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!"

Only 40% of preprints by researchers in lower-income countries will even..., compared with 61% authored by researchers in high-income nations. An analysis of almost 140,000 papers posted on the preprint servers bioRxiv and medRxiv between their inception (in 2013 and 2019, respectively) and 2021 also found that when a researcher in a richer country was added to the author list, the preprint-to-paper conversion rate increased. A lack of financial resources in poorer regions is likely to be one of the key factors preventing the transition from preprint to paper.

The study looked at observational and climate model data between 1960 and 2014, and then at projections for 2045 to 2099.
Researchers first looked at the impact of the jet stream—the air currents that drive weather patterns in many of the world's most important crop producing regions.
They found that a "strong meandering" of the jet stream, flowing in big wave shapes, has particularly significant impacts on key agricultural regions in North America, Eastern Europe and East Asia, with a reduction in harvests of up to seven percent.
The researchers also found that this had been linked to simultaneous crop failures in the past.
One example was in 2010, when the fluctuations of the jet stream were linked to both extreme heat in parts of Russia and devastating floods in Pakistan, which both hurt crops.
The study also looked at how well computer models assess these risks and found that while they are good at showing the atmospheric movement of the jet stream, they underestimate the magnitude of the extremes this produces on the ground.

The risks of harvest failures in multiple global breadbaskets have been underestimated, according to a study that researchers said should be a "wake up call" about the threat climate change poses to our food systems.
Food production is both a key source of planet-warming emissions and highly exposed to the effects of climate change, with climate and crop models used to figure out just what the impacts could be as the world warms.
In the new research published in Nature Communications, researchers looked at the likelihood that several major food producing regions could simultaneously suffer low yields. These events can lead to price spikes, food insecurity and even civil unrest, according to them.
By "increasing the concentration of greenhouse gases, we are entering this uncharted water where we are struggling to really have an accurate idea of what type of extremes we're going to face," according to them. These types of concurring events are really largely underestimated.

For the first time in the world researchers have encoded a toxin produced by bacteria into mRNA (messenger RNA) molecules and delivered these particles directly to cancer cells, causing the cells to produce the toxin—which eventually killed them with a success rate of 50%.
Many bacteria secrete toxins. The most famous of these is probably the botulinum toxin injected in Botox treatments. Another classic treatment technique is chemotherapy, involving the delivery of small molecules through the bloodstream to effectively kill cancer cells. However, chemotherapy has a major downside: it is not selective, and also kills healthy cells. The idea of this work was to deliver safe mRNA molecules encoded for a bacterial toxin directly to the cancer cells—inducing these cells to actually produce the toxic protein that would later kill them. It's like placing a Trojan horse inside the cancer cell.
First, the research team encoded the genetic info of the toxic protein produced by bacteria of the pseudomonas family into mRNA molecules (resembling the procedure in which genetic info of COVID-19's spike protein was encoded into mRNA molecules to create the vaccine).
The mRNA molecules were then packaged in lipid nanoparticles coated with antibodies—to make sure that the instructions for producing the toxin would reach their target, the cancer cells. The particles were injected into the tumors of animal models with melanoma skin cancer. After a single injection, 44–60% of the cancer cells vanished.
When the cancer cell reads the 'recipe' at the other end it starts to produce the toxin as if it were the bacteria itself and this self-produced toxin eventually kills it. Thus, with a simple injection to the tumor bed, scientists can cause cancer cells to 'commit suicide,' without damaging healthy cells. Moreover, cancer cells cannot develop resistance to this technology as often happens with chemotherapy—because we can always use a different natural toxin.

A study has investigated a seemingly contradictory phenomenon of sleep deprivation leading to mood improvement in patients with depressive disorders.
In a paper, "Enhanced amygdala–cingulate connectivity associates with better mood in both healthy and depressive individuals after sleep deprivation," published in PNAS, the research team mapped brain region activity through resting-state-functional magnetic resonance imaging to see why some people receive a healthy boost from an otherwise negative public health epidemic.
The study finds that one night of total sleep deprivation enhanced amygdala connectivity to the anterior cingulate cortex, which correlated with better mood in some healthy and depressed individuals.

