Astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) and the Vatican Observatory (VO) teamed up to spectroscopically survey more than 1000 bright stars that potentially host exoplanets. The team presents precise values of 54 spectroscopic parameters per star in the first of a series of papers in the journal Astronomy & Astrophysics and releases all its data to the scientific community. This unprecedented large number of parameters will be essential to interpret the stellar light and find connections between…
Dementia with Lewy bodies (DLB), one of the most common forms of dementia, has no cure. Previous studies suggested that gut bacteria, the microorganisms that live in the human digestive tract, play a role in Parkinson’s disease, another neurodegenerative disorder, but the bacteria involved in DLB had not been identified. Now, a group led by researchers at the Nagoya University Graduate School of Medicine in Japan has identified three bacteria involved in DLB: Collinsella, Ruminococcus, and Bifidobacterium. Their findings, reported…
Infections with the fungus Aspergillus fumigatus are difficult to fight – especially because the fungus forms a biofilm and can thus protect itself from antifungal drugs and the immune defence system. The cancer drug Imatinib prevents the compartmentalisation. There are up to 10,000 fungal spores in every cubic metre of air that can enter our bodies when we breathe them in. Some of these belong to the species Aspergillus fumigatus, a widespread fungus found everywhere in the environment. In immunocompromised…
The seismic reflection method involves sending acoustic waves thousands of meters under the Earth’s surface. The reflected signals provide scientists with information about the characteristics of the subsurface. This is how oil and gas deposits can be discovered. While these will eventually no longer be extracted as we move away from fossil fuels, accurate knowledge of rock structures is important for better understanding known reservoirs. The Earth’s subsurface could be a key place to store greenhouse gases. With improved machine…
Extracted human teeth have long been used in conducting dental research, such as evaluating dental ceramic materials as a crown restoration on tooth. It is an inexpensive and straightforward process that simulates clinical situations. However, the collection and use of extracted human teeth is becoming increasingly difficult given the concerns about COVID-19, size-standardisation issues, and also time constraints. All these factors have prompted a need for dentine analogue materials that could potentially substitute extracted human teeth in laboratory-based mechanical and…
Glaciers – giant blocks of moving ice – along Antarctica’s coastline are flowing faster in the summer because of a combination of melting snow and warmer ocean waters, say researchers. On average, the glaciers travel at around one kilometre a year. But a new study has found a seasonal variation to the speed of the ice flow, which speeded up by up to 22 % in summer when temperatures are warmer. This gives an insight into the way climate change…
RNA nanosatellite leads researchers at Aarhus University and Berkeley Laboratory to the discovery of rules and mechanisms for RNA folding that will make it possible to build more ideal and functional RNA particles for use in RNA-based medicine. The RNA molecule is commonly recognized as messenger between DNA and protein, but it can also be folded into intricate molecular machines. An example of a naturally occurring RNA machine is the ribosome, that functions as a protein factory in all cells….
A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers. The researchers were led by a team that is part of the Penn State Center for Nanoscale Science (CNS), one of 19 Materials Research Science and Engineering Centers (MRSEC) in the United States funded by the National Science Foundation. Their work was published Feb. 13 in Nature Materials. A regular computer consists of billions…
The device could help workers locate objects for fulfilling e-commerce orders or identify parts for assembling products. MIT researchers have built an augmented reality headset that gives the wearer X-ray vision. The headset combines computer vision and wireless perception to automatically locate a specific item that is hidden from view, perhaps inside a box or under a pile, and then guide the user to retrieve it. The system utilizes radio frequency (RF) signals, which can pass through common materials like…
New method simultaneously monitors clumps and the mixing intensity in a single step. Water is a vital resource, and clean water is a necessity. Texas A&M University researchers have developed a new technique to monitor one of the key processes of purifying water in real time. Raw water contains microscopic pathogens that are too small to remove during water and wastewater treatment easily. Chemicals are added to form large clumps called flocs, which are easily filtered out. Flocculation is the…
New EU project to use supercomputers for improved Earth system simulations. The ocean has a large effect on our planet’s climate. In this regard, mesoscale – i.e., medium-sized – eddies, which constitute essentially the weather on the ocean, could be far more important than previously believed. Accordingly, a new project, led by the Alfred Wegener Institute has just been launched in order to more precisely assess this aspect: by doing so, “European Eddy Rich Earth System Models” (EERIE) could significantly…
Entangled photon pairs to help fighting cancer. The recently launched QEED project aims to significantly reduce measurement time in clinical cancer diagnostics by developing a spectrally resolved imaging technique based on entangled photon pairs. FBH scientists will develop the required diode lasers and quantum light modules. The in-house Prototype Engineering Lab will then assemble these modules together with the project partners’ components into the ready-to-use QEED system. Funding is provided by the German Federal Ministry of Education and Research (BMBF)….
By monitoring the body’s molecular response to a viral attack, the new method developed by Flatiron Institute researchers and their colleagues can diagnose even asymptomatic patients with 98.4 percent accuracy. By inspecting the body’s immune response at a molecular level, a research team has developed a new way to test patients for COVID-19. Their method can potentially catch infections a matter of hours after exposure — far earlier than current COVID-19 tests can detect the virus — with near-perfect accuracy….
New cell therapy offers potential treatment option for patients with chronic heart failure. Physician-scientists at The Texas Heart Institute announced today the results of the largest cell therapy trial to date in patients with chronic heart failure due to low ejection fraction. The therapy benefited patients by improving the heart’s pumping ability, as measured by ejection fraction, and reducing the risk of heart attack or stroke, especially in patients who have high levels of inflammation. Also, a strong signal was…
Higher order statistical analysis of protons emitted from wide range of gold-gold collision energies shows clear absence of a quark-gluon plasma (QGP) at the lowest energy. Physicists report new evidence that production of an exotic state of matter in collisions of gold nuclei at the Relativistic Heavy Ion Collider (RHIC)—an atom-smasher at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory—can be “turned off” by lowering the collision energy. The “off” signal shows up as a sign change—from negative to positive—in data…
