Machine makes prescription drugs 'on demand'

Machine makes prescription drugs 'on demand'
Scientists have created a compact machine that can churn out thousands of doses of prescription medication in a day—putting the capabilities of a drug-manufacturing plant into a device the size of a kitchen refrigerator. Experts said the advance could eventually allow on-the-spot drug production in special circumstances—on the battlefield, during epidemics, after natural disasters, or in cases where a drug is needed for a rare medical condition, for instance.

Microfluidic device could speed up DNA insertion in bacteria

Microfluidic device could speed up DNA insertion in bacteria
Genetically engineering any organism requires first getting its cells to take in foreign DNA. To do this, scientists often perform a process called electroporation, in which they expose cells to an electric field. If that field is at just the right magnitude, it will open up pores within the cell membrane, through which DNA can flow. But it can take scientists months or even years to figure out the exact electric field conditions to reversibly unlock a membrane's pores.

Fluorescent biosensors light up metabolic engineering

Synthetic biologists are learning to turn microbes and unicellular organisms into highly productive factories by re-engineering their metabolism to produce valued commodities such as fine chemicals, therapeutics and biofuels.

The feasibility of 'printing' replacement tissue

The feasibility of 'printing' replacement tissue
Using a sophisticated, custom-designed 3D printer, regenerative medicine scientists at Wake Forest Baptist Medical Center have proved that it is feasible to print living tissue structures to replace injured or diseased tissue in patients. Reporting in Nature Biotechnology, the scientists said they printed ear, bone and muscle structures. When implanted in animals, the structures matured into functional tissue and developed a system of blood vessels.

Fallopian tubes grown in lab for the first time

Fallopian tubes grown in lab for the first time
Researchers in Germany have been able to grow the inner-most layer of fallopian tube cells in the lab for the first time. Rather than using them to develop transplants for women, the lab-grown cells are instead intended to help scientists further their knowledge of how diseases and infection develop, and subsequently spread, from the tube into other parts of a woman’s reproductive system.

L'Oreal unveils super-thin smart skin patch

L'Oreal unveils super-thin smart skin patch
Beauty giant L'Oreal has unveiled a smart skin patch that can track the skin's exposure to harmful UV rays at the technology show CES in Las Vegas. The product will be launched in 16 countries including the UK this summer, and will be available for free. It contains a photosensitive blue dye, which changes colour when exposed to ultraviolet light. By Zoe Kleinman, BBC.

Artificial skin communicates with the brain

Artificial skin communicates with the brain
Zhenan Bao, a professor of chemical engineering at Stanford, has been trying, for a long time, to develop a material that mimics skin's ability to flex and heal, while also serving as the sensor net that sends touch, temperature and pain signals to the brain. Ultimately she wants to create a flexible electronic fabric embedded with sensors that could cover a prosthetic limb and replicate some of skin's sensory functions.

Tissue-engineered 'liver' enables fast drug testing

Scientists have developed a new technique that produces a user friendly, low cost, tissue-engineered pseudo-organ, publishing the results in the journal Biofabrication. The chip-based model produces a faithful mimic of the in vivo liver inside a scalable fluid-handling device, demonstrating proof of principle for toxicology tests and opening up potential use in drug testing and personalised medicine.
