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 CISOs break down complex security challenges
The role of the CISO has evolved into a critical position that encompasses many responsibilities aimed at safeguarding digital assets, preserving data integrity, and mitigating cyber threats. In essence, the role of the CISO is a complex and ever-evo.....»»
Study explains how part of the nucleolus evolved
Inside all living cells, loosely formed assemblies known as biomolecular condensates perform many critical functions. However, it is not well understood how proteins and other biomolecules come together to form these assemblies within cells......»»
Elephant ancestors" teeth evolved in response to long term changes in diet and climate in Africa
The latest study about of proboscideans (elephants and their ancient relatives) from the University of Helsinki provides proof that some proboscideans started to adapt to locally grass-rich environments in East Africa first by changing their behavior.....»»
"Wolverines really need Colorado": Federal decision looms over another reintroduction plan
The mountain devil can cross hundreds of miles of rough alpine terrain, tear into an elk carcass frozen for weeks and fend off predators several times larger than its 40-pound frame......»»
Getting protein factories to run—How deubiquitinating enzymes moonlight as Fubi proteases
The small protein ubiquitin is particularly famous for marking proteins for degradation but it has also been shown to regulate virtually all cellular processes. In parallel to the ubiquitin system various other ubiquitin-like modifiers have evolved,.....»»
Alien invasive species in Australia
Since the break-up of Gondwana, Australia's biodiversity has evolved mostly in isolation from the rest of the world. Many of our species are unique to Australia......»»
Pivotal discovery in sensor technology eliminates faulty electronic sensors when measuring toxins in water
There is a global water crisis, and it is not only about the dwindling supply of clean water. Contaminated drinking water exposes hundreds of millions of people worldwide to toxins, such as bacteria, heavy metals, pesticides and coronaviruses. This c.....»»
Novel algorithm able to detect mutations in single-cell sequencing data sets
Single-cell RNA sequencing data are useful for studying cell phenotypes and function. However, deciphering the clonal relationships of cells is critical to understanding the patterns of cell migration during development and tissue growth, and to stud.....»»
Top fish predators could suffer wide loss of suitable habitat by 2100 due to climate change
A study of 12 species of highly migratory fish predators—including sharks, tuna, and billfish such as marlin and swordfish—finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in th.....»»
Common ancestors of bats were omnivorous, according to resurrection of ancestral sweet receptors
The origins of powered flight and laryngeal echolocation in bats are widely cited as evidence that ancestral bats evolved as insectivores. Moreover, others have hypothesis that suggesting early bats were diurnal herbivores and that insectivory emerge.....»»
Understanding the role of sociality and implications for disease transmission among bighorn sheep populations
Sociality plays a pivotal role in the lives of many animal species, influencing mating success, survival rates, and susceptibility to diseases. In the challenging environment of bighorn sheep populations, sociality is believed to have evolved for its.....»»
Current estimates of Lake Erie algae toxicity may miss the mark
There is more to a harmful algal bloom than the green stuff in water that meets the eye—specifically, a changing hazard level of toxins produced by the microbes that make up the scummy mess......»»
Scientists discover how trilobites survived environmental change
Scientists have worked out how one unusual species of trilobite—an ancient, sea-dwelling relative of spiders and lobsters—was able to defend itself against predators and survive a bumpy ride as Earth's oxygen levels fluctuated......»»
Cats first finagled their way into human hearts and homes thousands of years ago—here"s how
A few years ago, I had the opportunity to go on safari in southern Africa. One of the greatest thrills was going out at night looking for predators on the prowl: lions, leopards, hyenas......»»
iOS 17 lets users create Shortcuts actions to open specific Camera app modes
Apple’s Shortcuts app has evolved a lot since the company acquired Workflow in 2017. For those unfamiliar, it lets users create a series of automated processes on iPhone, iPad, Mac, and even Apple Watch. And with iOS 17, Apple is adding even more f.....»»
Bees likely evolved from ancient supercontinent, earlier than suspected
The origin of bees is tens of millions of years older than most previous estimates, a new study shows......»»
Mutation accessibility fuels influenza evolution
The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children's Research Hospital have added a new layer of understanding to explain why and how flu viruses c.....»»
Are "Cocaine Sharks" Really Scarfing Down Drugs off Florida"s Coasts?
With their stealth, speed and serrated teeth, sharks are predators to be reckoned with. And that’s before factoring in the cocaine some sharks may be eating.....»»
Fossil skulls alone cannot predict if animal was warm blooded, study finds
The ability of most mammals to maintain a relatively constant and high body temperature is considered a key adaptation, enabling them to successfully colonize new habitats and harsh environments. Eager to determine how this ability evolved, some scie.....»»
Study: 800 great white sharks have visited Cape Cod in recent years
A new population study of great white sharks off Cape Cod shows that the region is one of the largest white shark hotspots in the world, as the apex predators flock to the Cape to hunt seals......»»
