Disrupted movement makes macrophages more lethal to tuberculosis bacteria
Macrophages—the front line of our immune system—protect us from infections. But in the case of the tuberculosis bacteria, this often goes wrong. The group of Annemarie Meijer from the Leiden Institute of Biology has now discovered that macrophage.....»»
Study suggests heavy snowfall and rain may contribute to some earthquakes
When scientists look for an earthquake's cause, their search often starts underground. As centuries of seismic studies have made clear, it's the collision of tectonic plates and the movement of subsurface faults and fissures that primarily trigger a.....»»
Marine bacteria team up to produce a vital vitamin
A German-American research team led by microbiologist Dr. Gerrit Wienhausen from the University of Oldenburg (Germany) has come an important step closer to a better understanding of highly complex interactions between marine microorganisms. The resea.....»»
Limited adaptability is making freshwater bacteria vulnerable to climate change
Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from Lake Zurich and other European lakes, researchers at the University of Zurich have uncovered specific evolut.....»»
Study underscores new strategies to fight drug-resistant bacteria
Several billion years ago, a genetic arms race began between bacteria and their viral killers. This seemingly eternal struggle continues today, with implications for diseases killing tens of thousands of people around the world each year......»»
Researchers show that slow-moving earthquakes are controlled by rock permeability
Earthquakes are the most dramatic and noteworthy results of tectonic plate movement. They are often destructive and deadly, or at the very least physically felt—they're literally groundbreaking geological events. However not all tectonic movement r.....»»
Study sheds light on cancer cell "tug-of-war"
Understanding how cancerous cells spread from a primary tumor is important for any number of reasons, including determining the aggressiveness of the disease itself. The movement of cells into the extracellular matrix (ECM) of neighboring tissue is a.....»»
What Australia can learn from Latin America when it comes to tackling violence against women
Fifty years ago, Australian feminist Anne Summers denounced "the ideology of sexism" governing over so many women's lives. Unfortunately, sexism is as lethal today as it was then......»»
How mantle movements shape Earth"s surface
The movement of tectonic plates shapes the rocky features of Earth's surface. Plates' convergence can form mountain ranges or ocean trenches, and their divergence can form oceanic ridges. But it's not just the plates themselves that influence Earth's.....»»
Novel triple drug combination effective against antibiotic-resistant bacteria
Scientists at the Ineos Oxford Institute (IOI) have found a new potential combination therapy to combat antimicrobial resistance (AMR) by targeting two key bacterial enzymes involved in resistance. The study, "The Triple Combination of Meropenem, Avi.....»»
Nano-drugs hitching a ride on bacteria could help treat pancreatic cancer
Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltra.....»»
Antimicrobial peptide from cows shows potential for treating hypervirulent bacteria
University of Central Florida College of Medicine researcher Renee Fleeman is on a mission to kill drug-resistant bacteria, and her latest study has identified a therapy that can penetrate the slime that such infections use to protect themselves from.....»»
Repair shop owner aims to start social impact movement in auto industry
In 2020, Dan Adam created a nonprofit group called Stranded Motorist Fund, which helps customers who can't afford expensive vehicle repairs......»»
25 years ago, The Matrix led a mini movement of sci-fi simulation thrillers
From The Matrix to eXistenZ to The Thirteenth Floor, 1999 was an unusually robust year for sci-fi movies that put the world inside a computer......»»
Study says El Nino, not climate change, was key driver of low rainfall that snarled Panama Canal
The climate phenomenon known as El Niño—and not climate change—was a key driver in low rainfall that disrupted shipping at the Panama Canal last year, scientists said Wednesday......»»
Researchers make a plastic that includes bacteria that can digest it
Bacterial spores strengthen the plastic, then revive to digest it in landfills. Enlarge (credit: Han Sol Kim) One reason plastic waste persists in the environment is because there's not much that can eat it. The chemical.....»»
How polyps of the moon jellyfish repel viral attacks on their microbiome
Bacteriophages, or phages for short, are viruses that infect bacteria and kill them through a lysis process. Phages can kill bacteria on or in a multicellular host organism, such as the polyp of the moon jellyfish. Phages specialize in specific bacte.....»»
Too many vehicles, slow reactions and reckless merging: New math model explains how traffic and bacteria move
What do the flow of cars on a highway and the movement of bacteria towards a food source have in common? In both cases, annoying traffic jams can form. Especially for cars, we might want to understand how to avoid them, but perhaps we've never though.....»»
Bacteria "nanowires" could help develop green electronics
Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity. In a study published recently in the journal Small, researchers revealed that protein nanowires—which were modified by adding a si.....»»
CRISPR is promising to tackle antimicrobial resistance, but bacteria can fight back
In his presentation "How to use CRISPR-Cas to combat AMR" at the ESCMID Global Congress, Assistant Prof. Ibrahim Bitar, Department of Microbiology, Faculty of Medicine and University Hospital in Plzen, Charles University in Prague, Plzen, Czech Repub.....»»
Study details a common bacterial defense against viral infection
One of the many secrets to bacteria's success is their ability to defend themselves from viruses, called phages, that infect bacteria and use their cellular machinery to make copies of themselves......»»
