Spinal Bone Density May Predict Cognitive Decline, New Study Finds

A new study published in Radiology indicates that lower bone density in the spine is associated with faster cognitive decline and changes in brain white matter. The research, led by Johns Hopkins University, used AI to analyze chest CT scans of 715 adults, finding that those with lower bone density experienced more rapid brain deterioration over five years. The link was particularly strong for individuals with type 2 diabetes. While the study does not prove causation, it suggests bone density could serve as an early marker for brain health risks.

Study Finds AI Drafts Less Formal Work Emails When Prompts Use Female-Associated Language

Research from Johns Hopkins University reveals that major AI models generate less formal and complex professional writing when prompts include linguistic patterns commonly associated with women. The study found that this bias persists across OpenAI, Meta, Google, and Mistral models, potentially disadvantaging women in workplace communications.

ICE Detains Johns Hopkins Researcher Over Visa Overstay

Federal immigration agents detained Fatima Ameaka, a Johns Hopkins researcher, at Baltimore-Washington International Thurgood Marshall Airport on allegations she overstayed her U.S. visa, which was valid until June 13, 2024 after she entered on June 27, 2023. She remains in ICE custody awaiting removal proceedings; Hopkins says it is assisting with legal representation and monitoring her health, amid concern from colleagues and supporters online and political figures about her treatment and access to medications.

Measles in the U.S. climbs to a 35-year high with months left in 2026

Data from Johns Hopkins University shows the United States has recorded 2,295 measles cases in 2026 so far—the most in a year since 1991—signaling a resurgence tied to outbreaks across multiple states and lower vaccination rates, with more than five months remaining in the year.

Why We Struggle to Judge Knot Strength Accurately

A study by Johns Hopkins University researchers reveals that people struggle to judge the strength of knots, highlighting a potential "blind spot" in our physical reasoning. Despite knots being a common part of daily life, participants in the study failed to accurately assess knot strength, even with visual aids. The research suggests that understanding soft objects like string or rope may be more challenging than solid ones, and that expertise in knot-tying, such as that of sailors or mountaineers, might improve judgment.

The Knot Conundrum: Why We Misjudge Knot Strength

A study by Johns Hopkins University reveals that people struggle to visually assess the strength of knots, despite their familiarity with them. Participants consistently failed to identify the strongest knot among similar ones, even when shown videos or diagrams. This suggests a blind spot in our intuitive physical reasoning, as we cannot easily discern the internal structure of non-rigid objects like knots. The research highlights the complexity of understanding knot strength and suggests that expertise, such as that of sailors, might improve performance.

The Knot Conundrum: Why We Misjudge Knot Strength

A study by Johns Hopkins University reveals that despite our familiarity with knots, most people struggle to visually determine the strength of different knots. Participants consistently failed to identify the strongest knot, even when shown videos or diagrams. This suggests a blind spot in our physical reasoning, as we cannot intuitively assess the internal structure of non-rigid objects like knots. The research highlights the complexity of intuitive physics and our limitations in understanding the physical properties of certain objects.

AI Outpaces Supercomputers in Solving Engineering Challenges

Researchers at Johns Hopkins University have developed a new AI framework called DIMON that can solve complex engineering problems, such as modeling car crashes or predicting heart arrhythmias, much faster than traditional methods. This AI can handle partial differential equations across various shapes without recalculating grids, significantly speeding up simulations and optimizing designs. The technology promises to revolutionize fields like engineering and medicine by enabling personal computers to perform tasks that typically require supercomputers.

"The Psychedelic Evangelist: Exploring the Power of Mind-Altering Substances"

Roland Griffiths, a renowned psychedelics researcher at Johns Hopkins University, conducted rigorous studies on the potential therapeutic effects of psilocybin, found in magic mushrooms, for treating anxiety, depression, addiction, and the fear of death. While known for his analytical approach and agnostic beliefs, Griffiths also saw psychedelics as crucial for humanity's survival and admitted to using them himself. However, a former colleague has criticized his research methods, likening them to a "new-age retreat center," raising questions about the influence of psychedelic advocates on the field and the potential mistakes made in focusing on the mystical aspects of psychedelics.

"Debunked: Interstellar Alien Signal Traced Back to Local Truck Vibrations"

A Johns Hopkins University-led team has found that the sound waves previously thought to be from a 2014 meteor fireball near Papua New Guinea were likely vibrations from a passing truck, casting doubt on the belief that materials recovered from the ocean last year were of alien origin. The team's research suggests that the materials are ordinary meteorites or particles produced from other meteorites hitting Earth's surface mixed with terrestrial contamination, and they identified a more likely location for the meteor more than 100 miles from the initially investigated area.

Unveiling the Universe's History: New Maps and Measurements from Earth and Beyond

Scientists at Johns Hopkins University have used the Cosmology Large Angular Scale Surveyor (CLASS) telescopes to map 75% of the sky over Earth and study the polarization of the cosmic microwave background (CMB), a remnant light from the universe's early history. By filtering out interference from the Milky Way, the team aims to understand the universe's initial conditions and the evolution of matter, including the formation of stars and galaxies. Their research, published in The Astrophysical Journal, provides essential insights into the universe's history and sets a new standard for ground-based polarization measurements.

Preventing Heart Disease in Women: Expert Advice and Support

Dr. Sabra Lewsey, a cardiologist at Johns Hopkins University, outlined key steps for women to prevent heart disease, the leading cause of death for women in the U.S. She emphasized the importance of knowing and monitoring key health numbers, paying attention to heart rhythm, understanding family history, and collaborating with healthcare providers. By staying proactive about health measurements, leading a healthy lifestyle, and ensuring doctors communicate about heart health, women can significantly reduce their risk of developing serious heart diseases.

"Campus Chaos: Johns Hopkins Entangled in Israel-Gaza Conflict"

Johns Hopkins University, like many other colleges, is navigating a war of narratives surrounding the Israel-Palestine conflict on its campus. After issuing a response to the Hamas attack, the university faced demands from its graduate student workers union to call for a ceasefire in Gaza. The conflict has sparked competing acts of protest, with accusations of Islamophobia and antisemitism. Colleges are struggling to play the roles of nonpartisans and moderators, attempting to acknowledge multiple perspectives while ensuring the safety and inclusivity of their communities. The university has held public discussions and virtual classes to encourage discourse, but the challenge lies in finding a balance between supporting students and avoiding performative statements.

"Unveiling the Secrets of the Universe: Data Science Revolutionizes Space Exploration"

Researchers at Johns Hopkins University have developed a data science method to match astronomical objects across different surveys, allowing for a deeper understanding of the cosmos. By assigning a "score" to pairs of observations from different surveys, the researchers were able to quickly and effectively match objects between 100 different catalogs. This method helps scientists extract more knowledge from the vast amount of data collected by telescopes, contributing to the building of theories about the universe. The team's code is publicly available, and their research was published in The Astronomical Journal.
