Modern birds are the living relatives of dinosaurs. Take a look at the features of flightless birds like chickens and ostriches that walk upright on two hind legs, or predators like eagles and hawks with their sharp talons and keen eyesight, and the similarities to small theropod dinosaurs like the velociraptors of Jurassic Park fame are striking. Yet birds differ from their reptile ancestors in many important ways. A turning point in their evolution was the development of larger brains, which in turn led to changes in the size and shape of their skulls. New research from ...

Iguanas have often been spotted rafting around the Caribbean on vegetation and, ages ago, evidently caught a 600-mile ride from Central America to colonize the Galapagos Islands. But for long distance travel, the Fiji iguanas can't be touched. A new analysis conducted by biologists at the University of California, Berkeley, and the University of San Francisco (USF) suggests that sometime after about 34 million years ago, Fiji iguanas landed on the isolated group of South Pacific islands after voyaging 5,000 miles from the western coast of North America — the longest known transoceanic dispersal of any terrestrial vertebrate. Overwater ...

UNIVERSITY PARK, Pa. — It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without wearing headphones. In a new advancement in audio engineering, a team of researchers led by Yun Jing, professor of acoustics in the Penn State College of Engineering, has precisely narrowed where sound is perceived by creating localized pockets of sound zones, called audible enclaves. In an enclave, a listener can hear sound, while others standing nearby cannot, even if the people are in an enclosed space, like a vehicle, or standing ...

By taking two flakes of special materials that are just one atom thick and twisting them at high angles, researchers at the University of Rochester have unlocked unique optical properties that could be used in quantum computers and other quantum technologies. In a new study published in Nano Letters, the researchers show that precisely layering nano-thin materials creates excitons—essentially, artificial atoms—that can act as quantum information bits, or qubits. “If we had just a single ...

Backgrounds and objectives Gastrointestinal complications are common in patients after ischemic stroke. Gastric motility is regulated by gastric pace-making activity (also called gastric myoelectrical activity (GMA)) and autonomic function. The aim of this study was to evaluate GMA, assessed by noninvasive electrogastrography (EGG), and autonomic function, measured via spectral analysis of heart rate variability derived from the electrocardiogram in patients with ischemic stroke. Methods EGG and electrocardiogram were simultaneously recorded in both fasting and postprandial states in 14 patients with ischemic stroke and 11 healthy controls. ...

Trial of strength at the cellular level: cells are in constant competition with each other and so eliminate diseased or unwanted cells. Cell competition is therefore a central principle for maintaining the health of tissues and organs. Researchers have investigated the success factors of superior cells and discovered a previously unknown winning strategy in mechanical cell competition. They identified a variety in the ability of cells to exert mechanical forces onto other cells as the decisive regulator. With their results ...

On first inspection, the Cuban blue-headed quail dove doesn’t look like much: drab brown feathers, a slender beak, a pronounced strut in their walk typical of most other doves. You’d be forgiven for overlooking it in favor of Cuba’s prismatic parrots. But looks aren’t everything. For decades, this unassuming bird has perplexed biologists, who have no idea where it came from, how it got to the island or what it’s related to. Now, for the first time, scientists have sequenced DNA from the blue-headed quail dove with the goal of finally getting to the bottom of things. Instead, they’re even more perplexed now than when they started. “This ...

Researchers have widely accepted that what sets humans apart from nonhuman primates are prefrontal cortex–driven behaviors such as decision-making, reasoning, planning, and attention. In a new JNeurosci paper, research led by Rogier Mars, at University of Oxford, and Katherine Bryant, at Aix-Marseille University, provides a better picture of the cortical evolution that distinguishes human brains from other primates.   The researchers compared cortical organization not only between humans and macaques, which is a standard for human and nonhuman primate ...

How stress impacts behavioral outcomes of traumatic brain injury (TBI) represents a major gap in knowledge. This oversight is especially felt by those in the military due to the high prevalence of TBI and the abundance of stress that they endure. In a study funded by the US Department of Defense, researchers led by Pamela VandeVord at Virginia Tech discovered that prior stress exposure influences TBI outcomes in a sex-dependent manner.   In their eNeuro paper, VandeVord and colleagues used an unpredictable stress paradigm ...

MIAMI, FLORIDA (EMBARGOED UNTIL MARCH 17, 2025, AT NOON EDT) – Glioblastoma has remained one of the toughest cancers to treat, resisting even the latest advances in immunotherapy. But new research from Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, suggests a way forward: suppressing a protein called ZNF638 triggers an antiviral immune response, making immune checkpoint inhibitors more effective. The discovery not only offers a potential new treatment strategy but also identifies ...

In a randomized trial, Mass General Brigham researchers found the surgical removal of tonsils and adenoids was effective for children with snoring and mild sleep apnea An estimated 6 to 17 percent of children have sleep-disordered breathing, ranging from snoring to sleep apnea, which can cause behavioral, neurocognitive, cardiovascular, and cardiometabolic issues. A new study from Mass General Brigham researchers reveals that adenotonsillectomy—the surgical removal of tonsils and adenoids—is an effective early intervention for these children. Their results are published in JAMA Pediatrics. “To ...

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation studies. The observations provide strong evidence that the system’s four giant planets formed in much the same way as Jupiter and Saturn, by slowly building solid cores. They also confirm Webb can do more than infer atmospheric composition from starlight measurements—it can directly analyze the chemistry ...

A National Institutes of Health (NIH)-sponsored clinical trial of a candidate vaccine to prevent Lassa fever has begun enrolling participants at the University of Maryland School of Medicine, Baltimore. Lassa fever is a viral hemorrhagic disease that can be fatal and that causes permanent hearing loss in up to one-third of those who contract it. Lassa virus is spread by rodents, known as multimammate rats, that are native to many countries in West Africa. The virus can also be spread from person to person. Currently, there are no specific drug treatments or vaccines for Lassa fever. NIH’s National Institute of Allergy and ...
