  • Donald Ingber is leading efforts to develop organ-on-a-chip devices to replace animal tests

    ...display different sensitivities to radiation exposure that precisely match those previously observed in humans,” Ingber says. In another example, researchers from Wyss and Emulate worked with scientists at the pharmaceutical company Janssen to address a problem for which there weren’t good animal models. The company had an antibody that showed no toxicity... […]

  • Cell membrane coating as a platform nanotechnology for medicine

    ...display, which can be taken advantage of for immune modulation. Stem cell membrane-coated nanoparticles Stem cells are another class of cells that have been leveraged to make membrane coatings. The cells themselves have been widely explored for various therapeutic purposes, especially in the field of regenerative medicine. They are relatively easy to work with, as techniques for their large-scale culture are widely reported. Stem cells display many special properties, including tumortropism, […]

  • As future batteries, hybrid supercapacitors are super-charged

    ...energy density of any comparable system as demonstrated by a team of Molecular Foundry users and staff. These ultracapacitors can be charged and discharged repeatedly (Advanced Materials, "Titanium disulfide coated carbon nanotube hybrid electrodes enable high energy density symmetric pseudocapacitors" ). The team’s new design approach also makes them very stable. The new supercapacitor performs far better than earlier versions. It is less likely to self-discharge or short circuit. […]

  • As future batteries, hybrid supercapacitors are super-charged

    ...nanotube electrodes coated with titanium disulfide deposited one atomic layer at a time. The magnified inset shows individual titanium disulfide coated carbon nanotube electrodes. (Image: Berkeley Lab) Capacitors are electrical components that store energy and are widely used in electronic devices. Typical supercapacitors, named for their ability to store more electrical charge than standard capacitors, store charge “physically” through the buildup of charges on their surfaces. […]

  • Energy Summit Discusses Future Of Powder River Basin Production, New Uses For Coal

    ...nanomaterials for mass use. The sci-fi sounding production is already used for things like water-resistant coats, electronic displays, or even dyes and pigments. Though, for now, it’s developed with expensive oil or gas feedstocks. At the Wyoming Energy Summit in Laramie Wednesday, Chris Matranga, a scientist at the U.S. Department of Energy's National Energy Technology Laboratory said coal could soon be used to make the same products at a much cheaper price. Carbon nanomaterial is […]

  • Potential alcohol addiction mechanism revealed

    ...display alcohol-addiction-like behavior have low levels of the transporter protein GAT-3 in their amygdala. This leads to excessive amounts of the neurotransmitter GABA in the space between nerve cells. One in eight American adults abuse or are dependent on alcohol at some point in their lives, according to a 2017 study. Researchers would like to design better drugs to help this segment of the population overcome alcohol addiction, but progress has been stymied because their test... […]

  • An artificial nerve system gives prosthetic devices and robots a sense of touch

    ...electronic neuron. The touch sensor and electronic neuron are improved versions of inventions previously reported by the Bao lab. Sensory signals from these components stimulate the third component, an artificial synaptic transistor modeled after human synapses. The synaptic transistor is the brainchild of Tae-Woo Lee of Seoul National University, who spent his sabbatical year in Bao's Stanford lab to initiate the collaborative work. "Biological synapses can relay signals, and also store […]

  • Researchers develop technology to generate electricity and hydrogen from live bacteria

    ...energy. The energy is channeled to chemical reaction centers, where water is broken down, while releasing a flow of hydrogen ions. The ions are then applied to generate chemical energy, which drives food production. Published in Nature Communications ( "Live cyanobacteria produce photocurrent and hydrogen using both the respiratory and photosynthetic systems" ), the study was conducted by three Technion faculty members: Professor Noam Adir from the Schulich Faculty of Chemistry, Professor […]
