Cellular Computing: “Logic Gate” Paves Way for Nanoscale Computers To Treat Cancer and Other Diseases

The creation of nanoscale computers for use in precision health care has long been a dream of many scientists and health care providers. Now, for the first time, researchers at Penn State have produced a nanocomputing agent that can control the function of a particular protein that is involved in cell movement and cancer metastasis. The research paves the way for the construction of complex nanoscale computers for the prevention and treatment of cancer and other diseases.

Nikolay Dokholyan, G. Thomas Passananti Professor, Penn State College of Medicine, and his colleagues — including Yashavantha Vishweshwaraiah, postdoctoral scholar in pharmacology, Penn State — created a transistor-like ‘logic gate,’ which is a type of computational operation in which multiple inputs control an output.

“Our logic gate is just the beginning of what you could call cellular computing,” he said, “but it is a major milestone because it demonstrates the ability to embed conditional operations in a protein and control its function, said Dokholyan. ” It will allow us to gain a deeper understanding of human biology and disease and introduces possibilities for the development of precision therapeutics.”

Scientists Warn of “Alien” Invasions and the Need for Planetary Biosecurity

The era of space exploration brings with it a new risk: invasion. The peril comes not from little green men arriving on flying saucers but, rather, from microbiological contamination of Earth from extraterrestrial environments and vice versa. Writing in BioScience, Anthony Ricciardi, of McGill University, and colleagues describe the dangers posed by such organisms and outline an approach to address the threat.

The authors caution that biological contamination endangers both ecosystems and human well-being. “Owing to their massive costs to resource sectors and human health, biological invasions are a global biosecurity issue requiring rigorous transboundary solutions,” say Ricciardi and colleagues. And that threat may be more immediate than previously anticipated. Despite considerable microbial caution among space agencies, say the authors, “bacterial strains exhibiting extreme resistance to ionizing radiation, desiccation, and disinfectants have been isolated in NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is To discover and expand knowledge for the benefit of humanity.

Mr. Temitayo Erogbogbo, Global Advocacy Director, MSD for Mothers (Merck Sharp & Dohme)

Creating a world where no woman has to die giving life — temitayo erogbogbo, global advocacy director, MSD for mothers, merck sharp & dohme.


Mr. Temitayo (Tayo) Erogbogbo, is Global Advocacy Director of MSD for Mothers (https://www.msdformothers.com/), at Merck Sharp & Dohme.

Tayo has two decades of combined private sector and international development experience, 13 years of which was spent in the pharmaceutical industry in multiple roles across community relations, government affairs, marketing and sales.

As the Global Advocacy Director of MSD for Mothers, Tayo is responsible for global and national strategic partnerships and programs to bring about policies and practice changes to improve maternal health care, and strengthen health systems, particularly where private sector approaches can be leveraged for greater impact.

Prior to MSD for Mothers, Tayo led the establishment of an adolescents and youth constituency at The Partnership for Maternal, Newborn and Child Health (PMNCH), a multi-constituency partnership hosted by the World Health Organization, to advocate for better sexual, reproductive, maternal, newborn, child, and adolescent health policies and services at global, regional, and national levels. Additionally, he contributed to the development of the Global Strategy for Women’s, Children’s, and Adolescents’ Health 2016–2030.

Tardigrades: Why water bears could be the first interstellar astronauts

It’s more likely than you think.


When it comes to interstellar missions, however, there are no plans for crewed missions on the table. While there are proposals for sending robotic missions, sending astronauts to nearby stars and exoplanets simply isn’t feasible yet.

However, according to new research led by the University of California, interstellar missions could be conducted in the near future that would have tardigrades (aka. “Water Bears”) as their crew.

The study, titled “The First Interstellar Astronauts Will Not Be Human,” was conducted by researchers from UC Santa Barbara, the UCLA Health Center, the University of Florida, and Ruhr-University Bochum. It will be published in the January 2022 issue of Acta Astronautica.

Pfizer pledges shipment of new antiviral COVID pill to Israel — report

Pfizer has pledged a shipment of its experimental antiviral COVID-19 pill to Israel, according to a Saturday television report, a week after the US drugmaker said it was engaged in “active discussion” with 90 countries regarding the coronavirus medication.

Prime Minister Naftali Bennett and Health Minister Nitzan Horowitz reached an agreement with the drug company for tens of thousands of doses, Channel 12 news reported. The shipment will be despatched as soon as Pfizer receives FDA approval for the pill, the TV report said.


PM and health minister reach agreement with drug company for ‘tens of thousands of doses’; initial data shows almost 90% efficacy.

“Whispering Gallery” Microresonator Can Measure Individual Nanoparticles

Forget all the nanotechnology devoted to fighting cancer, and just consider that nanoparticles have invaded makeup, anti-odor socks, sunscreen, plastic beer bottles and home pregnancy tests. Now scientists have developed a way to assess the health and environmental impact of such nanoparticles: a tiny microresonator that can detect and measure individual particles smaller than a single virus.

The microresonator is a lab-on-a-chip that harnesses the “whispering gallery” concept that’s displayed by buildings such as St. Paul’s Cathedral in London. The cathedral’s domed gallery can carry whispers easily across to the other side, but normal-volume voices end up garbled after bouncing around the dome multiple times.

Similarly, microresonators can bounce laser light many times around a circular “waveguide,” such as a glass ring. A laser frequency must perfectly fit the circumference of a ring to achieve this whispering-gallery mode.

Apple’s Increasing Focus on Health Seen in Recent Hiring Trends, New Board Member

Apple has been talking for years about the role it wants to play in human health, led by the Apple Watch and its array of health-related features. With the Apple Watch maturing and Apple increasing its integration of health-focused hardware and software, several pieces of evidence suggest the company is positioning itself for an even bigger expansion in that direction.

According to trends compiled by Linkedin and seen by MacRumors, over the past year, Apple’s open job listings in health-related fields have increased by over 220%, with a significant portion of the increase coming in just the last several months. Apple’s health-focused hiring has been the fastest-growing segment for the company over the past year, followed most closely by sales and IT specialists, such as in cloud computing and security, according to the data.

Self-Driving Farm Robot Uses Lasers To Kill 100,000 Weeds An Hour, Saving Land And Farmers From Toxic Herbicides

The nutrient content of our vegetables is down 40% over the last two decades and our soil health is suffering due to increasingly harsh herbicide use, according to Carbon Robotics founder Paul Mikesell. And farmers are increasingly concerned about the long-term health impacts of continually spraying chemicals on their fields.

But not weeding will cost half your crop, killing profitability.

The solution?
