Bacteria In Worms Make A Mosquito Repellent That May Be Better Than DEET

National Public Radio

A study published Wednesday in Science Advances by University of Wisconsin–Madison researchers has found that a compound derived from these bacteria is three times more potent than DEET in repelling mosquitoes. More research must be done to demonstrate its safety, but this bacterial chemical could play an important role in the fight against mosquito-borne illness.

Bacterial compounds may be as good as DEET at repelling mosquitoes

Science News

Molecules made by bacteria keep mosquitoes at bay, researchers report January 16 in Science Advances. Tests suggest the compounds also deter two other mosquito species: Anopheles gambiae, a major malaria carrier, and Culex pipiens, which can carry the West Nile virus.Though DEET is considered safe for human use and effective against mosquitoes, it doesn’t hurt to have more lines of defense against the disease-transmitting insects, says coauthor Susan Paskewitz, an entomologist at the University of Wisconsin–Madison.

Antarctica ice melt has accelerated by 280% in the last 4 decades

The researchers, led by Richard Levy of New Zeland’s GNS Science and Victoria University of Wellington and Stephen Meyers of the University of Wisconsin-Madison, were able to recreate a broad history of the Antarctic ice sheet going back 34 million years to when the ice sheet first formed — documenting multiple cycles of ice growth and decay resulting from natural variations in the planet’s tilt.

Ongoing shutdown means scrambled travel plans, collaboration for higher ed researchers

Inside Higher Education

The ongoing federal shutdown is already creating headaches for scientists by hindering research planning and putting an abrupt halt to travel for some academics. But its worst effects will materialize in the coming weeks, should a stalemate between the White House, Republicans and congressional Democrats continue, researchers and university leaders said.

50-million-year cooling trend is reversed

“We can use the past as a yardstick to understand the future, which is so different from anything we have experienced in our lifetime,” said John Williams, a palaeo-ecologist at the University of Wisconsin-Madison in the US.

The biggest science stories of 2018: From the edge of the solar system to crises on Earth – The Washington Post

Washington Post

It was the year we left the heliosphere for the second time ever, and the year we got closer to the sun than ever. A year of biomedical breakthroughs and deadly disease outbreaks. It was a year in which humanity broke some crucial climate records (and not in a good way). IceCube is among the year’s top science stories, though Washington Post does not mention UW–Madison.

What We Learned in 2018: Science

New York Times

One team of scientists visualized the threat communication systems within plants that help them fight back when under attack. Others presented the tantalizing suggestion of plant consciousness using anesthetic gas. And in rain forests, some plants’ fruits seem to send careful messages to specific animals, in order to spread their seeds.

Climate Change Is Reversing a 50-Million-Year-Old Cooling Trend

The study’s lead author, Kevin Burke, worked with paleoecologist Dr. John Williams of the University of Wisconsin-Madison to assess the climatic characteristics of several geologic time periods, including the Early Eocene (beginning 56 million years ago), the mid-Pliocene (beginning 3.3 million years ago), the Last Interglacial (beginning 130,000 years ago), the mid-Holocene (beginning 7,000 years ago), the pre-industrial era (beginning in 1750), and the early 20th century.

UW-Madison climate study: Greenhouse gas levels high, warming likely

Milwaukee Journal Sentinel

Levels of heat-trapping greenhouse gases have surpassed those from any point in human history and by 2030 are likely to resemble levels from 3 million years ago when sea levels were more than 60 feet higher than today and the Arctic was forested and largely ice-free, according to a new paper by researchers at the University of Wisconsin-Madison.

In 200 years, humans reversed a climate trend lasting 50 million years, study says

During that ancient time, known as the mid-Pliocene epoch, temperatures were higher by about 2 to 4 degrees Celsius (3.6 to 7.2 degrees Fahrenheit) and sea levels were higher by roughly 20 meters (almost 66 feet) than today, explained Kevin D. Burke, lead author of the study and a researcher and Ph.D. candidate at the Nelson Institute for Environmental Studies at the University of Wisconsin-Madison.

“If we think about the future in terms of the past, where we are going is uncharted territory for human society. We are moving towards very dramatic changes over an extremely rapid time frame, reversing a planetary cooling trend in a matter of centuries,” says the study’s lead author, Kevin Burke, a graduate student at the University of Wisconsin-Madison (UW-Madison).

A Sister Bay youth who lost her father to cancer gets a needed scholarship

Door County Daily News

A new tuition program at U-W Madison is keeping Mackenzie Straub’s dreams of becoming a teacher alive. Paying for college seemed to be out of reach when her father died from cancer and the family’s menswear store closed. Now, Straub’s dream is getting a big boost from Bucky’s Tuition Promise a program that provides free tuition to qualifying students.

UW-Madison scholarship covers tuition for 796 students. This is one freshman’s story.

Wisconsin State Journal

Bucky’s Tuition Promise pledges to cover four years of tuition and fees — a total of $10,555 per year — for all incoming in-state freshmen whose families’ adjusted gross income is at or below $56,000, roughly the state’s median family income. Transfer students from Wisconsin meeting the same criteria will receive two years of tuition and fees.
