As fall break looms ahead, let’s take a look at the recent scientific news. In the past week, laureates of the 2024 Nobel Prizes in Chemistry, Physics and Physiology or Medicine have been announced.
In the midst of the COVID-19 pandemic, there was increased hesitancy about vaccine effectiveness. One form of misinformation is deep fakes, which are becoming more prevalent and pose serious concerns for healthcare. Deep fakes are digitally altered videos or images that can use artificial intelligence to manipulate the words of popular figures, such as politicians or health experts, and can exacerbate global health issues like epidemics and pandemics.
The Johns Hopkins Institute for Clinical & Translational Research hosted the 14th annual Henrietta Lacks Memorial Lecture on Oct. 5 to honor the lasting legacy of Henrietta Lacks. Her cells, taken without her consent in 1951 became one of the most important tools in biomedical research, leading to countless breakthroughs in science. However, her story also brings to light the intersection of medical ethics, race and the treatment of marginalized communities in research.
As of October 2024, there are more than thirty FDA-approved gene therapies, spanning a diverse array of diseases such as certain cancers, hereditary disorders and chronic diseases. There are multiple ways that new genetic material can have therapeutic value. One of the most direct ways is through the replacement of a gene.
From Sept. 24 through Sept. 29, Hurricane Helene ravaged the Southeast, causing over 200 casualties and a staggering $250 billion in damages. Millions of Americans were left without power, and the devastation in states like Florida and Georgia was clear — thousands of buildings were flooded or destroyed, and the land the storm ripped through looked like a wasteland.
On Sept. 30th, Michael Bernstein, an associate professor of computer science at Stanford University, presented a talk at the Center for Language and Speech Processing about current efforts to improve behavioral simulations. His talk was titled “Generative Agents: Interactive Simulacra of Human Behavior“ and spotlighted the simulated town, Smallville, which his team worked on.
Here are some of the most groundbreaking developments in science this week, ranging from a novel approach to rejuvenating brain cells using CRISPR, new insights to understand the link between the TET2 gene and cancer, the global impact of species loss and the discovery of single-electron covalent bonds in carbon atoms.
The Laboratory for Computation Sensing and Robotics hosted Kevin Chen, an associate professor of electrical engineering and computer science at the Massachusetts Institute of Technology (MIT) on Wednesday, Sept. 25. In his talk, titled “Insect-scale Micro-Aerial-Robots Powered by Soft Artificial Muscles,” Chen explores the development of robots, the size of insects and their potential applications in our world.
This week’s Science News in Review is filled with new discoveries. From advances in therapeutics for schizophrenia treatment to fish that can taste with their legs, news this week focuses on groundbreaking innovations but also provides a reminder to stay cautious when reading scientific literature.
A coding project that aims to challenge undergraduates to come up with creative solutions and present them to a panel of specialized judges. HopHacks — a competition that brings students passionate about computer science and engineering together — embodies all this. The competition fosters broad-scale innovation through its many tracks, from the open-ended general track to more specialized tracks such as the Patient Safety Technology Challenge and the Philanthropy Track.
The field of artificial intelligence (AI) has seen significant advancements, and this week’s review showcases some of the most groundbreaking developments in AI foundation models and their interdisciplinary applications. These highlights include a breakthrough in neuromorphic hardware that could improve energy efficiency in AI, AI surpassing humans in predicting odor, Google’s progress in detecting AI-manipulated images and promising uses of large language models (LLMs) for debunking conspiracy theories.
On Monday, Sept. 16, the Institute for Global Tobacco Control at the Bloomberg School of Public Health hosted Thomas E. Novotny, professor emeritus of epidemiology and biostatistics at the San Diego State University School of Public Health. In a talk titled “Paddling Upstream to Prevent Tobacco Pollution,” Novotny discussed the type of waste produced from tobacco as well as to regulatory actions that may prevent the continuation of mass pollution from tobacco products.
Immunotherapy holds great promise for the future of cancer treatment. By harnessing a patient’s own immune system to target cancerous cells, cancer treatment can be tailored to an individual’s specific cancer type — allowing for more personalized treatment. One key avenue of current research involves studying cellular organization within tumors to understand the role of tumor-associated macrophages: white blood cells closely associated with the tumor microenvironment (TME) and are thought to support tumor growth and invasiveness.
On Thursday, September 12 the Department of Applied Mathematics and Statistics hosted Michael Mahoney of the Department of Statistics at UC Berkeley and the International Computer Science Institute. In his talk titled “Model Selection and Ensembling When There Are More Parameters Than Data,” Mahoney addressed why modern machine learning models work so well in practice, despite even mathematical theories being unable to fully explain them.
Adnan Munawar, an assistant research scientist at the Laboratory for Computational Sensing and Robotics (LCSR), shared his progress on the open-source Asynchronous Multi-Body Framework (AMBF) simulator used for several applications in surgical robotics on Sept. 11. The talk shed light on the use of reactive digital twins for surgical environments. His paper on AMBF was published in the Intelligent Robots and Systems (IROS) program.
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.
As the fall semester progresses, exciting discoveries continue to emerge across academia. This week’s highlights include a dye that renders mouse skin “transparent,“ a super precise nuclear-powered clock, new insights into cholesterol's role in heart disease and robots controlled by mushrooms.
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.
As the new academic year begins, let's dive into the latest breakthroughs and discoveries by scientists and engineers around the globe. This week’s highlights include promising developments in HIV vaccine research, insights into the human microbiome, legislative strides in AI and Deepfake regulation, and the discovery of new free-floating planetary bodies.
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.
