Discussing paleontology, bias and representation with Prof. Siobhan Cooke

By LAUREN PADILLA | February 21, 2019

Scientists say we have entered a new epoch. Considering the lasting impacts of human-centered destruction on the world’s flora and fauna, researchers have stressed the need to mark the end of the Holocene and the start of the Anthropocene. The Center for Biological Diversity has stated that the last time Earth’s rate of species extinction was so high was 65 million years ago, when the dinosaurs collapsed. Recent statistics show that 45 percent of Earth’s invertebrates have a “threatened” status, along with over 40 percent of amphibians and nearly 20 percent of bird species.

PUBLIC DOMAIN Researchers believe certain music genres might be linked to aggression.

Music is shown to affect mental state of the brain

By JESSICA KASAMOTO | February 21, 2019

Psychological studies show that music has an effect on the way people feel, think and behave. Music is beneficial, especially to those with anxiety and depression, but evidence has also shown that some music is linked with violent behavior.

PIXABAY Female hormones interact with certain drugs to produce an increased addictive response.

Hormone cycles lead to greater addiction in women

By TRISHA PARAYIL | February 21, 2019

Epidemiological clinical studies have shown that females are especially vulnerable to drug addiction and relapse. More specifically, females are more likely to transition to addiction soon after their first drug use and relapse, and they have greater cue-induced cravings for drugs. 

Pill with a new design can now deliver insulin

By ALLISON CHEN | February 21, 2019

For individuals with type 2 diabetes, daily insulin injections are a necessary but uncomfortable routine. A team of researchers at the Massachusetts Institute of Technology (MIT), however, have developed a pill that can deliver doses of insulin, replacing daily injections. Their work was published in the journal Science.

A new treatment could reverse some paralysis

By RACHEL HUANG | February 14, 2019

Approximately 300,000 Americans in the United States live with some form of spinal cord injury (SCI), with about 20,000 new cases each year. Vehicular accidents are the leading cause of SCIs, followed by incidences of falls, violent behaviors and mishaps during recreational activities. Depending on the severity of the SCI, these injuries may lead to paralysis in various areas of the body.

PUBLIC DOMAIN Parent’s may perceive their child’s pain differently based on their gender.

Gender might change perceived pain

By TRISHA PARAYIL | February 14, 2019

In a study published in the Journal of Pediatric Psychology, Brian Earp and his colleagues found that the perceived gender of a child influences an adult’s evaluation of that child’s pain. 

PUBLIC DOMAIN A dwarf galaxy possible as old as the universe has been discovered.

Hubble Space Telescope spots new dwarf galaxy

By CINDY JIANG | February 14, 2019

The Hubble Space Telescope is a joint project between the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) that was established in 1990 via a Space Shuttle mission STS-31 launch into low-Earth orbit. Throughout its 29-year lifespan, the telescope has contributed immensely to planetary studies, having made more than 1.3 million observations.

COURTESY OF STEPHANIE LEE Two professors at Hopkins discussed how love has changed in the U.S.

How have marriage and relationships changed over time?

By JOHN FRYE | February 14, 2019

As social media and online dating platforms like Tinder and Hinge become more and more visible in American society, people are beginning to question whether relationships and the concept of love are evolving. Many feel as though technology has superseded human interaction and elevated the desire for quick hookups, while others contend that modern relationships remain fundamentally the same as they were in prior generations.

Osler symposium discusses future of health care

By LAURA WADSTEN | February 14, 2019

The Osler Medical Symposium hosted a talk on the future of health care in America on Tuesday, Feb. 5 called “Reimagining Healthcare for the 21st Century.” The event consisted of a presentation by Dr. Redonda G. Miller, president of the Hopkins Hospital, and a discussion moderated by Perry Tsai, president of the American Medical Student Association. 

Antarctic glacier cavity points to rapid melt rate

By SHIRLEY MARINO LEE | February 14, 2019

A NASA-led (National Aeronautics and Space Administration) study recently discovered an enormous cavity, comparable to two-thirds the area of Manhattan, at the bottom of the Thwaites Glacier in West Antarctica. The cavity is much bigger than expected, a surprising find that scientists hope will lead to better models of glacial melting and their impact on sea level rise.

