Astrocyte Cells Critical For Learning Skilled Movements

When astrocyte function is disrupted, neurons in the brain’s motor cortex struggle to execute and refine motion, a new study in mice shows.

Study: Shutting Down Nuclear Power Could Increase Air Pollution

If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

How A Small, Unassuming Fish Helps Reveal Gene Adaptations

At first blush, sticklebacks might seem a bit pedestrian. The finger-length, unassuming fish with a few small dorsal spines are a ubiquitous presence in oceans and coastal watersheds around the northern hemisphere.

Decoding How Bacteria Talk With Each Other

Bacteria, the smallest living organisms in the world, form communities where unified bodies of individuals live together, contribute a share of the property and share common interests.

Students Of Innovative Course Report Significantly Improved Mental Health And Flourishing

Navigating the transitional stress of starting college can challenge young adults’ mental health. Thrust into unfamiliar social situations and new home environments, students face increased academic pressure and the responsibility of making important life decisions for the first time.

A Cheap, and High-Capacity Battery That Does Not Catch on Fire or Explode

Researchers from the Czech Academy of Sciences have patented an invention that might fix the problem with batteries catching on fire. The experimental high-voltage aqueous battery, built as a joint effort of the Institute of Physics and the J. Heyrovsky Institute of Physical Chemistry of the Czech Academy of Sciences (CAS), is based on dual-ion electrochemical reactions. The new battery provides a life-cycle of 500 discharge/charge cycles, and its capacity is comparable to that of the commercially available nickel-metal hydride batteries. But unlike them, the aqueous battery is made of extremely cheap materials.

Most Preprint Studies Of COVID-19 Hold Up Through Peer-Review

Research findings posted online as preprints — studies made public before undergoing the review and approval of a panel of peer scientists required by most scholarly journals — often hold up quite well to that scrutiny, according to a new report on COVID-19 studies.

Improved Understanding Of Early Spinal Cord Development Paves The Way For New Treatments

Researchers at the University of Wisconsin–Madison are developing the means to turn stem cells into a wide range of specific types of spinal cord neurons and cells in the hindbrain — the critical nexus between the spinal cord and the brain — paving the way for improved prevention and treatment of spinal cord disease.

Despite Commitments, Brazil’s Beef Sector Tainted By Purchases From Protected Lands In Amazon Basin

Depending on where it’s from, your next steak could come with a side of illegal deforestation.

Wild Primate Virus Has Pandemic Potential Should It Jump The Species Barrier, Shows Study

In a world still reeling from COVID-19, infectious disease researchers are eager to head off the next pandemic before it has the chance to spill over from animals to humans

Detection of Defects in Graphene Thanks to a Unique Combination of Two Methods

Graphene has very unique properties and could improve many components and devices. A detailed understanding of the physicochemical properties of this 2D material - including the role of structural defects - is essential for its successful use in practice. Scientists at the J. Heyrovský Institute of Physical Chemistry of the Czech Academy of Sciences have found that by combining two different measurement methods, they can determine the role graphene defects play in transitions between electronic states and electrochemical reactions.

Wearable Sensor Can Help Unlock The Potential Of Exosuits In Real-World Environments

Wearing an exosuit could help people rehab from an injury or even give them extra oomph if they’re carrying something heavy.

Scientists Map Gusty Winds In A Far-Off Neutron Star System

The 2D map of this “disk wind” may reveal clues to galaxy formation.

The Role of Disordered Protein Interactions in Gene Expression Highlighted

A team led by researchers at Baylor College of Medicine and the Czech Academy of Sciences has uncovered a new piece of the puzzle of how gene expression is orchestrated. Published in the journal Science, the findings reveal a novel mechanism that coordinates the assembly of components inside cells that control gene expression. The mechanism not only is essential for normal cell function, but also has been implicated in cancer, neurodegeneration and HIV infection, and could suggest new ways to treat these conditions.

Partisan Divide Contributed To False Sense Of Racial Equality In Pandemic Mortality

The early months of the COVID-19 pandemic were marked by far higher death rates among Black people than white people in the United States. Before 2020 ended, however, differences between the two groups had nearly equalized.

Study: Smoke Particles From Wildfires Can Erode The Ozone Layer

MIT chemists show the Australian wildfires widened the ozone hole by 10 percent in 2020.

New Insights Into Training Dynamics Of Deep Classifiers

MIT researchers uncover the structural properties and dynamics of deep classifiers, offering novel explanations for optimization, generalization, and approximation in deep networks.

New Method Accelerates Data Retrieval In Huge Databases

Researchers used machine learning to build faster and more efficient hash functions, which are a key component of databases.

New “Traffic Cop” Algorithm Helps A Drone Swarm Stay On Task
