Untangling DNA with a droplet of water, a pipet and a polymer

Researchers at KU Leuven developed a simple and effective way to untangle DNA using a 'rolling droplet' technique. The method involves injecting genetic material into a droplet of water and dragging it over a glass plate covered with a sticky polymer, resulting in longer and straighter DNA strands that can be studied under a microscope.

New filter could advance terahertz data transmission

University of Utah engineers create a filter for separating different frequencies in the terahertz spectrum, a key step towards utilizing this bandwidth for commercial use. The filter can be fabricated using an off-the-shelf inkjet printer and has the potential to boost data transmission rates by thousands of times.

Life 'not as we know it' possible on Saturn's moon Titan

Researchers at Cornell University have modeled a methane-based, oxygen-free life form that can metabolize and reproduce like life on Earth. The theorized cell membrane, called an azotosome, is composed of small organic nitrogen compounds and shows stability and flexibility similar to Earth's phospholipid membranes.

Study: High stress for new mothers increases secondhand smoke risk for infants

A recent study found that new mothers experiencing higher social stressors have a 2.5 times higher odds of having only partial or no restrictions on smoking in their home, exposing infants to secondhand smoke. The researchers identified statistically significant socio-demographic and socio-economic trends in home smoking rules, highlig...
