Russian physicists discover a new approach for building quantum computers

Physicists from MIPT and the Russian Quantum Center have developed a method which is going to make it easier to create a universal quantum computer -- they have discovered a way of using multilevel quantum systems (qudits), each one of which is able to work with multiple "conventional" quantum elements -- qubits.

Lack of sleep increases a child's risk for emotional disorders later

HOUSTON, July 21, 2016 - When asked how lack of sleep affects emotions, common responses are usually grumpy, foggy and short-tempered. While many jokes are made about how sleep deprivation turns the nicest of people into a Jekyll and Hyde, not getting enough shut-eye can lead to far more serious consequences than irritability, difficulty concentrating and impatience.

Three-drug combinations could help counter antibiotic resistance, UCLA biologists report

Three-drug combinations could help counter antibiotic resistance, UCLA biologists report

Each year, approximately 700,000 people die from drug-resistant bacterial infections. A study by UCLA life scientists could be a major step toward combating drug-resistant infections.

The research, reported in the journal Royal Society Interface, found that combinations of three different antibiotics can often overcome bacteria's resistance to antibiotics, even when none of the three antibiotics on their own -- or even two of the three together -- is effective.

A new key to understanding molecular evolution in space

A new key to understanding molecular evolution in space

Scientists at Hokkaido University have revealed temperature-dependent energy-state conversion of molecular hydrogen on ice surfaces, suggesting the need for a reconsideration of molecular evolution theory.

Molecular hydrogen, the most abundant element in space, is created when two hydrogen atoms bond on minute floating ice particles. It has two energy states: ortho and para, depending on the direction of proton spins. Ortho-hydrogen converts to para-hydrogen on extremely low temperature ice particles, though its mechanism remained unclear.

Scientists release recommendations for building land in coastal Louisiana

Scientists release recommendations for building land in coastal Louisiana

Today, a team of leading scientists and community experts with decades of experience released key recommendations to maintain and build land in coastal Louisiana. Their recommendations focus on operating Mississippi River sediment diversions and consider the needs of communities, wildlife and fisheries.

Collective hum: Buzzing midges inspire new swarm theory

A team of researchers based in Israel and the US has found a mathematical resemblance between swarm dynamics and gravitational interactions. The study, which has just been published in the New Journal of Physics, could provide a big leap forward in understanding the mass movement of flying insects.

Mount Sinai researchers identify way to predict and prevent damage in donated kidneys

A multicenter team of researchers led by Barbara Murphy, MD, of the Icahn School of Medicine at Mount Sinai has identified a panel of genes which can help predict whether a transplanted kidney will later develop fibrosis, an injury which can cause the organ to fail. Their results were published in the July 21 edition of Lancet.

For whom the births (and worms) toll

Human childbirth is not only unpleasant, it's also assumed to take a toll on women's health, even while women have a greater life expectancy. A new study led by UC Santa Barbara researchers, however, finds that indigenous women in the Bolivian Amazon with some of the highest birth rates in the world today experience negligible health costs from their intense reproductive effort.

Why apnea patients are prone to suffer from glaucoma

Scientists at Hokkaido University have successfully measured the eye pressure of sleeping patients with obstructive sleep apnea syndrome for the first time, finding an unexpected correlation with glaucoma.

Glaucoma is thought to be a disease in which the optic nerve sustains damage due to increased eye pressure, resulting in a restricted visual field. In addition to strokes and cardiovascular disease such as heart attacks, people with obstructive sleep apnea syndrome (OSAS) are prone to suffer from glaucoma at a rate about 10 times higher than non-OSAS sufferers.

Novel compounds arrested epilepsy development in mice

New Orleans, LA - A team led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of LSU Health New Orleans' Neuroscience Center of Excellence, has developed neuroprotective compounds that may prevent the development of epilepsy. The findings will be published online in Scientific Reports, a Nature journal, on July 22, 2016.
