Vermont Hospital confirmed the ransomware attack

Posted by in categories: biotech/medical, cybercrime/malcode, health

In October, threat actors hit the Wyckoff Heights Medical Center in Brooklyn and the University of Vermont Health Network. The cyber attack took place on October 28 and disrupted services at the UVM Medical Center and affiliated facilities.

A month later, the University of Vermont Medical Center was continuing to recover from the cyber attack that paralyzed the systems at the Burlington hospital.

In early December, Hospital CEO Dr. Stephen Leffler announced that the attack that took place in late October on the computer systems of the University of Vermont Medical Center is costing the hospital about $1.5 million a day in lost revenue and recovery costs.

Scientists turn CO2 into jet fuel

Posted by in categories: sustainability, transportation

Researchers may have found a way to reduce the environmental impact of air travel in situations when electric aircraft and alternative fuels aren’t practical. Wired reports that Oxford University scientists have successfully turned CO2 into jet fuel, raising the possibility of conventionally-powered aircraft with net zero emissions.

The technique effectively reverses the process of burning fuel by relying on the organic combustion method. The team heated a mix of citric acid, hydrogen and an iron-manganese-potassium catalyst to turn CO2 into a liquid fuel capable of powering jet aircraft.

Is Dark Energy Really “Repulsive Gravity”?

Posted by in category: cosmology

Circa 2012 o.o


“Repulsive gravity”—a powerful repulsion between matter and antimatter—could explain the force known as dark energy, a new theory claims.

Repulsive gravity as an alternative to dark energy (Part 2: In the quantum vacuum)

Posted by in categories: cosmology, particle physics, quantum physics

Circa 2012


(PhysOrg.com) — During the past few years, CERN physicist Dragan Hajdukovic has been investigating what he thinks may be a widely overlooked part of the cosmos: the quantum vacuum. He suggests that the quantum vacuum has a gravitational charge stemming from the gravitational repulsion of virtual particles and antiparticles. Previously, he has theoretically shown that this repulsive gravity can explain several observations, including effects usually attributed to dark matter. Additionally, this additional gravity suggests that we live in a cyclic Universe (with no Big Bang) and may provide insight into the nature of black holes and an estimate of the neutrino mass. In his most recent paper, published in Astrophysics and Space Science, he shows that the quantum vacuum could explain one more observation: the Universe’s accelerating expansion, without the need for dark energy.

“The was predicted theoretically more than 60 years ago,” Hajdukovic told PhysOrg.com. “Today, there is significant experimental evidence that the quantum vacuum exists. I have decided to combine one reality (the quantum vacuum) with one hypothesis (the negative gravitational charge of antiparticles) and to study the consequences. The hypothesis of the gravitational repulsion between matter and antimatter is older than half a century, but before me no one has used it in the combination with the quantum vacuum. … The results are surprising; there is potential to explain [the Universe’s accelerating expansion] in the framework of the quantum vacuum enriched with the gravitational repulsion between matter and antimatter.”

According to Hajdukovic, in the quantum vacuum arises from the gravitational between the positive gravitational charge of matter and the (hypothetical) negative gravitational charge of antimatter. While matter and antimatter are gravitationally self-attractive, they are mutually repulsive. (This part is similar to Massimo Villata’s theory from part 1, in which negatively charged antimatter exists in voids rather than in the quantum vacuum.) Although the quantum vacuum does not contain real matter and antimatter, short-lived and virtual antiparticles could momentarily appear and form pairs, becoming gravitational dipoles.

The unexpected benefits of virtual education

Posted by in categories: biotech/medical, education

It looks like virtual education(which is happening more now) is actually preparing students for the workplace of the future.


That said, there may be a silver lining to virtual classrooms and distance learning, which many universities and schools this academic year are defaulting to, in various degrees, due to the coronavirus. As students and teachers may have to compensate for logistic challenges, collaborating online might prepare high school students with the kind of organizational acumen, emotional intelligence and self-discipline needed for modern careers, particularly those that allow for the growing trend of working in remote, distributed teams. The sooner that students master those proficiencies, the better off they’ll be when they reach the job market.

The Timescape of Homo Sapiens: Insights on Our Time as a Species

Posted by in categories: futurism, genetics

You are an apogee of Earthly Nature encompassing numerous generations of humans as well as preceded non-human terrestrial life, sitting atop the tree of life… and so is everyone else who lives today. We all can be regarded as archetypes for future generations as well, or perhaps a “developing pattern,” if you intend to live indefinitely long. At any rate, genetically and anthropologically speaking, we all are one humongous extended family. #Timescape #HomoSapiens #ExponentialPedigree


This demographic research provides a host of quantifiable properties of the human species as a whole for further visualizing the data via certain graphs and diagrams. 5 trillion subjective years would constitute the ‘Timescape’ of Homo sapiens up to the p.
