Light-activated propulsion spins bacteria-shredding micromotors

The four spikes on a new nanocrystal developed in Spain spin up under light and move through liquid, blasting any bacteria unfortunate to be in their path. The development could spell trouble for bacteria that resists traditional drug treatments.Contin… Continue reading Light-activated propulsion spins bacteria-shredding micromotors

Completely new type of “biological entity” discovered in our bodies

Our bodies are home to trillions of microbes, including bacteria, viruses, fungi, and a whole host of others. Now, Stanford scientists have discovered an entirely new class of biological entities inside us, which they’ve ominously named “Obelisks.”Cont… Continue reading Completely new type of “biological entity” discovered in our bodies

Yeast with 50% synthetic DNA engineered in breakthrough genetic studies

Scientists have hit a major milestone in a 15-year project trying to build a completely synthetic yeast genome. Reporting in a bumper crop of new papers, the team has engineered viable yeast cells with more than 50% synthetic DNA for the first time, an… Continue reading Yeast with 50% synthetic DNA engineered in breakthrough genetic studies

Mini marvels mesmerize in Nikon Small World photomicrography awards

From striking close-ups of an igniting match to a mouse embryo and a micrometeorite, the winners of the annual Nikon Small World photomicrography competition have been unveiled. As always, this year’s stunning images capture the wonder of the tiny hidd… Continue reading Mini marvels mesmerize in Nikon Small World photomicrography awards

46,000-year-old worms revived from permafrost belong to new species

In what sounds like the opening scenes of a disaster movie, scientists recently revived worms frozen in the permafrost since the Ice Age. Now, these worms have been attributed to a new species, and seem to have passed down their incredible hibernation … Continue reading 46,000-year-old worms revived from permafrost belong to new species

Synthetic lifeform regains lost “fitness” in evolution experiment

How small a canvas can evolution work on? Scientists have experimented with a synthetic lifeform designed to have the simplest possible genome, and found that given the chance it can evolve lost fitness back, showing that indeed, “life finds a way.”Con… Continue reading Synthetic lifeform regains lost “fitness” in evolution experiment

Fossilized steroids reveal “lost world” of mysterious organisms

Scientists have discovered evidence of a “lost world” of previously unknown lifeforms that inhabited Earth between 800 million and 1.6 billion years ago. Fossilized fat compounds were identified in rocks all over the world, likely produced by our ancie… Continue reading Fossilized steroids reveal “lost world” of mysterious organisms

Evolution experiment yields yeast 20,000x bigger and 10,000x tougher

Scientists are conducting a long-term experiment on evolution in the lab, to investigate how single-celled organisms could evolve into multicellular lifeforms. After thousands of generations, their yeast grew 20,000 times bigger and 10,000 times toughe… Continue reading Evolution experiment yields yeast 20,000x bigger and 10,000x tougher

Newly discovered cold-adapted microbes digest plastic at low temperatures

Swiss scientists have discovered new cold-adapted microorganisms that can degrade different types of plastic at temperatures lower than currently required. The discovery is the first step towards developing a more cost-effective, industrial-scale metho… Continue reading Newly discovered cold-adapted microbes digest plastic at low temperatures
