NASA’s Spitzer Sees the Light of Alien ‘Super Earth’

PASADENA, Calif. – NASA’s Spitzer Space Telescope has detected light emanating from a “super-Earth” planet beyond our solar system for the first time. While the planet is not habitable, the detection is a historic step toward the eventual search for signs of life on other planets.

“Spitzer has amazed us yet again,” said Bill Danchi, Spitzer program scientist at NASA Headquarters in Washington. “The spacecraft is pioneering the study of atmospheres of distant planets and paving the way for NASA’s upcoming James Webb Space Telescope to apply a similar technique on potentially habitable planets.” (more…)

Biologists Turn Back the Clock to Understand Evolution of Sex Differences

Battles of sexes shown to spur adaptive sex differences

Sex differences account for some of the most of the spectacular traits in nature: the wild colours of male guppies, the plumage of peacocks, tusks on walruses and antlers on moose. Sexual conflict – the battle between males and females over mating – is thought to be a particularly potent force in driving the evolution of traits that differ in males and females.

However, the genetic processes responsible for producing such traits are not well understood, nor how they evolved from their simpler less elaborate ancestral forms. We tend to assume that each tiny step in evolution is an advantage. But are they really? (more…)

Happiness Model Developed by MU Researcher Could Help People Go From Good to Great

COLUMBIA, Mo. — The sayings “variety is the spice of life” and “happiness isn’t getting what you want, but wanting what you get” seem to have a psychological basis, according to a new study by an MU psychologist who identified two keys to becoming happier and staying that way.

“Although the Declaration of Independence upholds the right to pursue happiness, that search can be a never-ending quest,” said Kennon Sheldon, professor of psychological sciences in the College of Arts and Sciences. “Previous research shows that an individual’s happiness can increase after major life changes, such as starting a new romantic relationship, but over time happiness tends to return to a previous level. Through our research, we developed a model to help people maintain higher levels of happiness derived from beneficial changes. The model consists of two major components: the need to keep having new and positive life-changing experiences and the need to keep appreciating what you already have and not want more too soon.” (more…)

UD alum and ‘Jeopardy!’ champ Craig tells students it’s important to take chances

When Li Liao, associate professor in the University of Delaware Department of Computer and Information Sciences, saw Roger Craig’s almost-perfect GRE score while Craig was applying to graduate school at UD, the faculty member said to himself, “Wow, this guy is smart.”

Liao says he took a chance on Craig, who had no formal training in computer science. Craig would go on to exceed his adviser’s expectations, studying bioinformatics and earning master’s and doctoral degrees in computer and information sciences at UD.

Craig also would set several records on the Jeopardy! quiz show in 2010 and 2011, among them, the all-time record for single-day winnings ($77,000). Craig said that when he hit the daily doubles, he almost always bet everything. (more…)

Researchers Find Potential ‘Dark Side’ To Diets High In Beta-Carotene

COLUMBUS, Ohio – New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene.

This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient.

But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the body: They actually block some actions of vitamin A, which is critical to human vision, bone and skin health, metabolism and immune function. (more…)
