Biosensors mimic human olfactory system to discriminate between very similar odors
The human olfactory system discriminates between thousands of odors by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different intensities, and the same odorant can activate more th.....»»
Miniature sensor that detects toxic gas shows promising results in the lab
A team of scientists at UNSW Sydney have developed a highly sensitive miniature sensor that is able to detect low levels of the toxic gas nitrogen dioxide (NO2). The tiny, flexible sensor can detect the harmful gas in real-time without requiring an e.....»»

Prototype sunscreen uses TiO₂ nanoparticles to cool skin while blocking UV rays
Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn't cool people off. However, a new formula, described in Nano Letters, protects against both UV light and heat from the sun using radiative cooling......»»
A new way of thinking about skyrmion motion could lead to more robust electronics
The future storage and processing of data stand to benefit greatly from tiny magnetic whirlpools known as skyrmions, which are robust against noise and may be useful in lower power consumption devices. The development of skyrmion-based technologies h.....»»
Astronomers detect new 1.9-second pulsar using FAST
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers have discovered a new pulsar with a spin period of about two seconds. The newly detected pulsar, designated PSR J1922+37, was found in the direction of open.....»»
New strategies enhance stability of metal nanoparticles in green hydrogen production
Efficient and durable low-cost catalysts are essential for green hydrogen production and related chemical fuel production, both vital technologies for the transition to renewable energy. Research in this field increasingly focuses on metal exsolution.....»»
Near-extinct Caribbean reptile makes epic comeback
The Sombrero ground lizard, endemic to a tiny Caribbean island near Anguilla, is a critically endangered reptile. In 2018, it was estimated that fewer than 100 individuals of the species were left in the wild—it was on the very brink of extinction......»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Where"s my qubit? Scientists develop technique to detect atom loss
Quiet quitting isn't just for burned out employees. Atoms carrying information inside quantum computers, known as qubits, sometimes vanish silently from their posts. This problematic phenomenon, called atom loss, corrupts data and spoils calculations.....»»

Hyperspectral imaging lidar system achieves remote plastic identification
Researchers have developed a new hyperspectral Raman imaging lidar system that can remotely detect and identify various types of plastics. This technology could help address the critical issue of plastic pollution in the ocean by providing better too.....»»
Unlocking the brain: Peptide-guided nanoparticles deliver mRNA to neurons
Penn Engineers have modified lipid nanoparticles (LNPs)—the revolutionary technology behind the COVID-19 mRNA vaccines—to not only cross the blood-brain barrier (BBB) but also to target specific types of cells, including neurons. This breakthroug.....»»
Stem cell transplants could save the world"s corals, say researchers
Climate change is bleaching and killing off vast amounts of the world's coral due to rising sea temperatures. Dr. Benyamin Rosental of Ben-Gurion University of the Negev and his colleagues have proposed an out of the box potential solution: transplan.....»»
Detailed bedbug genome analysis may improve pesticides
Bedbugs. Just mentioning the tiny, biting insects that live on human blood and infest mattresses, couches, and bedding strikes fear into most people. In addition to the anxiety, itching, and rashes an outbreak can cause, bedbugs can be difficult to i.....»»
Scientists learn how to make nanotubes that point in one direction
Researchers from Tokyo Metropolitan University have made tungsten disulfide nanotubes which point in the same direction when formed, for the first time. They used a sapphire surface under carefully controlled conditions to form arrayed tungsten disul.....»»
