New Discovery Could Lead to a Safer Solution to Plastic Pollution
Polyethylene terephthalate (PET) is a commonly used resin of the polyester family used in the fibers for clothing and liquid containers. In 2015 alone, 56 million tons of PET was produced. Although recyclable, with 1.5 billion pounds recovered annually in the United States, PET is not biodegradable and is a major presence in landfills. Screening 250 samples of contaminated soil, waste water and sludge from a bottle recycling factory for microorganisms that can grow on PET, a team of Japanese scientists has discovered a bacterium, Idoenella sakaiensis, that can break down this tough plastic. Recently spotlighted as a major breakthrough of 2016 by the American Chemical Society, research on the bacterium continues as scientists seek to unlock the mechanism behind the biodegradation pathway that was previously thought to be impossible. Professor Kenji Miyamoto, one of the study authors, said, “This is the first PET-degrading bacterium found [with potential] to develop a new and nature-friendly system”.

Trump Asks NIH Director Francis Collins to Stay On
Last Thursday, on the eve of the inauguration, the National Institutes of Health (NIH) announced that Dr. Francis Collins has been asked to continue his role as NIH director by the Trump administration for an unspecified time. This eleventh hour development came as Collins received back the letter of resignation he had sent late last year, something all presidential appointees do. If asked to stay on through this presidential term, Collins, part of Obama’s science ‘dream team’, would be the first NIH director since the 1970s to be chosen by two presidents.
Ezekiel Emanuel, a bioethicist at the University of Pennsylvania said, “In general, I think more than eight years has not been a good idea. There’s a cycle, and eight years is hard to have new ideas and new energy.” Nonetheless, Collins, a National Academy of Sciences member who led the human genome project and a highly vocal Christian apologist, would serve as an effective bridge between the research community and the new Republican administration to secure much needed funding for basic research. Tony Mazzashi, senior director for policy and research at the Association schools and Programs of Public Health in Washington DC said, “ I think everyone in the research community will be thrilled.” (Jocelyn Kaiser, Science)
Novavax Starts New Clinical Trial in Bid to Prove Failed RSV Vaccine
Respiratory Syncytial Virus (RSV) is a significant public health burden, infecting almost all children by age 2, with 5 to 20 out of 1,000 requiring hospitalization and with a mortality rate of 8 to 34 out of 10,000. Unfortunately, the development of an effective vaccine has been challenging. In the late 1960s, an RSV vaccine for infants devastatingly failed clinical trials with 80% of children receiving the shot being hospitalized. Recent advances in immunology and the RSV vaccine target has led to a new generation of potentially safer and more effective vaccine candidates from industry giants Novavax, GlaxoSmithKline, Global Vaccines, AstraZeneca and MedImmune. Also being explored is vaccination of expectant mothers to protect infants.
However, the field took a hit last year when Novavax’s candidate vaccine failed its phase 3 clinical trials, resulting in a 30% layoff of its workforce. Nonetheless, last Thursday, the company announced that it has started a new phase 2 trial on older adults in the southern hemisphere. “We expect the results from this trial to inform the next steps in our older adults program and would ensure we maintain our leadership position in this very attractive market opportunity,” said Stanley Erck, president and CEO of Novavax.
