Prof. Richard Taylor’s research is mentioned in The Guardian article on why people should walk in nature in this time of crisis.

If you were in any doubt that it was OK to go outside, while keeping at least two metres away from others, the chief medical officer Chris Whitty told the BBC on Wednesday: “Being outside in the park is a very good thing to do.”

He would know. In the past decade, the scientific evidence that connection with nature has important therapeutic benefits for human mental health has mushroomed. Robust studies from disciplines across the world are demystifying what many intuitively know – that we often feel restored when we spend time in nature.

Tristan Ursell’s work featured in Quanta Magazine

Tristan Ursell at the University of Oregon, inspired by Kerr and Bohannan’s work, wanted to take it one step further. Although their study had shown that the distribution of organisms was key to the development of rock-paper-scissors, the environments in their experiments didn’t have physical barriers that would prevent the bacteria from moving about. The natural world is nothing like that: Whether a microbe is living on a plant’s roots or snuggled up somewhere in our intestines, its environment is filled with obstructions. Ursell, a biophysicist rather than a microbiologist, decided to create a series of computer models to see how physical obstacles could alter the rock-paper-scissors cycles.

Going into the project, Ursell expected that the obstacles might have minor consequences for the simulation. “I did not anticipate that it would in some cases completely flip over the stability,” he said.

Why Saving Single Species Isn’t Enough

Pitting two species against each other in an open space, for example, typically ended with one replacing the other. But if the landscape in Ursell’s computer model had barriers, both species could often coexist. Meanwhile, three species locked in a rock-paper-scissors game in an open space could coexist by cycling in and out of dominance. Introducing a barrier into their world often led to one species eliminating the others.

Jim Brau’s Work with the International Linear Collider Featured on Around the O

Learning more about the Higgs boson and finding dark matter are the driving forces for construction of the International Linear Collider, says University of Oregon physicist Jim Brau. Where it will be built may be known soon.

“The linear collider, Brau said, will turn research up a notch. At the Large Hadron Collider, scientists, including a large UO team, have been watching collisions of protons. That led to the discovery of the long-elusive Higgs boson.

Leaders in high-energy physics see this project as being a critical element to advance the science. “It will complement the Large Hadron Collider in Europe.”

At the linear collider, he said, researchers will collide electrons and positrons, providing significant advances in precision to further study the Higgs boson.

Brau is currently associate director of the linear collider collaboration of the International Committee for Future Accelerators.

ESPRIT featured in Around the O

Bryan Rebar, associate director of UO STEM Core, a consortium of UO science, math and education faculty members who supports the center, said the aim is to make the path to science teaching more visible and appealing to science students.

Rebar wants to encourage students studying the sciences to consider a career in the classroom, particularly in disciplines in which teachers are badly needed. Those include subjects like chemistry and physics, which are consistently ranked as the highest-need areas among all academic disciplines.

The ESPRIT program also addresses the issue of K-12 science educators teaching subjects without being fully qualified. Only 47 percent of physics classes are taught by a teacher with a degree in the subject, compared with 73 percent of biology classes and about 80 percent of humanities classes, according to the Physics Teacher Education Coalition.

Toner Recipient of The Lars Onsager Prize

John Toner was frustrated during his final year with IBM in 1993. The industry giant, amid the internet-fueled technological explosion, was giving up fundamental research, his specialty, to pursue applied science to stay competitive.

But a lecture by a visiting researcher, which he almost didn’t attend, reignited this passion and called on his knowledge of fluid mechanics. In his final project at IBM, which he started while considering a job offer from the University of Oregon, he teamed with a young new colleague, Yuhai Tu, to dig deeper into the speaker’s topic.

Within a day, Toner and Tu wrote a short equation that explained how the motion of individual birds in a flock affects the motion of neighboring birds.

That formula has landed Toner, Tu and that day’s speaker, Hungarian scientist Tamás Vicsek, the Lars Onsager Prize from the American Physical Society “for seminal work on the theory of flocking that marked the birth and contributed greatly to the development of the field of active

The Lars Onsager Prize, among 39 prizes announced by the society this fall, has local significance. It was established in 1993 by UO physicist Russ Donnelly, who died in 2015, and his wife Marian in memory of their friend Lars Onsager, a physical chemist and theoretical physicist who won the Nobel Prize in Chemistry in 1968. Two previous winners of the Onsager prize later won Nobel Prizes.

“I had heard from a colleague that when Russ founded this award it was his hope that somebody from the UO would win it,” said Toner, a professor of physics, as he sat in front of a chalkboard filled with equations. “I’m honored to win this award, which is for theoretical statistical physics.”

Alemán lab: Discovery leads to ultrasensitive way to measure light

A team of UO physicists has drummed up a new way of measuring light: using microscopic drums to hear light.

The technology out of the Alemán Lab, known as a “graphene nanomechanical bolometer,” leverages a promising new method and material to detect nearly every color of light at high speeds and high temperatures.

“This tool is the fastest and most sensitive in its class,” said Benjamín Alemán, a professor of physics and a member of the UO’s Center for Optical, Molecular, and Quantum Science and an associate of the Phil and Penny Knight Campus for Accelerating Scientific Impact.

The device offers an alternative to the conventional way of using electricity to measure light, as found in devices like a smartphone’s camera. Instead, this mechanical method captures the vibrations of infinitesimally thin drums that are caused by light. The physicists obtain measurements by listening to the sound of the light absorbed by the drumhead.

The Gravitational-Wave ‘Revolution’ Is Underway,’ Scientific American, Ben Farr, assistant professor, physics

Cast your mind back four years, and gravitational waves were the talk of the town. On September 14, 2015, the first detection of these ripples in space-time was made by the LIGO-Virgo collaboration, revealed months later to deserved global fanfare. Now with the fourth anniversary of that discovery approaching, the field has matured dramatically with dozens of subsequent detections made—and the prospect of even more thrilling discoveries on the horizon.

“It’s hard to overstate how explosive the growth of gravitational-wave astronomy has been,” says Ben Farr of the University of Oregon.
