Photons, however, are volatile. Therefore, feasible alternatives are being sought for certain applications, such as quantum memory or quantum repeater schemes. One such alternative is the acoustic domain, where quanta are stored in acoustic or sound waves.

Scientists at the MPL have now indicated a particularly efficient way in which photons can be entangled with : While the two quanta travel along the same photonic structures, the phonons move at a much slower speed. The underlying effect is the optical nonlinear effect known as Brillouin-Mandelstam scattering. It is responsible for coupling quanta at fundamentally different energy scales.

In their study, the scientists showed that the proposed entangling scheme can operate at temperatures in the tens of Kelvin. This is much higher than those required by standard approaches, which often employ expensive equipment such as dilution fridges. The possibility of implementing this concept in optical fibers or photonic integrated chips makes this mechanism of particular interest for use in modern .

A new variant of human mpox has claimed the lives of approximately 5% of people with reported infections in the Democratic Republic of the Congo since 2023, many of them children. Since then, it has spread to several other countries. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on August 14. In addition, a different but rarely fatal mpox variant was responsible for an outbreak that has spread to more than 100 countries since 2022.

There is an urgent need for faster and more cost-effective diagnostic tools to curb the spread of mpox and to prepare for the possibility of a future global pandemic. Researchers from University of California School of Medicine, Boston University, and their colleagues have now developed an optical biosensor that can rapidly detect monkeypox, the that causes mpox. The technology could allow clinicians to diagnose the disease at the point of care rather than wait for .

The team’s study is published in Biosensors and Bioelectronics.

Researchers at New York University have devised a mathematical approach to predict the structures of crystals—a critical step in developing many medicines and electronic devices—in a matter of hours using only a laptop, a process that previously took a supercomputer weeks or months. Their novel framework is published in the journal Nature Communications.

Researchers led by the University of California, Irvine are the first to reveal how two neural circuits located in the brain’s retrosplenial cortex are directly linked to spatial navigation and memory storage. This discovery could lead to more precise medical treatments for Alzheimer’s disease and other cognitive disorders by allowing them to target pathway-specific neural circuits.

The study, published in Molecular Psychiatry, identified two types of RSC pathways, connected to different parts of the brain, each with its own pattern of inputs and functions.

“By demonstrating how specific circuits in the RSC contribute to different aspects of cognition, our findings provide an anatomical foundation for future studies and offer new insights into how we learn and remember the space around us,” said lead and co-corresponding author Xiangmin Xu, UC Irvine Chancellor’s Professor of anatomy and neurobiology and director of the campus’s Center for Neural Circuit Mapping.

Think back to that basic biology class you took in high school. You probably learned about organelles, those little ‘organs’ inside cells that form compartments with individual functions.

For example, mitochondria produce energy, lysosomes recycle waste and the nucleus stores DNA. Although each organelle has a different function, they are similar in that every one is wrapped up in a membrane.

Membrane-bound organelles were the textbook standard of how scientists thought cells were organized until they realized in the mid-2000s that some organelles don’t need to be wrapped in a membrane.

Akash Systems has signed a non-binding preliminary memorandum of terms with the U.S. Department of Commerce for $18.2 million in direct funding and $50 million in federal and state tax credits through the CHIPS Act. Although this isn’t yet a binding contract that will give the company the promised funds, it’s an important first step in the negotiation process for the Oakland-based startup, which shows that both the company and the U.S. government are gradually moving towards a formal agreement. According to Akash Systems (h/t Axios), it will use the funds to ramp up its operations for producing diamond-cooled semiconductors for AI, data centers, space applications, and defense markets.

Diamond-cooling technology goes deeper than just thermal paste with nano-diamond technology. For example, some use synthetic diamonds as the chip substrate, utilizing the material’s thermal conductivity to more efficiently move heat away from the processor. So, let’s look closer at Akash’s solution.
