The androgen receptor is a key transcriptional factor for the proper sex development -- especially in males -- and the physiological balance of all the tissues that express this receptor. The androgen receptor is involved in several pathologies and syndromes, such as the spinal and bulbar muscular atrophy or androgen insensitivity syndrome, among others, for which there is no specific treatment. Regarded as the main initial and progression factor in prostate cancer -- the second most common malignant disease in men in industrialized countries -- this receptor has been, for decades, the main therapeutical target for the treatment against this disease.

Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.

For a functioning brain to develop from its embryonic beginnings, so much has to happen and go exactly right with exquisite precision, according to a just-so sequence in space and time. It's like starting with a brick that somehow replicates and differentiates into a hundred types of building materials that also replicate, while simultaneously self-assembling into a handsome skyscraper replete with functioning thermal, plumbing, security and electrical systems.

Breaking a longstanding impasse in our understanding of olfaction, scientists have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.

Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study has found.

It may be better to let a mild fever run its course instead of automatically reaching for medication, new University of Alberta research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down naturally without medication. The health advantages of natural fever to humans still have to be confirmed through research, but the researchers say because the mechanisms driving and sustaining fever are shared among animals, it is reasonable to expect similar benefits are going to happen in humans.
