically life-threatening. But the outbreak at Asheville Waldorf should cause concern, said Dr. Jennifer Mullendore of Buncombe County Department of Health and Human Services.

Carbon fiber composites—lightweight and strong—are great structural materials for automobiles, aircraft and other transportation vehicles. They consist of a polymer matrix, such as epoxy, into which reinforcing carbon fibers have been embedded. Because of differences in the mechanical properties of these two materials, the fibers can detach from the matrix under excessive stresses or fatigue. That means damage in carbon fiber composite structures can remain hidden below the surface, undetectable by visual inspection, potentially leading to catastrophic failure.

The company-funded animal test was performed to ascertain how neural development is affected by the pesticide chlorpyrifos, which is used on a wide variety of crops around the world, including some 20 EU countries. The test laboratory concluded that there was no such effect, even at high doses.
Academic researchers have examined raw data from a company-funded safety evaluation of the pesticide chlorpyrifos. They discovered an effect on the brain architecture of the exposed laboratory animals at all tested doses, which was not included in the reported conclusions. Karolinska Institutet in Sweden led this independent study, which is published in the scientific journal Environmental Health.
All pesticides must be evaluated in terms of their safety and potential risks for human health before they can officially be approved. Normally the companies that manufacture the products cover the cost of such evaluations and commission test laboratories to perform the necessary animal tests.
Assistant professor Axel Mie at Karolinska Institutet, Christina Rudén at Stockholm University and Philippe Grandjean at Harvard School of Public Health have examined a case in which independent research and company-funded tests deviated, at least in terms of the conclusions drawn in the industry-funded study.
Research led by the University of Bristol has begun to unpick an important mechanism of antibiotic resistance and suggest approaches to block this resistance.
Antibiotic resistance is the ability of bacteria to defend against antibiotic attack, and the spread of these resistance mechanisms amongst bacteria is a global public health concern. A form of resistance caused by a family of bacterial proteins, the Verona Imipenemase (VIM) beta-lactamases, is of acute clinical concern because it can inactivate antibiotics (penicillins and related agents) that comprise over half of the global antibacterial market.
A team of researchers led by the University of Bristol have uncovered near-atomic level structural detail of VIM proteins. The research is published today [Thursday 15 November] in The FEBS Journal.
