Some Physicists Think Time May Be Slowing Down

Posted by in categories: physics, space

The universe is expanding at an ever-accelerating rate. At least, that’s what the vast majority of scientists would have you believe. But according to a team of Spanish physicists, it may not be the expansion of the universe that’s changing rate, but time itself. Time might be slowing down, and that means that it could eventually stop altogether.

Scientists Grew Bits of Human Eyeballs in a Dish to Save Our Sight

Posted by in category: biotech/medical

In a lab at Johns Hopkins University, little bits of human eyes are growin in a dish. When one thinks of an eye, they likely think of the full bulbous form — the lens, an iris; the vitreous body. These retinal organoids are not that. Technically, they’re retinas grown from human stem cells — globs of the white tissue that lines the very back of the eye. While growing eye globs is a technical marvel in itself, their creation has a compounded purpose. Scientists generated them to understand why we can even see color and to learn how we can help people who can’t.

“As a scientist, I think that you have to have a passion for what you’re doing and a connection to your organism,” organoid-creator and Johns Hopkins University graduate student Kiara Eldred tells Inverse. “I cared for the organoids every day in the beginning and then every other day as they got older. In the lab, my co-authors and I all kind of refer to them as our babies because we have to care for them all the time.”

In a study published Thursday in Science, Eldred and her team reveal why these retinas are so important. Humans have three types of color-detecting cells that sense red, green, or blue light. But the mechanisms behind why this is hasn’t been fully understood. Here, the team discovered that blue cells are made first, and then red and green cells later. Learning the timing of these cell formations was a novel finding — and made sense, considering we and other primates have something called trichromatic color vision.

Almost like Columbia: Two crew members dodge death by an inch in botched Russian space launch

Posted by in category: space

Today’s launch abort was the first ever failure of the Soyuz FG launch vehicle, since it started in service in 2001.


A botched launch of the Russian spaceship Soyuz narrowly avoided becoming the latest fatal space incident on Thursday. Rescue systems managed to save the lives of two crew members and conduct an emergency landing.

Moons can have moons and they are called moonmoons

Posted by in category: space

If a moon is big enough and far enough from its planet, it can host its own smaller moon, called a ‘moonmoon’ — and four worlds in our solar system fit the bill.
