by Fernanda Ferreira figures by Daniel Utter There are tens of thousands of buildings in São Paulo, the largest city in the Western hemisphere and Brazil’s financial center. From the sky, São Paulo looks like a fossilized forest of concrete trees. From the ground, it’s a pulsing behemoth, every avenue crammed with cars and people. The urban sprawl of Metropolitan São Paulo engulfs 39 municipalities … Continue reading Disease Never Sleeps: Yellow fever and the importance of vaccine stockpiles in emergency epidemic prevention
by Xindi (Cindy) Hu figures by Lillian Horin In March 2017, the U.S. Environmental Protection Agency (EPA) decided not to ban Chlorpyrifos, a widely used pesticide. One year later, in February 2018, a bill was introduced in Hawaii to ban the manufacturing, distribution, and use of chlorpyrifos across all Hawaiian islands. Hawaii House Rep Richard Creagan said the legislation was prompted by the inaction in … Continue reading The Most Widely Used Pesticide, One Year Later
For as long as humans have conceived of making hybrid organisms, an ethical debate has been waged over whether or not we should. The pros and cons are vast and poignant. Each new scientific advancement towards making hybrids stokes the fire of controversy. This year, researchers presented work at a conference detailing the most recent hybrid: a sheep-human chimera. To create these chimeras, scientists used … Continue reading Scientists have created sheep that are 0.01% human
by Olivia K. Foster Rhoades On December 4th, President Trump declared both the Bears Ears National Monument and the Grand Staircase-Escalante would be reduced by 1 million acres each–an unprecedented change in federal land policy. As we near the end of 2017, four more monuments totaling 12.3 million acres in size have been slated for reduction. To put that in perspective, the state of Massachusetts … Continue reading The Scales of Federal Land Management: Balancing spacious skies and purple mountains of paperwork
by Felix Barber figures by Rebecca Senft Why are batteries important? Ask yourself what a future with a sustainable economy would look like. Such a future would likely exploit sources of renewable energy, such as solar and wind, to power the electric grid, with personal transport in the form of electric vehicles (“EVs”) that would draw their power from that same grid rather than from … Continue reading The Future of Energy Storage: A lost opportunity for the U.S.?
The world is currently experiencing its sixth mass extinction event. Species are disappearing at an estimated 1000x the expected normal rate of extinction (roughly 5 species per year). Conservation efforts around the world are trying to reduce the rate of biodiversity loss, but they are hindered by the lack of hard evidence linking conservation spending to biodiversity improvements. A team led by University of Oxford researchers … Continue reading Conservation spending proven to make a difference
The first clinical trial using the gene editing technique CRISPR was given the go-ahead by panel from the US National Institutes of Health (NIH). The trial is aimed at determining if the technique is safe for use on human subjects. As there is much we have yet to learn about genes and their expression, it is a valid concern that modifying DNA in humans could … Continue reading First Human Trial of Gene Editing Technique CRISPR Approved
