Aging. We all face it. Nobody’s immune and we’ve long tried to reverse it, stop it or just even slow it down. While advances have been made, true age-reversal at a cellular level remains difficult to achieve. By taking a different approach, however, researchers at Houston Methodist made a surprising discovery leading to the development of technology with the ability to rejuvenate human cells. And that couldn’t be more important for the small population of children who are aging too quickly — children with progeria.

John P. Cooke, M.D., Ph.D., department chair of cardiovascular sciences at Houston Methodist Research Institute, and his colleagues, describe their findings in a Research Letter titled “Telomerase mRNA Reverses Senescence in Progeria Cells,” appearing online July 31 and in print Aug. 8 in the Journal of the American College of Cardiology, a leading medical journal in the field of cardiovascular disease.

Cooke studied cells from children with progeria, a rare condition marked by rapid aging that usually robs them of the chance to live beyond their early teens. They focused on progeria, because the condition tells them a lot about aging in general that’s ultimately relevant to all of us.

Of all the topics I’ve written about, this one scares me the most.

Yes, artificial intelligence, one of humanity’s greatest achievements, can also unleash the seeds of our own destruction. Weaponized A.I. will range from relatively minor weapons designed to change a specific action to nation-vs-nation full-blown A.I. wars.

We think there is a real signal there and this implies an additional planet.

John Bucknell presented at the Starship Congress 2017 his Nuclear Thermal Turbo Rocket and applied for a single stage to orbit mission of placing a space habitat. John Bucknell worked on the SpaceX Raptor rocket as a senior engineer so he is very qualified to understand current rocket technology and rockets in general.

Nextbigfuture has noted that NASA has funded $18.8 million on advancing nuclear thermal rocket propulsion by studying low enriched uranium for the fuel. Nuclear-powered rocket concepts are not new. The United States conducted studies and significant ground tests from 1955 to 1972 to determine the viability of such systems, but ceased testing when plans for a crewed Mars mission were deferred.

The NERVA NRX (Nuclear Rocket Experimental) program started testing in September 1964. The final engine in this series was the XE, designed with flight design hardware and fired in a downward position into a low-pressure chamber to simulate a vacuum. SNPO fired NERVA NRX/XE twenty-eight times in March 1968. The series all generated 1100 MW, and many of the tests concluded only when the test-stand ran out of hydrogen propellant. NERVA NRX/XE produced the baseline 75,000 lbf (334 kN) thrust that Marshall required in Mars mission plans.

LONDON (Reuters) — The risk of cyber attacks targeting ships’ satellite navigation is pushing nations to delve back through history and develop back-up systems with roots in World War Two radio technology.

Ships use GPS (Global Positioning System) and other similar devices that rely on sending and receiving satellite signals, which many experts say are vulnerable to jamming by hackers.

About 90 percent of world trade is transported by sea and the stakes are high in increasingly crowded shipping lanes. Unlike aircraft, ships lack a back-up navigation system and if their GPS ceases to function, they risk running aground or colliding with other vessels.

A proposal in Congress would create the first new uniformed service in 70 years, but it faces opposition from the Pentagon.

The U.S. military hasn’t added a new uniformed service in 70 years, when the Air Force was created in the aftermath of World War II.

If Congress gets its way, that will soon change.

The future of cancer care should mean more cost-effective treatments, a greater focus on prevention, and a new mindset: A Surgical Oncologist’s take

Multidisciplinary team management of many types of cancer has led to significant improvements in median and overall survival. Unfortunately, there are still other cancers which we have impacted little. In patients with pancreatic adenocarcinoma and hepatocellular cancer, we have been able to improve median survival only by a matter of a few months, and at a cost of toxicity associated with the treatments. From the point of view of a surgical oncologist, I believe there will be rapid advances over the next several decades.

Robotic Surgery

There is already one surgery robot system on the market and another will soon be available. The advances in robotics and imaging have allowed for improved 3-dimensional spacial recognition of anatomy, and the range of movement of instruments will continue to improve. Real-time haptic feedback may become possible with enhanced neural network systems. It is already possible to perform some operations with greater facility, such as very low sphincter-sparing operations for rectal adenocarcinoma in patients who previously would have required a permanent colostomy. As surgeons’ ability and experience with new robotic equipment becomes greater, the number and types of operation performed will increase and patient recovery time, length of hospital stay, and return to full functional status will improve. Competition may drive down the exorbitant cost of current equipment.
