A new gene for canine congenital eye disease has been identified by a collaborative research led by Professor Hannes Lohi's research group in the University of Helsinki. Defective RBP4 leads to vitamin A deficiency and abnormal eye development during pregnancy. The study defines a novel recessive mode of maternal inheritance, which may underlie other types of birth defects. (2018-05-29)

Wars and clan structure may explain a strange biological event 7,000 years ago
Genetic data suggest there was a collapse in male, but not female, genetic diversity starting 7,000 years ago. The reason may be wars between clans structured around male ancestry. (2018-05-29)

For banded mongooses, 'cultural inheritance' decides what's for dinner
It's no surprise that people behave differently depending upon what they've learned from other people, from the language they speak to the foods they like to eat. But now researchers reporting in Current Biology on May 24 have found that the same is true of banded mongooses. (2018-05-24)

Mongooses inherit behavior from role models rather than parents
Young mongooses learn lifelong habits from role models rather than inheriting them from genetic parents, new research shows. (2018-05-24)

Imminent extinction of northern white rhinoceros motivates new genetic recovery efforts
In a study published today in the journal Genome Research, researchers investigated the genetic history of nine northern white rhino (NWR) cryopreserved cell lines compared to that of a closely related subspecies, the southern white rhino (SWR). Importantly, genetic analyses of variation and inbreeding facilitated identification of cell lines, which may serve as valuable pools of genetic material for genetic rescue. (2018-05-24)

Genetic diversity helps protect against disease
So much for survival of the fittest -- diversity is the key: a team of researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) has succeeded in demonstrating experimentally that genetic diversity makes populations more resistant to disease. (2018-05-23)

Friends influence middle schoolers' attitudes toward peers of different ethnicities, races
Studies have shown that for young people, simply being around peers from different ethnic and racial backgrounds may not be enough to improve attitudes toward other groups. Instead, children and adolescents also need to value spending time and forming relationships with peers from diverse groups. A new study examined how friends in middle school affect each other's attitudes about interacting with peers of different ethnicities and races, finding that they significantly influence each other's racial and ethnic views. (2018-05-22)

(2018-05-21)

The chestnut gall wasp -- The threat of an invasive species with clonal reproduction
A molecular study carried out on the chestnut gall wasp, Dryocosmus kuriphilus, has revealed the absence of genetic variability in this invasive species, a chestnut-tree parasite, in Europe. This is due to the fact that the wasp's reproduction is strictly parthenogenetic, the females produce more females without having to be fertilized by a male. The high capacity of reproduction of the females, producing genetically identical daughters, give this insect a high invasive potential. (2018-05-21)

Whole-tree logging may not hinder plant biodiversity
When it comes to timber harvesting, removing the whole tree -- from stump to twigs -- doesn't reduce plant diversity any more than old-fashioned logging, which leaves tree branches behind in the woods. (2018-05-16)

Think chimpanzee beds are dirtier than human ones? Think again
Chimpanzees (Pan troglodytes) appear to keep tidier sleeping arrangements than humans do. That's one finding of a recent study that evaluated the microbes and arthropods found in the treetop beds that chimpanzees make each night. (2018-05-15)

American tropics, Amazon origins
A new study, co-authored by Harvard Visiting Scholar Alexandre Antonelli and an international team of researchers, is suggesting many of the plants and animals that call Latin America home may actually have their roots in the Amazon. Researchers found that a dynamic process of colonization and speciation led to the formation of the American tropics, which is today the most species-rich region on the planet. (2018-05-14)

Genetic clues reveal origins of killer fungus behind the 'amphibian plague'
A deadly fungus responsible for the devastation of amphibian populations around the world may have originated in East Asia, new research has found. (2018-05-10)

A European origin for leprosy?
New research by an international team has revealed that there was much more diversity in the leprosy strains circulating in Medieval Europe than previously thought. This finding, based on the sequencing of 10 new ancient genomes from the leprosy-causing bacterium Mycobacterium leprae, complicates prior assumptions about the origin and spread of the disease, and also includes the oldest M. leprae genome sequenced to date, from about 400 AD in the United Kingdom. (2018-05-10)

New link between gut microbiome and artery hardening discovered
The level of diversity of the 'good bacteria' in our digestive systems has been found to be linked to a feature of cardiovascular disease -- hardening of the arteries -- in new research by experts at the University of Nottingham and King's College London. (2018-05-10)

Darwin's finches -- where did they actually come from?
In 1835, Charles Darwin visited the Galapagos Islands and discovered a group of birds that would shape his groundbreaking theory of natural selection. Darwin's finches are now well-known as a textbook example of animal evolution. But just where did a species synonymous with the discovery of evolution come from? A new study from The Auk: Ornithological Advances presents some of the best models to date on where these birds actually originated. (2018-05-09)

Despite mutations in makona Ebola virus, disease consistent in mice, monkeys
Early during the West African Ebola epidemic, scientists speculated that the genetic diversity of the Makona strain of virus (EBOV-Makona) would result in more severe disease and more transmissibility than prior strains. However NIH scientists have determined that certain mutations stabilized early during the epidemic and did not alter Ebola disease presentation or outcome. Their work offers evidence to support previous findings that the diversity of EBOV-Makona did not significantly impact the course of disease. (2018-05-08)

Inequality is normal: Dominance of the big trees
The top 1 percent of the forest has been sharing some vital information with researchers. Ninety-eight scientists and thousands of field staff have concluded the largest study undertaken to date with the Smithsonian Forest Global Earth Observatory (ForestGEO), and what they have found will have profound implications toward ecological theories and carbon storage in forests. (2018-05-08)

Urine of kidney disease patients contains diverse mix of bacteria
The urine of kidney disease patients contains a diverse mix of bacteria such as Staphylococcus and Streptococcus, according to a Loyola study. The bacteria diversity generally was higher among kidney patients who also experienced urinary urgency (sudden, urgent need to urinate). The findings could lead to new approaches to treating lower urinary tract problems such as urinary urgency and incontinence. (2018-05-04)

Largest-ever family study of migraine provides new insight into the disease
An international research consortium has shown that an accumulation of many independent genetic risk variants is the reason why migraine tends to run in families. The genetic burden was shown to be greater in patients that experience aura symptoms during attacks or have an early age of onset of migraine. (2018-05-03)

Rare sharks are no longer in the 'dark,' thanks to new species survey method
Previously unobserved shark species swim in areas impacted by humans, reports a new study. The results reveal a greater prevalence of sharks in such regions than traditional survey methods have uncovered, and the approach for uncovering them may lead to more thorough species diversity assessments in areas with rare and threatened large animals - often hard to (2018-05-02)
