A new study from Washington University School of Medicine in St. Louis suggests that bone marrow — or blood stem cells — from healthy donors can harbor extremely rare mutations that can cause health problems for the cancer patients who receive them.


A stem cell transplant — also called a bone marrow transplant — is a common treatment for blood cancers, such as acute myeloid leukemia (AML). Such treatment can cure blood cancers but also can lead to life-threatening complications, including heart problems and graft-versus-host disease, in which new immune cells from the donor attack a patient’s healthy tissues.

A new study from Washington University School of Medicine in St. Louis suggests that extremely rare, harmful genetic mutations present in healthy donors’ stem cells — though not causing health problems in the donors — may be passed on to cancer patients receiving stem cell transplants. The intense chemo- and radiation therapy prior to transplant and the immunosuppression given after allow cells with these rare mutations the opportunity to quickly replicate, potentially creating health problems for the patients who receive them, suggests the research, published Jan. 15 in the journal Science Translational Medicine.

Among the concerns are heart damage, graft-versus-host disease and possible new leukemias.

BREAKING: We’ve confirmed that the Ring doorbell app on Android covertly shares personally identifiable information on its users with third-party companies, including Facebook… Information delivered to Facebook (even if you don’t have a Facebook account)


Ring isn’t just a product that allows users to surveil their neighbors. The company also uses it to surveil its customers.

An investigation by EFF of the Ring doorbell app for Android found it to be packed with third-party trackers sending out a plethora of customers’ personally identifiable information (PII). Four main analytics and marketing companies were discovered to be receiving information such as the names, private IP addresses, mobile network carriers, persistent identifiers, and sensor data on the devices of paying customers.

The danger in sending even small bits of information is that analytics and tracking companies are able to combine these bits together to form a unique picture of the user’s device. This cohesive whole represents a fingerprint that follows the user as they interact with other apps and use their device, in essence providing trackers the ability to spy on what a user is doing in their digital lives and when they are doing it. All this takes place without meaningful user notification or consent and, in most cases, no way to mitigate the damage done. Even when this information is not misused and employed for precisely its stated purpose (in most cases marketing), this can lead to a whole host of social ills.

Europe’s Galileo satellite navigation system can now not only receive, relay, and locate distress beacon signals, it can also respond to the SOS, sending back an acknowledgement to those awaiting rescue that their location and call for help has been received and search and rescue services are responding. The new function became operational during the 12th European Space Conference in Brussels, which ran from January 21 to 22, 2020.

Global Navigation Satellite Systems (GNSS) have come a long way since the US Military introduced the first, Transit, in the 1960s. The technology not only revolutionized navigation to the point where anyone with a smartphone can pinpoint their location with the touch of an icon, but it’s also having an increasing impact as more functions are added to that of basic navigation.

Today, there are four global satellite navigation systems and Galileo is a key part of the Cospas-Sarsat system founded in 1979 by Canada, France, Russia, and the US, with 24 out of the 26 Galileo satellites carrying an 8-kg (18-lb) search and rescue package next to the main antenna. According to ESA, the ability of the Galileo satellite constellation to receive and relay SOS signals saves up to 2,000 lives per year.

LOS ANGELES, Jan. 27, 2020 /PRNewswire/ — Yates Electrospace Corporation (YEC), whose Silent Arrow platform is bringing disruptive innovation to the heavy payload, unmanned cargo delivery market, today announced the design completion and specifications of a wide-body version of its successful GD-2000 cargo delivery drone, with unveiling set for July 20–24, 2020 at YEC booth 4470, Farnborough International Airshow, UK.

Three and a half hours later, the group finished the simulation exercise — and despite their best efforts, they couldn’t prevent the hypothetical coronavirus from killing 65 million people.

The fictional coronavirus at the center of the Event 201 simulation — a collaboration between the Johns Hopkins Center for Health Security, the World Economic Forum, and the Bill and Melinda Gates Foundation — was called CAPS, and it started with pigs in Brazil before spreading to farmers, not unlike how 2019-nCoV reportedly began with animals before spreading to people.

In the simulation, CAPS infected people all across the globe within six months, and by the 18-month mark, it had killed 65 million people and triggered a global financial crisis.

Chip Walter discusses his book, “Immortality, Inc”, at Politics and Prose.

Living forever has always been a dream, but with today’s science, technology, and visionary billionaires, it may be a distinct possibility. At the very least, as Walter reports in this compelling investigation, immortality researchers are changing the way we view aging and death. Looking at the science, business, and culture of this radical endeavor, Walter, a science journalist, author of Last Ape Standing, and former CNN bureau chief, lays out the latest research into stem cell rejuvenation, advanced genomics, and artificial intelligence; talks to key thinkers such as Ray Kurzweil and Aubrey de Grey; and takes us into the Silicon Valley labs of human genomics trailblazer Craig Venter and molecular biologist and Apple chairman Arthur Levinson. Walter is in conversation with Hilary Black, executive editor at National Geographic Books.
