A pair of microspheres can convert microwave signals over a wide frequency range into optical signals, which will be essential for future quantum technologies.

Future quantum communication systems will likely use microwaves to transfer information into and out of storage and processing devices but will use lasers to carry information from point to point within an extended network. Now researchers have demonstrated an improved method for converting microwaves to visible light signals by exploiting the way that electromagnetic waves can set up vibrations within microspheres [1]. Two microspheres in contact—one sensitive to microwaves and the other sensitive to optical signals—serve as the core of the converter. The work should give researchers a wider range of technological options as they develop advanced communications and computing networks.

Researchers are pursuing a variety of ways to store quantum information, or “qubits,” in microscopic, typically superconducting, structures. One common feature of such technologies is that reading or writing information relies on interactions with microwaves rather than on higher-frequency visible or infrared light from lasers. But lasers offer the best way to move information around, so extended networks of such devices will need ways to convert signals from one form to the other.

A new therapy that makes the immune system kill bone marrow cancer cells was successful in as many as 73% of patients in two clinical trials, according to researchers from The Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai.

The therapy, known as a bispecific antibody, binds to both T cells and multiple and directs the T cells— that can be enlisted to fight off diseases—to kill multiple cells. The researchers described this strategy as “bringing your army right to the enemy.”

The success of the off-the-shelf immunotherapy, called talquetamab, was even seen in patients whose was resistant to all approved multiple myeloma therapies. It uses a different target than other approved therapies: a receptor expressed on the surface of cancer cells known as GPRC5D.

In recent years, engineers have been working to develop increasingly sophisticated and smaller electronic components that could power the devices of the future. This includes thin and stretchable components that could be easily worn on the skin or implanted inside the human body.

Researchers at RIKEN, Nanyang Technological University, National University of Singapore, University of Tokyo, and other institutes in Japan, Singapore and China have recently realized a new, elastic electrical conductor that is 1.3-micrometers thin. This conductor, introduced in a paper published in Nature Electronics, could advance the development of both wearable and implantable sensors.

“Ultrathin electronic devices can form a conformal interface with curved surfaces, are not perceivable by human when wearing, and do not induce strong foreign body rejection (FBR) when implanted in animals,” Zhi Jiang, one of the researchers who carried out the study, told TechXplore.

An analysis of 22 large-scale gene expression datasets pointed to exercise and activity in general as the most effective theoretical treatment for reversing gene expressions typical of Alzheimer’s disease. Fluoxetine, a well-known antidepressant, also showed effect, particularly when combined with exercise. Curcumin showed positive effects as well. The study was published in Scientific Reports.

Alzheimer’s disease is a complex neurodegenerative disorder that affects multiple brain regions. It is the most common disease that causes dementia and is very difficult to treat. In the course of the disease, abnormal collections of proteins called tau accumulate inside neurons.

Another type of protein clumps together to form so-called amyloid plaques that collect between neurons and disrupt cell functions. These and other changes harm the functioning of the brain across different regions and lead to dysfunction and death of brain cells.

2022 the Colorado State Fair’s annual art competition gave out prizes in all the usual art categories.

“Thé tre D’opéra Spatial,” took home the blue ribbon in the fair’s contest for emerging digital artists — making it one of the first A.I.-generated pieces to win such a prize.

We still don’t have a clear picture of the Sun’s physics — but the Solar Ring could change that.

To solve this a team of astronomers proposes the Solar Ring. The Solar Ring is a fleet of three spacecraft that will all orbit around the Sun. They will be separated from each other by 120 degrees and be fitted with identical instruments. This way their overlapping fields of view will make it impossible for us to miss anything happening on the surface.

Among the many kinds of observations that the astronomers behind the Solar Ring hope to perform, one involves a technique called reverberation mapping. By carefully mapping the velocity of gas on the surface of the Sun, they can measure vibrations and pulsations. These kinds of “sunquakes” give astronomers rich information about what is happening within deeper layers, much like how earthquakes tell us about the core and mantle of the Earth.

The Solar Ring will also be able to catch the beginnings of a solar flare or an eruption event no matter where it happens on the Sun, providing even more early warning for space weather. These kinds of plasma storms can disrupt satellites and even affect electrical systems on the Earth’s surface, so the more warning, the better.

A s of 1 February 2021, there are about 280 million domestic LPG (liquified petroleum gas) consumers in India, according to Union Minister Dharmendra Pradhan. By March 2022, the Government of India expects that there will be over 300 million consumers. Indian Oil, the country’s largest fuel refiner, claims that it will import 50% more cooking gas to ensure the supply of LPG remains uninterrupted for its bottling plants.

It’s imperative to find heating solutions that are more efficient.

Moreover, the Government of India has been encouraging wider adoption of LPG to replace coal and firewood to improve air quality as well. But according to researchers at IIT-Guwahati, the thermal efficiencies of conventional domestic LPG cooking stoves available in the market are low (60–68%), and emissions are high (CO: 220–550 ppm, NOx: 5–25 ppm).
