Phys.org / Why no individual is like another when epigenetics come into play
Why do animals behave differently, and what are the consequences of this? A research team from the Collaborative Research Center NC³ at Bielefeld University and the University of Münster now provides a new explanation: epigenetic ...
Tech Xplore / Bat-inspired ultrasound helps palm-sized drones navigate fog and smoke
A team led by Worcester Polytechnic Institute (WPI) researcher Nitin J. Sanket has shown that ultrasound sensors and a form of artificial intelligence (AI) can enable palm-sized aerial robots to navigate with limited power ...
Medical Xpress / Not just boys: The overlooked story of ADHD in women and girls
When people think about attention-deficit/hyperactivity disorder (ADHD), they often picture a hyperactive young boy running around a classroom, not the quiet girl daydreaming in the corner, the chatty student who can't finish ...
Phys.org / Hubble revisits Crab Nebula to track 25 years of expansion
Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 light-years ...
Tech Xplore / Video-based AI gives robots a visual imagination
In a major step toward more adaptable and intuitive machines, Kempner Institute Investigator Yilun Du and his collaborators have unveiled a new kind of artificial intelligence system that lets robots "envision" their actions ...
Phys.org / Astronomers discover 87 stellar stream candidates in the Milky Way
Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. ...
Phys.org / Sediment core reveals 10,800 years of precipitation history in the Sahara
The analysis of a sediment core from an oasis lake in Chad provides new insights into the history of precipitation in the Sahara. The study, led by the University of Cologne, shows that a prolonged wet phase, which lasted ...
Medical Xpress / When it comes to surgery, your doctor's leadership skills play a crucial role
You're scheduled for surgery next week. You've likely looked up your surgeon's credentials, years of experience, and perhaps even patient reviews. You want reassurance that your surgeon has steady hands, deep expertise, and ...
Phys.org / Shift in key cosmic inflation measurement could be a statistical artifact
For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big ...
Phys.org / A solar system in the making? Two planets spotted forming in disk around young star
Astronomers have observed two planets forming in the disk around a young star named WISPIT 2. Having previously detected one planet, the team has now employed European Southern Observatory (ESO) telescopes to confirm the ...
Medical Xpress / Astrocytes in the amygdala may play a key role in anxiety
In a study published in Neuron, Ciaran Murphy-Royal, researcher at the Center de recherche du Center hospitalier de l'Université de Montréal (CRCHUM), and his team show that astrocyte activity in the brain's fear center, ...
Phys.org / Boron arsenide semiconductor sets record in quantum vibrations
You may not be able to hear it, but all solid materials make a sound. In fact, atoms—bound in lattices of chemical bonds—are never silent nor still: Under the placid surface of each and every object in our surroundings, a ...
