Foldit is definitely a niche game. The sole gameplay mechanic is attempting to fold complex proteins into smaller and more efficient shapes following the rules of molecular physics and biology. Points are awarded based on how small one can make the protein. Online leaderboards track players' relative progress and allows them to view and manipulate other players' completed designs. It's original, certainly, but no developer is going to ship a million units of a game about molecular-level prote...
Michelle Phan presents this tutorial on how to take a tomato and turn it into an invigorating scrub.
First off, don't be frustrated. YOU CAN DO IT! Contrary to the message in the image above, it's NOT over. It's just beginning. And when it comes to solving the New York Times crossword puzzle, the old cliche does apply: practice makes perfect.
In this video, we learn how to easily balance a chemical equation. In a balanced equation, there should be the same number of atoms on both sides of it. There are no rules that explain how you get a balanced reaction from expression. First, start on the molecule or compound that is the most atomically complex. After you look at this, you can learn how to make the rest of the equation equal to each side. This is a complex process that you must walk through to figure out, but it will result in ...
This is a video tutorial in the Education category where you are going to learn how to describe chemical formulas. A chemical formula represents the actual number of atoms of each element within a molecule. Different visual representations of molecules include the ball and stick three dimensional model, a line drawing that represents the structure in two dimensional terms, and a shorthand used by organic chemists. If a molecule has 4 green atoms and 2 orange atoms, the ratio of green to orang...
An in-depth explanation of the structure of the hemoglobin molecule, the process by which it binds with the oxygen in the lungs, how it dumps the same oxygen molecule at the appropriate location in the body and how carbon-dioxide gets attached to the hemoglobin molecule are the topics which the narrator in this video explains with diagrams and a few equations.

Two college students; Kevin Martin and Joey Smokey introduce the concept of Molar Mass. They start of by explaining what molar mass is, which is the relationship of a mole and a gram, it totals up the weight(in g)of a molecule. An example: say you have this compound, Sodium phosphate (Na3PO4). You know you have three sodium atoms, one phosphorus atom, and four oxygen atoms. You basically find the weight of each atom, if you have three sodium atoms, you multiply it's atomic mass by 3 (the numb...
Inside the container we have some water molecules and inside those water molecules we have some sugar molecules. We have more water molecules so in this case the thing which is more of called SOLVENT and the thing which is lesser is called SOLUTE. We can say sugar molecule dissolves in the water. The combination of Solvent and Solute is called the SOLUTION. Diffusion is spreading the molecules from high concentration to low concentration. If we take two containers of water which are joined fr...
Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
It feels like someone reached into your chest and squeezed. Your head throbs in unison with your heartbeat. Clammy dread coats your body in sweat. Whether you call 911 or someone does it for you, the ER is your next stop.
Instruction on how to make a spiked truncated icosahedron AKA "Hairy Buckyball" (don't think it's an official stellation of the truncated icosahedron) or Buckminster fullerene molecule (every spike is a C-atom).
Garlic is magical. It fends off vampires (or so I hear), helps lower blood pressure, reduces the production of cholesterol in the body... oh, and it's also freaking delicious, of course. Garlic is a culinary staple in countries all over the world. That lovable stink and sharp bite of flavor are essential to many dishes we know and love today, from spaghetti to sesame chicken.
It's a small but very real frustration: you want a chilled drink, but you open the freezer only to see nothing but empty ice trays. Fortunately, there's a simple way to make ice cubes quickly—use hot water. Yup, you read that correctly. Hot water freezes more rapidly than cold.
While the concepts of molecule interaction, zero force and energy states might be a little beyond an elementary school science fair's scope, the basic idea of water's capabilities and naturally prepared access to animals and insects that rely on it as a habitat is certainly worth the time. Learn how to duplicate this natural phenomenon in this free video clip series with our expert Scott Thompson as he demonstrates the occurrence of water skin or skin tension, and shows you and your children ...
Sodium (chemical symbol Na) is an interesting element. It reacts in contact with both oxygen and water, and several sodium salts are used to produce a yellow color in fireworks.
In this video, I'll be showing you how classic black snakes work and how to make them at home. There are actually two methods covered in the video — one that uses fire and one that does not. So just choose the one that fits best for your situation.
Shanghai-based Realmax is introducing the crowds at CES to the Realmax Qian, an augmented reality headset capable of a field of view (FoV) that topples anything available on the market today.
New research reveals how E. coli bacteria construct elaborate and effective tunnels to pump unwanted molecules like antibiotics and other toxins out of cells. The discovery could help us better understand how antibiotic resistance occurs and give us a leg-up to beat them at their own game.
Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity producers.
There's something primal about the smell of smoking food. Somewhere deep in the recesses of our souls, we remember a time when humans only ate by the fire. Or perhaps that's just something I tell myself. Either way, it's hard to smell smoke and food and not feel like you should be eating. And, as chef Edi Frauneder said in a recent Saveur article, "Grilling is convivial. There's something about this act of coming together over an open flame that just says vacation."
For about a million Americans each year, a joint replacement brings relief from pain and restored mobility. But, 5–10% of those people have to endure another surgery within seven years, and most of those are due to an infection in their new joint. If doctors could treat infections more effectively, patients could avoid a second surgery, more pain, and another rehabilitation.
Bone loss and belly fat may no longer be certain fates of menopause, thanks to new research from an international team of scientists.
Significant strides have been in the race to find antibiotics to treat superbug infections — those caused by bacteria resistant to the antibiotics used to treat them. Now, an international team of scientists has discovered a new antibiotic produced by a microbe found in Italian soil.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
We fight cancer in a variety of ways, but no matter whether drugs, biologics, or our immune cells are part of the battle, they can do a better job fighting back cancer if we can help them find the tumors.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
An advance in the race to stop birth defects caused by Zika-infected mothers has been made by a team of researchers from Rensselaer Polytechnic Institute in Troy, New York. They have identified the process Zika uses to gain entry into the placenta, and published their findings in the journal Biochemistry.
Scientists are constantly on the search for new organisms, species, and other types of life. A special group of these researchers, calling themselves "bioprospectors," dive deep into mines to find unique lifeforms with special properties not found anywhere else.
A gold-medal winning entry into the iGEM synthetic biology competition could change the way we look at Esherichia coli, the bacteria better known as E. coli.
If you could save the world by eating a burger, would you? Two companies, Beyond Meat and Impossible Foods, are on a mission to redefine veggie burgers and eliminate all of the downsides of animal farming on our planet. With over five years of research and product testing, they've finally figured out how to make a plant-based burger look, feel, and taste just like real meat.
Soup can be one of the most finicky dishes to make. While seemingly innocuous at first, the texture of this meal can change in an instant. For example, adding too many vegetables can result in soup that's too watery, such as tomatoes, which contain a lot of liquid.
I own two aprons—a cute one for company, and another for the hard-core cooking duties, like cutting up chicken and making stock. The sad truth is that I almost never remember to wear either of them. So, much of my clothing ends up spattered with grease, liquid, and bits of fruit and vegetable. While stain-removing sprays, sticks, and pens are all effective to a certain extent, they have two drawbacks—they're expensive and sometimes I need to use them in large quantity, like when a piece of eg...
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
