A groundbreaking step in quantum technology has been achieved with the demonstration of an integrated spin-wave quantum memory, overcoming challenges of photon transmission loss and noise suppression.

Quantum memories play a crucial role in creating large-scale quantum networks by enabling the connection of multiple short-distance entanglements into long-distance entanglements. This approach helps to overcome photon transmission losses effectively. Rare-earth ion-doped crystals are a promising candidate for implementing high-performance quantum memories, and integrated solid-state quantum memories have already been successfully demonstrated using advanced micro-and nano-fabrication techniques.

Summary: New research reveals that certain cells inactivate one parent’s copy of a gene, leading to a bias in gene activity that may explain why some individuals with disease-causing mutations remain symptom-free. This selective gene inactivation, known as monoallelic expression, affects about 1 in 20 genes and varies between cell types.

The study shows that in families with genetic disorders, the active copy of a gene often determines disease severity. These findings challenge traditional genetic paradigms and suggest new approaches to diagnosing and treating inherited diseases.

Did you see the Northern Lights this week? The new year arrived not only with fireworks, but with displays of aurora across the world at much more southerly latitudes than is normal.

Aurora were spotted as far south as Mexico, Colorado, Arizona, Wales in the U.K and France, with spectacular displays in Alaska, Scandinavia and New Zealand, according to SpaceWeather.com.

The display aurora came in the wake of forecasts for northern and Midwest U.S. states after a flurry of solar flares from the sun’s surface in the last few days of 2024, most notably an X-class event on Dec. 29 that hurled two clouds of charged particles in Earth’s direction.

In a shocking turn of events, a surgeon operating on a cancer patient managed to contract the deadly disease in what is believed to be an unprecedented case. The doctor was performing surgery on a 32-year-old German man suffering from a rare type of cancer when he accidentally “transplanted” the disease into himself.

This occurred when cells from the patient’s tumor seeped into a cut on the surgeon’s hand. Despite immediate disinfection and bandaging, the 53-year-old medic noticed a hard lump developing at the base of his middle finger five months later.

A hand specialist identified the lump as a malignant tumor genetically identical to cancer suffered by his former patient. Doctors treating him concluded that he had contracted cancer when his patient’s tumor cells seeped into the cut.

Scientists are exploring 2D materials — sheets just one atom thick — with unique and promising electronic properties.

When two of these sheets are layered at specific angles, they can exhibit remarkable behaviors, such as superconductivity. Antonija Grubišić-Čabo, a materials scientist at the University of Groningen, and her colleagues investigated one such “twisted” material and found that it behaved in ways that defied existing theoretical predictions.

2D Materials and Superconductivity.

In china their resources are getting overwhelmed and it seems to be similar to covid 19. I think it could be another pandemic in weeks globally.

A mysterious virus known as HMPV (human metamnemovirus) is reportedly spreading in China, raising concerns due to its similarities with the COVID-19 outbreak.

It was easy to miss Dr. Robert Gray’s quick movements, tapping the screen of his smartphone at the beginning and end of patient visits on a recent day.

But Gray said those fast finger taps have changed his life. He was tapping an app that records discussions during his appointments and then uses to find the relevant information, summarize it and zap it, within seconds, into each patient’s electronic medical record.

The technology was meticulously documenting each visit so Gray didn’t have to.

Conventional photonic devices exhibit static optical properties that are design-dependent, including the material’s refractive index and geometrical parameters. However, they still possess attractive optical responses for applications and are already exploited in devices across various fields. Hydrogel photonics has emerged as a promising solution in the field of active photonics by providing primarily deformable geometric parameters in response to external stimuli. Over the past few years, various studies have been undertaken to attain stimuli-responsive photonic devices with tunable optical properties. Herein, we focus on the recent advancements in hydrogel-based photonics and micro/nanofabrication techniques for hydrogels. In particular, fabrication techniques for hydrogel photonic devices are categorized into film growth, photolithography (PL), electron-beam lithography (EBL), and nanoimprint lithography (NIL). Furthermore, we provide insights into future directions and prospects for deformable hydrogel photonics, along with their potential practical applications.

Oregon State University researchers have found luminescent nanocrystals with fast light-dark switching capabilities.

“The extraordinary switching and memory capabilities of these nanocrystals may one day become integral to optical computing – a way to rapidly process and store information using light particles, which travel faster than anything in the universe,” said Artiom Skripka, assistant professor in the OSU College of Science.

The race for faster, more efficient computing is on. And now, scientists have taken a significant leap forward with the discovery of a unique type of nanocrystal.

This has the potential to accelerate artificial intelligence and data processing speed, while also enhancing energy efficiency.
