Superbugs and anti-vaxxers threaten global health

January 30, 2019

The World Health Organization’s (WHO) list of 10 global health threats may surprise some this year, with uninformed parents and germs straight out of a science fiction novel making the cut. Diseases that were previously pushed to the brink of eradication are making a comeback, thanks in part to the anti-vaccination movement. 


New test detects Alzheimer’s before symptoms show

January 30, 2019

According to a recent study from Washington University School of Medicine in St. Louis and the German Center for Neurodegenerative Diseases in Germany, a blood test might be able to reliably detect signs of brain damage in a person who is on the way to developing Alzheimer’s disease. This simple blood test can provide results even before the person begins showing hallmark symptoms of the disease, such as confusion and memory loss.

Virtual reality fails to stimulate real responses

January 31, 2019

Many people might recall an experience where simply looking at an image of someone yawning triggers them to yawn. This is no magic; in fact, it is a popular phenomenon known as contagious yawning. Studies in the past have shown that approximately 50 percent of adults would yawn in response to other people’s yawning.


Blood vessels in petri dish help diabetes research

January 30, 2019

Scientists at the University of British Columbia have recently made a breakthrough in diabetes research. For the first time, researchers were able to grow human blood vessels as organoids in a petri dish, which will dramatically enhance research in cardiovascular disease in patients with diabetes.


Global warming causes shorter, colder winters

January 30, 2019

Chicago natives are no stranger to arctic weather, suffering through subzero temperatures at least once a year. But this winter, temperatures are plummeting to near negative 55 degrees Fahrenheit with wind chill, making Chicago colder than even the South Pole. And the reason may be surprising: global warming.

Quadriplegics wirelessly control computer systems

December 6, 2018

Paralysis is a debilitating condition, but one that affects nearly two percent of the population in the U.S. — approximately 5.4 million people. Many paralyzed patients suffer from quadriplegia, a condition signified by partial or complete lack of motor function in all four limbs. Often the result of a traumatic injury, paralysis is caused by an inability of the spinal cord to pass signals from the brain to the peripheral nervous system.

HopAI launches with its first symposium at Hopkins

December 12, 2018

HopAI held its inaugural event on Thursday, Nov. 29. The organization, which seeks to connect and expose Hopkins students to artificial intelligence (AI), invited three speakers from different areas of study to describe their work with the diverse technologies.


Ionic wind can be used to power small planes

Bernoulli, Jurin and the math behind smallpox

December 6, 2018

In December of 1694, Mary II of England fell ill. Physicians who attended the stricken queen, half of the pair known as William and Mary, argued over a diagnosis, but before long it became clear that she had contracted a severe form of smallpox. She died three days after Christmas, and the news was carried across London by tolling bells.


Climate change caused ancient mammal extinction

December 5, 2018

While it has been a long-standing belief that pre-modern hominins, the ancestors of modern-day humans, contributed to the extinctions of large mammals in ancient Africa, researchers at the University of Utah have recently uncovered evidence that this may not be the case. Instead, these researchers believe that changes to atmospheric conditions, mainly the decrease of carbon dioxide as a result of increasing grassland, led to the extinction of these mammals.

Insomnia is a process that can be triggered by exposure to artificial light.

Artificial light can disrupt innate circadian rhythm

December 5, 2018

According to the American Sleep Association, approximately 50 to 70 million American adults experience some form of sleep disorder. The term insomnia is used to describe the inability to fall, and stay, asleep. About 30 percent of American adults report issues with insomnia, of which 10 percent report having been diagnosed with chronic insomnia. These numbers are gradually on the rise.


Perspectives on mental health around the world

November 29, 2018

The University’s undergraduate population boasts students from 62 different countries, with 11 percent of the current freshman class being international students. With this cultural diversity comes a mix of perspectives, cultures and experiences, especially in regard to mental health. In response to increased globalization over the last century, many countries have seen stigma against and support networks for the mentally ill change. Regardless, most cultures still have perspectives about mental illness that greatly reflect their regions’ traditions.

It’s not all in your head: the brain and gut connection

November 29, 2018

For as long as I can remember, my stomach has always hurt. Sometimes, I would feel like I was being stabbed with a dull knife, over and over. Other times, my body would break out in a cold sweat from waves of nausea. Even when I wasn’t in pain, my stomach would make noises, prompting people to ask what was wrong. I usually just said that I was hungry, even if I wasn’t.
