New gene editing tool reduces errors by nicking DNA not cutting

As important as the CRISPR-Cas9 gene-editing tool has been, it has a relatively high error rate, which can introduce potentially harmful mutations. Researchers in Germany have now developed a more refined tool that reduces errors by nicking DNA instead… Continue reading New gene editing tool reduces errors by nicking DNA not cutting

Triple-layer bacterial biobattery produces electricity for weeks

Diversifying our energy sources is a key part of reducing our reliance on fossil fuels, and one intriguing possibility is to tap into electricity-producing bacteria. Engineers at Binghamton University have now developed a biobattery that contains three… Continue reading Triple-layer bacterial biobattery produces electricity for weeks

Atomic-scale quantum circuit marks major quantum computer breakthrough

Engineers in Sydney have demonstrated a quantum integrated circuit made up of just a few atoms. By precisely controlling the quantum states of the atoms, the new processor can simulate the structure and properties of molecules in a way that could unloc… Continue reading Atomic-scale quantum circuit marks major quantum computer breakthrough

Drug cocktail makes stem cells that could grow organisms from scratch

Researchers at Tsinghua University in China have developed a new drug cocktail that can convert cells into totipotent stem cells, the very seeds of life. These cells can differentiate into any cell in the body, potentially bypassing the need for sperm … Continue reading Drug cocktail makes stem cells that could grow organisms from scratch

Robotic fireflies light up with every flap of their wings

Engineers at MIT have added a new ability to existing flying robots – they can now glow when they flap their wings. Inspired by fireflies, this fluorescence could help with communication or tracking of the tiny, lightweight robots.Continue ReadingCateg… Continue reading Robotic fireflies light up with every flap of their wings

Graphene electronic-tattoo monitors blood pressure over time

Scientists have developed a new electronic “tattoo” that can monitor a patient’s blood pressure continuously. The e-tattoo is made of graphene and can be worn for long periods without getting in the way, allowing for better health data.Continue Reading… Continue reading Graphene electronic-tattoo monitors blood pressure over time

New cryoprotectant chemicals could preserve organs without ice damage

Getting an organ from donor to recipient is a race against time, with many going to waste. Now, researchers in Australia have identified new cryoprotectants that could preserve organs and tissues for much longer without damaging them.Continue ReadingCa… Continue reading New cryoprotectant chemicals could preserve organs without ice damage

Tightening a molecular “zipper” could help prevent hereditary blindness

Scientists in Europe have discovered a molecular “zipper” mechanism that can lead to cell death in the genetic disease retinitis pigmentosa. The good news is that injecting certain proteins could slow down or prevent vision impairment from the disease…. Continue reading Tightening a molecular “zipper” could help prevent hereditary blindness

New plant-based, antimicrobial, spray-on coating keeps food fresh

Plastic wraps and containers may be great at preserving food, but they generate huge amounts of waste that can end up in the environment. Researchers at Harvard and Rutgers have developed a new plant-based, antimicrobial coating that can be sprayed ont… Continue reading New plant-based, antimicrobial, spray-on coating keeps food fresh

Light-activated “photoimmunotherapy” kills brain cancer, reduces relapse

Scientists at the Institute of Cancer Research in London have developed a new light-activated “photoimmunotherapy” that could help treat brain cancer. The key is a compound that glows under light to guide surgeons to the tumor, while near-infrared ligh… Continue reading Light-activated “photoimmunotherapy” kills brain cancer, reduces relapse
