Phys.org / A novel concept for a multiplanetary crewed mission to Mars and Ceres
For NASA, sending a crewed mission to Mars has been the long-term goal for over two decades. China has joined the club in recent years, with plans to send crewed missions to the red planet ahead of NASA. In both cases, the ...
Phys.org / New study discovers unexpected role of 4f-orbital covalency in driving chemical reactivity
The willingness of the 4f orbitals of lanthanide metals to participate in chemical reactions is as rare as their presence in Earth's crust. A recent study, however, witnessed the 4f orbital in a cerium-based compound actively ...
Phys.org / Century-old mystery of plant communication solved: Plants signal stress through negative pressure mechanisms
Imagine if a plant in a farmer's field could warn a grower that it needs water? Or if a farmer could signal to plants that dry weather lies ahead, thereby prompting the plants to conserve water?
Phys.org / Sea creatures keep dying in California waters: Now researchers have an answer
Sea creatures keep showing up dead in California waters, and researchers may have an answer as to why.
Medical Xpress / Scientists work toward a vaccine for filoviruses, Ebola's deadly kin
Filoviruses are among the globe's most lethal—indeed, so dangerous they can be handled only in high-security laboratories. Yet, more than five decades after the discovery of the Marburg virus and nearly 50 years after the ...
Phys.org / It's about (space-)time: Scientists explore new dimension for light
By breaking a decades-old paradigm and rethinking the role that the dimension of time plays in physics, researchers from the University of Rostock and the University of Birmingham have discovered novel flashes of light that ...
Medical Xpress / Regular chicken consumption linked to higher risk of early death from gastrointestinal cancers
A team of health researchers at the National Institute of Gastroenterology, in Italy, has found an association between regularly eating poultry and early death due to digestive system cancers. In their study published in ...
Medical Xpress / Q&A: Measles may be making a comeback in the US
Childhood vaccination rates have been falling in the United States, especially since the start of the COVID-19 pandemic. Lower levels of immunity have resulted in a resurgence of measles cases, including a recent outbreak ...
Phys.org / A possible explanation for why there is so much molecular hydrogen in space
Two materials physicists at The University of Sydney have found a possible explanation for the huge amount of molecular hydrogen in space. In their study published in the journal Communications Chemistry, Yuzhen Guo and David ...
Phys.org / World on course to trigger multiple climate 'tipping points' unless action accelerates, research warns
Multiple climate "tipping points" are likely to be triggered if global policies stay on their current course, new research shows. Scientists assessed the risk of "tipping" in 16 different parts of the Earth system—ranging ...
Tech Xplore / 'Poisoned' AI models can unleash real-world chaos; study shows how these attacks could be prevented
An unrelenting, ravenous appetite for more and more data may be artificial intelligence's fatal flaw; or at least the fastest way for "poison" to seep in.
Phys.org / Invasive weed threatens Southern California's deserts
Once thought resistant to invasion, regional deserts are losing native plants to aggressive weedy species like Saharan mustard. New research shows its spread is disrupting biodiversity and reducing the desert's ability to ...
