If you’re planning a trip to Hawaii, be mindful of what you eat, the state’s Department of Health states in an advisory published last week. Officials are ramping up efforts to warn tourists about rat lungworm disease, an illness caused by a parasite that can infest human brains. The advisory follows an alert from the CDC that confirmed three new rat lungworm cases all linked to Hawaii.
Two studies are shedding light on the links between the gut, the brain, and autism. The research reveals how gut problems can be triggered by the same gene mutations associated with autism, and a study shows how a fecal transplant from humans with autism can promote autism-like behaviors in mice.
The newest results from the Human Microbiome Project have revealed just how connected the microbes in our gut are to our overall health.
You have about as many bacteria and other microbes living in your body as your own cells—and yet, we still don’t understand much about how this microbiome relates to bodily function. Back in 2007, the National Institutes of Health kicked off the Human Microbiome Project, a $200 million effort to understand these microbes. Scientists have now published the results from the second phase of this project, designed to study how the microbiome interacts with the human body. These three studies, which examine preterm birth, inflammatory bowel disease, and pre-diabetes, demonstrate that microbiomes are unique to individuals and intimately tied to our health.
Scientists at the University of Helsinki working in collaboration with the University of Oxford have deciphered for the first time how a virus genome is condensed inside the capsid of a virus.
“The motivation of the study was to increase our basic understanding of viral replication, but in the long term this may contribute to tackling viral disease,” says the director of the of the project, Associate Professor Juha Huiskonen from the Helsinki Institute of Life Science, HiLIFE.
The breakthrough results were achieved using cryogenic electron microscopy, a method that has in recent years revolutionised structural biology—a field of biology that aims to understand how molecules of life work at the atomic level.
We found that eating one cup of blueberries per day resulted in sustained improvements in vascular function and arterial stiffness—making enough of a difference to reduce the risk of cardiovascular disease by between 12 and 15 percent.
Eating a cup of blueberries a day reduces risk factors for cardiovascular disease—according to new research led by the University of East Anglia, in collaboration with colleagues from Harvard and across the UK.
New findings published today in the American Journal of Clinical Nutrition show that eating 150g of blueberries daily reduces the risk of cardiovascular disease by up to 15 percent.
The research team from UEA’s Department of Nutrition and Preventive Medicine, Norwich Medical School, say that blueberries and other berries should be included in dietary strategies to reduce the risk of cardiovascular disease—particularly among at risk groups.
Energy drinks are causing potentially fatal heart disorders that are not explained by their high caffeine content, a study has found.
Experts have warned people with congenital heart conditions and high blood pressure to limit their use of the drinks after the largest study yet found they caused substantial interference in the electric signals that govern the organ.
A trial of participants between the ages of 18 and 40 revealed the speed at which the heart reset itself after beating was altered at least four hours after consuming an energy drink.
In my view, most of the research so far has placed too much emphasis on cataloguing species names. We’ve been characterizing the human microbiome as if it were a relatively fixed property to be mapped and manipulated — one that is separate from the rest of the body. In fact, I think that interventions that could help to treat conditions such as diabetes, cancer and autoimmune diseases will be discovered only if we move beyond species catalogues and begin to understand the complex and mutable ecological and evolutionary relationships that microbes have with each other and with their hosts.
The dream of microbiome-based medicine requires a fresh approach — an ecological and evolutionary understanding of host-microbe interactions — argues Lita Proctor.
Wearing a sensor-packed glove while handling a variety of objects, MIT researchers have compiled a massive dataset that enables an AI system to recognize objects through touch alone. The information could be leveraged to help robots identify and manipulate objects, and may aid in prosthetics design.
The researchers developed a low-cost knitted glove, called “scalable tactile glove” (STAG), equipped with about 550 tiny sensors across nearly the entire hand. Each sensor captures pressure signals as humans interact with objects in various ways. A neural network processes the signals to “learn” a dataset of pressure-signal patterns related to specific objects. Then, the system uses that dataset to classify the objects and predict their weights by feel alone, with no visual input needed.
In a paper published in Nature, the researchers describe a dataset they compiled using STAG for 26 common objects—including a soda can, scissors, tennis ball, spoon, pen, and mug. Using the dataset, the system predicted the objects’ identities with up to 76 percent accuracy. The system can also predict the correct weights of most objects within about 60 grams.
A team of bioengineers has successfully 3D-printed tissues they believe doctors could one day implant into patients to help heal the knee, ankle, and elbow injuries that have ended the careers of countless athletes.
“I think this will be a powerful tool to help people with common sports injuries,” Rice University researcher Sean Bittner said in a press release — though the impact of the group’s work could extend far beyond the turf or pitch.
