Instead of traipsing through Florida in search of the Fountain of Youth, Spanish explorer Juan Ponce de León might have been better off turning his search inwards. More specifically, he should have turned his attention to a region of the brain called the hypothalamus. At least that’s what research carried out on mice by scientists at New York’s Albert Einstein College of Medicine of Yeshiva University suggests. They found that the hypothalamus controls many aspects of aging, opening up the potential to slow down the aging process by altering signal pathways within that part of the brain.  Read More

Fluorescent near-infrared waves pass readily through a mouse's tissues to reveal its brigh...

There are several techniques used by researchers and physicians to image the internal organs of people and animals, but each of these techniques have their shortcomings. X-rays and computed tomography (CT) scanning, for instance, involve exposing the subject to radiation. Magnetic resonance imaging (MRI) is safer, although subjects must sometimes ingest a contrasting agent in order to obtain more distinct images. The use of injected colored fluorescent proteins is another approach, but has been limited by the fact that hemoglobin in the subject’s blood absorbs much of the wavelength of the light used for imaging. Now, however, scientists from New York’s Albert Einstein College of Medicine of Yeshiva University have engineered a new fluorescent protein that sidesteps this limitation.  Read More
