Rod-like devices are injected just beneath the skin and self-assemble into 3D scaffolds (I...

Scientists have had some success activating the body's immune system to take the fight to cancer and other diseases, a process known as immunotherapy. Now, a new method developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could advance this form of treatment even further. The technique involves the injection of biomaterials that assemble into 3D scaffolds inside the body to accommodate huge amounts of immune cells, a process that could trigger an attack on deadly infections ranging from HIV to cancer to Ebola.  Read More

Pulsar uses nuclear magnetic resonance to differentiate between horse meat and beef

Although eating horse meat is normal in many parts of the world, in other places, such as Britain, it rates almost on the same level as eating the family dog. So when it was discovered last year that horse meat was being passed off as beef, it literally put a lot of people off their dinner. To prevent a repeat of the episode, the Institute of Food Research (IFR) in Norwich and Oxford Instruments have developed a portable detector that can differentiate between horse meat and beef in about 10 minutes, yet is inexpensive and simple to use.  Read More

Muufri founders Ryan Pandya and CTO Perumal Gandhi are aiming for a marketable product by ...

“Got (synthetically bioengineered plant-based) Milk?” may not have the punch of the famous California dairy industry advert, but the founders of a Silicon Valley-based biotech startup are hoping their genetically engineered yeast will produce a dairy alternative as good or better than the cow version.  Read More

NASA astronaut Rick Mastracchio prepares to test the ultraviolet light decontamination har...

The International Space Station (ISS) is perhaps the most artificial environment that human beings have ever taken up residence in. It’s not the sort of place where you’d want a lab accident, because you can’t run out the door and wait in the carpark for the air to clear, so NASA uses gloveboxes to keep the crew and equipment separate from dangerous contaminants. To increase this level of safety and expand the number experiments the station can carry out, the space agency is fitting one of the larger gloveboxes with an Ultraviolet Germicidal Irradiation (UVGI) system to to prevent potentially dangerous microorganisms from escaping.  Read More

An artificial blood substitute being developed at the University of Essex could help overc...

According to the World Health Organization (WHO), over 107 million blood donations are collected around the globe every year, most of which goes on to help save lives. However, while the need for blood is global, much of that which is donated is not accessible to many who need it, such as those in developing countries. And of the blood donated in industrialized countries, the amount often falls short of requirements. To help address this imbalance, scientists at the University of Essex are developing an artificial blood substitute that would provide a benign, virus-free alternative for blood transfusions.  Read More

A modifier protein that can be used to interfere with the plant's growth repression protei...

Researchers have discovered a new way to increase plant growth by suppressing the natural response to environmental stress. The scientists have found a modifier protein that can be used to interfere with the plant's growth repression proteins independently of the previously identified hormone Gibberellin. They believe this will lead to higher crop yields, even in unfavorable conditions.  Read More

Scientists convert human embryonic stem cells into functional lung epithelial cells (green...

Researchers at Columbia University Medical Center (CUMC) have transformed human stem cells into functional lung cells, paving the way for ultimately creating bioengineered lungs using the patient's own cells. Besides being able to generate lung tissue for transplants, these cells could also be used to study lung development and potentially find more advanced treatments for lung diseases.  Read More

A 3D printer built at Oxford University can produce droplet networks capable of folding in...

While the prospect of 3D printers pumping out biological tissues and replacement organs has many justifiably excited, researchers at Oxford University have gone in a slightly different direction with the creation of a custom 3D printer capable of producing synthetic materials that have some of the properties of living tissues. Rather than being intended for supplying spare parts for damaged replicants, the new materials could be used for drug delivery or replacing or interfacing with damaged tissues inside the human body.  Read More

The Photonic Professional GT - the world’s fastest commercially available 3D printer for m...

3D printing has already gone well beyond the bounds of model making, and biotechnology is one of the new frontiers where the technology is set to make a huge impact. Nanoscribe GmbH, a spin-off of the Karlsruhe Institute of Technology (KIT), is pushing the boundaries of this space with the release of what's claimed to be the world’s fastest and highest resolution commercially available 3D printer of micro- and nanostructures – the Photonic Professional GT.  Read More

Researchers have found a cost-effective way to produce an alternative to ambergris (Photo:...

Highly prized by perfume makers, ambergris is a natural material that fetches thousands of dollars per pound. The high price tag is due to the material's rarity, which is a result of its source – the digestive system of sperm whales, from which it is expelled to float around the ocean and has led to it being dubbed "floating gold." While its cost and the endangered status of the sperm whale has caused many perfume manufacturers to turn to synthetic alternatives, the most popular of these is laborious to produce. Now a team of researchers has developed a method to sustainably produce large quantities of an ambergris alternative.  Read More
