  • several other flexible Li-ion batteries have been developed already, none has achieved a sufficient performance in operation stability to be applied to commercial products
  • the electrodes for these batteries can only be made of a few materials due to fabrication difficulties, and

  • Then, using sticky tape, the researchers peeled the mica substrate away, layer by layer
  • After about 10 minutes of peeling, the researchers could remove the entire mica substrate without damaging the thin-film battery.
  • Next, the flexible battery is transferred onto a flexible polymer sheet and capped with another flexible polymer sheet
  • tests, the researchers demonstrated that the new flexible Li-ion battery has the highest charging voltage (4.2 V) and charging capacity (106 μAh/cm2) ever achieved for flexible Li-ion batteries
  • also demonstrated that the battery could be bent with a high curvature angle
  • after 100 charge-discharge cycles, the battery lost some of its capacity
  • Depending on the degree of bending deformation, it maintained between 88.2% and 98.4% of its original capacity.
  • In the future, the researchers plan to improve the battery performance, particularly its energy density, as well as work on mass production through a one-step laser lift-off process instead of using sticky tape

  • a neurobiologist at University of California–Irvine
  • Huntington’s disease occurs when the C-A-G sequence of DNA base pairs repeat too often on the HTT gene, resulting in an abnormally long version of the huntingtin protein, that therefore folds incorrectly and forms clumps in the brain
  • usually begins to affect people in their 30s and 40s, causing movement problems and early death
  • No drug is currently available to stop the disease from progressing
  • For their experiment, researchers fed methylene blue mixed with food for a week to Drosophila flies

  • Scientists have known that cerebrospinal fluid or CSF plays an important role cleansing brain tissue, carrying away waste products and carrying nutrients to brain tissue through a process known as diffusion
  • The newly discovered system circulates CSF to every corner of the brain much more efficiently, through what scientists call bulk flow or convection
  • It's as if the brain has two garbage haulers – a slow one that we've known about, and a fast one that we've just met
  • How has this system eluded the notice of scientists up to now
  • the system operates only when it's intact and operating in the living brain, making it very difficult to study
  • study the living, whole brain, the team used a technology known as two-photon microscopy, which allows scientists to look at the flow of blood, CSF and other substances in the brain of a living animal
  • If the glymphatic system fails to cleanse the brain as it is meant to, either as a consequence of normal aging, or in response to brain injury, waste may begin to accumulate in the brain. This may be what is happening with amyloid deposits in Alzheimer's disease
  • Perhaps increasing the activity of the glymphatic system might help prevent amyloid deposition from building up or could offer a new way to clean out buildups of the material in established Alzheimer's disease
  • took an in-depth look at amyloid beta
  • found that more than half the amyloid removed from the brain of a mouse under normal conditions is removed via the glymphatic system
