Phys.org / Supernova origins explored through primordial black holes
Dr. Shing-Chi Leung, assistant professor of physics at SUNY Polytechnic Institute, has published the article "Primordial Black Hole Triggered Type Ia Supernovae II: Comparison with Supernova Remnants and Galactic Chemical ...
Phys.org / Mountain lions have major ecological impact even in small preserves
Big cats have a big impact. A long-term study showed that when mountain lions began regular visits to a small suburban preserve about 45 miles (72 kilometers) south of San Francisco, they changed the behavior of many other ...
Phys.org / A 19-year 'goldmine' of mountain cloud and rainwater samples provides fresh insights about air pollution
Rainfall history is just as critical to predicting air pollution as where the air came from, a team led by University of Michigan Engineering researchers, in collaboration with scientists at the Appalachian Mountain Club ...
Phys.org / Mars mission simulations reveal key to teamwork under pressure
Whether it's to the moon or Mars, a NASA mission requires some essential preparations: designing and developing the spacecraft, astronaut training and safety checks, clear goals, and strategies and procedures for maintaining ...
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 / 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 ...
Phys.org / Drug-free nanoparticles stop tumor growth by transmitting biological messages to immune cells
A research team from the Technion's Wolfson Faculty of Chemical Engineering has developed an original technology for treating cancer using nanoparticles that carry no drugs at all and has demonstrated its effectiveness against ...
Phys.org / Dozens of active dust devils caught swirling across Mars canyon system
The European Space Agency's Mars Express has captured part of Mars's Mamers Valles, a fascinating valley system speckled with brief, tornado-like whirlwinds known as dust devils.
Phys.org / Radar echoes from Europa reveal secrets beneath the ice
A team of scientists has used NASA's Goldstone Solar System Radar and the U.S. National Science Foundation Green Bank Telescope (NSF GBT) to carry out the most extensive radar study to date of Europa, the ocean world orbiting ...
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, ...
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 / 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. ...
