Ridges on Mars have variety of origins, says new research

Ridges on Mars have variety of origins, says new research

Ridges of various sizes have been located in many regions of the Martian surface, and scientists surmise that they originated in a variety of processes and events. Laura Kerber of NASA’s Jet Propulsion Laboratory conducted a detailed search for these ridges after discovering a network of polygon-shaped features in Medusae Fossae, a location close to Mars’ equator. The ridges of ... Read More »

Physicists finally turn hydrogen into a metal

Physicists finally turn hydrogen into a metal

Scientists have been trying to turn hydrogen into metal for the past 80 years. Now they may have actually done it, or so a team of scientists at Harvard University claim. Thomas D. Cabot Professor of the Natural Sciences Isaac Silvera and postdoctoral fellow Ranga Dias have long sought the material, called atomic metallic hydrogen. In addition to helping scientists answer ...

New NASA video visualizes landing on Pluto “Watch”

New NASA video visualizes landing on Pluto (Watch)

A new video from NASA allows space enthusiasts to land on Pluto, all without leaving their couch. It was in July 2015 that the New Horizons probe whizzed by Pluto, revealing an extensive catalogue of images and details of the dwarf planet that had never been seen up until that point. Most notably, the scientific community and the general public ... Read More »

Assessing the impact of hydraulic fracturing on aquatic animals

Assessing the impact of hydraulic fracturing on aquatic animals

Scientists at the University of Alberta have conducted the first-ever study to use hydraulic fracturing fluids to examine effects on aquatic animals, such as rainbow trout. Horizontal drilling with high-volume hydraulic fracturing is a practice used globally for extracting oil and gas from tight reservoirs. Hydraulic fracturing uses large quantities of water and poses many environmental hazards in water, from ... Read More »

Opportunity rover marks Thirteen years on Mars (Video)

Opportunity rover marks Thirteen years on Mars (Video)

To celebrate the robot’s birthday, NASA/JPL made this charmingly dorky video that outlines all the ways Opportunity has become teenager-like, which mostly has to do with increased autonomy, overconfidence, and a compulsion to send pictures electronically at all times. The golf-cart-size Opportunity rover landed on Mars on the night of Jan. 24, 2004, a few weeks after its twin, Spirit, ... Read More »

TSRI researchers make a viable semi-synthetic organism

TSRI researchers make a viable semi-synthetic organism

A team of researchers from the Scripps Research Institute in La Jolla, California have created a lab organism that has been modified to add two more letters, giving it a genetic code of six letters. The team, whose work is published in the Proceedings of the National Academy of Sciences (PNAS) journal, have shown that their single-celled organism can hold ... Read More »

Researchers activate ‘kill switch’ in mice (Video)

Researchers activate 'kill switch' in mice

The origin of hunting behavior may come from two sets of neurons tucked deep in the forebrain of most vertebrates, a new Yale University research suggests. Activating these neurons in living mice prompt them to pursue never-seen-before prey and to bite everything in their path, even sticks and bottle caps, the researchers report in the Jan. 12 issue of the ...

New weather GOES-16 satellite sends back first images

New weather GOES-16 satellite sends back first images

The spectacular first images from NOAA’s powerful new GOES-16 satellite were released Monday, providing the most vivid look yet at our hemisphere from a geostationary weather satellite. The pictures from its Advanced Baseline Imager (ABI) instrument, built by Harris Corporation, show a full-disc view of the Western Hemisphere in high detail — at four times the image resolution of existing ...

Lone Zebra Shark Surprises Aquarium With Rare ‘Virgin Birth’ (Video)

Lone zebra shark surprises researchers with pups

A female zebra shark named Leonie in Australia has shocked scientists by producing three offspring after spending years away from her male partner. Subsequent analysis found that she had simply developed the ability to do it all on her own.. Researchers with Australia’s University of Queensland (UQ) observed the change at the Reef HQ Aquarium and have documented it in ... Read More »
