Merons and antimerons

Bilayer hBN exhibits moiré polar domains that form networks of topological polar merons and antimerons. This symmetry breaking enables control over the topological properties in two-dimensional layered materials. The polarization field's winding is topologically non-trivial, resulting from a previously overlooked in-plane component.

Time-restricted fasting could cause fertility problems

A new study published in Proceedings of the Royal Society B found that time-restricted fasting affects reproduction differently in male and female zebrafish. After returning to normal food consumption levels, females increased offspring production at the cost of reduced egg quality, while male sperm quality also decreased.

Pilot study finds metabolic alterations related to sexual and physical abuse

A pilot study at the University of Eastern Finland found metabolites related to oxidative stress and transsulfuration to be associated with a history of sexual or physical abuse in depressed adolescent outpatients. The study's findings suggest that further research into the biological mechanisms underlying trauma is needed.

Alternative route used by specialized immune cells to colonize the embryonic brain suggests new approach to fighting fetal brain dysfunction

Researchers at Nagoya University found an alternative route for microglia colonization in the embryonic brain, suggesting a novel approach to combat diseases like fetal brain dysfunction. Macrophages can convert into microglia later in development, providing new insights into microglial plasticity and behavior.

Detecting stress in the office from how people type and click

A new study by ETH Zurich researchers has developed a model that can predict stress levels in the office based on typing and mouse behavior, finding stressed individuals type and move more erratically than relaxed ones. The approach could help prevent workplace stress early on with anonymized data protection.

Migratory birds can partially offset climate change

A new study found that migratory birds, such as the American Redstart, can delay their spring migration by up to 10 days and fly faster to reach breeding grounds, partially offsetting climate change impacts. However, this strategy comes with a decline in overall survival rates.

It’s all in the wrist: Energy-efficient robot hand learns how not to drop the ball

Researchers at the University of Cambridge designed a soft robotic hand that can grasp a range of objects using passive movement and tactile sensors. The hand successfully grasped 11 of 14 objects in tests, including a peach, computer mouse, and roll of bubble wrap, demonstrating its ability to predict when it might drop an object.
