Escondido, California -  The Ione and Paul Harter Animal Care Center nursery at the San Diego Zoo Safari Park received a trio of new arrivals this week: three red-necked wallaby joeys. The female joeys, ranging in age from 5 to 6 months, are being hand raised until they are old enough to join the Safari Park’s mob of wallabies.

Washington, DC - Researchers at the National Institute of Standards and Technology (NIST) continue to pioneer new antenna measurement methods, this time for future 5G wireless communications systems.

Rochester, Minnesota - For years, researchers have known that our genome is protected by a system of detection, evaluation and repair processes that activate any time DNA damage occurs. Upon detection, the damage is assessed, repaired in one way or another, or, if it can’t be repaired the cell is cued to self-destruct. Much of that effort is set in motion by a signaling process involving the protein ubiquitin. Enzymes called ubiquitin ligases are charged with the task of tagging the damaged DNA with this ubiquitin protein to call in more help. What hasn’t been clear is how two of the key enzymes that mark the sites of DNA damage and amplify the repair response are called to action. Researchers theorized there was another actor involved, a missing link. Now Mayo Clinic researchers have discovered that link.

Rochester, Minnesota - When you think of dementia, most people automatically think of Alzheimer's disease, too. But, under a new definition of Alzheimer's, the two terms no longer will be considered interchangeable.

Rochester, Minnesota - Despite temperatures expected to hover around 39 degrees on April 5 here in the still snow-capped Bold North, the Minnesota Twins hosted the Seattle Mariners for their home opener at Target Field. (No word on whether Ichiro and company brought hand warmers.) One fan braving Minnesota's winter revival to take in the game was Kyle Traynor, M.D. But Dr. Traynor, a Mayo Clinic OB/GYN specialist, took a chair in the Twins' press box, where he served as one of the team's three official scorers.
