The National Oceanic and Atmospheric Administration has global climate records dating back 174 years.  As the planet continues to heat up, both September and October set new records as the warmest of those months in history. September was the fourth month in a row of record-warm global temperatures.  Not only was it the warmest September […]

Researchers at University of California Riverside have been studying how to enable plants to sense and react to a chemical in the environment without damaging their ability to function in all other respects.  Why do this?  The idea is to be able to use plants as environmental sensors that can detect the presence of harmful […]

A spore-producing bacterium is the source of various crystal toxins (known as Cry proteins) that are widely used in modern agriculture to combat insect pests – generally caterpillars and other larvae – that attack important crops.  Pest control in corn, soybean, and cotton use these insecticidal proteins for protection against major insect pests.  The pesticides […]

When ocean waters get too warm, corals – which are actually tiny animals – eject the colorful algae that inhabit their tissues.  The symbiotic relationship between coral polyps and algae is essential to coral survival   When the algae is ejected, previously colorful coral turns white, and the coral can ultimately die.  If waters cool off, […]

The numbers of elephants, rhinos, and other animals in Uganda’s nature preserves is steadily improving, reversing the trend of steady declines previously caused by poachers, wildlife traffickers, and conflict. Between the 1960s and 1980s, political conflict and lawlessness in Uganda led to massive declines in some species as poaching, trafficking, and encroachment ran rampant. Uganda’s […]

PFAS – per- and polyfluoralkyl substances – are a group of organic compounds that have been extensively used to provide water-, oil-, and dirt-resistance to a wide range of products ranging from non-stick pans, clothing, and packaging to paint, car polish, and fire-suppressant foam.  Exposure to specific PFAS compounds is associated with multiple adverse health […]

The food industry generates enormous amounts of waste and by-products.  Each year, 40 million tons of chicken feathers are incinerated, causing adverse environmental effects.  Not only does it release large amounts of carbon dioxide but also produces toxic gases such as sulfur dioxide. Researchers at ETH Zurich in Switzerland and Nanyang Technological University in Singapore […]

Airplanes have been around for over a century, but the idea of powering them with electricity rather than with liquid fuels has been little more than a fantasy.  Over the years, billions of dollars have been invested trying to make electric planes practical.  In recent times, progress on battery technology has provided a much-needed boost […]

Many of us buy blueberries, raspberries, blackberries, and more in those little clear plastic clamshell boxes.  We try to check them out at the store to make sure they are ok and even if are, many soon end up coated with gray mold and other fungi.  It is a problem that is both disappointing and […]

Birds face a wide range of dangers.  Billions of them each year face violent deaths.  Concerned individuals point at such things as wind turbines, which in fact do kill hundreds of thousands of birds.  But the great majority of bird deaths are caused by cats.  And that’s a danger that isn’t going to go away.
