Smart devices should space out vibrations to maximize user alert benefits

A research team found that haptic feedback (such as vibration feedback) causes distraction, but this loss of focus lasts only for about one second. The findings can help designers improve the usability of notification features in devices. Reported by Science Daily

Molecular circuitry: International team breaks one-diode-one resistor electronics

An international team has cracked a challenge that could herald a new era of ultra-high-density computing. For years engineers and scientists around the world have been trying to make smaller and faster electronics. Many teams are working on combining the diode and resistor into a single ...

Blood markers predict Humboldt penguin nest type, reproductive success

Researchers looked at metabolic markers in the blood of 30 Humboldt penguins nesting in the Punta San Juan Marine Protected Area in Peru. The scientists discovered metabolic differences between penguins nesting in sheltered burrows and those in more exposed areas. Nesting success is critical ... Reported by Science Daily

Expression of certain genes may affect vulnerability to post-traumatic stress disorder

A new study suggest that whether certain genes are expressed may play a role in susceptibility to post-traumatic stress disorder (PTSD). Reported by Science Daily

From dark to light in a flash: Smart film lets windows switch autonomously

Researchers have developed a new easy-to-use smart optical film technology that allows smart window devices to autonomously switch between transparent and opaque states in response to the surrounding light conditions. Reported by Science Daily

Gene discovery in fruit flies 'opens new doors' for hearing loss cure in elderly

Scientists have discovered sets of regulatory genes, which are responsible for maintaining healthy hearing. The finding, made in fruit flies, could potentially lead to treatments for age-related hearing loss (ARHL) in humans. Reported by Science Daily

Exotic nanotubes move in less-mysterious ways

Researchers capture the first video of boron nitride nanotubes in motion to prove their potential for materials and medical applications. Reported by Science Daily

'A litmus paper for CO2:' Scientists develop paper-based sensors for carbon dioxide

A new sensor for detecting carbon dioxide can be manufactured on a simple piece of paper, according to physicists. Reported by Science Daily

Citizen scientists spot closest young brown dwarf disk yet

Scientists spot a brown dwarf disk that is the closest young system yet discovered. Reported by Science Daily

Good night? Satellite data uncovers dolphins on the move at nighttime

More than 1,000 bottlenose dolphins live in Florida's Indian River Lagoon year-round. Although extensively studied, what they do at nighttime is still a mystery. Using satellite telemetry, scientists provide the first documentation that these dolphins have a larger range that encompasses more ... Reported by Science Daily

Gene found that causes eyes to wither in cavefish

In a new study led by University of Maryland researchers, scientists discovered a gene that prevents blood flow to blind cavefish eyes during development. It is the same gene responsible for homocystinuria in humans. Reported by Science Daily

U.S. opens national security probe into vanadium imports

The U.S. Commerce Department said on Tuesday it was opening an investigation into whether imports of vanadium, a metal used in aerospace, defense and energy applications, impair U.S. national security. Reported by Reuters

Large simulation finds new origin of supermassive black holes

Computer simulations conducted by astrophysicists have revealed a new theory for the origin of supermassive black holes. In this theory, the precursors of supermassive black holes grow by swallowing up not only interstellar gas, but also smaller stars as well. This helps to explain the large ...

Tiger snakes tell more about local wetlands' pollution levels

Tiger snakes living in Perth's urban wetlands are accumulating toxic heavy metals in their livers, suggesting that their habitats -- critical, local ecosystems -- are contaminated and the species may be suffering as a result. Reported by Science Daily

A better model for neutrophil-related diseases

Neutrophils are critical immune cells for antimicrobial defense, but they can exacerbate a number of diseases, perhaps including COVID-19. The traditional approaches to study neutrophils in animal models are limited in specificity and effectiveness. Scientists have now identified the problem ... Reported by Science Daily

Latest climate models show more intense droughts to come

An analysis of new climate model projections shows southwestern Australia and parts of southern Australia will see longer and more intense droughts due to a lack of rainfall caused by climate change. But Australia is not alone. Across the globe, several important agricultural and forested ... Reported by Science Daily

Bees grooming each other can boost colony immunity

Honeybees that specialise in grooming their nestmates (allogroomers) to ward off pests play a central role in the colony, finds a new UCL and University of Florence study published in Scientific Reports. Reported by Science Daily

Scientists Question Medical Data Used in Second Coronavirus Study

Medical records from a little-known company were used in two studies published in major journals. The New England Journal of Medicine has asked to see the data. Reported by NYTimes

Pre-COVID-19 poll of older adults hints at potential impact of pandemic on eating habits

Few shopped for groceries online, and self-rating of healthy eating was higher among those who dined alone or at restaurants least, a new national U.S. poll finds. Reported by Science Daily
