University of Central Florida researchers have developed a nanoparticle-based disinfectant that can continuously kill viruses on a surface for up to seven days—a discovery that could be a powerful weapon against COVID-19 and other emerging pathogenic viruses.
When the humidity in the atmosphere is relatively high, the particles naturally present, also known as aerosol droplets, grow to play a significant role in the chemistry and climate of Earth. These particles are produced from either clean or polluted air, after emissions of gases that nucleate and condense while in the atmosphere. Many times this process is affected by the presence of organic...
Climate change could increase the release of greenhouse gases from insect-driven forest decay, a new study has found.
An Imperial-led team of international researchers has used a special X-ray probe to gain new insights into how electrons behave at the quantum level.
When NASA's Mars 2020 Perseverance rover touched down on the Red Planet, the agency's Deep Space Network (DSN) was there, enabling the mission to send and receive the data that helped make the event possible. When OSIRIS-REx took samples of asteroid Bennu this past year, the DSN played a crucial role, not just in sending the command sequence to the probe, but also in transmitting its stunning...
After 7 days of recovery from a 10-day period of deficient sleep, participants in a small study had recovered their pre-sleep deprivation reaction speed, but had not fully recovered on any other measures of function.
Cartilage cells from the nasal septum can not only help repair cartilage injuries in the knee -- according to researchers, they can also withstand the chronic inflammatory tissue environment in osteoarthritis and even counteract the inflammation.
Researchers have genetically engineered cells that, when implanted in mice, deliver a biologic drug in response to inflammation.

A study examining the body mass index (BMI) of over 14,000 children from birth to age 15 shows those in the Midwest have the highest BMI levels while kids in the West have the lowest, suggesting regional influences may play a role in the development of childhood obesity.
Climate change will significantly alter future patterns of flooding, according to a new study. Although future increases in moderate storms won't necessarily lead to more runoff in many regions, extreme storms will generate more devastating and frequent flooding.
A study found that food insecurity among college students is associated with lower college graduation rates and lower chances of obtaining a bachelor's or advanced degree.
Researchers have engineered a bionic arm for patients with upper-limb amputations that allows wearers to think, behave and function like a person without an amputation, according to new findings. The bionic system combines three important functions - intuitive motor control, touch and grip kinesthesia, the intuitive feeling of opening and closing the hand.
