Life as we know it has certain properties that are consistent regardless whether you’re looking at a bacterial colony in a petri dish or a primate colony in South America. Rick Michod, UA professor and department head of ecology and evolutionary biology, has received $1.3 million from NASA to investigate what properties of biology define an individual organism.

Many things in life are not fair. But some things are at least consistent.

For example, all life as we know it has certain universal properties, which presumably define how life would be organized anywhere it evolved in the universe, said Richard Michod, professor and head of the department of ecology and evolutionary biology at the University of Arizona. (more…)

‘Sweet Dreams (Are Made of Chemistry)’

Professor Neil Garg’s students turn organic chemistry reactions into song

When Eurythmics recorded their hit song “Sweet Dreams (Are Made of This)” in 1983, they somehow neglected to include chemical equations. Thirty years later, UCLA undergraduates Jessica Lee, Emily Chuang and Christine Nguyen have corrected the omission.

Older males make better fathers says new research on beetles

Researchers at the University of Exeter found that older male burying beetles make better fathers than their younger counterparts.

The study found that mature males, who had little chance of reproducing again, invested more effort in both mating and in parental care than younger males.

The study, published in the journal Proceedings of the Royal Society of London – B, considered how the likelihood of paternity influenced the way that males cared for young. Older males were good fathers and looked after the young even when they were unsure whether the offspring were theirs. Younger males, who had a higher chance of reproducing again, tended to care less for offspring, particularly when they were uncertain of their paternity. (more…)

Step into an anechoic chamber where sounds go to die

Microsoft’s new film series “On the Whiteboard” explores topics at the intersection of technology and culture, and introduces people, places and things behind the products.

REDMOND, WASH. – June 24, 2013 – In the second episode of Microsoft’s new film series “On the Whiteboard,” Editor Pamela Woon exposes an anechoic chamber of secrets. It’s an isolated space where you can actually hear blood pumping through your veins – because in here, there’s no echo. In this heavily padded room built on top of springs, sounds don’t bounce back, they’re absorbed. (But your body might, since you’re walking on springs.)

Researchers study the sounds of silence here, including testing and analyzing Surface to make sure that click you hear when you snap the kickstand shut is pleasing and robust to the average ear. (more…)

Researchers Find Genetic Diversity Key to Survival of Honey Bee Colonies

When it comes to honey bees, more mates is better. A new study from North Carolina State University, the University of Maryland and the U.S. Department of Agriculture (USDA) shows that genetic diversity is key to survival in honey bee colonies – a colony is less likely to survive if its queen has had a limited number of mates.

“We wanted to determine whether a colony’s genetic diversity has an impact on its survival, and what that impact may be,” says Dr. David Tarpy, an associate professor of entomology at North Carolina State University and lead author of a paper describing the study. “We knew genetic diversity affected survival under controlled conditions, but wanted to see if it held true in the real world. And, if so, how much diversity is needed to significantly improve a colony’s odds of surviving.” (more…)

Researchers take new look at future Colorado River flows

The Colorado River provides water for more than 30 million people in the U.S. West, so water managers have been eager to understand how climate change will affect the river’s flow. But scientific studies have produced an unsettling range of estimates, from a modest decrease of 6 percent by 2050 to a steep drop of 45 percent by then. (more…)

UW research: World population could be nearly 11 billion by 2100

A new statistical analysis shows the world population could reach nearly 11 billion by the end of the century, according to a United Nations report issued June 13. That’s about 800 million, or about 8 percent, more than the previous projection of 10.1 billion, issued in 2011.

The projected rise is mostly due to fertility in Africa, where the U.N. had expected birth rates to decline more quickly than they have.

“The fertility decline in Africa has slowed down or stalled to a larger extent than we previously predicted, and as a result the African population will go up,” said Adrian Raftery, a University of Washington professor of statistics and of sociology. (more…)

Microsoft delivers on its enterprise social vision with accelerating user, customer and engagement growth.

REDMOND, Wash. — June 25, 2013 — Today marks one year since Microsoft Corp. announced its acquisition of Yammer, the leading provider of enterprise social networks. Since the acquisition, Microsoft’s enterprise social momentum has accelerated in all areas, including new users, paid customers, user engagement, innovation, and the ecosystem of partners selling and connecting to the Yammer platform.

Twelve-month growth highlights include the following:

Registered users have grown by more than 55 percent to nearly 8 million.
Paid networks increased more than 200 percent year over year.
Yammer user activity (i.e., messages, groups and files) has approximately doubled year over year. (more…)
