We’ve previously told you how our ancestors’ adaptation to metabolizing alcohol which first happened some 10 million years ago may have been essential to their survival. There’s more to it though. The same enzyme that metabolizes alcohol, dehydrogenase (ADH4), may be eventually used to transform CO2 into alcohol, which could be later used as a […]
DNA is widely recognized by its double helix, but if you look at the molecule through a microscope you might be disappointed. That’s because the double helix is an atomic model, and you’d need a really powerful microscope to see the helix. On a grander scale, DNA can take some interesting shapes. Take for instance […]
Scientists have made a significant step towards developing fully artificial life – for the first time, they demonstrated evolution in a simple chemistry set without DNA. In a way, the researchers showed that the principle of natural selection doesn’t only apply to the biological world. Using a simple a robotic ‘aid’, a team from the University of […]
A team of UK researchers led by none other but Nobel Laureate Andre Geim – one of persons involved in graphene’s discovery in 2004 – has shown that the wondrous two dimensional material graphene can used as a proton exchange membrane in fuel cells. The find took everybody by surprise since no one expected graphene could […]
It might not come as a surprise to hear that the world’s strongest material, graphene, was found to be a great impact absorber as well. After all, there always seems to be a study that adds to the growing list of graphene’s useful properties, be its lightness, flexibility, or electrical conductivity. It’s been labeled as […]
Researchers at University of Utah have demonstrated for the first time a working biological fuel cell that uses enzymes to convert jet fuel into electricity; all at room temperature. Fuel cells are much cleaner and efficient at producing energy than internal combustion engines – theoretically, fuel cells can be up to four times more efficient since […]
Whether you enjoy a strong malty taste, or a fruity savor, or even just a subtle aroma in your beer – you have yeast to thank for. Yeast imbues beer with aromatic molecules that account for most, if not all of the final flavor. But why is it that they create all this wide array of […]
We live in a solar system filled with water. Not only does liquid water cover 72% of our planet Earth, we have also found ice water in asteroids and comets, on the Moon, on Mars, and even in the shadows of craters on Mercury; while Europa and other moons of Jupiter and Saturn almost certainly […]
Yeast is already used to create two substances widely used to kill pain – beer and wine. Jokes aside, researchers have shown that genetically modified yeast can create morphine, which would remove the need for poppy crops – something which is currently causing widespread issues (including war) in some areas. “Opiates and related molecules are […]
For the first time, scientists at Penn State University have coaxed carbon-containing molecules to form a strong tetrahedron shape, then linked each tetrahedron end to end to form a long, thin nanothread. The resulting materials is stronger than carbon nanotubes, while the thread is only a few atoms across thick, hundreds of thousands of times smaller than […]
Though betavoltaics – battery technology that employs radiation as a means of power generation – has been around since the 1950s, developments thus far haven’t been the most promising. This may set to change after researchers at University of Missouri reported they’ve devised a nuclear-assisted battery, which works in a watery environment, that both lasts longer […]
Stanford researchers traced back methane leaks from contaminated drinking water in Pennsylvania and Texas to shale gas wells. However, they note that they did not find a link between the contamination and the technique used to drill for shale gas itself, called hydraulic fracturing or more commonly known as fracking. Instead, the researchers concluded that […]
As microbes become more and more resistant to antibiotics and cleaning products, it’s crucial that we find better, more efficient way of fending them off. Dr. Samir Mitragotri from the University of California at Santa Barbara has led a team which showed that ionic liquids (ILs), also known as liquid salts, dramatically improve the treatment of microbial […]
Since it was first introduced decades ago, mass spectrometry has proved to be an invaluable tool for analyzing the chemical makeup of foods, pharmaceuticals, forensic remains and so on. The equipment, however, is extremely bulky, expensive (in the hundreds of thousands range) and a sample might take days of back and forth analysis before results […]
One of the most famous chemistry experiments of the last century was the ‘primordial soup’ project initiated by Stanley Miller. The chemist wanted to see what would happen if you mixed methane, ammonia and hydrogen – all substances readily available on Earth before life began – and zapped them with electricity, to create a phenomenon analogous to […]
For billions of years, nature has been harnessing the energy from the sun through photosynthesis. This way, plants, algae and cyanobacteria use sunlight to split water and produce energy-rich chemical compounds from carbon dioxide (CO2). This energy is then transferred to animal that eat these plants, and animals that eat plant-eating animals, including us humans. It’s […]
A while ago I wrote about the disheartening status quo of energy today: frack now, ask questions later. In the article, I argue that there’s a disproportion between the amount of hydraulic fracturing (9 out of 10 wells in the US are fracking wells) and the number of research articles that discuss the bio impact […]
Chemists led by Nobel laureate K. Barry Sharpless have used what is called click chemistry to uncover unprecedented, powerful reactivity. This opens a new “chemical galaxy” of molecules, potentially paving the way for making drugs, plastics and unprecedented smart materials. Click chemistry is a term applied to chemical synthesis tailored to generate substances quickly and reliably by joining […]
A group of international researchers have demonstrated a novel technique for destroying cancer cells. By inserting a chloride payload that penetrates the cancer cell's sodium membrane, the cells become flushed with salt causing a self-destruction response.
Brown University researchers reported the development of a copper foam which could turn CO2 into useful chemicals such as formic acid – a preservative and antibacterial agent in livestock feed.

