Many religious people view science favorably, but reject certain scientific theories
A new study finds that many US adults -- roughly one in five -- are deeply religious, know a lot about science, and support many practical uses of science and technology in everyday life, but reject scientific explanations of creation and evolution.

Damaged DNA may stall patrolling molecule to initiate repair
Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself may be the key that allows the protein molecule to find its target, according to researchers at the University of Illinois at Chicago.

Long series of droughts doomed Mexican city 1,000 years ago
The former city and now archaeological site called Cantona in the highlands east of Mexico City appears to have been abandoned nearly 1,000 years ago as a result of a prolonged dry spell that lasted about 650 years, according to a new study by UC Berkeley geographers. The dry period, characterized by a long series of droughts, occurred during a nearly 2,000-year-long period of increasing aridity throughout Mesoamerica that impacted other civilizations, including Teotihuacan.

Chimps with higher-ranking moms do better in fights
For chimpanzees, just like humans, teasing, taunting and bullying are familiar parts of playground politics. An analysis of twelve years of observations of playground fights between young chimpanzees in East Africa finds that chimps with higher-ranked moms are more likely to win.

Playing with puzzles and blocks may build children's spatial skills
Play may seem like fun and games, but new research shows that specific kinds of play are actually associated with development of particular cognitive skills. Data from a nationally representative study show that children who play frequently with puzzles, blocks, and board games tend to have better spatial reasoning ability. The research is published in Psychological Science, a journal of the Association for Psychological Science.

Mobile apps take students into the laboratory
Mobile apps have proved to be valuable educational tools, but laboratory instructors thus far have been limited to using mobile devices only for virtual laboratories with simulated experiments. Now, researchers have developed a series of mobile applications that allow students to remotely interact with real data and equipment in real laboratories. Students reported deeper engagement levels using mobile apps and the virtual lab.

Custom tailoring robotic exoskeletons that fit to perfection
Researchers are developing a design framework that will help speed the design of powered exoskeletons for the lower body. The modeling will enable highly customized exoskeletons that give disabled persons natural motion with better comfort and safety. The devices will also allow military personnel and construction workers to carry heavy loads over long distances.

Customized soap bubbles set to transform drug and vaccine delivery
At a University of Maryland start-up called SD Nanosciences, scientists are covering soap bubbles with biomolecules that act as a disguise, tricking the body's cells into mistaking the capsule for a bacterium, a cancer cell or almost any other disease-causing cell. Because the technology is flexible, cost-effective and highly efficient, it is drawing a lot of attention from both public and private funders for drug delivery and vaccine production.

Anthropology: Ancient skull from Galilee cave offers clues to the first modern Europeans
The discovery of a 55,000-year-old skull in Northern Israel provides new insights into the migration of modern humans. The skull has a bun-shaped region at the back resembling modern African and European skulls, suggesting the people of this area could be closely related to the first modern humans that colonized Europe. It also indicates that modern humans and Neanderthals inhabited the southern Levant close in time to the two groups' likely interbreeding event.

National Science Review
Chinese and American scientists review early evolution of eukaryotic multicellularity
The rise of multicellularity represents a major evolutionary transition and it occurred independently in multiple eukaryote clades. Complex multicellular eukaryotes began diversifying in the Ediacaran Period, just before the Cambrian explosion. The Ediacaran fossil record can provide key paleontological evidence about the early radiation of multicellular eukaryotes. In a new study, Chinese and American scientists review exceptionally preserved eukaryote fossils from the Ediacaran Weng'an biota in South China, along with varying interpretations of these fossils.

Scientists in China and US chart latest discoveries of iron-based superconductors
In a superconductor electricity is transported without loss of energy at extremely low temperatures. Recently discovered iron-based superconductors have the highest superconducting transition temperature next to copper oxides. In a recent paper, scientists based in China and the US review material aspects and physical properties of iron-based superconductors. They outline the transition temperature's dependence on the crystal structure, the interplay between antiferromagnetism and superconductivity, and the electronic properties of compounds obtained by angle-resolved photoemission spectroscopy.

Quantum computer as detector shows space is not squeezed
Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions -- that it's not squeezed in one direction relative to another. A new experiment by UC Berkeley physicists used partially entangled atoms -- identical to the qubits in a quantum computer -- to demonstrate more precisely than ever before that this is true: to one part in a billion billion.

Researchers use sound to slow down, speed up, and block light
Researchers from the University of Illinois at Urbana-Champaign have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed. This non-reciprocal behavior is essential for building isolators and circulators.

New mechanism unlocked for evolution of green fluorescent protein
A primary challenge in the biosciences is to understand the way major evolutionary changes in nature are accomplished. Sometimes the route turns out to be very simple. An example of such simplicity is provided in a new publication by a group of ASU scientists. They show, for the first time, that a hinge migration mechanism, driven solely by long-range dynamic motions, can be the key for evolution of a green-to-red photoconvertible phenotype in a green fluorescent protein.

Penn research shows relationship critical for how cells ingest matter
To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the material in a bubble called a vesicle. Researchers from the University of Pennsylvania have now revealed a relationship that governs this process, known as endocytosis.
