Here’s another reason for children to do their chores: washing dishes by hand boosts children’s immune system. The findings were reported by Swedish doctors who found that in households where dishes are washed by hand children have much fewer allergic incidents than in those where the dishes are washed by a machine. Yet again, the findings […]
We know that things like eye or skin colour are encoded in our DNA and passed down by our parents, but many other traits are significantly influenced by another hereditary mechanism: bacterial offspring. A paper in Nature suggests microbes are passed down from mother mice to pups, passing down traits similarly to how genes influence illness and health.
A new liquid-infused polymer can make sure that medical equipment is bacteria free by being extremely slippery. This technology, which involves silicone infused with a silicone oil also has a myriad of potential applications outside of medical equipment - in the oil industry, in air planes and cosmetics.
Researchers in Germany report the discovery a previously unknown bacterial communication pathway, one that might be a potential target for new medicine.
A new study has found that chewing gum is actually effective at cleaning your mouth of bacteria - but only if the gum is sugar free. If the gum has sugar, it actually feeds the bacteria even more.
Using innovative microfluidics devices, US researchers were able to study thousands of bacteria individually, something extremely difficult if not impossible to do in the past, and found that generation by generation bacteria actually change their size and shape, but collectively retain the same volume. The bacteria stick to this behavior as if governed by a rule or law; something that might help explain why animal organs are always of particular size and shape, why are individual cells of a particular shape for that matter or, ultimately, what is it that regulates all this.
The bright, rainbow-colored thermal pools of Yellowstone park may owe their spectacular color to tourist pollution, a new study suggests. Using mathematical models, the study showed the initial colors of the ponds – the ones they had before tourists started polluting them. Morning Glory Pool is a hot spring in the Upper Geyser Basin of […]
Among evidence analyzed during a rape-related crime investigation, one of the best clues that might incriminate a suspect are pubic hair samples. But because these hairs most often than not are missing their roots, it’s very difficult if not impossible to make a conclusive DNA analysis. Silvana Tridico, a forensic biologist at Murdoch University in Perth […]
One of the most fundamental question evolutionary biologists are trying to answer is how did multicellular life evolve from single celled organisms. Researchers from New Zealand, Germany and the USA believe they have found a counter-intuitive hint after studying organisms evolve in real time: cheating, non-cooperative cells may have pressured evolution to work on a program that […]
Houses of the future might be built with bacteria – at least partially. It may sound like science fiction, but a Spanish company located in Madrid is working to make that a concrete reality. It all starts with a common type of soil bacterium being. Put it in some soil, provide it with nutrients, and keep the […]
Researchers at the University of Bristol used a complex computer simulation to determine how enzymes in bacteria breakdown antibiotics, rendering them useless. The same simulation could be used to see how certain drugs respond to various bacteria, predicting their resistance and efficacy. This way, doctors will be able to prescribe the best antibiotics for a […]
Our gut hosts an enormous population of bacteria, each species with its own niche (they feed on certain foods), which outnumbers our own cells 100-fold. Most of these bacteria are good bacteria, though. In fact, you couldn’t survive without most of them! They’re among the best decomposers, breaking down dead and organic matter otherwise impossible […]
Cellular biology can be breathtakingly exciting. Just imaging peering through the absolute tiniest forms of life – a whole different universe in itself! Many times, in this cellular universe, you witness chaos, but here’s where Brazilian multidisciplinary artist Vik Muniz and self-described “bacteria enthusiast” Tal Danino come in. The two paired and launched an ambitious […]
Bacteria living in obscure environments use an extremely rare process to harvest energy and produce oxygen from sunlight – but they don’t use visible light, they use far-red light. “We have shown that some cyanobacteria, also called blue-green algae, can grow in far-red wavelengths of light, a range not seen well by most humans,” said Donald […]
Scientists introduced Clostridium novyi, a bacteria that causes mild illnesses in humans that typically lurks inside the soil and feces, in cancer tumors and found that these shrank and some cases were destroyed completely. The research suggests that bacteria, when engineered to reduce toxicity, can be a viable fighting tool against cancer, one with less destructive […]
You could be sitting alone and still be completely outnumbered for your body is home to trillions upon trillions of tiny passengers – bacteria. In fact, there as ten times more bacteria living inside you then cells in the body. Don’t get scared, though. The vast majority of these co-redident organisms are our friends. They […]
It’s a truly terrifying story, and a truly terrifying disease. The flesh-eating culprit in question is called GAS, or Group A β-hemolytic streptococcus, a highly infective bacteria. Apart from causing the flesh-eating disease necrotizing fasciitis, GAS is also responsible for a range of less harmful infections. But like most bacteria, it was harmless at one point in its […]
