Researchers find that, overall, prescribing ADHD medications via telehealth does not alter risk of substance use disorder
2025-06-11
Telehealth patients were not more likely to develop substance use disorder
Researchers found that a small number of people who received initial stimulant prescription via telehealth developed stimulant disorder and emphasize the importance of follow-up care
Telehealth can make health care easier to access for patients with attention-deficit/hyperactivity disorder (ADHD) who need treatment, but experts worry about an increased risk of substance use disorder for patients being prescribed controlled medications such as stimulants for ADHD during these appointments. Mass General Brigham researchers scrutinized this concern with the first-ever study comparing ...
How trace elements are recycled in the deep sea
2025-06-11
The oceans are full of living things, with microscopic algae (phytoplankton) at the base of the marine food chain. These organisms make a living in the same way as land plants, using the sunlight that penetrates the upper 100 meters or so of the ocean as the energy source by which they synthesise organic matter for their cells. Every year, these tiny algae make about as much organic carbon as land plants. Like land plants, they obtain the building blocks of their cells from the surrounding environment – not a soil in this case but the seawater solution they live in.
But unlike the land ecosystem, when these algae die, they fall into the dark ...
Cyborg tadpoles with soft, flexible neural implants
2025-06-11
Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a tadpole embryo’s neural plate, the early-stage, flat structure that folds to become the 3D brain and spinal cord.
The researchers demonstrated that the device could integrate seamlessly into the brain as it develops and record electrical activity from single brain cells with millisecond precision, with no impact on normal tadpole embryo development or behavior.
These so-called cyborg tadpoles offer a glimpse into a future in which profound mysteries of the brain could be illuminated, ...
Have a damaged painting? Restore it in just hours with an AI-generated “mask”
2025-06-11
Art restoration takes steady hands and a discerning eye. For centuries, conservators have restored paintings by identifying areas needing repair, then mixing an exact shade to fill in one area at a time. Often, a painting can have thousands of tiny regions requiring individual attention. Restoring a single painting can take anywhere from a few weeks to over a decade.
In recent years, digital restoration tools have opened a route to creating virtual representations of original, restored works. These tools apply techniques of computer vision, image recognition, and color matching, to generate a “digitally restored” version of a painting relatively quickly.
Still, there has ...
NIST and partners use quantum mechanics to make a factory for random numbers
2025-06-11
Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a password or code is an unguessable string of numbers, it’s harder to crack. Many of our cryptographic systems today use random number generators to produce secure keys.
But how do you know that a random number is truly random? Classical computer algorithms can only create pseudo-random numbers, and someone with enough knowledge of the algorithm or the system could ...

World’s first non-silicon 2D computer developed
2025-06-11
UNIVERSITY PARK, Pa. — Silicon is king in the semiconductor technology that underpins smartphones, computers, electric vehicles and more, but its crown may be slipping according to a team led by researchers at Penn State. In a world first, they used two-dimensional (2D) materials, which are only an atom thick and retain their properties at that scale, unlike silicon, to develop a computer capable of simple operations.
The development, published today (June 11) in Nature, represents a major leap toward the realization of thinner, faster and more energy-efficient electronics, the researchers said. They created a complementary metal-oxide semiconductor ...

Paleontologists from the University of Calgary identify closest-known ancestor to Tyrannosaurs
2025-06-11
Paleontologists have identified a new species of dinosaur, Khankhuuluu, which is being described as the closest-known ancestor to the giant Tyrannosaurs.
The finding by an international team of researchers – led by Jared Voris and Dr. Darla Zelenitsky in the Faculty of Science at the University of Calgary – is published in the journal Nature.
Voris, first author and a PhD candidate in the Department of Earth, Energy, and Environment, says the new species of Tyrannosaur would have lived 86 million years ago and was a medium-sized, fleet-footed predator that evolved after the extinction of other large predatory dinosaurs.
Khankhuuluu was ...

2025-06-11
(Sacramento, Calif.) — Researchers at the University of California, Davis, have developed an investigational brain-computer interface that holds promise for restoring the voices of people who have lost the ability to speak due to neurological conditions.
In a new study published in the scientific journal Nature, the researchers demonstrate how this new technology can instantaneously translate brain activity into voice as a person tries to speak — effectively creating a digital vocal tract.
The system allowed the study participant, who has amyotrophic lateral sclerosis (ALS), to “speak” through a computer ...
Feedback for surgeons curbs excess opioid prescriptions scripts
2025-06-11
PHILADELPHIA— Tailored feedback to surgeons dramatically cuts excessive opioid prescriptions for common surgeries, aligning them with evidence-based guidelines without affecting patient pain control. This approach offers a promising strategy to combat the opioid crisis by aligning prescribing practices with evidence-based guidelines, addressing the critical issue of overprescribing, where excessive opioid prescriptions can lead to harmful side effects and can lead to dependence in some patients or diversion of unused pills. The findings, by researchers in the Perelman School of Medicine at the University of Pennsylvania, were published ...

