On/off button for passing along epigenetic ‘memories’ to our children discovered

Posted by in categories: biotech/medical, genetics

The duration of epigenetic responses underpinning transgenerational inheritance is determined by an active mechanism relying on the production of small RNAs and modulation of RNAi factors, dictating whether ancestral RNAi responses would be memorized or forgotten (credit: Leah Houri-Ze’evi et al./Cell)

According to epigenetics — the study of inheritable changes in gene expression not directly coded in our DNA — our life experiences may be passed on to our children and our children’s children. Studies on survivors of traumatic events have suggested that exposure to stress may indeed have lasting effects on subsequent generations.

But exactly how are these genetic “memories” passed on?

5 Questions For E.T

Posted by in category: alien life

Kind of a light-hearted end of week meditation on what questions we might first pose to an extraterrestrial intelligence, if they were willing to sit for an interstellar town hall. Hope you enjoy.


If extraterrestrial (E.T.) intelligent civilizations are out there, given the age of the cosmos they stand a chance of being millions, or even billions of years ahead of us in almost every way. Assuming that we were even able to start a cosmic dialogue with them, I’ve often wondered what humanity should first ask such an advanced civilization.

Here are five sample questions:

Boeing CST-100: Next-Generation Spaceship

Posted by in category: space travel

The Boeing Co. is one of two companies funded by NASA to develop spacecraft for the International Space Station. Its CST-100 Starliner is expected to fly with an astronaut on board no earlier than 2017.

The firm is best known for its large passenger jets. In space, it has performed work on the space shuttle and the ISS, among other projects.

The CST-100 is similar in shape to the Apollo spacecraft, but should have electronics that are half a century more advanced. Its gumdrop shape also looks somewhat like the Orion Crew Exploration Vehicle being constructed right now by Lockheed Martin and its partners. Orion is designed to carry astronauts beyond low Earth orbit.

Could ‘Planet X’ Cause Comet Catastrophes on Earth?

Posted by in categories: asteroid/comet impacts, existential risks

As astronomers track down more clues as to the existence of a large world orbiting the sun in the outer fringes of the solar system, a classic planetary purveyor of doom has been resurrected as a possible trigger behind mass extinctions on Earth.

Yes, I’m talking about “Planet X.” And yes, there’s going to be hype.

Science has discovered hell

Posted by in categories: science, space

Hell has an address: 55 Cancri-e is the first alien planet to have some of its surface features directly observed. And it’s no tropical paradise.

For some time 55 Cancri-e has been considered “strange.” Some felt it may be made of diamond. Others suggested it was covered in exotic fluids.

International ‘Moon Village’ Is Way To Go According To European Space Agency | Video

Posted by in categories: 3D printing, business, robotics/AI, space

Sounds great — as long as we don’t call it a Moon Village. That sounds inane.


The director general of ESA, Johann-Dietrich Woerner, believes that the world should collaborate to create a permanent lunar base for “science, business, tourism or even mining.” Plans to use robotics and 3D printing for building the base have been discussed.

A Wannabe Supervillain Built His Own Thermite Cannon

Posted by in categories: energy, entertainment

It’s not often you come across a real-life mad scientist. They’re usually just over-the-top antagonists in comic books, but Colin Furze is the real thing. He has a penchant for building things that often blow up—on purpose—like this impossibly dangerous-looking thermite cannon.

Not familiar with thermite? It’s an especially nasty chemical composition made of metal power and oxide that burns as hot as 2,500 degrees celsius. If it ignites, you don’t want to be anywhere near it, which is why a cannon that puts a lot of distance between you and a flaming thermite grenade isn’t the world’s worst idea.
