Human antibodies from Dengue patients effectively treat Zika infection in mice
Human antibodies from Dengue patients effectively treat Zika infection in mice
Scientists have discovered that antibodies taken from patients infected with Dengue virus are effective in treating Zika infection in rodents. The team, led by researchers at Imperial College London and Washington University in St Louis, found that giving Zika-infected mice the antibodies was enough to treat the early stages of infection, and even protected unborn pups in pregnant animals.

Brain damage in fish affected by plastic nanoparticles
Brain damage in fish affected by plastic nanoparticles
A new study from Lund University in Sweden shows that plastic particles in water may end up inside fish brains. The plastic can cause brain damage, which is the likely cause of behavioural disorders observed in the fish. Calculations have shown that 10 per cent of all plastic produced around the world ultimately ends up in the oceans.

Study will test new technique to prevent viral infections during pregnancy
Dr. Michelle Silasi, Assistant Professor of Obstetrics, Gynecology, and Reproductive Sciences, will test the effectiveness of a new technique to screen for viral exposure during pregnancy that can identify women at risk for serious complications and allow for interventions to improve pregnancy outcomes.

Tiny diamonds could become best friends to youths with cleft palates
Tiny diamonds could become best friends to youths with cleft palates
Young people with cleft palate may one day face fewer painful surgeries and spend less time undergoing uncomfortable orthodontic treatments thanks to a new therapy developed by researchers from the UCLA School of Dentistry. The treatment incorporates a shiny twist: diamond fragments so small it would take more than 3 million of them to span the diameter of a penny.

First large-scale ancient DNA study helps reconstruct African population structure
First large-scale ancient DNA study helps reconstruct African population structure
Samples of ancient DNA recovered by University of Bristol scientists on two Indian Ocean islands have helped in the first large scale study of ancient human DNA from sub-Saharan Africa. Africa has long been known as the 'cradle of mankind', but up to now, the genetic information has been largely derived from modern population studies.

Virtual reality tool developed to untangle genes
Researchers from Oxford have been using virtual reality software to compile genetic data to create models which explain how genes are controlled within their natural chromosomal environments. The team from the MRC Weatherall Institute of Molecular Medicine (WIMM) have been working in collaboration with physicists from Universita' di Napoli and software developers and artists at Goldsmiths, University of London, to visualise complex interactions between genes and their regulatory elements in an interactive format.

"Humanized" Mouse Model Developed to Study Hepatitis B Infection
The ANRS consortium "Humanized Mouse Models for Viral Hepatitis"1, made up of 6 teams of researchers, has developed a mouse model for studying the interaction between the immune system and the liver following infection by the hepatitis B virus. This research, coordinated by Dr. Hélène Strick-Marchand (Inserm joint unit 1223, "Physiopathology of the Immune System", Institut Pasteur), responds to a real lack of animal models for studying this disease and thus opens up the possibilities for evaluating new therapeutic strategies.

The Surprising, Ancient Behavior of Jellyfish
The Surprising, Ancient Behavior of Jellyfish
At first glance, humans seem to have very little in common with Cassiopea, a primitive jellyfish. Cassiopea is brainless, spineless, and spends essentially its entire life sitting upside down on the ocean floor, pulsating every few seconds. However, Caltech scientists have now discovered that, as different as our daily schedules may seem, humans and jellyfish actually start and end their days with the same behavior: sleep.

Tumor metabolism helps classify hepatoblastoma
Tumor metabolism helps classify hepatoblastoma
Looking at cell metabolism instead of histology, EPFL scientists have identified new biomarkers that could help more accurately classify the two main subtypes of hepatoblastoma, a liver cancer in children. Hepatoblastoma is a rare pediatric liver cancer, usually diagnosed in the first three years of life.

Genome editing reveals role of gene important for human embryo development
Genome editing reveals role of gene important for human embryo development
Researchers have used genome editing technology to reveal the role of a key gene in human embryos in the first few days of development. This is the first time that genome editing has been used to study gene function in human embryos, which could help scientists to better understand the biology of our early development.

10,000 year-old DNA proves when fish colonialized our lakes
DNA in lake sediment forms a natural archive displaying when various fish species colonized lakes after the glacial period. This according to researchers at the Department of Ecology and Environmental Science at Umeå University in a study published in the journal Methods in Ecology and Evolution. Their analyses of the prevalence of whitefish DNA in sediment reveal that the whitefish came to Lake Stora Lögdasjön in Västerbotten already 10,000 years ago, whereas Lake Hotagen in Jämtland had its whitefish only 2,200 years ago.

National Cancer Institute designates UCLA brain cancer program a site of research excellence
The brain cancer program at UCLA's Jonsson Comprehensive Cancer Center and the UCLA Brain Tumor Center has been designated a Specialized Program of Research Excellence, or SPORE, by the National Cancer Institute, making it one of only five brain cancer programs nationwide to receive this national recognition and substantial research funding.

Size matters in battle against extinction, scientists find
Researchers have found the Goldilocks zone for animals lies in being mid-sized, with apex predators over-hunted and small vertebrates like pollinators threatened by habitat changes because they cannot move far from home. Quick overview of the findings Filmed by Dr Newsome; edited by the Australian Science Media Centre.

Study uncovers markers for severe form of multiple sclerosis
Scientists have uncovered two closely related cytokines - molecules involved in cell communication and movement - that may explain why some people develop progressive multiple sclerosis (MS), the most severe form of the disease. The findings, authored by researchers at Yale University, Oregon Health & Science University, and the University of California point the way toward developing a novel treatment to prevent progressive forms of the disease.

Analyzing the language of color
Analyzing the language of color
The human eye can perceive millions of different colors, but the number of categories human languages use to group those colors is much smaller. Some languages use as few as three color categories (words corresponding to black, white, and red), while the languages of industrialized cultures use up to 10 or 12 categories.

Blood testing via sound waves may replace some tissue biopsies
Blood testing via sound waves may replace some tissue biopsies
Cells secrete nanoscale packets called exosomes that carry important messages from one part of the body to another. Scientists from MIT and other institutions have now devised a way to intercept these messages, which could be used to diagnose problems such as cancer or fetal abnormalities. Their new device uses a combination of microfluidics and sound waves to isolate these exosomes from blood.

Eyes that lie: protective deception of eyespots confirmed
Eyes that lie: protective deception of eyespots confirmed
The widespread occurrence of eyespots, from butterflies to fish, has intrigued biologists for years but the mechanism behind their function has, until now, remained unclear. New evidence published recently in The American Naturalist shows that prey eyespots intimidate predators because they associate the eyelike appearance of eyespots with the threat posed by their own enemy.
