New Tool Empowers Research on Key Proteins

A new single-protein analysis technique gives researchers an unprecedented ability to study proteins called scramblases, which have critical roles in biology. The development of the new technique, in a study led by investigators at Weill Cornell Medicine and Ruhr University Bochum in Germany, expands the toolkit available to cell biologists and biophysicists and could someday be useful in devising new strategies against multiple diseases.

Scramblases operate within cell membranes to rearrange the fat-related molecules, known as lipids, that make up those membranes. Their disruption of the usual layered organization of the membrane is essential for many important biological processes. In the study, published June 15 in Nature Structural & Molecular Biology, theresearchers developed a fluorescence imaging-based technique—the first of its kind—for measuring the activity rates of individual scramblase proteins. Their demonstrations of the technique uncovered new findings on key scramblases, and showcased the technique’s broad applicability.

Experimental Treatment Directly Kills Prostate Tumor Cells While Reawakening Antitumor Immunity

Prostate-targeted, engineered nanoparticles made of amorphous silica are effective in killing prostate tumors directly while enhancing anti-tumor immunity, according to a preclinical study led by investigators at Weill Cornell Medicine and the Cornell College of Engineering. The particles, derived from silicon dioxide, a common component of healthy foods or fossilized sedimentary structures from single-celled organisms, induced several complete remissions of aggressive tumors in mouse models, supporting the further investigation of their use in clinical trials.

Weill Cornell Medicine Scientist Receives Award for Research on New Ovarian Cancer Targets

Dr. Dan Landau, the Bibliowicz Family Professor of Medicine, and a member of the Sandra and Edward Meyer Cancer Center and the Englander Institute for Precision Medicine at Weill Cornell Medicine, has received a Lotus Award from the Pershing Square Foundation for research aimed at uncovering new immunotherapy targets in ovarian cancer.

The Pershing Square Foundation supports ambitious cancer research projects, and since 2025 has been funding ovarian cancer research with three-year grants of $750,000, now called Lotus Awards. Awardees were selected for their scientific rigor, originality and potential to drive meaningful advances in a disease where progress is urgently needed. Dr. Landau is one of eight recipients this year.

“We’re grateful for this opportunity to develop new therapeutic perspectives to benefit patients with this deadly but relatively under-studied form of cancer,” said Dr. Landau, who is also a core faculty member of the New York Genome Center.
