91̽»¨ biologist Dee Boersma and her colleagues combed through 28 years’ worth of data on Magellanic penguins to search for signs that natural selection — one of the main drivers of evolution — may be acting on certain penguin traits. As they report in a paper published Sept. 21 in The Auk: Ornithological Advances, selection is indeed at work on the penguins at the Punta Tombo breeding site in Argentina.

Amid a decline in funding for scientific research, the Howard Hughes Medical Institute is partnering with the Bill & Melinda Gates Foundation and the Simons Foundation to launch a new Faculty Scholars program. Announced Sept. 22 by HHMI, the inaugural crop of early-career scientists includes 5 faculty members from the 91̽»¨.

91̽»¨ researchers are part of a national team that will study the baby teeth of children who have siblings with autism to determine if prenatal exposure to chemicals increases their risk of developing the disorder. The study will involve testing children’s teeth for levels of environmental chemicals that they might have been exposed to in the womb, a critical time for neurodevelopment. Additionally, for a smaller number of children whose genetic data has been collected, the researchers hope…

Researchers at the 91̽»¨ are among the winners of a startup challenge to shorten the transition time from lab bench to patient. The team, including members of professor Suzie Pun’s research group in the 91̽»¨Department of Bioengineering, was selected based on its proposal and business plan to develop a targeted drug delivery system for breast cancer.

The world’s attention is now on Proxima Centauri b, a possibly Earth-like planet about 4.22 light-years away. It’s in its star’s habitable zone — but could it in fact be habitable? If so, the planet evolved very different than Earth, say researchers at the 91̽»¨-based Virtual Planetary Laboratory.

“Interscatter” communication developed by 91̽»¨engineers allows power-limited devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches.

91̽»¨ biologist Peter Ward’s body of research has helped policymakers recognize the impact nautiluses have on ocean ecosystems, as well as how they can — and cannot — replenish their numbers in the face of unrestricted, unregulated fishing. At a CITES meeting in September, Ward and his team hope nautiluses will get much-needed protections from trade and harvesting.

At the USENIX Security Conference in Austin, Texas, a team of 91̽»¨ researchers on Aug. 12 presented the first-ever comprehensive analysis of third-party web tracking across three decades and a new tool, TrackingExcavator, which they developed to extract and analyze tracking behaviors on a given web page. They saw a four-fold increase in third-party tracking on top sites from 1996 to 2016, and mapped the growing complexity of trackers stretching back decades.

A dozen scientists and engineers from the 91̽»¨ have been elected to the Washington State Academy of Sciences. According to a statement released by the organization, the new members were selected for “their outstanding record of scientific achievement and willingness to work on behalf of the academy in bringing the best available science to bear on issues within the state of Washington.” Three of the new members from 91̽»¨were chosen because they had been elected recently to…
