Massive Mars dust storm could offer clues to planet’s dryness
The ExoMars Trace Gas Orbiter’s observations of the massive dust storm that enveloped Mars last year may help researchers learn more about what happened to the planet’s water. Understanding how […]

Galaxy collisions can sometimes eject supermassive black holes
Researchers are on the lookout for supermassive black holes that ended up off-center or got kicked out of their galaxies completely when galaxies merged. The European Space Agency’s launch of its Laser […]

How neural network guides autonomous car’s turns
An autonomous car was trained to negotiate high-speed turns without losing control. A neural network based on more than 200,000 motion samples of driving on various surfaces at high speeds was used in […]

Sun bears communicate via facial mimicry
Sun bears communicate by mimicking each other’s facial expressions, a practice long thought to occur only in species with complex social systems. “Other primates and dogs are known to mimic each other, but only […]

Hormonal birth control failure might be due to genetic mutation
The reason hormonal birth control methods aren’t 100% effective, even in compliant patients, may be due to a genetic mutation in some women. Researchers say about 5% of women are […]

Photo captures merging shock waves made by jets
Merging shock waves created by the supersonic speeds of two Air Force jets can be seen for the first time in photos taken by NASA. A plane flying over the two T-38 […]

Ocean warming threatens fish populations
Warming ocean temperatures due to climate change helped reduce the amount of seafood that could be sustainably caught between 1930 and 2010 by 4.1% worldwide. In some regions, such as the Sea of Japan and […]

Large-scale testing of biotech mosquitoes begins
Italy-based scientists have begun large-scale testing of biotech mosquitoes in a controlled laboratory that mimics their natural environment. The biotech mosquitoes have the doublesex gene mutation, resulting in malformed reproductive organs that prevent female […]

Mode of delivery may affect breast milk’s bacterial composition
Canadian researchers found that pumped breast milk had reduced levels of healthy bifidobacteria and elevated levels of some infection-causing bacteria, such as Pseudomonadaceae and Stenotrophomonas, compared with directly breastfed milk.
Health […]

Reef fish may know it’s seeing its reflection in mirror
A coral reef fish may be able to recognize itself in a mirror. After researchers injected a colored dye on the throats of bluestreak cleaner wrasses and placed them in […]
