Decade of data shows FEMA flood maps missed 3 in 4 claims
An analysis of flood claims in three Houston suburbs from 1999-2009 found that the Federal Emergency Management Agency's 100-year flood plain maps failed to capture 75 percent of flood damages from five serious floods, none of which reached the threshold rainfall of a 100-year event.

Penn: How openings in Antarctic sea ice affect worldwide climate
In a new analysis of climate models, researchers from the University of Pennslyvania, Spain's Institute of Marine Sciences and Johns Hopkins University reveal the significant global effects that seemingly anomalous polynyas, or openings in sea ice, can have. Their findings indicate that heat escaping from the ocean through these openings impacts sea and atmospheric temperatures and wind patterns around the globe and even rainfall around the tropics.

Scientists track the brain-skull transition from dinosaurs to birds
The dramatic, dinosaur-to-bird transition that occurred in reptiles millions of years ago was accompanied by profound changes in the skull roof of those animals -- and holds important clues about the way the skull forms in response to changes in the brain -- according to a new study. It is the first time scientists have tracked the link between the brain's development and the roofing bones of the skull.

Scientists to study health of plant-bacteria symbiosis in California
Scientists at the UC Riverside and Oregon State University have received a grant to study the health and sustainability of critical symbioses between plants and bacteria across California. Symbiotic bacteria in soils transform how plants interact with their environment. But the symbioses vary greatly in their effects on plant health and fitness. Little is understood about the forces that sustain this variation and drive the spread of symbionts that interact yet fail to benefit plants.

Why it's difficult to predict evolutionary fate of a new trait
In a new review paper, scientists explain the vexing complexities that make it hard to predict whether a new genetic trait will take over a population or die out, a key challenge for many fields including infectious disease.

How tails help geckos and other vertebrates make great strides
A wagging tail is often associated with dogs' emotions, but the side-to-side motion may also help them take longer strides and move faster, according to a study by researchers at the University of California, Riverside. The research was done on leopard geckos, which are ideal animals for the study of tail function because they naturally lose their tails as a defense mechanism against predators in a process called autotomy.

UT Austin study raises question: Why are fossilized hairs so rare?
New research led by The University of Texas at Austin has found that when it comes to preserving body parts, fossilized hair is rare--five times rarer than feathers--despite being an important tool for understanding ancient species. This finding has researchers trying to determine if the lack of hair in the fossil record has to do with physical traits that might make it more difficult for hair to fossilize, or an issue with scientists' collection techniques that could lead to them missing important finds.

The doubly magic nucleus of lead-208 -- it spins, though it shouldn't!
We imagine atomic nuclei to be more or less spherical, chaotic clusters of protons and neutrons. Experiments at the Argonne National Laboratory, inspired by physicists from the Institute of Nuclear Physics of the PAS, are verifying these ideas. Using an astronomical analogy we can say that the majority of nuclei are similar in outline to rocky moons or asteroids of different shapes, but nuclei of lead-208 can resemble planet surrounded by a dense atmosphere.

Sometimes you shouldn't say sorry
Being socially rejected can be a painful emotional experience -- but being told sorry may not soften the blow, finds a new study published in Frontiers in Psychology. Contrary to popular belief, apologies increase hurt feelings and the need to express forgiveness, but do not increase feelings of forgiveness, for the person being rebuffed.

Neuroscientists explore the risky business of self-preservation
Northwestern University researchers have learned that the escape response for prey is more nuanced than previously thought. In a study of larval zebrafish, the researchers are the first to find that the animal's innate escape response incorporates the speed of the approaching predator -- not just the proximity of the predator -- in its calculation of how best to flee. The new information can help scientists understand the neural mechanics that fuel the most elemental self-preservation instincts.

Streamlined security: Optimizing sensor placement with mathematics
Increasing reliance on heightened security in public and private settings calls for optimal sensor technology. However, placing security sensors to optimize resource management and system performance while simultaneously protecting people and products is undoubtedly challenging. In a paper publishing in the SIAM Journal on Scientific Computing, Sung Ha Kang, Seong Jun Kim, and Haomin Zhou propose a computational level set method to optimally position a sensor-based security system for maximum surveillance of a complex environment.

A bioactive molecule may protect against congestive heart failure after heart attacks
