Artificial Ovaries Can Reduce Symptoms Of Menopause, Researchers Find.

MIT Technology Review Share to FacebookShare to Twitter (12/5) reports that scientists are exploring whether using lab-made ovaries might reduce the symptoms of menopause. The research, carried out at Wake Forest Baptist Medical Center, shows that using “tissue engineering to construct artificial rat ovaries able to supply female hormones like estrogen and progesterone” was “better than traditional hormone replacement drugs at improving bone health and preventing weight gain.” MIT Technology Review says hormone replacement therapy can increase the risk of heart disease and breast cancer is not recommended for long-term us.

The Daily Mail Share to FacebookShare to Twitter (12/5, De Graaf) reports that “the research team isolated the two types of cells found in ovaries (theca and granulosa) from rats” in order to engineer the bioartificial ovary. The Daily Mail reports, “The study found that the cell-based constructs led to a substantially lower percentage of body fat levels than low-dose drug therapy and had the same results as animals with intact ovaries.”

Medical Xpress Share to FacebookShare to Twitter (12/5) reports, “The study looked at three areas commonly affected by the loss of ovarian function: body composition, bone health and uterine health,” all of which were better with cell treatment than traditional outcome.

Intellectual Property Law Expert Speaks At Women In Engineering Seminar.

La Porte County (IN) Life Share to FacebookShare to Twitter (12/1) reports Purdue West Lafayette hosted its Women in Engineering Seminar last month. Domenica Hartman of Hartman Global Intellectual Property Law spoke at the seminar, as “she has done for the last twenty years.” During her address, Hartman championed the mission of the Society of Women Engineers, and at the heart of her speech “was the message that ‘Engineering is Awesome.’” The article says female participation in engineering “has been lacking,” with just under 20 percent of bachelor’s degrees in engineering awarded to women. Thus, the article says, “encouragement and enticement are so vital to seeing the field level out on a more equal footing.”

Graduate Students Arrested During Protest Against Tax Reform Bill.

The Washington Post Share to FacebookShare to Twitter (12/5, Douglas-Gabriel) reports that outside House Speaker Paul Ryan’s office on Tuesday, eight graduate students were arrested during a protest against a provision in the Republican tax reform bill to treat higher education tuition benefits as income, which “students fear will make their education less affordable.” One arrested protester, Washington University in St. Louis doctoral candidate in astrophysics Benjamin Groebe, argued he and other research assistants will see their taxable income surge “to more than $71,000, despite only taking home a fraction of that amount.” According to ED data from the 2011-12 academic year, nearly 55 percent of graduate students’ adjusted gross income was below $20,000. Also on Tuesday, Association of Public and Land-grant Universities president Peter McPherson said in a letter to House and Senate leaders that the tuition exemption “is critical for developing the science and technology workforce pipeline that employers need to propel our nation’s economy forward.”

Student Loan Whistleblower Profiled.

The Chronicle of Higher Education Share to FacebookShare to Twitter (12/5) profiles Jon H. Oberg, a former ED researcher who “noticed something odd” in 2003. “Through a careful maneuver, Mr. Oberg realized, banks using federal money to issue loans to college students had devised a clever way to keep a lot more of that money than they were supposed to.” After “Congress voted to shut off that subsidy,” a number of banks “devised a system to essentially pass new loan money through old loan portfolios…thereby making hundreds of millions of dollars in excess profits.” After ED officials told Oberg “to find something else to work on,” he “he became a whistle-blower. He has spent the last 10 years helping government lawyers prove the scheme in court, as they tried to hold nine loan companies responsible.”
