All children by nature, are keen to learn..
Pablo Picasso once declared “ Every child is an artist. The problem is how to remain an artist once we grow up”.
A combined study in Cognition by M.I.T & Stanford University states that, every child is a natural scientist too.
So, it is simple, we just remain eager, enthusiastic and continue to discover, learn and share. " All children are scientists somehow that gets lost ” says Dr. Lydia Villa-Komaroff, a Mexican-American woman who is a world renowned molecular biologist whose research has contributed greatly to medical science Learn more..

firefly algorithm
Fireflies here in America tend to ignore each other doing their own thing flashing paying no attention to others. But in Southeast Asia places like Malaysia, Thailand, Indonesia male fireflies have a tendency towards spontaneous order, they flash in perfect time together in synchrony. Firefly swarms are made of relatively unsophisticated individuals, they exhibit coordinated behavior that directs the swarms to their desired goals. This usually results in the self organized behavior as a whole, and collective intelligence or swarm intelligence. Crickets and frogs communicate with cyclic sound much as fireflies do with cyclic light. Sometimes these sounds can spontaneously synchronize within a species in a process that is similar to how fireflies synchronize their flashes. Biological synchronization is not limited to insects and amphibians. The cells that make up the human heart's natural pacemaker, the rhythm keeper that controls the electrical signals that cause the heart to pump, display a propensity for spontaneous synchronization. Each cell can be thought of as an individual oscillator, in much the same way that a firefly can Learn more..
why ants don't need ant-man as their leader..

Happy Women's Day!
|
In Ant-man Dr. Henry "Hank" Pym, remarks that ants can perform amazing feats, but they need a leader to tell them what to do. Pym wears a small device behind his ear that allows him to instruct the ants, it’s wrong. Ants never march in lockstep, united in obedience to a single command. In the real world, the often random and apparently inept actions of individual ants, each without any sense of a common goal, combine to allow colonies to find and collect food, build nests, form trails and bridges, defend their host plants from herbivores or cultivate gardens—all without supervision. Neither the queen nor any other ant can assess what needs to be done and give orders to others Learn more..

"Feet, what do I need them for if I have wings to fly?" says Frida Kahlo, an awesome Mexican artist. International Women's Day means different things to different people, but the global focus on equality and celebration is clear. Throughout ancient and modern history, women have collaborated and lead purposeful action to redress inequality in the hope of a better future for their communities, children and themselves. Whether through bold well-documented action or through humble resistance that never made it into the history books, women have united for equality and achievement forever. And along the way, one particularly powerful collaboration lead to the formation of a globally united moment for women across countries to come together in hope and action. That moment is "International Women's Day". Started in the early 1900's, the almighty and tenacious Suffragettes forged purposeful action for equality Learn more..

what is hachi - moji dna (eight-letter DNA in Japanese)
|
why is 2019 a common year? |
In 1942, Schrödinger predicted that no matter what genetic polymer life uses, its informational building blocks must all have the same shape and size. Hachimoji meets this prediction. Scientists have successfully added four new bases to create what they are calling “hachi-moji DNA”. The synthetic DNA includes the four nucleotides present in Earth life, but also four others that mimic the structures of the informational ingredients in regular DNA. Hachi-moji DNA uses hydrogen bonds just like natural DNA to link its two new pairs--S with B and P with Z—and the bases are also capable of appearing next to each other. Because DNA is read in triplets of bases called codons, each of which codes for a particular amino acid, this significantly increases the number of potential codons compared to the previous approach: 512 compared to conventional DNA’s 64. The bases pair reliably, the structure remains stable regardless of the sequence of bases, and they’ve demonstrated that it can be copied into RNA learn more..

