A longitudinal case study on an undergraduate researcher

I like the color purple. The number 22, the season of autumn and definitely cats over dogs. Everytime I try to explain what fuels my affections, I don’t have much to say: I am just drawn to them for no good reason that I can pinpoint.

Ringstad delivered a talk titled “Modulation of Behavior by Host-Microbe Interactions” to the Department of Biology.

How microbes influence worm neurobiology (and maybe ours, too)

On Thursday April 1, the Department of Biology hosted Niels Ringstad, professor in the Department of Cell Biology at the New York University Grossman School of Medicine. Ringstad delivered a talk titled “Modulation of Behavior by Host-Microbe Interactions” for the department’s seminar series, highlighting recent findings from his lab about the powerful effects of microbes on the behavior of the model organism Caenorhabditis elegans (C. elegans).

How former Hopkins student Colton El-Habr and Orbit make magic with vestibular stimulators

Colton El-Habr was a Whiting School of Engineering (WSE) student for a little over a year before dropping out in 2023 to commit full-time to Orbit Technologies (Orbit). Orbit is the neurotechnology startup El-Habr co-founded with Steven Pang, a former student at Georgetown University. In an interview with The News-Letter, El-Habr discussed his journey with the startup along with the details of Orbit’s technology.

The Science Policy and Diplomacy Group at Hopkins visited the Eisenhower Executive Office Building on a White House visit in 2024 to discuss policy initiatives with the Office of Science and Technology Policy.

Science Feature: Hopkins Science Policy and Diplomacy Group

In the wake of shifting political attitudes towards science, policymaking and advocacy have become critical in guiding the future of science. The Science Policy and Diplomacy Group at Hopkins is an entirely graduate-student-run group aiming to ensure that science and policy remain connected through advocacy, awareness and action.

Protestors gathered at the Lincoln Memorial to support funding for scientific research in light of recent cuts by the Trump administration.

Participants at Stand Up for Science Rally protest science research funding cuts in D.C.

On Friday, March 7, 2025, Stand Up for Science, a volunteer-based operation designed to protest perceived threats to scientific research and funding, gathered outside the Lincoln Memorial in Washington, D.C. The demonstration, which drew approximately 2,000 participants — including Hopkins students, lab groups and over 30 speakers from academia, hospitals and government — highlighted concerns over frozen research grants, the dismissal of government scientists and rollbacks on diversity, equity, and inclusion (DEI) initiatives.

Hopkins faculty and employees share how the termination of many USAID programs has impacted their work. 

Hopkins programs forced to close as Trump administration ends USAID grants

U.S. Secretary of State Marco Rubio announced on Monday, March 10, that the Trump administration had completed its six-week review of programs within the U.S. Agency for International Development (USAID) and will shutter 83% of the programs. The rest of the programs will be folded into the U.S. Department of State. The News-Letter spoke with several faculty and staff members at the School of Public Health whose work has been affected by the termination of USAID grants or reductions in funding from the National Institutes of Health (NIH).

EpiScalp uses brain network analysis to diagnose epilepsy with heightened accuracy. 

EpiScalp: Breakthrough innovation in epilepsy diagnosis

Epilepsy diagnosis is an imperfect science. Approximately 30% of patients are misdiagnosed after their first visit. Consequences of these misdiagnoses can be severe: Untreated epilepsy increases seizure frequency and can be fatal, but at the same time, false positive results are equally dangerous. Patients who receive false diagnoses of epilepsy can face unnecessary discomfort and receive unnecessary treatments with significant side effects.

Hopkins researchers recently developed a “reduced intensity haploidentical” bone marrow transplantation method to cure sickle cell disease.

Science news in review: March 10

With spring break quickly approaching, let’s take a look at some breaking scientific discoveries and news, from a new sickle cell disease cure to continued federal funding cuts.

Dr. Yuka Manabe and her team developed a tool to develop rapid diagnostic tests for many STDs, including HIV.  

Self-diagnostic tests for STDs: Diagnostic medicine in a post-COVID world

Despite the hardship the COVID-19 pandemic inflicted on many globally, it sparked immense progress in rapid testing for infectious disease: One could take a test quickly at home to determine whether they were infected, accelerating disease detection, treatment and recovery. Such innovation was partially championed by the Johns Hopkins University Center for Innovative Diagnostics for Infectious Diseases (JHCIDID).

AbdomenAtlas is an extensive dataset of 3D reconstructed and annotated abdominal CT scans that can be used to train AI technology on identifying cancer. 

AbdomenAtlas: an AI-based approach for early cancer diagnosis

A recent paper published by Johns Hopkins researchers in the Department of Computer Science details the development and use of AbdomenAtlas: an annotated public dataset containing abdominal CT scans from over tens of thousands of patients around the world. This new extensive dataset serves as the training ground for early-detection artificial intelligence programs, which have the potential to greatly improve the efficiency of cancer diagnosis and treatment.

Dang discusses the role and dynamics of the human microbiome. 

Trust your gut: The ins and outs of your gut microbiome

Imagine a bustling metropolis on a weekday morning: vehicles honking, people rushing to work, street vendors setting up shop and delivery trucks weaving through the chaos. Despite the apparent asynchrony, there is order to this chaos. If we shrink this scene down to the microscopic level, we zoom into the gut microbiome, a dynamic and complex ecosystem teeming with trillions of microorganisms checking their own to-do lists to keep us alive.

Death at sunset: How fungi create zombie flies

Carolyn Elya gave a talk titled, "The Last of (Fung)us: Mechanisms of Fruit Fly Behavioral Manipulation by the Killer Fungus Entomophthora muscae" on Feb. 13 as part of the Department of Biology Seminar Series. Elya, an an assistant professor in the Department of Molecular and Cellular Biology at Harvard University, leads a lab focused on elucidating how parasites manipulate the behavior of their hosts.

The individual riding an antigen-presenting complex (APC) highlights the two “selves” that exist inside the human body at the cellular and cognitive levels.

The two selves: the immune system and cognition

"Who are you?" This question, in its many variations, is almost inevitable in school applications, job interviews or introspective moments. We spend years, perhaps our entire lives, unraveling the intricacies of who we are. But there exists another sense of self, of which many are unaware, that stands by 24/7 to protect us. It resides within us, a quiet but essential arbiter of identity: our immune system.
