Cosmic uncertainty: Is the speed of light really constant?

Posted by in category: futurism

The universe’s ultimate speed limit seems set in stone. But there’s good reason to believe it might once have been faster – and may still be changing now.

By Stuart Clark

The speed of light in a vacuum is the ultimate cosmic speed limit. Just getting close to it causes problems: the weird distortions of Einstein’s relativity kick in, so time slows down, lengths go up, masses balloon and everything you thought was fixed changes. Only things that have no mass in the first place can reach light speed – photons of light being the classic example. Absolutely nothing can exceed this cosmic max.

The Alzheimer’s Hypothesis

Posted by in categories: biotech/medical, neuroscience

A detailed analysis of Alzheimer’s disease.


Alzheimer’s disease was first discovered in 1907 in a 51 year old woman by the German physician Alzheimer. One of the first changes noticed was an eruption of jealous feelings towards her husband. It wasn’t long before symptoms of rapid memory impairment were observed. The impairments prevented her from finding her way out of her home, She hid herself, she would drag objects to and fro, and occasionally screamed because she believed people were out to kill her.

When she was institutionalized her gestures would show a complete helplessness. As common in most Alzheimer’s patients, she was disoriented as to time and place. At times she would state that she didn’t understand anything, felt confused, and totally lost. When the doctor came in to see her she would consider it as an official visit and would apologize for not having finished her work. Other times she would be terrified and start to yell that the doctor wanted to operate on her. Other times she would send him away in complete indignation uttering phrases indicating that she was afraid that the doctor wanted to damage her woman’s honor. At times she would become completely delirious, dragging her blankets and to and fro, calling for her husband and daughter, and seeming to experience auditory hallucinations. She would often scream for hours and hours in a horrible voice. Mental regression advanced quite steadily. After four and a half years of illness the patient finally died.

Ocean Cleanup steams out to sea in test run to clean Great Pacific Garbage Patch

Posted by in categories: materials, sustainability

If all goes well, it will be towed out to the Great Pacific Garbage Patch nearly 1,400 miles off the West Coast, about halfway between California and Hawaii. A support vessel will fish out the collected plastic every few weeks, according to the Associated Press. The waste will then be transported to dry land for recycling.

Shipping containers filled with the collected plastic are expected back on land within a year.

The project is lauded by many as a positive attempt to deal with the growing problem of plastic pollution in the oceans.

Methuselah Foundation Cofounder thinks Longevity Escape Velocity could be here by 2030

Posted by in categories: biotech/medical, life extension

David Gobel was the first to put forward the concept of longevity escape velocity, or LEV. How far are we from LEV, assuming the current pace of research and no serious showstoppers?

Twelve years, or 2030, is David’s best guess based on what is known today.


David Gobel cofounded the Methuselah Foundation with Aubrey de Grey and continues to run the Methuselah Foundation today.
