Study finds barriers to expressing gratitude

By TRISHA PARAYIL | September 27, 2018

A study conducted by Amit Kumar and Nicholas Epley at the University of Chicago (UChicago) found that people routinely undervalue the benefits of expressing gratitude. Their findings suggest that the disconnect between the expresser’s expectations and the recipient’s experience may prevent people from conveying gratitude, such as through sending letters that increase positive feelings for the recipient and expresser.

The brain’s opioid system may lead to overeating

By RACHEL HUANG | September 27, 2018

Most people have had the experience of being full, yet still eyeing the plate of fries sitting at the end of the table. As friends and families continue to chat around the dinner table after a three-course meal, hands continue to subconsciously reach out, time after time, for more food. But what physiological process actually takes place when someone becomes excessively full from food?

Technology has come a long way, from using a telegraph to transmit morse code to high-speed computers and touchscreen phones that can do virtually anything. It has expanded to encompass a large part of daily life with a wide array of applications. Technology continues to branch out into various other disciplines and has already helped to make huge strides in improving the quality of health care.

Hopkins issues 24 new BME recommendations

By JAEMIE BENNETT | September 27, 2018

Hopkins may be best known for its medical training, but it also has a more-than-sizeable dent in the biomedical engineering (BME) world. BME scientists at Hopkins research everything from electronic models of hearts tailored for a single patient to using molecular mechanisms in a cell to pinpoint a disease.

CRISPR treats Duchenne Muscular Dystrophy

By JAEMIE BENNETT | September 20, 2018

Since the first successful use of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) as a gene editing tool in 2013, CRISPR has become a large topic of conversation both in science and at the dinner table. Recently, CRISPR has been used to treat Duchenne muscular dystrophy (DMD), the most common fatal genetic disease, in dogs. If it proves successful in humans, it could potentially cure DMD.

Scientists explore ways to harness sustainable energy

By JESSICA KASAMOTO | September 20, 2018

With global warming such a hot button topic in today’s day and age, it is unsurprising that scientists have been continually searching for new renewable sources of energy that don’t harm our planet. While hydroelectric and solar energy are now common energy sources, scientists have seemingly combined the two practices in new studies at Ludwig Maximilian University of Munich (LMU) in Germany: Researchers at the university have split water molecules using solar energy. This could be a promising renewable energy source for future generations.

Birds are losing homes due to deforestation

By CINDY JIANG | September 20, 2018

The cloud forests of Honduras are a sight to behold, as they are characterized by a low-level cloud cover at the canopy level. Also known as a montane rainforest, this region has heavy rainfall and constant condensation in the air, a result of the cooling of moisture-laden air currents deflected upward by the mountains. Moisture is abundant from water vapor, and due to elevation and climate conditions, the ecosystem is fed directly by clouds.

How a military operation led to a cure for malaria

By ALLISON CHEN | September 20, 2018

In the jungles of Vietnam in the 1960s, at the same time as they were fighting one another, American and North Vietnamese forces were both battling drug-resistant malaria. The disease was living up to its storied history of being an absolute pain for military commanders, undeterred by therapies that had lost effectiveness due to widespread and often haphazard use.

Waterworld planets have the potential to host life

By ALYSSA WOODEN | September 13, 2018

For years, astronomers have been exploring the question of whether life exists on planets other than Earth. Advances in technology have allowed for more extensive research into exoplanets, or planets outside our solar system. Water worlds (also known as deep ocean planets) are a specific type of exoplanet that are completely covered by ocean, which can be hundreds of miles deep.
