Exoplanet around distant star resembles reputed 'Planet Nine' in our solar system

Astronomers think planets can exist in orbits far from their star, and propose a two-step process: interactions with the star or inner planets kick it out of the inner system, and then a passing star stabilizes the orbit to keep it bound. Such a scenario could explain the hypothesized 'Planet Nine' in our solar system. Astronomers has now confirmed that one binary star system, HD 106906, has a planet in a bound, highly eccentric orbit.

Evolution may be to blame for high risk of advanced cancers in humans

Compared to chimpanzees, our closest evolutionary cousins, humans are particularly prone to developing advanced carcinomas -- the type of tumors that include prostate, breast, lung and colorectal cancers -- even in the absence of known risk factors, such as genetic predisposition or tobacco use. A recent study helps explain why.

How the brain remembers right place, right time

Two new studies shed new light on how the brain encodes time and place into memories. The findings not only add to the body of fundamental research on memory, but could eventually provide the basis for new treatments to combat memory loss from conditions such as traumatic brain injury or Alzheimer's disease.

Neanderthals buried their dead: New evidence

Was burial of the dead practiced by Neanderthals or is it an innovation specific to our species? Researchers have demonstrated, using a variety of criteria, that a Neanderthal child was buried, probably around 41,000 years ago, at the Ferrassie site (Dordogne, France).

Paleontologists find pterosaur precursors that fill a gap in early evolutionary history

With the help of newly discovered skulls and skeletons that were unearthed in North America, Brazil, Argentina, and Madagascar in recent years, researchers have demonstrated that a group of 'dinosaur precursors,' called lagerpetids, are the closest relatives of pterosaurs.

Obesity impairs immune cell function, accelerates tumor growth

A new study in mice finds that a high-fat diet allows cancer cells to outcompete immune cells for fuel, impairing immune function and accelerating tumor growth. Cancer cells do so by rewiring their metabolisms to increase fat consumption. Blocking this rewiring enhances anti-tumor immunity. The findings suggest new strategies to target cancer metabolism and improve immunotherapies.

Science of sandcastles is clarified, finally

New research provides a solution for the century-and-half-old puzzle of why capillary condensation, a fundamentally microscopic phenomenon involving a few molecular layers of water, can be described reasonably well using macroscopic equations and macroscopic characteristics of bulk water. Is it a coincidence or a hidden law of nature?

Spiders in space: Without gravity, light becomes key to orientation

Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought.

New superhighway system discovered in the Solar System

Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and asteroids near Jupiter to Neptune's distance in under a decade and to 100 astronomical units in less than a century. They could be used to send spacecraft to the far reaches of our planetary system relatively fast, and to monitor and understand near-Earth objects that might collide with our planet.
