Did Life Originate in the Earth’s Crust?

Early Earth

This, at least, is what the geologist Prof. Dr. Ulrich Schreiber and the physico-chemist Prof. Dr. Christian Mayer of the University of Duisburg-Essen in Germany are convinced of. “It is the first model on the origin of life which includes a complete process leading from inorganic chemistry to a protocell where the problems of molecule formation, local concentration, driving force and membrane formation are being solved simultaneously” Prof. Mayer from the faculty of Chemistry says.

Novel Approach to Sex Ed

14_ART_STUDENT_WORK

Sexual Education is a divisive issue which is brought into focus each year as children face a new curriculum, but a university student has set out her own approach to the problem by turning her master’s project into a social commentary on sexuality. Read More →

Cosmic Battle and the Future of the Universe

New research offers a novel insight into the nature of dark matter and dark energy and what the future of our universe might be. Researchers in Portsmouth and Rome have found hints that dark matter, the cosmic scaffolding on which our universe is built, is being slowly erased, swallowed up by dark energy. A cosmic battle of sorts.

How does a comet smell and what can it teach us about the emergence of our solar system? Since early August, the Rosetta Orbiter Sensor for Ion and Neutral Analysis (ROSINA) has been “sniffing” the fumes of the comet Churyumov-Gerasimenko with its two mass spectrometers to answer these very questions. The detected chemistry in the coma of the comet is surprisingly rich at more than 400 million kilometers from the Sun.  Read More →

Vanadium Dioxide & Associative Processing

Science

Vanadium dioxide has some unusual properties, and it’s actually able to transition between being a semiconductor and a full conductor. That has begun to open up some interesting possibilities as far as material engineers are concerned. Penn State engineers recently developed an oscillating switch that uses the compound. Due to its ability to fluctuate between the two states, the substance was perfect as far as making a switch was concerned. Read More →

Where humans, animals and robots meet

Swarm Tech

To meet our everyday needs in an increasingly multifaceted technological world is a challenge that pushes researchers to find innovative tools using a multidisciplinary approach. We inhabit a globalized planet, made up of complex systems, where domains such as communications, business, healthcare, energy or transportation converge, interact and integrate. Read More →

The Future of Molecular Electronics

MEimg

The emerging field of molecular electronics could take our definition of portable to the next level, enabling the construction of tiny circuits from molecular components. In these highly efficient devices, individual molecules would take on the roles currently played by comparatively-bulky wires, resistors and transistors. Read More →

Nanoparticles In Rodents

When many people find stories reporting scientific research in animals, they typically assume that the content will somehow involve some aspect of genetic modification. Typically this is true, and generally these modifications are accompanied by heated ethical debates. Canadian researchers, however, have been looking into a completely different and promising technology that I thought I’d share with you today. Read More →

Evolution of Asteroid Study

Asteroid

On 13 April 2029, asteroid 99942 (heretofore known as Apophis) is estimated to come within 18,300 miles of the Earth. This alarming distance is even more shocking when one takes into consideration that modern geosynchronous satellites orbit the Earth at approximately 26,000 miles. Once the shock has cleared, there is another fact you need to take into consideration: astronomers across the globe are tracking Apophis every day. It is currently labeled as a “0” on the Torino Scale. The Torino Scale is used to categorize the likeness of an asteroid impact on Earth. Read More →

Motor-Neurons

The brain is a complicated network of small units called neurons, all working to carry information from the outside world, create an internal model, and generate a response. Neurons sense a signal through branching dendrites, carry this signal to the cell body, and send it onwards through a long axon to signal the next neuron. However, neurons can function in many different ways; some of which researchers are still exploring. Read More →
