Cement's basic molecular structure finally decoded : Robustness comes from messiness, not a clean geometric arrangement

Location: Cambridge, United States

In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and...

NanoPen: Dynamic, Low-Power, and Light-Actuated Patterning of Nanoparticles

Location: California, United States

Abstract:

The ability to pattern nanostructures has important applications in medical diagnosis,(1, 2) sensing,

Robots swim with the fishes : New robots mimic fish's swimming, could be used in underwater exploration

Location: Cambridge, United States

Borrowing from Mother Nature, a team of MIT researchers has built a school of swimming robo-fish that slip through the water just as gracefully as the real thing, if not quite as fast.

Mechanical engineers Kamal Youcef-Toumi and Pablo...

A genetic study reveals the diversity and origins of African populations

Location: Maryland, United States

By analyzing the genetic differences between more than 3 000 people across Africa and from other parts of the world, researchers have shown how the current African populations had evolved from 14 aboriginal groups. The result of their...

More-Precise Genetic Engineering for Plants

Location: Minnesota, United States

Genetically engineering plants is a time-intensive process. Methods currently used to deliver genetic changes are imprecise, so it's often necessary to generate thousands of plants to find one that happens to have the desired alteration....

Chemists Create Bipedal, Autonomous DNA Walker

Location: New York, United States

Chemists at New York University and Harvard University have created a bipedal, autonomous DNA "walker" that can mimic a cell's transportation system. The device, which marks a step toward more complex synthetic molecular motor systems, is...

Human Heart Grows New Cells

Location: Stockholm, Sweden

The human heart has a notorious reputation for being unable to heal itself, but new research suggests it is capable of at least some self-repair. Using carbon dating to gauge the age of heart cells, scientists have found that low numbers...

New Possibilities for Hydrogen-Producing Algae

Location: Carnegie, United States

The single-celled green alga Chlamydomonas reinhardtii generates hydrogen by fermentation under low oxygen conditions. Cells in photo are stained with fluorescent dyes. Purple indicates DNA, green indicates flagella.

Brain Images Reveal the Secret to Higher IQ

Location: Los Angeles, United States

New research suggests that the layer of insulation coating neural wiring in the brain plays a critical role in determining intelligence. In addition, the quality of this insulation appears to be largely genetically determined, providing...

Nanofibers Power Attoscale Chemistry: A new way to perform experiments using just thousands of molecules.

Location: Ohio, United States

Researchers have developed a new way to perform chemical reactions involving only about 1,000 molecules. The method could prove useful in the rapid screening of chemical reactions when searching for new drugs and industrial materials.

DNA evidence is in, newly discovered species of fish dubbed H. psychedelica

Location: washington, United States

DNA evidence is in, newly discovered species of fish dubbed H. psychedelica-A juvenile H. psychedelica hops along a coral reef, its course even more precarious as it is buffeted by currents. Notice how it curves its tail around to...

A New era of Cancer

Location: Stockholm, Sweden

Every year, millions of people are diagnosed with cancer - a remarkably high number. But what about the flipside of those statistics? That is, two out of three people never get cancer, and more than half of heavy smokers don’t get...

Researchers Control The Assembly Of Nanobristles Into Helical Clusters

Location: Harvard, United States

From the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as abundant as they are useful in nature and manufacturing alike. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered...

The mechanisms of heredity reveal their secrets

Location: Paris, France

One of the first steps of memory transmission from one cell to its descendants, or how a cell transmits its functions and characters when it divides, has been described by Dr. Christian Bronner, researcher in-Institut Gilbert Laustriat...

Researchers Unveiled the Activity of a Specific Family of Nanometer-Sized Molecular Motors

Location: University of Pennsylvania School of Medicine, United States

Researchers at the University of Pennsylvania School of Medicine discovered that the activity of a specific family of nanometer-sized molecular motors called myosin-I...

Researchers Identify that RNA can Interact with a Non-Gene Region of DNA called a Promoter Region

Location: UT Southwestern Medical Center, United States

Tiny strands of genetic material called RNA – a chemical cousin of DNA – are emerging as major players in gene regulation, the process inside cells that drives all biology and that scientists seek to control in order to fight disease....

Researchers Demonstrated Basic Building Blocks for Distributed Quantum Computing Using Entangled Photons

Location: Center for Photonic Communication and Computing, United States

For now, full-fledged quantum computers are the stuff of science fiction — in last summer's blockbuster movie Transformers, the bad guys use quantum computing to break into the

Searching for Evidence of Life on Mars or Other Planets New Research Finds Cellulose Microfibers

Location: University of North Carolina at Chapel Hill, United States

Looking for evidence of life on Mars or other planets? Finding cellulose microfibers would be the next best thing to a close encounter, according to new research from the ...

Arizona Researcher Developed Biosensing Nanodevice that can Revolutionize Health Screenings

Location: Arizona State University, United States

One day soon a biosensing nanodevice developed by Arizona State University researcher Wayne Frasch may eliminate long lines at airport security checkpoints...

Using New Technique Purdue University Researchers Take a Big Step in Examination of Small Structures

Location: Purdue University, United States

A team led by a Purdue University researcher has achieved images of a virus in detail two times greater than had previously been achieved.
