Phys.org / Light-activated medicines may cut side effects: How a switchable beta blocker works

Rendering a drug effective or ineffective in a flash at the appropriate location—this is the focus of research in photopharmacology. The goal is to develop drugs that can be switched on and off with light of a specific ...

Phys.org / H5N1 in marine mammals is spreading: Research tallies over 50,000 seals and sea lions killed along South America's coast

When the H5N1 highly pathogenic avian influenza virus was discovered on a poultry farm in Asia in 1996, there was little indication that it would become so widespread and so destructive. Within 30 years, it reached every ...

Phys.org / Invasive grasses may be turning British Columbia's burn scars into the next wildfire

After a wildfire, the flames may fade, but the danger does not. A new study by UBC researchers reveals that burned landscapes remain vulnerable for years, with large areas still bare and at risk of invasion by fast-growing, ...

Phys.org / Fluorescent dye that works in superacidic conditions expands possibilities for imaging in extreme environments

Since the 1960s, boron–dipyrromethene dyes, commonly called BODIPY dyes, have been widely used for their strong fluorescence, especially in bioimaging, molecular and ion sensing, and as photosensitizers. Researchers especially ...

Phys.org / Study uncovers mineral 'sink' that reduced phosphorus in early oceans, potentially delaying Earth's oxygen rise

Scientists have long sought to explain a key mismatch in Earth's early history: oxygen-producing photosynthesis evolved hundreds of millions of years before atmospheric oxygen began to rise during the Great Oxidation Event. ...

Phys.org / Earthquake scientists reveal how overplowing weakens soil at experimental farm

Plowing, or tilling, is an age-old agricultural practice that readies the soil for planting by turning over the top layer to expose fresh earth. The method—intended to improve water and nutrient circulation—remains popular ...

Phys.org / A water solution for drought‑prone South Africa: We designed systems to replenish aquifers

South Africa is the 30th driest country in the world. Over 400 towns, especially in the western and central parts of the country, rely on water from aquifers that they pump out of the ground (groundwater).
