Effects on memory of neuron diversity in brain region revealed
Neurons in a key area of the brain have different functions based on their exact genetic identity, and understanding this diversity could lead to better understanding of the brain’s computational flexibility and memory capacity, potentially informing d…
Researchers analyze THC in breath of cannabis smokers
Researchers analyzed THC levels in the breath of people who use cannabis regularly, both before and after they smoked marijuana. The researchers found that THC levels spanned a similar range across pre- and post-use samples. ‘In many cases, we would no…
Brain signatures for chronic pain identified in a small group of individuals
Researchers have recorded pain-related data from inside the brain of individuals with chronic pain disorders caused by stroke or amputation (phantom limb pain). A long sought-after goal has been to understand how pain is represented by brain activity a…
Limiting global warming to 1.5°C would save billions from dangerously hot climate
Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests.
Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to ‘the Great Dying’
A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world’s…
Communities should reconsider walking away from curbside recycling, study shows
Researchers took a deep dive into the economic and environmental value of community recycling efforts and compared it to the value of other climate change mitigation practices, concluding it provides a return on investment.
A giant leap forward in wireless ultrasound monitoring for subjects in motion
Engineers have developed the first fully integrated wearable ultrasound system for deep-tissue monitoring, including for subjects on the go.
‘Lost’ immune cells partly to blame for reduced vaccine response in older people
Researchers have shown that within immune structures called the germinal centre, the mislocation of Tfh cells causes reduced capacity to respond well to vaccination with age. The research also identified that Tfh cells have a previously unappreciated r…
Stretching metals at the atomic level allows researchers to create important materials for quantum, electronic, and spintronic applications
A University of Minnesota Twin Cities-led team has developed a first-of-its-kind breakthrough method that makes it easier to create high-quality metal oxide films that are important for various next generation applications such as quantum computing and…
New supply chain model to empower seabound hydrogen economy
A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Nitrate: Healthy heart or cancer risk? Meet nutrition’s Jekyll and Hyde
For a long time nitrate has been viewed warily, with previous research showing it could potentially be linked to causing cancer. However, it has subsequently bee revealed to have various cardiovascular health benefits. So, which is it? A new review of …
