A University of Miami math professor has developed a scientific model to address the various ways the Zika virus proliferates. The study, published June 17, 2016 in Scientific Reports, reveals that mosquito control should remain the most important mitigation method to control the virus. However, the study reveals that Zika is a complicated virus and sexual transmission increases the risk of infection and prolongs the outbreak.

CORAL GABLES, Fla. (June 28, 2016) - Before British long jumper Greg Rutherford departs for the Olympic Games in Rio de Janeiro this summer, he'll leave an important part of himself behind: a sample of his frozen sperm.

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.

A single dose of either of two experimental Zika vaccines fully protected mice challenged with Zika virus four or eight weeks after receiving the inoculations. The research, conducted by investigators supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, suggests that similar vaccines for people could be similarly protective.

Species across the world are rapidly going extinct due to human activities, but humans are also causing rapid evolution and the emergence of new species. A new study published today summarises the causes of manmade speciation, and discusses why newly evolved species cannot simply replace extinct wild species. The study was led by the Center for Macroecology, Evolution and Climate at the University of Copenhagen.

A common close partnership which sees baby fish sheltering from predators among the poisonous tentacles of jellyfish will be harmed under predicted ocean acidification, a new University of Adelaide study has found.

Published today in the journal Proceedings of the Royal Society B, the researchers say that modification of this baby fish-jellyfish symbiotic relationship is likely to lead to higher mortality among the affected fish species which include some of the common commercial fish. A well-known example of marine symbiosis is the relationship between anemones and clown-fish, popularised in the animated movie, Finding Nemo.
