A startup says it created human sperm in a lab and used it to form embryos

Leave a Comment / Biotechnology, Medicine / Valeriano Ndeyi

Paterna Biosciences, a startup based in Utah, says it has developed functional human sperm in a laboratory and used it to create healthy-looking embryos. The company believes the method could one day allow some infertile men to have biological children. The research has not yet been peer-reviewed or independently confirmed, though WIRED was the first […]

New Synthetic Biomaterial May Repair Hearts, Muscles, and Vocal Cords

Biotechnology, Medicine / Ana Kiesse Zeleme

By integrating expertise in chemistry, physics, biology, and engineering, researchers at McGill University created a robust biomaterial capable of repairing the heart, muscles, and vocal cords, marking a significant breakthrough in regenerative medicine. “Recovery after heart damage is often prolonged and complex. Repair is difficult because the tissue must endure constant motion from the beating

Mass-Produced Mini Lung Organoids Could Help Tailor Cancer Treatments

Biomedical, Biotechnology, Medicine / Ana Kiesse Zeleme

A team of scientists has created a straightforward method for automated production of lung organoids, potentially transforming the development of lung disease treatments. These tiny structures, which contain the same types of cells found in real lungs, could allow for more efficient testing of early-stage experimental drugs without relying on animal models. In the future,

A Microrobot Moves Through the Bloodstream to Deliver Medication Precisely

Biotechnology, Medicine / Evelina Jeremias

An ETH Zurich grain-sized microrobot has demonstrated in preclinical tests the ability to navigate the bloodstream, deliver drugs precisely, and dissolve, showing promise for stroke and localized cancer treatments. The system consists of a miniature capsule that holds the drug along with iron oxide nanoparticles. Iron oxide nanoparticles let operators steer the microrobot via magnetic

Biodegradable Plastic Stronger than PET Developed

Biotechnology, Medicine / Marcílio Santos

PDCA, a biodegradable alternative to PET, boasts superior physical properties. Researchers at Kobe University engineered E. coli bacteria to produce PDCA from glucose at unprecedented levels without generating byproducts, opening new avenues in bioengineering. While the durability of plastics has driven their widespread use, it also contributes to environmental problems. Most plastics are petroleum-based, making

First-Ever Pig Lung Transplant Into Human

Biotechnology, Medicine / Jorge Paka

A genetically engineered pig lung functioned for 216 hours inside a brain-dead human, marking the first reported attempt at a cross-species lung transplant, according to Nature Medicine. The technique, known as xenotransplantation, aims to ease the chronic shortage of donor organs. Pig organs are similar in size to human ones, but their proteins often trigger

Sensors Track Biomarkers to Aid Wound Care

Biotechnology, Medicine / Ngoma Manuel

“Medical professionals typically assess wounds through visual inspection, a method often limited by subjectivity. Nitric oxide (NO), released by immune cells during inflammation, is crucial for healing as it helps coordinate the recovery process.“ Measuring nitric oxide in wounds is difficult because it degrades quickly and exists in very low amounts. Additionally, wound fluids often

Laser Exposure Unlocks a Previously Unseen Color for Humans

Biology, Biotechnology, Tech / Samilton Santos

Just when we think we’ve experienced the full spectrum of visible color, scientists have reportedly discovered a way to reveal a brand-new hue to the human eye — a color that’s never before been perceived. They’ve named it Olo. Before diving into the details, it’s worth noting how participants in the study described this color:

Just as genome sequencing maps an organism’s genetic makeup, Bryan Johnson—the investor and founder of the Don’t Die movement—wants to launch “foodome” sequencing. “We’re going to sequence the U.S. ‘foodome,’ meaning we’ll test 20% of the foods that make up 80% of the American diet—essentially the everyday staples,” Johnson said Thursday at SXSW in Austin.
