COVID-19 infections can result in long-lasting neurological symptoms. New research suggests an already approved anti-viral may inhibit viral replication and rescue impaired neurons.

Researchers have discovered the mechanistic steps underlying a new type of synaptic plasticity called behavioral timescale synaptic plasticity (BTSP). The study reveals how the entorhinal cortex (EC) sends instructive signals to the hippocampus -- the brain region critical for spatial navigation, memory encoding, and consolidation -- and directs it to specifically re-organize the location and...
Scientists illuminated the molecular events underlying an inherited movement and neurodegenerative disorder known as ARSACS -- Autosomal recessive spastic ataxia of Charlevoix-Saguenay, named for two Quebec valleys where the first cases were found.
Maternal consumption of a Western-style diet alters the transcriptional landscape of fetal blood stem cells in rhesus macaques, researchers report.
A new collaborative study shows how blood vessel genes play a critical role in motor neuron development by telling blood vessels to get out of the way. The discovery has implications for understanding diseases in which motor neuron connections are destroyed, such as amyotrophic lateral sclerosis (ALS) or spinal muscular atrophy (SMA).
A new global COVID-19 study provides actionable recommendations to end the public health threat without exacerbating socio-economic burdens or putting the most vulnerable at greater risk.
Researchers find data collected by mobile phones could be used to evaluate the structural integrity of bridges.
A new genetic study finds large dams restrict platypus movement, with significant implications for their conservation.
In a study of nearly 100 women, participants with certain dissociative symptoms had increased connections within some brain networks and decreased connections within others. The new findings shed light on the brain connectivity associated with these debilitating symptoms and ultimately may help clinicians diagnose and treat affected patients.
Plants need light to grow. However, due to excess nutrients and/or the absence of herbivores less light can reach lower vegetation layers in grasslands. Consequently, few fast-growing species dominate and plant diversity declines. So far, this relationship has been established indirectly through experiments, but never directly by means of experimentally adding light in the field. Now biologists...
Researchers have provided the first demonstration of a progressive increase in epileptic spasms along with learning and memory deficits in an animal model of this disorder.
It's not the individual brain regions but rather their connections that matter: neuroscientists propose a new model of how the brain works. This new view enables us to understand better why and how our brains vary between individuals.
Some genetic variants may put people at risk of autoimmune diseases while conferring protection against the outcome of viral infection. A new study suggests that genetic predisposition for systemic lupus erythematosus (SLE) may be protective against severe COVID-19 infection.
Using images captured by satellites, researchers have confirmed that the January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano produced the highest-ever recorded plume. The colossal eruption is also the first to have been directly observed to have broken through to the mesosphere layer of the atmosphere.
A new treatment for neurological and psychiatric diseases, that works by reducing the excitability of overactive brain cells, has been developed.
The first observations of a mass-accreting black hole from the Imaging X-Ray Polarimetry Explorer (IXPE) mission reveal new details about the configuration of extremely hot matter in the region immediately surrounding it. Researchers are using measurements of the polarization of X-rays to test and refine models that describe how black holes swallow matter, becoming some of the most luminous...
Scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date.
A new study finds the microbial ecosystem in the guts of wild marten (Martes americana) that live in relatively pristine natural habitat is distinct from the gut microbiome of wild marten that live in areas that are more heavily impacted by human activity. The finding highlights an emerging tool that will allow researchers and wildlife managers to assess the health of wild ecosystems.
Finding uncovers a key property needed for CELMoD drugs, a type of protein degrader, to work effectively.
A new study compares the self-esteem and social activities of teens with no or poor home Internet access to teens who are the heaviest users of screens as well as teens with parents who tightly control or limit their screen use.
In the U.S. Geological Survey's Non-Indigenous Aquatic Species database, these so-called 'native transplant' fish are almost twice as common as fish introduced from outside the country. But a new review says native transplant fish, especially those that don't qualify as game fish, are rarely studied and their impacts poorly understood.
A new method to treat sewage can efficiently convert leftover sludge to biogas, an advance that could help communities lower their waste treatment costs while helping the environment.
For years, scientists have seen enhanced photosynthesis as one of the only possible bright sides of increasing levels of atmospheric carbon dioxide (CO2) -- since plants use carbon dioxide for photosynthesis, it is anticipated that higher levels of the gas will lead to more productive plants. Scientists now explain why this effect may be less than expected because elevated levels of CO2 make it...
Patients with cancer and a weakened immune system who are treated with immunotherapies tend to fare far worse from COVID-19 than those who haven't received such therapies in the three months before their COVID diagnosis, show findings in a new study. Researchers found worse outcomes in both the disease itself as well as the fierce immune response that sometimes accompanies it.
Researchers have developed a fast and cost-effective method to test liquids for a ubiquitous family of chemical compounds known as amphiphiles, which are used to detect diseases such as early-stage tuberculosis and cancer as well as to detect toxins in drugs, food, medical devices and water supplies.
