All-Atom Molecular Dynamics Simulations

by ragothamanyennamalli in Getting to know Structural Bioinformatics

With increasing computational power (aka GPU) that can be accessed these days, it is no wonder that performing all-atom molecular dynamics simulation for a longer time, with duplicates and/or triplicates, has become easier.... Read more »

Distortions of Reality

by The Neurocritic in The Neurocritic





President Trump this week repeated an assertion he made shortly after his election: that millions of ballots cast illegally by undocumented immigrants cost him the popular vote. If true, this would suggest the wholesale corruption of American democracy.

Not to worry: As far as anyone knows, the president’s assertion is akin to saying that millions of unicorns also voted illegally.

The science behind real life zombies

by Dr. Jekyll in Lunatic Laboratories

In the spirit of Halloween we bring you the science fact and fiction behind the undead. Zombies, those brain loving little guys, (and girls) are everywhere. Sure, we are all familiar with the classic zombie, but did you know that we aren't the only zombie lovers out there? It turns out that nature has its own special types of zombies, but this isn't a science fiction movie, this is science fact! Sometimes fact can be scarier than fiction, so let's dive in.

Red meat and organs may pose a significant health hazard

by Dr. Jekyll in Lunatic Laboratories

Neu5Gc, a non-human sialic acid sugar molecule common in red meat that increases the risk of tumor formation in humans, is also prevalent in pig organs, with concentrations increasing as the organs are cooked, a study has found. The research suggests that Neu5Gc may pose a significant health hazard among those who regularly consume organ meats from pigs.

Potentially harmful chemicals widespread in household dust

by Dr. Jekyll in Lunatic Laboratories

Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a new study. A multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust.

Food waste could store solar and wind energy, or there's the obvious...

by Dr. Jekyll in Lunatic Laboratories

Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.

Antimicrobial chemicals found with antibiotic-resistance genes in indoor dust

by Dr. Jekyll in Lunatic Laboratories

Researchers have found links between the levels of antimicrobial chemicals and antibiotic-resistance genes in the dust of an aging building used for athletics and academics. One of the antimicrobials seen in the study is triclosan, a commonly used antibacterial ingredient in many personal care products.

Body heat as a power source

by Dr. Jekyll in Lunatic Laboratories

Electronics integrated into textiles are gaining in popularity: Systems like smartphone displays in a sleeve or sensors to detect physical performance in athletic wear have already been produced. The main problem with these systems tends to be the lack of a comfortable, equally wearable source of power. Chinese scientists are now aiming to obtain the necessary energy from body heat by introducing a flexible, wearable thermocell based on two different gel electrolytes.

Drugs in the water? Don't blame the students

by Dr. Jekyll in Lunatic Laboratories

With nearly sixty percent of American adults now taking prescription medications--from antidepressants to cholesterol treatments--there is growing concern about how many drugs are flowing through wastewater treatment facilities and into rivers and lakes. Research confirms that pharmaceutical pollution can cause damage to fish and other ecological problems--and may pose risks to human health too.

Intestinal flora effects drug response

by Dr. Jekyll in Lunatic Laboratories

Intestinal flora has multiple influences on human health, but researchers have revealed that it is also likely to have an effect on the body's response to drugs. Recent research suggests that changes in the intestinal flora, caused by antibacterial and antibiotic drugs or individual differences between people, may have an effect on a person's response to drugs including side effects. The research focused on the changes in proteins due to the condition of intestinal flora that affect th........ Read more »

Fish May Lose Their Jelly Friends in a Changing Ocean

by Elizabeth Preston in Inkfish



In the open ocean, it's good to have friends. Some young fish like to buddy up with stinging jellies to stay safe from predators. Hiding under the shelter of a jellyfish's bell, they can grow up unharmed (as long as they dodge its tentacles). These fish include some species that humans rely on for food. But in a warming ocean, that buddy system may fall apart.

Many types of fish take advantage of hop-on jelly trolleys. Ivan Nagelkerken, a marine biologist at the University of Adelaide in ... Read more »

The antibiotic arms race is on, while we are rushing to find new antibiotics, bacteria are working on finding ways around them. With that in mind, a new experimental antibiotic developed by a team of scientists successfully treats the deadly MRSA infection and restores the efficacy of a commonly prescribed antibiotic that has become ineffective against MRSA.

Beetle Moms Make Anti-Aphrodisiac to Keep Dads Focused on Parenting

by Elizabeth Preston in Inkfish



"Not tonight, honey," says the female burying beetle, chewing up a mouthful of mouse carcass before spitting it into the mouth of a begging larva.

For the first few days of their babies' lives, burying beetles co-parent. They devote themselves to keeping their squirming larvae alive. That means mating and laying more eggs would be a waste of energy. And to make sure males get that message, females emit a pheromone that turns them off.

"It is quite surprising," says University of Ulm be... Read more »

The Smell of the Cinema: Human Chemical Signals?

by Neuroskeptic in Neuroskeptic_Discover

The air in a cinema contains a chemical cocktail emitted by the audience - and the emotional tone of the movie influences the molecular composition of the cloud.

That's according to a striking set of results from researchers Johnathan Williams and colleagues who took air samples from two 230-seater screens of a cinema in Germany over a period of two weeks.





Here's an example of the chemical trace associated with shows of the movie "The Hunger Games 2: Catching Fire", featuring three... Read more »

The Princess IS the Frog (A Guest Post)

By Hayley TrzinskiImage by Hayley TrzinskiThe Princess and the Frog is a very fun and imaginative children’s story… but not when pesticides are involved. Have you ever wondered how dangerous pesticides can be? Well, pesticides can harm more than just pests and weeds, and in the case of frogs, many pesticides and herbicides are causing problems. Atrazine, a chemical commonly used as an herbicide, can cause reproduction in male African clawed frogs to be impossible. In some cases, atrazine i........ Read more »

Uncovering the genetic elements that drive regeneration

by Dr. Jekyll in Lunatic Laboratories

Lose a hand or a leg? It will grow back… oh wait, it won’t, but why not? Trace our evolution — long before the shedding of gills or the development of opposable thumbs — and you will likely find a common ancestor with the amazing ability to regenerate lost body parts. There is theoretically no reason why we shouldn’t be able to regenerate, not quite like in the movie Deadpool, but come on, would you really complain at that point?

Your brain has an altered response to desirable foods

by Dr. Jekyll in Lunatic Laboratories

Hungry? Well, let’s face it, that pizza looks much better than the salad. Don’t deny it salad lovers, we all know behind closed doors you look at plenty of food porn to satiate your desires. Understanding the motivations that drive us to eat is important when we talk about weight loss and how we attempt to structure diets. Now a new study shows that for overweight individuals, the brain responses differently to desirable foods., but hold that thought, because there is hope.
