Medical Xpress / Smelling freshly brewed coffee briefly improves mood, small study suggests
For millions around the globe, a freshly brewed cup of coffee is a wake-up drink first thing in the morning and a pick-me-up during a long, tedious workday. Scientists now have clues that it might be more than just the boost ...
Tech Xplore / Real-world EV data reveal how uneven cell aging shortens battery lifespan
Electric vehicles (EVs), including cars, buses and trains, could significantly reduce the substantial greenhouse gas emissions produced by the transportation sector. These vehicles' performance and reliability over time, ...
Phys.org / Newly discovered orange killifish in the Brazilian Amazon may already be endangered
Researchers have discovered a new species of brilliantly colored fish from a network of forest streams in the Brazilian Amazon and have already recommended it for listing as Endangered because of the pressures facing its ...
Tech Xplore / Consumer camera modification offers low-cost way to assess solar cell performance
Commercial cameras can be powerful, producing images with exquisite detail that mimic real life. In the lab, specially designed cameras can photograph objects in the infrared region, invisible to the naked eye.
Phys.org / Gold nanoplasmonic chip tracks L-DOPA response in Parkinson's 'mini-brains'
Researchers have developed an organoid-on-a-chip technology that verifies the efficacy of Parkinson's disease treatments in real time. The technology combines a stem cell–derived "mini-brain" with a nanoplasmonic sensor engineered ...
Phys.org / A 42-light-year X-ray tail links a pulsar to previously 'orphan' gamma rays
Understanding the origin, acceleration and propagation of high-energy cosmic rays has been a century-old mystery in astrophysics. Recently, joint observations from China's Einstein Probe (EP) satellite and the Large High ...
Medical Xpress / Immune cells that may help sustain type 1 diabetes attack identified
Type 1 diabetes isn't an overnight attack against the body's ability to make insulin. It can be a sustained campaign over years that relentlessly targets insulin-producing cells in the pancreas. Scientists have not fully ...
Medical Xpress / Why repeated exposures may make allergies worse
A new preclinical study led by investigators from Mass General Brigham offers a potential explanation for two longstanding questions in allergy: Why do allergies often emerge only after repeated exposure, and why do people ...
Medical Xpress / 'Reporter game' helps regulate sensory-brain activity in autistic youth, MRI study finds
For many autistic children, everyday sensations such as the feel of scratchy fabric or a loud car alarm can be intensely distressing. Known as sensory over-responsivity, this common symptom can affect all aspects of everyday ...
Phys.org / Liquid crystal takes page from steel in surprising phase transition
A type of transformation best known for hardening steel and enabling shape-memory alloys may also occur in a much softer class of materials, according to new research from Rice University. Researchers in the departments of ...
Medical Xpress / When the eyes play tricks, the brain builds consensus
Have you ever seen something that doesn't quite add up? Maybe a shape in the dark resembles a face, or an orange momentarily looks like an apple. Scientists now have a new idea about how different brain regions may work together ...
Phys.org / Circular mRNA helps cell factories make up to six times as much protein
A synthetic biology technology has been developed that converts easily degraded messenger RNA (mRNA) into a ring-shaped form inside microbial cells, increasing protein production.
