New research is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via a direct interface with the brain.
Sartorius Stedim Biotech today made a cash offer to acquire the UK company TAP Biosystems Group plc (TAP Biosystems), through its wholly owned subsidiary Sartorius Stedim Biotech GmbH. The proposed transaction, which is subject to customary closing conditions, including the approval of TAP’s shareholders, values the equity of TAP Biosystems at approximately €33 million.
Inspired by how wireless communication networks use multiple radio frequencies to communicate with multiple users, researchers have developed a new high-speed microscopy technique that is an order of magnitude faster than current fluorescence-imaging technologies.
The report by scientists of a new hepatitis virus earlier this year was a false alarm, according to researchers who correctly identified the virus as a contaminant present in a type of glassware used in many research labs. Their finding highlights both the promise and peril of today’s powerful “next-generation” lab techniques.
A joint research team is developing a new breast cancer screening technique that has the potential to reduce false positives, and, possibly, minimize the need for invasive biopsies. The new MRI device could improve both the process and accuracy of breast cancer screening by scanning for sodium levels in the breast.
A new laser, the Supra Scan Multi-spot Laser, is helping experts provide better treatment for eye diseases. This advanced laser can prevent blindness for some patients with serious conditions. The first patient received treatment from the laser for proliferative diabetic retinopathy on July 22.
Scientists are reporting an advance in smartphone-based imaging that could help physicians in far-flung and resource-limited locations monitor how well treatments for infections are working by detecting, for the first time, individual viruses.
Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. A team of researchers has created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment.
A research collaboration has combined Fourier Transform Infrared (FTIR) spectroscopy with computed tomography (CT-scans) to create a non-destructive 3-D imaging technique that provides molecular-level chemical information of unprecedented detail on biological and other specimens with no need to stain or alter the specimen.
Tiny silicon crystals caused no health problems in monkeys three months after large doses were injected, marking a step forward in the quest to bring such materials into clinics as biomedical imaging agents, according to a new study. The findings suggest that the silicon nanocrystals, known as quantum dots, may be a safe tool for diagnostic imaging in humans.
Engineers have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope. Such a system could greatly improve the efficiency of digital pathology, in which specialists need to review large numbers of tissue samples.
Newly trialed native algae species provide real hope for the development of commercially viable fuels from algae, scientists have found. The researchers have identified fast-growing and hardy microscopic algae that could prove the key to cheaper and more efficient alternative fuel production.
Researchers have unraveled the secret to byssus threads, the tiny natural bungee cords that mussels use to dangle loosely from rocks, piers or ships. Byssus threads, they found, are composed of a well-designed combination of soft, stretchy material on one end and much stiffer material on the other.
For the first time, scientists are working on developing a ‘nano-coating’ that would protect a vaccine from its environment both in transit and for storage. Using the latest chemistry advances, researchers hope to show how nano-silica can be grown around individual vaccine molecules, enabling a vaccine to be taken anywhere in the world without refrigeration.
Researchers are now reporting advances in complex three-dimensional structures development using gelatin-based microparticles to deliver growth factors to specific areas of embryoid bodies, aggregates of differentiating stem cells.
A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5½ years less than their southern counterparts because they breathed dirtier air.
Researchers working to design new materials that are durable, lightweight and environmentally sustainable are increasingly looking to natural composites for inspiration. While they have come up with hierarchical structures in the design of new materials, going from a computer model to the production of physical artifacts has been a challenge. Now, researchers have developed an approach that allows them to turn their designs into reality.
New technology under development is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body. The first planned use of the technology is a sensor that will detect the very early stages of organ transplant rejection.
An innovative method for treating potentially fatal brain aneurysms by filling them with foam-like plastics is a step closer to clinical trials after demonstrating an ability to promote healing at unprecedented levels. The treatment makes use of special plastics called polyurethane-based shape memory polymer foams (SMPs) and is considered a significant milestone in the development of the treatment of aneurysms.
Researchers have developed a new noninvasive system that allows people to control a flying robot using only their mind. The study goes far beyond fun and games and has the potential to help people who are paralyzed or have neurodegenerative diseases.
The ability to combine all of a patient’s neurological test results into one detailed, interactive “brain map” could help doctors diagnose and tailor treatment for a range of neurological disorders, from autism to epilepsy. But before this can happen, researchers need a suite of automated tools and techniques to manage and make sense of these massive complex datasets.
Invisalign, a San Jose company, uses 3-D printing to make each mouthful of customized, transparent braces. Mackenzies Chocolates, a confectioner in Santa Cruz, uses a 3-D printer to pump out chocolate molds. And earlier this year, Cornell University researchers used a 3-D printer, along with...
Paper is known for its ability to absorb liquids, making it ideal for products such as paper towels. But by modifying the underlying network of cellulose fibers, etching off surface “fluff” and applying a thin chemical coating, researchers have created a new type of paper that repels a wide variety of liquids– including water and oil.
A simple lab-based skin test which eliminates the risk of adverse reactions to new drugs, cosmetics and household chemicals has been developed by team of researchers. It uses real human skin and immune cells to show any reaction such as a rash or blistering indicating a wider immune response within the body.
Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. Researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules.
