Brilliant hard drive quality with magnetic field sensors made of diamond

Quantum mechanics is not only of high interest in fundamental research. The current progress in quantum technologies promises numerous innovations of industrial relevance, which will be transferred into the economy within the next five to ten years. Researchers from the Fraunhofer Institute for Applied Solid State Physics IAF, the University of Stuttgart, and the Max Planck Institute for Solid State Research are developing highly sensitive diamond probes as a basis for novel quantum sensors. These are able to characterize smallest magnetic fields with a spatial resolution in the nanometer range. In the future, these probes will be used for the analysis and inspection of magnetic storage media in order to identify defective hard drive segments and thus considerably reduce rejection rates and production costs. A further field of application could be the characterization of biological substances, e. g. proteins. The research program "NMR (Nuclear Magnetic Resonance) at the Nanoscale" was launched in 2016 and will be running over the next three years.

In a study with potentially major implications for the future treatment of autoimmunity and related conditions, scientists from the Perelman School of Medicine at the University of Pennsylvania have found a way to remove the subset of antibody-making cells that cause an autoimmune disease, without harming the rest of the immune system. The autoimmune disease the team studied is called pemphigus vulgaris (PV), a condition in which a patient's own immune cells attack a protein called desmoglein-3 (Dsg3) that normally adheres skin cells.

Harnessing an innate repair mechanism enhances the success of retinal transplantation

Regenerative therapies, based on cell replacement, hold promise for a wide range of age-related diseases, but efforts to bring the therapies to patients have not been very successful - in large part because the newly-derived replacement cells can't integrate efficiently into tissues affected by the ravages of aging. Publishing in Science, researchers at the Buck Institute harnessed a naturally-occurring and evolutionarily ancient anti-inflammatory mechanism that repaired the eye and significantly enhanced the success of retinal regenerative therapies in mice. The results could be particularly significant for chronic inflammatory diseases of the eye, including macular degeneration.

E-cigarette use among college students—helpful aid or risky enabler?

Electronic cigarette (e-cigarette) use continues to rise, and current data regarding use of e-cigarettes among college students are needed. The study, "Electronic Cigarette Use Among College Students: Links to Gender, Race/Ethnicity, Smoking, and Heavy Drinking" found in the Journal of American College Health connects e-cigarette use in colleges to high rates of alcohol consumption and other factors such as: gender, race/ethnicity and traditional cigarettes. The rise of e-cigarettes may be a positive consequence of cigarette smokers who use this product to quit smoking or to avoid the toxicity of traditional cigarettes. However, e-cigarette use does not always reflect an attempt to reduce cigarette smoking and may instead indicate a general propensity to use psychoactive substances, especially among emerging adults.

Bioinformatics software is developed to predict the effect of cancer-associated mutations

Media not the scapegoat when it comes to teen sex

Parents and society in general shouldn't shift the blame for young people's sexual behavior on what teens supposedly see and read in the media about intimate encounters. Proclaiming a link between such so-called sexy media and the sexual behavior of young people is in fact premature. The media neither contributes to the early initiation of sex among young people, nor to their sexual conduct more generally. So says Christopher Ferguson of Stetson University in the US, who led a thorough systematic analysis of 22 relevant studies on the topic along with colleagues Patrick Markey at Villanova University and Rune Nielsen at IT University Copenhagen. The results of this meta-analysis are published in Springer's journal Psychiatric Quarterly.

New research may help to develop effective pain killers

The nerve cells that transmit pain signals in the body are called nociceptors. When activated they release pro-inflammatory neuropeptides. In order to recognise harmful external influences, nociceptors are equipped with a wide range of receptors. The capsaicin receptor channel, for example, reacts strongly to the spicy substance in chili peppers. Another receptor is sometimes called the mustard oil receptor as it is activated by a substance found in mustard, horseradish and onions. This receptor, whose scientific name is TRPA1, plays a key role in painful inflammation of the bowel and the pancreas, as well as in asthma.

