What makes you sneeze? Sneezing is the most common problem among all humans ,but ever wondered what makes you sneeze? So basically sneeze is associated with irritation. A sneeze is the response of body towards irritation caused due to many factors . So we actually need to know why do we sneeze and what is the slimy , muddy material flowing out through your nose? Sneeze gives us that Zerk to throw out the particle that is responsible for the irritation in trachea. But when under a attack of cold flu, our body goes through a period where there is inflammation in trachea , and the walls touch each other and thus it feels that something trying to enter our body and thus trigger the sneeze algorithm of our body and thus we encounter the same periodic jerk many times in a day due to flu. So what's that mud?? The mucus that flows out through the nose is actually the fluid which is released by body to wash out the particle that is not removed even through jer...

Question Why don't electrons stick to protons if there’s electrons whizzing around the outside of an atom and the protons are the positive bit in the middle? Why don't the two just collapse in on each other? Answer Naked Scientist Dave Ansell got stuck into this question... Okay, in a very simple sense, they do stick to protons as much as they can. They're attracted to protons and so they form atoms. An atom is essentially electrons stuck to protons. What you really are asking though is why don't they get any closer than they do? It's all basically to do with the fact that electrons - in fact, everything - has wave properties. And the electron's wavelengths are about a similar sort of size as an atom, and that's the reason why atoms are that sort of size over the order of the wavelength in electron. And so you can't really compress a wave any smaller than one or few wavelengths. So the electron can't get any smaller than that without actually...

Quasar With the exception of the short-lived, powerful explosions responsible for  supernovae  and  gamma-ray bursts ,  quasars  (or  QSO s) are the brightest objects in the  Universe . They are thought to be powered by  supermassive black holes  (black holes with a  mass  of more than one billion  solar masses ) which lie at the center of massive  galaxies . However, the black holes themselves do not emit visible or radio  light  (i.e. they are “black”) – the light we see from quasars comes from a disk of gas and  stars  called an accretion disk, which surrounds the  black hole . Intense heat and light is emitted from this accretion disk, caused by friction produced from the material swirling around, and eventually into, the black hole. Quasars are typically more than 100 times brighter than the galaxies which host them! Quasars also emit  jets  from their central regions, w...

YOUR PHONE HAS AN FM CHIP. SO WHY CAN'T YOU LISTEN TO THE RADIO? EVERYONE CARRIES THE  Internet in their pocket, yet radio and television remain the primary way people get information in an emergency. So when a disaster knocks out power and takes down cell service—along with those government emergency alerts—you're going to need a radio to know what's going on. A radio? Who owns a radio anymore? You do. Every smart phone in the world has an FM tuner built in. But here in the US, just one-third of them actually works, even though the Federal Emergency Management Agency says  radio can save lives in an emergency . "We know that if Internet networks or cell phone networks go down, FM still works so long as you have a battery to turn the device on," says agency spokesman Rafael Lemaitre. Broadcasters and public safety officials have long urged handset manufacturers and wireless carriers to universally activate the FM chip, and recently  brought the campa...

THE ENOUGH ALREADY !!!! Sick of hearing about Kim Kardashian, Star Wars, or Donald Trump?  The “Enough Already” mutes your TV  when it detects any word or phrase by monitoring the closed captioning. It’ll unmute after 30 seconds as long as the word or phrase isn’t mentioned again. You can program it to block any phrase you want, making TV watching time much more enjoyable.

Quasar outflows may create molecules, as well as destroying them!!! Some types of molecules could form in powerful quasar winds that would ordinarily blast molecules to bits, according to astrophysicists in the US. Their findings, based on computer simulations of the outflows, show that feedback in active galaxies is more complex than had been thought. Quasars are powered by spiralling discs of gas around a supermassive black hole. The gas in the disc is at billions of degrees and drives powerful winds of radiation that move out into the host galaxy at hundreds of kilometres per second, sweeping up molecular gas that could otherwise be used for star formation. Under normal circumstances, this molecular gas should be blasted into its atomic constituents by the outflow radiation. However, observations of quasars have revealed unexpected molecular gas, including carbon monoxide, hydroxyl and warm molecular hydrogen, in the outflows. Now  Alexander Richings  and  C...

Hey there I am providing you latest news from GOOGLE Research... You may go to official page using this  link . Using Evolutionary AutoML to Discover Neural Network Architectures The brain has evolved over a long time, from very simple worm brains  500 million years ago  to a diversity of modern structures today. The human brain, for example, can accomplish a wide variety of activities, many of them effortlessly — telling whether a visual scene contains animals or buildings feels trivial to us, for example. To perform activities like these,  artificial neural networks require careful design by experts over years of difficult research, and typically address one specific task, such as to  find what's in a photograph , to  call a genetic variant , or to  help diagnose a disease . Ideally, one would want to have an automated method to generate the right architecture for any given task. One approach to generate these architectures is through the u...

S cientists have observed a new class of quantum matter at the very smallest scales in one of the coldest environments ever made. This discovery could pave the way for new technologies including innovations in superconductivity and other cutting-edge fields. The researchers examined the behavior of matter on the atomic and subatomic scales – known as “quantum matter” – where a large number of particles interact with each other. This latest discovery reveals a new state of quantum matter called a “Rydberg polaron,” a relatively giant particle containing many atoms that behaves in some ways like a single massive particle. The experiment, initiated by the theoretical work at the Institute for Theoretical Atomic Molecular and Optical Physics (ITAMP) at the Harvard-Smithsonian Center for Astrophysics ( CfA ) and Harvard Physics, was performed in the laboratory of Thomas Killian at Rice University, where the electrons were given so much energy, on the verge of being pulled away from ...

