Astronomers have discovered a series of unusual globular star clusters with masses far exceeding what would be expected under the standard model for the celestial structures. The clusters are located in the giant elliptical galaxy Centaurus A, and seem to hint at an enigmatic dark presence that cannot yet be accounted for.
The results from a new NASA experiment suggest that the dark material seen coating geological features on Europa may well be sea salt. Originating from a subsurface ocean, the material is thought to have been discolored by exposure to radiation.
Great news if you're planning a visit to exoplanets Kepler-7b or HAT-P-7b. An international team of astrophysicists has identified daily weather cycles using Kepler telescope data on these and four other far off worlds. The nightly news isn't about to start reading extrasolar weather reports, but this new knowledge will help improve our understanding of the Earth's place in the cosmic puzzle.
Following the recent loss of the Russian Progress 59 cargo ship, NASA and its partners in the station have agreed to reshuffle future launches based on preliminary investigations by the Russian Federal Space Agency.
NASA's imaginatively-named Space Launch System (SLS), has entered its critical design
review phase, which will see the leviathan rocket given the go-ahead
for full-scale construction. The review represents a major milestone
that must be passed with flying colors if the SLS is to make its
intended maiden launch date, which is currently slated for 2017.
If you’re into electronics as
a hobbyist, technician, or professional engineer, you know that you can spend
many hours designing circuits, sourcing components, and breadboarding or
soldering a project all together before you find out if your creation actually works. Wouldn’t
it make life simpler if you could just start with a basic, multi-function
controller and a few plug and play peripherals to get something – anything – up
and running straight away and then which you could tweak and add to as you go?
The makers of a new electronic design tool thought that this would be a good
idea too and have created Cubit, a make anything platform that allows drag and
drop software control over snap together hardware. Join Gizmag as we try a few builds to test out it out.
If you happen to be frolicking around in some tropical waters at some point in the future, you may have the marine life circling your feet to thank for keeping your shoulders from roasting. Scientists have uncovered a technique used by zebrafish and various other animals to create their own sunscreen and recreated it in the lab. They say the method could one day be used to produce sunscreen and other pharmaceuticals for humans.
If you're like a lot of phone junkies and replace your phone as soon as the latest thing comes along, you'll know that often the hardware in the old phone is perfectly fine, even the battery. But fancier new screens and more powerful processors mean that battery life usually remains a problem, making battery packs a popular accessory. Enlighten's Better Re lets you get some more use out of your old phone's battery, by allowing it to slot into an adjustable external battery charger for your new phone.
We frequently hear that eating fish is a healthy thing to do, because
it's full of beneficial long chain fatty acids. Unfortunately, the
Western diet tends to be short on fish and bigger on beef, which
contains short chain fatty acids that aren't quite so good for us.
Chinese scientists are creating a work-around, however –
genetically-engineered beef that's high in the "good" fatty acids.
Using a matrix of nano-sized memristors, researchers
working at the Royal Melbourne Institute of Technology (RMIT) and the
University of California, Santa Barbara claim to have constructed the world’s
first electronic memory cell that effectively mimics the analog process of the
human brain. By storing memories as multiple threads of varying information,
rather than a collection of ones and zeroes, scientists believe that this
device may prove to be the first step towards creating a completely artificial,
