Mar. 13, 2013: BIOFAB researchers have produced high quality standardized public domain DNA sequences for genetic engineering. Predictability is often used synonymously with "boring," as in that story or that outcome was soooo predictable. For practioners of synthetic biology seeking to engineer valuable new microbes, however, predictability is the brass ring that must be captured. Researchers with the multi-institutional partnership known as BIOFAB have become the first to grab at least a portion of this ring by unveiling a package of public domain DNA sequences and statistical models that greatly increase the reliability and precision by which biological systems can be engineered.

Mar. 14, 2013: This picture shows a bullfrog and songbird removed from its stomach. American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems. In the largest study of its kind to date, the stomach contents of over 5,000 invasive alien American bullfrogs from 60 lakes and ponds on southern Vancouver Island were examined to identify the native and exotic animals that they had preyed upon.

Mar. 20, 2013: Splenium of the Corpus Callosum: This is a white matter fiber bundle that supports visual orienting in typically developing infants and may be implicated in the early development of autism spectrum disorders. Infants at 7 months of age who go on to develop autism are slower to reorient their gaze and attention from one object to another when compared to 7-month-olds who do not develop autism, and this behavioral pattern is in part explained by atypical brain circuits.

Mar. 19, 2013: This image show a close up of Cystomastacoides kiddo, named after Beatrix Kiddo, a protagonist from Tarantino's "Kill Bill." Parasitoid wasps of the family Braconidae are known for their deadly reproductive habits. Most of the representatives of this group have their eggs developing in other insects and their larvae, eventually killing the respective host, or in some cases immobilizing it or causing its sterility. Three new species of the parasitoid wasp genus Cystomastacoides, recently described in the Journal of Hymenoptera Research, reflect this fatal behavior.

The mixture may have been used as a paint or adhesive. It's the oldest evidence of humans making a complex compound, and even the oldest evidence of humans using containers


The Eye

This image shows the smallest cones at the center of the retina, (the fovea). Whenever we direct our gaze at something, for example to read, the image of what we are looking at is formed over these very important cones. The magnification shows a more eccentric retinal location, in which the large bright dots with a dark ring around them are cones, and the surrounding (and far more abundant) smaller spots are rods.

An artist's depiction of a mother and juvenile plesiosaur as they may have looked swimming in the waters of the Southern Ocean roughly 70 million years ago.

The well-preserved fossil skeleton of a juvenile plesiosaur--a marine reptile--was recovered by an American-Argentine research team in Antarctica. The fossil remains represent one of the most-complete plesiosaur skeletons ever found and is thought to be the best-articulated fossil skeleton ever recovered from Antarctica. The creature would have inhabited Antarctic waters during a period when the Earth and oceans were far warmer than they are today.

A red fluorescent variety of staghorn coral (Acropora millepora). In a National Science Foundation-supported study, researchers found that the ability to fluoresce may influence whether or not the coral settle on the reef of their origin or disperse, and go elsewhere.

Staghorn coral (Acropora millepora) were the focus of a National Science Foundation (NSF)-supported study by Misha Matz, an assistant professor of integrative biology at the University of Texas at Austin, and colleagues, to address coral reef connectivity, genetics of physiology and life history traits, and their evolutionary modifications in response to ongoing climate change.

"Engine-driven" supernova explosion, with accretion disk and high-velocity jets. This is the first time astronomers have found a supernova explosion with properties similiar to a gamma-ray burst, but without seeing any gamma rays from it.

Scientists expect the discovery--made using the National Science Foundation's Very Large Array (VLA) radio telescope--will point the way toward locating many more examples of these mysterious explosions. Radio observations will be a more powerful tool for discovering these kind of supernova in the universe than gamma-ray satellites.

Cattleheart Butterfly

The Amazonian butterfly emerald-patched cattleheart. Researchers from Yale University, supported by the National Science Foundation, are studying the properties of the colors of butterfly wings. Using an X-ray scattering technique, they were able to determine the 3-D internal structure of the scales on the wings of several species of butterflies.

Scientists from the University of Groningen in The Netherlands successfully used a 'genome mining' approach to find and activate a group of genes in the bacterium Streptomyces coelicolor. This resulted in the production of a novel antibiotic, seen here, that could lead to new treatments for serious diseases that are rapidly acquiring multi-drug resistance.

How Stem Cells Work

Within 24 hours of culturing adult human stem cells on a new type of matrix, University of Michigan researchers were able to make predictions about how the cells would differentiate, or what type of tissue they would become. "We show, for the first time, that we can predict stem cell differentiation as early as Day 1," said Jianping Fu, an assistant professor in mechanical and biomedical engineering.

Sequential still frames from a video filmed at 10,000 fps show a mushroom cloud of sphagnum spores with a "trailing wake" clearly visible. The spores don't move quickly, and are carried by turbulent wind currents to establish colonies many kilometers away. However, spores that are easily kept aloft are also rapidly decelerated in still air; thus, dispersal range depends strongly on release height.

Saturn's Heartbeat

Saturn's aurora, an ethereal ultraviolet glow which illuminates Saturn's upper atmosphere near the poles, pulses roughly once per Saturnian day, space researchers discovered. The length of a day has been under much discussion since it was discovered that the traditional "clock" used to measure the rotation period of Saturn, a gas giant planet with no solid surface for reference, apparently does not keep good time.

Tougher than a bullet-proof vest yet synonymous with beauty and luxury, silks spun by worms and spiders are a masterpiece of nature hard to replicated in the lab. Tufts University engineers recently built this silk card, which shows diffractive optics entirely constituted by pure silk obtained by pouring silk solution on patterned molds and letting the solution dry and crystallize. The resulting film retains the pattern and is a free-standing optical component so flexible it can be rolled up.

Common household products like detergents and shampoo contain surfactants -- organic compounds that act as detergents. By simulating them on a supercomputer, researchers wash away expensive and slow laboratory work as they design new products.

Prostate Cancer's Origin?

A disease's origin doesn't explain the whole story, scientists explained recently. "Luminal" cells are believed to be the origin for prostate cancer, for example, because the disease is characterized by their expansion and the absence of "basal" cells -- the green cells here lining the outside of benign prostate glands. Yet scientists recently found found that basal cells can cause prostate cancer too, proof that histology doesn't always correlate with cellular origins.