Accelerated molecular transportation in the brain extracellular space with 755-nm light attenuates post-stroke cognitive impairment in rats
2025-06-11
Ischemic stroke exacts a heavy toll in death and disability worldwide. After ischemic stroke, the accumulation of pathobiomolecules in the brain extracellular space (ECS) will exacerbate neurological damage and cognitive impairment. “PBM has been demonstrated to improve cognitive function in Alzheimer’s disease mouse models by accelerating molecular transportation in the brain ECS. This suggests that PBM may have a potential role in the accumulation of pathobiomolecules in the brain ECS following ischemic stroke.” said ...

Green seaweed replaces seagrass, but slugs pose new threats
2025-06-11
Seagrasses are critical to coastal ecosystems – offering habitat, stabilizing the seafloor and buffering wave energy – but globally they’re increasingly under threat. Beginning in 2011, a series of intense algal blooms – fueled by pollution and nutrient overload – wiped out vast stretches of vital seagrass beds in Florida’s Indian River Lagoon (IRL).
In the wake of this collapse, the fast-growing green seaweed Caulerpa prolifera has spread across areas once dominated by native seagrass species like Halodule wrightii, filling in the ...
Ultrasound scanning end-effector with adjustable constant contact force
2025-06-11
Recent advances in robotic ultrasound systems have shown promise for improving diagnostic imaging consistency. However, maintaining stable contact force across dynamic physiological changes (e.g., breathing, tremors) without continuous sensor recalibration remains a critical hurdle. "By integrating a hybrid active-passive force control mechanism, our method decouples force regulation from real-time feedback dependencies while ensuring adaptability across patients," stated corresponding author Qingsong Xu, a professor at the University of Macau. The tripartite system combines (a) a passive constant-force mechanism (positive/negative stiffness ...
Pasteurizing fruit smoothies could improve digestion of beneficial polyphenols
2025-06-11
Drinking a smoothie is a popular way to consume fruits and vegetables, many of which are rich in micronutrients called polyphenols. If this beverage is purchased at a store, it’s likely been pasteurized with heat or pressure to prevent harmful bacteria growth and extend shelf-life. Now, a preliminary study in ACS’ Journal of Agricultural and Food Chemistry reports that processing smoothies with high heat could also make polyphenols easier for the gut microbiome to absorb.
Fruits and vegetables are key to a healthful human diet, ...
Methanol poisoning could be easily detected with a ‘breathalyzer’ sensor
2025-06-11
Breathalyzers are a frequently used tool to measure the amount of ethanol in someone’s breath, which relates to their blood alcohol content. However, alcoholic beverages contaminated by methanol (sometimes called wood alcohol) are hard to identify and toxic if ingested. Researchers reporting in ACS Sensors have developed a prototype sensor that quickly and easily detects small amounts of methanol in breath — a step toward developing a “methanol breathalyzer” to efficiently diagnose poisonings.
Methanol and ethanol, despite being structurally similar, have vastly different effects on the body when ingested. Ethanol gives ...
Green light activates this antibiotic only where it’s needed
2025-06-11
To treat bacterial infections, medical professionals prescribe antibiotics. But not all active medicine gets used up by the body. Some of it ends up in wastewater, where antimicrobial-resistant bacteria can develop. Now, to make a more efficient antibiotic treatment, researchers reporting in ACS Central Science modified penicillin, so that it’s activated only by green light. In early tests, the approach precisely controlled bacterial growth and improved survival outcomes for infected insects.
“Controlling drug activity with light will allow precise and safe treatment of localized infections,” says Wiktor Szymanski, a corresponding author of the study. “Moreover, ...
Eavesdropping on laptop, smart speaker microphones demonstrated in new security attack
2025-06-11
The ghostly woman’s voice pipes through the speakers, covered in radio static but her message intact from beyond — “The birch canoe slid on the smooth planks.”
A secret message from the other side? A spectral insight?
No, something much spookier: Voice recordings captured, secretly, from the radio frequencies emitted by ubiquitous, cheap microphones in laptops and smart speakers. These unintentional signals pass, ghost-like, through walls, only to be captured by simple radio components and translated back to static-filled — but easily intelligible ...
Scientists discover new enzyme families that break down rare bacterial carbohydrates
2025-06-11
The molecules that form the foundation of life on Earth are as diverse as they are complex. Among these, carbohydrates play a vital role as energy sources and in structural functions, such as forming cell walls. One class of carbohydrates, β-1,2-glucans, consists of glucose chains and is found in bacteria. These molecules are involved in various important biological processes, such as bacterial infection and environmental adaptation. Despite their biological significance, β-1,2-glucans are rare, compared to cellulose and laminarin, and structurally complex, making them particularly difficult to ...
