Researchers have engineered ultracold molecular transitions ideally suited for probing beyond-standard-model effects of symmetry violations.
High-temperature cuprate superconductors are a broad class of materials that exhibit some unique characteristics. Due to their distinctive properties, these materials exhibit the highest superconducting temperatures reported to date under ambient pressure.
Researchers at the Chinese Academy of Sciences and other institutes in China recently carried out a study aimed at better understanding the processes underpinning the high superconducting critical temperatures (Tc) observed in trilayer cuprates, a class of materials with three layers based on compounds containing copper. Their paper, published in Nature Physics, unveiled the electronic origin of the high Tc exhibited by these three-layered materials.
“Our group has been trying to understand the high temperature superconductivity mechanism in cuprate superconductors for many years,” Xingjiang Zhou, one of the researchers who carried out the study, told Phys.org.
An interdisciplinary international research team has recently discovered that a massive anomaly deep within the Earth’s interior may be a remnant of the collision about 4.5 billion years ago that formed the moon.
This research offers important new insights not only into Earth’s internal structure but also its long-term evolution and the formation of the inner solar system.
The study, which relied on computational fluid dynamics methods pioneered by Prof. Deng Hongping of the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, was published as a featured cover in Nature on Nov. 2.
In a world filled with endless connections and constant communication, the relationship between loneliness and aloneness is not always clear. Now, University of Arizona researchers have analyzed that relationship—and found that they are two different things that are not closely correlated.
People don’t feel lonely until they spend three-quarters of their time alone, the study found. However, when their alone time goes beyond 75%, it becomes difficult for them to avoid feelings of loneliness.
Published in the Journal of Research in Personality in September, the study also concludes that among older adults, there is a particularly strong association between time spent alone and feeling lonely. The study was led by Alex Danvers, a former postdoctoral associate at UArizona, and Liliane Efinger, a former visiting graduate student.
‘3D Pin’ technique helps researchers form stable bonds between suspended nanocrystals to create robust 3D structures.
Researchers at the National Institutes of Health have developed a way to potentially increase the effectiveness of T cell–based immunotherapy treatments, such as CAR T-cell therapy, against solid tumors. T cells are specialized white blood cells of the immune system that eliminate infected or abnormal cells. In animal studies, the enhanced T-cell therapies were effective against cervical cancer and neuroblastoma, a common solid tumor in children. The findings, by scientists at the National Cancer Institute (NCI), part of NIH, appear in Clinical Cancer Research.
CAR T-cell therapy is a form of cellular immunotherapy that involves engineering T cells in the laboratory so they can specifically target and kill tumors. CAR T-cell therapy has been successful in treating blood cancers, but it hasn’t worked well for solid tumors. To improve the effectiveness of T-cell therapy against solid tumors, researchers at NCI’s Center for Cancer Research engineered T cells (CAR T cells and another form of cellular immunotherapy called TCR T cells) to carry cytokines, which are proteins that can boost T-cell function.
In laboratory studies, CAR and TCR T cells modified to express the cytokines IL-15 and IL-21 on their surface killed far more cancer cells than T cells carrying just one of these cytokines or neither of them. Previous research has found that treating patients with large amounts of cytokines caused severe, potentially fatal, side effects. The new approach aims to deliver this cytokine boost in a much more targeted way.

Transplant is the only option now for liver failure, but it’s not for everyone. One Mayo Clinic M.D./Ph. D. student and her mentor are researching ways to regenerate liver cells as a possible treatment for end-stage liver disease.
“Research provides us with the understanding to develop tools to make big changes in clinical problems like those facing patients with liver failure,” says Nguyen. “I want to be on the forefront of developing medical technologies that provide alternatives. I derive a lot of passion for research through thinking about the future patients I will be treating in the clinic.”
Nguyen is a fifth-year M.D.-Ph. D. student in the Mayo Clinic Alix School of Medicine, who is also completing her Ph.D. in regenerative sciences through the Mayo Clinic Graduate School of Biomedical Sciences.

Astronomers are currently pushing the frontiers of astronomy. At this very moment, observatories like the James Webb Space Telescope (JWST) are visualizing the earliest stars and galaxies in the universe, which formed during a period known as the “Cosmic Dark Ages.” This period was previously inaccessible to telescopes because the universe was permeated by clouds of neutral hydrogen.
As a result, the only light is visible today as relic radiation from the Big Bang—the cosmic microwave background (CMB)—or as the 21 cm spectral line created by the reionization of hydrogen (aka the Hydrogen Line).
Now that the veil of the Dark Ages is being slowly pulled away, scientists are contemplating the next frontier in astronomy and cosmology by observing “primordial gravitational waves” created by the Big Bang. In recent news, it was announced that the National Science Foundation (NSF) had awarded $3.7 million to the University of Chicago, the first part of a grant that could reach up to $21.4 million. The purpose of this grant is to fund the development of next-generation telescopes that will map the CMB and the gravitational waves created in the immediate aftermath of the Big Bang.
That’s a great step.
LOUISVILLE, Colorado—The first Dream Chaser spaceplane built to go into orbit is starting to look the part. Its foldable wings and fuselage are covered in custom-fitted ceramic tiles to shield the spacecraft’s composite structure from the scorching heat of atmospheric reentry as it flies back to Earth. It has its landing gear, and technicians buzz around the vehicle to add the finishing touches before it leaves the factory.
Inside the spacecraft, workers are installing the final ducts for the environmental control system, which will make the pressurized compartment within Dream Chaser livable for astronauts at the International Space Station. The Dream Chaser’s job, at least for now, is to ferry cargo to and from the research complex orbiting some 240 miles (385 kilometers) above Earth. It will launch on top of a conventional rocket, maneuver in space like a satellite, and then land on a runway.
