Phys.org / 'Super-puff' planets lighter than candy floss discovered by international team
An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration ...
Phys.org / Ancient proteins hint at all-female Homo naledi burial site in Rising Star cave system
Scientists have extracted and analyzed the first-ever ancient proteins from the fossils of Homo naledi, revealing a potential all-female burial site. The study, published in the journal Cell, raises the possibility that South ...
Medical Xpress / Top supplements Americans use are shifting from multivitamins to targeted health fixes
Dietary supplements are an excellent way to fill gaps in our nutritional requirements. From vitamins and macronutrients to gut-health probiotics, dietary supplements have helped people address deficiencies. In recent years, ...
Phys.org / Quantum squeezing sidesteps the limits on mechanical transducers
From detecting the ripples of colliding black holes to imaging individual chemical bonds, mechanical transducers have repeatedly transformed our understanding of the universe. So far, however, the sensitivity of these devices ...
Phys.org / Laser experiments push helium to record shock pressures
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's ...
Medical Xpress / Exposure to bright evening light linked to higher risk of age-related eye disease
Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern ...
Phys.org / How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Medical Xpress / AI system detects sudden cardiac death risk, identifying thousands more patients annually
Each year in the U.S., more than 300,000 people die from sudden cardiac arrest, a condition in which the heart's electrical system malfunctions without warning. The medical emergency can kill both high-risk older adults and ...
Medical Xpress / Scientists unlock gut-healing power of fruits and nuts paired with the right gut microbes
University of Louisville researchers have discovered how a naturally occurring microbial compound may help protect the gut and support future treatment strategies for inflammatory bowel disease (IBD).
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Phys.org / Language-based screeners may miss kids who struggle to read due to visual-processing issues
Reading difficulties, like dyslexia, are common and often affect achievement and outcomes during school and later in life. A new study, published in Current Biology, reports that current methods used to test for reading disabilities ...
