The largest molecule yet found in a roiling disk of dust and gas around a baby star has been identified, scientists report. In this swirling cloud, astronomers detected the signature of dimethyl ether, a molecule that contains nine atoms. This oxygen-bearing molecule can act as a building block for sugars and other biomolecules, which means … Read more
Machines made of atoms are being used to sew together new materials molecule by molecule, which could open the floodgates to all manner of innovation Technology 2 March 2022 By Katharine Sanderson Graham Carter Simple molecular machines have existed for about two decades. Early examples include molecular wheels that could move along an axle, … Read more
If you want to truly understand what makes a machine tick, you need to tinker. Swap gears, lock a lever, loosen a spring, and watch how it goes. When the machine is a deadly virus, you can’t afford to be so cavalier with its molecular clockwork. But researchers are getting around this problem by making … Read more
Photosynthesis quite literally changed our world. Plants ‘eating’ sunlight and ‘breathing out’ oxygen transformed Earth’s entire atmosphere into the one we now breathe, and fuel our ecosystems with energy. Now researchers have caught a cunning species of bacteria with stolen photosynthesizing technology. And their molecular, light-eating device is unlike any we’ve ever seen. “The … Read more
There are few bigger questions than how life first got started on Earth, but trying to put in the detective work almost 4 billion years after the event is understandably hard going for scientists. Now it looks as though we might have found another clue. New research focuses specifically on peptides, smaller versions of … Read more
Organic chemistry, one of science’s most grueling disciplines, is poised to get a whole lot easier. Six years ago, a team of chemists created a robotic system that could construct a wide variety of organic molecules including potential pharmaceuticals, dyes, and perfumes. But the setup had limited abilities: It could build flat molecules—chains or 2D … Read more
Ground squirrels spend the end of summer gorging on food, preparing for hibernation. They need to store a lot of energy as fat, which becomes their primary fuel source underground in their hibernation burrows all winter long. While hibernating, ground squirrels enter a state called torpor. Their metabolism drops to as low as just … Read more
Organic molecules found in a Mars meteorite that crash-landed on Earth are not signs of life, but instead formed in chemical reactions between water and rock on the Red Planet about 4 billion years ago, a new study finds. These findings could shed light on the origins of the building blocks of life on early … Read more
Computer simulations of clouds of atoms and molecules must always trade scale for accuracy, but a new technique shows that both are possible at once using AI and clever coding Technology 12 January 2022 By Matthew Sparkes The Summit supercomputer at Oak Ridge National Laboratory, Tennessee ORNL and Carlos Jones Artificial intelligence has been used … Read more
Scientists have built the tiniest antenna ever made – just five nanometers in length. Unlike its much larger counterparts we’re all familiar with, this minuscule thing isn’t made to transmit radio waves, but to glean the secrets of ever-changing proteins. The nanoantenna is made from DNA, the molecules carrying genetic instructions that are around … Read more
