Ultrathin clay membrane layers offer low-cost alternative for extracting lithium from water

Lithium, the lightest metal on the periodic table, plays a pivotal role in modern life. Its low weight and high energy density make it ideal for electric vehicles, cellphones, laptops and military technologies where every ounce counts. As demand for lithium skyrockets, concerns about supply and reliability are growing.

To help meet surging demand and possible supply chain problems, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed an innovative technology that efficiently extracts lithium from water. Several team members also hold joint appointments with the Pritzker School of Molecular Engineering (PME) at the University of Chicago.

The findings appear in the journal Advanced Materials.

Semiconducting polymers and collagen combine to create safe, green wearable tech

The world of wearable technology—such as sensors and energy-producing devices—is expanding, thanks to new research into a unique combination of materials that are flexible, safe to use on or inside the human body, and environmentally friendly.

Dr. Simon Rondeau-Gagné and a team of collaborators and graduate students have used the Canadian Light Source (CLS) at the University of Saskatchewan to show that semiconducting polymers and collagen—the main component of human skin—can be combined to create “that are more efficient, more conformable and specifically… more green as well.”

Collagen provided both the skin-like rigidity and elasticity (or bendability) the researchers were looking for in “a platform that can be integrated with something like the human body,” said Rondeau-Gagné, an associate professor in the Department of Chemistry and Biochemistry at the University of Windsor.

New research reveals how male and female brains process regret and change decisions

A traditionally overlooked type of RNA plays an important role in promoting resilience to depression—but only in females. According to a new study led by the Icahn School of Medicine at Mount Sinai, researchers have now discovered a novel role this molecule plays in how the female brain makes decisions. The authors revealed brain-region-specific and sex-dependent effects of this biomarker, translated from humans to animals, on how individuals make only certain types of choices. This study uncovered differences in how each sex decides whether to change their minds after making mistakes, including when to cut their losses and move on as well as how they process regrets about missed opportunities.

This research sheds important light on how specific types of decisions that could negatively impact mood engage the male and female brain in very different ways. The study, published July 11 in Science Advances, using laboratory animal models, helps uncover new biological and psychological mechanisms that may be linked to psychiatric vulnerabilities.

Women are twice as likely to develop depression than men. Furthermore, depression can manifest with different symptoms between the sexes, including alterations in negative rumination on the past. However, the neurobiological mechanisms underlying these differences remain unclear.

Twist To the M-ax(is): New Twist Platform Opens Path to Quantum Simulation of More Exotic States of Matter

Researchers introduce a new class of twistable materials, unlocking unprecedented quantum possibilities. Twisted materials—known as moiré structures—have revolutionized modern physics, emerging as today’s “alchemy” by creating entirely new phases of matter through simple geometric manipulation. The term “moiré” may sound familiar—it describes the st

Role of plasmin in metastatic tumors

FasL is an immune cell membrane protein that triggers a programmed cell death called apoptosis. Activated immune cells, including CAR-T cells made from a patient’s immune system, use apoptosis to kill cancer cells.

The team discovered that in human genes, a single evolutionary amino acid change — serine instead of proline at position 153 — makes FasL more susceptible to being cut and inactivated by plasmin.

Plasmin is a protease enzyme that is often elevated in aggressive solid tumors like triple negative breast cancer, colon cancer and ovarian cancer.

This means that even when human immune cells are activated and ready to attack the tumor cells, one of their key death weapons — FasL — can be neutralized by the tumor environment, reducing the effectiveness of immunotherapies.

The findings may help explain why CAR-T and T-cell-based therapies can be effective in blood cancers but often fall short in solid tumors. Blood cancers often do not rely on plasmin to metastasize, whereas tumors like ovarian cancer rely heavily on plasmin to spread the cancer.

Significantly, the study also showed that blocking plasmin or shielding FasL from cleavage can restore its cancer-killing power. That finding may open new doors for improving cancer immunotherapy.
