Apple iPhone 14 review: the familiar iPhone I can’t help but love
Tthe iPhone 14 may be 'just another iPhone,' but it doesn't stop the iPhone 14 from being damn good at most things it does......»»
Soybean virus may give plant-munching bugs a boost in survival
Most viral infections negatively affect an organism's health, but one plant virus in particular—soybean vein necrosis orthotospovirus, often referred to as SVNV—may actually benefit a type of insect that commonly feeds on soybean plants and can t.....»»
Treating antibiotic-resistant infections with peptides inspired by human saliva
Antibiotic resistance is a problem that impacts tens of millions of people each year worldwide. According to the CDC, "more than 2.8 million antibiotic-resistant infections occur in the United States each year, and more than 35,000 people die as a re.....»»
Shape of coronavirus affects its transmission, study finds
Since the start of the COVID-19 pandemic, images of the coronavirus, SARS-CoV-2, have been seared in our minds. But the way we picture the virus, typically as a sphere with spikes, is not strictly accurate. Microscope images of infected tissues have.....»»
Creating an artificial protein shell to combat COVID-19
During the first COVID-19 wave, when Saumitra Das and colleagues were sequencing thousands of samples every day to check for SARS-CoV-2 variants as part of INSACOG, the Government of India's genome surveillance initiative, they were racing against ti.....»»
Scientists uncover how SARS-CoV-2 blocks antiviral defenses
Researchers at the Francis Crick Institute have found one way SARS-CoV-2 manipulates the environment within human cells to prevent them raising a full antiviral response......»»
Engineered multivalent self-assembled binder protein against SARS-CoV-2 RBD
Since it appeared in 2019, COVID-19 has claimed over 6 million lives and upended society across the globe. The condition, caused by the SARS-CoV-2 virus, attacks cells in the lungs, heart and brain, among other organs. Researchers soon realized that.....»»
Modified nucleotides used in COVID-19 vaccines work as designed
The remarkable effectiveness of mRNA vaccines against SARS-CoV-2 has generated much interest in synthetic mRNA therapeutics for treating and preventing disease. But some basic science questions have remained about whether the modified nucleotides use.....»»
Biologists discover how cancer-causing virus avoids triggering immune system response
The human immune system is a complex network of organs, cells and proteins that defend the body against infections and diseases. While our bodies work constantly to ensure invading infections don't breach the defenses, viruses are working just as har.....»»
SARS-CoV-2 has evolved an incubation time more like seasonal coronaviruses
Meta-analysis finds the gap between infection and symptoms has gradually shortened. Enlarge (credit: Getty | picture alliance) The incubation period for COVID-19—the time between when SARS-CoV-2 first infects a person and wh.....»»
Study finds filovirus antibodies in Australian bats
Researchers from CSIRO, Australia's national science agency, have detected antibodies to a filovirus in Australian bats for the first time......»»
SARS-CoV-2 genomic recombination is uncommon but disproportionately occurs in spike protein region
An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to attach to and infect host cells......»»
Scientists identify mechanism crucial for COVID-19 virus replication
A team led by UT Southwestern researchers has identified how SARS-CoV-2, the virus that causes COVID-19, builds a structure called the RNA cap that's critical for successful viral replication. The finding, published in Nature, could lead to new strat.....»»
To break through bacteria"s protective shield, target the shield-maker
Antibiotic-resistant bacteria are making it increasingly difficult to combat many infections. And types of bacteria classified as "Gram-negative"—which refers to the Gram staining method used to differentiate bacteria—are particularly hard to com.....»»
The mystery gene that helps mice survive virus infections
Researchers from UNSW Sydney have discovered that a particular transposable element, or jumping gene, in the genome has a profound effect on the immune response to virus infection......»»
Understanding how motor proteins shape our cells
Understanding the busy networks inside our cells can help researchers develop new cancer treatments and prevent dangerous fungal infections......»»
The Risk of Heart Disease after COVID
Some studies suggest that the risk of cardiovascular problems, such as a heart attack or stroke, remains high even many months after a SARS-CoV-2 infection clears up.....»»
Early-life acquisition of antimicrobial resistance in newborn children from low- and middle-income countries
Every year, almost 7 million potentially serious bacterial infections are estimated to occur in newborns, resulting in more than 550,000 annual neonatal deaths. Most of these infections and deaths happen in LMICs, where often scarce resources can lim.....»»
Kids" noses can better fight COVID-19
University of Queensland-led research has found the lining of children's noses is better at inhibiting SARS-CoV-2 infections than adult noses......»»
Newly developed COVID-19 test detects and identifies specific variants with 100% accuracy
University of California, Irvine researchers have developed a COVID-19 test that detects and identifies specific SARS-CoV-2 variants with 100% accuracy. In a study, the RNA-encoded viral nucleic acid analytic reporter correctly determined the Alpha,.....»»
