The authors of the study suggest that the microbial mayhem explains why the bears occasionally poop out their intestinal mucosal linings amid that seasonal shift.If the hypotheses hold up in further studies, the findings may help explain why pandas are notoriously bad breeders—it s likely hard to get in the mood if you re battling stomach cramps, bloating, and mucus poops.Currently, there are only a couple thousand giant pandas in the wild.But during the fall, the silica levels in the foliage drop and the bears ditch the stalks and go for the leaves.The mucus-filled dropping, on the other hand, had huge spikes in microbial levels, particularly of bacteria that cling to mucosal linings and some linked to inflammatory bowel disease.While the study is just on two animals and doesn t point to any clear solutions, the authors are hopeful that it s a starting point to study better care for the animals, such as dietary supplements or offering different food sources.

Joanna ServaesAfter several hints that gut microbes may be key players in the obesity epidemic, a new study provides a mechanistic explanation of how the intestinal inhabitants directly induce hunger, insulin resistance, and ultimately obesity in rodents.After mice and rats were fed a high-fat diet, their gut microbes produced more acetate, a short-chain fatty acid made during bacterial fermentation.That acetate spread throughout the rodents bodies and into their brains where it activated the parasympathetic nervous system.By activating the parasympathetic nervous system, the microbe-made acetate spurred the rodents to produce more insulin, a hormone made by pancreatic β-cells that promotes calorie storage, as well as ghrelin, a hormone involved in hunger.The result was rodents that ate more developed insulin resistance—a precursor to diabetes—and became obese, the researchers report in Nature.This generates a positive feedback loop, the authors conclude—which makes sense for foraging animals, they add.
And according to a new study, leaving your gut in charge all the time might not be a bad idea—it may actually help dodge neurodevelopmental disorders.If the findings do hold up in more animal studies and human trials, it could mean that treatments as simple and unfussy as probiotic foods could relieve some symptoms of neurodevelopmental disorders, including autism spectrum disorder, the authors conclude.With all of that and other data on the mounting importance of the gut-brain axis, the researchers hypothesized that an out of whack gut microbiome may play a role in the development of disorders such as autism.Researchers examined the mice's microbiomes and found that they had less microbial diversity than control mice born to normal weight moms.Oxytocin is a hormone involved in many things, including social behavior, anxiety, and autism.Still, the study provides a proof of concept that probiotics can treat certain social disorders.
Scientists now agree that zikaviruset can cause microcephaly, that is when the baby is born with abnormally small head. Studies show that zikaviruset can infect cells of the nervous system quite easily and, in some cases, even aggressive. - It seems that the virus can have a number of other effects that go beyond microcephaly, says Tarun Dua, who is working with WHO to coordinate efforts against Zika, to Science. For example, Brazilian researchers reported recently in The Lancet about a two-month-old boy who had microcephaly, but suffering from spasms in the limbs and whose retinas were damaged while the cavity of the brain was significantly larger than normal. Other reports suggest problems with the heart, ears, gastrointestinal tract and genitals. Meanwhile, in July, the WHO gathering 50 researchers and doctors in Recife in Brazil in an attempt to sort out whether and if so, what this zikasyndrom actually consists of.
Scientists have discovered further evidence that Chronic Fatigue Syndrome is not psychological and could actually be caused by bacteria in the gut.Furthermore our detection of a biological abnormality provides further evidence against the ridiculous concept that the disease is psychological in origin.Symptoms of CF mean that normal levels of exertion leads to debilitating fatigue that isn t alleviated by rest.The experiments used 48 people diagnosed with CF and 39 healthy controls and was able to find specific bacterial markers in the gastrointestinal system of those with the disease.SEE ALSOCurrent treatment on the NHS is limited to cognitive behavioural therapy or exercise regimes but Giloteaux believes clinicians should consider changing patient s diets.Maybe clinicians could consider changing diet, use prebiotics as dietary fibre or probiotics to help treat the disease.
