Schistosoma mansoni might not as famous as other nasty parasitic worms like flatworms or roundworms, but outside the U.S. this pesky bugger infests more than 200 million people. Symptoms range from rash to organ damage to paralysis. For years, patients have had to rely on drugs that ward off the infection, but for remote or communities in the developing world this may be out of the question. There's a widely available remedy found almost anywhere in the world though, according to Egyptian researchers. And it's so cheap that it literally grows in the ground: garlic.
A new study looking into how Mexico's soda tax is impacting consumer habits one year after implementation. The results show a decrease in sugar-sweetened beverage consumption accompanied by an increase in sales of untaxed drinks throughout the country.
A new study, performed at Howard University Medical Center found that practicing the transcendental meditation technique seems to stimulate the production of telomerase, an enzyme associated with reduced blood pressure and heart disease. This correlates well with earlier research which found that meditation techniques reduce rates of high blood pressure, heart attack, and stroke, as well as slowing of biological aging.
Throughout our hunter-forager days, humans have developed a subconscious urge to over-eat and became less and less psychologically equipped to avoid obesity, especially during the winter months, a University of Exeter study recently found.
One of the most exciting gadgets we've seen at CES this year comes from a French startup called DietSensor, which collaborated with an Israeli company called Consumer Physics. Their latest product called SCiO is a pocket-sized device that uses near-infrared spectroscopy to tell you how many carbs or calories are found inside your food.
Even though they can't remember a word in mandarin, children from China adopted in France bear the same brain activity response as bilinguals. Essentially, their brains use the same patterns and neural areas as bilinguals even though by all accounts they must think they're monolingual. The implies that the impact of early developmental experiences on later neural outcomes is much more significant than some might think.
These aren't Christmas lights, but the actual neural activity of Caenorhabditis Elegans, a parasitic nematode. The brain imaging was done by researchers at Princeton University, and no worm had to be cut open. Instead, the researchers used a special protein which fluoresces in response to calcium.
Scientists find the specific brain pathway used by ketamine to relieve depression. Now, it's possible to design a new drug like ketamine, sans "K hole".
A new study shows a part of the problem that fuels America's prescription opioid epidemic -- the worst drug abuse episode in the country's history.
Joy Milne's husband was diagnosed with Parkinson's when he was 45, but she felt something was off a few months earlier.
Thousands of babies are being born with brain damage due to a mosquito-borne virus.
Scientists want to grow potatoes on Mars to study crop resilience in the face of climate change. Brilliant or stupid?
The fatty acids in fish oil have been proved to help with a wide range of conditions, with WebMD detailing benefits ranging from improving the health of the heart and circulatory system all the way to fighting dyslexia, kidney disease and improving your child's IQ. Now, scientists from the Kyoto University found that feeding fish oils to lab mice made them gain considerably less weight than their fish-less counterparts.
The Australian government wants to eliminate hepatitis C within one generation - a 'miracle drug' with a price tag of $100,000 will be provided at a cost of only $37.70
In a collaborative effort by the Oregon Healthy and Science University and the University of Pittsburgh researchers have been able to identify the genes whose role is to trigger the onset of puberty, and manipulate them to delay puberty in female rats. They hope that the discovery will help determine exactly why causes early-onset puberty in females.
For more than 200,000 years humans and face mites trace a common history. There’s no human that doesn’t feed these tiny arachnids with some of our delicious face oils, which might startle some. Fret not since these are mostly harmless (though some people are more sensitive to the mites and get rosacea and blepharitis). What’s startling […]
Researchers at the Washington University School of Medicine in St. Louis, looking into the effects depression has on the brain have found proof linking the disorder with abnormal brain development in preschoolers. Their study, published in the journal JAMA Psychiatry, shows how gray matter is thinner and lower in volume in the cortex, an area of the brain that plays a key role in processing emotions.
Northwestern University neuroscientists have developed a method that allows them to pinpoint communicating neurons in a living fly's brain -- effectively paving the way for mind-reading. Their mapping of specific neural connection patterns could provide insight into the computational processes that underlie the workings of the human brain.
Scientists from the University of Ferrara, Italy collaborating with the Beijing Genomics Institute have isolated a gene that, when mutated, causes muscle tissue to become significantly weakened and damaged. Their findings, published in The Journal of Clinical Investigation, show how the gene, dubbed Popeye domain containing-1, has a role in ‘gluing’ muscles cells together.
