When cancer cells are closely packed together in a tumor, they’re able to communicate with each other and coordinate their movement throughout the body. What if we could interrupt this process? In this accessible talk about cutting-edge science, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating — and halt their fatal ability to spread.

This talk was presented at an official TED conference, and was featured by our editors on the home page.

To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos.

High-powered semiconductor lasers are used in materials processing, biomedical imaging and industrial research, but the emitted light they produce is affected by instabilities, making it incoherent.

The instabilities in the laser are caused by optical filaments; light structures that move randomly and change with time, causing chaos. Removing these instabilities has long been a goal in physics, but previous strategies to reduce filaments have usually involved reducing the power of the laser.

Smoothing out a material used in desalination filters could help combat worldwide water shortages.

With gentle pulses from gigantic lasers, scientists at Lawrence Livermore National Laboratory in California transformed hydrogen into droplets of shiny liquid metal.

Their research, reported on Thursday in the journal Science, could improve understanding of giant gas planets like Jupiter and Saturn whose interiors are believed to be awash with liquid metallic hydrogen.

The findings could also help settle some fractious debates over the physics of the lightest and most abundant element in the universe.

Half of the planet’s oxygen comes from tiny plants under the ocean’s surface—phytoplankton.

The United States and Russia aren’t the only two nations working hard at realizing their space-faring dreams. China has quickly ramped up its high-flying ambitions in the past couple of decades and late 2018 will mark a real milestone for the country’s space program. The country just announced that it plans on launching a lunar rover to the far side of the Moon in December of this year.

The announcement comes via China’s state-run news agency CCTV, and China seems bullish on the prospect of being the first country to explore the far side of Earth’s moon with a robotic rover.

The mission, named Chang’e 4, follows in the footsteps of its predecessor (you guessed it, Chang’e 3) which saw a rover nicknamed “Jade Rabbit” land on the near side of the Moon back in 2013. That rover ran out of steam in August of 2016, and the model that will be flying to the far side is built largely of backup parts from the Chang’e 3 mission.

Researchers are set to develop higher yield wheat varieties requiring less water after making a gene map.

Within 5 years, the world could widely accept that we are within striking distance of a post-aging world. This could be with the achievement of mice that would normally die at the age of three getting life extension at the age of two and living beyond 5 years. It might be after that with the similar treatments to reverse aging in dogs. It could be with the first age reversal treatments in humans that make people look significantly younger but also restore muscle and other body functions.
