Japan-based Kirin Holdings has showcased its new electric spoon at this year’s Consumer Electronics Show (CES 2025) in Las Vegas.
What makes it different from any other ordinary spoon in the market is that it can make the food seem saltier, and by that, it also means tastier.
As per Kirin, the device uses electricity to raise the saltiness and umami in low-sodium foods.
Researchers have developed a new method for quickly detecting and identifying very low concentrations of gases. The new approach, called coherently controlled quartz-enhanced photoacoustic spectroscopy, could form the basis for highly sensitive real-time sensors for applications such as environmental monitoring, breath analysis and chemical process control.
“Most gases are present in small amounts, so detecting gases at low concentrations is important in a wide variety of industries and applications,” said research team leader Simon Angstenberger from the University of Stuttgart in Germany. “Unlike other trace gas detection methods that rely on photoacoustics, ours is not limited to specific gases and does not require prior knowledge of the gas that might be present.”
In Optica, the researchers report the acquisition of a complete methane spectrum spanning 3,050 to 3,450 nanometers in just three seconds, a feat that would typically take around 30 minutes.
When unable to smell prey, female Aedes aegypti mosquitoes turn to—and upregulate—heat sensors in their legs, new Science Advances research finds.

Birds are the undisputed champions of epic travel, but they are not the only long-haul fliers. A handful of bats are known to travel thousands of kilometers in continental migrations across North America, Europe, and Africa. The behavior is rare and difficult to observe, which is why long-distance bat migration has remained an enigma.
Now, scientists from the Max Planck Institute of Animal Behavior (MPI-AB) have studied 71 common noctule bats on their spring migration across the European continent, providing a leap in understanding this mysterious behavior. Ultra-lightweight, intelligent sensors attached to bats uncovered a strategy used by the tiny mammals for travel: they surf the warm fronts of storms to fly further with less energy. The study is published in Science.
“The sensor data is amazing,” says first author Edward Hurme, a postdoctoral researcher at MPI-AB and the Cluster of Excellence Collective Behavior at the University of Konstanz. “We don’t just see the path that bats took, we also see what they experienced in the environment as they migrated. It’s this context that gives us insight into the crucial decisions that bats made during their costly and dangerous journeys.”
Prof Zhang Zhiyong’s team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded specific detectivity above 1014 Jones at 1,300 nm, making it capable of starlight detection. Their research was recently published in the journal Advanced Materials, titled “Opto-Electrical Decoupled Phototransistor for Starlight Detection.”
Highly sensitive shortwave infrared (SWIR) detectors are essential for detecting weak radiation (typically below 10−8 W·Sr−1 ·cm−2 ·µm−1) with high-end passive image sensors. However, mainstream SWIR detection based on epitaxial photodiodes cannot effectively detect ultraweak infrared radiation due to the lack of inherent gain.
Filling this gap, researchers at the Peking University School of Electronics and collaborators have presented a heterojunction-gated field-effect transistor (HGFET) that achieves ultra-high photogain and exceptionally low noise in the short-wavelength infrared (SWIR) region, benefiting from a design that incorporates a comprehensive opto-electric decoupling mechanism.

Apple could bring Samsung into its camera sensor supply chain, with a new rumor claiming that it is developing a new 3-layer stacked sensor.
NSF NOIRLab rings in the New Year with a glittering galaxyscape captured with the Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab. This ultra-deep view of the Antlia Cluster reveals a spectacular array of galaxy types among the hundreds that make up its population.
Galaxy clusters are some of the largest known structures in the known universe. Current models suggest that these massive structures form as clumps of dark matter and the galaxies that form within them are pulled together by gravity to form groups of dozens of galaxies, which in turn merge to form clusters of hundreds, even thousands.
One such group is the Antlia Cluster (Abell S636), located around 130 million light-years from Earth in the direction of the constellation Antlia (the Air Pump).
