Nanotube-Based Fabric to Repel Chemical and Biological Agents

Military Fabric to Repel Chemical and Biological Agents

Scientists are working to develop a nanotube-based fabric that repels chemical and biological agents, switching reversibly from a highly breathable state to a protective one in response to the presence of the environmental threat without the need for an external control system. Amherst, Massachusetts – Military uniforms of the future may offer a new layer […]

Ethanol Production Stalls in Brazil

sugar-cane-ethanol-brazil

Brazil experienced a biofuel boom in March 2007, topping out at second in world output behind the USA. The fermentation of sugars produced motor fuel that lowered carbon dioxide emissions, and Brazil became a model for how it was possible to stop relying on fossil fuels. Five years later, biofuels have been criticized and critics […]

Blue Whales Use 360 Degree Body Rolls to Get at Krill

blue-whale-underwater

Blue whales (Balaenoptera musculus) reveal their agile side thanks to video cameras and motion sensors strapped to their bodies. The scientists equipped 22 B. musculus to capture the whales doing underwater pirouettes as they lunge at patches of krill. The scientists published their findings in the journal Biology Letters. The maneuvers, including the pirouette, enables […]

Scientists Discover the Most Powerful Quasar Outflow Ever

Largest Black Hole Blast Discovered

Scientists have discovered a quasar that is at least five times more powerful than any that have been observed to date. Data reveals that a mass of approximately 400 times that of the Sun is streaming away from this quasar per year, moving at a speed of 8000 kilometers per second. Astronomers using ESO’s Very […]

Herschel Finds a Clue to How Planetary Systems Form and Evolve

An expanded diagram of the debris disc and planets around the star known as Gliese 581

In two new studies, scientists use data from the Herschel Space Observatory to find a correlation between the presence of massive debris discs and planetary systems with no Jupiter-class planets, providing a clue to our understanding of how planetary systems form and evolve. Using ESA’s Herschel space observatory, astronomers have discovered vast belts of comets […]

Rising Temperatures & Persistent Drought Threaten to Create a Second Dust Bowl

drought-conditions

Rising temperatures, persistent drought, and depleted aquifers could set the stage for a second Dust Bowl, a period of drought and dust storms that affected the prairies in the USA and Canada during the 1930s. The southern Great Plains have been ravaged, and a cool October broke a 16-month streak of higher than average temperatures […]

Antarctic Lake Vida Has a Bounty of Microbial Life

lake-vida-microbial-life

Lake Vida in Antarctica is covered by an ice cap up to 27 meters thick, is six times saltier than sea water, and with an average temperature of −13 °C is one of the coldest aquatic environments on the planet. However, it is teeming with microbial life. The scientists published their findings in the journal […]

Hunters Kill Yellowstone Park Research Wolves

yellowstone-wolves-killed

Researchers estimate that 10 wolves from Yellowstone National Park have been killed by hunters this month, severely affecting the park’s wolf research programs, one of the longest studies of its kind. The wolves have been tracked since their reintroduction in 1995. The killings came just as the scientists were set to begin the wolf project’s […]

Flexible, Low-voltage Circuits Made from Nanocrystals

Low-voltage Circuits Using Nanocrystals

Scientists at the University of Pennsylvania have shown that nanoscale particles can be “printed” on flexible plastics to form high-performance electronics. PHILADELPHIA — Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications. In a world where electronics are becoming more pervasive, flexibility is a highly desirable […]

High Levels of Anthocyanins Give Black Dahlias Their Color

black-dahlia

There are more than 20,000 varieties of dahlias, including white, yellow, deep reds, and magenta-colored flowers. The rarer black dahlias are especially alluring to horticulturists. A new study explores the reason for its intriguing color. The scientists published their findings in the journal BMC Plant Biology. The Austrian research team collected 14 varieties of black […]

Synthesizing a Flu Vaccine Without the Virus

flu-virion

A new vaccine strategy, which uses synthetic messenger RNA (mRNA) instead of proteins purified from viruses, could make flu shots cheaper, safer, and easier to produce. German scientists have shown that they have been able to protect mice, ferrets, and pigs against influenza. The scientists published their findings in the journal Nature Biotechnology. Most flu […]

LHC Collisions May Have Yielded a New Type of Matter

data from the Large Hadron Collider suggest the collisions may be producing a new type of matter

A team of scientists working at the Large Hadron Collider found that in a sample of 2 million lead-proton collisions, some pairs of particles flew away from each other with their respective directions correlated, suggesting that the collisions may have produced a new type of matter known as color-glass condensate. Collisions between protons and lead […]
