Graphene sieve turns seawater into drinking water Posted: 03 Apr 2017 04:31 PM PDT Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.

Prehistoric art and ornaments from Indonesian 'Ice Age' Posted: 03 Apr 2017 12:11 PM PDT A joint Indonesian-Australian team has unearthed a rare collection of prehistoric art and 'jewellery' objects from the Indonesian island of Sulawesi, dating in some instances to as early as 30,000 years ago.

Android apps can conspire to mine information from your smartphone Posted: 03 Apr 2017 12:11 PM PDT Mobile phones have increasingly become the repository for the details that drive our everyday lives. But researchers have recently discovered that the same apps we regularly use on our phones to organize lunch dates, make convenient online purchases, and communicate the most intimate details of our existence have secretly been colluding to mine our information.

Monkey business produces rare preserved blood in amber fossils Posted: 03 Apr 2017 12:11 PM PDT Two monkeys grooming each other about 20-30 million years ago may have helped produce a remarkable new find - the first fossilized red blood cells from a mammal, preserved so perfectly in amber that they appear to have been prepared for display in a laboratory.

Electronic synapses that can learn: Towards an artificial brain? Posted: 03 Apr 2017 11:02 AM PDT Researchers have created an artificial synapse capable of learning autonomously. They were also able to model the device, which is essential for developing more complex circuits.

New indications of gradual decline of dinosaurs before the end of the cretaceous period Posted: 03 Apr 2017 10:59 AM PDT The gradual decline of the dinosaurs and pterosaurs presumably came before the impact of the Chicxulub asteroid and the global mass extinction at the end of the Cretaceous Period, new research suggests. Studies also indicate that bird species spread and diversified at the same time the dinosaurs disappeared.

Mutant lifestyles: Researchers uncover a potent genetic element in Earth's smallest life forms Posted: 03 Apr 2017 10:55 AM PDT A potent genetic element has been uncovered in Earth's smallest life forms. A multitude of previously unidentified microorganisms possess a genetic element that enables them to self-mutate.

Spray-on memory could enable bendable digital storage Posted: 03 Apr 2017 10:54 AM PDT Researchers have created a new 'spray-on' digital memory using only an aerosol jet printer and nanoparticle ink. The device, which is analogous to a 4-bit flash drive, is the first fully-printed digital memory suitable for practical use in simple electronics such as environmental sensors or RFID tags. Because it is jet-printed, it could be used to build programmable electronic devices on flexible materials like paper, plastic or fabric.

Man moves paralyzed legs using device that stimulates spinal cord Posted: 03 Apr 2017 09:36 AM PDT Electrical stimulation was used on the spinal cord of a patient in a new study, and combined with intense physical therapy, the man intentionally moved his paralyzed legs, stood and made steplike motions for the first time in three years.

Stretching the boundaries of neural implants Posted: 03 Apr 2017 09:35 AM PDT New nanowire-coated, stretchy, multifunction fibers can be used to stimulate and monitor the spinal cord while subjects are in motion, researchers report.

Surprise discovery of Europe's first cave fish Posted: 03 Apr 2017 09:35 AM PDT Researchers have discovered the first European cave fish. A hobby cave diver first sighted the fish, a loach in the genus Barbatula, living in a hard-to-reach, underground water system in South Germany.

Magnetic brain stimulation causes weight loss by making gut bacteria healthier Posted: 03 Apr 2017 09:35 AM PDT A new study finds that a noninvasive electromagnetic brain stimulation technique helps obese people lose weight, partly by changing the composition of their intestinal bacteria -- the so-called gut microbiota.

Nanoscopic golden springs change color of twisted light Posted: 03 Apr 2017 09:35 AM PDT Scientists have used gold spring-shaped coils 5,000 times thinner than human hairs with powerful lasers to enable the detection of twisted molecules, and the applications could improve pharmaceutical design, telecommunications and nanorobotics.

How melanoma tumors form Posted: 03 Apr 2017 09:33 AM PDT Researchers have documented in continuous, real time how melanoma cells form tumors. The team report the process is similar to that of breast cancer cells and have successfully screened for two antibodies that stopped tumor formation in both cancers.

Early life antibiotic use linked to inflammatory gut diseases in adulthood Posted: 03 Apr 2017 09:33 AM PDT A new research report involving mice shows that antibiotic use very early in life that alters the normal development/growth of gut bacteria, may contribute to the development of inflammatory bowel disease, and potentially other inflammatory diseases like asthma and multiple sclerosis.

Babies cry most in UK, Canada, Italy, Netherlands Posted: 03 Apr 2017 05:30 AM PDT Psychologists have created world's first universal charts for normal amount of crying in babies during first three months. On average, babies around the world cry for around 2 hours per day in first two weeks, peak at 2 hours 15 mins at six weeks -- and crying reduces to 1 hour 10 minutes by week twelve. Their study found that babies cry more in Britain, Canada and Italy, than the rest of the world, according to new research. In Denmark, Germany and Japan, parents deal with the least amount of crying and fussing.

Harms of nighttime light exposure passed to offspring Posted: 31 Mar 2017 09:03 AM PDT Animals can pass the damaging effects of nighttime light exposure to their offspring, a new study has found, adding to a growing body of evidence that there's a health cost to our increasingly illuminated nights.

Is it a boy or is it a girl? New method to ID baby sea turtles' sex Posted: 30 Mar 2017 06:28 AM PDT Is it a boy or is it a girl? For baby sea turtles it's not that cut and dry. Because they don't have an X or Y chromosome, baby sea turtles' sex is defined during development by the incubation environment. Warmer sand temperatures produce more females and cooler sand temperatures produce more males. A crucial step in the conservation of these animals is estimating hatchling sex ratios, which remains imprecise because of their anatomical makeup.

Shadow of agas cloud detected in an ancient proto-supercluster Posted: 29 Mar 2017 07:37 AM PDT The Suprime-Cam on the Subaru Telescope has been used to create the most-extensive map of neutral hydrogen gas in the early universe. This cloud appears widely spread out across 160 million light-years in and around a structure called the proto-supercluster. It is the largest structure in the distant universe, and existed some 11.5 billion years ago. Such a huge gas cloud is extremely valuable for studying large-scale structure formation and the evolution of galaxies from gas in the early universe, and merits further investigation.
