Until recently, it appeared impossible to keep healthy or diseased tissue from patients alive under laboratory conditions, let alone multiply it. Researchers at the Hubrecht Institute and the University Medical Center Utrecht have developed a culturing system for human liver stem cells and stem cells from pancreatic cancer. The cultured stem cells could replace donor organs for transplantation and offer new possibilities for personalized medicine.
Biomedical engineers from Carnegie Mellon University have created a full-size 3D bioprinted human heart model using their newly developed technique, Freeform Reversible Embedding of Suspended Hydrogels (FRESH). The model was created from MRI data using a specially built CD printer, which is capable of realistically mimicking the elasticity of cardiac tissue and sutures.
Electronic skin, or e-skin, may play a vital role in upcoming next-generation personalized medicine, prosthetics, robotics, and more. Scientists from King Abdullah University of Science and Technology have developed a durable e-skin capable of sensing objects from 20cm away, responding to stimuli in less than one-tenth of a second, and when used as a pressure sensor, could distinguish handwriting written upon it. Such e-skins could monitor a variety of biological information, such as blood pressure changes, which can then be shared and stored via Wi-Fi.
University of Pittsburgh School of Medicine researchers have combined synthetic biology with a machine learning algorithm to create human liver organoids with blood and bile-handling systems. When implanted into mice with failing livers, the lab-grown replacement livers extended the lifespan of the mice.
Experiments in space have revealed a new perspective into biological sciences, including insights into making human tissue. Gravity influences cellular behavior by impacting how protein and genes interact inside the cells, creating tissue that is polarized, a fundamental step for natural organ development. Unfortunately, gravity is against us when trying to reproduce complex tissues in the lab.
Researchers from the Francis Crick Institute and the University College London have rebuilt a human thymus, an essential organ in the immune system, using human stem cells and a bioengineered scaffold.
In what is believed to be a medical first, researchers from Johns Hopkins Medicine have enabled a quadriplegic man to control a pair of prosthetic arms with his mind. Surgeons implanted six electrodes into the patient’s brain to improve the sensation in his hands and allow him to mentally operate his prostheses. Now, the patient is able to perform simple tasks such as feeding himself.
On December 14th, the FDA approved genetically engineered pigs, known as GalSafe pigs, for both human food consumption and biomedical use. The pigs are free of a molecule that triggers meat allergies. It is the first time a genetically engineered animal has been approved for both food and medical uses, the FDA said.
Gene drive organisms (GDOs), developed with select traits that are genetically engineered to spread through a population, could dramatically alter the way society develops solutions to a range of daunting health and environmental challenges, from controlling dengue fever and malaria to protecting crops against plant pests.
Researchers from Rice University and the University of Texas MD Anderson Cancer Center have developed a microscope that can quickly assess margins of tumors within minutes of their removal.
Sewage sludge is a growing problem in the United States as we run out of solutions to deal with the copious amounts of landfill. Researchers from Texas A&M University proposed a method of using bacteria to produce bioplastics from the sludge.
Researchers from Carnegie Mellon University and the University of Washington have received a grant from the National Institutes of Health (NIH) to create a dural smart port that will allow direct access to the brain using optical and electrical stimulation, as well as recording. The port will use artificial intelligence to selectively stimulate tissue regrowth and seizure intervention.
The Tel Aviv University researchers behind this development believe that in the not-too-distant future, we will be able to buy dairy products produced from yeast in the supermarket that are identical in taste and color to dairy products that we consume today.
Scientists from the University of California, San Francisco have discovered a new way to control the immune system’s ‘natural killer’ (NK) cells. The findings hold promise for novel cell therapies, tissue implants that can evade immune rejection, and could also be used to enhance the ability of cancer immunotherapies to detect and destroy tumors.
Researchers from Rutgers University have created a 3D-printed smart gel that changes shape when exposed to light. The material was inspired by a class of mollusks, cephalopods (squids, octopi, or cuttlefish to name a few), that have chromatophores on their skin that allows them to change its color and pattern.
Capsaicin, a Chemical Which Makes Peppers Spicy, May Play Vital Role in Optimizing Solar Panels 🌶☀️🔋
Researchers from East China Normal University in Shanghai treated solar panels with capsaicin, the compound in peppers that make them hot, to better convert solar energy.
Researchers at the University of Birmingham and Duke University have successfully designed a polyester based biomaterial which enables them to control that rate at which it degrades along with its mechanical properties. Biological tissues are synthetic with varying elasticity which makes it considerably difficult to design biomaterials which have the right physical characteristics and can also degrade in the body as the chemistry used to develop a material’s mechanical properties will also effect the rate of degradation.
A breakthrough in the plastic industry has been made by NIOT (National Institute of Ocean Technology) by developing a bio-plastic film from macroalgae & PEG-3000. This innovation will potentially scale down the consumption of plastics that are non-biodegradable.
Scientists have discovered a novel technique to observe viral infection in real-time – the method utilizes microfluidics – the submillimeter control of fluids within a specific, geometric framework. Chemical engineers from Michigan Technological University have been capable of controlling viruses in a microfluidic device utilizing electric fields – which is primarily tricked-out of the microscope slide. The study released in the journal Langmuir looks at variations in the cell membrane and offers scientists a more clear concept of how antivirals function in a cell to stop the viral spread.
Researchers from Edith Cowan University are now using a precision technique called Mass Spectrometry to measure the proteins in beer. It has been found that the protein components in the grain called barley are responsible for most of the flavor, however proteins also interact with other small molecules to produce haze, which is generally undesirable in a lager. This technology can help to make sure food is safe and sustainable and tastes good.
Called the Aeson, the 900-gram device is powered by batteries and relies on sensor and biological materials to detect exactly which functions must be performed at any given moment. The firm Carmat has been working on this artificial heart for decades in response to the rising rates of heart disease across the world, which claims around 26 million lives per year. This artificial heart raises the hope for those awaiting transplants.
