Technological advancements surely have helped increase cancer survival rates, but why isn’t there a cure for cancer yet? We are well-versed with the importance of treatments like chemotherapy and radiation therapy, but are there any more advance treatments we can look forward to?
Cancer cells communicate with each other and coordinate their movement throughout the body. But this process can be interrupted. In this TED Talk, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating -- and halt their fatal ability to spread.
You probably have been eating radioactive materials all your life without you knowing it. Wonder what they do to your body?
Early today (Aug. 11), NASA is launching its newest spacecraft, called the Parker Solar Probe. The probe's mission is to study the outer corona of the Sun to better protect our tech-driven lifestyle against destructive solar storms that could take us back to the stone ages.
Plastic was long considered to be a revolutionary material. But, what has it turned into now? A trash – and millions of tons of it end up in the ocean every year. Of course there are plenty of attempts to thwart this growing problem, but this approach by the Ocean Cleanup seems to be the most effective. Here's how it works.
