Phys.org / Hidden mitochondrial genes emerge as mealybugs encode two genes on one DNA stretch
What if a single sentence could carry two completely different meanings, one when read forward and another when read backward? In a new study, researchers at Arizona State University have discovered a biological version of ...
Phys.org / Molecular fossils reveal secrets of Earth's recovery from ancient global warming event
Scientists have uncovered new evidence from one of Earth's most extreme ancient warming events, revealing how the climate may recover long after human-driven CO2 emissions cease.
Phys.org / Atlantic and Pacific may follow different rules on long-term warming, analysis shows
Florida State University researchers have identified key differences in the root causes of long-term sea-surface temperature changes across the Atlantic and Pacific oceans, a finding that could help guide future research ...
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 ...
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 / 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 ...
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 / 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 / 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, ...
