A groundbreaking way of measuring fluid buildup in the body allows chronic heart failure patients to monitor their condition and treat it independently with a physician-approved response.

Tel Aviv-based startup Vectorious has created a tiny pressure sensor that is implanted directly into the heart. It is the only sensor in the world that measures the pressure in the left atrium (one of the heart’s two upper chambers) and is able to identify increases in that pressure caused by a buildup of fluid in the body.

This data on the left atrial pressure (LAP) is then transmitted to an app for the patient and their doctor.

Researchers at the National Graphene Institute have made a groundbreaking discovery that could revolutionise energy harnessing and information computing. Their study, published in Nature (“Control of proton transport and hydrogenation in double-gated graphene”), reveals how electric field effects can selectively accelerate coupled electrochemical processes in graphene.

Electrochemical processes are essential in renewable energy technologies like batteries, fuel cells, and electrolysers. However, their efficiency is often hindered by slow reactions and unwanted side effects. Traditional approaches have focused on new materials, yet significant challenges remain.

The Manchester team, led by Dr Marcelo Lozada-Hidalgo, has taken a novel approach. They have successfully decoupled the inseparable link between charge and electric field within graphene electrodes, enabling unprecedented control over electrochemical processes in this material. The breakthrough challenges previous assumptions and opens new avenues for energy technologies.

McDonald’s (MCD) will put an end to its AI drive-thru partnership with IBM (IBM) in late July as many customer complaints over botched orders began to mount. The fast-food chain does have plans to continue implementing AI into its business model down the line.

The Morning Brief Anchors Brad Smith and Seana Smith break down the latest developments for McDonald’s and what it means for the company moving forward.
