Phys.org / Why Aristotle would hate Valentine's Day, and his five steps to love
Valentine's Day is traditionally a time of heart-shaped balloons, overpriced roses and fully booked restaurants. Couples kiss and hold hands, smiling selfies celebrate a day of public displays of devotion.
Medical Xpress / No association between mRNA COVID-19 vaccination during pregnancy and autism in children, new research shows
The mRNA COVID-19 vaccine is not associated with autism or other neurodevelopmental problems in children whose mothers received the vaccine immediately before or during pregnancy, according to new research presented today ...
Phys.org / Green or not, US energy future depends on Native nations
The Trump administration's drive to increase domestic production of fossil fuels and mining of key minerals likely cannot be accomplished without a key constituency: Native nations.
Phys.org / How a tiny shrimp could hold the clue to better armor
Modern armor systems do not do a good enough job of protecting humans from blast-induced neurotrauma (brain and eye damage). To improve them, we may have to look to nature. In particular, a tiny shrimp that is able to protect ...
Phys.org / Ammonia leaks can be spotted in under two seconds using new alveoli-inspired droplet sensor
Researchers from Guangxi University, China have developed a new gas sensor that detects ammonia with a record speed of 1.4 seconds. The sensor's design mimics the structure of alveoli—the tiny air sacs in human lungs—while ...
Phys.org / A new way to 'cage' plutonium
Plutonium (Pu) exhibits one of the most diverse and complex chemistries of any element in the periodic table. Since its discovery in 1940, scientists have synthesized and studied many different types of plutonium-containing ...
Phys.org / New experiments suggest Earth's core contains up to 45 oceans' worth of hydrogen
Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's suspected to be a major ...
Phys.org / Strike against mask wearing in 1930s echoed COVID-19 protests, study finds
New research from The University of Manchester has shown that debates and resistance about wearing face masks go back a lot further than the COVID-19 pandemic. Dr. Meng Zhang, a Wellcome Trust Research Fellow at the University's ...
Tech Xplore / Toward regenerative bioprinting: Magnetic mixer enables scalable manufacturing of 3D-printed tissues
3D bioprinting, in which living tissues are printed with cells mixed into soft hydrogels, or "bio-inks," is widely used in the field of bioengineering for modeling or replacing the tissues in our bodies. The print quality ...
Phys.org / The origin of magic numbers: Why some atomic nuclei are unusually stable
For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based directly on the interactions between their protons and neutrons. Published in Physical Review Letters, ...
Phys.org / NOvA maps neutrino oscillations over 500 miles with 10 years of data
Neutrinos are very small, neutral subatomic particles that rarely interact with ordinary matter and are thus sometimes referred to as ghost particles. There are three known types (i.e., flavors) of neutrinos, dubbed muon, ...
Phys.org / Subaru observations suggest an intrinsic gap in NGC 5466's tidal stream
Astronomers from the National Astronomical Observatory of Japan (NAOJ) and elsewhere have used the Subaru Telescope to perform deep imaging observations of a distant globular cluster known as NGC 5466. The observational campaign ...
