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!"

Smoke from major wildfires destroys the ozone layer, study shows
A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.
Atmospheric chemists found that smoke from the Australian wildfires of 2019 and 2020 destroyed atmospheric ozone in the Southern Hemisphere for months. The ozone shield is a part of the stratosphere layer of the Earth's atmosphere that absorbs UV rays from the sun.
The researchers used data from the Canadian Space Agency's Atmospheric Chemistry Experiment (ACE) satellite to measure the effects of smoke particles in the stratosphere. The results appear in the journal Science.
The Australian fires injected acidic smoke particles into the stratosphere, disrupting the chlorine, hydrogen and nitrogen chemistry that regulate ozone. This is the first large measurement of the smoke, which shows it converting these ozone-regulating compounds into more reactive compounds that destroy ozone.
Similar to the holes over polar regions, this damage is a temporary effect, and the ozone levels returned to pre-wildfire levels once the smoke disappeared from the stratosphere. But an increase in the prevalence of wildfires would mean the destruction happens more often.
The lead author on the paper is Dr. Paula Byrne from the HRB Centre for Primary Care Research based in RCSI's Department of General Practice. Commenting on the findings, Dr. Byrne says that "the message has long been that lowering your cholesterol will reduce your risk of heart disease, and that statins help to achieve this. However, our research indicates that, in reality, the benefits of taking statins are varied and can be quite modest."
The researchers go on to suggest that this updated information should be communicated to patients through informed clinical decision-making and updated clinical guidelines and policy.
This important discovery was a collaboration with Professor Susan M Smith, also of RCSI and with researchers from the University of New Mexico, USA, (Dr. Robert DuBroff), the Institute for Scientific Freedom in Denmark (Dr. Maryanne Demasi), Bond University in Australia (Dr. Mark Jones) and independent researcher Dr. Kirsty O'Brien.

New research from RCSI University of Medicine and Health Sciences has revealed that the link between 'bad' cholesterol (LDL-C) and poor health outcomes, such as heart attack and stroke, may not be as strong as previously thought.
Published in JAMA Internal Medicine, the research questions the efficacy of statins when prescribed with the aim of lowering LDL-C and therefore reducing the risk of cardiovascular disease (CVD).
Previous research has suggested that using statins to lower LDL-C positively affects health outcomes, and this is reflected in the various iterations of expert guidelines for the prevention of CVD. Statins are now commonly prescribed by doctors, with one third of Irish adults over the age of 50 taking statins, according to previous research.
The new findings contradict this theory, finding that this relationship was not as strong as previously thought. Instead, the research demonstrates that lowering LDL-C using statins had an inconsistent and inconclusive impact on CVD outcomes such as myocardial infarction (MI), stoke, and all-cause mortality.
In addition, it indicates that the overall benefit of taking statins may be small and will vary depending on an individual's personal risk factors.

Marine sponges are incredible sources of structurally diverse and biologically active natural products. The development of secondary metabolites isolated from sponges into FDA approved drugs is well precedented, with representative examples such as the antiviral nucleoside, vidarabine, and the potent anticancer drug, eribulin mesylate, used in treatment of late-stage, metastatic breast cancer. Despite these success stories, the pharmaceutical industry has largely abandoned efforts to identify bioactive compounds from sponges due to challenges associated with the sustainable sourcing of raw material for extraction, chemical modification of intricate architectures, and overall lack of precedent regarding how sponges assemble these secondary metabolites. The San Diego intertidal and subtidal zones are home to an incredibly rich taxonomic diversity of sponges, presenting a unique opportunity to apply modern genomic and metabolomic approaches to identify new, bioactive scaffolds and decrypt their biosynthetic origin. We profiled over 20 species of sponges local to San Diego using classical and feature-based molecular networking, as well as examined the variation of microbial symbionts across phyla using culture-dependent and independent methods. Our access to fresh, local samples enabled our identification of a variety of novel, bioactive compounds and glean new insights into their genetic origin and environmental role in host-microbe interactions.
Copper is an essential element of life from bacteria and fungi to plants and animals. In humans, it binds to enzymes to help blood clot, hormones mature, and cells process energy. But too much copper kills cells—and now scientists have figured out how.
Copper is a double-edged sword: too little and cells can't survive. But too much, and cells die.
Researchers have uncovered a new form of cell death that is induced by copper.
found that copper binds to specialized proteins, causing them to form harmful clumps, and also interferes with the function of other essential proteins. Cells go into a state of toxic stress and ultimately die.
By shedding light on key components of this process, the research also identified which cells are particularly vulnerable to copper-induced death. The findings could help researchers better understand diseases in which copper is dysregulated, and could even inform the development of new cancer treatments.

