Tiny protein pairs may hold the secret to life’s origin A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences across thousands of species, the researchers revealed that these molecular pairs trace the earliest steps in the origin of life.

Goodbye colonoscopy? Simple stool test detects 90% of colorectal cancers Scientists at the University of Geneva have created the first detailed catalogue of gut bacteria at the subspecies level, unlocking powerful new ways to detect colorectal cancer. By applying machine learning to stool samples, they achieved a 90% detection rate—nearly matching colonoscopies, but with far less cost and discomfort. This breakthrough could revolutionize early cancer screening, helping catch the disease before it advances.

Scientists just found the “master switch” for plant growth Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they created a gene expression atlas that identifies rare stem cell regulators, links them to crop size and productivity, and offers a new roadmap for breeding resilient, high-yield plants.

Scientists are closing in on Leonardo da Vinci’s DNA A groundbreaking project is piecing together Leonardo da Vinci’s genetic profile by tracing his lineage across 21 generations and comparing DNA from living descendants with remains in a Da Vinci family tomb. If successful, the effort could reveal new insights into Leonardo’s health, creativity, and even help confirm the authenticity of his works.

Cannabis use may quadruple diabetes risk A massive study of over 4 million adults has revealed that cannabis use may nearly quadruple the risk of developing diabetes. Despite some earlier suggestions that cannabis might have metabolic benefits, this large analysis found significantly higher diabetes rates among users, even after adjusting for other health factors.
