The spike protein of SARS-CoV-2 variant A.30 is heavily mutated and evades vaccine-induced antibodies with high efficiency

Posted by in categories: biotech/medical, economics, health

The COVID-19 pandemic, caused by SARS-CoV-2, continues to rage in many countries, straining health systems and economies. Vaccines protect against severe disease and death and are considered central to ending the pandemic. COVID-19 vaccines (and SARS-CoV-2 infection) elicit antibodies that are directed against the viral spike (S) protein and neutralize the virus. However, the emergence of SARS-CoV-2 variants with S protein mutations that confer resistance to neutralization might compromise vaccine efficacy[1]. Furthermore, emerging viral variants with enhanced transmissibility, likely due to altered virus-host cell interactions, might rapidly spread globally. Therefore, it is important to investigate whether emerging SARS-CoV-2 variants exhibit altered host cell interactions and resistance against antibody-mediated neutralization.

FlexSail: Solar Sails and Tech Revolutions — Kent Nebergall — 2021 Mars Society Virtual Convention

Posted by in categories: bioengineering, economics, environmental, genetics, government, information science, robotics/AI, solar power, space, sustainability

Track code: TD-3

Abstract:
Solar Sails are at the same stage of engineering development as electric motors were in the 1830’s. Each attribute of solar flux has been examined in isolation, such as photon, proton, plasma, and electrodynamic systems. This talk recommends designing a simple baseline system that converges multiple propulsion methods into optimized systems, as is currently done with electric motors. Many convergences can come from this solution space. Once a baseline design is created, AI genetic algorithms can “flight test” and refine the designs in simulation to adjust proportions and geometry. Once a base design is refined, a second AI evolution pass would design fleet systems that flock like birds to optimize performance. These could fly as a protective shield around Mars crewed fleets, provide space based solar power, deploy rapid reaction probes for interstellar comets, and be used in NEO asteroid mining. In the long term, fleets of solar energy management vehicles can provide orbital Carrigan event protection and Martian solar wind protection for terraforming. This talk is also a case study in how technology revolutions happen, and how to accelerate the creation and democratization of technical solutions.

Lab-grown meat: The future of food? | FT Food Revolution

Posted by in categories: economics, futurism

Rearing animals for human consumption and clearing land to grow their feed causes untold environmental damage. Mass-producing plant-based proteins could be equally unsustainable. New technologies are being developed to grow pork, beef and chicken-like tissue in the lab, but can output be upscaled enough to make a real difference?

Net Zero Strategy 2021. Through Disruptive Technology & The Power Of Exponential Growth & Uptake

Posted by in categories: biotech/medical, business, economics, food, media & arts, mobile phones, robotics/AI

We are living in a time when we can see what needs to be done, but the industrial legacy of the last century has such power invested, politically and in the media, and so much money at its disposal due to the investors who have too much to lose to walk away, and so they throw good money after bad to desperately try to save their stranded assets.

Well, the next decade will bring new technologies which will rupture the business models of the old guard, tipping the balance on their huge economies of scale, which will quickly disintegrate their advantage before consigning them to history, and these new ways of doing things will be better for us and the environment, and cheaper than every before. Just look at how the internet and the smart phone destroyed everything from cameras to video shops to taxis and the very high street itself.

Covert Cognizance: A Novel Predictive Modeling Paradigm

Posted by in categories: cybercrime/malcode, economics, information science, nuclear energy, robotics/AI

(2021). Nuclear Technology: Vol. 207 No. 8 pp. 1163–1181.


