For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that’s massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac fermion, was first theorized 16 years ago, but was only recently spotted inside a crystal of semi-metal material called ZrSiS. The observation of the quasiparticle opens the door to future advances in a range of emerging technologies from batteries to sensors, according to the researchers.

The team, led by scientists at Penn State and Columbia University, recently published their discovery in the journal Physical Review X.

“This was totally unexpected,” said Yinming Shao, assistant professor of physics at Penn State and lead author on the paper. “We weren’t even looking for a semi-Dirac fermion when we started working with this material, but we were seeing signatures we didn’t understand—and it turns out we had made the first observation of these wild quasiparticles that sometimes move like they have mass and sometimes move like they have none.”

We all know that time seems to pass at different speeds in different situations. For example, time appears to go slowly when we travel to unfamiliar places. A week in a foreign country seems much longer than a week at home.

Time also seems to pass slowly when we are bored, or in pain. It seems to speed up when we’re in a state of absorption, such as when we play music or chess, or paint or dance. More generally, most people report time seems to speed up as they get older.

However, these variations in time perception are quite mild. Our experience of time can change in a much more radical way. In my new book, I describe what I call “time expansion experiences” – in which seconds can stretch out into minutes.

Astronomers admit: we were wrong—100 billion habitable earth-like planets in our galaxy alone.

Estimates by astronomers indicate that there could be more than 100 BILLION Earth-like worlds in the Milky Way that could be home to life. Think that’s a big number? According to astronomers, there are roughly 500 billion galaxies in the known universe, which means there are around-1 (5×1022) habitable planets. That’s of course if there’s just ONE universe.

NVIDIA is rumored to ditch TSMC’s 2nm process, and instead turn towards Samsung Foundry, given the high costs associated and the Taiwan giant’s growing influence in controlling prices.

NVIDIA & Other Tech Giants Now Focused On Diversifying 2nm Supply China, Including Partners Other Than TSMC

Well, TSMC’s 2nm superiority might be jeopardized here, as mainstream industry clients are now looking towards alternatives. In a report by Ctee citing South Korean media, NVIDIA and others are already in discussion to move away 2nm orders from the Taiwan giant, and shifting it to the likes of Samsung Foundry, given that the parties involved believe that 2nm costs are way too higher for adoption right now. With TSMC being the sole “credible” supplier, the firm is using this stance to control the prices.

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.

Limitations of Existing Quantum Memory.

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.
