Fish, mercury, and pregnancy: Good news for seafood lovers

by Gabriel in Lunatic Laboratories

People freak out when they hear mercury is in something and sometimes for good reasons. In vaccinations for example a very small amount of ethyl-mercury WAS used as a preservative in vaccines, people got scared so now it is not used in most vaccines. Methylmercury* however is found in seafood and larger fish in particular (in much, much higher concentrations than in vaccines mind you). They may sound the same, but the methylmercury in fish is far more toxic. That said, it turns out that fish isn........ Read more »

Polar Bears Leave Messages in Their Footprints

by Elizabeth Preston in Inkfish



If a polar bear tells you to talk to the hand, don't be offended. The animals seem to communicate with each other through scent trails left by their paws. Their tracks tell a story to the other bears roaming their habitat, helping potential mates to find each other—as long as there's habitat left, anyway.

As they crisscross the snowy Arctic, polar bears are usually alone. In other solitary bear species, animals leave messages for each other by rubbing their bodies or urine onto trees or........ Read more »

Creating a better diet pill: The new drug that is making big promises

by Gabriel in Lunatic Laboratories

Losing the weight, some of us never seem to be able to do it. Whether it is poor choice in diet, a medical condition, or just a sedentary lifestyle people everywhere are finding they can’t shed the pounds. Now there is a new drug that promises help in the weight loss department and works like nothing we’ve seen used for weight loss yet. The compound effectively stopped weight gain, lowered cholesterol, controlled blood sugar and minimized inflammation in mice, making it an excellent candidat........ Read more »

Steak raises cancer risk and now we know why

by Gabriel in Lunatic Laboratories

Some of you may remember a recent study showing why red meat is bad for the heart, while now there is a study showing why steak — or in particular red meats — raise the risk of cancer. To be clear, I am still very much a red meat eater and this is no way intended to change anyones opinions on steak consumption, but it is nice to understand the science behind what we put in our mouths....

More On The Mystery of "Quantum Resonance Spectrometry"

by Neuroskeptic in Neuroskeptic_Discover

Back in April, I blogged about a paper published in the Journal of Nervous and Mental Disease (JNMD) claiming that a little-known technique called ‘quantum resonance spectrometry’ (QRS) was able to diagnose mental health problems. I expressed surprise that the paper didn't explain what QRS actually is, how it works, or what it measures.





Now, eight months later, a Letter to the Editor has been published in the JNMD: Methodological Queries Regarding "Exploratory Quantum Resonance Spectr... Read more »

Nanoparticles could deliver drugs to the brain

by Gabriel in Lunatic Laboratories

Science has already shown that when it comes to strokes, the sooner you treat it the better your outcome. Well now, stroke victims could have more time to seek treatment that could reduce harmful effects on the brain, thanks to tiny blobs of gelatin that could deliver the medication to the brain. The best part, this would be done noninvasively.... Read more »

The Chemistry of Christmas

by Melissa Chernick in Science Storiented

What are the sights, the sounds, the smells, and the textures that you associate with Christmas? Perhaps it is Christmas trees with their lovely green shape, color and wonderful pine smell. Maybe it’s the smells of cooking, the savory smells of turkey or the sweet smell of warm cookies. Or what about all of the cozy feelings you get with big sweaters or a roaring fire? Did you know that there is a lot of chemistry that goes into all of the senses we associate with this holiday?I was browsing t........ Read more »

A new type of memory storage on the horizon

by Gabriel in Lunatic Laboratories

For those of us old enough to remember the days of the Apple II, you know that storage has exponentially increased. Even just 10 years ago 20+ gigs of data seemed huge, now my cellphone has 64 gigs. Yet we still need more data storage and we are looking for new ways to get it. Now a way to use weak molecular bonding interactions to create well-ordered and stable metal–organic monolayers with optoelectronic properties has been found. The development could form the basis for the scalable fabrica........ Read more »

What makes us fat, OR food vs. physiology

by Gabriel in Lunatic Laboratories

There is a heir of mystery surrounding weight loss and fat in general. Have you ever heard you have all the fat cells you’ll ever have — that’s false by the way. Then there is fad diets like gluten free — proven to do nothing unless you actually have a diagnosed gluten allergy — or adkins, but now researchers believe they’re on track to solve the mystery of weight gain – and it has nothing to do with indulging in holiday eggnog....

Depressed? Laughing gas might help

by Gabriel in Lunatic Laboratories

Nitrous oxide, or laughing gas, has shown early promise as a potential treatment for severe depression in patients whose symptoms don’t respond to standard therapies. In other words, it might actually live up to it’s name and as they say laughter is the best medicine. The pilot study is believed to be the first research in which patients with depression were given laughing gas.... Read more »

Move over solar pannels, introducing spray-on solar cells

by Gabriel in Lunatic Laboratories

Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms. Well that is until now, researchers have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture....

Synthetic biology breakthrough: The world’s first artificial enzymes

by Gabriel in Lunatic Laboratories

Like mad scientists working away in some secret location we have created life… well sort of. It may sound like something out of a Sci fi movie, but scientists have created the world’s first enzymes made from artificial genetic material. Their synthetic enzymes (which are made from molecules that do not occur anywhere in nature) are capable of triggering chemical reactions in the lab and are the building blocks for life....

Our Increased carbon dioxide output causes global warming and now we have proof

by Gabriel in Lunatic Laboratories

Global warming, it’s a bigger deal than some people seem to realize. For years science has pointed to the increased carbon dioxide output as the main reason for man-made global warming. However, there has been no evidence to directly link CO2 output to global warming, well until now. Research has identified, for the first time, how global warming is related to the amount of carbon emitted.... Read more »

Worm Defies Tradition, Stores Gut Bacteria in Gills Instead

by Elizabeth Preston in Inkfish

What—just because they’re called gut microbes, you’ve been keeping them in your colon? How unoriginal. This is Bankia setacea, also called the Northwest or feathery shipworm. Humans usually pay attention to shipworms only when they perform their namesake activity: burrowing face-first into our boats or docks and eating their way through.
