Making the 'human-body internet' more effective

Researchers at Tokyo University of Science have made significant breakthroughs in human body communication (HBC), which uses the human body as a network to transfer information. By analyzing the characteristics of impedance and electrodes, they found that HBC can be used to design more efficient devices with better user interaction.

Enhanced human Blood-Brain Barrier Chip performs in vivo-like drug and antibody transport

A new microfluidic organ chip model of the human blood-brain barrier has been developed, allowing for in vivo-like transport of drugs and therapeutic antibodies. The model recapitulates the physical barrier functions and transport abilities of the human BBB, offering a significant advance in drug development.

Sensing food textures is a matter of pressure

A study by Penn State researchers found that the ability to detect food textures is related to individual differences in pressure sensitivity. The study involved 111 volunteer tasters who were asked to perceive different textures in chocolate, with those who could detect grittiness being more accurate. This research may have implicatio...

Researchers developing new treatment that could protect people with cardiovascular disease

Researchers have developed a new medical therapy that could protect people with cardiovascular disease by boosting the body's natural defences. The treatment, which is based on a peptide called apelin, has shown promising results in mice and humans, reducing mortality rates and improving health outcomes.

Environmental oxygen triggers loss of webbed digits

Researchers found that atmospheric oxygen exposure triggers removal of interdigital webbing during embryo development. This mechanism is thought to be shared by all tetrapods and contributes to limb shape variation. The study provides insight into the evolutionary process behind limb development in animals.

Novel communications architecture for future ultra-high speed wireless networks

IMDEA Networks researchers have developed a novel communications architecture for future ultrafast wireless networks that promises to achieve data rates previously only possible with optical fiber. The architecture uses angle information to rapidly align directional millimeter-wave antennas and integrates a location system, enabling hi...

The app teaching anorexics to eat again

A new approach to treating eating disorders involves teaching patients with anorexia how to eat normally, with promising results. The method, which uses a smartphone app to track and regulate food intake, has been shown to achieve a 75% remission rate after just one year of treatment.

Patients at a reduced risk of venous thromboembolism and persistent pain after partial versus total knee replacement

A study published in EULAR 2019 found that patients with osteoarthritis who undergo partial knee replacement have a 25-50% lower risk of venous thromboembolism, but an increased risk of revision compared to total knee replacement. The long-term benefits of partial knee replacement are offset by the higher risk of revision.

Gut microbes eat our medication

A study published in Science reveals that certain gut bacteria can degrade levodopa, the primary treatment for Parkinson's disease, by converting it into dopamine outside the brain. Researchers identified Lactobacillus brevis as a key player in this process and found a molecule capable of inhibiting the bacterial enzyme responsible. Th...

Taking the 'killer' out of natural killer cells

Researchers have discovered a previously unreported strategy employed by the virus responsible for chickenpox and shingles to powerfully inhibit natural killer cell function. This impairment enables the virus to paralyze natural killer cells, rendering them unable to respond to target cells, thereby evading the immune response.
