Myocardial infarction may be an infectious disease

news.ycombinator.com Unknown 2025-09-24 17:55:42

According to the recently published research, an infection may trigger myocardial infarction. Using a range of advanced methodologies, the research found that, in coronary artery disease, atherosclerotic plaques containing cholesterol may harbour a gelatinous, asymptomatic biofilm formed by bacteria over years or even decades. Dormant bacteria within the biofilm remain shielded from both the patient’s immune system and antibiotics because they cannot penetrate the biofilm matrix. A viral infect

Microbes are known for their remarkable survival abilities. And now, scientists have discovered another remarkable trait: Turning cement into an electricity storage device. In a study published September 9 in Cell Reports Physical Science, researchers at Aarhus University in Denmark describe how they seeded a bacteria called Shewanella oneidensis into cement. These particular bacteria are known to be good at transferring electrons across surfaces, and the researchers wondered if they could act

New Bacteria Discovered in Flies Could Sicken Humans

A new species of bacteria has come to light in Brazil. It’s genetically similar to two other disease-causing bacteria from the Andes, which are known to infect humans through sand fly bites. According to a study published this summer in the journal Acta Tropica, researchers have discovered a new bacteria species in phlebotomine insects (sand flies) in the Amazon National Park in Brazil’s state of Pará. Its DNA is similar to that of two Andean bacteria in Peru, Bartonella bacilliformis and Barto

Some Heart Attacks Might Be Triggered by Germs

gizmodo.com Ed Cara 2025-10-05 01:30:27

Germs might be even worse for us than we thought. New research suggests that certain infections could be a contributing factor to heart attacks. Scientists in Finland and the UK conducted the study, which examined arterial plaques taken from people who died from heart disease and others. They found these plaques often contained a dormant layer of bacterial biofilm; they also found evidence that bacteria released from this biofilm can then trigger heart attacks. Though not yet definitive, the st

Millions of Americans heading to the shore for the holiday weekend are encountering warning signs instead of waves. From New England to California, public health officials have flagged dozens of beaches for high levels of fecal bacteria, urging swimmers to stay out of the water. The advisories, affecting coastal stretches in Massachusetts, New York, California and even Hawaii, cite unsafe concentrations of E. coli and enterococci, bacteria linked to sewage and storm runoff.

These Newly Discovered Cells Breathe in Two Ways

The team members went through a process of incrementally determining what elements and molecules the bacterial strain could grow on. They already knew it could use oxygen, so they tested other combinations in the lab. When oxygen was absent, RSW1 could process hydrogen gas and elemental sulfur—chemicals it would find spewing from a volcanic vent—and create hydrogen sulfide as a product. Yet while the cells were technically alive in this state, they didn’t grow or replicate. They were making a sm

At Least 2 People Died of ‘Flesh-Eating’ Bacteria After Eating Tainted Oysters

“Flesh-eating” bacteria are continuing to claim lives this summer. Louisiana health officials reported this week that two more people have died from Vibrio infections this month, potentially caused by eating tainted oysters. The Louisiana Department of Health announced the latest deaths during a meeting of the Louisiana Oyster Task Force held Tuesday. Both deaths are linked to oysters harvested in the state, but the oysters were eaten at separate restaurants in Louisiana and Florida. Louisiana

Climate Change Is Bringing Legionnaire’s Disease to a Town Near You

This story originally appeared on Vox and is part of the Climate Desk collaboration. Air conditioners have been working overtime this hot summer, from those tiny window units to the massive AC towers that serve the tightly packed apartment buildings in major cities. And while they bring the relief of cool air, these contraptions also create the conditions for dangerous bacteria to multiply and spread.

A bacterial infection that can cause “flesh-eating” disease is becoming a bigger problem in the U.S.—and climate change is at least partly to blame. Several states along the Gulf Coast and Eastern Seaboard have already reported a higher than usual tally of Vibrio vulnificus cases and deaths this summer. Last week, for instance, the Louisiana Department of Health issued a warning to residents over increased reports of V. vulnificus. Experts argue that milder winters and hotter summers are allowi

Newly Discovered Gut ‘Sense’ Could Change How We Think About Hunger and Health

There really is something to the concept of having a gut feeling. New research out today suggests our bodies can directly sense and communicate with the many bacteria lining our digestive tract. Scientists at Duke University led the study, published Wednesday in Nature. They found that nerve cells can respond in real time to bacterial signals from the gut—including signals that tell us to curb our appetite. The findings suggest the relationship we have with our microbial neighbors is even more

Their work could lead to the development of sensors for agricultural and other applications, which could be monitored by drones or satellites. The resea
