A Fallen Rising Star – Eos

With the passing of a veteran scientist, we can afford ourselves the satisfaction of looking back upon a fruitful scientific career; one with a long record of success in expanding the boundaries of our collective knowledge. Losing a young colleague before they hit their stride is a double blow. We are left bereft […]

Top 10 insights in climate science in 2020 selected by 57 leading global researchers

STOCKHOLM: With impacts from climate change threatening to be as abrupt and far-reaching in the coming years as the current pandemic, leading scientists have released a compilation of the 10 most important insights on the climate from the last year to help inform collective action on the ongoing climate crisis. In a report presented today […]

New material for solar hydrogen

New photoanodes promise high efficiencies in producing hydrogen in a climate-neutral way. Image credit: HZB Hydrogen is an important factor in a sustainable energy system. The gas stores energy in chemical form and can be used in many ways: as a fuel, a feedstock for other fuels and chemicals or even to generate electricity in […]

With the aid of the new […]

You may need to start wearing better face masks

New coronavirus variants spread more easily than earlier versions of the virus. That means you may need to upgrade your face mask, experts say. What does that mean? Many experts are recommending people wear fitted surgical masks, a cloth mask over a surgical mask, multi-layer cloth masks with a non-woven filter, or a well-fitted N95 […]

Chemists are reimagining recycling to keep plastics out of landfills

It feels good to recycle. There’s a certain sense of accomplishment that comes from dutifully sorting soda bottles, plastic bags and yogurt cups from the rest of the garbage. The more plastic you put in that blue bin, the more you’re keeping out of landfills and the oceans, right? Wrong. No matter how meticulous you […]

Genome-editing tool TALEN outperforms CRISPR-Cas9 in tightly packed DNA — ScienceDaily

Researchers used single-molecule imaging to compare the genome-editing tools CRISPR-Cas9 and TALEN. Their experiments revealed that TALEN is up to five times more efficient than CRISPR-Cas9 in parts of the genome, called heterochromatin, that are densely packed. Fragile X syndrome, sickle cell anemia, beta-thalassemia and other diseases are the result of genetic defects in the […]

An Asteroid “Double Disaster” Struck Germany in the Miocene

A Gothic church rises high above the medieval town of Nördlingen, Germany. But unlike most churches, St. George’s is composed of a very special type of rock: suevite, a coarse-grained breccia that’s formed only in powerful impacts. That discovery and other lines of evidence have helped researchers determine that Nördlingen lies within an […]

How to use advanced editing tools without ruining your photos

There’s something utterly wrong with this photo. (Harry Guinness/) With great editing power comes great responsibility—the more easily you can change things about your photos, the more carefully you have to do it. Over the past few years image editing tools have gotten more advanced, more user-friendly, and, in some cases, even completely automatic. Now, […]
