WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING
THIS IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS
“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”
"Being a scientist is a state of mind, not a profession!"
"Science, when it's done right, can yield amazing things".
The Reach of Scientific Research From Labs to Laymen
The aim of science is not only to open a door to infinite knowledge and wisdom but to set a limit to infinite error.
"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.
Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.
If you are scientifically literate the world looks very different to you.
We do science and science communication not because they are easy but because they are difficult!
“Science is not a subject you studied in school. It’s life. We 're brought into existence by it!"

Researchers diffract a beam of organic molecules
A team of researchers has succeeded in diffracting a beam of organic molecules. In their paper published in the journal Physical Review Letters, the researchers describe demonstrating Bragg diffraction of the molecules ciprofloxacin and phthalocyanine.
Over the long history of wave-particle research, scientists have found that light is both a wave and a particle. They have also shown that electrons have a similar wave-particle duality. Physicists theorize that wave-particle duality is a fundamental feature of the universe. This suggests that all matter should have wave-like phenomena, which means that it should be able to behave in ways that are similar to light and electrons. As one example, it should be possible to demonstrate interference and diffraction of matter, such as whole molecules. In this new effort, the researchers have done exactly that by demonstrating a type of diffraction pattern with molecules of ciprofloxacin (an antibiotic) and phthalocyanine (a kind of dye).
The work involved firing a laser beam at a sheet of glass upon which the ciprofloxacin and phthalocyanine molecules were applied, forcing them to fly off the glass at a very rapid speed. The molecules flew toward a barrier with a vertical slit that allowed only those molecules traveling in the desired direction to pass through. Those that passed through were met by another laser beam focused with a standing wave pattern. The high-intensity parts of the beam deflected the molecules in a way akin to passing through a gap, which led to the creation of a diffraction pattern. The molecules were then directed through another slit and immediately thereafter impacted a flat screen, where they adhered. And because the types of molecules the researchers chose for the experiment glow when exposed to UV or blue light, the researchers were able to see them. By running the experiment for a short period of time, the researchers were able to observe a pattern appear on the screen—evidence of a diffraction pattern.
The researchers were able to create different patterns by using different initial laser velocities and different incident angles. They note also that the patterns were weak, though still observable, and agreed with theory.

Genomic basis of bat superpowers revealed: Like how they survive deadly viruses
The genetic material that codes for bat adaptations and superpowers—such as the ability to fly, to use sound to move effortlessly in complete darkness, to tolerate and survive potentially deadly viruses, and to resist aging and cancer—has been revealed and published.
One aspect of the paper findings shows evolution through gene expansion and loss in a family of genes, APOBEC3, which is known to play an important role in immunity to viruses in other mammals. The details in the paper that explain this evolution set the groundwork for investigating how these genetic changes, found in bats but not in other mammals, could help prevent the worst outcomes of viral diseases in other mammals, including humans.
The team compared these bat genomes against 42 other mammals to address the unresolved question of where bats are located within the mammalian tree of life. Using novel phylogenetic methods and comprehensive molecular data sets, the team found the strongest support for bats being most closely related to a group called Fereuungulata that consists of carnivorans (which includes dogs, cats and seals, among other species), pangolins, whales and ungulates (hooved mammals).
To uncover genomic changes that contribute to the unique adaptations found in bats, the team systematically searched for gene differences between bats and other mammals, identifying regions of the genome that have evolved differently in bats and the loss and gain of genes that may drive bats' unique traits
The researchers found evidence the exquisite genomes revealed "fossilized viruses," evidence of surviving past viral infections, and showed that bat genomes contained a higher diversity of these viral remnants than other species providing a genomic record of ancient historical interaction with viral infections. The genomes also revealed the signatures of many other genetic elements besides ancient viral insertions, including 'jumping genes' or transposable elements.

New model proposed to reduce carbon footprint
New model proposed to reduce carbon footprint: to bring the carbon footprint of international conferences down. The model can apply to small regional conferences as well. The model identifies three key areas for action; carefully selecting venues to minimize transport emissions, hosting conferences every second year to instantly cut travel by 50%, and creating hubs so people travel shorter distances to still benefit from networking while linking virtually to other hubs.