Study pinpoints behavior type linked to binge drinking in young adults

While there are a number of studies on alcohol misuse, most of the research has been focused on the adult population. Alcohol is the most widely used drug among young adults between the ages of 18 to 25. Binge drinking—almost a rite of passage—peaks during the college years. So this begs the question, "Are there specific characteristics associated with high-level binge drinking habits in college students?"

Towards a cure for herpesviruses: Targeting infection with CRISPR/Cas9

Most adults carry multiple herpesviruses. Following the initial acute infection, these viruses establish life-long infections in their hosts and cause cold sores, keratitis, genital herpes, shingles, infectious mononucleosis, and other diseases. Some herpesviruses can cause cancer in man. During the latent phase of infection, the viruses remain dormant for long periods of time, but retain the capacity to cause occasional reactivations, that may lead to disease. A study published on June 30th in PLOS Pathogens suggests that attacking herpesvirus DNA with CRISPR/Cas9 genome editing technology can suppress virus replication and, in some cases, lead to elimination of the virus.

Ending Tuberculosis in Afghanistan

Afghanistan is one of 22 countries with a high burden of tuberculosis (TB) according to the World Health Organisation (WHO). The estimated number of new cases each year is a staggering 53,000 and as many as 12,000 afflicted by this curable infection lose their lives each year. For a large number of those infected, a timely diagnosis and effective treatment is out of reach due to high levels of poverty, lack of access to effective healthcare, and ongoing conflict in large parts of the country. It is not a surprise that a significant number of victims are women and children due to their vulnerable status in a society ravaged by decades of war, drought and migration. Some of these challenges such as poverty and lack of access to healthcare facilities are not unique to Afghanistan, but it is the only country, out of 22 that account for 80% of TB cases in the world, that has been utterly decimated by over four decades of war and migration.

Pea plants demonstrate ability to 'gamble'—a first in plants

An international team of scientists from Oxford University, UK, and Tel-Hai College, Israel, has shown that pea plants can demonstrate sensitivity to risk - namely, that they can make adaptive choices that take into account environmental variance, an ability previously unknown outside the animal kingdom.

Deceptive sexual signals keep the peace in a bonobo society

Female bonobos could have become the dominant sex in their societies by deceiving males as to when they are likely to conceive, according to research published in the open access journal BMC Evolutionary Biology. The females' unreliable sexual swellings, which can remain swollen up to 31 days, make it difficult for a male to monopolize and guard female mates to ensure he sires their offspring. This may reduce aggressive mate competition and male sexual coercion toward females, and result in bonobo societies being relatively peaceful.

Fruit flies adjust to sudden drops in temperature; just keep buzzing about the fruit bowl

Fruit flies may seem simple, but these common visitors to the fruit bowl can drastically alter their gene expression and metabolism to respond to temperature changes in their environment, an international team of researchers have shown.

Honeybees threatened by virulent virus

Researchers have found that honeybees in Europe are at significantly higher risk from an emerging viral variant, according to a new study published in the Proceedings of the Royal Society B.

Researchers identify calorie-burning pathway in fat cells

Investigators at Dana-Farber Cancer Institute in collaboration with scientists at the University of California, Berkeley, have identified a natural molecular pathway that enables cells to burn off calories as heat rather than store them as fat. This raises the possibility of a new approach to treating and preventing obesity, diabetes, and other obesity-linked metabolic disorders including cancer.

Similarities found in bee and mammal social organization

New research shows similarities in the social organisation of bees and mammals, and provides insight into the genetics of social behavior for other animals. These findings, published in PLOS Computational Biology, use sociogenomics - a field that explores the relationship between social behaviour and the genome - to show strong similarities in socially genetic circuits common in honey bees and mammals.

Scientists discover maleness gene in malaria mosquitoes

Scientists, led by Dr Jaroslaw Krzywinski, Head of the Vector Molecular Biology group at The Pirbright Institute have isolated a gene, which determines maleness in the species of mosquito that is responsible for transmitting malaria. The research, published in the journal Science, describes identification and characterisation of a gene, named Yob by the authors, which is the master regulator of the sex determination process in the African malaria mosquito, Anopheles gambiae, and determines the male sex.

