A team of researchers built a web-based app called MapTrek. When synced with a Fitbit, MapTrek allows users to go on virtual walking tours of locations such as the Grand Canyon or Appalachian trail while competing against other users. A study showed MapTrek and Fitbit users averaged 2,200 more steps per day than a control group that used only Fitbits.

Novel therapy delays muscle atrophy in Lou Gehrig's disease model

Added: 13.07.2018 11:38 | 0 views | 0 comments

#zrodlo

Supplementing a single protein found in the spinal cord could help prevent symptoms of Lou Gehrig's disease, according to a new study. Researchers found high levels of the protein -- called mitofusion 2 or Mfn2 -- prevented nerve degeneration, muscle atrophy, and paralysis in a mouse model of the disease. Since Mfn2 is often depleted during Lou Gehrig's, the new study suggests supplementing it could be a novel therapeutic approach for the disease.

#zrodlo

Every year, more than one in three individuals aged 65 and older will experience a fall. Treatment and awareness of falling usually happens after a fall has already occurred. Researchers wanted to see if they could predict an individual's risk of falling so that preventative measures could be taken to reduce this risk.

#zrodlo

Understanding how a robot will react under different conditions is essential to guaranteeing its safe operation. But how do you know what will break a robot without actually damaging it? A new machine learning method can use observations made under safe conditions to make accurate predictions for all possible conditions governed by the same physical dynamics.

#zrodlo

A large multinational team of astronomers has found the first evidence of a source of super-energetic neutrino particles: a distant blazar — the nucleus of a giant elliptical galaxy that fires off particles in massive jets of elementary particles — about 4 billion light-years from Earth. Neutrinos are uncharged subatomic particles that normally pass by [...]

#zrodlo

Findings from an animal study suggest that a non-invasive imaging technique could, with further development, become a tool to assess immune system recovery in people receiving treatment for HIV infection. Researchers used single-photon emission computed tomography (SPECT) and a CD4-specific imaging probe to assess immune system changes throughout the bodies of macaques infected with SIV following initiation and interruption of antiretroviral therapy (ART). They evaluated pools of CD4+ T cells in tissues.

Scientists have developed a method to measure how well cancer drugs reach their targets inside the body. It shows individual cancer cells in a tumor in real time, revealing which cells interact with the drug and which cells the drug fails to reach. The findings could help clinicians decide the best course and delivery of treatment for cancer patients in the future.

Turbulence is a critical physical factor that promotes the large-scale production of functional platelets from human induced pluripotent stem cells, researchers reportl. Exposure to turbulent energy in a bioreactor stimulated hiPSC-derived bone marrow cells called megakaryocytes to produce 100 billion platelets -- blood cell fragments that help wounds heal and prevent bleeding by forming blood clots.
