Low addiction risk with medical use of ketamine

A recent study from the University of Geneva suggests that ketamine's therapeutic use may be safe due to its limited impact on dopamine levels and neuronal communication. The research found that ketamine triggers a short increase in dopamine, but also inhibits a specific receptor that prevents addiction progression.

Only 1 in 5 Syrian children in refugee camps show resilience to mental health problems

New research reveals that only 1 in 5 Syrian children living in refugee camps exhibit resilience to mental health problems. The study found that factors such as the child's environment, caregiver interactions, and access to resources significantly impact their ability to recover from war trauma.

Inflammation accelerates aging of the hematopoietic system

A recent study published by the German Cancer Research Center found that inflammation in early life leads to a permanent decline in functional blood stem cells, suppressing their ability to regenerate. Mice exposed to inflammatory challenges developed clinically relevant features of aging, including anemia and decreased number of cells...

How the genome is packed into chromosomes that can be faithfully moved during cell division

The Gerlich Group at IMBA found that histone acetylation establishes a sharp surface boundary on chromosomes, resisting microtubule perforation. Chromatin phase separation and DNA looping by condensin cooperates to build mitotic chromosomes with unique physical properties.

NCAR study identifies where coral reefs may be buffered against warming oceans

Scientists have identified possible 'thermal refugia' where coral reefs are more likely to survive warming oceans. An interactive global atlas has been created with locations of these areas, providing a starting point for conservation efforts.

Multidisciplinary team of Boston University and EcoHealth Alliance researchers will work to prevent future pandemics

A team of researchers from Boston University and EcoHealth Alliance will develop models to predict disease emergence and spread. They aim to identify location hotspots for pathogen emergence and determine the most effective pandemic mitigation strategies using data from COVID-19, H1N1 flu, and Ebola Virus Disease.

Explosive neutron star merger captured for first time in millimeter light

A team led by Northwestern University captured millimeter-wavelength light from a neutron star merger for the first time, revealing one of the most energetic short-duration gamma-ray bursts. The discovery opens up new study areas, as scientists can now observe more of these events with ALMA and other telescope arrays.

Seeing through someone else's eyes: Proposing objective criteria to examine subjective experiences

Ben-Gurion University researchers Dr. Moti Salti and Dr. Dafna Bergerbest propose a framework to objectively compare subjective experiences and reveal their neuronal basis. They focus on numerosity as a field where objective criteria can be established, aiming to map individual transfer-functions at both behavioral and neuronal levels.

Low pressure, high stakes: UNLV physicists make major gains in race for room-temperature superconductivity

A team of UNLV physicists has replicated room-temperature superconductivity at the lowest pressure ever recorded, building on their 2020 landmark discovery. By tuning the composition of carbon, sulfur, and hydrogen, scientists have produced a material that retains its state of superconductivity at lower pressures.

Out with a bang: Explosive neutron star merger captured for the first time in millimeter light

Researchers recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star, confirming it as one of the most energetic short-duration gamma-ray bursts ever observed. The results reveal that the explosion left behind one of the most luminous afterglows on record.

Children and teens getting spinal surgery don’t need so many opioids, study suggests

A Michigan Medicine study found that patients who received preoperative education on opioid risks and nonopioid pain management options consumed significantly less oxycodone, with only 16 doses used despite similar pain scores. The results suggest a multimodal approach to managing pain can reduce harm and prevent substance use disorders.

Global spread of powdery mildew through migration and trade

A research team uncovered the secret of powdery mildew's success by comparing genetic compositions of 172 strains from 13 countries on five continents. The pathogen was introduced to new regions through human migration and trade, undergoing hybridization with local species to form better-adapted hybrids.
