A molecular light switch?... Just add water

A bit of stray moisture during an experiment tipped off scientists about the strange behavior of a complex oxide material they were studying—shedding light on its potential for improving chemical sensors, computing and information storage. In the presence of a water molecule on its surface, the layered material emits ultraviolet light from its interior. A team of researchers from Drexel University, the University of Pennsylvania, the University of California at Berkeley, and Temple University recently published its discovery that it is possible to control UV light production via a chemical reaction that functions like flipping a light switch.

Solar cells that can face almost any direction and keep themselves clean

In recent years, a complicated discussion over which direction solar cells should face—south or west—has likely left customers uncertain about the best way to orient their panels. Now researchers are attempting to resolve this issue by developing solar cells that can harvest light from almost any angle, and the panels self-clean to boot. Their report appears in the journal ACS Nano.

Clues on the development of magnetic sensors with pure spin current

"Spintronics" is a new class of electronics where charge and spin are utilized. A pure spin current, flow of spin without charge current, is one of the important physical quantities in its field, which could play an essential role in low energy consumption electronics of the next generation.A group of researchers in Japan and France succeeded in detecting magnetic fluctuations with pure spin current in a much more sensitive way than conventional magnetization measurements. 

Time-resolved measurement of the anomalous velocity

The movement of charge carriers perpendicular to an electric driving field – even without a magnetic field – constitutes one of the most intriguing properties of carriers in solids. This anomalous velocity is at the origin of fascinating physical phenomena – with the spin Hall effect and the anomalous Hall effect being two prominent examples – and might be important for future spintronic applications or even new quantum computers. At PTB, researchers have now succeeded in detecting the anomalous velocity in a semiconductor made of GaAs with a sub-picosecond time resolution. On the one hand, this work gives new insight into the microscopic origins of the anomalous velocity. On the other hand, it opens a new area of research for studying important physical effects on ultrafast time scales.

Team reveals the physics for the mechanism of slow change in microscopic magnetic structures

The research group of Professor Hideo Ohno and Associate Professor Shunsuke Fukami of Tohoku University has studied in detail, a slow change of microscopic magnetic structures in metallic wires induced by external driving forces, commonly called "creep" motion. This has allowed them to clarify the physics of how the driving forces, magnetic fields or electric currents, act on the magnetic structure.

What are the parts of an atom?

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of four or five elements – earth, air, water, fire (and metal, or consciousness) – by classical antiquity, philosophers began to theorize that all matter was actually made up of tiny, invisible, and indivisible atoms.

The amount of snowfall in coastal West Antarctica increased during the 20th century

The Amundsen Sea sector of the West Antarctic Ice Sheet has been losing mass in recent decades. However, long records of snow accumulation are needed to place the recent changes in context. In this paper we present 300-year records of snow accumulation from two ice cores drilled in Ellsworth Land, West Antarctica. The records show a dramatic increase in snow accumulation during the twentieth century, which has been linked to a deepening of surface pressure in the Amundsen Sea, a feature known as the Amundsen Sea Low. The persistent climatological low pressure system, indicating increased storm activity, draws warm, maritime air from the mid-latitudes to the Amundsen Sea coast. The increased snowfall is also linked to tropical sea-surface temperatures and a reduction in sea ice in the Bellingshausen Sea, resulting in greater moisture availability.

The drive towards ethical AI and responsible robots has begun

Roboticist Sabine Hauert, from the Britain's University of Bristol, wrote in Nature earlier this year:

No aircraft is too small to kill – fitting flight recorders could prevent further deaths

When a police helicopter plunged into the Clutha pub in Glasgow city centre two years ago, killing ten, an accident investigation was launched to find out what happened and why – a process that is essential to preventing future accidents and loss of life. But smaller aircraft are not required to carry flight data recorders – the black box so vital to air crash investigations. So while the recently published report into the crash revealed some of the reasons behind, there were details – potentially vital details – that couldn't be known because they weren't recorded. It's about time this changed.

Skewed expression of mRNA components correlates with fine tuning of protein production

Long cast as a simple link between DNA and protein, messenger RNA has never offered much intrigue. But new research at The Rockefeller University suggests the molecule is up to something unexpected.

