Solar Storm Could Do $2 Trillion in Damage

I read an interesting article from NASA recently, Near Miss: The Solar Superstorm of July 2012

According to a study by the National Academy of Sciences, the total economic impact could exceed $2 trillion or 20 times greater than the costs of a Hurricane Katrina. Multi-ton transformers damaged by such a storm might take years to repair.

By extrapolating the frequency of ordinary storms to the extreme, he calculated the odds that a Carrington-class storm would hit Earth in the next ten years.

The answer: 12%.

Our high technology is far more at risk than most people appreciate. I don’t understand why the odds are so high (given that the last such event was in 1859 but I would guess there are sensible reasons for them to calculate such high odds. Others (in a quick web search) offer lower odds, but still 7 or 8% of such an event in the next 10 years.

The 2012 event would have done a great deal of damage. Luckily it was directed away from the sun in a direction away from where the earth was at the time. NASA has satellites arrayed around the sun (even where the earth isn’t) and one of those was able to capture data on the event.

There is also disagreement about how much damage such a solar storm would cause on earth. The main direct damage is expected to be done to the power system (of the USA and the rest of the world).

Female African-American Mathematicians at NASA in 1961

Hidden Figures is a film based on the experiences of female African-American mathematicians at NASA in 1961 including Katherine Johnson. It is easy to forget our history if we don’t make an effort to remember.

Popular movie adaptations are not the best source for completely accurate history but they are a great way to raise awareness when they hold somewhat close to historical events.

It is amazing to see what was accomplished and also remember how badly mistaken our society was in important ways. We have made strides as a society, but we still have significant problems we need to address. Movies like Hidden Figures are a positive reminder of what can be accomplished when we give people opportunities. We need to remember that lesson and do what we can to remove the barriers that continue today.

14 Year Old Signs $700,000 MOU for a Drone to Detect and Defuse Land Mines

Harshwardhan Zala, from Gujarat, India has signed an agreement worth Rs. 5 crore (US$733,940) to explore the possibility of commercial production of a drone created by him which can help in detecting and defusing landmines.

Harshwardhan started work on the prototype of the landmine-detecting drone last year after reading in newspapers about high army casualties due to landmines. Aerobotics7 is the company founded by the 14 years old.

Harshwardhan Zala, 14-year-old trends for Rs 5 crore deal at Vibrant Gujarat Global Summit 2017!

Explaining more about the drone, the zealous 14-year-old said, “The drone is designed to send out waves that cover eight sq. mt area while flying two feet above the surface; the waves detect land mines and communicate their location with a base station. The drone also carries a bomb weighing 50 gram that can be used to destroy the landmine.” Harshwardhan Zala’s proud father Pradhyumansinh is an accountant with a plastic company in Naroda, and his mother Nishaba is a homemaker.

[missing video – removed 🙁 ]

The video has Harshwardhan speaking a bit of English but mainly some other language that I don’t understand. If I understand right, his drone is 98% accurate at identifying mines (where the current solutions are 92% accurate – and much more dangerous for those having to walk around testing). His solution is 17 times faster and 22 times cheaper than the current solutions. Once the mine is detected by the drone through an infrared sensor, a 50 gram detonator will complete the task of defusing it (blowing it up).

This video shows a bit of the drone itself (non-English audio)

Unexpected Risks Found In Editing Genes To Prevent Inherited Disorders

Mitochondrial replacement seeks to remove genes known to cause genetic defects from embryos in order to allow for a baby to avoid inheriting the defect.

Mitochondrial Replacement Techniques: Ethical, Social, and Policy Considerations from the USA National Academy of Sciences

Accordingly, the committee recommends that any initial MRT clinical investigations focus on minimizing the future child’s exposure to risk while ascertaining the safety and efficacy of the techniques. The recommended restrictions and conditions for initial clinical investigations include

  • limiting clinical investigations to women who are otherwise at risk of transmitting a serious mtDNA disease, where the mutation’s pathogenicity is undisputed, and the clinical presentation of the disease is predicted to be severe, as characterized by early mortality or substantial impairment of basic function; and
  • transferring only male embryos for gestation to avoid introducing heritable genetic modification during initial clinical investigations.

Following successful initial investigations of MRT in males, the committee recommends that FDA could consider extending MRT research to include the transfer of female embryos if clear evidence of safety and efficacy from male cohorts, using identical MRT procedures, were available, regardless of how long it took to collect this evidence; preclinical research in animals had shown evidence of intergenerational safety and efficacy; and FDA’s decisions were consistent with the outcomes of public and scientific deliberations to establish a shared framework concerning the acceptability of and moral limits on heritable genetic modification.

The research in this area is interesting and our ability to help achieve healthy lives continues to grow. The path to a bright future though is not without risk. It requires careful action to pursue breakthrough improvements while minimizing the risks we take to achieve better lives for us all.

Unexpected Risks Found In Editing Genes To Prevent Inherited Disorders

Earlier this month, a study published in Nature by Shoukhrat Mitalipov, head of the Center for Embryonic Cell and Gene Therapy at the Oregon Health and Science University in Portland, suggested that in roughly 15 percent of cases, the mitochondrial replacement could fail and allow fatal defects to return, or even increase a child’s vulnerability to new ailments.

The findings confirmed the suspicions of many researchers, and the conclusions drawn by Mitalipov and his team were unequivocal: The potential for conflicts between transplanted and original mitochondrial genomes is real, and more sophisticated matching of donor and recipient eggs — pairing mothers whose mitochondria share genetic similarities, for example — is needed to avoid potential tragedies.

