There is quanta of space time just as there is for particles and fields created by entanglement or liebnitz was right and spacetime are relational entities.
Scientists believe that spacetime may have emerged, in part, from a quantum property called “magic.”

It is true that the next pandemic is a matter of “when,” not “if.” The statistical certainty of a future pandemic has led to increasing research into potential pandemic pathogens so that we may create lifesaving countermeasures. Such research, unfortunately, also carries a risk of bringing about exactly what it seeks to prevent. Human error or even deliberate action is as likely to be the cause of the next pandemic as natural origin. Such concerns have intensified after the COVID-19 pandemic, which a significant percentage of the US population, at least, believes began with a research accident, one of the two main pandemic origin theories, with the other being the jump of a virus from animals to people. The question then for governments and the research community is how to build confidence in the valuable work that scientists do through appropriate regulation.
While research with favorable risk-benefit profiles must be facilitated, high-risk research of either limited benefits or benefits for only a limited few must be seen through a different regulatory lens.
To use the Instagram Chandra experience, search for the “NASAChandraXray” account. Select the effects options (the tab that looks like three four-pointed stars) and select the one you want. Then, you can either save the effect to your camera and apply it to your stories, or you can select the “Try it” button for instant access.

“We are excited to bring data from the universe down to Earth in this way,” Kimberly Arcand, Chandra X-ray Center visualization and emerging technology scientist, said in a statement. “Enabling people to access cosmic data on their phones and through AR brings Chandra’s amazing discoveries literally right to your fingertips.”
Google has accidentally collected childrens’ voice data, leaked the trips and home addresses of car pool users, and made YouTube recommendations based on users’ deleted watch history, among thousands of other employee-reported privacy incidents, according to a copy of an internal Google database which tracks six years worth of potential privacy and security issues obtained by 404 Media.
Individually the incidents, most of which have not been previously publicly reported, may only each impact a relatively small number of people, or were fixed quickly. Taken as a whole, though, the internal database shows how one of the most powerful and important companies in the world manages, and often mismanages, a staggering amount of personal, sensitive data on people’s lives.
The data obtained by 404 Media includes privacy and security issues that Google’s own employees reported internally. These include issues with Google’s own products or data collection practices; vulnerabilities in third party vendors that Google uses; or mistakes made by Google staff, contractors, or other people that have impacted Google systems or data. The incidents include everything from a single errant email containing some PII, through to substantial leaks of data, right up to impending raids on Google offices. When reporting an incident, employees give the incident a priority rating, P0 being the highest, P1 being a step below that. The database contains thousands of reports over the course of six years, from 2013 to 2018.
Russian organizations are at the receiving end of cyber attacks that have been found to deliver a Windows version of a malware called Decoy Dog.
Cybersecurity company Positive Technologies is tracking the activity cluster under the name Operation Lahat, attributing it to an advanced persistent threat (APT) group called HellHounds.
“The Hellhounds group compromises organizations they select and gain a foothold on their networks, remaining undetected for years,” security researchers Aleksandr Grigorian and Stanislav Pyzhov said. “In doing so, the group leverages primary compromise vectors, from vulnerable web services to trusted relationships.”
A massive trove of 361 million email addresses from credentials stolen by password-stealing malware, in credential stuffing attacks, and from data breaches was added to the Have I Been Pwned data breach notification service, allowing anyone to check if their accounts have been compromised.
Cybersecurity researchers collected these credentials from numerous Telegram cybercrime channels, where the stolen data is commonly leaked to the channel’s users to build reputation and subscribers.
The stolen data is usually leaked as username and password combinations (usually stolen via credential stuffing attacks or data breaches), username and passwords along with a URL associated with them (stolen via password-stealing malware), and raw cookies (stolen via password-stealing malware).
Statistical properties of fluctuations of certain parameters describing a complex system can reveal when that system is approaching a tipping point.
Using an atomic array originally designed for quantum memory, researchers have demonstrated a magnetometer with unprecedented spatial resolution.
A new model, vetted by experiments on lung cancer cells, may help to explain how cancer and other diseases accumulate drug-resistance mutations that can compromise the effectiveness of treatments.
During the past 50 years, researchers have accumulated a massive arsenal in our war on cancer. Well over 500 drugs have been approved to treat tumors, but cancer remains the second leading cause of death in the United States. The problem is partly due to drug resistance—the emergence of treatment-resistant mutants of the original disease. Now a study led by Jeff Maltas of Cleveland Clinic and Case Western Reserve University, both in Ohio, puts forward a model explaining why drug resistance is so common, vetting the model with experiments on lung cancer cells [1]. This model indicates that treatment-resistant mutants can be present in larger-than-expected numbers before treatment begins. The conclusion implies that we cannot understand cancer evolution by looking at individual mutations in isolation; instead, we should consider each tumor as an interacting ecosystem.
Mentally stimulating activities and life experiences can improve cognition in memory clinic patients, but stress undermines this beneficial relationship. This is according to a new study from Karolinska Institutet published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
In the late 1980s, researchers discovered that some individuals who showed no apparent symptoms of dementia during their lifetime had brain changes consistent with an advanced stage of Alzheimer’s disease. Since then it has been postulated that so-called cognitive reserve might account for this differential protective effect in individuals.
Cognitively stimulating and enriching life experiences and behaviors such as higher educational attainment, complex jobs, continued physical and leisure activities, and healthy social interactions help build cognitive reserve. However, high or persistent stress levels are associated with reduced social interactions, impaired ability to engage in leisure and physical activities, and an increased risk of dementia.
