Philadelphia, June 30, 2020 - Auditory hallucinations, a phenomenon in which people hear voices or other sounds in the absence of external stimuli, are a feature of schizophrenia and some other neuropsychiatric disorders. How they arise in the brain has been unclear, but new research indicates that altered brain connectivity between sensory and cognitive processing areas may be responsible.
A multidisciplinary team from two Johns Hopkins University institutions, including neurotoxicologists and virologists from the Bloomberg School of Public Health and infectious disease specialists from the school of medicine, has found that organoids (tiny tissue cultures made from human cells that simulate whole organs) known as "mini-brains" can be infected by the SARS-CoV-2 virus that causes COVID-19.
ATHENS, Ohio (June 30, 2020) - The South Pole has been warming at more than three times the global average over the past 30 years, according to research led by Ohio University professor Ryan Fogt and OHIO alumnus Kyle Clem.
Chanterelles (Cantharellus cibarius) are one of the most popular mushrooms in Germany. Depending on the weather, chanterelle season starts in early July. Connoisseurs value the mushroom's delicate fruity aroma, which is reminiscent of apricots, and its aromatic and slightly bitter taste profile. Not only do chanterelles have a unique flavor profile, they also function as taste enhancers, lending dishes a well-rounded mouthfeel and a lingering, rich flavor.

The database comprises information on the so-called "ground reaction force" (GRF) which is the force between the foot and the ground that is generated during movement. It is an important standard parameter used in clinical practice and in research. The figures form the basis for diagnosis and for the assessment of therapeutic success.
EAST HANOVER, NJ - June 30, 2020 - On a June 24 webinar, titled, "The ADA Generation: A Dialogue with Recent College Graduates with Disabilities," experts in employment and disability engaged with three young professionals to relate the results of a new national survey to the real-world experiences of recent college graduates with disabilities.
For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals. Critical for brain development and function, the receptor converts chemical messages between cells into electrical signals within a neuron. The key to transmitting that information is opening the receptor's built-in ion channel, a hollow pore that allows electrically charged ions to flow.
Measurements from NASA's Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of the bizarre environment of KELT-9 b, one of the hottest planets known.
Changes in blood platelets triggered by COVID-19 could contribute to the onset of heart attacks, strokes, and other serious complications in some patients who have the disease, according to University of Utah Health scientists. The researchers found that inflammatory proteins produced during infection significantly alter the function of platelets, making them "hyperactive" and more prone to form dangerous and potentially deadly blood clots.
"Clean margins" are a goal of cancer excision surgery. If even a small piece of cancerous tissue is left behind, it increases the likelihood of a local recurrence and spread of the disease, possibly reducing overall survival time.
As the world wrestles with the coronavirus (COVID-19) pandemic, which arose after the virus jumped from an animal species to the human species, University of Delaware researchers are learning about new ways other pathogens are jumping from plants to people.
Opportunistic bacteria -- salmonella, listeria and E. coli, for example -- often piggyback on raw vegetables, poultry, beef and other foods to gain entry into a human host, causing millions of foodborne illnesses each year.
All life depends on a genome, which acts as an instruction manual for building all the products essential for development and survival. But knowing which of these individual instructions - or genes - need to be read, and when, is key for a properly functioning organism: so how does life get this right?
Experiments in mice have shown early success in vaccinating them against potentially deadly bacterial infections, such as methicillin-resistant Staphylococcal aureus, or MRSA, the strain resistant to most drug treatments.
The new vaccination strategy, developed by researchers at NYU Grossman School of Medicine, targets toxic molecules released by all Staphylococcal bacteria, called leukocidins, rather than directly targeting the bacteria.
Using the European Southern Observatory's Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright and partially obscured by dust. An alternative explanation is that the star collapsed into a black hole without producing a supernova. "If true," says team leader and PhD student Andrew Allan of Trinity College Dublin, Ireland, "this would be the first direct detection of such a monster star ending its life in this manner."
New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body. Their study was recently published in the International Journal of Molecular Sciences.
