Senior Neha Skandan's journey to becoming an Astronaut Scholar

By GRACE OH | September 17, 2024

Every year, around 60 undergraduate researchers are awarded the Astronaut Scholarship by the Astronaut Scholarship Foundation (ASF). The ASF is a nonprofit organization created by the Mercury 7 astronauts, and its mission is to support scholars in STEM fields as well as honor the legacy of American astronauts. One of these scholars, Neha Skandan, is a senior double-majoring in Molecular and Cellular Biology and Public Health. In an interview with The News-Letter, she spoke about her research journey as well as her time at the ASF’s Innovators Symposium & Gala, which honors the 2024 Class of Astronaut Scholars.

Transforming clinical research: the need for inclusivity in clinical trials

By SHREYA TIWARI | September 12, 2024

The mistreatment and persistent exclusion of ethnic minorities, women, and other underrepresented groups from drug trials is a well-documented issue. In 2020, of the 32,000 individuals who participated in new American drug trials, key demographic groups were persistently underrepresented: only 8% were Black, 6% were Asian, and 11% were Hispanic.

MASSACHUSETTS GENERAL HOSPITAL AND DRAPER LABS / PUBLIC DOMAIN Mahto argues that the evidence against humans’ free will is only applicable to trivial tasks and not to important decisions. 

Science supports the existence of free will

By NEIL MAHTO | April 24, 2024

The idea of free will permeates nearly every institution. We reprimand those who commit crimes because we assume that they have a choice to act in that crime. We award honors for academic or athletic excellence assuming that the winner had some agency that allowed them to achieve their talent.

Just grateful: Saahith Potluri reflects on two years of research

By ZACHARY BAHAR | April 24, 2024

For the past two-and-a-half years, Potluri has worked in the Calabresi Lab which studies possible treatments for Multiple Sclerosis (MS). MS is an autoimmune disease of the central nervous system, and as it progresses, it can result in extreme fatigue, muscle weakness, loss of motor skills, loss of vision and numbness, among other symptoms. It is the most common disabling neurological disease for adults ages 20–40, and there is currently no known cure.

Breaking knowledge barriers: The need for open-access in science

By SHREYA TIWARI | April 22, 2024

The internet serves as a haven of scientific information, representing an era where the knowledge of anything we wish to know is available at our fingertips. Yet in many ways, accurate, firsthand accessibility to scientific research and comprehensibility of scientific knowledge is severely limited. A substantial overhaul is needed in the way that the general populace accesses scientific knowledge.
