Mosquitoes sense infrared from body heat to help track humans down, study shows
While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases of dengue, yellow fever, Zika and other diseases ev.....»»
Honey bees may play key role in spreading viruses to wild bumble bees
Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers at Penn State who analyzed seasonal trends of parasite and virus transmission in bees......»»
Cellular DNA damage response pathways might be useful against some disease-causing viruses
New research reveals that triggering a cell's DNA damage response could be a promising avenue for developing novel treatments against several rare but devastating viruses for which no antiviral treatments exist, possibly including human papilloma vir.....»»
Unveiling the intricate and subtle dance of proteins: Understanding how parasites disarm host defenses
Pathogens hijack host cell functions by expressing or secreting effector proteins, creating environments conducive to their survival and reproduction. These pathogenic microorganisms—including eukaryotic parasites, prokaryotic bacteria, and viruses.....»»
New insights on how bird flu crosses the species barrier
In recent years, public health measures, surveillance, and vaccination have helped bring about significant progress in reducing the impact of seasonal flu epidemics, caused by human influenza viruses A and B. However, a possible outbreak of avian inf.....»»
New tools for fungicide resistance detection
Researchers at the Center for Crop and Disease Management (CCDM) have developed a new method for detecting fungicide resistance, enabling them to detect multiple mutations, both known and novel, in just one test......»»
Detecting climate change using aerosols
Climate change is one of the most significant environmental challenges of present times, leading to extreme weather events, including droughts, forest fires, and floods. The primary driver of climate change is the release of greenhouse gases into the.....»»
Controversial New Guidelines Would Diagnose Alzheimer’s Before Symptoms Appear
Diagnosis of Alzheimer's, according to expert recommendations, can proceed by detecting the disease's underlying biology, even before the onset of cognitive decline.....»»
Ancient viral elements in RNA kickstart bone repair
Around half of the human genome is composed of DNA fragments originating from ancient viruses. These "transposable elements" (TEs) are now known to play various roles in modulating gene expression and disease development. Now, an international team l.....»»
Coinfecting viruses obstruct each other"s cell invasion
The process by which phages—viruses that infect and replicate within bacteria—enter cells has been studied for over 50 years. In a new study, researchers from the University of Illinois Urbana-Champaign and Texas A&M University have used cutting-.....»»
Cosmic microwave background experiments could probe connection between cosmic inflation, particle physics
Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale scientific efforts aimed at detecting and studying CMB.....»»
Lethal bird flu could decimate Oceania"s birds—from vigilance to vaccines, here"s what Australia is doing to prepare
Avian influenza viruses have infected the world's birds for millennia. We first became aware of them in the 19th century, when mass deaths of poultry triggered interest in what was then called "fowl plague.".....»»
New model explains precise timing of viral cell bursting
New research from Rice University scientists is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena......»»
Study shows ancient viruses fuel modern-day cancers
Peek inside the human genome and, among the 20,000 or so genes that serve as building blocks of life, you'll also find flecks of DNA left behind by viruses that infected primate ancestors tens of millions of years ago......»»
Influenza viruses can use a second entry pathway to infect cells, study shows
Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers at the University of Zurich have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway,.....»»
Low-cost cellphone-based Raman spectrometer system can identify unknown biological molecules within minutes
Imagine knowing what berry or mushroom is safe to eat during a hike or swiftly detecting pathogens in a hospital setting that would traditionally require days to identify......»»
Study: Nanoparticle vaccines enhance cross-protection against influenza viruses
To offer cross-protection against diverse influenza virus variants, nanoparticle vaccines can produce pivotal cellular and mucosal immune responses that enhance vaccine efficacy and broaden protection, according to a study by researchers in the Insti.....»»
Non-destructive method developed for detecting internal cracks in rice seeds
Recently, a team led by Prof. Wang Rujing and Wang Liusan from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a method to detect internal cracks in rice seeds using near-infrared spectroscopy......»»
Detecting defects in tomorrow"s technology: Study enhances understanding of likely candidate for next-generation chips
Silicon computer chips have served us well for more than half a century. The tiniest features on chips currently sold are approximately 3 nanometers—a startlingly small size given that a human hair is roughly 80,000 nanometers wide. Reducing the si.....»»
