Ethical questions raised after Elon Musk’s Neuralink company implants chip in monkey’s brain

Scientists and ethicists have questioned the ethical implications of human and cyborg hybridization experiments after a recent demonstration involving a monkey with a brain chip controlling a video game with its mind. On April 8, Elon Musk’s neurotechnology start-up Neuralink announced that it had successfully created a cyborg monkey that can play Pong with its mind using … Continue reading Ethical questions raised after Elon Musk’s Neuralink company implants chip in monkey’s brain

Inspired by spiders and fire ants, researchers develop a new unsinkable metal

Researchers from the University of Rochester have developed an extremely buoyant metal that can be used to make unsinkable ships. The researchers have drawn inspiration from fire ants and diving bell spiders, which have the remarkable ability to remain afloat or survive underwater for long periods of time. These creepy-crawlies are able to do this by trapping air in an … Continue reading Inspired by spiders and fire ants, researchers develop a new unsinkable metal

Breakthrough (and scary) technology allows scientists to collect DNA from the air

  A breakthrough technology allows scientists to obtain DNA samples from the air. The new technology collects environmental DNA (eDNA) shed by animals and humans for identification. Previously used to study fish, animals and invasive species, eDNA now shows promise in fields such as infectious disease epidemiology and forensics. Prior to the study, eDNA had been … Continue reading Breakthrough (and scary) technology allows scientists to collect DNA from the air

Researchers look to nanopores for new water treatment methods

For a while now, scientists have been looking into the use of nanomaterials as a way to clean water. The idea is that nanofilters made from these materials would be able to remove even the smallest impurities and contaminants in water. In a recent study published in The Journal of Physical Chemistry, a team led by researchers at the Massachusetts Institute … Continue reading Researchers look to nanopores for new water treatment methods

Scientists use nanoparticles as an alternative propulsion method for small spacecraft

Propellant is one of the most important things that any spacecraft needs to carry – without it, a spacecraft will be unable to move or change course. This is why spacecraft tend to carry a lot of it on board. Carrying propellant, however, brings its own set of problems. Not only is the chemical highly flammable, … Continue reading Scientists use nanoparticles as an alternative propulsion method for small spacecraft

Scientists develop artificial muscles powered by glucose: Findings will be used to develop a system that’s “even closer to a biological muscle”

A recent breakthrough in engineering and robotics just might blur the line between man and machine. Researchers from Linköping University in Sweden have successfully developed and created artificial muscles that run on glucose and oxygen — just like their organic counterparts. According to the researchers, they wanted to develop artificial muscles, which, instead of using traditional actuators powered by … Continue reading Scientists develop artificial muscles powered by glucose: Findings will be used to develop a system that’s “even closer to a biological muscle”

Updating fluid-powered machines: Scientists design bizarre-looking lionfish powered by a blood-like compound

You’ve heard of robots that can run, lift, jump and crawl. Now, prepare to see one that can bleed. In a paper published in the scientific journal Nature, a joint team of researchers from Cornell University and the University of Pennsylvania detailed how they built a soft robotic lionfish, complete with a multi-functional circulatory system. At its core: a blood-like compound that not … Continue reading Updating fluid-powered machines: Scientists design bizarre-looking lionfish powered by a blood-like compound

Underwater espionage: Can fish be used for underwater surveillance?

If the Pentagon is going to get its way, then chances are, it’s Nemo who’ll soon do the finding for the U.S. military. According to a statement published in its website, the Defense Advanced Research Project Agency (DARPA) – the Department of Defense‘s experimental research arm ?– says it is looking to recruit fish and other forms of undersea … Continue reading Underwater espionage: Can fish be used for underwater surveillance?

Single-use no more: Plastic bottles can be upcycled to more durable materials

Single-use plastics cause plastic pollution, a problem that affects rivers, lakes, and oceans. To address this concern, researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a recycling process that turns various materials made of polyethylene terephthalate (PET) into other useful products that will last longer. NREL’s research was published in the journal Joule. What is polyethylene terephthalate (PET)? Polyethylene terephthalate … Continue reading Single-use no more: Plastic bottles can be upcycled to more durable materials

Have you ever asked yourself what the possible dangers of 5G could be?

The dawn of the next generation of internet is upon us, but that may not be such a good thing. While proponents of the 5G (fifth generation) network are singing its praises, some experts have launched criticisms over the potential dangers presented by this new technology. In addition to the concerns about the lack of … Continue reading Have you ever asked yourself what the possible dangers of 5G could be?
