Manufacturers of feminine hygiene products, including tampons and sanitary products, could dedicate a part of their revenues to support public health programmes that prevent violence against women, argues an expert in The BMJ this week.

Physical and sexual violence is a public health problem that affects more than one third of all women, equivalent to at least a billion women globally, according to a World Health Organization (WHO) study.

Effective programmes and strategies to prevent domestic and sexual violence, the two most common types, have been identified by the WHO and collaborators, but these are "hugely underfunded", argues Dr S D Shanti, associate professor of public health from the A T Still University of Health Sciences, USA.

Human use of artificial light is causing Spring to come at least a week early in the UK, researchers at the University of Exeter in Cornwall have found.

New research led by a team of biologists based at the University's Penryn campus highlights for the first time and at a national scale the relationship between the amount of artificial night-time light and the date of budburst in woodland trees.

Our ancestors evolved three times faster in the 10 million years after the extinction of the dinosaurs than in the previous 80 million years, according to UCL researchers.

The team found the speed of evolution of placental mammals -- a group that today includes nearly 5000 species including humans -- was constant before the extinction event but exploded after, resulting in the varied groups of mammals we see today.

Lead researcher, Dr Thomas Halliday (UCL Genetics, Evolution & Environment), said: "Our ancestors -- the early placental mammals - benefitted from the extinction of non-avian dinosaurs and dwindling numbers of competing groups of mammals. Once the pressure was off, placental mammals suddenly evolved rapidly into new forms.

BOSTON - The rapid development of a safe and effective vaccine to prevent the Zika virus (ZIKV) is a global priority, as infection in pregnant women has been shown to lead to fetal microcephaly and other major birth defects. The World Health Organization declared the Zika virus epidemic a global public health emergency on February 1, 2016.

LEXINGTON, Ky. (June 28, 2016) -- In a surprising reversal, researchers have determined that a particular protocol providing physical therapy to ICU patients with acute respiratory failure did not shorten hospital length of stay.

Secondary measures of physical function and health-related quality of life were split.

The study, which is the largest to-date on this topic, was not able to confirm the findings from earlier pilot and quality improvement studies.

SILVER SPRING, Md. - The Walter Reed Army Institute of Research (WRAIR) and collaborators at the Beth Israel Deaconess Medical Center and Harvard Medical School have completed a promising preclinical study of two Zika vaccine candidates that suggests that an effective human vaccine will be achievable. Findings from the study were published today in the journal Nature.

In the preclinical study, WRAIR and the Beth Israel Deaconess Medical Center tested two Zika virus vaccine candidates: a DNA vaccine developed at Harvard based on a Zika virus strain isolated in Brazil, and a purified inactivated virus vaccine developed at WRAIR based on a Zika virus strain isolated in Puerto Rico.
