Air-bubble pockets created by slapping their legs on the surface help keep flat-tailed house geckos afloat as they dash across bodies of water, a study published in Current Biology suggests. "They are partially hydroplaning," said Jasmine Nirody, whose team filmed the geckos with high-speed video cameras to analyze the process.
Academics who work from home must observe a consistent schedule and set realistic long- and short-term goals, write Paul Frater, a Ph.D. candidate at the University of Iceland, and Lauren Sullivan, a postdoctoral researcher at the University of Minnesota. It also is helpful to have a separate office space and seek human interaction by working in areas such as coffee shops to battle feelings of isolation, they recommend in this commentary.
Some students at a Massachusetts high school are learning lessons in science and chemistry through forensics. Science teacher Trisha Cignetti says the lessons could help students interested in careers in criminal justice or those who might serve on a jury.
Slightly more than a quarter of educators say they would recommend a friend or colleague take up teaching as a career, according to the 2018 Schooling in America survey, which was run by a research firm and a group that advocates for school choice.

A study by Nevada higher-education officials found that 62.5% of students at two-year colleges who took 15 or more credits during their freshman year completed introductory math courses within the first year and a half of their studies in 2016, compared with 27.2% of students taking fewer credits. The data show similar results at four-year institutions.
Changing majors costs students more money and delays graduation, but research from EAB shows those who never changed their major are slightly less likely to graduate than students who switched in their sophomore year. However, Dhanfu Elston, Complete College America vice president for strategy, says colleges must do more to ensure students stay on track, especially when switching majors.
Higher-education leaders can improve the reputation of their institution and regain public trust by demonstrating financial efficiency and engaging more with their communities, writes Ohio State University professor Stephen Gavazzi. Leaders also must ensure that their research is beneficial to the public and focus on providing affordable access instead of higher rankings, he asserts in this commentary.
