Energy drinks risking potentially fatal heart rhythm disruption — but it’s not the caffeine, scientists find

Posted by in category: biotech/medical

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.

Priorities for the next 10 years of human microbiome research

Posted by in category: biotech/medical

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.

Sensor-packed glove learns signatures of the human grasp

Posted by in categories: biotech/medical, cyborgs, robotics/AI

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 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.

These Scientists Are 3D-Printing New Body Parts for Athletes

Posted by in categories: 3D printing, bioengineering, biotech/medical

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.

Healthy fat hidden in dirt may fend off anxiety disorders

Posted by in category: biotech/medical

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”.

Scientists discover why a promising cancer drug failed in clinical trials – and how to fix it

Posted by in category: biotech/medical

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.

This Volkswagen Prototype Has a Holographic Interface

Posted by in categories: augmented reality, biotech/medical, holograms

O.o!


In what the German automaker is calling a “world premiere,” Volkswagen’s futuristic Golf GTI Aurora concept has a high-end sound system in its trunk that can be operated with a hologram.

You can leave your 3D glasses and augmented reality gloves at home: the hologram floats freely in the air and can be operated without any external aids. Though to be fair, VW is being very vague about the details of the technology behind the interface.

Nanoparticles can aid in stroke therapy

Posted by in categories: biotech/medical, health, nanotechnology, neuroscience

Tiny selenium particles could have a therapeutic effect on ischemic brain strokes by promoting the recovery of brain damage. Pharmacologists, including Alireza Mashaghi from the Leiden Academic Centre for Drug Research discovered that selenium nanoparticles inhibit molecular mechanisms that are responsible for the loss of brain cells after a stroke. The results were published in Nature Scientific Reports in April.

Nanoparticles against strokes

An ischemic stroke happens when a supplying blood vessel to the brain is narrowed or obstructed. As a result, the brain gets too little blood. “This lack of blood can lead to brain tissue damage due to cellular toxicity, inflammation and cell death,” Mashaghi explains. “This will, in turn, lead to brain dysfunction and neurological complaints such as numbness, vision problems, dizziness and severed headache.” Ischemic stroke accounts for 87% of all strokes and is a significant cause of death. “So far, no neuroprotective agents have been shown to produce any measurable improvement in health in cerebral stroke cases. Our results now demonstrated that selenium nanoparticles inhibit molecular mechanisms that are responsible for the loss of brain cells after a stroke.”
