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!"

Self-watering soil could transform farming
A new type of soil created by engineers can pull water from the air and distribute it to plants, potentially expanding the map of farmable land around the globe to previously inhospitable places and reducing water use in agriculture at a time of growing droughts.
The team's atmospheric water irrigation system uses super-moisture-absorbent gels to capture water from the air. When the soil is heated to a certain temperature, the gels release the water, making it available to plants. When the soil distributes water, some of it goes back into the air, increasing humidity and making it easier to continue the harvesting cycle.

Biologists shed light on mystery of how microbes evolve and affect hosts
researchers have found that as microbes evolve and adapt to their unique hosts, they become less beneficial to hosts of other genotypes.
The findings suggest that there is probably not one universally healthy microbiome. Rather, transplanted microbes might need time to adapt to a new host before they bring benefits. Microbes became better adapted to their hosts through the evolution of more, rather than less, cooperation.
Rebecca T. Batstone et al, Experimental evolution makes microbes more cooperative with their local host genotype, Science (2020). DOI: 10.1126/science.abb7222

When we put microbes from the beginning and the end of the experiment back onto hosts, we found they did best with the same hosts they evolved on, suggesting they adapted to their local host," said Batstone. "The derived microbes were more beneficial when they shared an evolutionary history with their host."
The researchers say the finding suggests that evolution might favour cooperation and that scientists might be able to use experimental evolution in a laboratory setting to make microbes that provide more benefits to their hosts.
"When plants or even animals arrive in new environments, perhaps as invasive species or because they are responding to a changing climate, the microbes they encounter may be initially poor partners. But these microbes might rapidly adapt and develop a more beneficial relationship

Your favourite music can send your brain into a pleasure overload
About half of people get chills when listening to their favourite music. Neuroscientists based in France have now used EEG to link chills to multiple brain regions involved in activating reward and pleasure systems.
Scientists tried to understand why this happens. When the participants experienced a chill, researchers saw specific electrical activity in the orbitofrontal cortex (a region involved in emotional processing), the supplementary motor area (a mid-brain region involved in movement control) and the right temporal lobe (a region on the right side of the brain involved in auditory processing and musical appreciation). These regions work together to process music, trigger the brain's reward systems, and release dopamine—a "feel-good" hormone and neurotransmitter. Combined with the pleasurable anticipation of your favourite part of the song, this produces the tingly chill you experience—a physiological response thought to indicate greater cortical connectivity.
When experiencing musical chills, low frequency electrical signals called "theta activity"—a type of activity associated with successful memory performance in the context of high rewards and musical appreciation—either increase or decrease in the brain regions that are involved in musical processing.
What is most intriguing is that music seems to have no biological benefit to us. However, the implication of dopamine and of the reward system in processing of musical pleasure suggests an ancestral function for music.
This ancestral function may lie in the period of time we spend in anticipation of the "chill-inducing" part of the music. As we wait, our brains are busy predicting the future and release dopamine. Evolutionarily speaking, being able to predict what will happen next is essential for survival.
Why should we continue to study chills?
Researchers want to measure how cerebral and physiological activities of multiple participants are coupled in natural, social musical settings. Musical pleasure is a very interesting phenomenon that deserves to be investigated further, in order to understand why music is rewarding and unlock why music is essential in human lives.

Man Almost Dies From an Allergic Reaction to Cold Air After a Shower
Stepping out of a hot shower into a cold bathroom almost killed a Colorado man, who had developed a serious allergic reaction to cold temperatures.
The 34-year-old old man collapsed after getting out of the shower, and his family found him on the floor, according to a report of the case published October 27 in The Journal of Emergency Medicine.
The man was struggling to breathe and his skin was covered in hives. He was experiencing a life-threatening, whole-body allergic reaction known as anaphylaxis.
When paramedics arrived, his family told them that the man had a history of being "allergic to the cold weather", according to the report. He had previously experienced hives as a reaction to the cold, but not anaphylaxis.
These episodes started after he moved from Micronesia, which has a tropical climate, to Colorado, which sees colder temperatures, the report said.
Paramedics treated the man with epinephrine and oxygen, and rushed him to the emergency room. When he got to the hospital, he was sweating profusely and had hives all over his body.
Doctors diagnosed him with cold urticaria, an allergic reaction of the skin after exposure to cold temperatures, including cold air or cold water, according to the Mayo Clinic. People can also develop symptoms after consuming cold food or drinks, Live Science previously reported.
The most common symptom is a red, itchy rash (hives) after exposure to the cold; but in more serious cases, people can develop anaphylaxis, which can cause their blood pressure to plummet and airways to narrow, making breathing difficult.
These more severe reactions typically occur with full-body skin exposure to the cold, such as when people swim in cold water, the Mayo Clinic says. In the man's case, his entire body was exposed to cold air after stepping out of his shower.
Doctor's confirmed the man's diagnosis using an 'ice cube test', which involves placing an ice cube on the skin for about 5 minutes. If the patient develops a raised, red bump on the skin where the ice cube was, they are diagnosed with cold urticaria.

