A New York hospital has announced a groundbreaking milestone: a patient has been cured of sickle cell anemia using a cutting-edge genetic therapy. Cohen Children’s Medical Center reports that 21-year-old Sebastien Beauzile is the first New Yorker to receive Lyfgenia, a treatment developed by Bluebird Bio. Since undergoing the therapy in December 2024, Beauzile has been free from the disease’s debilitating symptoms, including skin ulcers, joint pain, and chest pain—marking what he calls his “new birthday.”

Sickle cell disease is caused by a genetic mutation that deforms red blood cells, impairing their ability to transport oxygen. Until now, bone marrow transplants were the only potential cure. Lyfgenia changes that equation by introducing healthy adult hemoglobin into the patient’s bone marrow, allowing the body to generate normal red blood cells. Dr. Jeffrey Lipton, director of pediatric hematology at Cohen Children’s, called the therapy “a fix” and suggested it could one day replace bone marrow transplants as the standard of care.

Gene therapy is rapidly transforming the landscape of sickle cell treatment. In a separate case, 20-year-old Brandon Baptiste appears to have been cured using base editing, a novel approach that doesn’t rely on CRISPR. After participating in an experimental trial, Baptiste has returned to an active lifestyle, including regular exercise. These breakthroughs signal a promising shift in the fight against sickle cell anemia, offering hope that more patients will soon have access to lasting, life-changing solutions.

Researchers at the University of Helsinki and the New Children’s Hospital at Helsinki University Hospital have developed the MAIJU smart jumpsuit, a groundbreaking tool that offers an objective, at-home method for assessing infant motor development. Traditionally, early neurological development has been monitored through short clinical visits and parental reports—methods that can lack consistency and detail. MAIJU provides a more accurate and continuous alternative, enabling healthcare professionals to track a child’s motor milestones without needing to be physically present.

Motor development is especially critical during the first two years of life, serving as a key indicator of a child’s overall neurological health. The MAIJU suit—short for Motor Assessment of Infants with a Jumpsuit—is embedded with multisensor technology and powered by AI-driven analysis. It is designed to be worn during natural, unstructured play at home, capturing rich data about a child’s movements, postures, and transitions between developmental stages.

By analyzing this data, MAIJU can provide detailed, month-by-month insights into a child’s progress, helping detect potential delays or concerns earlier than traditional methods allow. The innovation holds promise for improving pediatric care by making motor assessments more accessible, consistent, and precise, ultimately supporting healthier developmental outcomes for children around the world.

Astronomers have confirmed the existence of four exoplanets orbiting Barnard’s Star, the closest single star to Earth, following decades of false leads. These small, rocky worlds—previously undetectable with older instruments—were identified using the radial velocity method, which tracks the subtle “wobbles” in a star’s movement caused by an orbiting planet’s gravitational pull. Barnard’s Star, a red dwarf just six light-years away, has been a prime target for exoplanet searches for over 50 years, but traditional methods, like detecting dips in starlight, failed due to the planets’ tiny size.

“It’s a really exciting find—Barnard’s Star is our cosmic neighbor, and yet we know so little about it,” said lead study author Ritvik Basant, a doctoral student at the University of Chicago. The newly discovered planets, classified as sub-Earths, range from 19% to 34% of Earth’s mass and have incredibly tight orbits, all within the distance of Mercury’s orbit around the Sun. The closest completes a full orbit in just three days, while the farthest takes seven. They were detected using the MAROON-X instrument on Hawaii’s Gemini North telescope, which offers the precision needed to spot such small planetary signals.

Although these planets are likely barren, exposed to intense radiation and stripped of any atmosphere or water, their discovery provides valuable insights into planetary formation. Sub-Earths like these may have a broader range of compositions than larger exoplanets, offering fresh perspectives on the diversity of planets in our galaxy. The findings, published in Astrophysical Journal Letters, mark a significant step forward in understanding the hidden worlds orbiting nearby stars.

In the wake of recent global events, most adults have gained a basic understanding of the human immune system. However, a groundbreaking study from Israel has uncovered a surprising and overlooked component of immunity—one that could lead to an entirely new class of antibiotics. Despite more than a century of research, scientists have now identified the proteasome, a cellular structure known for recycling damaged proteins, as a key player in the body’s defense against bacterial infections.

When bacteria like Salmonella invade a cell, the proteasome transform damaged proteins into powerful antimicrobial compounds. These compounds attack and break down the bacteria’s outer membrane, effectively neutralizing the threat. “We discovered a novel immune mechanism that helps defend against bacterial infections,” said Professor Yifat Merbl from the Weizmann Institute of Science. To test this process, researchers exposed mice with pneumonia and sepsis to the proteasome’s antimicrobial compounds. The results mirrored the effects of conventional antibiotics, while blocking proteasome function made the mice more vulnerable to infection.

Dr. Lindsey Edwards, a microbiology expert at King’s College London, highlighted the significance of this discovery, noting that since these antimicrobial compounds are naturally produced by the body, they could lead to safer, faster-developing antibiotic treatments. With antibiotic resistance posing an escalating global threat, this finding opens the door to innovative medical solutions. “In the past, we’ve searched the soil for new antibiotics,” Dr. Edwards said. “It’s remarkable to find a potential solution inside our own bodies—thanks to advances in technology that allow us to detect these mechanisms.”
