Study shows engineered gut bacteria can treat hypertension

Newly published research proves that it's possible to treat high blood pressure by using specially engineered Lactobacillus paracasei to produce a protein called ACE2 in the gut, reducing gut angiotensin II and, in turn, lowering blood pressure. The study, done in lab rats that are predisposed to hypertension and unable to naturally produce ACE2, opens new doors in the pursuit of harnessing our body's own microbiome to regulate blood pressure.

How quantum light 'sees' quantum sound

Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales. And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications... Read more ›

New technology 'game changing' for pregnant women with diabetes

New research shows that automated insulin delivery technology could be a game changer for pregnant women with type 1 diabetes.  The technology -- known as 'hybrid closed-loop technology' -- gives insulin doses as informed by a smartphone algorithm. The new study shows that it could help pregnant women better manager their blood sugars compared to traditional insulin pumps or multiple daily injections. Lead researcher Prof Helen Murphy from UEA said:... Read more ›

Smartphone attachment could increase racial fairness in neurological screening

A new smartphone attachment could enable people to screen for a variety of neurological conditions, such as Alzheimer's disease and traumatic brain injury, at low cost -- and do so accurately regardless of their skin tone. The attachment fits over a smartphone's camera to capture clear video of pupil size changes, which can offer clues about an individual's neurological functions. The device helps the camera see the pupil easily in... Read more ›

Superdeep diamonds provide a window on supercontinent growth

Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research. These findings demonstrate that superdeep diamonds can provide a window through space and time into the supercontinent growth and formation process. Read more ›

People who communicate more, show expertise are more likely to be seen as essential team members

A new study sheds light on the vital role of communication and expertise within organizations, revealing their impact on group performance. Researchers examined how individuals become part of communication networks and the effect of selection processes on group performance. The study found that people who communicated more during training were more likely to be chosen as a central member of the network. In addition, teams that chose their central member... Read more ›

Researchers identify 'switch' to activate cancer cell death

A research team has identified a crucial mechanism on a specific cell receptor that can cause cells to self-destruct. Being able to activate the receptor -- Fas -- and trigger cell death could open the door for improved cancer treatments. Modulating Fas may also extend the benefits of chimeric antigen receptor (CAR) T-cell therapy to solid tumors. Read more ›

Researchers probe molten rock to crack Earth's deepest secrets

An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its magnetic behavior and reactivity in chemical reactions, and can influence whether iron prefers to be in the molten or solid rock.  Read more ›

Simulating cold sensation without actual cooling

The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature. Read more ›
