Humans’ Endogenous Retroviruses Influence Our Brain Development

Humans’ Endogenous Retroviruses Influence Our Brain Development






A recent article in ScienceDaily based on a publication in the journal Cell Reports describes a hot topic in neurobiology: the contribution of endogenous retroviruses (ERVs) towards human brain development (1,2). Perhaps the most famous retrovirus is HIV, the Human Immunodeficiency Virus, shown in Figure 1. Unlike HIV, however, ERVs are […]

Physicists Cool Microscopic Drum to Near Absolute Zero






According to a paper recently published in Nature, researchers at the National Institute of Standards and Technology (NIST) have cooled a vibrating drum to an unprecedented one-fifth of a quantum of energy, approaching the previously perceived limit of absolute zero (1). Scientists use temperature to measure the thermal motion of […]