Focusing on nuclear engineering applications, the nation’s leading cybersecurity programs are focused on developing digital solutions to support reactor control for both on-site and remote operation. Many of the advanced reactor technologies currently under development by the nuclear industry, such as small modular reactors, microreactors, etc., require secure architectures for instrumentation, control, modeling, and simulation in order to meet their goals. 1 Thus, there is a strong need to develop communication solutions to enable secure function of advanced control strategies and to allow for an expanded use of data for operational decision making. This is important not only to avoid malicious attack scenarios focused on inflicting physical damage but also covert attacks designed to introduce minor process manipulation for economic gain. 2

These high-level goals necessitate many important functionalities, e.g., developing measures of trustworthiness of the code and simulation results against unauthorized access; developing measures of scientific confidence in the simulation results by carefully propagating and identifying dominant sources of uncertainties and by early detection of software crashes; and developing strategies to minimize the computational resources in terms of memory usage, storage requirements, and CPU time. By introducing these functionalities, the computers are subservient to the programmers. The existing predictive modeling philosophy has generally been reliant on the ability of the programmer to detect intrusion via specific instructions to tell the computer how to detect intrusion, keep log files to track code changes, limit access via perimeter defenses to ensure no unauthorized access, etc.

Real-Time Bidding: The Ad Industry Has Crossed A Very Dangerous Line

Posted by in categories: business, economics, ethics, policy

This post is a collaboration with Dr. Augustine Fou, a seasoned digital marketer, who helps marketers audit their campaigns for ad fraud and provides alternative performance optimization solutions; and Jodi Masters-Gonzales, Research Director at Beacon Trust Network and a doctoral student in Pepperdine University’s Global Leadership and Change program, where her research intersects at data privacy & ethics, public policy, and the digital economy.

The ad industry has gone through a massive transformation since the advent of digital. This is a multi-billion dollar industry that started out as a way for businesses to bring more market visibility to products and services more effectively, while evolving features that would allow advertisers to garner valuable insights about their customers and prospects. Fast-forward 20 years later and the promise of better ad performance and delivery of the right customers, has also created and enabled a rampant environment of massive data sharing, more invasive personal targeting and higher incidences of consumer manipulation than ever before. It has evolved over time, underneath the noses of business and industry, with benefits realized by a relative few. How did we get here? More importantly, can we curb the path of a burgeoning industry to truly protect people’s data rights?

There was a time when advertising inventory was finite. Long before digital, buying impressions was primarily done through offline publications, television and radio. Premium slots commanded higher CPM (cost per thousand) rates to obtain the most coveted consumer attention. The big advertisers with the deepest pockets largely benefitted from this space by commanding the largest reach.

======
Raptor and BE4SpaceX and Blue Origin have been competing with each other for many space crafts and commercial contracts. We have also talked about their rivalry many times but today is all about their engines that fire up the massive rockets both the companies are developing. SpaceX, the leading space company has made many rocket engines since its launch in 2002. A few months ago, SpaceX completed its 100th Raptor Engine. This extraordinary milestone was achieved in just 29 months. Blue Origin’s rocket engines game started work on the BE-4 in 2011. Importantly, they said the “BE-4 would be ‘ready for flight’ by 2017″, but at this moment Blue Origin’s powerful BE-4 engine is more than four years late. The first flight test of the new engine is now expected no earlier than 2022 on the Vulcan rocket. This is a big problem and we need to talk about that.
So, How did Blue Origin’s BE-4 turn into a joke whereas SpaceX’s Raptor is the leading example?
Let’s find out:
Firstly, how has BE-4 gone through almost a decade of failure?
This was their first engine to combust liquid oxygen and liquified natural gas propellants. It was initially planned for the engine to be used exclusively on a Blue Origin proprietary launch vehicle New Glenn, the company’s first orbital rocket. However, it was announced in 2014 that the engine would also be used on the United Launch Alliance (ULA) Vulcan Centaur launch vehicle, the successor to the Atlas V launch vehicle. This was labeled “a stunner” choice. The company planned to begin full-scale engine testing in late 2016 and expected to complete the development of the engine in 2017.However, the first engine was not fully assembled until March 2017. Also, in March, United Launch Alliance indicated that the economic risk of the Blue Origin engine selection option had been retired, but that the technical risk on the project would remain until a series of engine firing tests were completed later in 2017. A test anomaly occurred on 13 May 2017 and Blue Origin reported that they lost a set of powerpack hardware.
