Are constellations of mini satellites the future of communication? Satellite constellations are groups of satellites working together, rather than as single satellites, orbiting the Earth. Many countries and companies are getting into this game, but there are some engineering challenges.

A satellite constellation is a group of artificial satellites, working together. In the coming decades, companies like SpaceX, and Samsung are planning to launch a number of satellite constellations. These satellites will allow users to enjoy more reliable connectivity, independent READ MORE

Using Reishi mushrooms to filter methane out of the atmosphere Both living and dead fungi were tested for their ability to capture methane from the atmosphere. Surprisingly, dead fungi performed the best and have high potential for reducing methane levels.

Could dead or living #fungi be used as a biofilter to trap and remove #methane, the potent #greenhousegas, from the atmosphere? Researchers including @shroominn from @UMNews tested both living and dead fungal biomass to determine their ability to capture methane.

Designing an airplane that can fly on Mars! First we put a rover on Mars, then a helicopter (Ingenuity). But what about airplanes? This study describes the design of special wings that will help airplanes fly in the thin Martian atmosphere

Can #airplanes fly on #Mars? Maybe! Find out the perfect wing shape for flying in the thin Martian atmosphere.

A new kind of battery that removes carbon dioxide from the air Engineers at MIT invented a device that uses something called "electro-swing absorption" to take carbon dioxide from the air and allow it to be stored or used for other industries.

Nature has been able to filter out CO2 from our air for millions of years. So how might a battery prove to be our own artificial tree? #sustainability #environment #carbonemissions

This new tiny biomedical device makes diagnosing cancer types easier A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs. It can deliver colored stains to tissue samples accurately, so that scientists can view cancer cells under the microscope more easily.

A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs! This paper, published in the Journal of Biomedical Microdevices, represents a step forward in lab technology. Creating a tiny READ MORE

Contaminants in groundwater can take over 20 years to break down But scientists have a method for removing the contaminants more quickly, using a underground barrier.

Have you ever driven past an old factory building and wondered what ever happened to the harsh chemicals that were used there? If you guessed that a lot of the chemicals ended up in the environment, you would be right. READ MORE

A special kind of bacteria lets cement fix itself Mineral-forming bacteria that grow best in fast-flowing liquid may be the glue that researchers need to close cracks in underground cement.

Cement is one of those common building materials that you can find just about anywhere. When the cement starts to get cracked, fixing it is generally an easy task that involves widening the crack slightly before filling it with more READ MORE

Bacteria with nanowires can electrocute metals instead of breathe Recycling Expensive and Toxic Metals with Bacteria

All life on Earth has to respire. For us this means inhaling oxygen to fuel our metabolism and exhaling waste gases like carbon dioxide. When we do this, we move the energy  from the food we eat to the oxygen READ MORE

What the ruby slippers from The Wizard of Oz can teach us about conservation Researchers from the Smithsonian meticulously analyze the 80-year-old ruby slippers and learned how to preserve them for future generations

Scientists use advanced lab techniques to examine every detail of the ruby slippers to understand what they are made of, the age of the materials, and their present state. As a result, they learned how to protect them from deteriorating further.

Scientists design an office chair that cancels noise Certain types of low frequency sounds can be distracting at work. This office chair may make open offices and work spaces with constant white noise a little more bearable.

Open office designs have been hailed for their economic benefits and helping people work together. On the other hand, a survey by a research firm showed that workers in an open office can lose up to 86 minutes of productivity per READ MORE
