The most critical superbug strains (as of 2024)

More than 39 million people are expected to die from antimicrobial resistance by 2050

In 2024, researchers published an incredibly detailed study aimed at predicting the real-world impact of antimicrobial resistance over the next 25 years. The key findings were clear: the superbug crisis is poised to get much worse and needs to be addressed. This article offers a clear, concise overview of the study, which was published in The Lancet.

Superbugs are bacteria and pathogens that rapidly evolve defenses against medication

Superbugs, or antibiotic-resistant bacteria, infect millions and pose a threat to global health. Developing new antibiotics is costly, offers limited profits, and struggles to outpace bacteria’s rapid evolution.

Drug-resistant infections worldwide have increased by about 65% since 2000

Since 1990, antibiotic resistance has claimed at least one million lives annually and is projected to account for 39 million deaths between now and 2050 if current trends continue. The expanded use of antibiotics, particularly in agriculture, combined with a slowing pipeline of new drugs has led to the crisis.

19 fungal pathogens are of key concern to world health officials

In 2022, this global health body issued its first-ever list of top fungal threats to human health. It said fungal threats are spreading and occurring more frequently. The WHO’s list included 19 fungal pathogens to watch, and said that the most dangerous ones to public health are Cryptococcus neoformans, Aspergillus fumigatus, Candida albicans, and Candida auris. There are only a handful of classes of medication currently available to combat fungal pathogens, with few others in the pipeline even though antimicrobial resistance is growing.

Drug-resistant staph infection is one of the deadliest superbugs

Methicillin-resistant Staphylococcus aureus (MRSA)—the superbug version of staph infection—is responsible for more deaths than any other superbug, killing more than 120,000 people globally each year. The bug is leading cause of hospital infections, and is harmless on the skin but causes severe symptoms once inside the body.

Tips for reducing the risk of antimicrobial resistance

Antimicrobial resistance is bad news. But there are lots of things you can do to both protect yourself from superbugs and help keep the problem of antimicrobial resistance from getting worse. This page from the CDC offers clear, straightforward guidelines that can help keep you—and your loved ones—healthy.

The new antibiotic killing drug-resistant bacteria

A new class of antibiotics had not been discovered in more than 50 years—until late 2023, when MIT researchers announced a new antibiotic called Zosurabalpin. In animal testing, Zosurabalpin was able to treat at least one type of superbug. While the drug still needs to go through clinical trials, it is a significant advance at a time when new antibiotics are in great demand.

Candida auris spreads easily in healthcare facilities and causes high death rates

This fungus has spread rapidly in healthcare settings since the first US case was reported in 2016, and it has grown increasingly resistant to echinocandins, the antifungal medicine most commonly used to treat it. Often, it’s resistant to multiple antifungal drugs, contributing to its high death toll. It can most readily infect those with invasive medical devices like intravenous catheters and those with frequent or long-duration stays in healthcare facilities.

COVID accelerated antibiotic resistance

The COVID-19 pandemic was caused by a virus, and viruses can’t be treated with antibiotics. But recent research finds that COVID patients were given a tremendous amount of antibiotics, contributing to the problem of antibiotic-resistant bacteria. Why? This NPR feature sheds light on an unexpected side effect of the pandemic.

Advanced drugs are closing in on cancer's deadliest mutations

The protein KRAS, mutated in many cancers, was deemed ‘undruggable’. Now scientists are hoping to save lives with a batch of new compounds that target it.

Pneumonia was once a leading killer before penicillin treatments

In the early 20th century, pneumonia was a top cause of death worldwide, often fatal without effective treatment. Penicillin turned a once deadly infection into one of the most treatable bacterial diseases.

Examining the potential of the emerging field of insect-based bioremediation

Also known as entomoremediation, the novel approach uses larvae and adult insects, including their gut microbiomes and associated enzymes, to extract or degrade pollutants. As of 2025, research has shown that black soldier flies can degrade a wide range of antibiotics, highlighting their potential for bioremediating antibiotic-contaminated organic waste.

As of February 2025, there are more than 150 clinical trials using CRISPR technology

The clinical trials are designed to determine whether experimental CRISPR-related therapies are safe and effective. The majority of trials involve treatments for blood disorders, including beta thalassemia.

10 locally acquired malaria cases were reported in the US in 2023—a surprise

The cases, reported in Florida, Texas, Maryland, and Arkansas, broke a 20-year streak since there had been no reported locally acquired mosquito-transmitted malaria in the country since 2003, when there was a case in Florida.

Read a technical review of extremophile categories, including the habitats of each

Acidophiles can survive in environments with acidity greater than that of the human stomach, and some radiophiles can live in places with radiation exposure hundreds of times higher than what is lethal to humans. Piezophiles—formerly known as barophiles—have been found in the Mariana Trench, where pressures are over 1,000 times larger than those on Earth's surface.

See this ranking of the top 10 medical shows on television

The Hollywood Reporter created this 2025 ranking of 10 television shows from around the world that focus on medicine. Candidates included "Grey's Anatomy," "The Pitt," "New Amsterdam," "ER," and more. The publication warns that its ranking is a living document that may change with time—and that its explanations include show spoilers.

The flu vaccine has evolved alongside discoveries of new virus strains

After influenza B was identified in 1940, researchers created a two-strain vaccine by 1942. The WHO later built a global surveillance system to track mutations, enabling vaccines to be updated annually to target the strains most likely to circulate.

The US FDA issued a 2025 warning about BPC-157 and other popular peptides

BPC-157, which mimics a naturally occurring gut peptide involved in soft tissue repair, has been marketed for various regenerative properties. But the FDA warned in July 2025 that it doesn't have enough data to assess its safety in humans and that such products may also pose risks related to contamination.
