Self-organizing smart materials that mimic swarm behavior

A new study by an international team of researchers, affiliated with Ulsan National Institute of Science and Technology (UNIST) has announced that they have succeeded in demonstarting control over the interactions occurring among microscopic spheres, which cause them to self-propel into swarms, chains, and clusters.

RMIT researchers make leap in measuring quantum states

A breakthrough into the full characterisation of quantum states has been published today as a prestigious Editors' Suggestion in the journal Physical Review Letters.

The full characterisation (tomography) of quantum states is a necessity for future quantum computing. However, standard techniques are inadequate for the large quantum bit-strings necessary in full scale quantum computers.

Hospital more than 4 times as likely for under-6s after laundry pod detergent contact

Children under the age of 6 are four times as likely to end up in hospital after contact with laundry pod detergent as children exposed to other types of detergent, finds research published online in the journal Injury Prevention.

Nearly three out of four cases were diagnosed as poisoning compared with a similar proportion diagnosed as contact dermatitis for loose liquid or powder detergents, the findings show.

The researchers base their findings on national US data from emergency department visits for children under the age of 5 between 2012 and 2014.

Scientists unlock 'green' energy from garden grass

Garden grass could become a source of cheap and clean renewable energy, scientists have claimed.

A team of UK researchers, including experts from Cardiff University's Cardiff Catalysis Institute, have shown that significant amounts of hydrogen can be unlocked from fescue grass with the help of sunlight and a cheap catalyst.

Research offers new hope for understanding deadly infections

LOS ANGELES -- Research published today in the journal, Nature Communications, provides new insights into the evolution of Mucorales fungi, which cause a fatal infection in ever-increasing segments of patient population, and several molecular pathways that might be exploited as potential therapeutic or diagnostic targets.

Three Alzheimer's genetic risk factors linked to immune cell dysfunction

People with a variant copy of the TREM2 gene have an increased risk of developing Alzheimer's disease, but researchers are only beginning to understand why.

How water collector bees know when to quench hot hive's thirst

Thirst is a sensation that we can all relate to; however, dealing with this basic physiological impulse takes on a whole new dimension when an entire bee colony craves water. 'We are interested in the social physiology of honey bee colonies, that is, how they work as physiological units', says Thomas Seeley, from Cornell University, USA, who was curious how the elderly bees that are tasked with gathering water know when the colony's collective thirst is running high.

Underwater terrain may be key factor in little auk foraging

Little auks forage in the same areas off East Greenland--the continental shelf and its edge--regardless of whether sea ice is present or absent, according to a study published July 20, 2016 in the open-access journal PLOS ONE by Françoise Amélineau, from the University of Montpellier, France, and colleagues.

New dinosaur species may give clues to evolutionary origin of megaraptorid clade

A new species of megaraptorid dinosaur discovered in Patagonia may help discern the evolutionary origins of the megaraptorid clade, according to a study published July 20, 2016 in the open-access journal PLOS ONE by Rodolfo Coria from the Consejo Nacional de Investigaciones Científicas y Técnicas, Argentina, and Phillip Currie from the University of Alberta, Canada.

Hormone therapy for brain performance: No effect, whether started early or late

A study led by a scientist at the Stanford University School of Medicine shows that hormone therapy has a negligible effect on verbal memory and other mental skills regardless of how soon after menopause a woman begins therapy.

The study is the first large, long-term clinical trial to compare the effects of estradiol, a type of estrogen, on the mental capabilities of women who commence treatment soon after menopause versus those who begin after a long delay.

Harvesting water from air with less energy

Getting clean water to communities in parched areas of the planet remains an ongoing challenge. Recent developments that harvest water from air have been proposed as a solution. However, the technology to do so consumes a lot of energy. But based on new modeling results, scientists now report in ACS' journal Environmental Science & Technology that a new system design would require less energy and produce high-quality water.

CDC scientists review methods to prevent bites and suppress ticks that transmit Lyme disease

Dr. Lars Eisen and Marc Dolan of the U.S. Centers for Disease Control and Prevention have reviewed decades of scientific literature on the effectiveness of various methods of preventing bites and controlling ticks that transmit Lyme disease. Their findings are published in the Journal of Medical Entomology.

To protect yourself from malaria sleep with a chicken next to your bed

For the first time, scientists have shown that malaria-transmitting mosquitoes actively avoid feeding on certain animal species such as chickens, using their sense of smell. Odors emitted by species such as chickens could provide protection for humans at risk of mosquito-transmitted diseases, according to a study in the open access Malaria Journal.

Anti-tumor antibodies could counter atherosclerosis, Stanford study finds

Investigators at the Stanford University School of Medicine have learned the signal that tumor cells display on their surfaces to protect themselves from being devoured by the immune system also plays a role in enabling atherosclerosis, the process underlying heart attacks and strokes.

How cells master the art of reading life's recipes

A research project led by The Australian National University (ANU) has closed an important gap in the understanding of a fundamental process of life - the creation of proteins based on recipes called RNA.

RNAs are short-lived copies of genetic information stored in DNA. They are read by cellular ribosomes, which translate the recipes into proteins to become the main building blocks of life.
