Battle of the deer and eagle

Spoiler alert: eagle wins

DEER VS. EAGLE A camera trap solved the mystery of a deer carcass discovered in the snow. It was killed by a predator that left no tracks.

When a deer carcass appeared a few meters from a camera trap without obvious predator prints, scientists were a bit puzzled.

The mystery was only solved when the team reviewed 2-week-old footage from their camera and saw images of an adult golden eagle tearing into the back of a young sika deer. It was a rare sight, the first reported in the extreme eastern regions of Russia, the scientists suggest.

They published the images and a paper on the predator-prey interaction in the September Journal of Raptor Research.

Last gorge for galaxy’s central black hole gauged

Relic light suggests the supermassive black hole at the Milky Way's center was millions of times more active 2 million years ago.

Class of toxins linked to IQ deficits dropped drastically in three years, a new study shows.

Greenland Sea warming faster than world ocean

Deep water temperature of Greenland Sea rises 0.3 degrees Celsius in 30 years.

Quake forms island in Arabian Sea

A new island has sprung to the surface of the Arabian Sea. The island sits just off the southern coast of Pakistan and formed after a magnitude 7.7 earthquake rocked the western part of the country on September 24. The quake probably shook loose methane gas and water trapped in the sea sediments and forced part them to the water’s surface. The process has formed islands in the Arabian Sea in the past, according to a recent study in Nature Geoscience.

Titan's plastic atmosphere

Saturn's moon Titan has an ingredient of plastic in its atmosphere.

New data from the Cassini spacecraft shows that the moon's lower atmosphere contains molecules of propylene, which is used to make plastic containers and other products on Earth.

The propylene discovery came as no surprise to astronomers, who have been searching for the molecule in Titan’s atmosphere since the Voyager 1 spacecraft flew by the moon in 1980. The scientists had found other light and heavy carbon-based molecules on the moon but never this plasticlike one.

Fomalhaut star system is a triple

Planets and debris aren’t the only things gravitationally bound to Fomalhaut A, a star twice the mass of the sun that sits 25 light-years away in the constellation Piscis Austrinus. It turns out that not one but two other stars are also in its clutches. Astronomers describe the triple star system in a paper posted October 3 on arXiv.org and accepted for publication in the Astronomical Journal. The team notes that the Fomalhaut triple system is one of the most massive and widest among multiple-star systems closest to Earth.

Higgs boson’s effects on universe boosted

Higgs particles may get an upgrade from by-product to big player in the explanation of how the universe ended up with more matter than antimatter. They could also explain one possible way dark matter was made.

Cellular transport research wins Nobel Prize in medicine or physiology

Research on vesicle transport has won the Nobel Prize in medicine or physiology.  

Three men will share the honor for their work describing how small membrane bubbles loaded with molecules get sorted to the correct part of the cell. Shuttling of vesicles is necessary to move resources around cells. Determining the machinery involved in such transport and how it is controlled has led to a better understanding of brain signaling, hormone release and immune system function.
