Unexpected Andromedid meteor outburst, strongest ever detected by CMOR

Andromedid meteor outburst

This radar sky map shows a hot spot of meteor activity on Nov. 28th.
The Andromedids are back. Over the weekend astronomers reported an outburst of more than 100 faint meteors per hour. "[It was] the strongest outburst of Andromedid meteors ever detected by the Canadian Meteor Orbit Radar (CMOR)," says Peter Brown of the University of Western Ontario.

The shower's not over yet. "The current outburst is ongoing and it may be another few days or even a week before the activity ramps down," says Brown. "These meteors are too faint to see with the naked eye, but they are easy targets for our radar."

Andromedids are debris from Biela's Comet, known to historians as "the comet that split in two." 3D/Biela started to fall apart not long after it was discovered in 1772. It was a double comet when it swung by Earth in 1852 and, after that, was never seen again. In 1872 and 1885, thousands of meteors shot out of the constellation Andromeda as Earth passed through Biela's remains. Chinese records described "stars that fell like rain."

A large asteroid the size of the Washington Monument is heading for Earth in late December that, if it impacts, would cause devastation far greater than an atomic bomb, according to NASA's asteroid tracker.

Known as 2018 AH, this asteroid is estimated to be about 190 meters wide and is set to pass by the Earth on December 27.

The asteroid is unlikely to hit the planet, however, expected to pass by at a distance of more than 4.5 million kilometers. For comparison, the distance between the Earth and the Moon is around 384,000 km. - about a twelfth of that.

Comment: Whilst this asteroid is unlikely to be 'the one' to shake things up on our planet, it's notable that The Jerusalem Post, along with a variety of other mainstream news outlets - and not just the sensationalist tabloids - as well as research institutions around the world are increasingly sounding the alarm of the very real possibility of a space rock paying us a visit: And check out SOTT radio's:

COVID Trends • October 2021
"The PCR is a Process. It does not tell you that you are sick".
-Dr. Kary Mullis, Nobel Laureate and Inventor of the RT-PCR, passed away in August 2019
"...All or a substantial part of these positives could be due to what's called false positives tests."
-Dr. Michael Yeadon, Former Vice President and Chief Science Officer for Pfizer
This misuse of the RT-PCR technique is applied as a relentless and intentional strategy by some governments to justify excessive measures such as the violation of a large number of constitutional rights, ... under the pretext of a pandemic based on a number of positive RT-PCR tests, and not on a real number of patients.
-Dr. Pascal Sacré, Belgian physician specialized in critical care and renowned public health analyst
Introduction

Media lies coupled with a systemic and carefully engineered fear campaign have sustained the image of a killer virus which is relentlessly spreading to all major regions of the World.

Several billion people in more than 190 countries have been tested (as well as retested) for Covid-19. At the time of writing, approximately 260 million people Worldwide have been categorized as "confirmed Covid-19 cases". The alleged pandemic is said to have resulted in more than 5 million Covid-19 related deaths. Both sets of figures: morbidity and mortality are fabricated.

Six unmanned high-speed vessels cruise and guard Chinese sea territory in a highly dynamic, complex environment.
An unmanned high-speed vessel developed by Yunzhou Tech, a leading developer of unmanned surface vehicles, has achieved a breakthrough in its dynamic cooperative confrontation technology, which could quickly intercept, besiege and expel invasive targets, marking a milestone in maritime unmanned intelligence equipment development, the Global Times learned on Sunday.

Compared with manned vessels, ship drones have the advantages of low cost, multiple functions, strong scalability, high mobility and long duration. They can adapt to special and extreme environments, and they have huge advantages in maritime development and rights protection.

A video posted by the company shows six high-speed unmanned vessels cruising and guarding Chinese sea territory in a highly dynamic, complex environment. They conduct collaborative perception, high-speed tracking, evidence collection, interception and expelling unknown targets at sea. During the whole process, the ship drone swarms can make decisions completely on their own.

UC San Diego researchers introduce Multi-Scale Integrated Cell (MuSIC), a technique that combines microscopy, biochemistry and artificial intelligence, revealing previously unknown cell components that may provide new clues to human development and disease. (Artist’s conceptual rendering.).
Most human diseases can be traced to malfunctioning parts of a cell — a tumor is able to grow because a gene wasn't accurately translated into a particular protein or a metabolic disease arises because mitochondria aren't firing properly, for example. But to understand what parts of a cell can go wrong in a disease, scientists first need to have a complete list of parts.

