A Promising Compound for Reversible Male Contraception

Researchers found that a small-molecule protein inhibitor—screened from billions of compounds and analyzed using structural insights from protein crystallography—reversibly suppresses male fertility in mice. The work addresses the pressing need for more contraceptive options that enable all individuals to control their own fertility. Read more »PPT-icon-35

Postdoctoral Fellowship Application Window to Open in October

Applications for the next round of ALS Collaborative Postdoctoral Fellowships are due November 1 for a start date of May 1, 2025. Fellows spend a year in residence at the ALS pursuing research projects in teams that include staff and the user community, and are exposed to current scientific challenges that can be tackled using advanced synchrotron radiation tools.

Mechanism of an Economical Way to Produce Al–Ce Alloy

A time-resolved diffraction study conducted at the ALS revealed mechanistic insight into a multi-step chemical reaction for the economical production of aluminum–cerium alloy, a high-performance material with superior temperature stability. The results provide crucial information for the application of the method on an industrial scale. Read more »

Reports from 2023 Science Visioning Workshops Published

The compiled reports from four ALS science visioning workshops held in 2023 are now published. The document reflects the user and broader scientific communities’ viewpoints on how the ALS’s science portfolio should evolve into the 2030s and where investments will be needed to realize the vision.
