Phys.org / 'Old Mother Goose' challenges a 14-million-year lineage story in New Zealand
The discovery of a rare fossil goose in an ancient Central Otago lake shows the evolutionary history of Aotearoa New Zealand birds is much more dynamic than once thought, a University of Otago–Ōtākou Whakaihu Waka researcher ...
Phys.org / Large land predators were hunting big plant-eaters more than 280 million years ago, study finds
A study examining fossil evidence shows that large land predators were already hunting big plant-eating animals more than 280 million years ago. University of Toronto Mississauga researchers Jordan M. Young, Tea Maho, and ...
Phys.org / 3D-printed 'plug' links fiber optics to photonic chips with low loss
Physicists and chemists at Heidelberg University have realized a photonic microchip that is driven by light just as easily as electronic components via a "plug." Their development could serve as the basis for fast and cost-effective ...
Phys.org / MeerKAT discovers record-breaking cosmic laser halfway across the universe
Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion light-years away, opening a ...
Phys.org / Dissolvable hydrogel could enable personalized bone implants
Bones broken in a skiing accident usually heal on their own. But if the break is too severe or a bone tumor needs to be removed, surgeons insert an implant that enables the bone to grow back together. Implants often consist ...
Phys.org / Are these killer whales cannibals? They probably don't think so themselves
In 2022, a Russian whale researcher made a remarkable discovery on Bering Island off Russia's Pacific coast: a severed killer whale fin marked with the teeth of another killer whale. In 2024, it happened again. The two finds ...
Phys.org / Scared of spiders? The real horror story is a world without them
Members of the arachnid class—think spiders, scorpions and harvestmen (daddy long legs)—are often the targets of revulsion, disgust and fear. Yet, they are crucial for ecosystems to thrive. Given the crash in worldwide ...
Phys.org / Agrivoltaics can increase or reduce yields and profits, depending on the crop and where the systems are deployed
In a world where increasing demands for food security and energy strain existing resources, scientists are looking for new ways to maximize both. One potential option, agrivoltaics, integrates solar photovoltaics with crops. ...
Phys.org / Ultrasound-activated 'nanoagents' kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug-delivery capsules—carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound. Delivering antibiotics ...
Phys.org / Tech upgrade reveals even finer transcription detail inside cells
In 2021, a technology developed at the University of Michigan, called Seq-Scope, revolutionized the ability to map gene activity within intact tissue at microscopic resolution, enabling researchers to measure all expressed ...
Phys.org / Smart fluorescent molecules provide cheaper path to sharper microscopy images
Multiphoton microscopy is used in biomedical research to study cells and tissues. Today, so-called two-photon microscopy is used to study processes within cells, but the technique has limitations in terms of image resolution. ...
Phys.org / Paleontologists investigate how life entered and adapted to the deep sea
The deep sea is a dark, cold place. It's just a few degrees above freezing, subject to immense pressure, and beyond the reach of the sunlight needed for photosynthesis. The life that does survive in such a hostile place must ...
