Researchers figured out why ant teeth are so sharp

Researchers figured out why ant teeth are so sharp

Researchers from Pacific Northwest National Laboratory have investigated why some very small creatures can cut, puncture, and sting with such ease despite their small size. Researchers leveraged atomic-scale imaging to reveal minuscule details of how ants and other small creatures can use zinc to sharpen their various tools.

Stanford creates CasMINI gene editing system

Stanford creates CasMINI gene editing system

Researchers have created a significantly smaller version of the CRISPR gene editing system they call CasMINI. CRISPR has been used for gene editing for a long time and works like molecular scissors. Traditional CRISPR has multiple functions and can be used as a cutter or, in more advanced techniques, can be used to edit, label, or as an imager. While there are many different CRISPR systems in use today, Stanford researchers say they're all too large to deliver easily directly into living organisms, cells, and tissues.

Study shows avocados help women redistribute belly fat

Study shows avocados help women redistribute belly fat

Avocados are a food that many people enjoy adding and using in various types of recipes. A new controlled study has been conducted by researchers from the University of Illinois at Urbana-Champaign that found eating an avocado each day helped women redistribute belly fat. According to the researchers, the redistributed belly fat can help create a healthier body for women.

Researchers develop a way to convert carbon dioxide into methane

Researchers develop a way to convert carbon dioxide into methane

Researchers from Pacific Northwest National Laboratory have developed a new method allowing them to convert captured carbon dioxide into methane. Methane is a flammable gas and is the primary component of natural gas. The researchers were able to streamline a pre-existing process enabling the conversion of carbon dioxide into methane by reducing the material required to perform the reaction.

Mars Ingenuity helicopter flew low for its 13th flight

Mars Ingenuity helicopter flew low for its 13th flight

Yesterday, the Ingenuity helicopter completed its 13th flight taking it over the South Seitah area, where it captured images from a lower altitude than it has in the past. For the 13th mission, the helicopter again flew to the area of rock outcrops that it took images of during its 12 flight. The difference between flight number 12 and flight number 13 was the direction of the images. Flight 13 images were to looking in the opposite direction.

NASA confirms rescheduled spacewalk for September 12

NASA confirms rescheduled spacewalk for September 12

Astronauts aboard the ISS have been working to install new solar panel arrays outside the ISS over the last handful of weeks. The new solar panel arrays are upgrades to aging panels that have lost their effectiveness and will give the space station the power it needs to operate into the future. One of the spacewalks to install solar panels was previously canceled.

Parrots are getting free flight training courtesy of Aggie researchers

Researchers at Texas A&M University are harnessing a training technique that owners of parrots have used for training in their homes for decades. The goal of the training by Aggie researchers is to establish new flocks of birds in the wild. One key difference between the training being used at the university and the training typically used by parrot owners is that researchers aren't clipping the parrot's wings.

An ISS spacewalk is underway and the helmet-cam video is mesmerizing

Two Russian cosmonauts have been undertaking a spacewalk at the International Space Station today, and while their task may be to establish key links to the new Nauka module, it's also an opportunity for some jaw-dropping helmet-cam footage. Expedition 65 Flight Engineers Oleg Novitskiy and Pyotr Dubrov - both of Roscosmos - opened the airlock hatch at 10:41am EDT.

Scientists observed a new type of supernova for the first time

Scientists observed a new type of supernova for the first time

In 2017, astronomers detected an unusual source of extremely luminous radio waves. Scientists have now been able to determine what caused that unusual radio wave burst. According to a team of astronomers from Caltech, the radio flare resulted from a black hole or neutron star colliding with its companion star.

Augmented reality applications are helping astronauts repair the ISS

NASA is currently working hard to develop processes and technology acquired to send humans to the moon again. Currently, astronauts aboard the ISS are using augmented reality applications to assist them in making repairs within the station. The augmented reality system is part of an effort to reduce communications lag, which will be a significant challenge during lunar or Martian missions in the future.