Obesity rates have increased virtually everywhere in the world, especially in the developed world. Some 160 million Americans are obese or overweight. Over 70 percent of all men and 60 percent of all women from the US are overweight, and it seems like the next generation will have similar problems: nearly 30% of boys and girls under age 20 are either obese or overweight, up from 19% in 1980. When talking strictly about obesity, one-third of American men (32%) and women (34%) were obese in 2013 compared with about 4% of Chinese and Indian adults. Being obese puts you at risk of developing a myriad of conditions from heart disease and stroke, to diabetes, to some cancers, to osteoarthritis. Yet, for all the hazards that being overweight causes most people would rather lose weight to appear more attractive, than be more healthy. The two are interlinked, as we shall see. But that's better than not having any reason at all to lose weight, and now a new study quantified just how much weight men and women need to lose for this to show and make them look more attractive. Some might find the findings useful.
In 2001 a foot-and-mouth disease outbreak in the United Kingdom was traced back to a farmer that illegally fed uncooked waste to his pigs. It left the country's agricultural industry in tatters -- over 10 million sheep and cattle were killed in an effort to contain the disease. Later that year EU legislators banned the use of human food waste (or swill) as pig feed, a decision that is now coming under a lot of fire from disgruntled livestock farmers and the scientific community.
The craziest thing you'll see all day -- predicting what you look like from DNA.
The Internet is a wonderful and wonderfully powerful place. Just think about it, you have access to almost all of human knowledge with just a few key strokes. But having this much information at your disposal seems to actually make us rely less on what we already know.
There is a long-lasting debate dividing the cancer researchers community over the point at which a skin lesion is considered a melanoma. A University of California-San Francisco team led by Hunter Shain might have found the answers to settle the debate once and for all; they have found a way to tell whether a lesion is harmless or growing into a melanoma.
Talks are in full force in Paris at the COP21 climate change conference, but meanwhile in China, Beijing is going through one of its hardest smog events ever. The mayor of Beijing announced on Monday its first red alert for pollution, showing that Chinese smog is still a huge problem.
What generates the different takes on the same problem between men and women? It's not the brain -- we know that for all intents and purposes, brains can't be distinguished by sex (but they do form connections differently). Cultural conditioning, upbringing and other factors certainly play a part in this, and that can't be quantified. But Norwegian University of Science and Technology (NTNU) team was interested in the effect of something we can quantify -- sexual hormones.
A few words on how a well stocked library can drastically improve academic performance later in life for your children.
Men are from Mars, Women are from Venus, or so the old adage goes. But it's wrong.
The island nation has recently announced that it will resume whaling operations in the Antarctic Ocean with the purpose of collecting "scientific data." The decision was met with outrage and heavy criticism by other countries and conservation groups.
A massive, 200 million yuan (over $31 million) commercial animal cloning facility will be built in the Tianjin Economic-Technological Development Area with the sole purpose of cloning China's cattle.
It sounds like a plot from Frankenstein, but apparently there's no limit to how versatile flatworms can be. Previously, researchers at Tufts University determined that the small, yellow worm can retain its memories after it head was severed. As a reminder, flatworms can regrew new heads following decapitation. Now, the same team yet again guillotined some flatworms and interrupted gap junctions, which are protein channels that enable cells to communicate with each other by passing electrical signals back and forth - just to see what would happen. Yes, the flatworm grew a new head, but it was that of another flatworm species. They eventually induced the same flatworm species to grow the heads and brains of multiple other, closely related species. There's a lot of biology and behaviour encoded in genes, but these findings show that tweaking physiological mechanisms in a live body can actually cause new anatomical developments. We might have uncovered a new form of epigenetics.
In a new study published in Nature, researchers have demonstrated a technique that allows the mapping of organs at microscopic scales.
Today, the world seems split into two different parts: some people devouring dramatically large pieces of turkey, and the other ones that simply don’t care about Thanksgiving. But no matter what category you fall into, it’s a good time of the year to enjoy some good food. With this in mind, I thought I’d share […]
Also known as the water bear, the tardigrade has a lot to be proud of -- this tiny organism is nigh-indestructible, known to have survived in extreme temperatures ( -272C to +151C / -457.6F to 303.8F) and to be the only animal that can brave the vacuum of space unprotected and live to tell the tale.
A few days ago, the FDA approved the genetic engineering of modified Atlantic salmon variety. This is the first food animal that was genetically modified that the FDA approved for human consumption and farming; the gene alteration would make it grow much faster. Public reactions have been mixed, as expected. This could be a very good move, greatly reducing the stress on wild populations, but people are always reluctant when it comes to GMOs - especially animals.