Using drones to reduce disease-spreading mosquito populations
Vector-borne diseases are illnesses that can be transmitted to humans by blood-feeding insects, such as mosquitoes, ticks and fleas. Mosquitoes are known to contribute to the spread of a number of vector-borne diseases, including malaria, dengue, yellow fever and Zika.
According to the World Health Organization (WHO), this class of diseases accounts for 17% of all infectious diseases in the world, causing over 1 million human deaths per year. Developing methods to reduce the spread and prevalence of these diseases is thus of utmost importance, as it could ultimately save countless human lives.
In recent years, scientists have devised a number of control methods to reduce or manage harmful insect populations without injecting harmful chemicals into the environment. One of these methods is the sterile insect technique (SIT), a form of insect birth control that entails the use of radiation to sterilize male mosquitoes, which are then released into the air in a target area and start mating with wild female insects.
As a sterile male and a fertile female do not produce any offspring after they mate, SIT produces a decline in the insect population. In order to reduce the incidence of vector-borne diseases, however, large amounts of good quality sterile insects need to be released continuously over affected geographical areas. Techniques for the cost-effective aerial release of sterile mosquitoes over extended geographical regions are thus a bottleneck to enabling the application of SIT on a large scale.
Researchers have recently developed a system to apply the SIT using unmanned aerial vehicles (UAVs), or drones, to manage and reduce vector-borne-disease-transmitting mosquito populations. This unique system entails the release of sterile mosquitoes in the air over large geographical areas using UAVs or drones. The system, tested in Brazil, enabled a uniform dispersal of sterile male Aedes aegypti mosquitoes while maintaining their quality, leading to a consistent sterile-to-wild male ratio.
The key goal of the study was to measure the survival, dispersal and sexual competitiveness of sterile male mosquitoes after they were mass-produced, sorted, handled, irradiated, marked and released within a geographical area using UAVs. The UAV-based release system they devised uses a canister in which mosquitoes are chilled down to 8-12 °C and compacted. Each canister can contain up to 50,000 sterile males. When the canister opens, the mosquitoes fall into a rotating cylinder that releases them into the open air with each of its rotations. The rotation speed controls the number of sterile males released per minute. It is fully automated, and release rates can be controlled depending on the location and speed of the drone.

Study reveals strange magnetic behaviour 8-11 million years ago
Research has revealed that strange behaviour of the magnetic field in the South Atlantic region existed as far back as eight to 11 million years ago, suggesting that today's South Atlantic Anomaly is a recurring feature and unlikely to represent an impending reversal of the Earth's magnetic field.
The South Atlantic Anomaly is an area characterized by a significant reduction in the strength of Earth's magnetic field compared with areas at similar geographic latitudes. Here, protection from harmful radiation from space is reduced. The most significant signs of this are technical malfunctions aboard satellites and spacecraft.
The geomagnetic records from the rocks covering 34 different volcanic eruptions that took place between eight and 11 million years ago revealed that at these occurrences the direction of the magnetic field for St Helena often pointed far from the North pole, just like it does today.
The Earth's magnetic field, or the geomagnetic field, not only gives us the ability of navigating with a compass, but also protects our atmosphere from charged particles coming from the sun, called solar wind. However, it is not completely stable in strength and direction, both over time and space, and it has the ability to completely flip or reverse itself with substantial implications.
The South Atlantic Anomaly is a topic of debate between scientists in this field. Besides the fact that it causes damages to space technology, it also raises the question of where it comes from and whether it represents the start of the total weakening of the field and a possible upcoming pole reversal.
study provides the first long term analysis of the magnetic field in this region dating back millions of years. It reveals that the anomaly in the magnetic field in the South Atlantic is not a one-off, similar anomalies existed eight to 11 million years ago.
"This is the first time that the irregular behaviour of the geomagnetic field in the South Atlantic region has been shown on such a long timescale. It suggests that the South Atlantic Anomaly is a recurring feature and probably not a sign of an impending reversal.
"It also supports earlier studies that hint towards a link between the South Atlantic Anomaly and anomalous seismic features in the lowermost mantle and the outer core. This brings us closer to linking behaviour of the geomagnetic field directly to features of the Earth's interior"
Elevated paleomagnetic dispersion at Saint Helena suggests long-lived anomalous behavior in the South Atlantic, Proceedings of the National Academy of Sciences (2020). DOI: 10.1073/pnas.2001217117
