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!"

Gold nanoparticles to save neurons from cell death
In a recent experiment, researchers have developed gold nanoparticles in the laboratory in order to reduce the cell death of neurons exposed to overexcitement.
Excessive stimulation of neurons by the neurotransmitter glutamate, which is usually involved in the excitatory communication among neurons, can damage nerve cells and cause their degeneration. This phenomenon, known with the term excitotoxicity, is common in many neuroinflammatory and neurodegenerative diseases, such as Alzheimer's and Huntington's disease, but also in case of epilepsy, brain trauma and stroke.
In particular, these nanoparticles were designed and prepared by a IIT team in Lecce (Italy), and are functionalized with peptides that allow selective inhibition of extrasynaptic glutamate receptors involved in the excitotoxicity. In fact, the size of the nanoparticles is 20, which is 50 times larger than that of classic drugs resulting in the blockade of only the receptors located outside the synapses. In this way, correct neurotransmission is preserved while the excessive activation that leads to cell death is avoided.
The molecular mechanism underlying the neuroprotective effect of the nanoparticles has been clarified by the experimental work.
The results of this research sets the basis for treatment of neurological diseases in which the excessive release of glutamate is at the basis of the pathology. The possibility of specifically blocking extrasynaptic receptors, mainly responsible for cell death, without interfering with synaptic transmission, opens up promising perspectives for targeted therapy without major side effects.
This study shows how nanotechnology can provide important indications for treatment of many neuroinflammatory and neurodegenerative diseases.

Light harvesting is the collection of solar energy by protein-bound chlorophyll molecules. In photosynthesis—the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water—light energy harvesting begins with sunlight absorption.
Newly created model by researchers now shows that by absorbing only very specific colors of light, photosynthetic organisms may automatically protect themselves against sudden changes—or 'noise'—in solar energy, resulting in remarkably efficient power conversion.
Green plants appear green and purple bacteria appear purple because only specific regions of the spectrum from which they absorb are suited for protection against rapidly changing solar energy.

What if taking your blood pressure medication could be as simple as eating a spoonful of rice? And if this "treatment" could also have fewer side effects than current blood pressure medicines? Who wouldn't like it?
As a first step, researchers have made transgenic rice that contains several anti-hypertensive peptides. When given to hypertensive rats, the rice lowered their blood pressure.
A common class of synthetic drugs used to treat hypertension, called ACE inhibitors, target the angiotensin converting enzyme (ACE), which is involved in blood pressure regulation. However, ACE inhibitors often have unpleasant side effects, such as dry cough, headache, skin rashes and kidney impairment. In contrast, natural ACE inhibitors found in some foods, including milk, eggs, fish, meat and plants, might have fewer side effects. But purifying large amounts of these ACE-inhibitory peptides from foods is expensive and time-consuming. So researchers wanted to genetically modify rice—one of the world's most commonly eaten foods—to produce a mixture of ACE-inhibitory peptides from other food sources.
The researchers introduced a gene to rice plants that consisted of nine ACE-inhibitory peptides and a blood-vessel-relaxing peptide linked together, and confirmed that the plants made high levels of the peptides. The researchers then extracted total protein (including the peptides) from the transgenic rice and administered them to rats. Two hours after treatment, hypertensive rats showed a reduction in blood pressure, while rats treated with wild-type rice proteins did not. Treatment of rats over a 5-week period with flour from the transgenic rice also reduced blood pressure, and this effect remained 1 week later. The treated rats had no obvious side effects in terms of growth, development or blood biochemistry. If these peptides have the same effects in humans, a 150-pound adult would need to eat only about half a tablespoon of the special rice daily to prevent and treat hypertension, the researchers say.

Forensic science: Bringing burnt bones back to life using 3-D technology
Forensic scientists at the University of Portsmouth have discovered a new way of presenting fragile evidence, by reconstructing a 'jigsaw' of human bone fragments using 3-D printing.
In the first known study of its kind, researchers took fragmented burnt human bones and tested the ability to make 3-D models suitable to be shown to a jury in court.
Forensic investigation of crime scenes and other incidents requires the analysis of many different items as evidence, including human remains, some of which may be damaged or fragmented. To determine whether these pieces of evidence were originally one whole, they have to undergo a process called 'physical fit analysis'.
A positive physical fit indicates that two or more fragments having originated from the same object. Confirming physical fit at a crime scene is essential to draw links between locations, place suspects at the scene, and allow for object reconstruction."
However, physical fit analysis relies on the manual handling and then placing back together of the human remains and is often challenging to conduct with bone fragments particularly when fragile, sharp, or embedded in other materials.
The scientists compared two different 3-D imaging techniques, micro computed tomography and structured light scanning. By generating virtual 3-D models and prints of burned human bone fragments, they tested the suitability of these imaging techniques and subsequent 3-D printing for physical fit analysis. The researchers ultimately found that 3-D imaging and printing allowed for effective physical fit analysis without excessively handling the original fragments.
Limiting the handling of fragile forensic evidence minimizes damage and contamination. Additionally, the use of 3-D prints opens up the possibility for physical fit demonstration, and the opportunity for a jury to explore the evidence replicas. Interaction with 3-D virtual models and animations also provides 360 degree visualization in an engaging, understandable and potentially impactful way, improving a jury's understanding.
