Activated carbon is used in kitchen fans to eliminate food odours. A new dissertation from the University of Gothenburg shows that activated carbon could also eliminate the smell of urine from diapers. Experiments with the odour molecule p-cresol show that activated carbon, which largely consists of the carbon variant graphene, can lock in odour instead of it being released to ...

Mosquitoes that spread Zika, dengue and yellow fever are guided toward their victims by a scent from human skin. The exact composition of that scent has not been identified until now. A UC Riverside-led team discovered that the combination of carbon dioxide plus two chemicals, 2-ketoglutaric and lactic acids, elicits a scent that causes a mosquito to locate and land ...

NASA Television will provide live coverage of the upcoming Artemis I cryogenic demonstration test on NASA TV beginning at 7:15 a.m. EDT or 4.30 pm IST on Wednesday, Sept. 21. The demonstration test will allow teams to confirm the repair to a hydrogen leak seen during an early September Artemis I launch attempt, evaluate updated propellant loading procedures, and conduct additional evaluations. The demonstration will ...

One approach to treating cancer is photodynamic therapy using photo-uncaging systems, in which light is used to activate a cancer-fighting agent in situ at the tumor. However, suitable agents must be stable under visible light, have an anti-tumor effect in low-oxygen environments, and have the ability to be activated by low-energy tissue-penetrative red light – a combination of properties that is difficult to ...

InSight, which has hit headlines this week with the realtime recording of sound from the Mars when meteoroids struck Mars’ surface at four places since its landing on the Red Planet in November 2018, is nearing the end of its mission by mid-2023. The first NASA mission to explore Mars’ deep interior, InSight rover landed on Mars surface on Nov. ...

The Mars lander’s seismometer has picked up vibrations from four separate impacts in the past two years, which is the first of its kind to have recorded seismic and acoustic waves from an impact on the Red Planet. NASA’s InSight lander has detected seismic waves from four space rocks that crashed on Mars in 2020 and 2021, detected by the ...

Scientists have created a ‘digital mask’ that will allow facial images to be stored in medical records while preventing potentially sensitive personal biometric information from being extracted and shared. In research published today in Nature Medicine, a team led by scientists from the University of Cambridge and Sun Yat-sen University in Guangzhou, China, used three-dimensional (3D) reconstruction and deep learning algorithms ...

Instead of sitting in a tattoo chair for hours enduring painful punctures, imagine getting tattooed by a skin patch containing microscopic needles. Researchers at the Georgia Institute of Technology have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics. “We’ve miniaturized the needle so that it’s ...

After disconnecting the ground and rocket-side plates on the interface, called a quick disconnect, for the liquid hydrogen fuel feed line, teams have replaced the seals on the Space Launch System rocket’s core stage associated with the liquid hydrogen leak detected during the Artemis I launch attempt Sept. 3.  Both the 8-inch line used to fill and drain liquid hydrogen from the core stage and the ...

Engineers are making progress repairing the area where a liquid hydrogen leak was detected during the Artemis I launch attempt Sept. 3, and NASA is preserving options for the next launch opportunity as early as Friday, Sept. 23.  Technicians constructed a tent-like enclosure around the work area to protect the hardware and teams from weather and other environmental conditions at Launch Pad 39B. They ...

NASA is awarding more than $4 million to institutions across the U.S. to help bring the excitement of authentic NASA experiences to groups of middle and high school students who are traditionally underserved and underrepresented in STEM.

Ovarian cancer is most often found in people of middle-age or older as the Wilmot study showed that the mean age of participants was 56. Of the 183 participants, 42 were found to have ovarian cancer, which is 23 percent. The technology also discovered that 20 other participants had non-ovarian cancers. Ovarian cancer symptoms can be vague, such as gas ...

Nature likes spirals – from the whirlpool of a hurricane, to pinwheel-shaped protoplanetary disks around newborn stars, to the vast realms of spiral galaxies across our universe. Now astronomers are bemused to find young stars that are spiraling into the center of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. The outer ...
