The effects of carbon dioxide (CO2) emissions are great and long reaching – a new study has found that pink salmon in the Pacific Ocean are threatened by increasing ocean acidification.
This is the article that’s gonna make you regret you weren’t paying attention in the chemistry class. Here are 16 reactions that will blow your mind: Mercury reacting with aluminum Aluminum, when it combines with oxygen, forms aluminum oxide, an incredibly hard substance that is scratch resistant. It doesn’t flake off (like iron oxide), sealing the rest of aluminum. But
In the beginning, the Earth’s surface was a lifeless, hot, but chemically rich place. In these harsh conditions, the first amino acids synthesized from inorganic compounds, and from them, proteins formed. They built the first single cells, which went on to form plants and animals. Recent research helped us understand the process that created amino acids, and there is a widespread consensus in the scientific community as to the path cells took to evolve to complex life as we know it today.
In 1921, archaeologists found the remains of a Bronze Age priestess, dubbed the Egtved Girl. Now, a new study reveals that the priestess, who was found in Denmark, likely traveled hundreds of kilometers and was born somewhere in Germany. The Egtved Girl was, according to all clues, an extraordinary person. She only lived to be 16-18. She was slim, 160 cm tall
Scientists have managed how to create morphine using a kit like the ones used to make beer at home. They used genetically modified yeast to perform the complicated process of turning sugar into morphine, and while they believe this can have huge medical significance, they also express concerns about “homebrewed” drugs.
According to a new study, just like tree rings carry with them hints about previous dry or rainy years, bones in fish carry with them a specific signature which records the chemical composition of the waters they used to live in. Most vertebrates, especially fish, have what is called an ‘otolith’ – a specific bony structure inside the inner ear. The
Graphene – the one atom thick sheet of carbon arranged in a hexagon lattice – is the strongest material known to man, and spider silk is one of the strongest found in nature, second only to limpet teeth. Heck, why not combine the two? Sounds silly, but it surprisingly worked when Nicola Pugno of the University of Trento, Italy sprayed spiders with both graphene particles and carbon nanotubes. The spiders weaved silk infused with the materials, and in some cases the silk was 3.5 times stronger than its natural counterpart. The resulting fiber is tougher than “synthetic polymeric high performance fibers (e.g. Kevlar49) and even the current toughest knotted fibers,” according to the paper published in Materials Science, which obviously entails a lot of real-life applications, industrial or otherwise.
Many beetles have defense mechanisms which involves foul chemicals squirting from their abdomens, but bombardier beetles have taken it to the next level. Researchers from MIT, the University of Arizona, and Brookhaven National Laboratory wanted to see how it works, so they studied the bombardier beetle and figured it out. The research is published in Science.
I know, the title sounds like one of those scams that promise you’ll lose weight – but this is all science all the way. Researchers in Sri Lanka have found a simple way of cooking the rice that not only reduces calories by half, but also provides other health benefits. The key addition is coconut oil.
In a most unexpected find, the same University of Manchester team that isolated graphene for the first time in 2003 found that water flattens into square crystals – a never encountered lattice configuration – when squeezed between two layers of graphene. The square ice qualifies as a new crystalline phase of ice, joining 17 others previously discovered. The finding could potentially improve filtration, distillation and desalination processes.
