NASA's Space Biology Program will fund 26 proposals to investigate how microbes, cells, plants and animals respond to changes in gravity. The research will be conducted aboard the International Space Station. The research will help uncover new basic knowledge that other NASA researchers and engineers can use to solve problems confronting human exploration of space or that could lead to new biological tools or applications on Earth. Proposals were in response to the NASA Research Announcement (NRA) NHH14ZTT001N, "Spaceflight Research Opportunities in Space Biology." The selected proposals come from 17 institutions in nine states and include 16 principal investigators who will be receiving their first Space Biology grant award. When fully implemented, the grants are worth a total of about $12.6 million during a one- to three-year period. The research will apply 21st-century genetics theories and new tools to study RNA and DNA. The objective is to learn how these building blocks of life regulate and sustain normal health, repair injuries and regulate growth, metabolism, reproduction and development during adaptation to microgravity. The space station will be used as a platform to study the behavior and evolution of microbes and evaluate the effects of long-term spaceflight on additional organisms such … Continue reading →

A 33-year-old University Place high school teacher pleaded guilty Thursday to having sex with a 17-year-old female student. Michael Allen, a biology teacher at Curtis High School, made the guilty plea in Pierce County Superior Court to charges of first-degree sexual misconduct with a minor and violation of a no-contact order. According to court documents, Allen had sex multiple times with the 17-year-old student. After he was arrested and charged, Allen continued to communicate with the victim, ignoring the court's no-contact order. He is scheduled to be sentenced Oct. 2. "Our schools should be safe havens," said Prosecutor Mark Lindquist. "This teacher abused the trust of his position and is being held accountable." Court files show that Allen and the victim, who was his teacher's aide, began exchanging phone calls and text messages in January 2014. On Jan. 17, school administrators learned the two were spending time together, and they placed Allen on administrative leave. He was told not to contact the victim. During an internal investigation, administrators reviewed the victim's phone records and found thousands of messages she exchanged with Allen, including after Allen was placed on leave, according to the case file. School administrators contacted the University Place … Continue reading →

A study recently published in the journal Carcinogenesis by researchers at the University of Kansas shows a new role for the protein adenomatous polyposis coli (APC) in suppressing colorectal cancer -- the second-leading cause of cancer-related deaths in the U.S. Lead author Kristi Neufeld, associate professor in the Department of Molecular Biosciences and co-leader of the Cancer Biology program at the KU Cancer Center, has spent the better part of her career trying to understand the various activities of APC, a protein whose functional loss is thought to initiate roughly 80 percent of all colon polyps, a precursor to colon cancer. Neufeld, along with her postdoctoral fellow Maged Zeineldin, undergraduate student Mathew Miller and veterinary pathologist Ruth Sullivan, now reports that APC found in a particular subcellular compartment, the nucleus, protects from inflammation as well as tumor development associated with chronic colitis. Whether APC reaches the nucleus may well affect the ability of intestinal stem cells to produce differentiated cells with specialized functions, Neufeld said. "It's not widely appreciated, but there is still plenty of cell growth going on in adults, with the colon being a good example," she said. "On average, we shed and replace about 70 pounds of … Continue reading →
