Maine employers grapple with office policies amid constant change

Maine employers grapple with office policies amid constant change Many companies plan to continue experimenting with new ways of working that involve more flexibility and remote work options. Share Nate Wildes, owner of Flight Deck and executive director of Live + Work in Maine, at Flight Deck in Brunswick on July 16, 2021. Wildes said many Maine businesses haven t yet determined what their long-term work policies will be after the coronavirus pandemic. Shawn Patrick Ouellette/Staff Photographer Nearly 16 months after much of Maine’s workforce went remote, many businesses are preparing plans to reopen their offices. But after a year in which the only constant has been change, and with so many facets to creating a new normal – safety, employee satisfaction and a positive work culture chief among them – many employers have been hesitant to set any plans in stone. 

Nobel Prize awarded to immunogeneticist George Snell in 1980 to be auctioned

Nobel Prize awarded to immunogeneticist George Snell in 1980 to be auctioned Snell won the Nobel Prize for his discovery of HLA (Human Leukocyte Antigen). LOS ANGELES, CA .- The 1980 Nobel Prize in Physiology or Medicine, awarded to George D. Snell for science will be auctioned by Nate D. Sanders Auctions on July 29, 2021. Snell won the Nobel Prize for his discovery of HLA (Human Leukocyte Antigen), the genetic foundation of a body s immunological response to tissue and organ transplants, determining whether it accepts an organ or rejects it. His research conducted at Jackson Laboratory in Bar Harbor, Maine became the birth of transplantation immunology utilizing the histocompatibility system. The more antigens on the leukocytes they share, the more likely a tissue transplant is to survive. Prior to Snell s research, organ transplantation was entirely dependent on chance as to whether a genetic match would allow an organ to be accepted by its recipient; afterwards, the only imp

Genetic risks for nicotine dependence span a range of traits and diseases

Tags » Some people casually smoke cigarettes for a while and then stop without a problem, while others develop long-term, several packs-per-day habits. A complex mix of environmental, behavioral and genetic factors appear to raise this risk for nicotine dependence.  Studies of groups of twins suggest that 40 to 70 percent of the risk factors are heritable. Until recently, however, studies have only explained about 1 percent of the observed variation in liability to nicotine dependence, using a genetic score based on how many cigarettes a person smokes per day.  A study led by psychologists at Emory University offers a new model for examining this genetic risk. It leveraged genome wide association studies for a range of different traits and disorders correlated with nicotine dependence and explained 3.6 percent of the variation in nicotine dependence.