CAN YOU BECOME IMMORTAL? Could someone transfer their consciousness to another body in order to live forever? That's the basis behind new film Selfless, but just how scientifically plausible is it? As the latest episode of AsapSCIENCE explains, we're actually closer than you might think.

What are Pheromones? Pheromones are most commonly thought of as scents that animals give off that will lure a potential mate to them, or scare a potential threat away. Humans also seem to produce these scents naturally. The detection of pheromones, however, is where the problem lies. Scientists have had difficulty finding an area of the brain that detects the pheromones secreted by others. This may be the explanation for why human pheromones are believed to not exist or cause a reaction for humans. A study from the Huddinge University Hospital in Sweden sheds some light on the truth of this conundrum. In the experiment, Ivanka Savic found that smelling synthetic versions of either testosterone or estrogen led to an increase in blood flow to the hypothalamus. The men showed an increase when smelling estrogen and women when smelling testosterone, but neither had a reaction when smelling the scent of the same gender. The hypothalamus is the region of the brain in rodents and other a...

Cholesterol and Heart Disease Cholesterol is probably the best-known steroid because of the widely publicized correlation between cholesterol levels in the blood and heart disease. Cholesterol is synthesized in the liver and is present in almost all body tissues. It is also found in many foods, but we do not require cholesterol in our diet because the body can synthesize all we need. A diet high in cholesterol can lead to high levels of cholesterol in the bloodstream, and the excess can accumulate on the walls of arteries, restricting the flow of blood. This disease of the circulatory system is known as atherosclerosis and is a primary cause of heart disease. Cholesterol travels through the bloodstream packaged in particles that are classified according to their density. Low-density lipoprotein (LDL) particles transport cholesterol from the liver to other tissues. Receptors on the surfaces of cells bind LDL particles, allowing them to be brought into the cell so it can use...

Drugs Bind to Their Receptors Many drugs exert their physiological effects by binding to specific sites, called receptors , on the surface of certain cells  . A drug binds to a receptor using the same kinds of bonding interactions—van der Waals interactions, dipole–dipole interactions, hydrogen bonding—that molecules use to bind to each other. The most important factor in the interaction between a drug and its receptor is a snug fit. Therefore, drugs with similar shapes and properties, which causes them to bind to the same receptor, have similar physiological effects. For example, each of the compounds shown here has a nonpolar, planar, six-membered ring and substituents with similar polarities. They all have anti-inflammatory activity and are known as NSAIDs (non-steroidal anti-inflammatory agents). Salicylic acid has been used for the relief of fever and arthritic pain since 500 b.c. In 1897, acetylsalicylic acid (known by brand names such as Bayer Aspirin, Bufferin,...

In the future, an AI may diagnose eye problems The computer will see you now. Artificial intelligence algorithms may soon bring the diagnostic know-how of an eye doctor to primary care offices and walk-in clinics, speeding up the detection of health problems and the start of treatment, especially in areas where specialized doctors are scarce. The first such program — trained to spot symptoms of diabetes-related vision loss in eye images — is pending approval by the U.S. Food and Drug Administration. While other already approved AI programs help doctors examine medical images, there’s “not a specialist looking over the shoulder of [this] algorithm,” says Michael Abràmoff, who founded and heads a company that developed the system under FDA review, dubbed IDx-DR. “It makes the clinical decision on its own.” IDx-DR and similar AI programs, which are learning to predict everything from age-related sight loss to heart problems just by looking at eye images, don’t follow preprogramm...

50 years ago, pulsars burst onto the scene The strangest signals reaching Earth The search for neutron stars has intensified because of a relatively small area, low in the northern midnight sky, from which the strangest radio signals yet received on Earth are being detected. If the signals come from a star, the source broadcasting the radio waves is very likely the first neutron star ever detected. —  Science News ,  March 16, 1968 That first known neutron star’s  odd pulsating signature  earned it the name “pulsar.” The finding garnered a Nobel Prize just six years after its 1968 announcement — although one of the pulsar’s discoverers, astrophysicist Jocelyn Bell Burnell, was famously excluded. Since then, astronomers have found thousands of these blinking collapsed stars, which have confirmed  Einstein’s theory of gravity  and have been proposed as a kind of  GPS for spacecraft  

Some meteorites contain superconducting bits In the search for new superconductors, scientists are leaving no stone — and no meteorite — unturned. A team of physicists has now found the unusual materials, famous for their ability to conduct electricity without resistance, within two space rocks. The discovery implies that small amounts of superconducting materials might be relatively common in meteorites, James Wampler of the University of California, San Diego, said March 6 at a meeting of the American Physical Society. While the superconducting materials found weren’t new to science, additional interplanetary interlopers might harbor new, more technologically appealing varieties of superconductors, the researchers suggest. Superconductors could potentially beget new, energy-saving technologies, but they have one fatal flaw: They require very cold temperatures to function, making them impractical for most uses. So scientists are  on the hunt for new types of supercond...
