Brian Cox says we’ll soon upload our brains onto computers
It may sound like the plot from the latest science fiction blockbuster, but uploading your brain onto a computer to achieve immortality could soon become a reality.
In a new interview, Professor Brian Cox said that the technique, known as ‘technological singularity’ could be available sooner than you think.
Professor Cox said that he found ‘no reason at all’ why human intelligence couldn’t be simulated by computers — although he did not express a timeline for this to happen.
The Brain’s Meninges Harbour its Lymphatic System
By scanning the brains of healthy volunteers, researchers at the National Institutes of Health saw the first, long-sought evidence that our brains may drain some waste out through lymphatic vessels, the body’s sewer system. The results further suggest the vessels could act as a pipeline between the brain and the immune system.
Dr. Daniel S. Reich, Ph.D., M.D., discusses how his team discovered that our brains may drain waste through lymphatic vessels, the body’s sewer system.
To Combat Radical Violence in America, We Need Radical Medicine
With yesterday’s terrible shooting tragedy, I’m hearing lots of calls for more gun control to reduce violence in the US. But that’s essentially impossible to accomplish. There are 300 million guns in America. Congress faces a statistical impossibility to make a real dent in gun control and possession (politicians saying otherwise are playing you for votes—the gov is not going to go house to house to collect guns). HOWEVER, better ways to combat terrorism and gun violence could be achieved through better medicine and figuring out better ways to keep wounded peope alive. We should focus our energy and science money on treating trauma victims (and also on prevention of mental disease and sociopaths). Also, drones can be designed to seek out shooters in public places in 30 seconds and stop what they’re doing (instead of letting them shoot for 10 minutes). Why don’t major public venues and events have them yet? Ask you government? Demand better responses so our society is safer. Also, entreprenuers, get out there and do something about this. Hotels would pay big money for see-through-wall technology that would alert staff that someone has 20 weapons in a room. Lots of this tech is already here. All these terrorism and gun violence issues can be best figured out by tech and science. Stop sending prayers, and instead send some engineers and technologists to solve the problems. This tragic ongoing violence will continue until tech and science solves it.
“If you make the human body virtually indestructible, being wounded loses some of its relevance.”
America is reeling in shock from multiple shooting tragedies. The national feeling is that the violence is increasing in frequency and there’s no end to the angst.
In the last few weeks, we’ve experienced tragic episodes in Dallas, Minnesota, Baton Rouge, and Orlando. Politicians have decried the events, calling on Congress to do more about gun control, police responsibility, and racism.
While I passionately support policies that would make Americans safer and diffuse racism, I don’t think people are going to change anytime soon. However, there is something that could significantly change our national security regardless of what tragedy strikes: far better trauma medicine.
Meet the Extensionists: People Who Believe Immortality Is Possible
Leading women’s magazine Marie Claire has a feature story on life extension out this month (approx 1.5 million circulation):
Forget about life after death. More and more, women around the country are seeking another kind of miracle: not dying at all.
What if you could hit the pause button on aging? Live to 120 without feeling a day over 80? More radical still, what if you could cheat death? Would you do it?
“Life extensionists” would. That’s the name modern immortality seekers now go by, and devotees range from those who’d like to live healthier lives into old age to the more extreme, who ardently believe that humans can, and should, overcome death the same way we’ve overcome, say, smallpox or tooth decay.
Life expectancy for women in the United States has risen steadily from 73 in the 1960s to 81 today, with those numbers continuing to increase thanks to a combination of biology and higher standards of living (not to mention the over 1,000 geneticists and biologists working in the longevity field). But life extensionists want more. They want to be cognitively and physically healthy for decades, if not centuries.
Freezing People After Heart Attacks Could Save Lives
To reduce the damage to his brain and organs, Brooks was rushed to the University of Pennsylvania, where Dr. Lance Becker and his team cooled the young man’s core temperature to below 90 degrees Fahrenheit—a process called “induced hypothermia.” This is often done to cardiac arrest patients, either by injecting them with a cold saline solution or placing ice packs on them to increase their chances of complete recovery.
The dose of cold saved his life. Brooks had no brain damage, a remarkable feat that has led doctors to explore more ways to use induced hypothermia in emergency settings.
Now Dr. Sam Tisherman and his team at the University of Maryland, in collaboration with the University of Pittsburgh, plan to put 10 patients into a more severe form of hypothermia than what Brooks got, something known as “suspended animation.” They’ll flush their bodies with a cold fluid, cooling (and therefore preserving) tissue. The experimental trial, known as emergency preservation and resuscitation for cardiac arrest from trauma ( EPR-CAT), is funded by the U.S. Department of Defense, and it is the first time doctors are harnessing profound hypothermia (pushing body temperatures to as low as 50 degrees) to save lives.
Study shows how ‘love hormone’ oxytocin spurs sociability
Why is it so much fun to hang out with our friends? Why are some people so sociable while others are loners or seemingly outright allergic to interactions with others?
A new study by researchers at the Stanford University School of Medicine begins to provide an answer, pinpointing places and processes in the brain that promote socialization by providing pleasurable sensations when it occurs. The findings point to potential ways of helping people, such as those with autism or schizophrenia, who can be painfully averse to socializing.
The study, which will be published Sept. 29 in Science, details the role of a substance called oxytocin in fostering and maintaining sociability. The senior author is Robert Malenka, MD, PhD, professor and associate chair of psychiatry and behavioral science. The lead author is former postdoctoral scholar Lin Hung, PhD.
