Super nanners! Engineering bananas to save vision, life in East Africa

A new banana, genetically engineered to produce ample amount of provitamin A, has hit the news. They’re heading for human trials in the US and to the fields of Uganda by 2020, if all goes well for the Australian and Ugandan scientists developing them. Vitamin A deficiency is the leading cause of preventable blindness among children. 250,000 to 500,000 children are blinded by vitamin A deficiency each year. In East Africa, vitamin A deficiency is common and bananas are a staple crop. If these orange hued bananas make it to market, farmers maybe able to lift quality of life simply by swapping yellow fruit for orange. Continue reading Super nanners!

Genetically modified yeast and Science Fiction

About two months ago we published a short report on a new study that pioneered creating an entire chromosome of yeast; an organism with similar cellular organization as humans. Just a week ago, a discussion flared up on Reddit about the consequences for everything from creating human brain-less organ farms to custom babies. The study will really only benefit basic sciences and advanced biotechnology, where people use … Continue reading Genetically modified yeast and Science Fiction

3D Printing – Why all the hype?

3D printer making a small building. Image credit: Tiia Monto, http://commons.wikimedia.org/wiki/File:3D_printer2.jpg In recent years, 3D printing has drawn a lot of attention to itself with breakthroughs in various industrial applications.  Given the relatively recent explosion in press, it may surprise you then to learn that the first 3D printer was actually built in 1983 – over 30 years ago – by Charles (Chuck) Hull, a … Continue reading 3D Printing – Why all the hype?

Exploring Planets Near and Far

Presented by Anjali Tripathi How many planets are there? What are they like? In this lecture, we will talk about the variety of planets that are found beyond the Solar System. These so-called exoplanets have been discovered near and far, throughout the Galaxy. We’ll talk about the detection of these planets and their location in space, as well as their location relative to their host … Continue reading Exploring Planets Near and Far

Diatoms: Nature’s nanotechnologists

Microscopy images above show two model diatom species: Thalassiosira pseudonana (left) and Phaeodactylum tricornutum (right). If you live in Boston, nanofactories of sophistication well beyond anything the human race has come up with are just a Charles River away. Diatoms (seen in the images above) are unicellular photosynthetic microalgae that can be found in freshwater and marine environments worldwide. These tiny creatures have plastids with … Continue reading Diatoms: Nature’s nanotechnologists

A distant galaxy acts as a giant magnifying glass

From “Detection of the Gravitational Lens Magnifying a Type Ia Supernova“ The supernova of PS1-10afx was seen in 2010 and extremely bright for its class and location ~9 billion light years away. New research suggests that a galaxy in front of it, invisible in the bright light, had acted as a giant magnifying lens for the light on its way to Earth. This finding, when … Continue reading A distant galaxy acts as a giant magnifying glass

Photosynthesizing the Netherlands

This artistic representation of the artist’s love for his home country was made by spreading a single-celled photosynthetic bacterium called Synechococcus elongatus on a plate containing just water and some salt. These bacteria, belonging to a larger phylum of bacteria called cyanobacteria, grow by photosynthesis using little more than sunlight and CO2 and some researchers hope they can be used to produce biofuels and other … Continue reading Photosynthesizing the Netherlands

Engineering a minimal yeast chromosome: a small, but significant step forward

How can we create a fully synthetic organism? One promising way to begin would be to take an existing organism and engineer a new set of chromosomes from that organism’s genome. Scientists at NYU have created a fully synthetic chromosome for Saccharomyces Cerevisiae, the yeast that’s used in bread and beer. By stripping out ‘junk DNA’ and adding in new genes that make future genome … Continue reading Engineering a minimal yeast chromosome: a small, but significant step forward

Inflation of the Universe!

We may know that the universe began with a Big Bang, but until yesterday, we had no direct evidence for the drastic expansion the universe is thought to have undergone in the moments after its birth. This “inflationary” model has grown from a speculation in 1979 into the best available explanation of how the universe’s infant moments (less than a trillionths of a trillionth of a second) formed crucial aspects of our universe today. Continue reading Inflation of the Universe!

Math in Nature: Finding order in chaos

Presented by Jessica Kunke, Lei Zhu, Stephen Portillo The natural world is so complex and unpredictable that it might seem math could never be a sufficient tool to understand it.  Our lecture aims to widen this view of math and explore how mathematical models and chaos theory give us insights into nature.  The first part of our lecture introduces the concepts of math models and … Continue reading Math in Nature: Finding order in chaos
