Where did western honey bees come from? New research finds the sweet spot
Science Daily - 3 Dec 2021 22:14
For decades, scientists have hotly debated the origin of the western honey bee. Now, new research has discovered these popular honey-producing bees most likely originated in Asia.
Daytime meals may reduce health risks linked to night shift work
Science Daily - 3 Dec 2021 22:14
A small clinical trial has found that eating during the nighttime -- like many shift workers do -- can increase glucose levels, while eating only during the daytime might prevent the higher glucose levels now linked with...
Brain drain: Scientists explain why neurons consume so much fuel even when at rest
Science Daily - 3 Dec 2021 22:14
Pound for pound, the brain consumes vastly more energy than other organs, and, puzzlingly, it remains a fuel-guzzler even when its neurons are not firing signals called neurotransmitters to each other. Now researchers ha...
Immune system-stimulating nanoparticle could lead to more powerful vaccines
Science Daily - 3 Dec 2021 22:14
Researchers designed a new nanoparticle adjuvant that may be more potent than others now in use. Studies in mice showed it significantly improved antibody production following vaccination against HIV, diphtheria and infl...
