Singling out a bacterium from the crowd
Bacteria are nearly ubiquitous and have tremendous impacts on human and ecological health. And yet, they remain largely mysterious to us. Princeton MOL faculty Zemer Gitai, Britt Adamson and Ned Wingreen launched a joint effort to develop new tools t.....»»
Electroactive bacterium generates well-defined nanosized metal catalysts with remarkable water-splitting performance
A biological method that produces metal nanoclusters using the electroactive bacterium Geobacter sulfurreducens could provide a cheap and sustainable solution to high-performance catalyst synthesis for various applications such as water splitting......»»
Physics model could optimize basketball player positioning
A physics theory that's proven useful to predict the crowd behavior of molecules and fruit flies also seems to work in a very different context—a basketball court......»»
Smart microscopy works out where to take the picture
Is it possible to know exactly where to point a microscope in order to capture the precise moment a bacterium or a virus infects a cell? In order to take high resolution microscopic images of living biological material, you need to know exactly where.....»»
Soil bacteria as biocatalysts for producing pharmaceutical ingredients
Researchers from Bochum and Leipzig have successfully used a soil bacterium to specifically produce prodrugs. The key to this step was a detailed understanding of the metabolization of indole. The natural compound is first activated in microorganisms.....»»
Do masks work? It’s a question of physics, biology, and behavior
A recent review from a prominent scientific source has reignited the debate over masks. Enlarge / Asian woman with protective face mask using smartphone while commuting in the urban bridge in city against crowd of people (credit:.....»»
Stick to your lane: Hidden order in chaotic crowds
Have you ever wondered how pedestrians 'know' to fall into lanes when they are moving through a crowd, without the matter being discussed or even given conscious thought?.....»»
Signaling proteins shown to play key role in tuberculosis biology
A set of 10 signaling proteins found in the microbe that causes tuberculosis (TB) play a far larger role in regulating the bacterium's growth, development and behavior than previously thought, according to recent research. The study was led by UW Sch.....»»
Researchers decode how bacterium causing 30% of out-of-hospital pneumonia obtains lipids to survive
A research team including the involvement of the UAB has identified the P116 protein, by which the bacterium Mycoplasma pneumoniae obtains cholesterol and other lipids needed to survive. The study, led by the IBMB-CSIC and the Buchmann Institute in G.....»»
Scientists reveal flaws in tuberculosis bacterium by studying ferredoxins
Small proteins called ferredoxins play a pivotal role in the main metabolic pathways, the series of chemical reactions occurring within a cell......»»

Mac mini with M2 review: More power for less money
The second Apple Silicon Mac mini has arrived two years after the line first migrated, and with the M2 processor, it remains the best computer for switchers, and for the computer as appliance crowd.The 2023 Mac mini M2The usual refrain for the Mac mi.....»»
Thermal fluctuations and oscillation modes found to determine the uptake of bacteria in cells
How and with what effort does a bacterium—or a virus—enter a cell and cause an infection? Researchers from Freiburg have now made an important contribution to answering this question......»»
Plasmids and the spread of antibiotic resistance genes
Though the harnessing of antibiotics is one of the most significant human innovations, their efficacy is continuously eroded by the craftiness of their microbial targets. Once a single bacterium mutates to become resistant to antibiotics, it can tran.....»»
Genetically engineered bacterium enables biosynthesis of melanin nanoparticles
Photothermal therapy (PTT) has attracted considerable attention for the treatment of tumors because it is minimally invasive and has spatiotemporal selectivity......»»

Chinese startup"s US$140,000 car can fly over traffic jams
The crowd of hundreds roared in Mandarin as the gull-winged two-seater aircraft rose and hovered roughly 30 meters above their heads, before smoothly lowering back down to earth. "Make us Chinese proud in Dubai!" several of the more enthusiastic shou.....»»
Researchers analyze performance of bacterium in combating coffee rust
A new study has analyzed the potential of a bacterium for biological control of the fungus Hemileia vastatrix, which causes coffee rust, a major challenge for Brazilian coffee growers. An article on the study is published in the journal BMC Microbiol.....»»
Punk hairstyles and pirouettes: There"s more to spiders than people think
Spider scientists are an optimistic crowd. Perhaps it's just that we see things from a different angle to arachnophobes. If you don't believe me, look up Theridion grallator. Researchers from my field call this Hawaiian species the happy-face spider.....»»
Moonlighting protein makes a hospital germ harmful
The Pseudomonas aeruginosa bacterium is a widespread and dangerous hospital germ. It infects the respiratory tract and lungs and possesses natural resistance to numerous antibiotics. There is an ongoing search for so-called pathoblockers to be able t.....»»
