Monarchs evolved mutations to withstand milkweed toxins; so did their predators
Monarch butterflies and their close relatives thrive on poisonous milkweed, thanks to genetic mutations that block the effects of the plant's toxins while allowing the poisons to accumulate in the caterpillar or adult insects as deterrents to hungry.....»»
How hunting may have turned humans into long-distance runners
Researchers have discovered hundreds of historical accounts of humans hunting prey by chasing them down over long distances, which some believe is why we evolved our unique talent for endurance running......»»
Beethoven likely didn’t die from lead poisoning, new hair analysis reveals

Dice snakes found to use a variety of techniques to more effectively fake their own deaths
A pair of biologists at the University of Belgrade, in Serbia, has found that dice snakes use a variety of techniques to fool predators into believing they have died. In their paper published in the journal Biology Letters, Vukašin Bjelica and Ana G.....»»

Making seagrass restoration more resistant to rising temperatures using generalist grasses
New research demonstrates that seagrass habitat restoration can be enhanced by including other grasses in addition to the declining or lost species and—ultimately—that restoration efforts must proactively select species that can withstand current.....»»
Researcher finds that wood frogs evolved rapidly in response to road salts
When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research published in Ecology and Evolution a team led by Rick Relyea, Ph.D., professor of biological sciences and David M. Darrin Senior Endowed.....»»
Evolutionary biologists show that the color variants of female cuckoos are based on ancient mutations
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morp.....»»
A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. How did that come a.....»»
Bioluminescence first evolved in animals at least 540 million years ago, pushing back previous oldest dated example
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study from scientists with the Smithsonian's National Museum of Natural History......»»
Star bars show universe"s early galaxies evolved much faster than previously thought
The universe's early galaxies were less chaotic and developed much faster than previously thought, according to new research looking back more than ten billion years in time. An international team of astronomers led by Durham University, UK, has used.....»»
New models of Big Bang show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they've hypothesized the existence of "dark matter," which would be invisible to conventional forms of observ.....»»
Soil bacteria link their life strategies to soil conditions: Study
Soil bacteria help regulate the cycling of carbon and nutrients on Earth. Over time, these bacteria have evolved strategies that determine where they live, what they do, and how they deal with a changing environment. However, microbiologists do not f.....»»
Queen bumblebees surprise scientists by surviving underwater
Bumblebees can surprisingly withstand days underwater, according to a study published Wednesday, suggesting they could withstand increased floods brought on by climate change that threaten their winter hibernation burrows......»»
New time-resolved ultraviolet photodissociation mass spectrometry strategy for target protein stability analysis
How mutations impact protein stability and structure dynamics is crucial for understanding the molecular mechanism of the disease and the targeted drug design. However, probing the molecular details of mutation-induced subtle structure dynamics is st.....»»
iOS features that get progressively more useful [Video]
The iPhone and iOS have continuously evolved over the last 17 years. When the original iPhone was released, the feature sets and tools included in PhoneOS 1 were very limited. Apple wanted users to focus on basic interactions such as using the new to.....»»
More than two dozen Colorado water systems exceed EPA"s new limits on "forever chemicals"
Twenty-nine of the more than 2,000 water treatment facilities in Colorado do not meet strict new federal limits on the amount of dangerous "forever chemicals" in their drinking water supplies and it will cost millions to clean those toxins out of the.....»»
The House TikTok Ban Is an Empty Threat
There's no way that the House's attempted TikTok ban can withstand First Amendment scrutiny. Last month, the House of Representatives proudly voted to ban TikTok unless its corporate parent sells the app within six months. But propo.....»»

Study explores changing design of birdfeeders as influenced by unwanted guests
The first birdfeeders were made in the 19th century, and their design rapidly evolved during the 20th century. Researchers at the University of Helsinki and Aalto University consider the evolution of the birdfeeder to be an example of multispecies de.....»»
