It didn’t take long. Intelligence agencies and cybersecurity researchers had been warning that unpatched Exchange Servers could open the pathway for ransomware infections in the wake of swift escalation of the attacks since last week.

Now it appears that threat actors have caught up.

According to the latest reports, cybercriminals are leveraging the heavily exploited ProxyLogon Exchange Server flaws to install a new strain of ransomware called “DearCry.”

Most new achievements in artificial intelligence (AI) require very large neural networks. They consist of hundreds of millions of neurons arranged in several hundred layers, i.e. they have very ‘deep’ network structures. These large, deep neural networks consume a lot of energy in the computer. Those neural networks that are used in image classification (e.g. face and object recognition) are particularly energy-intensive, since they have to send very many numerical values from one neuron layer to the next with great accuracy in each time cycle.

Computer scientist Wolfgang Maass, together with his Ph.D. student Christoph Stöckl, has now found a design method for artificial neural networks that paves the way for energy-efficient high-performance AI hardware (e.g. chips for driver assistance systems, smartphones and other mobile devices). The two researchers from the Institute of Theoretical Computer Science at Graz University of Technology (TU Graz) have optimized artificial neuronal networks in computer simulations for image classification in such a way that the neurons —similar to neurons in the brain—only need to send out signals relatively rarely and those that they do are very simple. The proven classification accuracy of images with this design is nevertheless very close to the current state of the art of current image classification tools.

What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter? Dark matter comprises the majority of matter in the Universe, but its nature remains unknown.

Multiple gravitational wave detections of merging black holes have been identified within the last few years by the Laser Interferometer Gravitational-Wave Observatory (LIGO), commemorated with the 2017 physics Nobel Prize to Kip Thorne, Barry Barish, and Rainer Weiss. A definitive confirmation of the existence of black holes was celebrated with the 2020 physics Nobel Prize awarded to Andrea Ghez, Reinhard Genzel and Roger Penrose. Understanding the origin of black holes has thus emerged as a central issue in physics.

Surprisingly, LIGO has recently observed a 2.6 solar-mass black hole candidate (event GW190814, reported in Astrophysical Journal Letters 896 (2020) 2, L44). Assuming this is a black hole, and not an unusually massive neutron star, where does it come from?

I didn’t get my 2nd Moderna Vaccine because how sick others became after theirs — nausea, fatigue, headaches for days, lymph nodes the size of a rock that fits in your hand, increased heart rate… Recently a Utah woman died 4 days after her 2nd vaccine-her heart, liver and kidneys failed. Less then a yr ago I read several studies on hospitalized COVID patients — how their kidneys and liver were failing. I read a recent study on how post COVID individuals are now having heart issues. Another study shows how COVID attacks the heart and why such individuals are now having heart issues. In December 2020, 13 individuals died after getting vaccinated (probably more since then). There is a real connection between COVID and organ failure!!!! I wish I kept links of all the information I read. Be happy to find them again. We don’t even know the long term affects of the vaccine — are the vaccinated going to experience long term health issues as well? Take your chances with a vaccine, or not.

A Utah woman in her 30s died four days after receiving the coronavirus vaccine.

Kassidi Kurill, 39, was healthy and happy and “had more energy” than others, according to a KUTV report. Then, four days after she received her second dose of the coronavirus vaccine, she suddenly died.

Many post COVID victims have heart issues. This is why:

A new study has discovered how the SARS-CoV-2 virus attacks and damages the heart, answering a long-standing question about mysterious heart conditions following COVID-19 infection. The results could have large implications on how to effectively treat severe infections and develop new therapies for preventing long-term damage.

Throughout the pandemic, people with severe COVID-19 infection have often displayed symptoms of heart distress. Those with underlying heart conditions are at a greater risk of severe illness if they catch it, and reports of abnormal heart rhythms (arrhythmia) in previously healthy patients with acute COVID-19 have been common.

University of Chicago researchers hunt for proposed particles that could explain quirks of the universe.

A team of researchers at the University of Chicago recently embarked on the search of a lifetime—or rather, a search for the lifetime of long-lived supersymmetric particles.

Supersymmetry is a proposed theory to expand the Standard Model of particle physics. Akin to the periodic table of elements, the Standard Model is the best description we have for subatomic particles in nature and the forces acting on them.

The recent synthesis of one-dimensional van der Waals heterostructures, a type of heterostructure made by layering two-dimensional materials that are one atom thick, may lead to new, miniaturized electronics that are currently not possible, according to a team of Penn State and University of Tokyo researchers.

Engineers commonly produce heterostructures to achieve new device properties that are not available in a single material. A van der Waals heterostructure is one made of 2D materials that are stacked directly on top of each other like Lego-blocks or a sandwich. The van der Waals force, which is an attractive force between uncharged molecules or atoms, holds the materials together.

According to Slava V. Rotkin, Penn State Frontier Professor of Engineering Science and Mechanics, the one-dimensional van der Waals heterostructure produced by the researchers is different from the van der Waals heterostructures engineers have produced thus far.
