Severe disease related to COVID-19 infection may be linked to the absence of a single sugar molecule on antibodies in patient sera samples. Continue reading Severe COVID-19 Disease Potentially Linked to a Single Missing Sugar in Antibodies
by Melis Tekantfigures by Aparna Nathan The pandemic caused by the novel coronavirus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has arguably been the single most devastating global crisis in recent history. As of December 2020, the virus claimed the lives of 1.7 million people, and healthcare systems around the world have been stretched to their limits. Notably, the U.S. has been exceptionally hard hit, … Continue reading Optimal Strategy for a COVID-19 Vaccine Roll-out
Researchers have developed a fast, cheap, and quantitative antibody test to allow us to understand how COVID-19 affects our immune response. Continue reading Fighting COVID-19 with a Faster, Cheaper, and Quantitative Antibody Test
Current polio vaccines have been successful in nearly eradicating polio in the world. Unfortunately, there have been emerging cases of polio in recent years. To combat this, scientists have designed a new oral poliovirus vaccine that could result in a new and safer polio vaccine. Continue reading Redesigning the polio vaccine – Lessons from evolution
Nerve agents are toxic chemicals that disrupt signals in the nervous system. They can be absorbed easily through skin contact or by breathing. Exposure to nerve agents interferes with nerve cell signaling and prevents muscles from relaxing, quickly leading to muscle paralysis and eventually death by asphyxiation or cardiac arrest. Treatment is possible but must be administered within minutes of exposure. No long-term vaccine or … Continue reading Nano-antidote provides long-term protection against nerve agents
Infectious diseases — including HIV, tuberculosis, and malaria — are a leading cause of death worldwide, particularly in low income countries and among young children. A new study found that the vaccines aimed to prevent many of the world’s most deadly diseases may not be developed any time soon. The study, funded by the Gates Foundation and the Swiss Agency for Development and Cooperation, focused on 538 … Continue reading Vaccines for World’s Most Deadly Infectious Diseases Unlikely
by Catherine Weiner figures by Rebecca Senft Every winter, as we avoid the sneezing stranger on the sidewalk and the coughing coworker in the coffee room, the same thought races through our heads: “I hope it’s not the flu.” This year, the United States has been hit with a devastating flu season. As of March 17th, the Centers for Disease Control and Prevention (CDC) recorded … Continue reading Hit Me with the Flu Shot: Why you need the flu shot every year
It’s the middle of February and flu season is in full swing. Perhaps you’ve already experienced the body aches, fever, and fatigue that signal the influenza virus. However, there is a chance that these same symptoms were not caused by the flu. A family of viruses called adenovirus is also making the rounds and resembles the flu. The adenovirus kills significantly fewer people than the … Continue reading Achoo! Is Adenovirus making you sick this winter?
by Fernanda Ferreira figures by Brad Wierbowski Every day 140 Americans die from an opioid overdose. To confront the crisis, not only must opioid addiction treatment become more readily available, but new and improved forms of treatment must also be developed. Dr. Carl Alving, whose life work has been to develop an HIV vaccine, never planned on investigating novel systems for treating opioid addiction. But … Continue reading Can We Treat Heroin Addiction and HIV with a Single Vaccine?
