“Aging is a consequence of physics, not biology.” Dr. Aubrey de Grey believes that the aging of any machine with moving parents is fundamentally the same, whether that machine is alive or not. He states that the SENS Foundation doesn’t work on longevity and immortality — it works on health. “The only way we are going to live substantially longer is by staying truly youthful for substantially longer.”
An epidemiological survey has found there were about 400 million patients needing new teeth in China, but the number of qualified dentists was lagging behind demand.
In March this year the US Food and Drug Administration approved the use of a robot system named Yomi designed to assist human surgeons when fitting implants.
Successful procedure raises hopes technology could avoid problems caused by human error and help overcome shortage of qualified dentists.

Microsoft’s first mission statement envisioned a computer on every desk and in every home, but Bill Gates also had another goal: that computers would someday be able to see, hear, communicate and understand humans and their environment.
More than 25 years and two CEOs later, Microsoft is betting its future on it.
The immune system is like an army keeping us safe from invasion, injury and infection and helps us to regenerate and repair tissues and organs. However, the immune system is sometimes a double-edged sword that does more harm than good.
A lot of focus has been on the role of macrophages and their ability to facilitate tissue healing and regeneration. Today, we will be looking at a study that examines the role of neutrophils and how they can actually harm the brain further following a stroke[1].

Ed Whiting, director of policy at the Wellcome Trust agreed and said: “There is no doubt of the urgency – the world is running out of effective antibiotics and drug-resistant infections already kill 700,000 people a year globally. We’ve made good progress in getting this on the political agenda. But now, a year on from a major UN agreement, we must see concerted action – to reinvigorate the antibiotic pipeline, ensure responsible use of existing antibiotics, and address this threat across human, animal and environmental health.”
The report’s authors have found 51 new antibiotics and biologicals currently in development that may be able to treat the diseases caused by these resistant bugs. But that will not be anywhere near enough because of the length of time it takes to get drugs approved and onto the market, and because inevitably some of the drugs will not work.
“Given the average success rates and development times in the past, the current pipeline of antibiotics and biologicals could lead to around 10 new approvals over the next five years,” says the report. “However, these new treatments will add little to the already existing arsenal and will not be sufficient to tackle the impending antimicrobial resistance threat.”
ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests as the company moves towards installing the engine in its Demonstrator 3 rocket. Designed to power the world’s first operational Single-Stage-To-Orbit (SSTO) satellite launcher, the engine took only 60 days to complete from when fabrication began.
Over the past 60 years, space launches have become pretty routine. The first stage ignites, the rocket lifts slowly and majestically from the launch pad before picking up speed and vanishing into the blue. Minutes later, the first stage shuts down and separates from the upper stages, which ignite and burn in turn until the payload is delivered into orbit.
This approach was adopted not only because it provides enough fuel to lift the payload while conserving weight, but also because the first-stage engines, which work best at sea level, are very inefficient at higher altitudes or in space, so different engines need to be employed for each stage of flight.