Researchers have discovered a new form of ice, redefining the properties of water at high pressures.
Solid water, or ice, is like many other materials in that it can form different solid materials based on variable temperature and pressure conditions, like carbon forming diamond or graphite. However, water is exceptional in this aspect as there are at least 20 solid forms of ice known to us.
A team of scientists pioneered a new method for measuring the properties of water under high pressure. The water sample was first squeezed between the tips of two opposite-facing diamonds—freezing into several jumbled ice crystals. The ice was then subjected to a laser-heating technique that temporarily melted it before it quickly re-formed into a powder-like collection of tiny crystals.
By incrementally raising the pressure, and periodically blasting it with the laser beam, the team observed the water ice make the transition from a known cubic phase, Ice-VII, to the newly discovered intermediate, and tetragonal, phase, Ice-VIIt, before settling into another known phase, Ice-X.
the transition to Ice-X, when water stiffens aggressively, occurs at much lower pressures than previously thought.
While it's unlikely we'll find this new phase of ice anywhere on the surface of Earth, it is likely a common ingredient within the mantle of Earth as well as in large moons and water-rich planets outside of our solar system.

Once the cells had settled in, the researchers induced several models of acute inflammation, including stroke and chemically induced meningoencephalitis.
They found that the skull contributed significantly more neutrophils to the brain in the event of stroke and meningitis than the tibia. But that raised a new question – how were the neutrophils being delivered?
Unexpectedly scientists discovered tiny channels that connected the marrow directly with the outer lining of the brain!
Using organ-bath microscopy – which uses a chamber full of solution to maintain the integrity of the isolated tissue while it is being examined – the team imaged the inner surface of a mouse's skull. There, they found microscopic vascular channels directly connecting the skull marrow with the dura, the protective membrane that encases the brain.

Did you know you have tiny tunnels in your head? That's OK, no one else did either until recently! But that's exactly what a team of medical researchers confirmed in mice and humans in 2018 – tiny channels that connect skull bone marrow to the lining of the brain.
The research shows they may provide a direct route for immune cells to rush from the marrow into the brain in the event of damage.
Previously, scientists had thought immune cells were transported via the bloodstream from other parts of the body to deal with brain inflammation following a stroke, injury, or brain disorder.
This discovery suggests these cells have had a shortcut all along.
The tiny tunnels were uncovered when a team of researchers set out to learn whether immune cells delivered to the brain following a stroke or meningitis originated from the skull, or the larger of the two bones in the shin – the tibia.
The specific immune cells they followed were neutrophils, the "first responders" of the immune squad. When something goes awry, these are among the first cells the body sends to the site to help mitigate whatever is causing the inflammation.
The team developed a technique to tag cells with fluorescent membrane dyes that act as cell trackers. They treated these cells with the dyes, and injected them into bone marrow sites in mice. Red-tagged cells were injected into the skull, and green-tagged cells into the tibia.

Moving forward, the researchers aim to identify the specific compounds in the neem bark that are responsible for the antiviral effects. That could help guide the development of neem-based antiviral therapies and determining the dosage requirements for treating coronavirus infections.
“The antiviral properties of neem bark extract offer a new premise for restricting viral spread, replication and fusion. Our studies can guide new antiviral therapeutic efforts to combat the ongoing COVID-19 pandemic and hold promise for treating the future emergence of new coronavirus strains,” the authors wrote.