Plants crawled onto land earlier than we give them credit, genetic evidence suggests

Plant biologists agree that it all began with green algae. At some point in our planet's history, the common ancestor of trees, ferns, and flowers developed an alternating life cycle—presumably allowing their offspring to float inland and conquer Earth. But on December 16 in Trends in Plant Science, Danish scientists argue that some green algae had been hanging out on land hundreds of millions of years before this adaptation and that land plants actually evolved from terrestrial, not aquatic, algae.

Big moves in protein structure prediction and design

The potential of modular design for brand new proteins that do not exist in the natural world is explored Dec. 16 in the journal Nature. The reports are the latest in a recent series of developments toward custom-designing proteins.

New twist in tale of dogs' origins

The origin of dogs has inspired a lingering controversy in academia. Where and when did dogs first split off from wolves? One of the top dogs in this dispute, population genetics expert Peter Savolainen of Sweden's KTH Royal Institute of Technology, isn't about to roll over. He hopes his latest research will finally settle the matter.

The double life of a bacteria—living off both iron and pure electricity

Researchers at the RIKEN Center for Sustainable Resource Science and the University of Tokyo have demonstrated that the bacterium Acidithiobacillus ferrooxidans can take electrons needed for growth directly from an electrode power source when iron—its already known source of energy—is absent. The study, published in Frontiers in Microbiology, shows that A. ferrooxidans can use direct uptake of electrons from an electrode to fuel the same metabolic pathway that is activated by the oxidation of diffusible iron ions.

Researchers uncover multiple adaptations to temperature in birds and mammals

Understanding the different ways organisms can adapt to environmental temperatures is central to understanding how they will respond to climate change.

Western Australia's rarest bird species headed for extinction

One of the last known populations of WA's rarest bird species is tipped to disappear from a global biodiversity hotspot unless action is taken to address climate change.

West Coast marine mammals respond to shifting conditions, new research shows

Humpback whales off the West Coast consume thousands of pounds of krill, plankton and small fish each day. Research shows that humpback diets reflect their surroundings, with the truck-sized whales filter-feeding on vast amounts of krill when cold upwelling waters prevail, but switching to schooling fish such as anchovies when warmer waters take over and the fish grow abundant.

Dogs give friends food

Compared to the rest of the animal kingdom, the human capacity for cooperation is something quite special. Cooperating with one another requires a certain amount of prosocial behaviour. This means helping others without any direct personal benefit.

Three new fishing snake species fished out of the Andean slopes in South America

Commonly known as fishing snakes, the Synophis genus has been expanded with as many as three new species following a research in the Andean cloud forests of Amazonian Ecuador and Peru. Not only is the discovery remarkable due to the rarity of new snake species being discovered, but also because this is the first time this mysterious and already eight-member genus is recorded from Peru. The study is published in the open-access journal ZooKeys.

Aphids balance their diets by rebuilding plant amino acids

Aphids suck up an almost endless supply of sugary sap from their plant hosts. They can survive on this junk food diet because bacterial partners help them convert the handful of amino acids in the sap into other, essential amino acids—not by recycling them, but by breaking them down and rebuilding from scratch, a new study finds.

Penguin cam captures hunt for prey

The findings are published in Psychological Science, a journal of the Association for Psychological Science.

To stop cancer's spread, take out its communication channels

Metastasis - or the spread of cancer from one part of the body to other parts - accounts for more than 90 percent of cancer-related deaths. Although the cells that seed metastasis and the sites that they tend to travel to have been increasingly studied over the years, little has been known about how cancer migrates from a primary site, such as breast tissue, to a secondary site, such as the brain or bone marrow. A study by researchers from Brigham and Women's Hospital (BWH), published in Nature Communications, offers a new view of how cancer cells extend their reach, co-opting and transforming normal cells through "metastatic hijacking." The researchers also find that in pre-clinical models, pharmacological intervention can prevent this hijacking from occurring, pointing to new therapeutic targets for preventing cancer cells from spreading.

Researchers elucidate network of genes that control when puberty begins

In expanding our knowledge of how the brain controls the process of sexual development, researchers at Oregon Healthy & Science University and the University of Pittsburgh have identified for the first time members of an elaborate superfamily of genes that regulate the timing of puberty in highly evolved nonhuman primates. The Zinc finger, or ZNF, gene family comprises approximately 800 individual genes.

