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 ...
Medical Xpress / Ultrasound turns anticancer molecule into deep-lung bacteria killer
An anticancer medication called TLD1433, a ruthenium(II) complex that has entered Phase II trials for conditions such as non-muscle-invasive bladder cancer, is now being repurposed to address one of the biggest public health ...
Phys.org / Black hole feeding bursts may explain JWST's Little Red Dots in early universe
A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on ...
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 ...
Medical Xpress / How often do people pass gas? There's now an app for that
Flatulence, or farting, is something people often joke about or find embarrassing when it happens unexpectedly. It is, however, an essential bodily function that allows the digestive system to keep pressure within the intestinal ...
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 / 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 / How plants survive constant DNA damage: Newly identified repair protein protects growth-critical stem cells
Similar to the way DNA damage can contribute to human diseases such as cancer, it can also disrupt growth, development and survival in plants. Every day, plants endure environmental stresses such as sunlight, radiation, drought ...
Phys.org / Peptide blocks DNA breaks tied to treatment-induced leukemia, offering new prevention route
Thanks to effective therapies, more and more people are now able to live with or after cancer in the long term. Consequently, the number of patients affected by the long-term effects of their treatment is also increasing. ...
Phys.org / Rocket launches and reentries harm Earth's ozone layer
The space industry is surging. In coming years, nearly 10,000 spacecraft are slated to launch into low-Earth orbit for a variety of purposes, such as global surveillance, space tourism, and satellite "megaconstellations" ...
Phys.org / Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy
Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have developed a practical, comprehensive noise-modeling framework for a popular class of ...
Phys.org / Aerosols may warm or cool the climate depending on timing, new study finds
A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on ...
