A baby in New York has undergone groundbreaking open-heart surgery during delivery, believed to be the first procedure of its kind. The historic surgery took place in early January at Maria Fareri Children’s Hospital in Valhalla, New York, and was reported by ABC News.

The baby, named Luciano after his father, was diagnosed with hypoplastic left heart syndrome, a rare congenital heart defect that typically requires several surgeries in the first few years of life. However, in this case, the condition was severe enough to warrant the use of an innovative procedure called EXIT (Ex Utero Intrapartum Treatment).

In June, a groundbreaking clinical trial revealed remarkable results for dostarlimab (brand name Jemperli), a programmed death receptor-1 (PD-1)-blocking antibody. This innovative treatment completely eradicated rectal cancer tumors in patients without the need for surgery, radiation, or chemotherapy. The results, which were published in The New England Journal of Medicine, could have life-changing implications for patients, particularly those with locally advanced rectal cancer. Traditional treatments for rectal cancer often lead to serious side effects, including loss of fertility and incontinence, making this new immunotherapy an exciting prospect for many.

The promise of dostarlimab lies in its potential to change the way rectal cancer is treated. “Today’s designation, which is based on the unprecedented 100% clinical complete response rate of dostarlimab reported to date, supports a path to help change the treatment paradigm for patients with locally advanced dMMR/MSI-H rectal cancer, who face long-term adverse quality-of-life effects,” said Hesham Abdullah, Senior Vice President of Research and Development at GlaxoSmithKline (GSK), in a December 2023 press release.

Recent advancements in technology have paved the way for the creation of more sophisticated and functional prosthetic limbs. While early prosthetics were rigid and mechanical, today’s prosthetic devices are not only softer and more realistic in appearance, but they also incorporate robotic components that expand their functionality. Despite these innovations, a significant challenge remains: most robotic prosthetics are difficult for users to control intuitively, limiting their practical use and impact on the user’s daily life.

A new development from researchers at the Italian Institute of Technology (IIT) and Imperial College London offers a promising breakthrough. In a recent paper published in Science Robotics, the team introduced a soft prosthetic hand designed to be easier for users to control through a more natural and intuitive connection between the user and the device. This prosthetic uses a novel control approach that integrates postural synergies—the natural coordination patterns of multiple fingers—with the decoding of motoneuron activity from the spinal cord.

Scientists at the Francis Crick Institute have made a groundbreaking advancement in developmental biology by creating human stem cell models that, for the first time, incorporate the notochord. This rod-shaped tissue plays a crucial role in guiding the formation of the spine and nervous system in developing embryos. The research, published on December 18 in Nature, marks a significant step forward in understanding how the human body forms during early stages of development.

The notochord is a defining feature of all vertebrates, serving as a structural guide in the developing body. It plays a key role in organizing tissues as the embryo grows, but due to its complexity, it has been notably absent in previous lab-grown models of human trunk development. This new breakthrough offers the potential to further our understanding of both normal and abnormal human development.

Researchers at Zhejiang University in China have developed a groundbreaking nanoscale sensor capable of detecting lung cancer by analyzing the levels of isoprene in a person’s breath. This innovative technology could pave the way for a non-invasive, low-cost method of early lung cancer detection, potentially saving countless lives.

Isoprene is a chemical naturally released in the breath when the body breaks down fat through a process known as lipolytic cholesterol metabolism. Studies have shown that a decline in isoprene levels may signal the presence of lung cancer. Capitalizing on this insight, the Zhejiang University team developed a highly sensitive gas-sensing material, named Pt@InNiOx, that can detect isoprene levels with remarkable precision.
