Scientists at Ames National Laboratory have revealed the first unconventional superconductor with a chemical composition naturally found in the Earth’s crust. Named “miassite,” this mineral joins a rare league of only four natural substances capable of exhibiting superconductivity under laboratory conditions.

According to the research team’s study published in the journal Communication Materials, the discovery holds promise for future advancements in sustainable and cost-effective technologies.

“Viruses, infections, and pandemics have become recurrent features in our lives, profoundly impacting human existence and even extending their reach to animals. Despite this, accessible, rapid, and affordable virus detection methods have been lacking,” said Xingcai Zhang, PhD, researcher, Harvard University, told GEN. “Our study aims to visualize viral infection states, predict infection duration, unravel the infection process, explore inhibition methods, and contribute to understanding viral disease transmission and pathogenesis.”

Viral infection of cells causes stress resulting in cell morphology differences over time. This study leveraged those known morphological changes to discern between infected and non-infected cells in culture. The standard practice for identifying infected cells, the methyl thiazolyl tetrazolium (MTT) assay, requires the use of reagent treatments and chemical reactions which can take upwards of 40 hours per sample, which is destroyed in the process.

The method proposed in this paper uses a lensless light diffraction platform to detect diffraction patterns, which can be used to extract information such as contrast and inverse differential moment which are used to create diffraction fingerprints. The fingerprints can be monitored continuously in the same samples as there is no inherent damage to cells.

The recently approved drug motixafortide may help improve stem cell transplants for people with multiple myeloma. Learn more about this treatment:

However, Dr. Schulz cautioned, this finding is not definitive because the two drugs were not tested head-to-head in a randomized trial. A randomized clinical trial comparing the drugs “would have been a better and fairer comparison,” he said, since plerixafor and motixafortide both work by blocking a chemical signal that tells stem cells to stay in the bone marrow.

Finally, Dr. Crees and his colleagues did a series of experiments looking at the different types of blood-forming stem cells mobilized by G-CSF plus placebo, motixafortide, or plerixafor.

A study of more than 21,000 average risk patients at 186 sites across the U.S., led by Regenstrief Institute and Indiana University School of Medicine research scientist Thomas Imperiale, M.D., has found that the next-generation multi-target stool DNA colorectal cancer screening test detects 94% of colorectal cancers. This test has the best performance for detection of both colorectal cancer and advanced precancerous polyps of any noninvasive colorectal cancer screening test.

The study results are published in the New England Journal of Medicine.

“We found that the next-generation stool DNA test had a good balance of sensitivity—detecting disease—and specificity—low false positive results. Compared to the fecal immunochemical test (FIT), the next gen test had superior sensitivity for both colorectal cancer and advanced pre-cancerous polys, especially the subgroup of advanced polyps containing high grade dysplasia,” said Dr. Imperiale, first author of the study.

Researchers have found a way to stop active cancer cells in their tracks – meaning they can then be eliminated by new drug treatments.

A collaborative research project between the University of Dundee’s Drug Discovery Unit (DDU) and Queen Mary University of London, has identified chemical compounds, called tool molecules, that can halt active cancer cells.

The work, facilitated by the Chicago Quantum Exchange (CQE) and led by a team that includes UD, Argonne, JPMorgan Chase and University of Chicago scientists, lays groundwork for future applications—and highlights the need for cross-sector collaboration.

The third category, stochastic modeling, is used across the sciences to predict the spread of disease, the evolution of a chemical reaction, or weather patterns. The mathematical technique models complex processes by making random changes to a variable and observing how the process responds to the changes.

The method is used in finance, for instance, to describe the evolution of stock prices and interest rates. With the power of quantum computing behind it, stochastic modeling can provide faster and more accurate predictions about the market.

What can Titan’s methane-rich atmosphere teach us about finding life beyond Earth? This is what a recent study published in Planetary and Space Science hopes to address as a team of international researchers investigated the photochemistry of Saturn’s largest moon, which is also the only moon in the solar system with a dense atmosphere, to ascertain if the moon’s methane-rich atmosphere can support life. This study holds the potential to help researchers better understand the conditions necessary for life to emerge, along with where to search for it beyond Earth.

“Titan’s atmosphere works like a planetary-sized chemical reactor, producing many complex carbon-based molecules,” said Rafael Rianço-Silva, who is a master’s degree student at the University of Lisbon and lead author of the study. “Of all the atmospheres we know in the Solar System, the atmosphere of Titan is the most similar to the one we think existed on the early Earth.”

For the study, the team used the European Southern Observatory’s Very Large Telescope Ultraviolet and Visual Echelle Spectrograph (VLT-UVES) to conduct high resolution analyses of Titan’s hazy and methane-rich atmosphere. Using this data, the team identified possible traces of the tricarbon molecule (C3), which is known for being a building block for the development of complex molecules and has been previously identified in cometary comas and interstellar clouds, the latter of which was found using VLT-UVES. If confirmed, Titan will be the first planetary body to possess tricarbon either in its atmosphere or on its surface.