The Earth's biodiversity could be much greater than we thought

After centuries of study, you'd think we'd have at least a rough idea of how many different species of life exist on Earth. This is becoming even more pressing as biodiversity disappears at an increasing pace due to human impacts. Some species are going extinct even before we discover them.

How a germ catches a virus

Bacteriophages – short phages – represent a group of small viruses that infect bacteria and are able to alter or destroy them. That is why their name can be translated as bacteria-eater. In order to infect a bacterium, a phage has to first recognize structures on the bacterial cell wall and adhere to it. Under the leadership of Professor Thilo Stehle, Cengiz Koç and other coworkers of the Collaborative Research Center 766 (The Bacterial Cell Envelope) at the University of Tübingen have investigated this mechanism of recognition. They focused their studies on the pathogenic bacterium Staphylococcus aureus and the phage Phi11, which infects staphylococci. The scientists identified a phage protein that mediates the recognition of the receptor on the bacterium. Details on the three-dimensional structure of this protein and its mode of recognition of the bacterial receptor were elucidated with the help of X-ray structure analysis.

What do sperm whales say?

When a team of researchers began listening in on seven sperm whales in the waters off the Azores, they discovered that the whales' characteristic tapping sounds serve as a form of individual communication. But what are they actually saying?

Resistance to antibiotics and to immune system are interconnected in bacteria

Antibiotics and the immune system are the two forces that cope with bacterial infections. Now, two studies from Isabel Gordo's laboratory, at Instituto Gulbenkian de Ciência (IGC, Portugal), show for the first time that resistance to antibiotics and to the immune system is interconnected in bacteria. The researchers further discovered that bacteria adaptation to the immune system influences the spectrum of antibiotic resistance and, as a side effect, bacteria become more resistant to some antibiotics, but also more sensitive to other classes of antibiotics. These results were now published in the scientific journals Antimicrobial Agents and Chemotherapy and Evolutionary Applications.

Researchers develop effective strategy for disrupting bacterial biofilms

Biofilms are communities of bacteria that adhere to a surface and are nearly impossible to eradicate when they are pathogenic, or disease-causing. Fortunately, a discovery from the laboratories of Lauren Bakaletz, PhD, and Steven Goodman, PhD, in The Research Institute at Nationwide Children's Hospital, provides strong evidence that an innovative therapeutic approach may be effective in the resolution of bacterial biofilm diseases.

In times of great famine, microalgae digest themselves

In a recent study, scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have determined the molecular mechanisms which microalgae apply in order to switch from rapid cell division to growth-arrest during times of acute nutrient deficiency. In laboratory experiments, the scientists have been able to observe that calcifying microalgae in a state of nutrient deficiency initially tweak their metabolism to be more economic and efficient before, out of necessity, they even partially digest themselves. The molecular switches for these basic functions of cells are strikingly similar in all living things. Apparently, it is these switches, which, when malfunctioning in humans, cause cells to lose control of their division activity and potentially become cancer cells. The new findings are being published online this week in the journal Frontiers of Marine Science.

Nobel winners slam Greenpeace on GMO crops

About a third of living Nobel laureates—108 at last count—have signed an open letter Thursday which attacks Greenpeace for campaigning against genetically modified crops, especially one called Golden Rice.

Researchers discover first sleeper goby cavefish in Western Hemisphere

Researchers have described a new genus and species of cavefish from Mexico - the Oaxaca Cave Sleeper. It has not been collected or seen in more than 20 years and lives in a cave system threatened by damming. Less than 0.5 percent of all fish species are cave-adapted and most of them are endangered because their cave habitats are limited and vulnerable to environmental threats.

Tracking animal migrations has become easier... now what?

Salmon navigate across vast swaths of open ocean and a maze of branching river networks to locate their natal waters. For years, scientists have described this as heroic feats of individuals.
