Human Chromosomes Are Only Half DNA, And That Changes Everything

For a long time, scientists thought that DNA was the only thing inside your chromosomes. A new study turns that assumption on its head.

Have you ever stopped to think about how impressive it is that dogs can understand so much of what we say to them? It's a rare housecat that will roll over or play fetch on command, but getting a puppy to do that just takes only a few training sessions. But according to research, dogs' ability to understand humans goes even deeper than you probably realize.

A Baby Was Born With The DNA Of 3 People

It's possible to have more than two parents these days. Not just legally speaking, but at a genetic level too. It's actually been possible for a baby to be born with the DNA of three parents since the 1990s, but the concept took an unprecedented step in September 2016, when the first baby with the DNA of three parents was born using a new technique called mitochondrial donation. Thanks to this revolutionary method, the baby doesn't have Leigh Syndrome, a genetic condition that was present in the mother's genes (this technique can be used to avoid a number of genetic conditions). This is huge and exciting news for science, but, of course, it doesn't come without controversy.

Can Meditation Affect Your DNA Makeup?

Meditation has been proven to positively affect hypertension, anxiety, insomnia, PTSD, traumatic brain injury, and more in people. But new research suggests that meditating can affect the very makeup of your DNA. A recent study held by a Canadian research team looked at different groups of distressed breast cancer patients. Each group went through varying amounts of group therapy, yoga, and meditation sessions. The groups that went through yoga, meditative mindfulness practices, and group therapy had their telomeres in tact. Telomeres are stretches of DNA that act as caps on our chromosomes, and help prevent deterioration of chromosomes. Shortened telomeres are not likened to any specific disease, but we do know that they shorten with age.

DNA Is The Long-Term Digital Storage Solution Of The Future

DNA has been a powerful and effective storage medium for life on Earth for millions of years. But what if researchers could harness this storage power for all of humanity's information? Molecular Biologist Nick Goldman and his team at the European Bioinformatics Institute have created a way to do just that. According to Goldman, all the information in the world could be encoded and stored in DNA, and it would fit in the back of a SUV and last millions of years. The results from experimenting with DNA as data storage suggest that data in DNA form could last 2,000 years if kept at a temperature of around 10°C. The DNA storage could be preserved for over 2 million years if stored at a -18 °C.
