Phys.org / Fusion reactors could be monitored for covert plutonium production
In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly ...
Dialog / 'Contaminated' cultures: Can conservation protect nature while excluding Indigenous peoples?
At an international heritage symposium in Japan, I heard a word that stayed with me: "contaminated." The discussion concerned whether Indigenous peoples needed to be named explicitly in a new World Heritage framework. One ...
Phys.org / Dark matter cannot be ruled out as cause of gamma ray glow at the Milky Way's center, machine learning shows
An international research collaboration between the University of Vienna and Lawrence Berkeley National Laboratory in the United States has used machine learning to re-examine one of the most debated signals in astrophysics. ...
Phys.org / Comb jelly embryos reveal embryonic signaling center shared across early animal evolution
In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, left and right, and ...
Medical Xpress / Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death
Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type ...
Tech Xplore / Milan hospital tests 1.2-meter robot to fetch water and relay patient needs
A robot with expressive eyebrows designed to perform basic tasks and free up health care workers is getting a trial run at a hospital in Milan.
Medical Xpress / Pakistani genomes reveal 34,000 knockouts that could explain why mouse-based drugs fail in humans
A comprehensive analysis of 173,303 genomes from Pakistan, published today in Nature, is upending how scientists understand human genetics and drug development. By identifying 34,000 people who are "human knockouts," with ...
Tech Xplore / Electric 'nose' can smell when your food's gone bad
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. ...
Phys.org / LOFAR reveals spike-like repeating radio burst pairs in the solar corona
The solar atmosphere is a turbulent and magnetized environment, with the release of magnetic energy readily manifesting as emission across the electromagnetic spectrum. Solar radio emission dominates the radio sky, with the ...
Phys.org / Superconducting TES array X-ray spectrometer goes into operation at BESSY II
Europe's first and only TES spectrometer at a synchrotron source is now in operation at BESSY II, developed within a collaboration between the HZB, the MPI-CEC (Mühlheim-an-der-Ruhr, Germany) and the NIST (Boulder, Colorado, ...
Medical Xpress / Why don't some people get vaccinated? It's more complicated than you think
When vaccination rates drop—as is the case with adult influenza vaccinations in Canada and child measles vaccinations in British Columbia—the explanation is often that people are "hesitant."
Phys.org / Thawing permafrost may trigger overlooked carbon sink in rivers
A new study published in Nature shows that rock weathering increasingly counteracts river CO2 emissions as permafrost degrades. The study was carried out by a collaborative team of researchers from Umeå University in Sweden ...
