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 / NASA's Juno measures thickness of Europa's ice shell
Data from NASA's Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter's moon Europa. Using the spacecraft's Microwave Radiometer (MWR), mission scientists determined ...
Phys.org / Great white sharks grow a whole new kind of tooth for slicing bone as they age
A great white shark is a masterwork of evolutionary engineering. These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialized for stealth, speed ...
Phys.org / Novel 'XFELO' laser system produces razor-sharp X-ray light
A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the process, much like happens ...
Phys.org / Small-scale farmers produce more of the rich world's food than previously thought
Who grows our food? This seemingly simple question is getting harder to answer in a world where our food crosses borders to get to our plate.
Phys.org / Rare fossils reveal 91 new species that survived ancient mass extinction
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday.
Phys.org / Ancient Spanish trees reveal Mediterranean storms are intensifying
Ancient pine trees growing in the Iberian mountains of eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Now, by reading the annual growth rings preserved in their wood, scientists have ...
Phys.org / Pesticides significantly affect soil life and biodiversity, study finds
Seventy percent of soils in Europe are contaminated with pesticides. A Europe-wide study co-led by researchers of the University of Zurich now shows that their effects on soil life are substantial, as pesticides suppress ...
Phys.org / Surprising green ice on Lake Lipno: Cyanobacteria bloom in mid-winter
An unusual natural phenomenon appeared on Lake Lipno in South Bohemia, the Czech Republic, at the end of 2025. Large amounts of accumulated cyanobacteria in the water caused the ice to turn green. The phenomenon was thoroughly ...
Medical Xpress / Telesurgery matches local robotic urological surgery in first randomized trial
Telesurgery (operating on a patient remotely using a surgical robot via a secure telecommunication link) appears to be as reliable as standard robotic surgery (when the surgeon and patient are in the same room) for two common ...
Medical Xpress / Rethinking ultrasound gel: A natural solid pad for clearer, more comfortable imaging
Ultrasonography is a noninvasive imaging technique used for real-time imaging. This versatile technique is used as a reliable diagnostic tool in various modalities. The conventional liquid gel used in ultrasonography is a ...
Phys.org / How gut bacteria control immune responses
Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led by researchers at Helmholtz Munich, with participation from Ludwig Maximilians University (LMU), ...
