Does the human brain have an Achilles heel that ultimately leads to Autism? With a revolutionizing novel system that combines brain organoid technology and intricate genetics, researchers can now comprehensively test the effect of multiple mutations in parallel and at a single-cell level within human brain organoids. This technology, developed by researchers from the Knoblich group at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences and the Treutlein group at ETH Zurich, permits the identification of…

… by converting it into methanol with a new enzyme. A team led by Professor Osami Shoji at Nagoya University in Japan has developed a technology to convert methane, the principal component of natural gas, into methanol at room temperature in water. They used an enzyme that can be easily mass-produced, offering the possibility of a cheap and effective means to reduce the carbon footprint of natural gas. They published the results in ACS Catalysis.  Methane is the key component…

Researchers have invented a nano-thin superbug-slaying material that could one day be integrated into wound dressings and implants to prevent or heal bacterial infections. The innovation – which has undergone advanced pre-clinical trials – is effective against a broad range of drug-resistant bacterial cells, including ‘golden staph’, which are commonly referred to as superbugs. Antibiotic resistance is a major global health threat, causing about 700,000 deaths annually, a figure which could rise to 10 million deaths a year by 2050…

The EU-funded Human Brain Project (HBP) comes to an end in September and celebrates its successful conclusion today with a scientific symposium at Forschungszentrum Jülich (FZJ). The HBP was one of the first flagship projects and, with 155 cooperating institutions from 19 countries and a total budget of 607 million euros, one of the largest research projects in Europe. Forschungszentrum Jülich, with its world-leading brain research institute and the Jülich Supercomputing Centre, played an important role in the ten-year project….

… lays foundation for future glioblastoma therapy. The discovery of a previously unknown molecular target has inspired what may become a therapeutic breakthrough for people with glioblastoma, the most common and aggressive brain cancer. When people hear the word “cancer” they often picture a single mass, but glioblastoma cells are also highly invasive and spread quickly from the central mass, making it very difficult to fully eradicate. Even with current treatments such as temozolomide, the standard chemotherapy approved to treat…

Researchers at Washington University in St. Louis have developed a new computational approach to removing movement in images of expanding and contracting heart cells and tissues. By computationally removing movement, the algorithm mimics a drug’s action in stopping the heart, without compromising cellular structure or tissue contractility. Results of the research, led by Nathaniel Huebsch, an assistant professor of biomedical engineering, and Guy Genin, the Harold and Kathleen Faught Professor of Mechanical Engineering, both at the McKelvey School of Engineering, are published…

There’s a rhythm to developing life. Growing from a tiny cell cluster into an adult organism takes precise timing and control. The right genes must turn on at the right time, for the right duration, and in the correct order. Losing the rhythm can lead to diseases like cancer. So, what keeps every gene on beat? Cold Spring Harbor Laboratory (CSHL) Professor Christopher Hammell has found that in the worm C. elegans, this genetic orchestra has no single conductor. Instead, a quartet of…

Microbial or fungal biofilms on spacecraft can clog hoses and filters, or make astronauts sick. Space Station tests show that a surface treatment can help. After exposure in space aboard the International Space Station, a new kind of surface treatment significantly reduced the growth of biofilms, scientists report. Biofilms are mats of microbial or fungal growth that can clog hoses or filters in water processing systems, or potentially cause illness in people. In the experiment, researchers investigated a variety of surfaces…

Engineers create home test that uses saliva to detect periodontal disease. Engineers at the University of Cincinnati have developed a new device that can warn consumers about early risks of tooth decay from diseases such as gingivitis and periodontitis. Gingivitis, the earliest form of gum disease, is caused by bacteria. But not just any bacteria. The problem for researchers was getting a device to single out the particular type responsible for the disease, said Andrew Steckl, an Ohio Eminent Scholar…

… detects early signs of rejection. Wireless technology senses warning signs three weeks earlier than current methods. A body can reject a transplanted organ at any time — even decades later Signs of rejection must be caught early to intervene, preserve the organ Current monitoring methods are intermittent, imperfect and sometimes invasive New implant offers continuous monitoring by tracking the organ’s temperature When temperatures change, an alert is sent to a smartphone or tablet in real time Northwestern University researchers…

Opportunities for cancer treatment and wound healing. Cells are stimulated by robots measuring just 30 micrometers (µm) Technological platform developed to produce microrobots Ion channel mechanisms can be influenced A group of researchers at the Technical University of Munich (TUM) has developed the world’s first microrobot (“microbot”) capable of navigating within groups of cells and stimulating individual cells. Berna Özkale Edelmann, a professor of Nano- and Microrobotics, sees potential for new treatments of human diseases. A group of researchers at…

In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi’s lab and collaborators at MIT have created a device that mimics this biological concept in order to detect disease. Using their bioprotonic system, a device that integrates electronic components with biological components and uses electrical currents of protons, the researchers can detect…

Scientists investigate the unique absorption spectra of myelinated nerves as a way to visualize and differentiate them from their surroundings. Invasive medical procedures, such as surgery requiring local anesthesia, often involve the risk of nerve injury. During operation, surgeons may accidentally cut, stretch, or compress nerves, especially when mistaking them for some other tissue. This can lead to long-lasting symptoms in the patient, including sensory and motor problems. Similarly, patients receiving nerve blockades or other types of anesthesia can suffer…

Dresden researchers link excessive pressure in the bile transport network of the liver to the formation of liver cell rosettes, which are observed in many liver diseases. The liver produces bile, which the intestine uses for digestion. For the transport of bile, the liver relies on a network of microscopic tubings, known as bile canaliculi, formed by liver cells called hepatocytes. When the outflow of bile to the intestine is blocked, it collects in the liver and can lead to…

Genetic cluster in root fungus found to be the “on/off” switch for disease-causing behavior. Mold and diseases caused by fungi can greatly impact the shelf life of fruit and vegetables. However, some fungi benefit their hosts by aiding plant survival. Colletotrichum tofieldiae (Ct) is a root mold which typically supports continued plant development even when the plant is starved of phosphorus, an important nutrient for photosynthesis and growth. Researchers studied a unique pathogenic strain of the fungi, called Ct3, which…

Salk researchers identified new set of molecules that drive growth of human pancreatic cancer cell lines, potentially leading to new therapeutic targets. Pancreatic cancers are among the most aggressive, deadly tumor types and, for years, researchers have struggled to develop effective drugs against the tumors. Now, Salk researchers have identified a new set of molecules that fuel the growth of tumors in pancreatic ductal adenocarcinoma (PDAC), the most common type of pancreatic cancer. The new research, published in Nature Communications…