Scientists have found a much more efficient way of converting CO2 into methanol, using a catalyst with oxide nanoparticles. The resulting system makes the conversion almost 90 times faster than currently existing systems.
Ionic liquids (IL) are basically liquid salts with very low melting points, that are extensively used in industry. It's only recently that an ionic liquid has been found to occur in nature, after a team of researchers at University of South Alabama found that the substances forms when two ant species mix their venom.
While scientists have been studying and incrementally increasing solar cell efficiency, we’ve yet to reach nature’s magnitude of solar energy conversion through photosynthesis. Artificial photosynthesis is a goal in alternative energy research, yet the process is extremely difficult to mimic since, in nature, the process involves numerous stages and transformation of matter and energy. Purdue University […]
If you’ve owned a smartphone or laptop for more than two years and use the gadgets frequently, then you’ve most likely noticed, to your exasperation, how short the battery life is compared to when the product was first shipped.

In an awesome feat of atomic manipulation, physicists from the University of Basel, in cooperation with team from Japan and Finland, have placed 20 atoms atop an insulated surface in the shape of a Swiss cross. Such […]
You might have thought black is too solemn or boring, but you may just change your mind. Through careful material science manipulation, involving thousands of tightly packed carbon nanotubes, British company Surrey NanoSystems made a super black coating that absorbs almost 99.96% of visual light – a world record. Practically only a tiny fraction of the visual […]
Researchers have detected the smallest force ever recorded – 42 yoctonewtons – using a system of super-cooled atoms. Yocto-what? The Newton, named after sir Isaac Newton, is the international unit of measure for force. 1 Newton is equal to 1 kilogram times 1 meter over 1 second square (1N = 1 kg * 1 m […]
Chemical researchers at Penn State and Shinshu University report they’ve managed to isolate strong, stretchable graphene oxide fibers that are easily scrolled into yarns and have strengths approaching that of Kevlar. The fiber can be then further refined to act as a powerful and lightweight electrical conductor or can be directly used as a higher […]
Since its advent some 100 years ago, crystallography has become one of the most important processes in chemical research and development. It involves bombarding a material with X-rays to produce a diffraction pattern as they reflect off the sample. The pattern can be used then to directly determine the atomic structure of the crystal. Using […]
When we think of CO2 emissions, we generally tend to think of air pollution and global warming; we tend to ignore the fact that a huge part of all the CO2 emissions is absorbed by the oceans, and the oceans are becoming more and more acidic. The process is just getting started, and it’s gonna […]
Plants can communicate with each other, signaling a potential incoming attack through an underground network of fungi, researchers found. Instances of plants communicating with each other have already been picked up through the air – with chemicals emitted by one plant being picked up by another plant. But below ground? They rely on fungi called mycorrhizae. A […]
It’s a good day to be a chemist – a new, super-heavy element has been added to the periodic table after it was discovered by a team Germany’s GSI laboratory. The periodic table was (and still is) the foundation for modern chemistry – it is a tabular arrangement of all the chemical elements, organized on […]
Water is liquid, air is gaseous, but glass? For years at end, glass has perplexed scholars intending on fixing it under a state of matter. Neither liquid, nor solid, explaining glass is a lot harder than some might think. Researchers at Duke University have contributed to solving the puzzle after they performed numerical solutions and […]
A team led by Jonathan Coleman at Trinity College Dublin reports they’ve patented a technique that can easily produce large quantities of quality graphene. The method is so simple that the researchers have even been able to scale it down for use in a kitchen blender. The exact ‘recipe’ has yet to be disclosed, but nevertheless […]
Part of an extraordinary venture, researchers at the U.S. Naval Research Laboratory (NRL) report they’ve synthesized hydrocarbon fuel solely from seawater by transforming the CO2 and H2 found in the water.

Scientists at Queen Mary University of London and the Cambridge Graphene Centre found that […]
Reliable, well supplied and with years and years of manufacturing experience behind it, copper is the most widespread material used for delivering electrical charge. Some applications warrant more efficient materials, though, and researchers at Rice recently showed that carbon nanotubes spun into fiber can carry four times as much electrical charge than copper cables of […]
Sometimes, I come across stories or various research that make me wonder “why the heck hasn’t anyone else thought of this before?” We should be grateful, nevertheless, that researchers from University of Texas at Dallas have found a way to manufacture artificial muscle that is up to 100 times stronger than the flimsy tissue that […]
One of the biggest arguments against renewable energy deployment on the truly massive scale is their unreliability. Justly so, wind doesn’t always blow at desired velocities and the sun fluctuates in sunshine throughout the day. With this in mind, if you don’t have a back-up storage medium, intermittent renewables will always be an alternative – […]
Graphene, a 2-D array of carbon atoms arranged in a hexagon shape, is one of the most researched material today. We’ve written extensively before about its properties and uses, and indeed the future seems to belong to graphene where it’s sure to dominate the electronics industry. Before this can happen, however, graphene production and manipulation […]
Fuel cells are absolute wonders of technology – electrochemical systems that directly convert the chemical energy of a fuel (hydrogen and oxygen) into electricity and heat. There’s no combustion, and consequently fuel cells aren’t limited by the same thermodynamic cycles as a typical heat engine. A theoretical efficiency of 70% is thus reached – which […]
Carbon nanotubes and graphene have been hailed time and again as the wonder materials that will change the face of technology in the future.
