Using light, scientists could reduce alcohol withdrawal symptoms in rats.

Scientists could “turn off” alcohol cravings

It’s nearing midnight and you’ve spent a productive day in Brody. You’ve had dinner, but you’re feeling a bit hungry after all the time working on that assignment for that class you have. All of a sudden, you get a craving — French fries. Cravings are a common occurrence, but have you ever wondered exactly what it is that drives them?


Humans may be able to sense magnetic fields

It’s a process that allows pigeons, honey bees and whales to navigate the world through the Earth’s magnetic field. Magnetoreception, a so-called sixth, geomagnetic sense, is found in bacteria, arthropods and multiple vertebrate species. It was thought to be completely beyond the perception of beings humans.

A study at the University of California, Santa Cruz showed that solitude could have benefits.

Study shows solitude can be good for mental health

In this day and age, depression amongst college students is a growing issue: According to the National Alliance on Mental Illness (NAMI), more than 10 percent of all college students have been diagnosed with depression. While many may believe that a telltale sign of depression can be social withdrawal and isolation, new studies conducted at the University of California, Santa Cruz (UC Santa Cruz) show that this may not always be the case; in fact, young adults who spend time alone can gain many benefits from this chosen solitude.

Scientists came up with a new genetic method to revert blindness.

Gene insertion helps blind mice regain eyesight

First evolved in animals 550 million years ago, the ability to see is essential to life. It helps animals navigate the world around them. Researchers at the University of California, Berkeley (UC Berkeley), may have found a way to reverse blindness caused by retinal degeneration and give people back the ability to fully experience the world.

O’Keefe highlights the disparities in Native American communities.

Meet the Hopkins professor tackling health equity for indigenous communities

Addressing disparities in Native Americans’ access to healthcare and quality of treatment is a critical public health issue. In a joint survey from National Public Radio, the Robert Wood Johnson Foundation, and Harvard’s T.H. Chan School of Public Health, almost a quarter of Native Americans reported having faced discrimination during a doctor’s visit. Approximately 15 percent of participants indicated that the fear of encountering bias from medical professionals prevented them from pursuing healthcare services.

Redfield’s prediction, stated in an interview with the New York Times on March 15, came after his visit to the affected region. 


New discovery may reveal origin of the solar system

Nothing is impossible. This statement is perhaps best embodied by the planetary sciences, a field in which scientists have made so many discoveries that seem so far removed from the normal everyday. Take the Big Bang for instance. It is a familiar concept to many, but scientists don’t really have any primary sources for the actual event.

In the US, Hispanics and blacks are plagued the most by air pollution.

Study finds air pollution affects minorities most

While racial inequalities are evident in the United States when it comes to disparities in categories like wealth, educational opportunities and unemployment rates, a recent public health study has shown that racial inequality exists when it comes to air pollution as well.

HIV occurrences had decreased form 2010 to 2013, but since then they have plateaued.

Reduced HIV incidence in the U.S. has stalled

A new report on the incidences of human immunodeficiency virus (HIV) in the United States reveals that the decline in HIV infections has plateaued as the Trump administration reveals its intention to end the HIV epidemic by 2030.


Genetics might play a role in healthy marriages

The secret behind a successful marriage may be more than just passion. According to a new study, genetics may also play a role. Yale scientists found that a gene responsible for emotional stability may also predict marriage satisfaction. This may pave the way for a future study on how genetics can impact the quality of relationships over time.


Wrap up: the latest in technology...

Elizabeth Warren campaigns in New York City  Known as a strong critic of tech giants, U.S. Senator Elizabeth Warren recently held a campaign event in New York City, where the tech conglomerate Amazon was recently effectively pushed out. She gathered an audience of more than 1000 people who listened to her speak about “tech companies who think they rule the earth,” among other issues. Much of her plan is driven to protect the people’s interests and protect smaller competitors from tech monopolies. The official Democratic-presidential candidate’s policies would push existing tech giants to divest in their acquisitions. In addition, she would implement laws that limit a tech giant’s influence and participation in its own platform.

A pair of semi-identical twins in Australia share only 78% paternal DNA.

Doctors identify first case of semi-identical twins

A strange pregnancy puzzled doctors in Australia. An initial ultrasound showed two embryos sharing a placenta, which normally indicates monozygotic, or identical, twins. But weeks after, another ultrasound revealed the two fetuses had different sexes, a seeming contradiction to the earlier discovery.
