The unraveling of the shrew, in winter: Studies decode genetic basis of seasonal organ shrinkage in mammals
Some mammals hibernate to survive in winter, but the Eurasian common shrew (Sorex araneus) employs Dehnel's phenomenon to get through it. This is a metabolic process that enables shrews to conserve energy by shrinking their ...

Photosynthesis: Study reveals how minerals are involved in homeostasis of chloroplasts
Plants fix 258 billion tons of CO2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals iron (Fe), manganese ...

How play and social connection may help some dogs understand words
Some dogs are seemingly more talented than others. So-called gifted word learners (GWL) are rare canines that can rapidly learn the names of toys, a skill that most dogs don't possess. To understand why this is so, researchers ...
Ancient American pronghorns were built for speed
The fastest land animal in North America is the American pronghorn, and previously, researchers thought it evolved its speed because of pressure from the now-extinct American cheetah. But recently, that theory has come under ...

Cape Town project tests what hydroponic farming can do in urban spaces
Imagine a world where fresh vegetables and herbs sprout in the heart of our cities without the need for sprawling farms. Hydroponics—a method of growing plants without soil—uses a nutrient-rich water solution instead ...

Infrared-activated hydrogel uses lysozyme 'nets' to combat resistant bacteria
Each year, bacterial infections are responsible for roughly 7.7 million deaths worldwide, with this problem further exacerbated by rising antibiotic resistance. Not only are wound infections increasingly difficult to treat, ...

How species competition shapes trait diversity worldwide
Every ecosystem is shaped by billions of invisible battles: organisms competing for light, nutrients, space, or mates. These competitive interactions determine which species survive, how they evolve, and how vibrant and resilient ...

From sea to soil: Molecular changes suggest how algae evolved into plants
Before plants evolved, vegetative life consisted of primitive green algae living in the sea. Like plants, these algae survived by performing photosynthesis, turning sunlight into energy. However, little light reaches the ...

Are cats 'vegan' meat eaters? Why isotopic signatures of feline fur could trick us into thinking that way
Cats—unlike humans—are true carnivores: they must eat meat to survive because their bodies can't draw some essential nutrients from plants. By looking at tissues, researchers can get a good understanding of what foods ...
