A bank specializing in bitcoins says it has closed after computer hackers robbed its digital currency. The closure of the Flexcoin bank comes just a week after the collapse of Mt. Gox, a major bitcoin exchange. Mt. Gox also linked its demise to an electronic heist. In a Tuesday notice, Flexcoin...
An info-war is under way as websites are blocked and telecom cables to Crimea are mysteriously cut. Russia’s takeover of the Crimean peninsula has been accompanied by a elements of an information-control campaign: Telecom cables connecting that region to the rest of Ukraine have been severed....
In a talk before a packed audience at the Connecticut Mental Health Center auditorium, Susannah Cahalan, New York Post journalist and author of “Brain on Fire: My Month of Madness,” recalled her psychological deterioration and her journey to find a correct diagnosis.
If you like sinister Facebook conspiracy theories, a report today from the news blog TechCrunch provides you with a real doozy. Facebook is reportedly in serious talks to acquire a drone company called Titan Aerospace. The company makes solar-powered drones...
A new twist on a very old physics technique could have a profound impact on one of the most buzzed-about aspects of nanoscience. Researchers at the University of Cincinnati have found that their unique method of light-matter interaction analysis appears to be a good way of helping make better semiconductor nanowires.
This new Hubble image shows ESO 137-001, a galaxy located in the southern constellation of Triangulum Australe (The Southern Triangle) — a delicate and beautiful spiral galaxy, but with a secret. This image not only captures the galaxy and its backdrop in stunning detail, but also something more dramatic — intense blue streaks streaming outwards from the galaxy, seen shining brightly in ultraviolet light.
A new chemical synthesis for α-arylated Carbonyl derivatives was developed. Members of this class of substances typically possess interesting biological and pharmacological properties and often find applications as medicines. The new technique, which allows Carbonyl derivatives to be generated easily, efficiently and in an environmentally friendly manner– without wasting any atoms –has raised significant scientific interest and awareness.
Astronomers at the University of Washington have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, scientists may one day use this same technique to detect its biosignature — the telltale chemical signs of its presence — in the atmosphere of an alien world.
Since the dawn of the Bronze Age, people have appreciated the advantages of using alloys rather than single metals to make better materials. Recently, scientists have discovered a recipe for making tiny two-metal structures that could similarly expand the forefront of materials science.
Roku is getting into an Internet video-streaming stick fight with Google's Chromecast. Like the similarly shaped Chromecast, Roku's thumb-sized device plugs into a TV's HDMI port and feeds Internet video through a Wi-Fi connection. The Roku device, announced Tuesday, sells for $50 compared with...
In physics, there's small, and then there's nullity – as in zero-dimensional. University of Cincinnati researchers have reached this threshold with a special structure that may someday lead to better ways of harnessing solar energy, stronger lasers or more sensitive medical diagnostic devices.These structures are semiconductor nanowires.
Researchers at Harvard's Wyss Institute have developed a method to carry out large-scale manufacturing of everyday objects – from cell phones to food containers and toys – using a fully degradable bioplastic isolated from shrimp shells. The objects exhibit many of the same properties as those created with synthetic plastics, but without the environmental threat.
Middle-aged adults who suddenly need reading glasses, patients with traumatic brain injuries, and people with visual disorders such as "lazy eye" may have one thing in common. Visual crowding makes it impossible to read, as single letters within words are rendered illegible. And basic cognitive functions can also be significantly hampered. Scientists and clinicians currently attribute crowding to a disorder in peripheral vision.
Exposing leafy vegetables grown during spaceflight to a few bright pulses of light daily could increase the amount of eye-protecting nutrients produced by the plants, according to a new study by researchers at the University of Colorado Boulder.
a person suffers a broken bone, treatment calls for the surgeon to insert screws and plates to help bond the broken sections and enable the fracture to heal. But metal devices may have disadvantages: Because they are stiff and unyielding, they can cause stress to underlying bone. Now, using pure silk protein derived from silkworm cocoons, investigators developed surgical plates and screws.
