Innovative bracing for durable structures

Across the world, severe earthquakes regularly shake entire regions. More than two billion people live in danger zones – many of them in structures not built to withstand an earthquake. Together with partners from industry, researchers at the Fraunhofer Institute for Wood Research WKI are developing building materials designed to prevent buildings from collapsing in a natural disaster.

Defect-free coatings for silicon spheres

The prototype kilogram – to which all scales are calibrated to – is losing weight. International efforts are striving to redefine the base unit for measuring mass and, in future, redefine the kilogram on natural constants. For this purpose, the Avogadro experiment determines the number of atoms in almost perfect silicon spheres. Fraunhofer researchers have recently succeeded in homogeneously coating the spherical surfaces – the measurement uncertainty can be limited to a range below 10 micrograms.

Virtual laboratory—fast, flexible and exact

During the forming process, sheet metal materials are often stressed to their limits. Computer simulations are used to test how far it is possible to go in production. However, the simulation is only ever as exact as the data on which it is based. Fraunhofer scientists have now developed a virtual test laboratory that allows them to examine different load states for metal materials and determine precise mechanical data.

Mobile control with facial gestures

Mobile devices play an increasingly important role in our lives; in some situations, though, they cannot be adequately managed and even accepting a call is a real challenge. In a study, researchers at the Fraunhofer Institute for Computer Graphics Research IGD in Rostock, Germany have evaluated which alternative control concepts are suitable to supplement the conventional use of mobile devices. EarFieldSensing (EarFS), the proprietary development that recognizes facial gestures via a special ear plug, has a lot of potential and offers further development possibilities besides its use on mobile devices.

Medicine & Health news

Popular heartburn drugs linked to higher death risk

Popular heartburn drugs called proton pump inhibitors (PPIs) have been linked to a variety of health problems, including serious kidney damage, bone fractures and dementia. Now, a new study from Washington University School of Medicine in St. Louis shows that longtime use of the drugs also is associated with an increased risk of death.

Menstruation doesn't change how your brain works—period

A new study published in Frontiers in Behavioral Neuroscience today is setting out to change the way we think about the menstrual cycle. While it's often been assumed that anyone who's menstruating isn't working at top mental pitch, Professor Brigitte Leeners and her team of researchers have found evidence to suggest that that's not the case. They examined three aspects of cognition across two menstrual cycles, and found that the levels of oestrogen, progesterone and testosterone in your system have no impact on your working memory, cognitive bias or ability to pay attention to two things at once. While some hormones were associated with changes across one cycle in some of the women taking part, these effects didn't repeat in the following cycle. Overall, none of the hormones the team studied had any replicable, consistent effect on study participants' cognition.

Personalized metabolic therapy treatment shows improvement on atypical Rett syndrome

A translational, multicenter study has unveiled the potential of D-serine—a dietary supplement—to improve the neuronal function of a patient with a mutation of the glutamate receptors associated to atypical Rett syndrome with severe encephalopathy. This collaborative study, led by Dr. Xavier Altafaj (Neuropharmacology Unit, IDIBELL) and published in Biological Psychiatry, opens a new range of therapeutic options for patients with mutations that affect glutamatergic neurotransmission. Likewise, this study has allowed scientists to establish a unique and novel experimental approach to design personalized treatments for other mutations that affect glutamatergic transmission.

Study finds automated embryo assessment system more accurate than that of embryologists

Embryo quality has long been considered the main determinant of implantation and pregnancy in IVF. Morphology - a visual assessment of an embryo's shape and development - has since the very first days of IVF been the key to measuring this embryo quality, and only in recent years has this morphological grading been made somewhat more scientific with the introduction of time-lapse imaging. Yet the fact remains that many morphologically "good quality" embryos in IVF - between 30 and 60% in various studies - fail to implant in the uterus and make a pregnancy. What's going wrong?

The transfer of chromosomally 'abnormal' embryos can still result in pregnancy in IVF

IVF embryos whose cells have mixed chromosomal profiles - one normal, another abnormal - still have the potential to implant in the uterus and become a healthy pregnancy, according to a study presented today at the 33rd Annual Meeting of ESHRE.

New pestivirus that attacks the nervous system of Austrian pigs

Some newly born piglets shiver even when they are kept warm. So-called "shaking piglets" have symptoms that resemble those of the classical swine fever, with extensive damage to the brain and the spinal cord. The viral origin of the disease was clarified only recently with the discovery in Europe and the USA of an atypical porcine pestivirus. Researchers at the Vetmeduni Vienna have now discovered a further new virus in shaking piglets on an Austrian farm. The pathogenic agent is related to the Australian Bungowannah virus and more distantly to the classical swine fewer virus. Because of the symptoms it causes, the new virus is termed LINDA virus (Lateral shaking Inducing NeuroDegenerative Agent). Its discovery was recently announced in the journal Emerging infectious diseases.

Better bacteria-busting techniques could make oil extraction greener and cheaper

Simple tweaks to oilfield practice could provide the offshore industry with a more sustainable solution to environmental and commercial threats posed by harmful bacteria in subsea oil deposits.

Size of animals dating back 100-350 million years ago inferred from resurrected proteins

Titin is one of the proteins that make up the muscles of all vertebrates; it is an elastic protein that acts as a spring by refolding and returning to its original state. "Protein evolution has been studied from many points of view: its thermal stability, function and structure, but no one had ever studied the evolution of the mechanical properties of a protein. For titin this is a particularly appropriate approach given its function," said Pérez-Jiménez.

Andean orchids – not so ancient

The Andes are the world's most species rich biological diversity hotspot, containing an astounding 15% of the world's plant species, despite making up only 1% of the earth's surface. Orchids are a key element of Andean plant life, but despite their importance and abundance, particularly epiphytic orchids (plants that grow on other plants) their origin has not yet been studied in great detail. "Orchids are not only popular in horticulture but also great models to understand evolution" says Professor Alexandre Antonelli at the Gothenburg Global Biodiversity Centre, senior author of the study.

Fungi are key players of the deep biosphere

In addition to the life on the surface of the Earth and in its oceans, ecosystems have evolved deep under us in a realm coined the "deep biosphere" which stretches several kilometers down into the bedrock. Down there, the conditions are harsh and life is forced to adjust to a lifestyle that we at the surface would call extreme. One major difference to surface conditions is the lack of oxygen; a compound we take for granted and consider to be a prerequisite for survival but which subsurface life has to cope without.

Helium ions reveal how viruses attack bacteria

An interdisciplinary research consortium from the Nanoscience Center at University of Jyvaskyla in Finland (group leaders Dr. Lotta-Riina Sundberg and Prof. Ilari Maasilta) has found that bacteria and viruses can be imaged with helium ions in contrast to electrons, which are the standard workhorse in nanoscale microscopy. Helium ions, being more massive than electrons, can be focused to a much tighter spot down to the atomic length scales. By measuring the electrons generated by the ion bombardment, an image can be formed from the sample with biological features visible below the nanometer (one billionth of a meter) length.

Imperial academic discusses his work on algae fuel factories
