Everybody knows sleep is important, but there’s still a lot we don’t understand about what it actually does to the brain – and how its benefits could be boosted. To investigate, the US Army has awarded researchers at Rice University and other institutions a grant to develop a portable skullcap that can monitor and adjust the flow of fluid through the brain during sleep.

Most of us are familiar with the brain fog that comes with not getting enough sleep, but the exact processes going on in there remain mysterious. In 2012 scientists made a huge breakthrough in the field by discovering the glymphatic system, which cleans out toxic waste products from the brain during deep sleep by flushing it with cerebrospinal fluid. Disruptions to sleep – and therefore the glymphatic system – have been increasingly associated with neurological disorders such as Alzheimer’s.

Spaceship with a VASIMR engine will deliver about 60 metric tons of cargo to Mars in about 90 days.

The new fiber was created by placing hundreds of square silicon microscale digital chips into a preform that was then used to create a polymer fiber. By precisely controlling the polymer flow, the researchers were able to create a fiber with continuous electrical connection between the chips over a length of tens of meters.

The drug, molnupiravir, could be the first oral antiviral medication for covid-19.

By half, it would soon ask health officials around the world to authorise its use ⤵️.

If authorised for use, it would be the first pill shown to treat COVID and a major step in controlling the pandemic.

On the northwest coast of Taiwan, nestled between mudflats teeming with fiddler crabs and sweet-scented persimmon orchards, sits the world’s most important company that you’ve probably never heard of. Taiwan Semiconductor Manufacturing Co., or TSMC, is the world’s largest contract manufacturer of the semiconductor chips—otherwise known as integrated circuits, or just chips—that power our phones, laptops, cars, watches, refrigerators and more. Its clients include Apple, Intel, Qualcomm, AMD and Nvidia.

Inside its boxy off-white headquarters in sleepy Hsinchu County, technicians in brightly hued protective suits—white and blue for employees, green for contractors and pink for pregnant women—push polished metal carts under a sallow protective light. Above their heads, “claw machines”—nicknamed after the classic arcade game—haul 9-kg plastic containers containing 25 individual slices, or “wafers,” of silicon on rails among hundreds of manufacturing stations, where they are extracted one by one for processing, much like a jukebox selecting a record. Only after six to eight weeks of painstaking etching and testing can each wafer be carved up into individual chips to be dispatched around the planet.

“We always say that it’s like building a high-rise,” one TSMC section manager tells TIME, pointing to how his technicians diligently follow instructions dictated to them via tablet. “You can only build one story at a time.”

Some 90% of the world’s goods are transported by sea, which makes the current shortage a real problem.

In the 2030’s, gravitational-wave detectors will be thousands of times more sensitive than Advanced LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory supported by the National Science Foundation and operated by Caltech and MIT. It’s designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. It’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves. It consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana.

ESA’s Euclid mission has reached a new milestone in its development with successful testing of the telescope and instruments showing that it can operate and achieve the required performance in the extreme environment of space.

Euclid will study dark energy and dark matter. Whilst these cannot be seen directly by any telescope, their presence and influence can be inferred by observing the large scale distribution of galaxies in the universe.
