Using sophisticated simulations of the whole of the Local Group of galaxies, including the Milky Way, the Andromeda galaxy and their respective satellite galaxies, researchers have shown that the satellites not only can retain their gas but can also experience many new episodes of star formation just after passing close to the pericenter of their parent galaxy.

Engineers have developed an integrated circuit that can carry out complicated artificial-intelligence operations like face, voice and gesture recognition and cardiac monitoring. Powered by either a tiny battery or a solar panel, it processes data at the edge and can be configured for use in just about any type of application.

Researchers have moved closer toward this goal by developing a nanopore sequencing platform that, for the first time, can detect the presence of nucleobases, the building blocks of DNA and RNA.

Careful criminals usually clean a scene, wiping away visible blood and fingerprints. However, prints made with trace amounts of blood, invisible to the naked eye, could remain. Dyes can detect these hidden prints, but the dyes don't work well on certain surfaces. Now, researchers have developed a fluorescent polymer that binds to blood in a fingerprint -- without damaging any DNA also on the surface -- to create high-contrast images.

Scientists reported new research results today suggesting that artificial objects in orbit around the Earth are brightening night skies on our planet significantly more than previously understood.

Since the introduction of plastic (polymer) banknotes in 2016, the number of counterfeit notes on the streets has increased, however, researchers have developed a novel technique called Polymer Substrate Fingerprinting, which identifies every banknote's fingerprint which is unique and unclonable.

Analysis of observations made by satellites in 2014 has revealed a long-lasting 'space hurricane' -- a swirling mass of plasma several hundred kilometers above the North Pole, raining electrons instead of water.

The remarkable genetic scissors called CRISPR/Cas9, the discovery that won the 2020 Nobel Prize in Chemistry, sometimes cut in places that they are not designed to target.

New research has found that optical coherence tomography (OCT) imaging technology can be utilized to distinguish between legitimate and counterfeit travel documents.

Researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals -- everything from illicit drugs to pollution -- as quickly as a breathalyzer identifies alcohol.

A single strand of hair in a crime scene contains many clues that can help identify a perpetrator. In a recent study, scientists have combined two modern techniques, called surface-enhanced Raman spectroscopy and X-ray fluorescence, to distinguish between different colors in individual hair strands. Both these techniques are almost non-destructive and can be conducted with portable devices, making this a promising way to get supportive evidence in forensic investigations.

Observations confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these findings may help alleviate such conditions.

Human fingerprints have a self-regulating moisture mechanism that not only helps us to avoid dropping our smartphone, but could help scientists to develop better prosthetic limbs, robotic equipment and virtual reality environments, a new study reveals.

Forensic science experts are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport.

Liquids aren't as well behaved in space as they are on Earth. Inside a spacecraft, microgravity allows liquids to freely slosh and float about. This behavior has made fuel quantity in satellites difficult to pin down, but a new 3D-imaging fuel gauge could offer an ideal solution.