Researchers at the Massachusetts Institute of Technology are designing an ingestible robot that could bpatch wounds, deliver medicine or dislodge a foreign object.They call their experiment an "origami robot" because the accordion-shaped gadget gets folded up and frozen into an ice capsule."You swallow the robot, and when it gets to your stomach the ice melts and the robot unfolds," said Daniela Rus, a professor who directs MIT's Computer Science and Artificial Intelligence Laboratory."Then, we can direct it to a very precise location."It's still a long way before the device can be deployed in a human or animal.In the meantime, the researchers have created an artificial stomach made of silicone to test it.
A robotic surgeon bested its human counterpart by stitching up a pig s intestine just a few months ago.Although human supervisors occasionally gave the robot a hand, the medical and robotic breakthrough seemed to herald an era in which human surgeons played a secondary role to machines.But new researcher on robotic surgery for prostate cancer suggests that, despite the oft-perceived benefit having a robot-assisted operation, humans and machines are pretty much equal when it comes to a patient s recovery months after surgery.Robot-assisted prostatectomy allows a surgeon to operate robotic arms remotely from a console.This method has been used for the past 16 years and is now often recommended by practitioners, who suggest it provides better outcomes for patients.The traditional method is an open surgery, in which the patient s prostate is removed through an incision in the lower abdomen.
Our bodies aren t meant to ingest heavy metals, but modern day medicine is aided by implantable devices that serve as stimulators, biosensors, and controlled-release devices.These devices are often packed with batteries that are themselves packed with toxic chemicals, so researchers from Carnegie Mellon University looked for a way to make them easier for our bodies to digest.Battery-operated medical devices have been around for decades and, though many components of the devices are biodegradable, the batteries they carry are not.To that end, CMU and researchers from Bettinger Group developed biologically-derived materials for use in edible electronics.Bettinger and his team had to create an edible battery that could supply the necessary power for the ingestible device s trip down the gastrointestinal tract.So, in the researchers recent work, they designed and fabricated a battery made from materials found in everyday diets.
When virologist Mary Estes first started studying norovirus—the bug best known for causing vomiting and diarrhea on cruise ships—she had a basic problem.So she got more the only way scientists knew how at the time: Take stool samples from a norovirus patient, infect brave volunteers, and wait for them to poop out norovirus particles by the millions.She spent the next two years looking for a better way to grow norovirus.Norovirus is surprisingly finicky: It can grow like crazy in your gut, but it just will not grow in a petri dish.So Estes, now at Baylor, recreated the human gut in a petri dish—growing stem cells that turn into little balls of gut tissue.This is a major breakthrough for a virus that sickens 20 million Americans a year, yet still remains fundamentally mysterious.
By Martinne Geller and Ben HirschlerLONDON Reuters - Switzerland's Nestle , the world's largest food company, wants to tune up your guts.Last weekend, it hosted global experts in Playa del Carmen, Mexico for a three-day workshop on the intestinal microbiome to discuss how trillions of bacteria living in the digestive system can impact everything from obesity to depression.One attendee was Emeran Mayer, a gastroenterologist at the University of California, Los Angeles, whose family ran a German confectionery business, giving him a unique perspective on Nestle's ambitions.He will assume direct oversight of the health science business, which currently operates as a standalone unit.The concept has already given the world faecal transplants that can cure patients with life-threatening C. difficile infections by replenishing their gut flora with bacteria from a healthy person's stool, delivered via a nasal or rectal tube.

In many parts of the world, it s not uncommon to eat other bits of an animal, such as ears, stomach, feet, liver, tail, or intestines.Of course, it helps that they re cheaper and easier to get in other countries, but if you re willing to try something new, don t miss out on these delicious, varied sources of vitamins and protein.You d be hard-pressed to find beef heart or fish head just lying around in your average grocery store.You ll have to widen your search to include butcher shops, farmer s markets, and ethnic supermarkets and restaurants.Some of these options can be spendy, but they don t have to be with these tips:At a butcher shop, ask if they could save you and sell the parts liver, gizzard, heart, feet, head, neck, kidneys, intestines, tail, and so forth they would ve tossed for cheaper.