The reason for adding leap days to the calendar is to align the calendar year with the actual year – which is defined by the time it takes Earth to circle the sun. It is equal to 365 days, 5 hours, 48 minutes and 46 seconds, or 365.24219 days. However, the Gregorian calendar has only 365 days in a year, so if we didn't add a leap day on February 29 nearly every four years, we would lose almost six hours off our calendar every year. After only 100 years, our calendar would be off by around 24 days Learn more..

today in history : the first mass inoculation started
|
why are we not totally immune to virus & bacteria?
|
Today in 1954, the first mass inoculation of schoolchildren against polio using the Salk vaccine began in Pittsburgh as some 5,000 students were vaccinated. Polio is the common name for poliomyelitis, which comes from the Greek words for grey and marrow, referring to the spinal cord, and the suffix –itis, meaning inflammation. Poliomyelitis, shortened, became polio. For a time, polio was called infantile paralysis, though it did not affect only the young. Salk conducted the first human trials on former polio patients and on himself and his family, and by 1953 was ready to announce his findings. Adults were also often afflicted, including future president Franklin D. Roosevelt, who in 1921 was stricken with polio at the age of 39 and was left partially paralyzed. (After FDR's death, physicians argued that he actually suffered from Guillain-Barre Syndrome. It could be the most famous misdiagnosis in history). 'To educate a man in mind, and not in morals is to educate a menace to society' said President Theodore Roosevelt. Without guiding principles one will not have a moral compass. With no moral compass, all paths will seem of near equal value. On the flip side: When asked who owned the patent on his vaccine against polio virus, Jonas Salk responded Learn more..

We are constantly under assault by pathogenic infectious microorganisms. Synthetic drugs that are available according to CDC are (antiviral drugs) baloxavir marboxil (Xofluza), oseltamivir (Tamiflu), and zanamivir (Relenza) for both flu prevention and treatment. Thankfully, more than 1 billion years of evolution have equipped most multi-cellular life with a host of methods to intercept and destroy invading pathogens: by two distinct protective schemes: innate and adaptive immunity. Of the two methods, the adaptive immunological response is the most well-known and extensively studied. Adaptive or acquired immunity, present in most vertebrate animals. Historically, innate immunity has not enjoyed the same deep level of interest and study as the adaptive immunological response Learn more..

Patterns in nature
|
treat failure like a scientist: as another data point
|
Nature is full of biological regularity the rows of an alligator’s teeth, the stripes on a zebra fish, the spacing of a chicken’s feathers. How do these patterns arise? Think the stripes on a zebra. The stripes are a bold pattern but are not exactly symmetrical. Everyone can recognize that as a pattern, but no stripe is like any other stripe. Other times, it’s much more subtle but once you notice it, it’s clearly evident – like a lizard’s skin. A tiger's stripes (a pattern) is a strategy to blend in with shadows in grasslands and forest. Another system we find cropping up again and again in different places, both in the living and the nonliving world, is a pattern that we now call Turing structures. Yep! they are named after Alan Turing, the mathematician who laid the foundation for the theory of computation. He was very interested in how patterns form. In particular, he was interested in how that happens in a fertilized egg, which is basically a spherical cell that somehow gets patterned into something as complicated as a human as it grows and divides Learn more..

How does a scientist treat failure? And what can we learn from their approach? When a scientist runs an experiment, there are all sorts of results that could happen. Some results are positive and some are negative, but all of them are data points. Each result is a piece of data that can ultimately lead to an answer and that’s exactly how a scientist treats failure: as another data point. This is much different than how society often talks about failure. For most of us, failure feels like an indication of who we are as a person ( Failing a test means you’re not smart enough. Failing to get fit means you’re undesirable. Failing at art means you’re not creative. And so on) Learn more..

