| Welcome to the Sciworthy newsletter! To ring in the New Year, this month we’re celebrating scientific innovations. Science rarely moves in a straight line. Some discoveries quietly refine what we already know, while others mark true turning points—moments when new data reshape long-held ideas or push technology forward. In this issue, we explore recent findings that could signal such shifts, from breakthroughs in gene therapy to metal-mining plants and fungi-based smart materials. |

| How to Keep Good Genes On |

| 2026 is here! And one of the genetic breakthroughs from the past year could lead to a safer future for treating inherited diseases in 2026 and beyond.
Most medical treatments try to fix a problem by directly altering broken genes. But scientists have recently discovered that sometimes genes are perfectly fine. They just get switched off by tiny chemical tags attached to DNA.
Researchers at the University of New South Wales found that these chemical tags, called methyl groups, act like locks that keep genes turned off. For years, scientists debated whether these tags caused genes to shut down or simply appeared after genes were already inactivated. This study confirmed that the tags are actually the cause. When researchers removed them, the genes turned back on. When they added the tags again, the genes switched off.
This discovery marks a step forward because most gene-editing methods work by cutting DNA. Cutting DNA always carries a small risk of causing cancer, which is especially dangerous for treatments meant to last a lifetime. This new method avoids cutting DNA, which makes it much safer.
The researchers hope to use this approach to treat a blood disorder called sickle cell disease, where red blood cells become hard and curved instead of soft and round. These misshapen cells struggle to carry oxygen and move through blood vessels, causing pain and serious health issues.
Before birth, all babies produce a healthy form of blood called fetal hemoglobin. After birth, the gene that produces fetal hemoglobin is switched off, and it’s replaced by adult hemoglobin. In people with sickle cell disease, the adult version doesn’t work properly. By removing the chemical tags that keep the fetal gene switched off, scientists hope to turn it back on in adults, allowing their bodies to make healthy blood cells again.
So far, this method has worked in human cells in the lab. Animal testing will be the next step, before ultimately trying it in humans. If successful, scientists think this breakthrough could help treat many genetic diseases, without the risks that come with cutting DNA. |

| New life-saving customized gene therapy. An infant patient, designated baby KJ, was born with a potentially fatal genetic disease known as CPS-1 deficiency. People with a deficient CPS-1 gene cannot remove the toxic chemical ammonia from their livers. Scientists at Penn Medicine recently used the DNA-editing technology CRISPR to modify KJ’s genes. After 2 rounds of treatment, they found that KJ’s blood ammonia levels remained stable – a sign that his liver function and metabolism were improving. Read about it here. |

| Fungi could reshape the next generation of smart materials. What if living fungus could power our electronics, weave our textiles, and reinvent plastic as we know it? As nature’s recyclers, fungi are among the most versatile organisms. They can colonize many different surfaces, from wood to plastic, and even heal themselves. Scientists from Switzerland recently developed mixtures of living fungal fibers that can act as self-stabilizing emulsifiers, tunable films, and fast-responding smart materials in food, packaging, and electronics.

| A better way to treat canine cancer. A main cause of death in dogs is cancer, which affects about 1 in 4 dogs worldwide. Despite recent advancements in cancer research, treatment based on a dog’s genetics is still not widely implemented in veterinary care. To address this gap, scientists from Stanford examined canine cancer mutations using DNA data from over 2,000 dogs with confirmed cancer diagnoses. The team found that each canine cancer had a unique genetic signature, which could help veterinarians make more accurate cancer diagnoses and develop better treatments for our canine friends.

| Metal-tolerant plants could change the future of mining. Some plants are especially good at extracting metals like copper, lead, and nickel from the soil and storing them in their roots and leaves. Scientists hope to use these plants to “mine” metals that are important for the economy, a concept called phytomining. However, researchers don’t fully understand how these plants tolerate such high concentrations of metals. A team of researchers from France and the Netherlands described a plant that can accumulate high concentrations of nickel while experiencing only mild stress. Read about it here. |
