Non-hallucinogenic psychedelic analog reverses effects of stress in mouse study

Eurekalert - May 25 2021 - 00:05
A novel compound similar in structure to the psychedelic drug ibogaine, but lacking its toxic and hallucinogenic effects, has been found to rapidly reverse the effects of stress in mice. Researchers found that a single dose of tabernanthalog (TBG) can correct stress-induced behavioral deficits, including anxiety and cognitive inflexibility, and also promotes the regrowth of neuronal connections and restores neural circuits in the brain that are disrupted by stress.

Cocaine's effect on the brain: Fruit fly research shows impact at the cellular level

Eurekalert - May 25 2021 - 00:05
New research from the Clemson University Center for Human Genetics has identified specific cell clusters in the brain of the common fruit fly affected by acute cocaine exposure, potentially laying the groundwork for the development of drugs to treat or prevent addiction in humans.

Serendipitous discovery could lead to treatment for strokes, cardiac arrest

Eurekalert - May 25 2021 - 00:05
Lack of oxygen, which is harmful to the brain, causes hydrogen sulfide "sewer gas" to accumulate in the brain. The brains of lab animals repeatedly exposed to hydrogen sulfide became tolerant to the gas and lack of oxygen. Researchers identified the mechanism that induces this tolerance, which could lead to new treatments for brain injuries caused by oxygen deprivation.

Microbes metabolizing toxic substances were found in the burning coal seams of Kuzbass

Eurekalert - May 25 2021 - 00:05
Underground coal seams engulfed in a fire are not a very pleasant place to live. Nevertheless, Russian scientists, while examining the quarries of the Kemerovo region, showed that microorganisms also live there. They are similar to those that inhabit hot springs and other harsh habitats and are capable of metabolizing carbon monoxide, hydrogen, nitrates, and other compounds that are often hazardous to humans.

Unforeseen links to chronic pancreatitis found in cancer-related signals

Eurekalert - May 25 2021 - 00:05
Researchers from Osaka University have demonstrated that two signaling pathways, the PI3K and the Hippo pathways earlier implicated in the development of pancreatic cancer, are responsible for the development and progression of chronic pancreatitis. Experiments in animal models, corroboration by laboratory evidence, and studies of human diseased tissue suggest that targeting pathologically upregulated Connective Tissue Growth Factor (CTGF) may be a useful therapeutic strategy against this disease.

Study examines how pandemic-related changes affect college students' motivation

Eurekalert - May 25 2021 - 00:05
Despite concerns that remote learning would drive at-risk college students away, some students' motivation and interest in their studies increased during the pandemic, according to a study of underrepresented students in a biology course by researchers at the University of Illinois Urbana-Champaign.

Made in the shade or fun in the sun

Eurekalert - May 25 2021 - 00:05
For the first time, biologists have fully characterized the light-sensitive proteins of the phytochrome family from the common model plant Arabidopsis thaliana on a biochemical level. The scientists also extended that characterization into the phytochromes of two important food crops: corn and potatoes. Instead of finding that all phytochrome isoforms are identical, they found surprising differences.

Candid cosmos: eROSITA cameras set benchmark for astronomical imaging

Eurekalert - May 25 2021 - 00:05
A team of scientists from Germany developed the cameras for an astronomical instrument built to perform all-sky surveys in the x-ray wavelength regime. In their recently published paper, they highlight the features of the cameras, a key part of a telescope called eROSITA, describing the hardware development and ground testing, and report the performance aboard the satellite, opening doors to a deeper understanding of our cosmos.

SARS-CoV-2: Estimating infectiousness

Eurekalert - May 25 2021 - 00:05
Largest-ever study of viral load levels in patients with SARS-CoV-2: Researchers from Charité - Universitätsmedizin Berlin have analyzed the PCR samples of more than 25,000 persons with COVID-19. The team determined the viral loads of each individual sample and used their results to estimate levels of infectiousness. The research, which has been published in Science*, provides a clear idea of the infectiousness of the disease in different age groups and at different levels of disease severity.

Scientists discover a protein that naturally enhances wheat resistance to head scab

Eurekalert - May 25 2021 - 00:05
Fusarium Head Blight is caused by a fungus that produces heat-stable trichothecene mycotoxins, which help the disease spread. To stop the spread, plant breeders are working to develop cultivars with improved resistance to FHB. A team of plant pathologists primarily based at Rutgers University recently generated wheat overexpressing two non-specific lipid transfer proteins and found that this enhanced protection against the fungus and led to a reduction of one of the major mycotoxins.

Probing deeper into origins of cosmic rays

Eurekalert - May 25 2021 - 00:05
Researchers know cosmic rays originate from the multitude of stars in the Milky Way and other galaxies. The difficulty is tracing the particles to specific sources, because the turbulence of interstellar gas, plasma, and dust causes them to scatter and rescatter in different directions. In AIP Advances, researchers developed a simulation model to better understand these and other cosmic ray transport characteristics, with the goal of developing algorithms to enhance existing detection techniques.

Much of the conversation around COVID-19 focuses on death and survival. But 45% of patients hospitalized for the virus at Michigan Medicine during the pandemic's first wave experienced significant functional decline. Nearly 20% were discharged to a location other than their home. Researchers say this information highlights the true impact of COVID-19.

Clear differences in how Nordic journalists experience their professional role

Eurekalert - May 25 2021 - 00:05
Swedish and Danish journalists describe their role as monitorial to a greater extent than journalists from other Nordic countries. Journalists from Norway and Iceland state they have the least experience of political influence and thus differ from Finnish journalists. This is shown by a new comparative study published by Nordicom at the University of Gothenburg.