Mitochondria, an exciting new target for the treatment of anxiety disorders

One third of patients with anxiety disorders do not respond to currently available anxiolytic treatments. In their latest study, scientists at the Max Planck Institute of Psychiatry in Munich have shown for the first time that manipulation of mitochondria exerts anxiolytic effects. This improved understanding of how mitochondrial changes affect anxiety may provide the key to novel treatments.

Unexpected molecular partners may offer new way to counter inflammatory diseases

When overactive or off target, certain cells in the immune system that normally fight infection instead attack a person's own tissue. This process fuels inflammation as part of autoimmune diseases. Now, a study from researchers at NYU Langone Medical Center publishing on December 16 in Nature has revealed a new way to curtail these mechanisms that could shape the design of future drugs.

Scientists reveal new phase of HIV infection

Researchers at the University of Massachusetts Medical School have identified a new life cycle stage in HIV infection, thanks to a novel technique they developed to take images of intact infected cells. They've shown that this phase of infection, dubbed intra-nuclear migration, by principal investigator Abraham L. Brass, MD, PhD, relies on the human protein CPSF6 to guide the virus through the host cell's nucleus and position it at active genes where it prefers to make its home. Details of HIV's intra-nuclear migration and the imaging techniques used to find it were published in Cell Reports.

How brain architecture leads to abstract thought

Using 20 years of functional magnetic resonance imaging (fMRI) data from tens of thousands of brain imaging experiments, computational neuroscientists Hava Siegelmann and a postdoctoral colleague at the University of Massachusetts have created a geometry-based method for massive data analysis to reach a new understanding of how thought arises from brain structure.

Implant acts as a countermeasure

ETH Professor Martin Fussenegger calls them molecular prosthetics: cells with specially developed gene circuits that can be implanted into an organism, where they take over metabolic functions that the organism cannot perform itself. Fussenegger and his team at ETH Zurich's Department of Biosystems Science and Engineering in Basel have now succeeded in developing a molecular prosthesis of this kind where the functions are far more complex than before. The prosthesis is tailored to the treatment of psoriasis, a complex and chronic inflammatory disease of the skin.

Scientists discover the function and connections of three cell types in the brain

How the brain functions is still a black box: scientists aren't even sure how many kinds of nerve cells exist in the brain. To know how the brain works, they need to know not only what types of nerve cells exist, but also how they work together. Researchers at the Salk Institute have gotten one step closer to unlocking this black box.

A new longitudinal study that examined an intervention for children at high risk of developing behavior problems has found that teaching so-called soft skills was key to preventing criminal and delinquent problems later in life. Soft skills, such as self-control and social skills, are personality traits, attitudes, and motivations not included in traditional measures of intelligence.

Children's ADHD symptoms and peer relationships influence each other over time

Children with attention deficit hyperactivity disorder (ADHD) are restless, inattentive, and impulsive, and they have difficulty with social functioning, often having fewer friends and being rejected more than children without ADHD. In a new longitudinal study from Norway, researchers investigated the bidirectional relationship between the development of ADHD symptoms in young children and rejection by peers.

Ethnic differences in CF genetic coding not addressed in screening tests for nonwhite patients

Cystic fibrosis (CF) occurs less frequently in nonwhites than in whites, and nonwhites tend to be diagnosed at a later age. This late diagnosis often comes only once they have become symptomatic, rather than through newborn screening programs or molecular diagnostic testing. Delaying diagnosis can result in postponed treatment and clinical deterioration. A new study in The Journal of Molecular Diagnostics found that one reason for this ethnic disparity in CF diagnoses is that the variants examined in the most common CF newborn screening panels do not sufficiently include the variants present in nonwhite populations.

Poverty may increase childhood risk of neurological impairment, study suggests

Children from low income environments appear to have a higher risk of neurological impairment than those from more economically secure circumstances, according to researchers at the National Institutes of Health and other institutions. This neurological impairment appears to be distinct from the risk of cognitive and emotional delays known to accompany early-life poverty.

