Our Solar System started off as a swirling cloud of dust and gas which eventually collapsed into a spinning disc with the Sun at its centre. They are extremely fast swimmers and have been recorded at speeds of up to 54kph! Gut bacteria is also very important for maintaining immunity. A person’s sneeze can travel at speeds of about 100 miles per … Everyday science. A recap of Live Science's best. And today science has become an important subject. However, this list is much too short; keep it growing by adding your own science facts in the comments section. For this reason, large structures such as bridges are built with expansion joints which allow them some leeway to expand and contract without causing any damage. Communities are built on science. Why don’t more people appreciate science? Now that you know what we are talking about, it is time for some fun, good-to-know science facts! It’s funny how … There are certain metals – including potassium, sodium, lithium, rubidium and caesium – that are so reactive that they oxidise (or tarnish) instantly when exposed to air. Books. But beyond these common states of matter, scientists have discovered a myriad of exotic states of matter that occur under special conditions. Moreover, if you’d laid down end to end each water molecule from a teaspoon down end to end, you’d end up with a length of 50 billion km — 10 times the width of our solar system. A human organ that no-one knew about has been hiding in plain sight all this time. They thus occupy a huge amount of space. Acceleration is the change in speed of an object over time, often measured in ‘g’s, with one g equal to the acceleration caused by. Electrons can only exist where the crests and troughs of these waves add up correctly. The plates’ pace is comparable to the speed at which our fingernails grow. Hypotheses were clearly defined prior to analyses. The bears keep warm due to a thick layer of blubber under the skin. Daily
Unlike any other marine plant, they surround themselves with minuscule plates of calcite (coccoliths). When did we first start forecasting the weather? Glass is actually a liquid, it just flows very, very slowly. With this in mind, here are a couple amazing scientific facts that I hope will inspire you to learn something new every day — they’ve certainly done so for me. A typical hurricane produces the energy equivalent of 8,000 one megaton bombs. A teaspoon of water (about 5 mL) contains 2×1023 water molecules, but each water molecule is comprised of 3 atoms: two hydrogen atoms and one of oxygen. Randomization was performed for the treatment of interest. Updated daily with science research articles in all the life sciences. When a substance is heated up, its particles move more and it takes up a larger volume – this is known as thermal expansion. So, if you multiply the amount of blood that the heart can pump by the number of beats in a minute, you actually get about 4.9 liters of blood pumped per minute, which is almost your whole body’s worth of blood. Conversely, a drop in temperature causes it to contract again. “If you set [down] a cup with a liquid circulating around and you come back 10 minutes later, of course, it’s stopped moving,” says John Beamish, an experimental physicist at the University of Alberta in Edmonton. Variations in temperature and density create currents in this iron, which in turn produce electrical currents. Powered by - Designed with the Hueman theme, Our atmosphere is made up of roughly 78 per cent nitrogen and 21 per cent oxygen, with various other gases present in small amounts. The atoms that make up the world around us seem solid but are in fact over 99.99999 per cent empty space. Over time, rock forms in horizontal layers, leaving older rocks at the bottom and younger rocks near the top. Besides, events like cooking, boiling of water, burning of a candle, curdling of milk, electricity, motorized vehicles, cell phones etc. Welcome to our second year of the School's Out: Top 10 Summer Learning series! The reason is that Betelgeuse is a supergiant star — the largest type of star in the Universe. Carbon dating estimates a fossil’s age more precisely, based on the rate of decay of radioactive elements such as carbon-14. When the octopus swims, the organ heart stops beating, which explains why these creatures prefer to crawl rather than swim (it exhausts them). In fact, we couldn’t survive without them. There is enough DNA in an average person's body to stretch from the sun to Pluto and back -- 17 times.
A museum's narwhal tusk disappeared more than 40 years ago. Being neither … An octopus also has nine brains — well, sort of. Because it’s near the end of its lifetime, Betelgeuse is likely to explode into a supernova. The vast majority of. The small “You Are Here” sticker that indicates your position on a map has a name- it’s called an ideo locator. Still think we’re alone? 2. Like the ears of people, the grasshopper sound detector is a thin membrane called a tympanum, or “eardrum”. Batteries. Cool Merch; Live Science is supported by its audience. Home. The Great Barrier Reef is an interlinked system of about 3,000 reefs and 900 coral islands divided by narrow passages, located just beneath the surface of the Coral Sea. It seems like everyone wants to be happy and have a great life; nobody wants to get bored, living a lousy and mediocre life.. Win a smartwatch and wireless headphones worth £230! A photon travels, on average, a particular distance before being briefly absorbed and released by an atom, which scatters it in a new random direction. Essentially, the atoms behave like one super atom, acting in unison. So let’s understand our world better by going through these interesting facts about science. A neutron star is the remnants of a massive star that has run out of fuel. Your stomach digests food thanks to highly corrosive hydrochloric acid with a pH of 2 to 3. If you’re a little bit more versed in physics, you also know about the fourth fundamental state of matter called plasma — a hot ionized gas, with prime examples including lightning or neon signs. A wild orca pod can cover over 160 kilometers a day, foraging, and socializing. Over the coming hundreds of millions of … According to a UN report from 2015, 2.5 billion of the world's 7 billion people lack access to a toilet, particularly… The grasshopper tympanum is adapted to vibrate in response to signals that are important to the grasshopper. A jumping flea reaches dizzying heights of about eight centimetres (three inches) in a millisecond. Personally, I believe it has something to do with science communication and the way we teach science in our schools. Thermal cameras detect the heat lost by a subject as infrared, but polar bears are experts at conserving heat. Don’t worry, though: most of these bacteria are helpful. For example, bacteria produce chemicals that help us harness energy and nutrients from our food. A healthy heart also beats around 70 times a minute. They're all here, and you can rely on us to put the 'fun' in fundamental science for you. Betelgeuse lies some 430 light-years from Earth, yet it’s already one of the brightest stars in Earth’s sky. generally make us realize the presence of science in everyday life. There are many definitions one can find over the web, but the basic one follows as “the study of the world around us.” Studying and understand the world is all science about.

This extra flexibility helps them pass through the birth canal and also allows for rapid growth. There’s one ‘main’ brain where all the analysis and decision making takes place and eight ancillary brains — one at the base of each arm — that function as preprocessors for all the information obtained by that arm. The human... 2. The alkali metals have only one electron on their outer shell, making them ultra-keen to pass on this unwanted passenger to another element via bonding. Coral reefs consist of huge numbers of individual coral polyps (soft-bodied, invertebrate animals) that are linked together by tissue. Over the coming hundreds of millions of years, the Sun will continue to get progressively brighter and hotter. How Do Glow Sticks Glow? It’s actually true, Mr. Tiny single-celled algae called coccolithophores have lived in Earth’s oceans for 200 million years. Not every student will grow up and study physics on a deeper level, but everyone uses basic physics concepts to navigate everyday life. When helium is just a few degrees below its boiling point of –452°F (–269°C), it can suddenly do things that other fluids can’t, like dribble through molecule-thin cracks, climb up and over the sides of a dish, and remain motionless when its container is spun.