Research into the effectiveness of COVID-19 vaccines in people with lymphoma has shown that repeated vaccination increases their ability to prevent infection from the virus, particularly after four doses.
The finding, from the two-year PROSECO study, is important because blood cancer patients have compromised immune systems—either as a result of cancer, or from cancer treatments. This leaves them more vulnerable to COVID-19 than other people and raises questions over how well they respond to vaccination. Latest findings from the study are published in the journal The Lancet.

A group led by researchers at Nagoya University in Japan has developed a technology to capture and release cell-free DNA (cfDNA) on nanowire surfaces from urine. By extracting this DNA, they were able to successfully detect IDH1 mutation, a characteristic genetic mutation of gliomas, a type of brain tumor. Their findings increase the effectiveness of cancer detection tests using urine. They published their results in the journal Biosensors and Bioelectronics.
Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein's expanding universe. The research is published in Nature Astronomy.
Einstein's general theory of relativity means that we should observe the distant—and hence ancient—universe running much slower than the present day. However, peering back that far in time has proven elusive. Scientists have now cracked that mystery by using quasars as "clocks."
Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower, according to these scientists.
If you were there, in this infant universe, one second would seem like one second—but from our position, more than 12 billion years into the future, that early time appears to drag.
Researchers used observed data from nearly 200 quasars—hyperactive supermassive black holes at the centers of early galaxies—to analyze this time dilation.
Thanks to Einstein, we know that time and space are intertwined and, since the dawn of time in the singularity of the Big Bang, the universe has been expanding. This expansion of space means that our observations of the early universe should appear to be much slower than time flows today. In this new study, scientists have established that back to about a billion years after the Big Bang.
Previously, astronomers have confirmed this slow-motion universe back to about half the age of the universe using supernovae—massive exploding stars—as "standard clocks." But while supernovae are exceedingly bright, they are difficult to observe at the immense distances needed to peer into the early universe.
By observing quasars, this time horizon has been rolled back to just a tenth the age of the universe, confirming that the universe appears to speed up as it ages.
---
Where supernovae act like a single flash of light, making them easier to study, quasars are more complex, like an ongoing firework display.
What we have done is unravel this firework display, showing that quasars, too, can be used as standard markers of time for the early universe.

A journey to study dark matter and dark energy
ESA’s Euclid mission was launched into space on a SpaceX Falcon 9 from Cape Canaveral in Florida, USA, on 1 July 2023. It is now on its way to Sun-Earth Lagrange point L2. By observing billions of galaxies out to 10 billion light-years, the space telescope will create the most detailed 3D-map of the Universe, with time as the third dimension.
Ultimate Predators |
Humans capture more terrestrial vertebrate species for medicine, the exotic pet trade and other uses than we do for food, according to a new study of how humans affect species’ extinction risk. Humans target some 15,000 vertebrate species, amounting to one thir....
Why this matters: Our ecological impact, the researchers found, is 1,300 times larger than that of comparable predators (wolves, bears). When they assessed species by habitat type, they found that humans have the greatest impact on the ocean. What the experts say: The findings are clear evidence that humans are novel predators. If anything the study’s conclusions are conservative, says Kaitlyn Gaynor an ecologist at the University of British Columbia. “We of course don’t have perfect information on every single species that people are using,” she says.

Exploding populations of wild pigs and macaque monkeys in Southeast Asia are threatening native forests and disease outbreaks in livestock and people, according to research published in Biological Reviews.
Macaques and wild pigs are taking over Southeast Asia's disturbed forests.
Humans are largely to blame for this by altering forests with logging and establishing palm oil farms which provide food and ideal breeding conditions for these animals.
We saw that wild boar and macaque numbers were 400% higher in forests near the plantations than in untouched environments.
These animals take full advantage of the farmland, raiding crops and thriving on calorie‐rich foods.
There were significant human health risks in the rising pig and macaque populations.
The wildlife origins of the COVID-19 pandemic show that mammals in human-modified ecosystems often host high pathogen loads and pose serious zoonotic disease risks. Both pigs and macaques are recognized as carriers of diseases that can be transmitted to people and they're the most common species in a region considered to be the global zoonotic disease hotspot.
