For the first time in history, scientists have measured radium’s bonding interactions with oxygen atoms in an organic molecule. Scientists have not measured this bonding before because radium-226 is available only in small amounts and it is highly radioactive (radium is one million times more radioactive than the same mass of uranium), making it challenging to work with.

The gene-editing technique employs prime editors along with advanced enzymes known as recombinases. This method has the potential to lead to universal gene therapies that are effective for conditions like cystic fibrosis.

Researchers at the Broad Institute of MIT and Harvard have enhanced a gene-editing technology that can now efficiently insert or replace entire genes in human cell genomes, potentially making it suitable for therapeutic uses.

The advance, from the lab of Broad core institute member David Liu, could one day help researchers develop a single gene therapy for diseases such as cystic fibrosis that are caused by one of hundreds or thousands of different mutations in a gene. Using this new approach, they would insert a healthy copy of the gene at its native location in the genome, rather than having to create a different gene therapy to correct each mutation using other gene-editing approaches that make smaller edits.

Scientists have advanced quantum teleportation by mitigating noise interference through a novel method involving hybrid entanglement, achieving close to 90% fidelity in teleporting quantum states, which could significantly enhance secure quantum communication.

A research team led by Academician Guangcan Guo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), in collaboration with the research team at the University of Turku, Finland, successfully overcame environmental noise to achieve high-fidelity quantum teleportation by utilizing multipartite hybrid entanglement. Their findings were published recently in the journal Science Advances.

New observations spotlight the volatile processes that shape star systems like our own, offering a unique glimpse into the primordial stages of planetary formation.

Astronomers have captured a snapshot of a giant asteroid collision in Beta Pictoris, revealing insights into early planetary formation. The study, using data from the James Webb and Spitzer Space Telescopes, tracked dust changes around the star. The findings suggest a massive collision 20 years ago, altering our understanding of this young star system’s development.

Researchers have created a photonic chip capable of processing images at nanosecond speeds, significantly faster than current methods. This chip enhances edge intelligence by integrating AI analysis directly into optical processing, potentially transforming applications such as autonomous driving.

Researchers have demonstrated a new intelligent photonic sensing-computing chip that can process, transmit and reconstruct images of a scene within nanoseconds. This advance opens the door to extremely high-speed image processing that could benefit edge intelligence for machine vision applications such as autonomous driving, industrial inspection and robotic vision.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., issued a broad agency announcement (HR001124S0029) for the Artificial Intelligence Quantified (AIQ) project.

AIQ seeks to find ways of assessing and understanding the capabilities of AI to enable mathematical guarantees on performance. Successful use of military AI requires ensuring safe and responsible operation of autonomous and semi-autonomous technologies.

LAFAYETTE, Colo. - The U.S. National Aeronautics and Space Administration (NASA) has selected RTX’s small satellite manufacturer and mission services provider Blue Canyon Technologies in Lafayette, Colo., to build two 12U CubeSat buses for NASA’s PolSIR mission.

The PolSIR mission will study ice clouds that form at high altitudes throughout tropical and sub-tropical regions. In addition to designing and manufacturing the bus platforms, Blue Canyon will also provide mission operations services.

The PolSIR instrument –Polarized Submillimeter Ice-cloud Radiometer– will observe the full diurnal cycle of high-altitude ice clouds to improve climate forecasts and provide climate models with important insights into how Earth’s atmosphere will change in the future.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., has issued a solicitation (DARPA-PA-23–03-11) for the Defense Applications of Innovative Remote Sensing (DAIRS) project.

Primary emphasis will be in the high frequency (HF) band nominally at 4 to 15 MHz. Key applications in this frequency band are SWOTHR for aircraft, ship, and boat tracking, oceanographic SWOTHR, and sounding for ionospheric characterization.

Lightweight fighter aircraft with no pilots could support conventional military missions while being easier to launch and recover.
