International scientists rethink U.S. conference attendance
Opposition to Trump administration and fears of customs run-ins are shifting travel plans
The AI revolution comes to protein sequencing
New systems can identify unknown proteins in samples from diseased tissue, the environment, and archaeological sites
Are terminations of NIH grants wasting billions of taxpayer dollars?
DOGE argues killing grants saves money, but a Science analysis suggests more than $1.4 billion in sunk research costs may produce few results
NSF has awarded almost 50% fewer grants since Trump took office
The reasons aren’t clear—and the agency’s director claims the president’s policies haven’t slowed grant awards
Hedonic eating is controlled by dopamine neurons that oppose GLP-1R satiety | Science
Hedonic eating is defined as food consumption driven by palatability without physiological need. However, neural control of palatable food intake is poorly understood. We discovered that hedonic eating is controlled by a neural pathway from the peri–...
Running a genetic stop sign accelerates oxygen metabolism and energy production in horses | Science
Horses are among nature’s greatest athletes, yet the ancestral molecular adaptations fueling their energy demands are poorly understood. Within a clinically important pathway regulating redox and metabolic homeostasis (NRF2/KEAP1), we discovered an ...
Leucine aminopeptidase LyLAP enables lysosomal degradation of membrane proteins | Science
Breakdown of every transmembrane protein trafficked to lysosomes requires proteolysis of their hydrophobic helical transmembrane domains. Combining lysosomal proteomics with functional genomic datasets, we identified lysosomal leucine aminopeptidase (...
Chromatin accessibility landscape of mouse early embryos revealed by single-cell NanoATAC-seq2 | Science
In mammals, fertilized eggs undergo genome-wide epigenetic reprogramming to generate the organism. However, our understanding of epigenetic dynamics during preimplantation development at single-cell resolution remains incomplete. Here, we developed ...
Complex-frequency excitations in photonics and wave physics | Science
Closed, lossless optical cavities are characterized by a Hamiltonian that obeys Hermiticity, resulting in strictly real-valued resonance frequencies. By contrast, non-Hermitian wave systems are characterized by Hamiltonians with poles and zeros at ...

Equitable access needed in clinical research | Science
In her News story “Cornerstone medical ethics guidelines get a major update” (1 November 2024, p. 473), C. O’Grady describes recent changes to the Declaration of Helsinki (1). Although the revision includes improvements, O’Grady explains that some issues were overlooked, such as obligations to research participants and their communities. These oversights are particularly stark in tuberculosis (TB) research, and the resulting disparities illustrate the importance of addressing inequities systemically.
