Two novel hypotheses have been proposed that address the “two-fold cost of sex”: one of the biggest enigmas in the evolution of sexual reproduction.

Research examining traces of parasites in medieval Cambridge residents suggests that monks were almost twice as likely as ordinary townspeople to have intestinal worms – despite monasteries of the period typically having far more sanitary facilities.

Rachel Letteri, an assistant professor of chemical engineering at the University of Virginia, has received a $1.8 million Maximizing Investigators’ Research Award for Early-Stage Investigators from the National Institutes of Health to unlock the enormous promise of peptides as medicine.

Stanford engineers created a more efficient and flexible AI chip, which could bring the power of AI into tiny edge devices.

Metal parts made using laser-based additive manufacturing (AM) can have residual strain resulting from rapid heating and cooling during printing. Annealing parts after printing reduces the strain but can cause unwanted structural changes. Researchers used neutron diffraction and neutron imaging to measure strain and determine optimal annealing for metal AM parts.
