Enhanced water repellent surfaces discovered in nature

Enhanced water repellent surfaces discovered in nature Through the investigation of insect surfaces, Penn State researchers have detailed a previously unidentified nanostructure that can be used to engineer stronger, more resilient water repellent coatings. The results of this research were published today (July 17) in Science Advances. With an enhanced ability to repel droplets, this design could be applied to personal protective equipment (PPE) to better resist virus-laden particles, such as COVID-19, among other applications. "For the past few decades, conventionally designed water repellent surfaces have usually been based on plants, like lotus leaves," said Lin Wang, a doctoral student in the Department of Materials Science and Engineering at Penn State and the lead author of the...

Languages Will Change Significantly on Interstellar Flights

Languages Will Change Significantly on Interstellar Flights It’s a captivating idea: build an interstellar ark, fill it with people, flora, and fauna of every kind, and set your course for a distant star! The concept is not only science fiction gold, its been the subject of many scientific studies and proposals. By building a ship that can accommodate multiple generations of human beings (aka. a Generation Ship), humans could colonize the known Universe. But of course, there are downsides to this imaginative proposal. During such a long voyage, multiple generations of people will be born and raised inside a closed environment. This could lead to all kinds of biological issues or mutations that we simply can’t foresee. But according to a new study by a team of linguistics professors, ther...

A Day in the Life of a Private Astronaut

A Day in the Life of a Private Astronaut Morning routine Time on the ISS is set to UTC (Coordinated Universal Time) and the day begins around 6:00 a.m. And just like on Earth, everyone starts the day getting cleaned-up and refreshed. Being in a weightless environment there are no such thing as running water from a faucet or a nice warm shower, so you must make do with a lot of wet towels and no-rinse shampoo. Science Experiments The ISS is fundamentally a science laboratory with experiments being conducted in fields as diverse as physical & life sciences, remote sensing and technology development. Even the crew are subject to experiments to see how the human body reacts to living in space for extended periods of time. Our clients have taken the time to participate in some of the t...

More than Just Dust in the Wind

More than Just Dust in the Wind In the 50 years since the first Earth Day, the view from space has revolutionized our understanding of Earth’s interconnected atmosphere, oceans, freshwater, ice, land, ecosystems and climate that have helped find solutions to environmental challenges. If NASA’s Earth science has changed this much in 50 years, what will it look like in 50 more years? We asked some researchers what they thought. Here are their answers, in their own words. Mahta Moghaddam is a professor of electrical and computer engineering at the University of Southern California. She’s building a system that helps sensors sync their measurements. I am interested in creating new ways to observe the Earth. In particular, my team and I are building and expanding a system that will allow sc...

A brand new magnetar found, it’s only 240 years old

A brand new magnetar found, it’s only 240 years old Magnetars are some of the most ridiculous objects in the universe. Composed of the densest material possible spinning faster than your kitchen blender, they generate the absolute most powerful magnetic fields the cosmos has ever seen – and astronomers have recently spotted a newborn. Neutron stars are made of the leftover cores of massive stars. In the final moments before the cataclysmic death of the parent star, billions upon billions of tons of plasma crush into the center at a healthy fraction of the speed of light. That intense crushing squeezes down the core to unimaginably high densities. Those densities – and the temperatures that go with them – are enough to shove electrons into protons, turning the core into a giant ball of ...
