Scientists Use Marine Robots to Detect Endangered Whales

Two robots equipped with instruments designed to “listen” for the calls of baleen whales detected nine endangered North Atlantic right whales in the Gulf of Maine last month. The robots reported the detections to shore-based researchers within hours of hearing the whales (i.e., in real time), demonstrating a new and powerful tool for managing interactions between whales and human activities.

The team of researchers, led by Woods Hole Oceanographic Institution (WHOI) scientists Mark Baumgartner and Dave Fratantoni, reported their sightings to NOAA, the federal agency responsible for enforcing the Marine Mammal Protection Act. NOAA Fisheries Service, in turn, put in place on Dec. 5 a “dynamic management area,” asking mariners to voluntarily slow their vessel speed to avoid striking the animals. (more…)

Yale Scientist Named One of ’10 People Who Mattered This Year’

Microbiologist Jo Handelsman has been named one of the “366 Days: Nature’s 10” people who “mattered” in 2012 by Nature Magazine. Handelsman, professor of molecular, cellular, and developmental biology and a national expert on science education, was recognized for her work showing gender bias in science. (more…)

Climate Change Threatens Giant Pandas’ Bamboo Buffet–and Survival

China’s endangered wild pandas may need new dinner reservations–and quickly, based on models that indicate climate change may kill off swaths of bamboo that pandas need to survive

In this week’s Nature Climate Change, an international journal, scientists from Michigan State University (MSU) and the Chinese Academy of Sciences provide comprehensive forecasts of how changing climate may affect the most common species of bamboo that carpet the forest floors of prime panda habitat in northwestern China. Even the most optimistic scenarios show that bamboo die-offs would effectively cause prime panda habitat to become inhospitable by the end of the 21st century.

The scientists studied possible scenarios of climate change in the Qinling Mountains in Shaanxi Province. At the northern boundary of China’s panda distributional range, the Qinling Mountains are home to about 275 wild pandas, which account for about 17 percent of the remaining wild population. The Qinling pandas, which have been isolated because of thousands of years of human habitation around the mountain range, vary genetically from other giant pandas. The geographic isolation of these pandas makes them particularly valuable for conservation, but vulnerable to climate change. (more…)

Half of Texans Prefer Faith over Science, According to UT/Texas Tribune Poll

AUSTIN, Texas — About half of Texas voters believe faith is a better guide than scientific evidence on most important questions, according to a recent University of Texas at Austin/Texas Tribune poll.

According to the poll, which surveyed Texans on a wide range of attitudes related to science and public policy, a similar proportion of voters said that “instinct and gut reactions” are just as good as the advice of scientists in most cases.

However, 66 percent of voters said politicians, when faced with a difficult decision, should follow the advice of relevant experts, even if it means going against their ideology. (more…)

It’s in the Genes: Research Pinpoints How Plants Know When to Flower

Scientists believe they’ve pinpointed the last crucial piece of the 80-year-old puzzle of how plants “know” when to flower.

Determining the proper time to flower, important if a plant is to reproduce successfully, involves a sequence of molecular events, a plant’s circadian clock and sunlight.

Understanding how flowering works in the simple plant used in this study – Arabidopsis – should lead to a better understanding of how the same genes work in more complex plants grown as crops such as rice, wheat and barley, according to Takato Imaizumi, a University of Washington assistant professor of biology and corresponding author of a paper in the May 25 issue of the journal Science.

Largest Meteorite Hunt in History Yields Treasure for UA

Thanks to the generosity of three professional meteorite hunters, the UA Lunar and Planetary Laboratory will own three samples of a rare kind of meteorite leftover from the earliest beginnings of the solar system.

To the untrained eye, the black, smooth-edged lump that is sitting under a glass cover looks similar to a piece of charcoal. But to scientists Dante Lauretta and Ed Beshore from the University of Arizona Lunar and Planetary Laboratory, it is one of the most intriguing stones they have ever seen.

“This meteorite is the oldest rock you’ll ever find on Earth. In fact, it formed 50 to 60 million years before the Earth even existed,” said Lauretta, who is a professor of planetary science and principal investigator of NASA’s OSIRIS-REx mission, which will send a spacecraft to return a sample from an asteroid in 2023.

Science Outreach : Getting Started is Easy!

Sharing scientific knowledge is a fundamental part of university life. Regardless of whether you’re an undergraduate or a tenured professor, everyone has the responsibility of spreading their knowledge as widely as possible.

Why would you want to, though? “For a variety of reasons,” answers William Raillant-Clark, Press attaché at Université de Montréal’s Office of Communications and Public Relations. “The media is an excellent vehicle for communicating your ideas or your discoveries to the general public, and it can also draw the attention of your research peers to your work. This is one of the reasons why funding partners and potential research directors take into consideration science outreach work.” (more…)

Children Don’t Give Words Special Power to Categorize Their World

COLUMBUS, Ohio – New research challenges the conventional thinking that young children use language just as adults do to help classify and understand objects in the world around them.

In a new study involving 4- to 5-year-old children, researchers found that the labels adults use to classify items – words like “dog” or “pencil” – don’t have the same ability to influence the thinking of children. (more…)
