“Mona Lisa effect” applies to animals too
Chick experiments hint at why eyespots evolved independently in different species. Enlarge / A peacock butterfly (Aglais io) has eyespots on the upper surface of each forewing and hindwing that appear to look you in the eyes—a percep.....»»
Synthetic modules boost production of animal-based nutrients in plants
It's important to eat your veggies, but some essential vitamins and nutrients can only be found in animals, including certain amino acids and peptides. Now, in a proof-of-concept study published in the Journal of Agricultural and Food Chemistry, rese.....»»
Pollination shifts in Caribbean after Hurricane Maria demonstrate ecological resilience
Most flowering plants depend on animals for pollination. In warm wet tropical regions, more than 90% of plant species are pollinated by animals. In Dominica, a Caribbean island country, researchers have identified a mutualistic relationship between t.....»»
Breeder who tried to create enormous trophy sheep jailed in US
A man who tried to breed enormous hybrid sheep using genetic material from endangered animals so he could sell them to trophy hunting ranches has been sentenced to six months in prison, the US Department of Justice said Monday......»»
"Vegetarian" possums eat meat when the weather"s cold
When dead animals are left lying around in nature, who takes advantage of the free feed—carnivores or herbivores? The answer may surprise you......»»
Reading desert sands—Indigenous wildlife tracking skills underpin vast monitoring project
As animals move across the desert, they leave tracks, diggings and droppings. For skilled trackers, reading these signs is like watching a movie. A story of who was there and what they were doing unfolds in front of them......»»
Wall lizards shed light on how animals prevent harm in territorial disputes
A study appearing in Behavioral Ecology shows that in male wall lizards, certain behaviors have a greater influence on the way they resolve territorial disputes than their size and coloration......»»
Genetic rescue for rare red foxes? Research uncovers options to restore Lassen red fox population
A rescue effort can take many forms—a life raft, a firehose, an airlift. For animals whose populations are in decline from inbreeding, genetics itself can be a lifesaver......»»
Scientists uncover a critical component that helps killifish regenerate their fins
Spontaneous injuries like the loss of a limb or damage to the spinal cord are impossible for humans to repair. Yet, some animals have an extraordinary capacity to regenerate after injury, a response that requires a precise sequence of cellular events.....»»
Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
Sound provides new information about the secret lives of sperm whales
Sperm whales are the loudest animals on Earth and rely on sound to find food in the sprawling darkness of the deep sea. MBARI technology allows us to listen in, gaining new insight into the mysterious lives of these animals......»»
Humbug damselfish use "motion dazzle" to evade predators
When thinking of animal camouflage, we typically imagine creatures remaining still, blending seamlessly into their surroundings. But remaining motionless isn't always practical, and many animals are highly mobile, constantly moving through their envi.....»»
Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
A new genetic analysis of animals in the Wuhan market in 2019 may help find COVID-19"s origin
Scientists searching for the origins of COVID-19 have zeroed in on a short list of animals that possibly helped spread it to people, an effort they hope could allow them to trace the outbreak back to its source......»»
New biosensor illuminates physiological signals in living animals
Eric Schreiter and Luke Lavis thought they had figured it out. In 2021, the Janelia group leaders reported that they had developed a way to combine Schreiter's engineered protein biosensors and Lavis's bright, fluorescent Janelia Fluor dyes......»»
Physicist reveals tailwind has negligible effect on cycling speed
Within the cycling realm, "to Everest" involves riding up and down the same mountain until your ascents total the elevation of Mt. Everest—8,848 meters......»»
Female elephants rumble to say "let"s go!" Namibian study shows males do too, a sign of unexpected social bonds
In elephant family groups made up of related females and their young, it is clear that the animals produce vocal sounds to coordinate action. This happens when it's time to leave a waterhole, for example. The matriarch or dominant female steps away f.....»»
