A landmark study shows this age-old tech is the key.
The cure for aging has long been the Holy Grail of medicine. Emerging technologies, like the gene editing tool CRISPR, have opened the floodgates to what may be possible for the future of medical science. The key to slowing down aging, however, may lie in a simple and age-old technique.

Senescence in cancer cells
~~~
Sometimes, too much of a good thing can turn out to be bad. This is certainly the case for the excessive cell growth found in cancer. But when cancers try to grow too fast, this excessive speed can cause a type of cellular aging that actually results in arrested growth. Scientists at Duke-NUS Medical School have now discovered that a well-known signaling pathway helps cancers grow by blocking the pro-growth signals from a second major cancer pathway.
Inhibiting Wnt signaling with ETC-159 reactivates the hyperactive RAS-MAPK pathway, causing cells to led undergo senescence. Many cancers are driven by activating mutations in the RAS-MAPK signaling pathway which triggers a cascade of proteins that directs cells to grow, divide and migrate. Mutations in proteins involved in this cascade can turn on genes that make this process go into overdrive, causing cells to grow out of control and aggressively invade other parts of the body. However, too much RAS-MAPK signaling causes cancer cells to prematurely age, and eventually stop growing—a process called cellular senescence.
An exercise in pure mathematics has led to a wide-ranging theory of how the world comes together.
In the near future, large vessels carrying vehicles or other cargo across the ocean could be powered by wind, thanks to innovative sail technology.
Oceanbird, designed by Swedish engineering company, Wallenius Marine, is a futuristic concept for a PCTC (Pure Car and Truck Carrier) with capacity to carry 7,000 cars on long-distance ocean journeys. The project aims to prove that the global shipping community can transport goods in a sustainable way, and that low or zero-emission shipping is possible by using wind as the main energy source.
“We are proud to present our third iteration of our design, which we have worked with for several years,” said Per Tunell, COO of Wallenius Marine. “Shipping is a central function in global trade and stands for 90% of all transported goods, but it also contributes to emissions. It is critical that shipping becomes sustainable. Our studies show that wind is the most interesting energy source for ocean transports and with the 80-metre-high wing sails on Oceanbird, we are developing the ocean-going freighters of the future.”
In 2019, Switzerland-based Flyability had a mystery to solve at the Chernobyl Nuclear Power Plant. Was nuclear waste still present in one of the plant’s decommissioned reactors?
“At the time of the disaster, the fifth block of the Chernobyl Plant was under construction and nearing completion,” a Flyability spokesperson said. “Given the rush to leave, there was no record of whether the holding pools in Reactor Five had ever received the depleted uranium fuel bars for which they had been made.”
Fast forward 33 years – Chernobyl’s decommissioning team needed to know whether any nuclear waste remained in the reactor. Like a flying Sherlock Holmes, Flyability drones took the case.
Johns Hopkins University study of 10 billion years of microwaves reveals a warming predicted by dark matter theory.
Who says you can’t get hotter with age?
Researchers from Johns Hopkins University and other institutions have found that, on average, the temperature of galaxy clusters today is 4 million degrees Fahrenheit. That is 10 times hotter than 10 billion years ago, and four times hotter than the Sun’s outermost atmosphere called the corona. The findings are published in the Astrophysical Journal.
