Lena Ting and her team at Emory University set out to understand how aging and Parkinson’s disease affect brain and muscle responses as people try to regain balance. In previous experiments, researchers worked by suddenly destabilizing young people, essentially pulling the rug out from under their feet. This triggered a rapid and automatic response involving the brainstem and muscles. As the balance challenge became more acute, a second wave of activity followed, involving both the brain and muscles. In the latest research published in e-neurothe research team studied older adults with and without Parkinson’s disease. They found that these people…

Scientists have uncovered the hidden cause of radiation sickness by photographing atoms ‘walking around’ before exploding. process: This research focuses on electron transfer-mediated decay (ETMD), a radiation-driven process that breaks apart loosely bonded atoms. This mechanism is particularly important because it can generate highly reactive particles in water and is an important factor in the effects of radiation on biological systems. experiment: Scientists tracked this process in amazing detail using special reaction microscopy combined with advanced theoretical simulations. This allows us to precisely track how damping evolves over time in carefully controlled model systems. What they discovered: The team effectively…

Thousands of years ago, the Beast of Burden helped make humanity what it is today. When farmers first started planting their roots, they planted and tended their crops by hand. They could use the power of their oxen to drag plows across the fields before sowing, increasing soil fertility and eliminating weeds. Today, that task is made even easier by huge machines that scrape the landscape. But thousands of years of cultivation came at a cost. Although tillage releases nutrients in the short term, it reduces soil fertility in the long term, requiring farmers to load their fields with synthetic…

March is National Colorectal Cancer Awareness Month, and a new poll by the Physicians Committee for Responsible Medicine and the Morning Exam highlights major knowledge gaps. Almost half of Americans are unaware that eating processed meat is associated with an increased risk of colorectal cancer. The survey, conducted among 2,202 U.S. adults from February 9 to 11, 2026, also found that attitudes can quickly change opinions. After learning of this link, about two-thirds of respondents said they supported warning labels on processed meat products to highlight cancer risks. Rising incidence of colon cancer among young people “Given that colorectal cancer…

TThe fate of environmentalists is to spend their lives trying not to be vindicated. What we fear is justification. But there is one threat that bothers me more than the others. It is the collapse of the global food system. It is impossible to predict what the immediate trigger will be. But a war with Iran is exactly the kind of event it would be.I have been arguing for some time, based on years of scientific data, that this risk exists and that governments are woefully unprepared for it. In 2023, I submitted a parliamentary inquiry into environmental change and…

Swedish fathers are less likely to receive a psychiatric diagnosis during their partner’s pregnancy or in the months immediately following the birth of their child. However, this pattern reverses over time. New research published in JAMA network open They report that diagnoses of depression and stress-related symptoms increase approximately 1 year after childbirth. The research was led by scientists from Sweden’s Karolinska Institutet and China’s Sichuan University. “The transition to fatherhood is often accompanied by both positive experiences and a variety of new stresses,” says Jin Zhou, a doctoral student at Karolinska Institutet’s Institute of Environmental Medicine and co-lead author…

Being in the oncologist’s office is always stressful. It appears at the time of diagnosis, increases at each stage of treatment, and often does not resolve even after treatment has officially ended. It involves making treatment decisions, waiting for test results, fear of recurrence, and changes in daily functioning. Research shows that chronic stress can trigger biological processes that accelerate disease progression and weaken the body’s defenses. This perspective is presented in a systematic review prepared by researchers from the Wroclaw Medical University and published in 2026. International Journal of Molecular Science. The authors analyzed data on four cancers: breast…

Cornell University researchers and collaborators have developed an entirely tiny neural implant. Despite its size, the device can wirelessly transmit brain activity data from live animals for more than a year. Progress reported in nature electronicsshows that microelectronic systems can operate on very small scales. This could open the door to new approaches in brain monitoring, biointegrated sensors, and other medical and technological applications. What is a MOTE device This device is known as a microscale optoelectronic tetherless electrode (MOTE). Its development was led by Alyosha Molnar, a professor in the Department of Electrical and Computer Engineering at Cornell University,…

iXCells Biotechnologies (“iXCells”), a leading provider of human cell-based solutions and custom iPSC services, today announced that it has entered into an international collaboration with Rosebud Biosciences (“Rosebud”), Kantify, and Incite to assess off-target chemotherapy toxicity in patient-specific organoids. Building on recent partnerships with iXCells and Rosebud and funding from Incite, this project will initially focus on predicting toxicity in heart, liver and kidney tissue models to develop personalized multi-organ toxicity profiles for novel chemotherapy. During this partnership, iXCells will reprogram peripheral blood mononuclear cells (PBMCs) isolated from the blood of patients with liposarcoma, a rare malignant cancer derived from…

Optibrium, a leading developer of software and AI solutions for molecular design, today announced the new QuanSA™ plugin for PyMOL. It provides an intuitive graphical user interface (GUI) for the ligand-based binding affinity prediction methods that are part of the company’s BioPharmics 3D molecular modeling platform. The new interface gives chemists easier access to accurate affinity predictions to guide the design of potent compounds, reducing the synthesis and testing burden of lead optimization. An example of the visual output provided by the new QuanSA PyMOL plugin. m32 is approximately 50 times stronger than the structurally similar m01, despite having an…
