In neuroscience and biomedical engineering, accurately modeling the complex movements of the human hand has long been a significant challenge.
The procedure is the world’s first human application of a graphene-based brain-computer interface.
The Advanced Research Projects Agency for Health (ARPA-H) has awarded $45 million to rapidly develop sense-and-respond implant technology that could slash U.S. cancer-related deaths by more than 50%.
Announced today, the award to a multi-institutional team of researchers, including Carnegie Mellon University, will fast-track development and testing of a new approach to cancer treatment that aims to dramatically improve immunotherapy outcomes for patients with ovarian, pancreatic, and other difficult-to-treat cancers.
Source: Brandon Martin/Rice University. The “hybrid advanced molecular manufacturing regulator,” or HAMMR, a “closed-loop,” drug-producing implant smaller than an adult’s finger is being developed to treat ovarian, pancreatic, and other difficult-to-treat cancers. The implant, which is small enough to be implanted with minimally-invasive surgery, will be able to continuously monitor a patient’s cancer and adjust their immunotherapy dose in real time.
In the age of technology everywhere, we are all too familiar with the inconvenience of a dead battery. But for those relying on a wearable healthcare device to monitor glucose, reduce tremors, or even track heart function, taking time to recharge can pose a big risk.
For the first time, researchers in Carnegie Mellon University have shown that a healthcare device can be powered using body heat alone. By combining a pulse oximetry sensor with a flexible, stretchable, wearable thermoelectric energy generator composed of liquid metal, semiconductors, and 3D printed rubber, the team has introduced a promising way to address battery life concerns.

An MIT researcher has gotten the 30-year-old computer game Doom running on actual gut bacteria. The frame rate is really bad, as the game would take nearly 600 years to beat.
Researchers have discovered how certain cells transform to help control blood pressure by producing renin, a substance usually made by specialized kidney cells. This breakthrough could lead to new treatments for high blood pressure and vascular diseases by targeting the genomic “switch” that regulates renin production. Researchers at…
The chapter summarizes the current information available from a variety of scientifically based guidelines and resources on dietary advice for those with diabetes. It is a practical overview for health care practitioners working in diabetes management. The chapter is divided into sections by content and includes sources for further reading. A primary message is that nutrition plans should meet the specific needs of the patient and take into consideration their ability to implement change. Often starting with small achievable changes is best, with larger changes discussed as rapport builds. Referral to medical nutrition therapy (MNT) provided by a Registered Dietitian Nutritionist (RDN) and a diabetes self-management education and support (DSMES) program is highlighted.

“We now need to continue observing this star to confirm the other candidate signals,” said Dr. Alejandro Suárez Mascareño. “But the discovery of this planet, along with other previous discoveries such as Proxima b and d, shows that our cosmic backyard is full of low-mass planets.”
How close are Earth-sized exoplanets to Earth? This is what a recent study published in Astronomy & Astrophysics hopes to address as a large international team of researchers have announced the discovery of Barnard b, which orbits Barnard’s star approximately 6 light-years from Earth. This discovery is profound because Barnard’s star is the closest single star to Earth but also because Barnard b is estimated to be approximately just over one-third the mass of the Earth, or approximately three times the mass of the planet Mars.
Barnard’s star is approximately 16 percent the mass of our Sun with approximately 19 percent of its diameter. While the size of Barnard b poses the possibility that it might be Earth-like, its 3.15-day orbit puts it well inside its star’s habitable zone (HZ).
“Barnard b is one of the lowest-mass exoplanets known and one of the few known with a mass less than that of Earth. But the planet is too close to the host star, closer than the habitable zone,” said Dr. Jonay González Hernández, who is a researcher at the Instituto de Astrofísica de Canarias in Spain, and lead author of the study. “Even if the star is about 2,500 degrees cooler than our Sun, it is too hot there to maintain liquid water on the surface.”
Yet despite the attraction of OAM monopoles for orbitronics, until this latest study, they have remained a theoretical dream.
Hedgehogs hide between theory and experiment.
To observe them experimentally, hope has lain with a technique known as Circular Dichroism in Angle-Resolved Photoemission Spectroscopy, or CD-ARPES, using circularly polarised X-rays from a synchrotron light source. Yet a gap between theory and experiment has in the past hindered researchers from interpreting the data. “Researchers may have had the data, but the evidence for OAM monopoles was buried in it,” says Schüler.