Quaternions:
The discovery of quaternion algebra, a discovery made by an Irish man, who graffitied his idea on a bridge along the Royal Canal in the 19th century. William Rowan Hamilton was born in Dublin in 1805. He became interested in mathematics when he lost a competition against an American child, Zerah Colburn, who was incredibly quick at computing numbers. While Hamilton was interested in many subjects, this polymath pursued his interest in math and chose to study classics and science in Trinity College Dublin, where he later became a professor of astronomy. Hamilton was fascinated by the link between geometry and complex numbers. Complex numbers are numbers that are made up of a real number (numbers we’re used to dealing with in everyday life to count or measure, like a temperature of -4 degrees) and an imaginary number (which can be written as a real number multiplied by an “imaginary” part, symbolised by “i”) Learn more..

how to think critically?
Critical thinking is the ability to think clearly and rationally, understanding the logical connection between ideas. In essence, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information. Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not. Critical thinkers will identify, analyze and solve problems systematically rather than by intuition or instinct Learn more..

game theory AND Prisoner’s Dilemma:
Game theory has been developed over many years since the term was first coined to what it is now: a theory used to understand the strategic behaviour of decision makers who are aware that their decisions affect one another. Game theory was initially developed by John von Neumann (1903–57) and Oskar Morgenstern (1902–77) in 1944 as a mathematical theory. Following on from this, in 1944 Neumann published The Theory of Games and Economic Behavior co-authored with Morgenstern. This is considered to be one of the main foundation texts of game theory. Despite the theory’s origins dating back to Neumann and Morgenstern’s work, the economists John Nash, John Harsanyi, and Reinhard Selten received the Nobel Prize for Economics in 1994 for further developing game theory in relation to economics. Here are some interesting facts on the field; from its key influencers and terms, to how it applies in everyday life and examples Learn more..

learning to estimate

Costasiella kuroshimae, from the Costasiellidae family is otherwise known as the Sea Sheep. At only 1cm long these tiny slugs are arguably just as cute, and definitely just as cool as sea bunnies. Not only are these slugs absolutely adorable, they come with their own battery packs. Much like land sheep, kuroshimae love munching on greens. However, instead of grass they chew on algae. They love it, so much so that they’ve absorbed the algae into their own bodies! You can see the bright green algae hanging out on the slugs back. It’s a process known as kleptoplasty, where the ingested algae are incorporated into the hosts body and still retain some of their photosynthetic properties. So not only to the sea sheep get a hearty meal they even get to use the algae as their very own power source Learn more..

The so-called “back of the envelope calculations”, were an essential tool for scientists in the pre-computer era, they provided the means to keep track of exponents when using a slide rule.calculations requires mathematical skills, logic, critical thinking, life experiences, and the ability to break down complex problems into smaller discrete, soluble parts. At some point in the solution process, the solver is expected to estimate a value which is critical to obtaining an answer.The methodology, involved in making up a (Fermi) Question as well as calculating an answer. The Fermi Questions event in the Science Olympiad tests a team’s ability to estimate a solution to a problem by interpreting basic information, formulating a set of mathematical operations to provide an answer, and using mathematics to provide the answer to the question. Fundamental to the solution of these problems is a skill called critical thinking - essentially a method of attacking such problems in an orderly, logical way Learn more..

It’s so obvious that it’s practically proverbial: you can’t unboil an egg. But actually, it turns out that you can -- sort of. Eleanor Nelsen explains the process by which mechanical energy can undo what thermal energy has done.

Rather than spending days and weeks putting certain misshapen proteins back together, people in laboratories may be able to stick solutions into 2-by-2 foot machines and be done with it just minutes later, so they can get back to the work of developing cancer treatments

