Smartwatch-activated gene switch could help treat diabetes

Smartwatch-activated gene switch could help treat diabetes

Researchers from ETH Zürich have developed a gene switch that is operated using the green LED light emitted by commercial smartwatches. Typically, that green LED light is used for the pulse rate detection feature. However, the new approach created by the researchers could be used to treat diabetes in the future.

MQ-25 autonomous aircraft refuels another aircraft for the first time

MQ-25 autonomous aircraft refuels another aircraft for the first time

The United States Navy and Boeing have announced a first in aviation history. The Navy and Boeing have been testing MQ-25 unmanned aircraft known as the MQ-25 T1 test asset. In a recent test, the MQ-25 was able to perform aerial refueling of a U.S. Navy F/A-18 Super Hornet, demonstrating its aerial refueling mission for the first time.

Rotifers may be tougher than tardigrades

Rotifers may be tougher than tardigrades

A microscopic creature known as the tardigrade, sometimes called a water bear, is extremely tough and resilient. They're so tough and resilient that NASA has been studying the microscopic creatures in an attempt to learn how they're able to survive incredibly harsh conditions such as being frozen for decades or being exposed directly to the vacuum of space. The tiny creatures were thought to be the toughest on the planet, but there's a creature that might be even tougher.

Graphene leveraged to create ultra-high density hard drives

Graphene leveraged to create ultra-high density hard drives

A new study has confirmed that graphene can be used to create ultra-high density hard disk drives that offer up to ten times the amount of storage compared to current technologies. The study was published by researchers at the Cambridge Graphene Center in collaboration with teams at the University of Exeter, India, Switzerland, Singapore, and the US. While many computers are turning to solid-state storage devices today, hard drives are still widely used to store files in computers in large part because they are cheap and can store massive volumes of data.

Researchers create new optical biosensor to detect cancer

Researchers create new optical biosensor to detect cancer

Biosensors are important diagnostic devices that have to be quick, cheap, and easy to use. It's also beneficial if biosensors are compact and autonomous so they can be used by anyone from doctors down to the patient themselves. Most optical biosensors require a wide range of light colors, like a rainbow, to operate reliably.

This carbon nanotube “reactor” could one day power microscopic robots

This carbon nanotube “reactor” could one day power microscopic robots

Tiny carbon nanotubes that can generate energy simply through bobbing in a special liquid could one day be a breakthrough power source for micro-robotics or even smaller devices, researchers at MIT say. The approach could also provide a new and far more efficient source of electricity for electrochemistry, tapping power from the environment to make chemical conversions that rely less on traditional power sources.

Researchers image the human brain using ultrasonic sound and laser light

Researchers image the human brain using ultrasonic sound and laser light

Researchers from Caltech and the University of Southern California have demonstrated a new technology that is able to image the human brain using laser light and ultrasonic sound waves. The technology is known as photoacoustic computerized tomography or PACT. Previous versions of PACT technology have been used to image the internal structure of a rat in a laboratory.

NASA shoots tardigrades into space to help improve astronaut health

NASA shoots tardigrades into space to help improve astronaut health

Tardigrades are found on every continent of the planet and can survive some of the most extreme environments on earth. Tardigrades, also known as water bears, are tiny microscopic creatures with eight legs resembling a bear under the microscope. The tiny creatures can survive some extremely harsh conditions, and NASA wants to understand how they can tolerate these environments.

Astronomers think they discovered a new magnetar bringing the total to 25

Astronomers think they discovered a new magnetar bringing the total to 25

Astronomers have made a discovery that could be significant. On June 3, astronomers received a brief x-ray burst that happened close to the galactic plane. The burst was captured by the Swift Burst Alert Telescope, and follow-up analysis have seemingly confirmed the burst was emitted by a previously unknown magnetar.
