  • The New Herbalism: Synthetic Biology Provides Alternative Sources for Herbal Extracts

    Throughout human history, there has been an extensive reliance on herbs (and their extracts) as sources of medicine, and such dependence still stands today. Indeed, a significant number of blockbuster drugs, ranging from quinine extracted from Cinchona and Remijia spp. for malaria treatments to paclitaxelfrom pacific yew (Taxus brevifolia) for tumor suppression, are still being extracted from plants rather than using chemical synthesis appr .. ...

  • New Antibiotics Prevent Hearing Loss

    By: Ayanna Flegler, PreScouter Global Scholar Bacterial infections remain a constant threat to human health. As treatment for such infections, antibiotics are used to either kill or prevent growth of bacteria. Aminoglycosides represent a widely used class of antibiotics that are effective, but can have a detrimental side effect of hearing loss. This reduction in hearing occurs when hair cells within the ear are lost as a result of aminoglycosides entering ear compartments. .. ... READ MORE

  • Breadth Of A Human Hair Equals The World’s Thinnest Endoscope

    STANFORD UNIVERSITY, CALIFORNIA, USA. An endoscope that has a width of a human hair has been developed by a team of researchers. This new development can provide more information on what really transpires in areas of the human body that has never been observed or seen before. Joseph Kahn and colleagues from Stanford University, California created an endoscope from just a single optical fiber. This instrument is used to look inside the body. A typical endoscope usually cons .. ... READ MORE

  • Immune System Remembers Viruses It Has Never Been Exposed To

    STANFORD UNIVERSITY, CALIFORNIA, USA. A group of researchers were able to discover in a recent study that the human body's T-cells in the immune system has the ability to fight viruses even if the patient has not been exposed to that particular virus. The human body's T-cells are white blood cells being sent by the immune system to fight any virus that invades the body. Once the T-cells have successfully defeated the virus, some stay around and it turns into memory cells. .. ... READ MORE

  • Stanford Engineers Create World’s First Solar Cell Stickers

    STANFORD UNIVERSITY, CALIFORNIA, USA. Engineers have successfully created flexible and lightweight solar cells which may be attached to almost any surface just like a sticker. As compared to the typical kind of solar panels, these solar cells are so much lighter and cheaper. The team of engineers at Stanford had to create a silicon dioxide “sandwich” by placing a 300-nanometer film of nickel on top of a silicon dioxide wafer which is later covered with thin film solar .. ...

  • Self-Healing Synthetic Skin Can Also Conduct Electricity

    STANFORD UNIVERSITY, CALIFORNIA, USA. Researchers have developed a material that is closely similar to the human skin. Unlike other synthetic skins that were created before, this new one is as close as can be to the real thing. It has the ability to sense pressure and it can also heal cuts and tears. Before this medical breakthrough, the earlier versions of the synthetic skin were only able to heal by itself just once or under high heat. The new material is now able to he .. ... READ MORE

  • New Battery To Last For 1,000 Charge Cycles Without Degrading

    STANFORD UNIVERSITY, CALIFORNIA, USA. Researchers and engineers have recently developed a grid-scale battery that can last for about a thousand charges without degrading. Renewable energy has always been a serious problem because batteries easily degrade after a few hundred charges. Both solar and wind energy provide renewable energy but the batteries being used to store it is where the problems start. With the development of this grid-scale battery, we just got a step closer .. ... READ MORE

  • Cryptographic Neuroscience: A Game Of Hidden Passwords In Your Mind

    STANDFORD UNIVERSITY, CALIFORNIA, USA. A game has been developed recently to store intricate information such as passwords subconsciously. In this new technology, cryptography is combined with neuroscience. Some volunteers were able to use a learned password later on to pass a test but were not able to identify it when they were asked to do so. That means they cannot disclose the password, whether they are willing to or forced because they wouldn't remember it until they need .. ... READ MORE

  • Microbes That Clean Methane

    PENNSYLVANIA STATE UNIVERSITY, PENNSYLVANIA, USA & STANFORD UNIVERSITY, CALIFORNIA, USA. Methanogens are microbes that can convert electricity into methane gas can be a vital wellspring of clean and renewable energy. This could transform clean electricity from nuclear, solar and wind power into renewable methane fuel. Also, it could include other precious chemical compounds. Fossil fuel is the major source of methane. For those who do not know, methane is twenty times more .. ... READ MORE