An international team of scientists believe they have across the “microbial Pompeii” after they found preserved bacteria and microscopic particles of food on the surface of teeth more than 1,000 years old. The findings were made after the dental calculus or plaque that covered the ancient teeth was analyzed. Some very important discoveries were made in the process: ancient […]
Researchers at MIT found that individual cells in a bacterial colony will grow in a manner that is beneficial to the whole culture, even if this comes at a personal expense for the cell. With this in mind, it appears seemingly complex colony structures can be explained by an essentially simple behaviour. The findings could […]
Drug resistant bacteria (immune to almost all antibiotics) are dreaded by patients and physicians alike. Finding them in hospitals is bad enough as it is, but failing to detect them is even worse – it can result in a dramatic outbreak. This is why patients with bacterial infections are typically screened using automated lab tests […]
Your gut is home to some 100 trillion bacteria – more than the entire number of cells in the whole human body. Clearly, bacteria are fond of human intestines, as we humans, unknowingly or not, are fond of them. After all, without bacteria our organisms would be deprived of extremely vital vitamin sources and digestion […]
An estimate 20% of Americans use some of form of psychotropic medication, amounting to a $34 billion industry. Desperate to ease their problems away with one magic pill, people are flocking in pharmacies to take their regular hits of Prozac, Valium or Vicodin. In the future, however, a new class of drugs may enter the […]
To say that finding evidence of how life on Earth was 3.5 billion years ago is hard would be an understatement. Reconstructing the rise of life in its early stages is a monumental challenge – the evidence is only preserved in Earth’s oldest sedimentary rocks, and sedimentary rocks of that age are very hard to […]
Researchers have found that methane-decomposing bacteria from hot springs need rare earths to produce the energy they need to survive. Rare Earth Elemenets (REE), or rare earth metals as they are sometimes called are a group of 17 chemical elements in the periodic table, specifically the so-called lanthanides plus scandium and yttrium. They are among […]
A drug treated with a special dye allows doctors to monitor real-time bacterial growth. Despite advancements in technology and despite all the effort put in by doctors, bacteria often manage to sneak onto medical implants such as bone screws, where they cause severe, possibly life-threatening infections. A new research published in Nature Communications suggests using […]
It almost seems too good to be true – a novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source, while also improving the efficiency of the waste water system. A sustainable, self-driven system In a paper published in the American Chemical Society journal ACS Nano, a […]
How do organs such as the heart or kidneys know when to stop growing? A number of theories have been proposed to answer this, the most entrenched of which dating back from 1952, when the infamous Alan Turing used math to show how biological cell patterns form and how these knew when to stop division. Turing […]
Faeces based treatment halts the advance of Clostridium difficile bacteria, but a commercial treatment is still far away. Using a faeces in the treatment of the gut infections and diarrhea is not a new idea, though it’s still in its initial stages. In 2010, we told you about a woman who had a life threatening […]
Loliginidae, also known as pencil squids, are formidable animals that can change their colour matching their surroundings really fast and effortlessly. For centuries the only thing man has learned from them is how tasty they are. Now, researchers at University of California, Irvine, found there’s much more to them then a simple calamari dish. The scientists […]
A surprisingly diverse range of life forms exists deep in the oceanic crust, but they live at an extremely slow pace. Long lived bacteria, which reproduce only once in 10.000 years, have been found in rocks 2.5km below the ocean floor, rocks which are 100 million years old. Viruses and fungi have also been found […]
Our bodies are hosts to some hundreds of thousands of bacteria that live in harmony with each other, helping the body be healthy, in return for the food and shelter it provides to these tiny organisms . Collectively, all the microorganisms inside the human body are referred to as the microbiome, most of whom are […]
It may not seem like much, but by differentiating between bacterial and viral fevers, this new test could help doctors decide whether or not to prescribe antibiotics. Fevers are a common symptom in many infectious diseases, but it’s often difficult to know if the cause is bacterial or viral, and thus, antibiotics are often needlessly […]
A team of researchers from the US claim they have finally found tangible evidence that will once and for all end the controversy surrounding the Geobacter sulfurreducens, a bacteria that conducts electricity along thin protein filaments, just like a metal. In the scientists’ paper, it’s reported that aromatic amino-acids are central to both the electrical and respiratory functions […]
A team of researchers at Princeton University have devised an experimental set-up that closely mimics the flow of bacteria through working medical devices. Their findings show that bacteria clog medical devices extremely fast – much faster than previously thought – and warrant new strategies and designs in order to counter machine failure. The researchers used […]