Lying in a bath in Bristol, UK, is a robotic scavenger, gorging itself on its surroundings.Developed by a Bristol-based collaboration, this robot imitates the life of salps – squishy tube-shaped marine organisms.They digest any tasty treats that pass through their body, giving them just enough energy to wiggle about.By opening its mouth , made from a soft polymer membrane, the robot can suck in a belly full of water and biomatter.The artificial gut – a microbial fuel cell MFC – is filled with greedy microbes that break down the biomass and convert its chemical energy into electrical energy, which powers the robot.Digested waste matter is then expelled out the rear end, just as more water is sucked in the front for the next feed.
A thin layer mimics the structure of the intestinesScientists have designed a new prototype battery that mimics the structure of the human intestines.It's a type of battery called lithium-sulphur, which - in theory - could have five times the energy density of the lithium-ion forms in wide use today.But the prototype developed by a UK-Chinese team overcomes a key hurdle to their commercial development by taking inspiration from the gut.Details appear in the journal Advanced Functional Materials.One of the problems hindering the commercial development of lithium-sulphur-based devices has been the degradation of the batteries caused by the loss of active materials within.
These finger-like protrusions, each about a millimetre long, massively increase the surface area of the intestine, making digestion way more efficient.Now, a team of Chinese and British materials scientists have used exactly the same principle to make batteries way more efficient."It's a tiny thing, this layer, but it's important," said study co-author Paul Coxon from Cambridge's Department of Materials Science and Metallurgy.So far this is just a proof of principle, so it'll be a while until lithium-sulphur batteries become commercially available.There are other issues to solve before that happens too - lithium-sulphur batteries still don't last as long as lithium-ion batteries.The keyword there is "rumors", however, as very few of those reports are citing trustworthy sources.
But before they become patty-worthy, each cow spends a lifetime chewing grub and burping greenhouse gases.Livestock emit 14.5 percent of all greenhouse gas emissions each year.Methane doesn t linger in the atmosphere as long as carbon dioxide—only about 20 years—but it has a much larger short-term climate impact.Methane can trap solar heat 28 times better than CO2 can, says Frank Mitloehner, an agricultural emissions researcher at UC Davis.Cow stomachs are four-chambered systems.The methane producing part—called the rumen—is a massive cavity capable of holding a bathtub s worth of saliva and cud.

The problem with pills is that you have to take them on a regular basis.An innovative new pop-up capsule solves this problem by staying in the stomach for days, where it slowly releases medication over the course of an entire treatment.This ultra long-acting oral drug delivery system was developed by researchers at MIT and healthcare firm Lyndra, and it s changing the way we think about pills.After swallowing, the capsule unfurls into a star-like shape; a configuration that prevents it from entering the digestive tract, while still allowing food to pass.The star eventually breaks down, allowing it to safely pass through the intestines.In a new study published in Science Translational Medicine, the capsules were shown to work in Yorkshire pigs weighing between 77 and 100 pounds pigs have a similar digestive system to humans .
In 2015 and early 2016, the Colorado-based restaurant chain made headlines for serving up several food-borne illness outbreaks that dramatically emptied its customer s gastrointestinal tracts.Now, the chain is making headlines for dramatically filling customers up.In a lawsuit PDF , filed November 16 in the Superior Court of Los Angeles, three nutrition-conscious patrons claim they were tricked into eating high-calorie Chorizo burritos after seeing Chipotle advertisements that suggested the swaddled meals were merely 300 calories.One plaintiff, David Desmond, realized he had been duped when he felt excessively full after eating the burrito, according to the lawsuit.Along with the other two plaintiffs, Edward Gurevich and Young Hoon Kim, Desmond is seeking unspecified damages and a class action-status for the complaint.Their suit stems from one sign in particular, seen independently by the plaintiffs in Chipotle restaurants around Los Angeles.