we are surrounded by buttons :: that don't work!
Apparently we are surrounded by buttons that are mechanically sound and can be pushed, but provide no functionality. First: the crosswalk button : When cities switched over to automation using intelligent algorithms to time traffic signals (which meant many crosswalk buttons became shams for at least part of the day). But, according to Ellen Langer, a psychologist who pioneered a concept known as the "illusion of control".. these buttons may still serve a purpose: they have a "psychological effect" on pedestrians. Turns out taking some action leads people to feel a sense of control over a situation, and that feels good, rather than just being a passive bystander. Doing something typically feels better than doing nothing (which explains why people press the elevator call button when it's already lit) Learn more..
what is winter solstice?
Today is the shortest day of 2018 for anyone living in the Northern Hemisphere. Technically, the solstice occurs when the sun is directly over the Tropic of Capricorn, or 23.5° south latitude. In 2018, this will occur today at 5:23 pm Eastern time. The winter and summer solstices, the seasons, and the changing length of daylight hours throughout the year are all due to one fact: Earth spins on a tilted axis. The tilt, possibly caused by a massive object hitting Earth billions of years ago means that for half the year, the North Pole is pointed toward the sun (as in the picture above). For the other half of the year, the South Pole gets more light. It’s why we have seasons Learn more..

cell-sized nano-bots
Tiny robots no bigger than a cell could be mass-produced using a new method developed by researchers at MIT. The microscopic devices, which the team calls “syncells” (short for synthetic cells), might eventually be used to monitor conditions inside an oil or gas pipeline, or to search out disease while floating through the bloodstream. The key to making such tiny devices in large quantities lies in a method the team developed for controlling the natural fracturing process of atomically-thin, brittle materials, directing the fracture lines so that they produce miniscule pockets of a predictable size and shape. Embedded inside these pockets are electronic circuits and materials that can collect, record, and output data Learn more..

The most significant advancement thus far in the field is that of “deep learning,” a subcategory of machine learning that attempts to mimic the way the human brain learns new concepts.

If the number of objects is so large that some of them reside on external storage during the sort, it is called external sorting. The following are internal sorting algorithms: Bucket sort, Bubble sort, Insertion sort, Selection sort, Heapsort, Mergesort Learn more..

Optical Tweezers use light to manipulate microscopic objects as small as a single atom. The radiation pressure from a focused laser beam is able to trap small particles. In the biological sciences, these instruments have been used to apply forces in the pN-range and to measure displacements in the nm range of objects ranging in size from 10 nm to over 100 mm. A laser beam is focused by a high-quality microscope objective to a spot in the specimen plane. This spot creates an "optical trap" which is able to hold a small particle at its center. The forces felt by this particle consist of the light scattering and gradient forces due to the interaction of the particle with the light. Most frequently, optical tweezers are built by modifying a standard optical microscope. These instruments have evolved from simple tools to manipulate micron-sized objects to sophisticated devices under computer control that can measure displacements and forces with high precision and accuracy Learn more..

the serial killer inside of us

The notion of enzymes as biocatalysts was originally presented in 1833 with the discovery of the conversion of starch into sugars catalyzed by diastase. However, it was not until the 20th century that scientists realized their full potential in the context of medicine and technology. Major landmarks were the development of methods for enzyme isolation and purification, the realization that enzymes are proteins with biochemical activity and their characterization using x-ray diffraction technique. Directed evolution has made it possible to cut out the use of many toxic catalysts, providing enzymes for all manner of fields including the development of bio-fuels and the production of pharmaceuticals.

T-killer cell is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected (particularly with viruses), or cells that are damaged in other ways.Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or cancerous cells, without destroying healthy cells surrounding them. For years, the foundations of cancer treatment were surgery, chemotherapy, and radiation therapy. Over the last two decades, targeted therapies that target cancer cells by homing in on specific molecular changes seen primarily in those cells have also cemented themselves as standard treatments for many cancers. But over the past several years, immunotherapy therapies that enlist and strengthen the power of a patient’s immune system to attack tumors Learn More..

anatomy of Franklin's photo 51
When he saw Rosalind Franklin's now-famous image of DNA, James Watson experienced a eureka moment. "The instant I saw the picture my jaw fell open and my pulse began to race," he later recalled. Unlike Watson, the non expert has no such flash of insight upon seeing Franklin's X-ray diffraction image, for it bears little resemblance to the double helix we all know know so well. Fortunately, with a little explanation Photo 51 begins to look less like a Rorschach test open to infinite interpretation and more like what it relly is: a window into the elixir of life Learn more..

