Cygnus Cargo Ship arrives at space station with cookie dough, mice and more

An unoccupied Cygnus cargo ship arrived at the International Space Station early Monday (4 November) to deliver more than 4 tons of fresh supplies, including cookie dough for a delicious experiment. Astronauts on the station used a robotic arm to kill the spacecraft Cygnus NG-12, called SS Alan Bean, in honor of Apollo 12 lunar Alan Bean, who died earlier …

Scientists extend the life of mice by 12% by optimizing telomeres

Scientists used specially cultured embryonic stem cells to produce mice whose cells had particularly long telomeres. Telomeres are DNA segments at the ends of chromosomes that help protect the genetic information they contain. Extension of Telomeres in the Embryonic Stem Cells could pave the way for slowing aging without genetic modification. Scientists successfully extended the average lifespan of mice by …

Scientists create super mice that can see infrared light

Could science ever give us superhuman abilities? A recent study suggests that this is indeed possible after researchers have used a nanoparticle solution to allow normal mice to see in the near infrared. Credit: Pixabay. "When we look at the universe, we only see visible light," said Gang Han, the project's lead researcher and researcher at the University of Massachusetts …

NASA fed cockroaches and mice with Apollo 11 moon samples

But it has not stopped yet. Astronauts Neil Armstrong and Buzz Aldrin were able to secure moon samples from the lunar surface of the Apollo 11 mission and return them to Earth. To ensure the safety of the lunar samples on Earth, scientists said NASA had to run a series of tests to make sure that contamination was not possible. …

Why are these mice hallucinating? Scientists are in their heads

In a lab at Stanford University School of Medicine, mice see things. And not because they were given medication. With the new laser technology, scientists have induced certain hallucinations in mice by switching on some neurons with light rays. The results reported the researchers on Thursday in the journal Science. The technique promises clues to how the billions of neurons …

Stem cells from hair follicles can repair damaged neurons in mice

Melanocyte stem cells from the telogen phase or resting phase of the mouse hair follicle (green, left field) within the CD34-positive bulge area (red) (left field) differentiate and form dense myelin sheaths ( right field) in the brain of myelin deficient mice. Picture credits: Sandeep Joshi, University of Maryland School of Medicine A subset of stem cells in hair follicles …

NASA video: Mice have fun in the weightless space station

NASA shared a video in which mice learned how to move in weightlessness on a space station. The images are part of a study to understand how space affects astronauts on longer missions. The mice ate, cleaned and cuddled, but adapted the behavior to the weightless environment. Some walked in circles around their cage, a behavior NASA called "race tracking." …
