Last Week's Best—Quantum mechanics breakthrough, 3-D printed human heart, and paraplegia therapy
Venus-flytrap-like gripper could capture individual cells in the human body
Scientists use 'NanoVelcro' and temperature control to extract tumor cells from blood
(Phys.org)—An international group led by scientists at UCLA's California NanoSystems Institute has developed a new method for effectively extracting and analyzing cancer cells circulating in patients' blood.
Memory reformat planned for Opportunity Mars rover
(Phys.org) —An increasing frequency of computer resets on NASA's Mars Exploration Rover Opportunity has prompted the rover team to make plans to reformat the rover's flash memory.
How bacteria control their size
Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed ...
Microchip-like technology allows single-cell analysis
A U.S. and Korean research team has developed a chip-like device that could be scaled up to sort and store hundreds of thousands of individual living cells in a matter of minutes. The system is similar to ...
Researchers develop single cell genomics technique to reverse engineer developing lung
Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues ...
Stem cell study opens door to undiscovered world of biology
For the first time, researchers have shown that an essential biological process known as protein synthesis can be studied in adult stem cells – something scientists have long struggled to accomplish. The ...
Microrobots armed with new force-sensing system to probe cells
Inexpensive microrobots capable of probing and manipulating individual cells and tissue for biological research and medical applications are closer to reality with the design of a system that senses the minute ...
Engineers combine mechanics with biology to make key discovery about communication between cells
When the body forms new tissues during the healing process, cells must be able to communicate with each other. For years, scientists believed this communication happened primarily through chemical signaling. Now researchers ...
The secret math of plants: Biologists uncover rules that govern leaf design
Life scientists from UCLA's College of Letters and Science have discovered fundamental rules of leaf design that underlie plants' ability to produce leaves that vary enormously in size. In their mathematical ...
Herd mentality: Are we programmed to make bad decisions?
A natural desire to be part of the 'in crowd' could damage our ability to make the right decisions, a new study has shown.
Scientists 'herd' cells in new approach to tissue engineering
Sometimes it only takes a quick jolt of electricity to get a swarm of cells moving in the right direction.
Peer pressure's influence calculated by mathematician
(Phys.org) —A mathematician has calculated how peer pressure influences society.
