  • One vaccine injection could carry many doses

    MIT engineers have invented a new 3-D fabrication method that can generate a novel type of drug-carrying particle that could allow multiple doses of a drug or vaccine to be delivered over an extended time period with just one injection.

    The new microparticles resemble tiny coffee cups that can be filled with a drug or vaccine and then sealed with a lid. The particles are made of a biocompatible, FDA-approved polymer that can be designed to degrade at specific times, spilling out the contents of the “cup.”

  • New climate risk classification created to account for potential 'existential' threats

    A new study evaluating models of future climate scenarios has led to the creation of the new risk categories “catastrophic” and “unknown” to characterize the range of threats posed by rapid global warming. Researchers propose that unknown risks imply existential threats to the survival of humanity.

    These categories describe two low-probability but statistically significant scenarios that could play out by century’s end, in a new study by Veerabhadran Ramanathan, a distinguished professor of climate and atmospheric sciences at Scripps Institution of Oceanography at the University of California San Diego, and his former Scripps graduate student Yangyang Xu, now an assistant professor at Texas A&M University.

  • Study Adds to Evidence That Racial and Economic Factors Affect Surgical Pain Management

    A “look back” analysis of more than 600 major colorectal surgeries using a “checklist” tool has added further evidence that racial and socioeconomic disparities may occur during many specific stages of surgical care, particularly in pain management.

  • NASA's One-Year Mission Investigates How Space Affects Astronauts' Functional Performance

    Adapting to the microgravity environment of space changes the way your brain interprets sensory signals, decreases muscle strength and alters cardiovascular function. Astronauts will need to overcome these changes to perform critical mission tasks on a journey to Mars. Simple tasks on Earth such as exiting a vehicle becomes more crucial when stepping foot in an unfamiliar world. Maintaining balance control will be key to a successful mission.

  • Standing too much at work can double your risk of heart disease

    There's been a lot of interest in the harmful effects of prolonged sitting at work, from academics and the public alike. The attention being paid to sitting – or rather, not sitting – while on the job stems from the scientifically validated message that being sedentary in general, both indoors and outdoors, is bad for your health.

    However, comparatively little attention has been devoted to the harmful effects of prolonged standing at work, despite past studies linking it to chronic back pain and musculoskeletal disorders (MSDs) in the lower limbs.

  • Low-Level Radiation Less Harmful to Health Than Other Lifestyle Risks

    Human populations have always been exposed to ionizing radiation, and more so in modern life due to its use in medicine, industry and the armed forces. Whilst the risks to human health from medium and high-level radiation are relatively well-understood, the risks at lower levels are less clear.  Mixed messages about the safety of low doses of radiation from different sources have created confusion for the public and for policy makers.
