Developed to help scientists learn more about the complex nature of celestial objects, astronomical surveys have been cataloging the night sky since the beginning of the 20th century. The iPTF started searching the skies for certain types of stars and related phenomena in February. Since its inception, iPTF has been extremely successful in the early discovery and rapid follow-up studies of transients, and two recent papers by iPTF astronomers describe first-time detections.
Empathy? Surprising study shows that brains process the pain of villains more than the pain of people we like
A counterintuitive findings from a new study show that the part of the brain that is associated with empathizing with the pain of others is activated more strongly by watching the suffering of hateful people as opposed to likable people.
Researchers illustrate why the imminent peaking of global oil production is a threat to U.S. national and global economies and demonstrate in their new study which vulnerable sectors could put the entire US economy at risk when global oil production peaks.
Haitian teens, especially those who live in the country's rural areas, are among the poorest persons in the Western Hemisphere, but they are rich in their family relationships and strongly rooted in their own culture.
Stroke patients who participate in a cardiac rehabilitation program for six months make rapid gains in how far and fast they can walk, the use of weakened limbs and their ability to sit and stand.
A team of researchers used a novel astronomical survey software system -- the intermediate Palomar Transient Factory (iPTF) -- to link a new stripped-envelope supernova, named iPTF13bvn, to the star from which it exploded. The iPTF team also pinpointed the first afterglow of an explosion called a gamma-ray burst that was found by the Fermi satellite.
Scientists have discovered the earliest known complete nervous system exquisitely preserved in the fossilized remains of a never-before described creature that crawled or swam in the ocean 520 million years ago. The find solves a long-standing debate as to when the ancestors of chelicerates -- spiders and their kin -- made their first appearance and provides evidence that their biting mouthparts evolved from the claw-like appendages of a long-extinct group known as megacheirans.
Did our skeletons evolve for protection or for violence? The earliest vestiges of our skeleton are encountered in 500-million-year-old fossil fishes, some of which were armor-plated filter feeders, while others were naked predators with a face full of gruesome, vicious teeth.
Cell biologists and chemists reveal how viral DNA traffics in human cells. They have developed a new method to generate virus particles containing labeled viral DNA genomes. This allowed them to visualize, for the first time, single viral genomes in the cytoplasm and the nucleus by using fluorescence microscopy in regular or superresolution mode. The new findings enhance our understanding of how viral disease occurs, and how cells respond to infections.
Astronomers have shed new light on the rarest and brightest exploding stars ever discovered in the universe. Their research proposes that the brightest exploding stars, called super-luminous supernovae, are powered by magnetars -- small and incredibly dense neutron stars, with gigantic magnetic fields, that spin hundreds of times a second.
Examining 12 major types of cancer, scientists have identified 127 repeatedly mutated genes that appear to drive the development and progression of a range of tumors in the body. The discovery sets the stage for devising new diagnostic tools and more personalized cancer treatments.
the_newsbeagle writes "About four million people around the world have pacemakers implanted in their bodies, and those devices all got there the same way: surgeons sliced open their patients' shoulders and inserted the pulse-generating devices in the flesh near the heart, then attached tiny wires to the heart muscle. ... A device that just received approval in the EU seems to solve those problems. This tiny pacemaker is the first that doesn't require wires to bring the electrical signal to the heart muscle, because it's implanted inside the heart itself, and is hooked onto the inner wall of one of the heart's chambers. This is possible because the cylindrical device can be inserted and attached using a steerable catheter that's snaked up through the femoral artery."

First, the pylons of Sydney's monorail came tumbling down. Now, the Minnesota Zoo in Apple Valley, MN has shuttered its aging monorail for good.
The cause of a mysterious, long-lasting, superbright form of supernova may now have been discovered. These outbursts may be driven by the birth of magnetars, dead stars that rank among the most powerful magnets in the cosmos, researchers say.
Divers raised a chunk of the Chelyabinsk meteorite from the bottom of Russia's Lake Chebarkul on Wednesday. The coffee-table-size boulder is the largest fragment recovered so far from the Feb. 15 meteor explosion that injured more than 1,000 people.
Architect David Adjaye is building a $300 million museum in D.C., and offering a $300 chair that echoes is monumental design.
Various behavioral treatment options are helping to treat the sleeplessness experienced by American soldiers who have been deployed in recent military operations. A review of research has been done on deployment-related insomnia among military personnel and veterans, conducted since 2010.
Nerval's Lobster writes "This year's revelations about NSA surveillance have upended the idea that our data—any of it—is truly secure from prying eyes. That uncertainty has sparked the rise of several businesses with a simple proposition: you can send whatever you want via their online service (text, images, video), and that data will vaporize within seconds of the recipient opening it up. One of the most popular of those services is Snapchat, which allows users to take "Snaps" (i.e., videos or photos) that self-destruct a few seconds after the recipient opens them; that data also disappears from the company's servers. But is 'disappearing' data truly secure from prying eyes? Earlier this week, Snapchat admitted to a loophole in its schema that leaves Snaps open to viewing by law enforcement — provided the latter shows up at the company's front door with a warrant. Until a recipient opens a Snap, it's stored in the company's datacenter. In theory, law enforcement could request that Snapchat send it an unopened Snap. 'If we receive a search warrant from law enforcement for the contents of Snaps and those Snaps are still on our servers,' read an Oct. 14 posting on Snapchat's corporate blog, 'a federal law called the Electronic Communications Privacy Act (ECPA) obliges us to produce the Snaps to the requesting law enforcement agency.' Law-enforcement entities have hit Snapchat with 'about a dozen' search warrants for unopened Snaps since May 2013. 'Law enforcement requests sometimes require us to preserve Snaps for a time, like when law enforcement is determining whether to issue a search warrant for Snaps,' the blog continued. That surveillance could also go beyond unopened Snaps: Snapchat 'Stories,' or a cluster of Snaps, live on the company's servers for up to 24 hours and can be viewed multiple times, which broadens the window for law enforcement to poke its way in."
