The countdown to the arrival of quantum computing has already begun. Here’s how the government can get ready.

What is less known is that a more problematic source of DNA damage is normal cellular processes such as DNA replication. These cannot be avoided because they are inevitably in action every time cells divide. The scale of this problem is best illustrated by realizing that our bodies are made up by successive divisions of trillions of cells, all originating from a single fertilized egg. Every day, a quarter of a trillion cells in the adult human body continue to divide to replenish old or damaged tissue. Amongst the multitude of DNA damage incurred during each such cell division process, the most dangerous are those that can be passed on from mother cells to newly born daughter cells. This inherited DNA damage is the true ‘enemy within’ that cannot be simply avoided by changing one’s lifestyle.
Researchers from the University of Copenhagen have identified a specific mechanism that protects our cells from natural DNA errors — an ‘enemy within’ — which could permanently damage our genetic code and lead to diseases such as cancer. The study has just been published in one of the most influential scientific journals, Nature Cell Biology.
Researchers from the University of Copenhagen have discovered a mechanism that gives human cells a chance to stop piling up mutations cells replicate and divide in the body. The discovery could prove to be very useful in the development of new treatments against diseases caused by changes in human DNA such as cancer.
To limit harmful changes in the genetic code that may lead to potential diseases, the cells in our body rely on a natural defense mechanism. The new study shows how specialized proteins engulf and protect the damaged DNA and ‘escort’ it until the damage can be repaired. The researchers discovered that this process relies on precise timing and meticulous control inside the cells.
The Air Force had said there was about a 20% chance that the launch would be delayed because of bad weather. But the 23-story Falcon 9 rocket lifted off on time on Thursday.
After the booster’s landing, SpaceX CEO Elon Musk tweeted: “Highest reentry heating to date. Burning metal sparks from base heat shield visible in landing video.”
You can watch the mission and landing, narrated by SpaceX staff, here, though this clip shows the booster’s heat shield burning off.

NEW HAVEN, Conn. (AP) — Bacteria lodged deep in Ella Balasa’s lungs were impervious to most antibiotics. At 26, gasping for breath, she sought out a dramatic experiment — deliberately inhaling a virus culled from sewage to attack her superbug.
“I’m really running out of options,” said Balasa, who traveled from her Richmond, Virginia, home to Yale University for the last-resort treatment. “I know it might not have an effect. But I am very hopeful.”
Pitting one germ against another may sound radical, but it’s a sign of a growing global crisis. Increasingly people are dying of infections that once were easy to treat because many common bugs have evolved to withstand multiple antibiotics. Some, dubbed “nightmare bacteria,” are untreatable. Now scientists are racing to find novel alternatives to traditional antibiotics, a hunt that is uncovering unusual ways to counter infection, in unusual places.

It’s finally happening. Nearly 8 years after the final space shuttle flight, a crew-capable spacecraft is once again ready to launch from Kennedy Space Center, Florida. SpaceX’s Crew Dragon is scheduled to blast off for a 6-day, uncrewed test flight on 2 March at 02:49 EST (07:49 UTC). If all goes well, the spacecraft will dock at the International Space Station (ISS) on 3 March around 06:00 EST (11:00 UTC) and stay there until 8 March, when it returns to Earth and splashes down in the Atlantic Ocean off the Florida coast.

Many major advances in medicine, especially in neurology, have been sparked by recent advances in electronic systems that can acquire, process, and interact with biological substrates. These bioelectronic systems, which are increasingly used to understand dynamic living organisms and to treat human disease, require devices that can record body signals, process them, detect patterns, and deliver electrical or chemical stimulation to address problems.

Bill Faloon is the co-founder of the Life Extension nutritional supplement company and founder of the Church of Perpetual Life in Hollywood, Florida.
Bill was at the Raadfest 2018, which is an antiaging conference which had an attendance of about 1000 people. Bill is like others who attend Raadfest who want to take any antiaging treatment which has some scientific evidence of effectiveness. There is the possibility that latest antiaging treatments could work and the early adopters might be able to improve their health and life 0 to 20 years longer.
There are risks and costs with this approach. On the other hand, $140 billion per year is spent on cosmetics, vitamins and other treatments which have no evidence of life extending properties. Vitamins tend to have a lot of scientific evidence of ineffectiveness.