Biomaterials are those materials - be it natural or synthetic, alive or lifeless, and usually made of multiple components — that interact with biological systems. Biomaterials are often used in medical applications to augment or replace a natural function. As a science, biomaterials is about fifty years old. The study of biomaterials is called biomaterials science or biomaterials engineering. aditionally, care should be exercised in defining a biomaterial as biocompatible, since it is application-specific Learn more..

M.I.T's Alter Ego:
|
how does P.C.R work? ( Mini or classic )
|
Wearables can now read your mind. When you think a sentence in your head, your brain sends signals to your mouth and jaw. MIT Media Lab's headset (AlterEgo) reads those signals with 92 percent accuracy. AlterEgo is developed by MIT Media Lab. You strap it to your face. You talk to it. It talks to you. But no words are said. You say things in your head, like "what street am I on," and it reads the signals your brain sends to your mouth and jaw, and answers the question for you. The institution explained in its announcement that AlterEgo communicates with you through bone-conduction headphones, which circumvent the ear canal by transmitting sound vibrations through your face bones Learn more..

PCR is acronim for a simple but very useful procedure in molecular biology called the polymerase chain reaction. A PCR machine (or a thermocycler) has test tubes (the DNA mixture of interest are put into these test tubes) and the machine changes the temperature to suit each step of the process. It is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies. In other words, PCR enables you to produce millions of copies of a specific DNA sequence from an initially small sample – sometimes even a single copy. It is a crucial process for a range of genetic technologies and, in fact, has enabled the development of a suite of new technologies Learn more..

why being wrong is a courageous & desirable human trait:
1,200 years before Descartes said his famous quote "I think therefore I am," this guy, St. Augustine, sat down and wrote "Fallor ergo sum" translated to English its: "I err therefore I am." Augustine understood that our capacity to be wrong is NOT some kind of embarrassing defect in the human system, something we can eradicate or overcome. It's totally fundamental to who we are. Most of us will do anything to avoid being wrong. So why do we get stuck in this feeling of being right? Learn more..

Dr. Frances Oldham Kelsey became an American hero for her role in the thalidomide case, celebrated not only for her vigilance, which spared the United States from widespread birth deformities, but also for giving rise to modern laws regulating pharmaceuticals. In 1960, Dr. Kelsey was hired by the FDA in Washington, D.C. At that time, she was one of only seven full-time and four young part-time physicians reviewing drugs for the FDA. One of her first assignments there was to review an application for the drug thalidomide as a tranquilizer and painkiller for pregnant women for morning sickness. Even though it had already been approved in Canada and more than 20 European and African countries, she withheld approval for the drug and requested further studies. Despite pressure from thalidomide’s manufacturer, Kelsey persisted in requesting additional information to explain an English study that documented a nervous system side effect Learn more..

Jeeves, a programming language with privacy baked in. |
The phrase “you’re the product” first appeared in a 1986 speech by President Reagan about the drug war. Perhaps the most disturbing elements of data collection and use are the gray areas, where the morality of how data is being used is questionable and only seem legal because law enforcement is yet to catch up. By now I'm sure you have heard of the University of Cambridge researcher's app called "This is your digital life" which collected information on millions of Americans through Facebook for Cambridge Analytica, the maker of the application Dr Aleksandr Kogan says he did not know his work for Cambridge Analytica in 2014 violated any policies.

When programmers create a feature for an app or a website, even something as simple as a calendar, they should code in protections so the personal information that the feature needs to access such as your location doesn’t slip out onto the Internet. Needless to say, they sometimes fail, leaving our data to be exploited by hackers. There is a new programming language ( created by Jean Yang Assistant Professor in the Computer Science Department at Carnegie Mellon University) with privacy baked in called Jeeves. With Jeeves, developers don’t necessarily have to scrub personal information from their features, because Yang’s code essentially does it automatically. Learn more..
