From vitro to vivo: Fully automated design of synthetic RNA circuits in living cells
New microscope collects dynamic images of the molecules that animate life
Over the last decade, powerful new microscopes have dramatically sharpened biologists' focus on the molecules that animate and propel life. Now, a new imaging platform developed by Eric Betzig and colleagues ...
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
Nanomotors are controlled, for the first time, inside living cells (w/ video)
For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. ...
Engineering team designs 'living materials'
Inspired by natural materials such as bone—a matrix of minerals and other substances, including living cells—MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving ...
New live-cell printing technology works like ancient Chinese woodblocking
With a nod to 3rd century Chinese woodblock printing and children's rubber stamp toys, researchers in Houston have developed a way to print living cells onto any surface, in virtually any shape. Unlike recent, ...
Scientists say NASA's 'new arsenic form of life' was untrue
Two new scientific papers have disproved a controversial claim made by NASA-funded scientists in 2010 that a new form of bacterial life had been discovered that could thrive on arsenic.
Diamond 'flaws' pave way for nanoscale MRI
Breakthrough offers high-sensitivity nanoscale sensors, and could lead to magnetic imaging of neuron activity and thermometry on a single living cell.
Chemists show life on Earth was not a fluke
How life came about from inanimate sets of chemicals is still a mystery. While we may never be certain which chemicals existed on prebiotic Earth, we can study the biomolecules we have today to give us clues ...
Cadherin-catenin-actin structure exerts force inside and between cells in living tissues, study shows
If you place certain types of living cells on a microscope slide, the cells will inch across the glass, find their neighbors, and assemble themselves into a simple, if primitive tissue. A new study at Stanford ...
Hong Kong researchers store data in bacteria
The US' national archives occupy more than 500 miles (800 kilometres) of shelving; France's archives stretch for more than 100 miles of shelves, as do Britain's.
Earth's oldest fossils boost hopes for life on Mars
(PhysOrg.com) -- Microfossils found in Australia show that more than 3.4 billion years ago, bacteria thrived on an Earth that had no oxygen, a finding that boosts hopes life has existed on Mars, a study published ...
An unlikely use for diamonds
Tiny diamonds are providing scientists with new possibilities for accurate measurements of processes inside living cells with potential to improve drug delivery and cancer therapeutics.
Cell membranes self-assemble
A self-driven reaction can assemble phospholipid membranes like those that enclose cells, a team of chemists at the University of California, San Diego, reports in Angewandte Chemie.
