Why late-night eating leads to weight gain, diabetes

Scientists have uncovered the mechanism behind why eating late at night is linked to weight gain and diabetes. The connection between eating time, sleep and obesity is well-known but poorly understood, with research showing that over-nutrition can disrupt circadian rhythms and change fat tissue.

Tentacle robot can gently grasp fragile objects

Taking inspiration from nature, researchers designed a new type of soft, robotic gripper that uses a collection of thin tentacles to entangle and ensnare objects, similar to how jellyfish collect stunned prey. Alone, individual tentacles, or filaments, are weak. But together, the collection of filaments can grasp and securely hold heavy and oddly shaped objects. The gripper relies on simple...

Hubble views a turbulent stellar nursery

The lives of newborn stars are tempestuous, as this image of the Herbig-Haro objects HH 1 and HH 2 from the NASA/ESA Hubble Space Telescope depicts. Both objects are in the constellation Orion and lie around 1,250 light-years from Earth. HH 1 is the luminous cloud above the bright star in the upper right of this image, and HH 2 is the cloud in the bottom left. While both Herbig-Haro objects are...

Scientist sues U.S. National Academy of Sciences after being ousted

Luis Jaime Castillo Butters, a prominent Peruvian archaeologist who was among the first members of the U.S. National Academy of Sciences to be removed after a 2019 bylaws update allowed expulsion for documented misconduct violations, filed a $5 million defamation lawsuit against the academy and NAS President Marcia McNutt this month. The suit alleges that “NAS and McNutt made false...

Fully mature hair follicles grown in cultures

A team of researchers from Japan studying the processes of hair follicle growth and hair pigmentation has successfully generated hair follicles in cultures. Their in vitro hair follicle model adds to the understanding of hair follicle development which could contribute to development of useful applications in treating hair loss disorders, animal testing, and drug screenings.
