In March 2021, Berkeley, Calif., became the first city in the world to ban the display of sugary beverages and snacks in store checkout lanes, where candy, chocolate and soda are commonly placed to encourage impulse buying ...
Phys.org / Dogs and cats carry antibiotic-resistant bacteria also found in people, study finds
Dogs and cats may carry strains of Klebsiella pneumoniae, a potentially serious bacterium that can cause infections and is also found in humans, according to new research from Bournemouth University published in the journal ...
Phys.org / A photon that challenges Einstein: According to current physics, it should never have reached Earth
How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been absorbed long before reaching Earth? This is the question at the heart of a new study by Giorgio ...
Phys.org / Cataract surgery will be needed in space, surgeon predicts
An eye surgeon with a passion for space since childhood predicts that as astronauts start to make journeys to the moon and Mars in the near future, eye surgery in space will eventually become a necessity.
Phys.org / Plants' response to rising CO₂ could put the brakes on dryland expansion
Drylands are defined as regions where rainfall is low relative to the atmosphere's ability to draw water from soil and plants. Expanding boundaries of these regions are frequent concerns in climate change considerations. ...
Phys.org / Asteroid Ryugu's dust reveals nitrogen's slow concentration into complex molecules
Nitrogen is a key ingredient in the biomolecules that form the building blocks of life. Yet as an unbonded gas, it is far more likely to drift into space than to lock itself into solid compounds, making it difficult for astronomers ...
Phys.org / NASA's next great observatory could spot oceans on distant worlds
We've found more than 5,500 exoplanets so far. Dozens of them are in the habitable zones of their parent stars, where, at least in theory, they could host an ocean. But we've never definitively found a liquid ocean on another ...
Medical Xpress / Amivantamab-chemotherapy demonstrates longest overall survival reported for lung cancer with EGFR mutation
Results from the phase 3 PAPILLON study show that first-line amivantamab plus carboplatin-pemetrexed (amivantamab-chemotherapy) was associated with numerically longer overall survival compared with chemotherapy in patients ...
Phys.org / How atmospheric events at the top of the world could have triggered two devastating California floods
In early 2017 and 2023, California experienced two catastrophic and record-breaking floods that caused billions of dollars in damage, triggered mudslides and forced thousands of people to evacuate. Why this happened left ...
Medical Xpress / Wound-healing peptides curb bacterial colonization in cystic fibrosis airway models
Cystic fibrosis, one of the most common genetic diseases in Switzerland, promotes chronic bacterial infections by impairing the protective barrier of the airways. Scientists at the University of Geneva (UNIGE) have discovered ...
Medical Xpress / Blood protein analysis suggests a lung disease drug could be fighting aging at the same time
In 2025, Insilico Medicine developed an experimental drug called rentosertib as a treatment for idiopathic pulmonary fibrosis, a severe age-related lung disease. The drug works by inhibiting the protein TNIK, which is involved ...
Medical Xpress / Ketamine reveals shifting brain activity patterns linked to depression improvement in older adults
Researchers at Texas A&M University's Naresh K. Vashisht College of Medicine have identified time-specific patterns of brain activity following ketamine treatment in older adults with treatment-resistant depression.
