Scientists say medication also used after undergoing an organ transplant is capable of extending life with only brief use
COLOGNE, Germany — A drug that patients normally take during cancer therapy may have the power to increase the human lifespan, a new study reveals. Researchers in Germany say rapamycin can cause side-effects when patients take it as a lifelong anti-aging treatment. However, their new report finds even brief usage can have a dramatic impact on longevity while cutting down on side-effects.
Circa 2020 The axolotl’s ability to regenerate limbs has now be localized by researchers. This can lead to an end of illness and aging aswell.
A novel CRISPR-based genetic screen of candidate regeneration genes in haploid axolotl limbs reveals two genes required for proper regeneration.

Online gaming and other types of online social interaction have become increasingly popular during the pandemic, and increased remote working and investments in social technology will likely see this trend continue.
Carnegie Mellon mechanical engineering researchers have developed a new scalable and reproducible manufacturing technique that could accelerate the mainstream adoption and commercialization of soft and stretchable electronics.
The next generation of robotic technology will produce soft machines and robots that are safe and comfortable for direct physical interaction with humans and for use in fragile environments. Unlike rigid electronics, soft and stretchable electronics can be used to create wearable technologies and implantable electronics where safe physical contact with biological tissue and other delicate materials is essential.
Soft robots that safely handle delicate fruits and vegetables can improve food safety by preventing cross-contamination. Robots made from soft materials can brave the unexplored depths of the sea to collect delicate marine specimens. And the many biomedical applications for soft robots include wearable and assistive devices, prostheses, soft tools for surgery, drug delivery devices, and artificial organ function.

The groundbreaking research that established the connection between Alzheimer’s.
Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.
Summary: Brief exposure to Rapamycin, a promising anti-aging drug that has positive effects on health and lifespan, has the same effect as long-term exposure to the drug in animal models. The findings pave the way for testing the effects of short-term rapamycin exposure on the lifespan of humans.

Imagine you could take a medicine that prevents the decline that come with age and keeps you healthy. Scientists are trying to find a drug that has these effects.
A new method that increases the signal from CRISPR-based diagnostic tests, removing the need for amplification of DNA or RNA in a sample, could be used to quickly diagnose heart attacks and differentiate between cancer types.
A discovery made by researchers at the University of California, Irvine on how a certain protein is activated in tumor cells may lead to more effective treatments for some of the most deadly types of cancer. The finding, which was led by scientists at the School of Biological Sciences, may potentially result in treatment options for the especially dangerous melanoma and pancreatic adenocarcinoma, as well as the most common type of childhood brain cancer and adult skin cancer. The study was published in the journal Life Science Alliance.
The GLI1 protein, which is essential for cell development but has also been linked to a number of cancers, was the subject of the finding. The Hedgehog signaling pathway, also known as HH, usually activates GLI1. However, scientists have known for almost a decade that crosstalk, or interaction, between HH and the mitogen-activated protein kinase pathway, has a role in cancer.
“In some cases, proteins in one pathway can turn on proteins in another,” said lead author A. Jane Bardwell, a project scientist in UCI’s Department of Developmental and Cell Biology. “It’s a complex system. We wanted to understand the molecular mechanism that leads to GLI1 being activated by proteins in the MAPK pathway.”
