Findings suggest neurological basis of obesity

As the world gravitates toward the two polar extremes of body weight — obesity and anorexia — scientists struggle to determine the underlying biological causes, hoping to find effective treatments to combat these disorders.


1,000 Genomes Project reaches milestone

This month marked the first phase culmination of “The 1,000 Genomes Project,” an extensive five-year study that sought to determine the gene sequences of 1,092 individuals. The project’s well-represented research team comprised of about 400 researchers from around the world including Aravinda Chakravarti, a member of the Institute of Genetic Medicine at the Hopkins School of Medicine.

Cope’s Law: Could dinosaurs have been bigger?

You may have heard of island gigantism, an interesting phenomenon in which small animals that migrate to islands tend to grow significantly larger. However, Cope’s Rule, which was proposed by an American paleontologist Edward Cope in the late 19th century, takes the “bigger is better” perspective a few steps further.


ADHD drugs prescribed to failing students

Imagine the elementary school student who tries his best, who does her homework, who stays out of trouble. The one who still has to come home to parents with a lousy report card because of an inadequate schooling environment.


New planet found near Earth’s solar system

History was made when a team of astronomers based in Geneva recently discovered a new planet orbiting Alpha Centauri B, a star that is the galactic equivalent of a saunter from BLC to the library away from us.  The new planet was — not too creatively — named Alpha Centauri Bb.  This is not only the most recently discovered planet, but also the closest planet to our solar system ever discovered.


Mosquito proteins function like antibodies

Our immune systems rely on antibodies to target pathogens like malaria parasites through their ability to recognize specific proteins and other tell-tale molecules. Mosquitoes, however, do not have these antibodies and rely instead on a recently-discovered gene.


Retina swelling shows brain damage

The retina is a tissue lining the inner wall of the eye. The sensory cells, namely the rods and cones, of the retina pick up electrical signals from when the light hits the eyes, thereby allowing us to see the world.


Beneficial mold added to crops

Although agriculture may no longer be on the minds of Americans as much as it was in the 1800s, its importance in the American economy cannot be ignored. According to the United States Environmental Protection Agency, the value of commercial vegetables in the United States last year was $12,820,274, while the value of field crops came out to $171,393,620,000. Not a small sum at all.


Sandy forwarns future storm strength

Hurricane Sandy is the largest recorded Atlantic hurricane in diameter. It started as a tropical wave in the Caribbean on Oct. 22, and then became a tropical depression. This means that groups of thunderstorms have organized and that there is very low pressure, especially in the center of these storms. Six hours after it became a tropical depression, it was upgraded to a tropical storm, defined as a storm with winds from 39-73 mph. It has also become organized enough to start to look like the pictures of hurricanes we see on The Weather Channel. It was upgraded to a hurricane on Oct. 24, right before it hit Jamaica. It went back into the water and built up strength, upgrading to a Category 2 hurricane before striking Cuba on Oct. 25. A Category 2 hurricane, with winds from 96-110 mph, can cause a lot of damage, especially to objects and buildings that aren’t firmly rooted in the ground. It weakened to Category 1 (74-95 mph) and then became a tropical storm on Oct. 27, but quickly moved back to hurricane status. It hit the United States on Oct. 29 at around 8 p.m., slightly south of Atlantic City N.J. It was declared a post-tropical cyclone around 7 p.m., which means that the storm system became colder and connected with cold-weather fronts.


Nitrogen may be new eco-friendly fuel for cars

If you’re lucky and your hometown is Los Angeles, you may have seen the crimson-colored, Honda FCX Clarity or silver Mercedes-Bentz F-cell station wagons on the street as owners drive by smugly, feeling great that the only emission coming out of their car is water.


Sports bra uses temperature to detect breast cancer

Breast cancer will affect one in eight American women during their lifetime and 39,510 women will die from the disease this year alone, according to data released by the National Cancer Institute. These statistics have created a race to develop an effective screening method for breast cancer.


JHU alum steered shuttle Endeavor to L.A.

We all know that Hopkins alumni include a president of the U.S and a mayor of NYC, but who would have expected that one of our alums would end up snagging a space shuttle?  After a nearly 20 year career, the Space Shuttle Endeavour recently completed its journey to its new home at the California Science Center (CSC) in Los Angeles.  Hopkins alum Ken Phillips, Curator for Aerospace Science at CSC, was instrumental in bringing the shuttle to Southern California.


Shah discusses international public health work

Busy making an impact on the world, Maunank Shah, an assistant professor at the Hopkins School of Medicine, gave a public health lecture this past Monday. Lambda Epsilon Mu hosted Shah’s lecture, “Infectious Disease Control: Bridging the gap between clinical care, research, public health, and health policy,” in Charles Commons.


Physicists prepare to launch FORTIS

On Dec. 15 this year, a team of Hopkins scientists will send a rocket on a 400 second journey from the historic White Sands Missile Range in New Mexico through earth’s atmosphere and beyond.


Intel winner revolutionizes cancer detection

Jack Andraka, high school sophomore and Grand Prize winner of the 2012 Intel International Science and Engineering Competition, presented his research at a talk hosted by Beta Beta Beta, Hopkins University’s biology honor society, this Monday, Oct. 22.


Apple plays catch up with some new releases

Tech giants have vied for attention this week with many major announcements and unveilings, and Apple did not want to be outdone. At their media event on Tuesday, Apple recapped the successes they have enjoyed thus far with the iPhone5 and iOS6, the revamped iPod lineup, and the new software features to boot.


Unpleasant noises activate amygdala

Who still remembers cringing from the high-pitched screeches of your grade school teacher pressing down on chalk a tad too hard? For those of you with younger siblings, what about the time when you were rudely awakened up in the middle of the night from the baby’s bloodcurdling screams?


Students present cancer research

The Institute for NanoBioTechnology held a mini-symposium on cancer research in the area of nanotechnology on Wednesday. The event, held in the Clipper Room of Shriver Hall, was an opportunity for several graduate students to present their projects in cancer research to others in the field.
