Scientists Have Powered a Basic Computer With Just Algae For Over 6 Months

Scientists Have Powered a Basic Computer With Just Algae For Over 6 Months

In a ghastly vision of a future cut off from sunlight, the machine overloads in the Matrix movie series turned to sleeping human bodies as sources of electricity. If they’d had sunlight, algae would undoubtedly have been the better choice. Engineers from the University of Cambridge in the UK have run a microprocessor for more … Read more

Scientists Have Revived a Glimmer of Activity in Human Eyes After Death

Scientists Have Revived a Glimmer of Activity in Human Eyes After Death

Scientists have momentarily restored a faint twinkle of life to dying cells in the human eye. In order to better understand the way nerve cells succumb to a lack of oxygen, a team of US researchers measured activity in mouse and human retinal cells soon after their death. Amazingly, with a few tweaks to the … Read more

We May Have Caught a Supermassive Black Hole Flipping Its Entire Magnetic Field

We May Have Caught a Supermassive Black Hole Flipping Its Entire Magnetic Field

Black holes are powerful cosmic engines. They provide the energy behind quasars and other active galactic nuclei (AGNs). This is due to the interaction of matter with its powerful gravitational and magnetic fields. Technically, a black hole doesn’t have a magnetic field on its own, but the dense plasma surrounding the black hole as an … Read more

Extreme ‘Black Widow’ Pulsar Detected Just 3,000 Light-Years Away

Extreme 'Black Widow' Pulsar Detected Just 3,000 Light-Years Away

There are some strange objects lurking in our galaxy, and astronomers have just spied an extreme new candidate roughly 3,000 to 4,000 light-years away. After investigating mysterious flashes of light coming from the system, researchers have detected what they suspect is an elusive ‘black widow’ star – a rapidly spinning pulsar that’s kept alive by … Read more

New Eye Drops Improve Aging Vision Without Glasses. Here’s How They Work

New Eye Drops Improve Aging Vision Without Glasses.  Here's How They Work

When people get into their 40s and beyond, their close-up vision starts to worsen. For many people, cranking up the font size on a phone or maxing out the brightness on a computer is the only way to be able to read some text. This condition is known as presbyopia, and it affects around 128 … Read more

Something’s Glowing at The Galactic Core, And We Could Be Closer to Solving The Mystery

Something's Glowing at The Galactic Core, And We Could Be Closer to Solving The Mystery

Something deep in the heart of the Milky Way galaxy is glowing with gamma radiation, and nobody can figure out for sure what it might be. Colliding dark matter has been proposed, ruled out, and then tentatively reconsidered. Dense, rapidly rotating objects called pulsars were also considered as candidate sources of the high-energy rays, before … Read more

Look at This Epic NASA Backpack Designed For Astronauts on The Moon

Look at This Epic NASA Backpack Designed For Astronauts on The Moon

Human explorers on the Moon may be able to send back unprecedented, finely detailed maps of the lunar surface, thanks to a new backpack device developed by NASA and its partners. It’s called the Kinematic Navigation and Cartography Knapsack (KNaCK for short), and it’s equipped with a portable LIDAR scanner that constantly scans the ground … Read more

An Ancient Namibian Stone Could Hold The Key to Unlocking Quantum Computers

An Ancient Namibian Stone Could Hold The Key to Unlocking Quantum Computers

One of the ways we can fully realize the potential of quantum computers is by basing them on both light and matter – this way, information can be stored and processed, but also travel at the speed of light. Scientists have just taken a step closer to this goal, by successfully producing the largest hybrid … Read more

A Powerful ‘Space Laser’ Has Been Detected Beaming From Deep Space

A Powerful 'Space Laser' Has Been Detected Beaming From Deep Space

Powerful, radio-wavelength laser light has been detected emanating from the greatest distance across deep space yet. It’s a type of massless cosmic object called a megamaser, and its light has traveled for a jaw-dropping 5 billion light-years to reach us here on Earth. The astronomers who discovered it using the MeerKAT radio telescope in South … Read more