Researchers at Tufts University School of Medicine came across a particular strain of bacteriophage – a virus that infects and replicates within bacteria – that had stolen the functional immune system of the cholera bacteria. The virus used the bacteria’s immune system against it to replicate and eventually kill the bacteria. The findings hint to the prospect of developing new […]
It’s a bird! No, it’s a plane! No, it’s… microbes ?! High up in the atmosphere, 10.000 meters above ground, researchers have found over 100 species of bacteria doing just fine in stormy clouds. Each year, hundreds of millions of tons of dust, water and man-maned pollutans make their way into the atmosphere, often traveling […]
About one in three breads is thrown away because it gets too tough and infected, and thus inedible, because of mold. Scientists at an American company have found a way to keep bread fresh for up to two months after they zapped it in a sophisticated microwave array. This killed the bacteria and fungi that […]
The reason why we don’t trade with gold, diamonds or cheese is because these do no offer the exact interchangeable value. Money the other hands, does. If you loaned someone with $50, and the other person returned the money all in coins for instance, you’d still have the same exact value back in your hands. A new […]
According to researchers, thousands and thousands of bacteria types (some new to science) can be found in your belly button – but don’t worry: “it’s quite beautiful”, they say. A pristine environment The belly button is one of the microbial habitats closest to us, yet it remains relatively unexplored. Rob Dunn and his team analyzed […]
Bacteria biofilms, when formed, pose a significant health risk in industrial applications, like food processing, and medical settings. Researchers at MIT suggest a new weapon for fighting bacterial formations in the form of nature’s own line of defense – mucus. Mucus lines most of the wet surfaces of the body, including the respiratory and digestive tracts, […]
In an extremely exciting find, scientists at Aarhus University in Denmark found a type of bacteria that creates electrical currents on the sea floor. Despite the lack of air or sun light, these tiny bacteria flourish and form vast swaths of electrically pulsating multi-cellular organisms. The researchers found that the bacteria breaks down substances in deeper sediments […]
Remember when, in 2010, we told you about a team of researchers which claimed they found a bacteria that feasts on arsenic, instead of phosphorous? The study has spurred quite the discussion, receiving a lot of both criticism and praise, but seeming to be, ultimately, incorrect (as this other study also claims). Dan Tawfik, who […]
In what can only be described as a milestone in biological and genetic engineering, scientists at Stanford University have, for the first time ever, simulated a complete bacterium. With the organism completely in virtual form, the scientists can perform any kind of modification on its genome and observe extremely quickly what kind of changes would […]
By creating this microbiome catalog, researchers hope to figure out the complex interactions between the countless microbes in our bodies and our immune system. As many already know, germs are not always bad for you – in fact, they are sometimes necessary for a healthy body. But regardless how careless or careful you are with […]
Darwin’s theory of natural selection illustrates perfectly what evolution is all about, the survival of the fittest if you will. It’s because of natural selection that a crocodile has an armor-like skin to protect it against enemies, a chameleon can change its color and camouflage itself for protection and hunting or humans evolved a more […]
Researchers studying marine bacteria in the Bahamas’ underwater caves, have made some remarkable discoveries which allowed to understand how these organisms adapt and thrive in rather precarious conditions. Their study might help scientists understand how marine life formed for the first time millions of years in the past, as well as hint how marine life […]
We at ZME Science love futuristic designs, but above all we love innovative energy efficient solutions. The latest avantgarde lighting set-up from Philips would fit better in an art gallery than in a home, however what it lacks in practicability, it more than makes up in beauty, and moreover in principle – that energy is […]
Scientists at London’s Imperial College have successfully managed to create biological logic gates, indispensible for the production of electronical devices, simply our of bacteria and DNA. Though the research detailed in a recently published study in the journal Nature Communications was anything but simple, it provides an incredible advancement in the field of biotechnology. “Logic […]
Ever since uranium has been mined and atomic bombs have been tested, some areas have had to deal with the contamination of sediments and groundwaters by toxic soluble uranium. Now, this problem could be solved with filaments growing from a specific bacteria. Some clean-up methods already use the bacteria to solidify Uranium in sediments, but […]
The oldest, up to now, fossil has been found recently by a team of Australian and UK geologists, who claim that they’ve managed to discover micro-organism remnants as old as 3.5 billion years. These tiny living cells were actually sulfur feeding bacteria, which didn’t need any kind of oxygen to survive. The fossils were found […]
