The Sharp Panda cyber-espionage hacking group is targeting high-profile government entities in Vietnam, Thailand, and Indonesia with a new version of the ‘Soul’ malware framework.

The particular malware was previously seen in espionage campaigns targeting critical Southeast Asian organizations, attributed to various Chinese APTs.

Check Point identified a new campaign using the malware that started in late 2022 and continues through 2023, employing spear-phishing attacks for initial compromise.

The FBI is investigating a data breach affecting U.S. House of Representatives members and staff after their account and sensitive personal information was stolen from DC Health Link’s servers.

DC Health Link is the organization that administers the health care plans of U.S. House members, their staff, and their families.

Impacted individuals were notified today of the breach in an email from Catherine L. Szpindor, the U.S. House Chief Administrative Officer, as first reported by DailyCaller.

Using the Atacama Large Millimeter/submillimeter Array (ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA) is the largest ground-based facility for observations in the millimeter/submillimeter regime in the world. ALMA comprises 66 high-precision dish antennas of measuring either 12 meters across or 7 meters across and spread over distances of up to 16 kilometers. It is an international partnership between Europe, the United States, Japan, and the Republic of Chile.

Graphene is a strange material. Understanding its properties is both a fundamental question of science and a promising avenue for new technologies. A team of researchers from the Institute of Science and Technology Austria (ISTA) and the Weizmann Institute of Science has studied what happens when they layer four sheets of it on top of each other and how this can lead to new forms of exotic superconductivity.

Imagine a sheet of material just one layer of atoms thick—less than a millionth of a millimeter. While this may sound fantastical, such a material exists: it is called graphene.

Graphene is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes of carbon, including graphite, charcoal, carbon nanotubes, and fullerenes. In proportion to its thickness, it is about 100 times stronger than the strongest steel.

Studying the relationship between the arrangement of water molecules incorporated into layered materials like clays and the arrangement of ions within these materials has been a difficult experiment to conduct.

However, researchers have now succeeded in observing these interactions for the first time by utilizing a technique commonly used for measuring extremely small masses and molecular interactions at the nanoscale.

The nanoscale refers to a length scale that is extremely small, typically on the order of nanometers (nm), which is one billionth of a meter. At this scale, materials and systems exhibit unique properties and behaviors that are different from those observed at larger length scales. The prefix “nano-” is derived from the Greek word “nanos,” which means “dwarf” or “very small.” Nanoscale phenomena are relevant to many fields, including materials science, chemistry, biology, and physics.

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three dimensions within surrounding tissue.

New findings from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) make it possible for the first time to monitor the functional development and maturation of cardiomyocytes—the cells responsible for regulating the heartbeat through synchronized electrical signals —on the single-cell level using tissue-embedded nanoelectronic devices. The devices—which are flexible, stretchable, and can seamlessly integrate with living cells to create “cyborgs”—are reported in a Science Advances paper.

“These mesh-like nanoelectronics, designed to stretch and move with growing tissue, can continuously capture long-term activity within individual stem-cell derived cardiomyocytes of interest,” says Jia Liu, co-senior author on the paper, who is an assistant professor of bioengineering at SEAS, where he leads a lab dedicated to bioelectronics.

Australian scientists have discovered an enzyme that converts air into energy. The finding, published today in the journal Nature, reveals that this enzyme uses the low amounts of the hydrogen in the atmosphere to create an electrical current. This finding opens the way to create devices that literally make energy from thin air.

The research team, led by Dr. Rhys Grinter, Ph.D. student Ashleigh Kropp, and Professor Chris Greening from the Monash University Biomedicine Discovery Institute in Melbourne, Australia, produced and analyzed a hydrogen-consuming enzyme from a common soil bacterium.

Recent work by the team has shown that many bacteria use hydrogen from the atmosphere as an energy source in nutrient-poor environments. “We’ve known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean” Professor Greening said. “But we didn’t know how they did this, until now.”

Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water being inherited into a protoplanetary disk without significant changes to its composition. These results further suggest that the water in our solar system formed billions of years before the sun. The new observations are published today in Nature.

V883 Orionis is a protostar located roughly 1,305 light-years from Earth in the constellation Orion. The new observations of this protostar have helped scientists to find a probable link between the water in the interstellar medium and the water in our solar system by confirming they have similar composition.

Their popularity makes celebrities easy to spot. Strangers, however, can also get mistaken for celebrities, resulting in cases of false “celebrity sightings.” In attempting to explain the contradiction, a University of California, Riverside, study reports that celebrity faces are remembered more precisely but less accurately.

Precision, in this context, refers to how memories for a particular face resemble each other over repeated memory retrievals, which can be likened to the clustering of arrows on a target in archery. Accuracy measures how remembered faces resemble newly encountered faces—or the deviation from the target in archery.

“What our findings say is that people might accept errors by misidentifying someone as a celebrity in the interest of securing a ‘celebrity sighting,’” said Weiwei Zhang, an associate professor of psychology, who led the study that appears in the journal Psychonomic Bulletin & Review. “Our study explains why people are good and bad at spotting celebrities and highlights the importance of assessing both memory imprecision and bias in memory performance.”