“This study shows the potential as well as the risks of gene therapy in the germline,” Mitalipov says. This is especially true of mitochondria, because its genomes are so different than the genomes in the nucleus of cells. Slight variations between mitochondrial genomes, he adds, “turn out to matter a great deal.”

US Fish and Wildlife Service Plans to Use Drones to Drop Vaccine Treats to Save Ferrets

Despite significant recovery successes, the black-footed ferret remains one of the most endangered animals in the world.

The U.S. Fish and Wildlife Service has developed a plan to use (UAS) to deliver prairie dog sylvatic plague vaccination.

The primary purpose in this proposal is to develop the equipment, protocols and experience in use of UAS (drones) to deliver oral sylvatic plague vaccine (SPV). It is anticipated that this approach, when fully developed, will offer the most efficient, effective, cost-conscious and environmentally friendly method to apply SPV annually over large areas of prairie dog colonies in support of black-footed ferret recovery.

Plague is a primary obstacle to black-footed ferret recovery. After more than 20 years of intensive reintroduction efforts across 27 reintroduction sites ranging from Mexico to Canada, approximately 300 ferrets were known to exist in the wild at the end of 2015. Ferrets are constantly threatened by plague outbreaks that affect both ferrets, and their primary prey and habitat provider, prairie dogs.

To date, SPV has been applied by hand with people walking pre-defined transects and uniformly dropping single SPV baits every 9-10 meters to achieve a deposition rate of 50 SPV doses per acre. Depending on vegetation and terrain, a single person walking can treat 3-6 acres per hour. All terrain vehicles (ATVs) have been considered but have various problems.

The bait treats are M&Ms smeared in vaccine-laden peanut butter.

Preliminary discussions with people experienced with UAS suggest an aerial vehicle travelling at a modest 9 meters per second could drop a single SPV bait once per second that would result in treating one acre every 50 seconds. If the equipment and expertise can be developed as proposed here, a single UAS operator could treat more than 60 acres per hour.

If the equipment can be developed to deposit 3 SPV doses simultaneously every second, as they envision is possible, some 200 acres per hour could be treated by a single operator. The idea is that the drone would fire the treats in 3 different directions to increase the spread of treats.

The areas to be treated are located in South Phillips County, Montana.

Autonomous Delivery Robots Launched in Europe and USA

Starship Technologies is launching a fleet of autonomous delivery robots on the pavements of the United Kingdom, Germany and Switzerland as part of the testing program. A similar program will be announced for the United States shortly.

The largest European food delivery company Just Eat, leading German parcel delivery company Hermes, leading German retailer Metro Group, and innovative London food delivery startup Pronto will test the delivery robots developed by Starship Technologies, a company launched in 2014 by Skype co-founders.

As part of the program, dozens of robots will be deployed in five cities to run first test deliveries and introduce the innovative devices to the general public.

“By launching partnerships with major companies we will enter the next phase in our development. While Starship has been testing the robots in 12 countries in the last nine months, we will now develop know-how on running real robotic delivery services,” said Ahti Heinla, co-founder, CEO and CTO of Starship Technologies.

Robots developed by Starship Technologies are meant for delivering packages, groceries and food to consumers in a 2-3 mile radius. The robots can drive autonomously while being monitored by human operators in control centers. Introduced to European and American cities since the end of last year, the robots have already driven close to 5,000 miles and met over 400,000 people without a single accident.

Frank Rausch, CEO of Hermes Germany, said: “We are very proud to be Starship’s exclusive logistics partner in Germany. At Hermes we believe that parcel delivery’s main goal is to fully satisfy the customers’ needs in receiving their online shopping orders as fast and convenient as possible. Nobody likes to spend hours waiting for the courier just to have a parcel delivered. Therefore, individually scheduled delivery services will become increasingly important within the coming years.”

The test programs will run in London, Düsseldorf, Bern and another German city to start, before moving to several other European and American cities. Starship Technologies will also continue testing in Tallinn, Estonia where its R&D facilities are located.

Cleaning Up the Plastic Pollution in Our Oceans

This is an interesting talk on an important topic: cleaning up plastic in the ocean. ,a student from the Netherlands, looked to find a solution to a problem others said couldn’t be solved.

This is exactly the type of wonderful activity that inspired people can accomplish using science and engineering. He collected an understanding of the 50 issues that supposedly makes a solution impossible.

After getting funding (sparked by an explosion of viral social media) he worked on exploring the “insolvable” problems (having withdrawn from school to work on this problem). It is wonderful to see what we can do when inspired people use science and engineering to make the world a better place.

From their website, The Ocean Cleanup

In the feasibility report, we estimated that a 100-kilometer array operating in the North Pacific gyre for 10 years could remove 42% of the plastics in the area, or an estimated 70 million kilograms.

The plastic will be stored in an internal buffer within the platform at the tip of the V-shaped array. The plastic in the buffer will regularly be emptied onto a vessel that comes to collect it for transport to land. This will occur approximately once every six weeks, depending on the size of the vessel.

Besides monetary support, your relevant knowledge and skills may be a very welcome addition to The Ocean Cleanup. Our work requires not only scientific and technical expertise, but also assistance with legal, commercial and policy matters. If you would like to get actively involved in our work, If you would like to get actively involved in our work, please visit the careers page.

They aim to put a full scale pilot project in place in 3 to 4 years.
