The Problem With “The Rare Earth Hypothesis”

Posted by in categories: alien life, media & arts

The Rare Earth Hypothesis suggests that our planet may the product of an incredibly improbable sequence of events, and thus perhaps intelligent life is extremely rare in the cosmos. Here we tackle this highly influential idea and the arguments behind it. But, digging deeper, we’ll uncover some problems with the Rare Earth idea — some of which strike to the very core of our scientific quest.

Written & presented by Prof David Kipping.

In the underground movement known as, people are taking their health into their own hands. Biohacking ranges from people making simple lifestyle changes to extreme body modifications.

One popular form of focuses on nutrigenomics, where biohackers study how the foods they eat affect their genes over time. They believe they can map and track the way their diet affects genetic function. They use dietary restrictions and blood tests, while tracking their moods, energy levels, behaviors, and cognitive abilities.

Unmasking BACE1 in aging and age-related diseases

Posted by in categories: biotech/medical, life extension, neuroscience

The BACE1 enzyme has a rate-limiting role in the amyloidogenic pathway (see Glossary) and has been extensively studied for its neuronal functions[1]. Since 2000, intensive efforts have focused on developing small-molecule BACE1 inhibitors to reduce amyloid β (Aβ) production in Alzheimer’s disease (AD) brains. However, human clinical trials involving most BACE1 inhibitors were stopped at Phase 2/3 due to limited therapeutic benefits[2]. BACE1 inhibitors act by reducing Aβ-related pathologies in AD brains, that is, they are used to treat the symptoms rather than the underlying disease.

China Maps Out Plans to Put Astronauts on the Moon and on Mars

Posted by in categories: mapping, space

While grand spaceflight plans of some nations have ended up many years behind schedule, China completed the assembly in orbit of its Tiangong space station in late October, only 22 months later than planned. And on Nov. 29, the Shenzhou 15 mission blasted off from China’s Jiuquan Satellite Launch Center deep in the Gobi Desert and took three astronauts to the space station to begin permanent occupancy of the outpost.

These human spaceflight achievements, combined with recent space probes to the moon and Mars, add to the evidence that China is running a steady space marathon rather than competing in a head-to-head space race with the United States. That China’s space program is making good time toward its long-term goals was reinforced during a rare visit for foreign media to the country’s heavily guarded desert rocket base for the Nov. 29 launch — including lengthy interviews with senior Chinese space officials by in for The New York Times.
