Molecular crowding inside cells is a critical factor that is sometimes overlooked in the lab. Biochemical reactions are drastically different in tighter spaces, resulting in significant physical and chemical consequences.

DNA Could Predate Existence of Life As We Know It

primordial-earth-before-life

Chemists are close to showing that DNA could form spontaneously from chemicals which were present during primordial Earth. If they succeed, the work could imply that DNA could predate the birth of life as we know it.

First Integrated Chemical Circuits Developed Using Ion Transistors

chemical-circuit

A the Organic Electronic research group at Linköping University in Sweden, researchers have been working on ways of creating chemical circuits. They were previously able to develop ion transistors to transport both positive and negative ions as well as biomolecules. Now, Klas Tybrandt has succeeded in combining both transistor types into complementary circuits, which are similar to silicon-based electronics.

Livermorium & Flerovium, Two New Elements Officially Join Periodic Table

periodic-table-livermorium-flerovium

It was first announced back in December 2011 that two new elements would join the periodic table of elements. It has now become official. Flerovium and Livermorium, elements 114 and 115, were approved by the International Union of Pure and Applied Chemistry on the 31st of May.

Olympicene, the Smallest Possible Five-Ringed Structure

olympicene-afm

The smallest five-ringed structure possible is about 100,000 times thinner than a human hair, and it was created by a collaboration between the Royal Society of Chemistry (RSC), the University of Warwick and IBM Research in Zürich. Scientists used a combination of synthetic chemistry and modern imaging techniques to create olympicene.

Elastomeric “Soft” Robots Running on Pneumatic Actuators

elastomeric-robots-soft

These new prototype robots, which were molded from paper and silicone rubber, can twist, bend, grip, and lift more than 100 times their own weight. The more astonishing fact is that they run on pneumatic actuators, which means that they basically run on air.

Humans Implicated in Africa’s Deforestation 3,000 Years Ago

deforestation-wwf-human

A new study published in the journal Science suggests that humans might have played a significant part in the sudden deforestation of rainforests from Central Africa. This work contradicts the prevailing view that the expansion of farming practices was the root cause as well as the increased incidence of long, severe dry spells.

Chemistry Might Influence Habitable Zones Around Extrasolar Systems

kepler-field-of-view

Trace elements in extrasolar systems might influence the evolution of habitable zones around their stars, where carbon-based life as we know it might dwell. Most stars are made up of hydrogen and helium gas, but there still remain traces of heavier elements, like metals, that are inherited from the remnants of older stars or forged by stellar fusion.

Self-Healing Polymer Mechanism Rediscovered After 60 Years

self-healing-polymer

There’s been a lot more research into self-healing organic polymers, but it’s only recently that a self-healing mechanism from more than 60 years ago was rediscovered. The process, which is called siloxane equilibration, allows silicone rubber that’s been cut in half to completely repair itself through heat-activated reversible bonding.
