Size, personality matter in how Kalahari social spiders perform tasks
At first glance, colonies of thousands of social spiders all look the same and are busy with the same tasks. Not so, say researchers Carl Keiser and Devin Jones, after carefully studying various gatherings of a social spiders of the Kalahari Desert in South Africa. The size and condition of a particular spider's body indicates which task it generally performs within a colony. The study is published in Springer's journal Behavioral Ecology and Sociobiology.

Students to hack hardware, software and data to build security skills
Students at Case Western Reserve University and Cleveland State University will begin hacking computers -- for credit -- this fall. The universities are offering undergraduates a series of three classes that focus on hacking and learning to protect hardware, software and data from cyber attacks. The classes were developed and will be supported with help of a NSF grant.

Study finds forest corridors help plants disperse their seeds
A forest, a supercomputer and some glow-in-the-dark yarn have helped a team of field ecologists conclude that woodland corridors connecting patches of endangered plants not only increase seed dispersal from one patch to another, but also create wind conditions that can spread the seeds for much longer distances. Gil Bohrer, Ph.D., an environmental engineer at Ohio State University, leveraged Ohio Supercomputer Center systems to simulate a forest and the winds that flow through it.

Bighorn sheep went extinct on desert island in Gulf of California, study finds
Using ancient DNA analysis and other techniques, a research team led by conservation biologists at the University of California, Riverside has determined that bighorn sheep, so named for their massive spiral horns, became extinct on Tiburon Island, a large and mostly uninhabited island just off Sonora, Mexico, in the Gulf of California, sometime in the last millennium -- specifically between the 6th and 19th centuries.

New airborne GPS technology for weather conditions takes flight
A new technique led by a researcher at Scripps Institution of Oceanography at UC San Diego stands to improve weather models and hurricane forecasting by detecting precise conditions in the atmosphere through a new GPS system aboard airplanes. The first demonstration of the technique, detailed in the journal Geophysical Research Letters, is pushing the project's leaders toward a goal of broadly implementing the technology in the near future on commercial aircraft.

New statistical models could lead to better predictions of ocean patterns
The world's oceans cover more than 72 percent of the earth's surface, impact a major part of the carbon cycle, and contribute to variability in global climate and weather patterns. Now, researchers at the University of Missouri applied complex statistical models to increase the accuracy of ocean forecasting that influences the ways in which forecasters predict long-range events such as El Nińo and the lower levels of the ocean food chain.

Simulations predict blast scenarios, have crossover animation appeal in Disney's 'Frozen'
Simulation-based engineering science allows researchers to predict the effects of building explosions and analyze the response of building materials to those threats. Using a $400,000, five-year CAREER grant from the National Science Foundation, researchers at the University of Missouri developed the Material Point Method, a computer-generated tool that not only creates blast scenarios that informs blast and impact resistant materials and design, but also is crossing over into Hollywood animation -- most recently, Disney's Oscar-winning animated film, 'Frozen.'

A new study by University of Pennsylvania researchers shows that Azara's owl monkeys (Aotus azarae) are unusually faithful. The investigation of 35 offspring born to 17 owl monkey pairs turned up no evidence of cheating; the male and female monkeys that cared for the young were the infants' true biological parents.

First direct evidence of cosmic inflation
Researchers from the BICEP2 collaboration today announced the first direct evidence for cosmic inflation. Their data also represent the first images of gravitational waves, or ripples in space-time. These waves have been described as the 'first tremors of the Big Bang.' Finally, the data confirm a deep connection between quantum mechanics and general relativity.

Rocky Mountain wildflower season lengthens by more than a month
A 39-year study of wildflower blooms in a Rocky Mountain meadow shows more than two-thirds of alpine flowers changed their blooming pattern in response to climate change. Half are beginning to bloom weeks earlier, more than a third are reaching peak bloom earlier, and others' last blooms are later. Records of more than two million blooms show flowering plants' response to climate change is more complex than previously believed. Species that depend on wildflowers are likely to be affected.
