Published Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions


Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Published First silicon integrated ECRAM for a practical AI accelerator


The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.
Published JWST confirms giant planet atmospheres vary widely


Astronomers have found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend.
Published Temperature of a rocky exoplanet measured


An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.
Published AI 'brain' created from core materials for OLED TVs


A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published Artificial intelligence discovers secret equation for 'weighing' galaxy clusters


Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had. The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists have reported.
Published New in-home AI tool monitors the health of elderly residents


Engineers are harnessing artificial intelligence (AI) and wireless technology to unobtrusively monitor elderly people in their living spaces and provide early detection of emerging health problems.
Published AI finds the first stars were not alone


Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
Published Optical switching at record speeds opens door for ultrafast, light-based electronics and computers


Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. Physicists hope to pave the way for that reality.
Published Surprisingly simple explanation for the alien comet 'Oumuamua's weird orbit


When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar space, cosmic rays converted water to hydrogen in the comet's outer layers. Nearing the sun, outgassed hydrogen gave the tiny comet a kick.
Published Neutrinos made by a particle collider detected


Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a key role in the process that makes stars burn.
Published Galaxy changes classification as jet changes direction


A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.
Published Scientists find a common thread linking subatomic color glass condensate and massive black holes


Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.
Published Researchers create breakthrough spintronics manufacturing process that could revolutionize the electronics industry


Researchers have developed a breakthrough process for making spintronic devices that has the potential to create semiconductors chips with unmatched energy efficiency and storage for use in computers, smartphones, and many other electronics.
Published Mind-control robots a reality?


Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published Superconducting amplifiers offer high performance with lower power consumption


Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and successfully demonstrated a high-performance cooled amplifier with power consumption three orders of magnitude lower than that of conventional cooled semiconductor amplifiers. This result is expected to contribute to the realization of large-scale multi-element radio cameras and error-tolerant quantum computers, both of which require a large number of low-noise microwave amplifiers.
Published 3D-printed revolving devices can sense how they are moving


Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.
Published Qubits put new spin on magnetism: Boosting applications of quantum computers


Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
Published 'Terminator zones' on distant planets could harbor life


In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.
Published Extensive catalog of exploding stars


The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data is publicly available via the Young Supernova Experiment (YSE).
