Phys.org / South African San rock art reveals trance dances and initiation ceremonies
In a study published in Telestes, Dr. Joshua Kumbani and Dr. Margarita Díaz-Andreu categorized the various dance scenes depicted in South African rock art, drawing on ethnographic sources, published studies, and the comprehensive ...
Medical Xpress / ADHD and methylphenidate tied to higher adult BMI
Seoul National University Hospital researchers have linked childhood attention-deficit/hyperactivity disorder and methylphenidate exposure with higher adult overweight/obesity and slightly shorter adult height at ages 20 ...
Phys.org / Breakthrough laser technique holds quantum matter in stable packets
For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions within a grid of laser light.
Phys.org / Toothbrush-activated powder whitens, repairs and protects teeth
Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the process. So, researchers ...
Phys.org / Exceptionally well-preserved ant in Goethe's amber examined
Even some 200 years after his death, Johann Wolfgang von Goethe's scientific curiosity continues to yield new insights. This has now been demonstrated by biologists at Friedrich Schiller University Jena while closely examining ...
Medical Xpress / High blood pressure at birth tied to hypertension risk in childhood
High blood pressure at birth may be an early warning sign, setting the stage for cardiovascular disease later in life. A longitudinal study, the ENVIRONAGE birth cohort, set out to understand whether blood pressure (BP) levels ...
Phys.org / Mighty microscopic fibers are the key to cell division and life itself
Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around it called a spindle. The spindle extends its many fibers from the chromosomes ...
Medical Xpress / Deep-learning algorithms enhance mutation detection in cancer and RNA sequencing
Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have developed two innovative deep-learning algorithms, ClairS-TO and Clair3-RNA, that significantly advance genetic mutation detection in cancer ...
Phys.org / Superconducting nanowire memory array achieves significantly lower error rate
Quantum computers, systems that process information leveraging quantum mechanical effects, will require faster and energy-efficient memory components, which will allow them to perform well on complex tasks. Superconducting ...
Phys.org / Swimming in a shared medium makes particles synchronize without touching
Several years ago, scientists discovered that a single microscopic particle could rock back and forth on its own under a steady electric field. The result was curious, but lonely. Now, Northwestern University engineers have ...
Phys.org / Scientists recover the oldest wooden tools from a site in Greece
Two artifacts found at a lake shore in Greece are the oldest wooden tools to be uncovered so far and date back 430,000 years.
Tech Xplore / Origami-inspired ring lets users 'feel' virtual worlds
Virtual reality (VR) and augmented reality (AR) are technologies that allow users to immerse themselves in digital worlds or enhance their surroundings with computer-generated filters or images, respectively. Both these technologies ...
