Deconstructing the infectious machinery of SARS-CoV-2
Scientists have published a comprehensive study that -- alongside other recent, complementary studies of coronavirus proteins and genetics -- represents the first step toward developing treatments for COVID-19......»»
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......»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
Engineers muffle invading pathogens with a "molecular mask"
Vaccines remain the gold standard of protection against dangerous pathogens, but take considerable time and vast resources to develop. Rapidly mutating viruses such as SARS-CoV-2 can blunt their effectiveness and even render them obsolete......»»
Arboviruses, mosquitoes and potential hosts tracked in real time in São Paulo city
The technology used to sequence SARS-CoV-2 at record speed early in the COVID-19 pandemic has been successfully tested as a technique to monitor arboviruses and diseases transmitted mainly by mosquitoes......»»

Single-crop farming has potential to harm bees, study finds
Mass-blooming, monoculture crop fields don't seem to reduce the microbial diversity in a bee's gut, University of Oregon researchers have found in a study of sunflower farms, but they do amplify the spread of infectious parasites......»»
Scientists report that buffer and pH strongly affect the phase separation of SARS-CoV-2 N protein
In a new paper published in Molecular Biology of the Cell, the Allain lab (IBC) reported that the phase separation of the SARS-CoV-2 N protein strongly depends on the chosen buffer and pH. For example, the protonation of a single histidine side chain.....»»
Must mRNA be cloaked in a lipid coat to serve as a vaccine?
The Uchida Laboratory of Innovation Center of NanoMedicine has demonstrated that intradermal administration of mRNA alone (naked mRNA) without protection by nanoparticles induced robust vaccination against SARS CoV-2, a virus causing COVID-19, in mic.....»»
Nanoparticles target multiple COVID variants through the twist in the spike protein
Teardrop-shaped particles designed to inactivate multiple strains of the SARS-CoV-2 virus could one day complement existing treatments for COVID-19, according to a new study led by researchers at the University of Michigan and Jiangnan University in.....»»
New bioengineered protein design shows promise in fighting COVID-19
In the wake of the COVID-19 pandemic, scientists have been racing to develop effective treatments and preventatives against the virus. A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus re.....»»
The next pandemic? It"s already here for Earth"s wildlife, says biologist
I am a conservation biologist who studies emerging infectious diseases. When people ask me what I think the next pandemic will be I often say that we are in the midst of one—it's just afflicting a great many species more than ours......»»
New biology unveiled for fundamental cellular machinery
Cellular communication relies on receptor molecules on the cell surface. The periodic uptake and sorting of these receptors, critical for their degradation or recycling, are governed by an elaborate machinery prominently featuring the Commander compl.....»»
How the SARS-CoV-2 virus acquires its spherical shape
For centuries, coronaviruses have triggered health crises and economic challenges, with SARS-CoV-2, the coronavirus that spreads COVID-19, being a recent example. One small protein in SARS-CoV-2, the membrane protein, or M protein, is the most abunda.....»»
Temperature, humidity may drive future transmission of parasitic worm infections
As climate changes, temperature isn't the only factor to influence the spread of infectious diseases. Humidity plays a role, too, according to new research published this week (Feb. 25) in Ecology Letters......»»
Worker killed in accident at Italian Stellantis plant
The victim, a maintenance worker for a contracto, died while carrying out work on a piece of machinery......»»
Toxoplasmosis: Researchers identify protein that evolved alongside infection machinery
Toxoplasmosis is an infectious disease found worldwide, caused by the single-celled parasite Toxoplasma gondii. In humans, infection poses a particular risk to pregnant women, as it can lead to birth defects. Like the closely related malaria pathogen.....»»
Can you sanitize the inside of your nose to prevent COVID? Nope, FDA says.
There are a lot of COVID nasal sprays for sale, but little data to show they work. Enlarge (credit: Nozin.com) More than four years after SARS-CoV-2 made its global debut, the US Food and Drug Administration is still wor.....»»
Testing shows some bacteria could survive under Mars conditions
An international team of radiation specialists, biologists and infectious disease experts has found four types of bacteria that are capable of surviving exposure to the hostile Mars environment. In their study, published in the journal Astrobiology,.....»»
An infectious gibbon ape leukemia virus found to be colonizing a rodent"s genome in New Guinea
A research team has caught a glimpse of a rare case of retrovirus integration. Retroviruses are viruses that multiply by incorporating their genes into the genome of a host cell. If the infected cell is a germ cell, the retrovirus can then be passed.....»»
