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 ...

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 ...

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 / 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 ...
