Wendelstein 7-X fusion reactor on path to plasma twice as hot as the Sun

The Wendelstein 7-X stellarator is an experimental nuclear fusion reactor designed to bring us closer to the prospect of clean, limitless energy, and since producing its first plasma in 2015 we’ve seen it take steady and significant steps toward that a… Continue reading Wendelstein 7-X fusion reactor on path to plasma twice as hot as the Sun

How the Moon, microbes and longer days may have given us more oxygen

Most of us have at some point in our busy lives wished there were more hours in the day. That wish actually came true billions of years ago as the Earth’s rotation slowed down – and now a new study hypothesizes that this is why we have so much oxygen n… Continue reading How the Moon, microbes and longer days may have given us more oxygen

Neuroscientists discover how taking breaks while learning improves memory

In the late 19th century German psychologist Hermann Ebbinghaus published an influential book exploring memory and learning. Ebbinghaus was the first to chronicle a learning phenomenon which became known as the “spacing effect.”Continue ReadingCategory… Continue reading Neuroscientists discover how taking breaks while learning improves memory

Individual isotopes measured in exoplanet atmosphere for first time

Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the first time, which can tell us about how it formed.Cont… Continue reading Individual isotopes measured in exoplanet atmosphere for first time

45,000-year-old human genomes reveal extent of Neanderthal interbreeding

Two new genetic studies have shed light on just how often our ancestors got frisky with Neanderthals. Scientists analyzed the genomes of 45,000-year-old human remains found in caves in Czechia and Bulgaria, including the oldest known genome of a modern… Continue reading 45,000-year-old human genomes reveal extent of Neanderthal interbreeding

Gorillas may use sound of chest-beating to indicate their body size

Although the chest-beating of male gorillas is a common behaviour, its purpose still isn’t entirely understood. Now, however, scientists believe it may serve as a means of acoustically indicating the size of the apes’ bodies – needless to say, bigger i… Continue reading Gorillas may use sound of chest-beating to indicate their body size

Robotic fish learns to match its swimming speed to the current

Fish have a sensory system known as the lateral line, which allows them to detect movements, vibrations and pressure gradients in the water. Scientists have now given a robotic fish its own version of that system, letting it determine the best swimming… Continue reading Robotic fish learns to match its swimming speed to the current

Experimental cancer drug targets mitochondria to starve tumors of energy

Mitochondria are structures inside cells that produce chemical energy – and since cancer cells are particularly energy-hungry, this could be a potential weakness to target. Now, researchers have developed an experimental drug that blocks mitochondrial … Continue reading Experimental cancer drug targets mitochondria to starve tumors of energy

Webs of molecular fibers kill cancer cells from the inside out

Researchers at the Max Planck Institute have demonstrated an intriguing new way to fight cancer by introducing molecular fibers into cells. While harmless to healthy cells, once these fibers encounter the specific environment of cancer cells they assem… Continue reading Webs of molecular fibers kill cancer cells from the inside out
