Gene editing may be a potential treatment for anxiety and alcohol use disorder in adults who were exposed to binge drinking in their adolescence, according to the results of an animal study. The researchers used a gene-editing tool called CRISPR-dCas9 in their experiments to manipulate the histone acetylation and methylation processes at the Arc gene in models of adult rats.

As climate change continues to alter weather patterns around the planet including the Midwest, researchers are modeling the impact on crops such as corn.

In a review of 71 studies that explored links between belief in paranormal phenomena and cognitive function, most of the findings align with the hypothesis that such beliefs are associated with cognitive differences or deficits.

Researchers use silicon nanoparticles to help visualize the coalescence of quantized vortices that occur in superfluid helium, which can help improve our understanding of quantum fluids and materials, including superconductors.

Neuroscientists found that higher levels of the alpha-synuclein protein in the brain can lead to changes in vocal production.

A new study summarizing the 2020 California wildfire year said just over 9,900 wildfires burned 4.3 million acres in 2020. That's twice the previous record but only average compared to burn rates before Euro-American settlement. Fire severity is the far greater concern.

The virus that causes COVID-19 can develop partial resistance to the antiviral drug remdesivir during infection of cultured cells in the laboratory by more than one mechanism.

A study provides the first published in-depth description of the anti-cancer activity of capsaicin sustained release formulations. Capsaicin is naturally found in chili peppers and is the agent that provides the hot and spicy taste when eating chili peppers.

A new device uses millimeter-wave imaging -- the same technology used in airport security scanners -- to scan a patient's skin to detect if they have skin cancer. Millimeter-wave rays harmlessly penetrate about 2mm into human skin, so the team's imaging technology provides a clear 3D map of scanned skin lesions.

Scientists have developed a qubit platform formed by freezing neon gas into a solid, spraying electrons from a light bulb's filament onto it, and trapping a single electron there. This system shows great promise as an ideal building block for quantum computers.

A new study has for the first time identified which risk factors are more likely to trigger a heart attack or acute myocardial infarction (AMI) for men and women 55 years and younger.

Astronomers discovered a 'black widow binary' -- a rapidly spinning neutron star circling and slowly consuming a smaller companion star. Named ZTF J1406+1222, the pair has the shortest orbital period yet identified, and is unique in that it appears to host a third star that orbits around the two inner stars every 10,000 years.

Researchers have developed a genetic-risk score for identifying individuals who would benefit the most from lifestyle counseling to prevent gestational and postpartum diabetes.

Researchers have gained new insights into the cellular and molecular mechanisms of absence seizures and potential therapy options.

When the COVID-19 pandemic emerged, ultraviolet radiation became one of the go-to methods for preventing the spread of the SARS-CoV-2 virus, along with facemasks, hand sanitizer and social distancing. The problem: There was little research showing what UV dosage kills the virus. In a new study, researchers lay the foundation for health standards about what offers true disinfection.

Genes are the carriers of our genetic information. They are read in our cells and used to produce ribonucleic acids (RNAs). During this process, termed transcription, the enzyme RNA polymerase II has a decisive influence on the exact time at which genes are read and on the intensity with which this happens. In their recent article, researchers have shown exactly how RNA polymerase II is activated in nerve cells, and how this stimulates gene expression, the targeted use of genetic information. Their...

Researchers share the identification of a new potential target for CAR T cells called OR2H1 that they have demonstrated inhibits growth in lung and ovarian tumors.

More than 60 million magnetic resonance imaging (MRI) scans are performed worldwide each year, but imaging for the millions of patients with cardiac implantable electronic devices (CIEDs) such as pacemakers is a logistical challenge, because of concerns with how the magnetic field affects the implants. Now, a newly published study reveals safe and effective reprogramming of these devices is possible, even from a remote location.

Using second-long electrical shocks, scientists discovered they could control the types of cells in a community of bacteria. Being able to direct the ratio of cells holds implications for settings spanning agriculture to health care, where antibiotic resistance is a significant threat.

Hearing loss due to aging, noise and certain cancer drugs has been irreversible, because scientists have not been able to reprogram existing cells to develop into the outer and inner ear sensory cells -- essential for hearing -- once they die. But scientists now have discovered a single master gene that programs ear hair cells into either outer or inner ones, overcoming a major hurdle that had prevented the development of these cells to restore hearing.

When patients started showing adverse side effects during a cancer immunotherapy trial, researchers went back through the data and worked with patient samples to see what went wrong.

Dormant herpesviruses induce their reactivation via a previously unknown cellular mechanism mediated by a viral microRNA.

Substituting 20 % of meat from cattle with microbial protein -- a meat alternative produced in fermentation tanks -- by 2050 could halve deforestation, a new analysis finds. The market-ready meat alternative is very similar in taste and texture, but is a biotech product which -- by replacing beef -- involves much less land resources and greenhouse gas emissions from agriculture and land-use change. This goes under the assumption of a growing world population's increasing appetite for beefy bites... Читать дальше...

New research found that in families where adults sacrifice their own nutritional needs so that their offspring are fed first, the mental health of both groups is less severely affected, although it is nevertheless affected.

Plants can't speak up when they are thirsty. And visual signs, such as shriveling or browning leaves, don't start until most of their water is gone. To detect water loss earlier, researchers have created a wearable sensor for plant leaves. The system wirelessly transmits data to a smartphone app, allowing for remote management of drought stress in gardens and crops.
