Published How eavesdropping viruses battle it out to infect us
(via sciencedaily.com) Original source Dozens of viruses -- at least -- can eavesdrop on host information. Not only did they demonstrate the strategy's abundance, but they also discovered tools that control it and send signals that tell bacteriophage viruses to flip from chill (lysogeny) into kill (lysis) mode. They showed that in polylysogeny, phages can coexist, their viral DNA or RNA hidden tucked inside the bacterium's own, replicating right along with the cells. But the infiltrating phages aren't exactly peaceful; it's more like mutually assured destruction. And the tenuous detente lasts only until something triggers one or more of the phages to switch into kill mode.
Published New findings offer potential breakthrough in HIV cure research
(via sciencedaily.com) Original source The results of a novel study has revealed exciting findings in the pursuit of an HIV cure.
Published Western science catches up with First Nations' medicinal use of ant honey
(via sciencedaily.com) Original source Scientists have discovered the honey produced by Australian ants possesses unique anti-microbial activity against bacteria and fungi that could make the liquid useful medicinally.
Published Washable, transparent, and flexible OLED with MXene nanotechnology?
(via sciencedaily.com) Transparent and flexible displays, which have received a lot of attention in various fields including automobile displays, bio-healthcare, military, and fashion, are in fact known to break easily when experiencing small deformations. To solve this problem, active research is being conducted on many transparent and flexible conductive materials such as carbon nanotubes, graphene, silver nanowires, and conductive polymers.
Published Monkeypox: Characterization of post-infectious immune response
(via sciencedaily.com) Original source In 2022-2023, an outbreak of monkeypox, now known as mpox (caused by the monkeypox virus or MPXV) led to 87,000 human cases in 170 countries. Most cases were reported outside the usual areas in which the virus circulates. Since the outbreak began, surveillance of the virus has been stepped up in Europe, with nearly 5,000 cases being reported in France.
Published Study explores how often children diagnosed with flu experience serious neuropsychiatric side effects
(via sciencedaily.com) Original source While the incidence of influenza-associated neuropsychiatric events in children in the United States is unknown, the controversy over the use of a common antiviral medication typically administered to treat flu in children has sparked concern among parents and medical professionals alike.
Published Revealing HIV drug-resistance mechanisms through protein structures
(via sciencedaily.com) Original source Researchers have discovered the molecular mechanisms by which the human immunodeficiency virus (HIV) becomes resistant to Dolutegravir, one of the most effective, clinically used antiviral drugs for treating HIV. Their findings reveal how changes to the 3D structures of integrase, an HIV protein, can lead to Dolutegravir resistance and how other compounds may be able to overcome this resistance.
Published Detection of bacteria and viruses with fluorescent nanotubes
(via sciencedaily.com) The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses.
Published Some people's brain function still affected by Long COVID years after infection
(via sciencedaily.com) Original source Researchers have found that people with longer-term COVID-19 symptoms including brain fog showed reduced performance in tasks testing different mental processes up to two years after infection with the virus.
Published Scientists develop AI-based tracking and early-warning system for viral pandemics
(via sciencedaily.com) Original source Machine-learning system effectively predicts emergence of prominent variants.
Published Fueled by new chemistry, algorithm mines fungi for useful molecules
(via sciencedaily.com) Original source A newly described type of chemistry in fungi is both surprisingly common and likely to involve highly reactive enzymes, two traits that make the genes involved useful signposts pointing to a potential treasure trove of biological compounds with medical and chemical applications. It was also nearly invisible to scientists until now.
Published Researchers put a new twist on graphite
(via sciencedaily.com) Original source Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.
Published Gene mutation may explain why some don't get sick from COVID-19
(via sciencedaily.com) Original source People who contract COVID-19 but never develop symptoms -- the so-called super dodgers -- may have a genetic ace up their sleeve. They're more than twice as likely as those who become symptomatic to carry a specific gene variation that helps them obliterate the virus, according to a new study.
Published 'Mind controlling' parasitic worms are missing genes found in every other animal
(via sciencedaily.com) Original source Parasitic hairworms manipulate the behavior of their hosts in what's sometimes called 'mind control.' A new study reveals another strange trait shared by different hairworm species: they're missing about 30% of the genes that researchers expected them to have. What's more, the missing genes are responsible for the development of cilia, the hair-like structures present in at least some of the cells of every other animal known.
Published Fungi blaze a trail to fireproof cladding
(via sciencedaily.com) Original source Scientists have shown it's possible to grow fungi in thin sheets that could be used for fire-retardant cladding or even a new kind of fungal fashion.
Published Ticks may be able to spread chronic wasting disease between Wisconsin deer
(via sciencedaily.com) Original source A new study finds that ticks can harbor transmissible amounts of the protein particle that causes Chronic Wasting Disease (CWD), implicating the parasites as possible agents in the disease's spread between deer in Wisconsin.
Published A bright future in eco-friendly light devices, just add dendrimers, cellulose, and graphene
(via sciencedaily.com) Original source Researchers have developed a light-emitting electrochemical cell using dendrimers, a material gaining popularity in the industry. Moreover, the team found that using biomass derived cellulose acetate as the electrolyte retains the cell's long-life span. Combined with a graphene electrode, the cell has the potential to light the way for a future of eco-friendly and flexible light-emitting devices.
Published 'Electronic skin' from bio-friendly materials can track human vital signs with ultrahigh precision
(via sciencedaily.com) Original source Researchers have used materials inspired by molecular gastronomy to create smart wearables that surpassed similar devices in terms of strain sensitivity. They integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.
Published Researchers develop digital test to directly measure HIV viral load
(via sciencedaily.com) Original source A milliliter of blood contains about 15 individual drops. For a person with human immunodeficiency virus (HIV), each drop of blood could contain anywhere from fewer than 20 copies of the virus to more than 500,000 copies. Called the viral load, this is what is measured to allow clinicians to understand how patients are responding to anti-viral medications and monitor potential progression. The time-consuming viral load testing needs to be repeated several times as a patient undergoes treatment. Now, a research team has developed a time and cost-efficient digital assay that can directly measure the presence of HIV in single drop of blood.
Published Some black truffles grown in eastern U.S. may be less valuable lookalike species, study finds
(via sciencedaily.com) Original source Black truffle growers are unintentionally growing less-expensive winter truffles, which may lead to mix-ups in the market as well.