Many unexpected genetic variants hamper personalised medicine

In recent decades much hope was based on the development of personalised drug treatments, in which genetic tests determine the choice and optimal dose of medication for each individual patient. However, the real breakthrough is still to be seen, and now researchers at Karolinska Institutet show in two separate scientific papers that many more gene variants affect how a person responds to medication than previously thought – and thus that today's analytical tools are too coarse.

New weapon in the fight against breast cancer

The first clinically-relevant mouse model of human breast cancer to successfully express functional estrogen receptor positive (ER+) adenocarcinomas has been developed by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab). The tumors generated in this system bear a striking resemblance to the class of tumors found in the vast majority of women with breast cancer, and especially to those whose cancer proves treatment-resistant. This model should be a powerful tool for testing therapies for aggressive ER+ breast cancers and for studying the biology and etiology of luminal cancers—the most prevalent and deadliest forms of breast cancer.

Filtering the blood to keep cancer in check

A new diagnostic system used to detect cancer cells in small blood samples could next be turned towards filtering a patient's entire system to remove those dangerous cells – like a dialysis machine for cancer – says an Australian researcher who helped develop the system.

A team of scientists, comprising researchers from the Institute of Molecular and Cell Biology (IMCB), a research institute under the Agency for Science, Technology and Research (A*STAR), Singapore, and the VIB Laboratory of Molecular Cancer Biology (VIB/KU Leuven), has revealed the mechanism by which tumor cells elevate levels of MDM4, a protein that is highly expressed in cancer cells but not in normal adult tissues. The team has also found that the mechanism can be interfered with antisense oligonucleotides (ASOs) to suppress cancer growth. The study which paves the way for the development of novel cancer therapeutics was published in the leading Journal of Clinical Investigation (JCI).

Researchers find a compound helping to regenerate neurons in damaged areas of the brain

Many neurology pathologies cause irreversible loss of neurons. They are mostly the so-called neurodegenerative diseases although there exist other causes for a focal loss of neurons, as it is the case in strokes or traumatic brain injuries. All these pathologies lack nowadays of an efficient treatment not being possible to regenerate dead neurons. In fact, although the brain has the ability to regenerate as many studies has proved, this regeneration is very low, ranging from 0.2% to a maximum of 10% depending on the type of injury and the damaged area.

Fat-burning fat exists, but might not be the key to weight loss

Researchers find out cause of mutations which are not in genetic material

Proteins are like bricks that form our cells and they are built by the orders given by our genetic material, DNA. In human diseases, eventually DNA alterations modify proteins and they don't do their normal function, either by excess or defect. But recently we have started to find alterations of proteins without an obvious damage of the gene that produces them.

Minding the gap: International team defines spaces through which nerve cells communicate

In a report published in the journal Neuron, an international team of researchers defined the makeup of the cellular structures through which nerve cells communicate with each other. These "synaptic clefts" are the small gaps between nerve cells (neurons) that relay information in the brain. Synapses, including the synaptic clefts, are formed rapidly shortly before and after birth. Mutations in the proteins that make up the cleft increase vulnerability to developmental disorders, notably autism spectrum disorders.

When disaster strikes

Behind makeshift orange fencing, the Ebola isolation unit in Bo, Sierra Leone, lies shrouded in a haze of smoke from the constant fires burning contaminated bedding and clothing. UC San Francisco physician Andrea Tenner, MD, MPH, looking like an astronaut in a head-to-toe protective suit, peers through foggy goggles as she reviews duty lists with local colleagues before entering the hot zone – the testing ward for patients with possible Ebola virus infection. She weaves her way through the labyrinth of protective barriers, ending up in the suspect ward, where patients who've exhibited Ebola symptoms anxiously await their test results.

Police-related killings are countable public health data

What is the purpose of public health? Public health is a societal approach to protecting and improving the health and well-being of populations. Rather than focus on the health of individuals – that's medicine – public health practitioners identify and address system-level influences on the health of overall populations. Issues such as clean water supplies, school vaccination programs, and public smoking bylaws all fall in the domain of public health. Social justice is often, and should always be, an overarching focus of public health campaigns. The aim to improve the health of populations means all people in the population, however the 'population' is defined. To protect and improve everyone's health often means different strategies for different segments of the population. Specific 'at-risk' or 'vulnerable' groups are those who face the largest societal burden of ill health through adverse living conditions, and who often ha! ve insufficient financial or social means to avoid health risks.
