Grocery stores that donate expiring food instead of price discounting or discarding make higher profits, says researcher
All major supermarkets and retailers that sell groceries, such as Kroger, Walmart and Costco, give large amounts of food to food banks and pantries. In 2022, retailers donated close to 2 billion pounds of food across the United States, which amounted.....»»
How to save a sinking city
What do Venice, Jakarta, Manilla and Bangkok have in common? They are or were sinking cities. Wageningen researcher Philip Minderhoud studies the causes of subsidence in these cities. Groundwater extraction plays an important part in all cases. The g.....»»
Satellite data fusion enhances the early detection of convective clouds
As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a chall.....»»
How old is beer?
Humans are no strangers to kicking back with a cool pint of beer. The Ancient Egyptians, for example, had a hankering for beer that was a little bit tart, almost like a modern-day gose, a lemony beer from Germany. Homer, the Ancient Greek poet, spoke.....»»

Researchers explore novel approach to map forest dieback in satellite images
Forests and woodlands cover one third of Earth's surface and play a critical role in carbon sequestration, water regulation, timber production, soil protection, and biodiversity conservation. Accelerated by climate change, the decline of these and ot.....»»
Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Researcher develops low-sugar ice cream with smooth texture
Wageningen researcher Qi Wang has developed a new variant of low-sugar ice cream that mimics the texture and melting properties of traditional ice cream. By replacing half of the sugar with broken-down proteins or the sweetener xylitol, she succeeded.....»»
Climate change is easier to study when it"s presented as a game, says researcher
Climate change is among the more difficult but important topics to teach to young people. It involves complicated science and data, and it can be really depressing, given the bleak picture it paints of Earth's future......»»
Study shows that ancient reef-building stromatoporoids dodged extinction—at least temporarily
Will modern coral reefs go extinct? The answer is uncertain, but some of their ancient counterparts managed to dodge a bullet—for a while, at least......»»

Medicinal tree successfully grown from 1,000-year-old seed found in cave
An international team of botanists, agriculturists and historians has successfully grown a mature tree from an ancient seed found in a cave in Israel. In their paper, published in the journal Communications Biology, the group describes where the seed.....»»
Afar mantle plume study offers new insight into deep Earth processes
Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth......»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»
