Social isolation and loneliness increase the risk of death from heart attack, stroke

A new scientific statement from the American Heart Association finds that social isolation and loneliness are associated with a 30% increased risk of heart attack or stroke. Younger adults, including Gen Z, experience increased social isolation and loneliness due to higher social media use and less in-person engagement.

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.

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.
