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 / 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 / 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 ...
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 / El Nino may return in 2026 and make planet even hotter
The warming El Niño weather phenomenon could form later this year, potentially pushing global temperatures to record heights.
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 / 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 / Antarctica has lost 10 times the size of Greater Los Angeles in ice over 30 years, satellite data reveal
A comprehensive 30-year study led by University of California, Irvine glaciologists has produced a circumpolar ice grounding line migration map of Antarctica. An amalgamation of three decades of satellite data compiled and ...
Phys.org / How to train your catalyst, one atom at a time
How do you keep a copper catalyst from losing its oomph? Just add a dusting of platinum, says a new study published in Nature Materials. A team of researchers, including scientists at the Department of Energy's SLAC National ...
