Plants That Are Predators

New York Times

Quoted: “In environments that are sunny and moist but nutrient-poor, the capture of prey can give plants a real competitive advantage,” said Thomas Givnish, a professor of botany at the University of Wisconsin-Madison. Carnivorous plants thrive in open bogs; in damp, fireswept sand; by roadside puddles; in the leached mud of a mountainside — bright, sodden spots where competitors are negligible, the insects gullible, and nutrients alone limit plant growth.

7 key questions about our newly discovered human ancestor, answered

Mashable

In groundbreaking new research published on Thursday, a new species of human relative has been discovered in South Africa. The findings, published in the journal eLife and reported in the October issue of National Geographic, detail the new species, known as Homo naledi, which was found in a remote cave chamber that also contains many other bones yet to be investigated.

Researchers Announce New Human-Like Species: Homo Naledi

Wisconsin Public Radio

Scientists in South Africa welcomed a new species into the human family tree this morning. Its name: Homo naledi. It’s slim and stands at under five feet tall with feet and hands similar to humans and a brain a third the size of ours, according to researchers.

Climate change affects lakes, walleye in complex ways

Scientists are still trying to figure out how a changing climate affects walleye and other species of fish. Most don’t expect the walleye to be a winner. As global climate change continues delivering warmer temperatures and heavier rains to Minnesota, lakes and their inhabitants will feel it. “One of the places you expect climate change to make a big difference is in changing the mix of species that do best in a lake,” said John Magnuson, director emeritus of the Center for Limnology — the study of inland waters — at the University of Wisconsin-Madison.

Proposed fetal tissue ban raises alarm for Wisconsin researchers

Science/AAAS

A Wisconsin bill that would limit the research use of fetal tissue from abortions is gaining momentum, over the protest of scientists who say the measure would stifle progress in disease research. The bill, approved today by a committee in the state assembly and expected to win the support of the full assembly this fall, is the first in what many predict will be a series of battles waged at the state level against the distribution and use of fetal tissue.

6 Tiny Cavers, 15 Odd Skeletons, and 1 Amazing New Species of Ancient Human

The Atlantic

Lee Berger put his ad up on Facebook on October 7th, 2013. He needed diggers for an exciting expedition. They had to have experience in palaeontology or archaeology, and they had to be willing to drop everything and fly to South Africa within the month. “The catch is this—the person must be skinny and preferably small,” he wrote. “They must not be claustrophobic, they must be fit, they should have some caving experience, climbing experience would be a bonus.”

Remains of Humanlike Ancestors Found in South Africa

Wall Street Journal

Researchers in South Africa discovered extensive remains of a previously unknown humanlike species in a subterranean boneyard, highlighting an early offshoot of humankind and raising questions about the origins of ritual burial and self-awareness, the scientists announced on Thursday.

This Face Changes the Human Story. But How?

National Geographic

A trove of bones hidden deep within a South African cave represents a new species of human ancestor, scientists announced Thursday in the journal eLife. Homo naledi, as they call it, appears very primitive in some respects—it had a tiny brain, for instance, and apelike shoulders for climbing. But in other ways it looks remarkably like modern humans. When did it live? Where does it fit in the human family tree? And how did its bones get into the deepest hidden chamber of the cave—could such a primitive creature have been disposing of its dead intentionally?

Fossils found in African cave are new species of human kin, say scientists

The Washington Post

The two amateur cavers had to feel their way along the cave’s winding passages, crawl on their stomachs through an opening less than 10 inches high, ascend a jagged wall, cross a narrow ledge dubbed the “Dragon’s Back,” and make a 400-foot descent, sideways, through a vertical crack before finally arriving at the prize: a 30-foot-long chamber probably between 2 million and 3 million years old.

The Quintessential College Experience, Without The Big Bills

National Public Radio

Going to college today is a very different experience than it once was. The cost has soared, and the great recession cut into many of the assets that were supposed to pay for it. This week All Things Considered is talking with young people — and in some cases their parents — about the value of school and about their choice of what kind of college to attend.

Morgridge matching gift to UW exceeds expectations

Wisconsin Radio Network

A $200 million gift to the University of Wisconsin-Madison will help to attract and keep top-quality faculty, and has grown larger and faster than expected. UW alumni John and Tashia Morgridge put up $100 million dollars last year and urged UW supporters to match it. They figured that would take up to three years, but it only took seven months to raise an additional 125-million.

Gaydar is officially not a thing

Cosmopolitan

You know your friend who knows, just KNOWS with absolute certainty, that the fit guy in your office is 100% gay, just by looking at him and analysing his *vibe*? They are wrong. Well, maybe. The fit guy in your office might be gay. But your friend is wrong about her always spot-on sensor for homosexuality, aka the gaydar. Because science has just proved that gaydar is not a thing.

New study finds that your ‘gaydar’ is terrible

The Washington Post

A new study suggests that ’gaydar’ — the sixth sense by which many insist they can just tell that someone they meet isn’t heterosexual — is bad in two big ways. For starters, it doesn’t work. But more importantly, the concept of gaydar may be pretty harmful. It may — big surprise here, guys — just be an excuse to revel in harmful stereotypes about LGBTQ people.

Meet the New Math Instruction, Same as the Old Math Instruction

WUWM

Common Core standards have been a political flash point since they were introduced and implemented.  Some believe they’re an unwanted government intrusion into local control of schools, while others say nationwide standards are necessary to ensure a quality education across the country. Jordan Ellenberg, a math professor at UW-Madison, falls under the latter category.

Faculty members think massive donation will help retain top professors at U of Wisconsin Madison

Facing what is sure to be a difficult retention season, given this year’s battles over the future of higher education funding and tenure in Wisconsin, the University of Wisconsin at Madison is today announcing the results of a massive donation-matching campaign aimed at recognizing top faculty members with endowed chairs.

Student Loans: Schools Want the Sky to Be the Limit

Bloomberg Business

Some lower-priced public universities are fine with introducing limits on student debt. The amount graduate students are allowed to borrow is “a little outrageous right now,” says Susan Fischer, who oversees financial aid at the University of Wisconsin at Madison. Others say graduate students should be trusted to understand how to manage their financial obligations. “They know what they are doing,” says Jonathan Burdick, vice provost for enrollment at the private University of Rochester. “People are not as dumb as the public dialogue seems to think they are.”

Scenes from Chancellor’s Convocation

Flu study highlights risks of banning ‘dangerous’ research, investigators say

Science

A lab at the center of a longstanding controversy about dangerous virus research has engineered heartier influenza viruses that could streamline vaccine production. The researchers contend that their findings may help bring future pandemics under control faster—but the study also demonstrates the risk of curtailing so-called gain-of-function (GOF) studies, in which viruses are made more transmissible or more pathogenic, the researchers argue.

Where Scott Walker Got His Utilitarian View of Higher Education — and Why It Matters

Chronicle of Higher Education

In the spring of 1990, Scott Walker, then a senior at Marquette University, decided to leave college before finishing his degree. A job in finance had opened up at the American Red Cross in Milwaukee, and Mr. Walker, now the governor of Wisconsin and a Republican candidate for president, leapt at the opportunity. “Certainly, I wanted an education for more than a job,” he has since said, “but my primary purpose was to get a job.”
