Rejected internal job applicants are twice as likely to quit
Internal job applicants who face rejection are nearly twice as likely to leave their organizations than those who were either hired for an internal job or had not applied for a new job at all, ILR School research finds.

Images that fool computer vision raise security concerns
Computers are learning to recognize objects with near-human ability. But Cornell researchers have found that computers, like humans, can be fooled by optical illusions, which raises security concerns.

Nearly a third of TV ads play to empty rooms
Jura Liaukonyte, associate professor at Dyson, and colleagues tracked ad viewership using tools that, instead of just monitoring the television, measured actual viewer presence in the room, and focal attention on the screen.

Fewer than 40% of New Yorkers earn a living wage
The Cornell ILR Wage Atlas shows who in New York state earns living wages and where, helping policymakers and other stakeholders to understand patterns of inequality.

Possible Radio Emission from Exoplanet Detected
By using a radio telescope array, a Cornell postdoc and an international team of scientists may have detected emissions from a planet beyond our own solar system.
11
A lifetime of social ties adds up to healthy aging
Research shows the biological aging process can be slowed by strong social connections and support.
12
'Zeno effect' verified: Atoms won't move while you watch
Researchers observed a mass of atoms cooled almost to absolute zero so that they could "tunnel" from place to place. But as long as the observation continued, no tunneling occurred.

Soil bacteria could improve crop yields, via fungi
The findings from Boyce Thompson Institute researchers could point the way to cost-effective, eco-friendly ways of enriching soil and reducing reliance on conventional fertilizers.
15
Texas power crisis revealed flaw in market’s design
New research finds decentralized electricity markets are prone to underinvestment in resilience to rare events like the severe winter storms that crippled the Texas grid a year ago.
16
Engineers create ‘lifelike’ material with artificial metabolism
Cornell engineers have constructed a DNA material with capabilities of metabolism, in addition to self-assembly and organization – three key traits of life.

Food coloring, anti-caking nanoparticles may affect human gut
Metal oxide nanoparticles – commonly used as food coloring and anti-caking agents in commercial ingredients – may damage parts of the human intestine, say Cornell and Binghamton University scientists.
19
Policy, not tech, spurred Danish dominance in wind energy
An analysis of Denmark’s wind industry offers lessons for policymakers seeking to increase renewable electricity production with limited budgets, according to Cynthia Lin Lawell.

Hiding secret codes in light protects against fake videos
A team of Cornell computer science researchers has developed a way to “watermark” light in videos, which they can use to detect if video is fake or has been manipulated, another potential tool in the fight against misinformation.

People are biased against creative ideas, studies find
While people say they welcome creative ideas, they are in fact frightened by them and favor the tried and true, according to a new ILR School study. (Aug. 25, 2011)
22
Smart thermostats inadvertently strain electric power grids
Smart thermostats may be falling into a dumb trap. While these devices save homeowners money, Cornell engineers found they may be prompting unintentional energy spikes on the grid.
23
Women preferred 2:1 over men for STEM faculty positions
A new study by Cornell psychologists suggests that science and engineering faculty preferred women two-to-one over identically qualified male candidates for assistant professor positions.
24
Face-to-face interaction enhances learning, innovation
Faces transmit social information about goals and motivations that can help learners overcome the inherent difficulty of sharing a teacher's visual perspective, new Cornell psychology research finds.

Butterfly wing patterns emerge from ancient ‘junk’ DNA
Butterfly wing patterns have a basic plan to them, which is manipulated by non-coding regulatory DNA to create the diversity of wings seen in different species, according to new research.

Red algae proteins grafted into tobacco double plant growth
Cornell researchers have successfully transferred key regions of a highly efficient red algae into a tobacco plant to dramatically improve plant productivity and increase carbon sequestration.
28
Researchers identify new type of superconductor
The history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, Cornell researchers have discovered a possible third type: g-wave.

U.S. could feed 800 million people with grain that livestock eat, Cornell ecologist advises animal scientists
From one ecologist's perspective, the American system of farming grain-fed livestock consumes resources far out of proportion to the yield, accelerates soil erosion, affects world food supply and will be changing in the future.
