This fascinating off-grid lamp is powered by photosynthesis

Dutch designer Ermi van Oers has created an off-grid lamp that uses a living plant to produce light. The device, dubbed “Living Light,” uses microorganisms of plant origin to convert the chemical energy that a plant naturally produces during photosynthesis into an electric current. The lamp is fully self-sufficient, meaning it doesn’t have to be plugged into … Continue reading This fascinating off-grid lamp is powered by photosynthesis

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 brain stimulation techniques using light therapy that offer mental health benefits

Current studies on brain science affirm that light can stimulate brain cells (neurons). This general field and technique is called optogenetics and scientists use it to better understand the neural connections, electrical impulses and chemical signals that occur in the brain. In 2019, Shuo Chen, a postdoctoral scholar at the University of California in Berkeley received the Science … Continue reading Scientists develop brain stimulation techniques using light therapy that offer mental health benefits

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