AMS director addresses climate change implications

By TRISHA PARAYIL | February 14, 2019

Paul Higgins, the director of the American Meteorological Society’s (AMS) Policy Program, gave a talk on Feb. 7 titled “Climate Change As a Public Issue: The Role of Science in Policy” as a part of the Randolph Bromery Spring 2019 Seminar Series.

PUBLIC DOMAIN Recently, researchers discovered that the p53 gene can both stop and accelerate cancer growth.

Is the p53 gene truly the guardian of the genome?

By AVERY GULINO | February 14, 2019

The p53 gene is widely known as a cancer suppressor gene that reduces the frequency of tumors – but what if that wasn’t the case?  The highly cited statistic that p53 mutations are found in just over 50 percent of all human cancers suggests that when the gene is not functioning properly, cancer becomes more likely.

Vocabulary learning is possible during sleep

By ALLISON CHEN | February 14, 2019

Those who have always dreamed of being a little more productive during sleep are in luck. A group of researchers at the University of Bern in Switzerland have recently demonstrated that individuals can indeed learn new words while sleeping. Their findings were reported in a university media release.

PUBLIC DOMAIN  Barklice is one of the species in which females can possess male sex organs.

Male reproductive organs can develop in females

By JESSICA KASAMOTO | February 14, 2019

Scientists have recently discovered male reproductive organs on a female insect. This finding demonstrates the significant role that evolution plays in developing male and female genitalia and also challenges the concept of sex – what it means to be male or female. 

PUBLIC DOMAIN CATCH is a new method that can detect viruses in low abundance.

Computational method detects epidemic viruses

By ELAINE CHIAO | February 7, 2019

To this day, many people still recall the widespread Zika outbreak in the wake of 2016 that caught the majority of South and North America off guard. In November 2016, the World Health Organization (WHO) declared the end of the epidemic after many months of struggle. 

Static electricity may soon help power your iPhone

By WILL EDMONDS | February 7, 2019

Though many of us experience it every day, static electricity remains somewhat poorly understood. Researchers have recently begun to look into the details behind how electricity is generated through frictional contact; that is, the molecular physics behind your hair’s propensity to stick to balloons. The research being conducted at the University of Buffalo and Kansas State University has so far uncovered some interesting twists to the electron exchange known as triboelectrification that takes place between two materials in contact with one another.

PUBLIC DOMAIN Many animal species, such as the pygmy-owl, will be affected by the proposed border wall extension. 

Building a border wall would put wildlife at risk

By SHIRLEY MARINO LEE | February 7, 2019

Although the controversy over whether or not to extend the 650-mile border wall between the United States and Mexico largely centers around immigration, it is also important to consider the effects a wall would have on the environment of the borderlands.

NASA/JPL/CORNELL UNIVERSITY NASA’s Opportunity rover might have to end its 15-year orbit on Mars.

NASA lost contact with its Mars Opportunity rover in a dust storm

By CINDY JIANG | February 7, 2019

Mars is one of the closest planets to Earth within our solar system and a strong contender for habitability under controlled conditions. Considering its unique status, it makes sense that many missions have been launched for the purpose of characterizing the planet. This would allow astronomers and scientists to better understand Mars and determine whether life could possibly exist there in the future. The National Aeronautics and Space Administration’s (NASA) Mars Opportunity rover is one of two rovers launched back in 2003 to probe Mars for any signs of past life.

PUBLIC DOMAIN The ratio of male to female births may be affected by temperature.

Global warming might mean fewer baby boys

By ALLISON CHEN | February 7, 2019

One unexpected impact of climate change may be an altered ratio of male to female children born, a recent study suggests. Research published by a team of Japanese and Danish scientists in Fertility and Sterility indicated that there is a statistically significant relationship between temperature differentials and the male-to-female birth ratio.
