Ye olde pathogen: Learning about evolution from ancient DNA
As long as humans have been around, there have been pathogens to make us sick. Some have achieved infamy in human history—the bubonic plague, for example, or smallpox—and with modern technologies, scientists can time-travel to find out what the b.....»»
Tracking a disappearing mantle plume in ancient Samoa: Researchers shed light on a 30-million-year gap
When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on the surface. Telltale hot spot tracks form as tectonic plates move over these plumes, marking plume locations and the movement.....»»
Dinosaurs thrived after ice, not fire, says a new study of ancient volcanism
201.6 million years ago, one of the Earth's five great mass extinctions took place, when three-quarters of all living species suddenly disappeared. The wipeout coincided with massive volcanic eruptions that split apart Pangaea, a giant continent then.....»»
CRISPR-Cas10 can flood virally infected bacteria with toxic molecules, researchers discover
CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision......»»

The Secret Electrostatic World of Insects
Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen, and more. New experiments explore how evolution may have influenced this phenomenon......»»
Study: DNA corroborates “Well-man” tale from Norse saga
The "Well-man" likely had blue eyes, blond or light-brown hair, and hailed from southern Norway. A 12th-century Norse saga tells of an invading army from the south razing a castl.....»»
Study reveals the twists and turns of mammal evolution from a sprawling to upright posture
Mammals, including humans, stand out with their distinctively upright posture, a key trait that fueled their spectacular evolutionary success. Yet, the earliest known ancestors of modern mammals more resembled reptiles, with limbs stuck out to their.....»»
New machine learning model quickly and accurately predicts dielectric function
Researchers Tomohito Amano and Shinji Tsuneyuki of the University of Tokyo with Tamio Yamazaki of CURIE (JSR-UTokyo Collaboration Hub) have developed a new machine learning model to predict the dielectric function of materials, rather than calculatin.....»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
Study shows weak external electric fields may protect crops from infection
Research from Dr. Giovanni Sena's group in the Department of Life Sciences highlights an intriguing method to help protect plants from pathogen attacks using weak electric fields......»»
A much faster way to encode DNA with usable digital data
An international team of molecular biologists, computer scientists and physicists has found a way to encode useable digital data onto DNA strands 350 times faster than current approaches. In their study, published in the journal Nature, the group use.....»»
Wayve, a British automated driving startup, embarks on U.S. expansion

Adapting generative AI for the next generation of learning
A new study by Monash University learning analytics researchers presents key considerations for generative AI (GenAI) educational tools so they are carefully developed to support, rather than replace, human learning......»»
Through the looking glass: A cross-chiral reaction challenges our definition of life
Just like your left and right hand exist as mirror images of each other, many biological molecules have their own form of left- and right-handedness, called chirality. Our DNA, for example, is made of right-handed chiral molecules which combine to fo.....»»
Mobile phone networks and Bluetooth technology could help researchers improve animal tracking
Animal tracking studies for ecology and conservation all face technological limitations, such as high costs or the need for tags to remain in close proximity to detectors. In research published in Methods in Ecology and Evolution, investigators descr.....»»
