Your liver is always less than three years old or younger

Joshua Hawkins — Tue, 28 Jun 2022 03:16:00 +0000

The liver is an amazing organ. Not only is it capable of regenerating itself to repair damage from toxins, like alcohol, but the liver apparently never ages, either.

According to new research, the liver is almost always just under three years old. The concept of liver age has been a medical conundrum for decades. Studying animal livers has yet to offer any kind of answer, so scientists with TU Dresden looked at human livers to try to discern more about our body’s filter.

Watch MIT’s fascinating little robot lightning bugs take flight

Joshua Hawkins — Mon, 27 Jun 2022 23:10:00 +0000

Fireflies are one of the best parts of warm summer nights. The dancing, flickering lights of these tiny bugs have enamored people for centuries. Now, a group of scientists at MIT have created robot lightning bugs inspired by nature. Not only can these robots fly, but they also emit light. Just like real-life fireflies.

From performing simple tasks to helping explore the Moon, humans have found many uses for robots. But what could robots the size of an insect do? Well, the possibilities, as it turns out, are quite endless.

This experimental treatment for a rare disease has a crazy side effect: A new hair color

Joshua Hawkins — Mon, 27 Jun 2022 15:17:00 +0000

A new experimental cystinosis treatment has proven successful but has also had an unintended side effect. According to a report, four out of five patients who have taken part in a clinical trial to treat cystinosis have seen a change in their hair color following treatment.

When someone has cystinosis, their body builds up an abnormal amount of cystine. This amino acid created crystals, called cystine crystals, throughout the body. That buildup can affect many parts of the body. And, because it’s genetic, the disease is passed down through families. Oftentimes, patients with cystinosis vomit a lot, suffer from dehydration, and can even develop more serious problems, too.

New study shows why it’s actually good to drink a beer a day

Joshua Hawkins — Sun, 26 Jun 2022 17:07:00 +0000

The healthiness of beer has been under scrutiny for quite a while. Some argue that even drinking two beers a day can damage your brain. Others say even a little alcohol can raise your risk of cancer. Now, though, the tables have turned, and scientists say drinking lager beer can actually be good for you. So long as you do it in moderation.

Researchers created gene-edited hamsters full of rage in an experiment gone wrong

Joshua Hawkins — Sun, 26 Jun 2022 14:05:00 +0000

A group of researchers made gene-edited hamsters that were meant to be less aggressive. The researchers used CRISPR, a gene-editing platform, to remove a gene they believed was responsible for aggressive behavior in hamsters. However, the genetic modification had a much different effect. Instead of being more docile, the hamsters became overly aggressive.

Curiosity has discovered ancient rocks formed by water on Mars

Mars was not always the rocky, lifeless planet that we know it to be now. At least, all of the science seems to point towards that truth. For years, NASA has been discovering more about our neighboring planet. And now, the space agency’s Curiosity rover has discovered even more evidence that water once covered parts of the Martian surface.

New paper claims Jupiter may have ‘eaten’ other planets

Joshua Hawkins — Fri, 24 Jun 2022 20:37:00 +0000

Jupiter has been quite a mystery for astronomers over the years. Despite being the largest planet within our solar system, we know very little about the inner workings of this gas giant. Now, though, NASA’s June space probe may have shed some new light on how the planet formed. Researchers now believe that Jupiter may have eaten other smaller planets to fuel its own growth.

The idea of one planet eating another might sound like something out of science fiction. After all, this isn’t Star Wars, where we have to worry about massive Death Star space stations or other planet killers. But, scientists believe that the fifth planet from our Sun, Jupiter ate planets during its formation.

For decades, we’ve been unable to look past the harsh gas clouds that cover the surface of the planet. Now NASA’s Juna space probe has given us a glimpse below. The researchers used gravitational data to peer past Jupiter’s clouds. The makeup of the rocky material at the gas giant's core suggests that Jupiter ate baby planets—often called planetesimals—to fuel its growth.

Growing a gas giant

It's a bold claim, but it is one that has been around for a while. With this new data, though, scientists finally have a little bit of evidence that Jupiter eating other planets could be more than just science fiction. It especially makes sense as the gas giant would have needed to pull in a lot of mass to become as massive as it has become.

There are two main theories about how Jupiter formed. The first is that Jupiter accumulated billions of smaller space rocks. These rocks eventually formed the condensed core that makes up the gas giant. The other theory, and the one this new evidence supports, is that Jupiter may have eaten other planets to grow as large as it has.

These planets would have been absorbed by the gas giant, eventually forming the dense core of the planet. Then, scientists believe that Jupiter began to absorb and collect gas from the birth of our Sun. This is what helped form the clouds that we see covering the surface of the planet now, too.

Of course, even with this evidence, we can’t say for sure how Jupiter formed. It is possible that Jupiter ate smaller planets as it was forming. But, with no way to see the planet itself form, we can’t verify that this happened. All we can do now is interpret the evidence we’ve discovered. And right now, that evidence says Jupiter is a planet eater.
