First polluted white dwarf found in Gaia DR2

Astronomers have identified the first metal-polluted white dwarf star from the Gaia Data Release 2 (DR2) provided by ESA's Gaia satellite. The newly found star received designation GaiaJ1738−0826. The finding is detailed in a paper published June 24 on the arXiv pre-print repository.

Einstein gets it right again—weak and strong gravity objects fall the same way

Einstein's understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their mass or composition. This theory has passed test after test here on Earth, but does it still hold true for some of the most massive and dense objects in the known universe, an aspect of nature known as the Strong Equivalence Principle? An international team of astronomers has given this lingering question its most stringent test ever. Their findings, published in the journal Nature, show that Einstein's insights into gravity still hold sway, even in one of the most extreme scenarios the Universe can offer.

Einstein's theory of gravity holds – even in extreme conditions

Drop a marble and a cannon ball off the Leaning Tower of Pisa at the same time and they will hit the ground at the same time. That fact is explained by Albert Einstein's theory of gravity—general relativity—which predicts that all objects fall in the same way, regardless of their mass or composition.

The Gaia Sausage: The major collision that changed the Milky Way galaxy

An international team of astronomers has discovered an ancient and dramatic head-on collision between the Milky Way and a smaller object, dubbed the "Sausage" galaxy. The cosmic crash was a defining event in the early history of the Milky Way and reshaped the structure of our galaxy, fashioning both its inner bulge and its outer halo, the astronomers report in a series of new papers.

Skin cancers can be divided into two types – nonmelanoma (basal and squamous cell carcinomas) and melanoma, with melanoma being the least common but most life-threatening. Each year, some 90,000 people are diagnosed with melanoma. Sarah Arron, MD, Ph.D., shares her thoughts on skin cancer prevention and helps separate the facts from the hype.

Cost-effective universal screening for hepatitis C in France

An estimated 75,000 people in France are unaware they are infected by hepatitis C virus. An ANRS-funded study by Sylvie Deuffic-Burban, Ph.D., a research associate at IAME (Infection, Antimicrobials, Modeling, Evolution) (Inserm—Université Paris Diderot—Université Paris 13), and her team show that a universal screening strategy applied to hepatitis C is cost-effective and improves life expectancy in those infected, compared with targeted screening. These modeling results are published in the Journal of Hepatology.

Clinics manage hypertension patients better when more hands are on deck

South Africa's clinic based health system was originally created to provide primary care services like maternal and child care and care for acute conditions such as pneumonia or malaria. But the clinics have been facing rapidly increasing demand for a range of additional services. This is partly because of the need to provide antiretroviral drugs at clinic level and partly because there is an increasing number of older South Africans who have chronic conditions like high blood pressure (hypertension).

Piping plovers want people to get off their lawn

A new study in The Condor: Ornithological Applications presents negative associations between anthropogenic disturbance (human recreational use of beaches, coastal modifications) and Piping Plovers on their non-breeding grounds. Shorebirds are one of the most threatened bird families in the world. Numerous studies have shown the negative impacts of humans on these birds, whether it be large-scale (e.g., habitat loss, climate change) or small-scale (e.g., ATV use, running with pets, flying kites). This research indicates that there are direct consequences of disturbance. Most Piping Plover research has focused on the breeding season in an attempt to directly influence population numbers, however this study argues that efforts are required throughout the year in all locations to assist Piping Plover conservation.

To help save northern spotted owls, we need to prevent kissing cousins

The Auk: Ornithological Advances presents a study on a Northern Spotted Owl pedigree, consisting of almost 14,200 individuals over 30 years, which determined inbreeding varies across the species' range. Selection against inbreeding based on decreased future reproduction, fewer offspring, and overall survival of individuals was also supported. These results indicate that Spotted Owl conservation efforts need to address owl breeding more. Another implication of this work is the need to increase genetic diversity to prevent further population decline.

Crows are always the bullies when it comes to fighting with ravens

A study from The Auk: Ornithological Advances presents citizen science data which supports that American Crows and Northwestern Crows almost exclusively (97% of the time) instigate any aggressive interactions with Common Ravens no matter where in North America. The data showed that aggression by crows was most frequent during the breeding season, most likely due to nest predation by ravens. This study not only gives insight into interspecies dynamics, but also how citizen science data can aid behavioral studies at large geographic scales.

SATB1 vital for maintenance of hematopoietic stem cells
