Phys.org / NASA's proposed Early eVolution Explorer mission aims to solve the radius valley mystery
A debate has been raging among planetary scientists for more than a decade—why are there so few exoplanets with a radius of about 1.8 times that of Earth? Exoplanets are currently largely grouped into two distinct categories—"super-Earths" ...
Tech Xplore / Why asking people to rank three options could sharpen AI and recommendation systems
In his 1927 paper, "A law of comparative judgment," the American psychologist L. L. Thurstone proposed that when people select one option among multiple alternatives, they are picking the one that has the highest value to ...
Phys.org / Light-programmed system projects 28-layer 3D images in single shot
Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a ...
Medical Xpress / Megacolon: When constipation becomes something more serious
The colon is about one and a half meters long and plays a vital role in moving waste through the body. In rare cases, it can become so stretched that it begins to lose its ability to work properly, like an elastic band that ...
Phys.org / How the invention of glassblowing changed everyday life in ancient Rome
We see glass objects every day and often don't think much about them. Mass-produced glass has become so cheap we barely think about the things it allows us to do.
Medical Xpress / The press is breaking the suicide taboo but still uses stigmatizing metaphors
Suicide is a major public health concern. According to the World Health Organization (WHO), it is responsible for more than 700,000 deaths a year. In Spain, it is the leading cause of death from non-natural causes, above ...
Medical Xpress / Visceral fat loss leaves 10-year 'metabolic legacy,' cutting diabetes risk by 28% despite weight regain
Lifestyle-induced loss of visceral fat (and not liver fat, pancreatic fat or subcutaneous fat) may have lasting health benefits years after the end of an intervention, even when body weight is fully regained, according to ...
Phys.org / The hidden physics complicating interstellar lightsails
If we're to reach another star, chemical propulsion will not get us there in any reasonable time frame. We're going to need a different propulsion technology, and one of the most promising seems to be a solar sail. These ...
Phys.org / Chemical impurities make carbon surfaces superslippery, researchers find
Engineers often treat impurities as a problem to eliminate to improve material performance. But new research from Osaka Metropolitan University and Fraunhofer Institute for Mechanics of Materials IWM suggests that in some ...
Medical Xpress / Creating mini-brains from stem cells reveals a new, promising treatment for a devastating childhood disease
Variants in the DHDDS gene cause a severe neurodegenerative condition, characterized by tremors, seizures, coordination and learning difficulties, usually manifesting in early childhood. This Parkinson's-like condition is ...
Medical Xpress / Integrating genetic origin data with tumor analyses enables better prediction of survival
New research to be presented today at the annual conference of the European Society of Human Genetics shows that a cancer patient's genetic ancestry can have a significant effect both on how their disease progresses and their ...
Phys.org / Research reveals how parenting styles influence children's honesty
Parents who come down hard on their children for telling lies or misbehaving may believe they are teaching the child right from wrong. But new research by NUS suggests that overly strict or punitive parenting could be part ...
