Extremely Hot and Incredibly Close: How Hot Jupiters Defy Theory

Paul Sutter is a visiting scholar at The Ohio State University's Center for Cosmology and Astro-Particle Physics (CCAPP). In fact, in the early days of a solar system's formation, planets are a little rambunctious: squirrely little toddlers jostling about underfoot.

Zika Virus Linked to Stillbirth

A woman in Brazil who became infected with the Zika virus gave birth to a stillborn baby, and large parts of the infant's brain were missing, according to a new report. Moreover, the fetus had damage to tissues outside of the central nervous system, the researchers said. "These finding raise concerns that the virus may cause severe damage to fetuses leading to stillbirths, and may be associated with effects other than those seen in the central nervous system," study author Dr. Albert Ko, chair of the Department of Epidemiology of Microbial Diseases at the Yale School of Public Health, said in a statement.

Ebola May Leave Survivors with Lasting Problems in Brain, Nerves

Although experts recently declared the world's largest Ebola outbreak over, many people who were infected with the virus are still experiencing neurologic problems, according to a new study. Researchers found that, among a group of 82 Ebola survivors in Liberia, nearly all had some neurologic problems at six months or longer after they were infected. "While an end to the outbreak has been declared, these survivors are still struggling with long-term problems," study author Dr. Lauren Bowen, a neurologist at the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland, said in a statement.

Palm-Size Satellites Could Hunt for New Alien Worlds

Tiny satellites could hitch a ride into orbit and spot alien worlds from afar, new research suggests. NASA's 2,230 pound (1,052 kilogram) Kepler Space Telescope has discovered thousands of potential planets around other stars. Now, some scientists want to go smaller: They propose searching for new worlds using miniaturized satellites that can fit in the palm of your hand.

Gravitational Waves: Did Merging Black Holes Form from Single Star?

Could a single, dying star give birth to not one, but two black holes? Scientists have long held different ideas about how black holes of this size get close enough to collide, but another proposal has just entered the ring: that the black holes were created, shortly before their collision, from one, massive star as it was collapsing in on itself. This new hypothesis posits that the merger of these two black holes would produce light — including, possibly, a burst of gamma-rays, the highest-energy form of light.

Vital to food output, bees and other pollinators at risk

By Alister Doyle OSLO (Reuters) - Bees and other pollinators face increasing risks to their survival, threatening foods such as apples, blueberries and coffee worth hundreds of billions of dollars a year, the first global assessment of pollinators showed on Friday. Pesticides, loss of habitats to farms and cities, disease and climate change were among threats to about 20,000 species of bees as well as creatures such as birds, butterflies, beetles and bats that fertilize flowers by spreading pollen, it said. ...