Drones Are Being Sent Straight Into Volcanoes, For Life-Saving Science
With an estimated 300 active volcanoes on Earth, the challenge is how to monitor them all to send out early warnings before they erupt. Measuring volcanic gas emissions is also no easy task.
Now researchers have designed specially-adapted drones to help gather data from an active volcano in Papua New Guinea (PNG).
Scientists have a few ways of forecasting when a volcano is going to blow. They can monitor earthquake activity in the area to detect tremors which almost always precede eruptions, and look out for bulging in the volcano's sloping walls as magma builds up underneath.
When clear skies allow, satellites can also rapidly detect and measure volcanic emissions of gases such as sulphur dioxide (SO2). Changes to these gas emissions can signal more activity in the volcano below.
Although volcanoes emit just a fraction of the carbon emissions humans do, researchers still want to be able to estimate what carbon dioxide (CO2) they do emit, to factor this into the carbon budget we have left to limit the effects of climate change.
Travelling to PNG, the international team set about testing two types of long-range drones equipped with gas sensors, cameras, and other devices during two field campaigns.
novel approach - that is, long-range and high-altitude [drone] operations enabling in situ measurements - is presently the only feasible means by which we can characterise gas chemistry at steep, hazardous, and highly active volcanoes like Manam," the research team concluded in their paper.
Future research will take more diligent work from scientists and flying time from drones, since the measurements from this study spanned just 10 days.

Antibiotic study wins research paper of the year
The paper, published in the New England Journal of Medicine in July 2019 and led by Cardiff University, in collaboration with Kings and the University of Oxford, has been awarded the prestigious honour from the Royal College of General Practitioners (RCGP). The paper found a finger-prick blood test could help prevent unnecessary prescribing of antibiotics for people with chronic obstructive pulmonary disease (COPD). The finger prick test measures the amount of C-reactive protein (CRP). This is a marker of inflammation that rises rapidly in the blood in response to serious infections. People who have a low CRP level can receive little benefit from antibiotic treatment. Testing the blood levels can safely reduce the use of antibiotics.

Novel biomarker and modelling could help better identify lethal arrhythmias
Researchers at the School of Biomedical Engineering & Imaging Sciences at Kings College London, in collaboration with colleagues at the Royal Brompton & Hartfield NHS Foundation Trust, have identified a novel imaging-biomarker that can be used to help differentiate risk levels of lethal arrhythmias (irregular heartbeat) in patients with problematic left ventricles. For the first time, they have used detailed computational modelling to also understand why this biomarker is important, in the hopes it will help clinical translation and personalise medicine. Published in JACC: Electro Electrophysiology, the researchers also showed that patient-specific computational simulations alone could be used as a predictive tool to identify individual risk of arrhythmias.https://www.kcl.ac.uk/news/novel-biomarker-and-modelling-could-help...

Small brain device proves big game changer for severely paralysed patients
A tiny device the size of a small paperclip has been shown to help patients with upper limb paralysis to text, email and even shop online in the first human trial. The device, Stentrode, has been implanted successfully in two patients, who both suffer from severe paralysis due to motor neuron disease (MND) also known amyotrophic lateral sclerosis (ALS) and neither had complete ability to move their upper limbs. Published in the Journal of NeuroInterventional Surgery, the results found the Stentrode was able to wirelessly restore the transmission of brain impulses out of the body. This enabled the patients to successfully complete daily tasks such as online banking, shopping and texting, which previously had not been available to them.