After five years long of pondering, the FDA finally gave the green light for a genetically modified Atlantic salmon variety. This is the first food animal that was genetically modified that the FDA approved for human consumption and farming. The salmon has genes from another salmon species, as well as an eel-like fish, which allows it to grow to market size in half the time it would usually take. This means it saves twice as much time and resources as conventional salmon, with no nutritional or health drawbacks, the FDA says.
With robots taking up all the factory jobs and CEO's outsourcing each and any position they can to China, it's harder and harder for the common bloke to find a job these days. And it's only about to get worse as pigeons are now poised to take over the health industry positions for the price of bread crumbs.
A study of 986 Bolivian women found that on average, a lifetime infection with a type of roundworm named Ascarius lumbricoides led to an extra two children in the family. Their paper, published in the journal Science, suggests that the worm is altering the host's immune system, making it easier to become pregnant -- in effect, the parasite increases female fertility. The researchers hope this discovery will lead to "novel fertility enhancing drugs."
A University of Nevada team, led by anthropologist Peter Gray, tested several hypotheses about pets and contemporary courtship or dating rituals. Their study will appear in a forthcoming issue of the journal Anthrozoös.
We all know that men like to impress the fairer members of our species, and this permeates into almost everything we do: we want to drive the shiniest car on the block, crack the funniest jokes 24/7 and write for ZMEScience so we can impress the ladies at parties. In essence, no matter how unlikely it is to actually impress, if a man has a choice between doing something and doing that something over the top so he can show off to women, you can bet your right arm he's gonna do the latter.
About 20 million people in the United States suffer from temporary or permanent voice impairment. Life can sound like a nightmare, even though we don't hear our own voice - but we do feel the attention. Then, those are those rare cases which basically render people mute. While there are various medical interventions that can improve one's voice, it's still far from the real deal. What these people need is not a patch here and there, but a whole new set of vocal cords, and a group of researchers has set out to grow it in the lab. Starting from a couple of human cells, they've grown a critical tissue involved in vocalizing. It's basically indistinguishable from the real deal (it's still biological tissue after all) and biocompatible.
It seems like evolution has fostered us humans all along for us to become the dominant species on planet Earth. We owe so many gifts to the tender processes that began millions of years ago and shaped us the way we are today. Gripping dexterous hands, remarkable social behavior and lets not forget about those big brains. It's not enough to have a big brain, though. What makes us humans particularly successful is our ability to adapt constantly to our environment. Humans fair well in luxurious plains, but they seem to survive in the desert as well. Then look at the times we're living in. Technology, networking, all our cultural heritage. It takes a lot to adapt to such changing times, and no other species seems to be this good at it. While we owe a great deal to genetics, it's brain plasticity - an inherent ability to mold our cerebral connections to fit our environment - that took us the extra mile.
Behind all the glitz and glamour, there's little substance to cosmetic products.
A paper published recently in Nature Communications details how a team lead by Dr. Ben Wilson and Professor Chris Petkov used a brain imaging technique to identify the neuronal evolutionary origins of language. Their findings help us understand how we learn to speak, and could allow new treatments for those who lose this ability from aphasia after a stroke or dementia.
Cardiff University public health experts have discovered a powerful link between a pupil's breakfast quality and their performance at school. The study – the largest to date looking at how nutrition influences school performance -- recorded the breakfast habits of 5000 pupils aged 9 through 11, and their results in the Key Stage 2 Teacher Assessments 6-18 months later.
The FDA, Department of Justice and other government agencies, today presented the results of a yearlong sweep of dietary supplements which are thought to contain unsafe compounds. Following a slew of illnesses and law suits as a results of dietary supplement intake, the combined government effort vowed to crack down on the industry - at least the part that mislabels its products and poses a significant hazard to the population. You'd think drugs - what a lot of supplements contain - would be regulated by the FDA, but dietary supplements are entirely unregulated. This has allowed a $40 billion industry of "snake oil" products to flourish. Not anymore, everyone hopes.
Researchers may have found a much needed weapon against HIV in an unexpected place: alcoholism medication.
Scientists have genetically engineered algae to kill up to 90% of cancer cells in the lab, while leaving the healthy ones unharmed.
A recent study from Iowa State University shows how a gene, found in a single plant species so far, can increase protein content when grafted into the DNA of staple crops. Their findings could help improve a huge variety of crops and improve nutrition in developing parts of the world, where available sources of protein are sometimes limited.
Today is World Prematurity Day - a global effort to raise awareness about the deaths and disabilities due to premature births. Each year around the world, 15 million babies are delivered ahead of term and 1 million children die before their fifth birthday from related complications. Some who make it past this dangerous threshold might get to live with serious disabilities.
