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.

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.

10(Z)-hexadecenoic acid, a fatty acid found in the soil based bacterium Mycobacterium vaccae, interacts with immune cells to inhibit pathways that drive inflammation and increases resilience to stress. Researchers say the findings could bring us one step closer to developing a microbe-based “stress vaccine”.

Surviving fragments of genetic material preserved in sediments allow metagenomics researchers to see the full diversity of past life — even microbes.

As promising as some treatments are in lab tests, unfortunately they don’t always meet hopes when translated to the real world. Now, scientists at Whitehead Institute for Biomedical Research have investigated a class of cancer drugs that failed in human trials, and found out why. Better yet, they went on to identify another drug that could finally make the treatment work.