By combining microscopy, biochemistry techniques and artificial intelligence, researchers at University of California San Diego School of Medicine and collaborators have taken what they think may turn out to be a significant leap forward in the understanding of human cells.

The technique, known as Multi-Scale Integrated Cell (MuSIC), is described November 24, 2021 in Nature.

In the quantum realm, not even time flows as you might expect

New study shows the boundary between time moving forward and backward may blur in quantum mechanics.
Time Flows

A team of physicists at the Universities of Bristol, Vienna, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum systems can simultaneously evolve along two opposite time arrows - both forward and backward in time.

The study, published in the latest issue of Communications Physics, necessitates a rethink of how the flow of time is understood and represented in contexts where quantum laws play a crucial role.

For centuries, philosophers and physicists have been pondering the existence of time. Yet, in the classical world, our experience seems to extinguish any doubt that time exists and goes on. Indeed, in nature, processes tend to evolve spontaneously from states with less disorder to states with more disorder and this propensity can be used to identify an arrow of time. In physics, this is described in terms of 'entropy', which is the physical quantity defining the amount of disorder in a system.

Dr Giulia Rubino from the University of Bristol's Quantum Engineering Technology Labs (QET labs) and lead-author of the publication, said: "If a phenomenon produces a large amount of entropy, observing its time-reversal is so improbable as to become essentially impossible. However, when the entropy produced is small enough, there is a non-negligible probability of seeing the time-reversal of a phenomenon occur naturally.

An analysis of published scientific research suggests possibly editorial bias "nepotistic behavior" among subsets of biomedical journals, researchers said Tuesday.
Researchers said in a study published Tuesday published by PLOS Biology that they found possible editorial bias and "nepotistic behavior" in a subset of biomedical journals.

The analysis, which included nearly 5 million articles published in nearly 5,500 publications between 2015 and 2019, found that most journals publish work by a large number of authors.

But a small number of journals featured "hyper-prolific" individuals that were published disproportionately more often -- and that their papers were more likely to be accepted for publication within three weeks of submission.

Flesh-eating vulture bees evolved a gut that loves meat

Raw chicken baits attract vulture bees in Costa Rica
They might not sting, but there is nothing sweet about flesh-eating vulture bees.

Many entomologists will tell you that bees are basically wasps that became vegetarian, but a little-known species of tropical stingless bee, Trigona hypogea, has evolved to have a particular taste for raw flesh. They even have a special meat-chewing tooth, winning them the charming name of "vulture bees".

Now, a paper published in mBio, also describes how the vulture bees have the omnivorous microbiome to match, including familiar bacteria in sourdough, and even take home meaty leftovers.

"These are the only bees in the world that have evolved to use food sources not produced by plants, which is a pretty remarkable change in dietary habits," says entomologist Doug Yanega from the University of California (UC), US, who was involved in the study.

The most recent gravitational wave observing run has netted the biggest haul yet.

In less than five months, from November 2019 to March 2020, the LIGO-Virgo interferometers recorded a massive 35 gravitational wave events. On average, that's almost 1.7 gravitational wave events every week for the duration of the run.

This represents a significant increase from the 1.5-event weekly average detected on the previous run, and a result that has plumped up the number of total events to 90 since that first history-making gravitational wave detection in September 2015.

"These discoveries represent a tenfold increase in the number of gravitational waves detected by LIGO and Virgo since they started observing," said astrophysicist Susan Scott of the Australian National University in Australia.

Latest discoveries in the field of structural biology point to Intelligent Design

The August 9, 2021 edition of Chemical and Engineering News (C&EN) featured a story in the field of structural biology entitled "How Transcription Gets Its Start." Transcription is the biochemical process that occurs in every cell in the human body when protein synthesis is initiated. It is a complex series of steps that begin in the nucleus when a gene — a section on a strand of DNA — expresses instructions for a specific protein to be produced.

In simple terms, the portion of the DNA molecule where the gene is located is unzipped resulting in a strand of mRNA (messenger RNA). mRNA can be thought of as a digital tape that contains a sequence of 3-letter codes called codons that dictate the precise sequence of amino acids for the protein it is about to produce.

The mRNA leaves the nucleus and enters the site of protein synthesis called a ribosome. It is here that the codons are read and the specific amino acids are delivered by a second RNA molecule, tRNA (transfer RNA) which has its own 3-letter sequences called anti-codons that match the codons on the mRNA. The process continues; the ribosome continues assembling the amino acids one-by-one until the protein has been assembled according to the instructions originally encoded on the gene.
