Phys.org / Frozen rat chromosome springs back to life inside a mouse embryo
Scientists in Japan have developed a rat-mouse hybrid embryo from a single frozen rat chromosome transplanted into a mouse egg cell. The achievement is proof that genetic material can sometimes remain functional after cryopreservation ...
Phys.org / Nickelate superconductors share a common electronic fingerprint
Superconductors, materials that conduct electricity with zero electrical resistance at specific temperature ranges, have proved very promising for the development of quantum computers and other cutting-edge technologies. ...
Phys.org / Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers laboratory-grade precision in a device ...
Phys.org / Hidden geometry explains why kernel methods separate complex data so well
Are two sets of data genuinely different, or is it because of randomness? This question, known as the two-sample testing problem, becomes notoriously difficult in modern datasets, because they are often high-dimensional, ...
Phys.org / Physicists create new family of Schrödinger-cat states
Quantum mechanics, unlike classical physics, allows objects to exist in more than one state at the same time. This idea is often illustrated by Schrödinger's cat, imagined as being both alive and dead until it is observed. ...
Phys.org / River wildlife moves freely once dams are removed, but so too can invasive species
Almost a quarter of all freshwater species are threatened with extinction. The removal of human-made barriers from rivers, such as dams and weirs, is a popular way to restore water flow and sediment transport to its natural ...
Phys.org / Ancient hominins selected basalt sources for specific tools nearly 800,000 years ago, study reveals
A new study finds that ancient hominins nearly 800,000 years ago deliberately selected specific basalt sources for different stages of tool production rather than simply using whatever stone was available nearby. By tracing ...
Phys.org / 50 years of data reveals true extent of climate change impacts on kelp forests
New research from the University of Victoria (UVic) has found that some kelp forests around Vancouver Island were disappearing far earlier than scientists previously thought, highlighting that climate change has been altering ...
Phys.org / Astronomers discover the earliest known flickering quasar
A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and ...
Phys.org / Cosmic bombardment may have opened Earth's crust for prebiotic chemistry
Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of ...
Phys.org / Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals
What do iron, lead and nickel have in common? These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats. Every day, ...
Phys.org / How Artemis II livestreamed hi-def videos and images from the moon to Earth
This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its historic journey around the moon from more than 250,000 miles (about 402,000 kilometers) back to ...
