April 12, 1961: The First Human in Space
Yuri Gagarin, the Soviet cosmonaut who was the first human in space. He orbited Earth in his Vostok 1 spacecraft for 108 minutes. The first human being broke free of the gravity bond with Earth, and orbited the planet.
Gagarin became an international celebrity at the time. He received the USSR’s highest honor, the Hero of the Soviet Union.

Scientists Translated Spiderwebs Into Music, And It's Beyond Stunning
Spiders rely quite significantly on touch to sense the world around them. Their bodies and legs are covered in tiny hairs and slits that can distinguish between different kinds of vibrations.

The Brain ‘Rotates’ Memories to Save Them From New Sensations
Some populations of neurons simultaneously process sensations and memories. New work shows how the brain rotates those representations to prevent interference.
During every waking moment, we humans and other animals have to balance on the edge of our awareness of past and present. We must absorb new sensory information about the world around us while holding on to short-term memories of earlier observations or events. Our ability to make sense of our surroundings, to learn, to act and to think all depend on constant, nimble interactions between perception and memory. Read on Quantamagazine.

We Finally Know How The Biggest Nuts Always Rise to The Top
The problem starts with Brazil nuts. The large edible seeds are a common fixture in mixed nut bags, but they're not to everyone's liking - especially since they get dry and bitter once past the peak of freshness. And to make matters worse, they alw
The world’s biggest flower, Rafflesia arnoldii, is a parasite that spends much of its life inside its vine hosts. New genomic work suggests that the parasites in this group of plants have lost an astonishing share of their genes.
The bizarre genome of the world’s most mysterious flowering plants shows how far parasites will go in stealing, deleting and duplicating DNA.

Our Sense of Time Is Warped When We Catch The Eye of Another Person
Our language weighs heavily with idioms and clichés about the human gaze. Whether they're windows to the soul, or we're staring daggers, eye contact communicates more about our intentions than words ever could alone.

Scientists Have Identified Four Distinct Types of Alzheimer's And What They Do to Us
The more we understand about Alzheimer's, the faster we can work towards better treatments and ultimately a cure, which makes discovering four distinct subtypes of the brain disease an important one.
The thorny thought experiment has been turned into a real experiment — one that physicists use to probe the physics of information.
The universe bets on disorder. Imagine, for example, dropping a thimbleful of red dye into a swimming pool. All of those dye molecules are going to slowly spread throughout the water. Physicists quantify this tendency to spread by counting the number of possible ways the dye molecules can be arranged. There’s one possible state where the molecules are crowded into the thimble. There’s another where, say, the molecules settle in a tidy clump at the pool’s bottom. But there are uncountable billions of permutations where the molecules spread out in different ways throughout the water. If the universe chooses from all the possible states at random, you can bet that it’s going to end up with one of the vast set of disordered possibilities. Read on Quantamagazine
