The laws of attraction: Pheromones don't lie, fruit fly research suggests
For the first time, scientists have shown that a female fruit fly's pheromone signals can actually tell males how much energy her body has invested in egg production versus in storing away energy for her own survival. And it's a signal that she can't change in order to make herself more attractive.

New gene catalog of ocean microbiome reveals surprises
Oceanographers report completing the largest single-site microbiome gene catalog constructed to date. With this new information, the team discovered nutrient limitation is a central driver in the evolution of ocean microbe genomes.

Disrupted gut microbiome makes children more susceptible to amoebic dysentery
Children with lower diversity of microbial species in their intestines are more susceptible to severe infection with the Entamoeba histolytica parasite, according to a new study.

Top experts meet to advance holistic solutions to superbug infections spread by healthcare surfaces
(BLL Partners, LLC) Top experts in infection prevention and healthcare acquired infections (HAIs) are meeting in Dallas next week at the Healthcare Surfaces Summit 2017 to identify ways to reduce the rising menace from surface-spread healthcare-acquired superbug infections. Interdisciplinary teams representing multiple areas of expertise will collaborate to formulate integrated, actionable solutions from a holistic perspective. An HAI survivor and activist will keynote, illustrating the human and social costs of these devastating, but preventable diseases.

The Western Ghats of India revealed two new primitive species of earthworm
(Pensoft Publishers) Having conducted a survey of the earthworms in the Western Ghats mountains, India, a team of four scientists discovered two species new to science. Both belong to a primitive family. They are described in the open access journal ZooKeys.

Agroindustrial waste can be used as material for housing and infrastructure
(Fundação de Amparo à Pesquisa do Estado de São Paulo) Converting waste into resources, substituting toxic raw materials for healthy inputs, migrating from harmful to sustainable production processes. These are some of the guidelines for a research project about agroindustrial wastes and their potential use as appropriate materials for housing and infrastructure.

The proteins that domesticated our genomes

EPFL scientists have carried out a genomic and evolutionary study of a large and enigmatic family of human proteins, to demonstrate that it is responsible for harnessing the millions of transposable elements in the human genome. The work reveals the largely species-specific gene-regulatory networks that impact all of human biology, in both health and disease.

Human kidney progenitors isolated, offering new clues to cell renewal

In a first-of-its-kind look at human kidney development, researchers at The Saban Research Institute of Children's Hospital Los Angeles have isolated human nephron progenitor (NP) cells. Their results, published online in the journal Stem Cell Translational Medicine, will help scientists understand how these progenitor cells become renal cells in the developing fetus, and possibly offer a future way to foster renal regeneration after chronic kidney failure or acute injury.

Study reveals how ionising radiation damages DNA and causes cancer

For the first time, researchers from the Wellcome Trust Sanger Institute and their collaborators have been able to identify in human cancers two characteristic patterns of DNA damage caused by ionising radiation. These fingerprint patterns may now enable doctors to identify which tumours have been caused by radiation, and investigate if they should be treated differently.

International collaboration working to enhance protections for spinner dolphins
An international study involving researchers from Western Australia and the United States has unlocked a key behavioural schedule in spinner dolphins, which could provide crucial insight to conservation measures for the free-ranging animals.

Video: Tracking data and shark behaviour
Animals often share space as they move through their environment. Capturing these aggregations and co-occurrence events has proven extremely difficult in elusive, wide-ranging animals.

Tremors in newborn piglets attributed to previously unidentified virus
Symptoms of tremors and shaking in newborn piglets are not a sign that the animals are cold, but rather that they are suffering from a specific viral infection. Researchers at Vetmeduni Vienna have now been able to prove this correlation for the first time using a newly developed test. The scientists detected a previously unknown virus, termed atypical porcine pestivirus (APPV), in "shaking piglets", making it possible to clearly diagnose the potentially fatal disease. The virus remains in the animals for a long time following an infection and may also be transmitted sexually. The findings were published in the journal Veterinary Research.
