Study pinpoints brain cells that trigger sugar cravings and consumption

by Jennifer Brown, University of Iowa The hormone FGF21 is made in the liver and acts in the brain to suppress sugar intake and the preference for sweet taste. The cartoon illustrates the role FGF21 plays in food choices.Understanding the biological mechanisms that control sugar intake and preference for sweet taste could have important implications...

Engineering and philosophy combine for an emerging understanding of smell

by Brandie Jefferson, Washington University in St. Louis How does the brain detect smells? To find out, you could rely on biological sciences, using high tech imaging methods, or studying anatomical diagrams. You could even get philosophical and ask, “What is smell, anyway?” Or, you could turn to engineering. That’s what ShiNung Ching, an associate...

New adjuvant successful in extending immunity against HIV

ATLANTA – Researchers at the Yerkes National Primate Research Center and the Emory Vaccine Center (EVC) are first to show a new adjuvant, 3M-052, helps induce long-lasting immunity against HIV. The study results are published today in Science Immunology. In this pre-clinical study that included 90 rhesus monkeys, the researchers showed 3M-052, a new, synthetic...

CANCER AND CHEMO TEAM UP TO MAKE NEUROPATHY WORSE

Contrary to common medical guidance, chemotherapy does not appear to be the only culprit in neuropathy, a neurological side effect of cancer treatment, according to a new study in rats. Cancer itself contributes heavily, too, and the stresses on neurons appear far worse than the sum of the two causes. “There was some distress caused...

New findings redefine organisation of the claustrum

Researchers from Karolinska Institutet and Nanyang Technological University (NTU) in Singapore have found that the claustrum is organized into functional connectivity modules rather than a hub-like structure, which up until now, was the prevailing idea. The study was recently published in Current Biology. “We found that the synaptic connectivity between the cortex and claustrum is...
