Published For microscopic organisms, ocean currents act as 'expressway' to deeper depths
(via sciencedaily.com) Original source Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
Published Scientists track 'doubling' in origin of cancer cells
(via sciencedaily.com) Original source Working with human breast and lung cells, scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.
Published Physicists arrange atoms in extremely close proximity
(via sciencedaily.com) Original source Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.
Published Scientists test for quantum nature of gravity
(via sciencedaily.com) Original source A new study reports on a deep new probe into the interface between the theories of gravity and quantum mechanics, using ultra-high energy neutrino particles detected by a particle detector set deep into the Antarctic glacier at the south pole.
Published Deeper understanding of malaria parasite development unlocks opportunities to block disease spread
(via sciencedaily.com) Original source Natural malaria infections have been genetically analysed at a higher resolution than ever before, giving insights that could help understand and block transmission.
Published Promising new treatment strategy for deadly flu-related brain disorders
(via sciencedaily.com) Original source Researchers have found that a brain disorder associated with flu (influenza-associated encephalopathy, or IAE) can be caused by the influenza virus entering the brain from the blood via endothelial cells. In these cells, the researchers observed viral protein accumulation, suggesting that antivirals targeting viral transcription/translation may be useful treatments for some patients. Given the lack of effective treatments for IAE, this finding will likely improve patient care and reduce IAE-related deaths worldwide.
Published Significant new discovery in teleportation research -- Noise can improve the quality of quantum teleportation
(via sciencedaily.com) Original source Researchers succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state.
Published Activation of innate immunity: Important piece of the puzzle identified
(via sciencedaily.com) Original source Researchers have deciphered the complex interplay of various enzymes around the innate immune receptor toll-like receptor 7 (TLR7), which plays an important role in defending our bodies against viruses.
Published When good bacteria go bad: New links between bacteremia and probiotic use
(via sciencedaily.com) Original source Researchers discovered a concerning association between bacteremia and probiotic use, particularly with Clostridium butyricum (C. butyricum) MIYAIRI 588. Whole-genome sequencing revealed that all C. butyricum bacteremia strains were probiotic derivatives. Out of 6,576 cases of positive blood cultures, C. butyricum was detected in only five cases, all derived from probiotics. The study underscores rare but serious adverse events linked to probiotics, advocating cautious prescribing practices, especially for hospitalized patients.
Published Medical school scientist creates therapy to kill hypervirulent bacteria
(via sciencedaily.com) Original source Researchers are on a mission to kill drug-resistant bacteria, and a new study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics.Researchers have shown that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It becomes a health hazard when it enters other parts of the body and can cause pneumonia, urinary tract and wound infections. Those at highest risk include seniors and patients with other health problems such as diabetes, cancer, kidney failure and liver disease.

Published Archaea can be picky parasites
(via sciencedaily.com) Original source A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic microbes, so-called DPANN archea. Their study shows that these archaea are very 'picky eaters', which might drive their hosts to change the menu.
Published The big quantum chill: Scientists modify common lab refrigerator to cool faster with less energy
(via sciencedaily.com) Original source Scientists have dramatically reduced the time and energy required to chill materials to temperatures near absolute zero. Their prototype refrigerator could prove a boon for the burgeoning quantum industry, which widely uses ultracold materials.
Published Identifying risks of human flea infestations in plague-endemic areas of Madagascar
(via sciencedaily.com) Original source Researchers uncover why some homes in rural Madagascar where bubonic plague is endemic are infested with fleas. Based on their findings, they recommend ways to reduce the flea populations and their impact on human health.
Published Researchers unlock potential of 2D magnetic devices for future computing
(via sciencedaily.com) Original source A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets -- a process akin to how flipping a light switch controls a bulb.
Published Key functions of therapeutically promising jumbo viruses
(via sciencedaily.com) Original source Viruses known as 'jumbo' phages are seen as a potential tool against deadly bacterial infections. But scientists must first decipher the extraordinary makeup of these mysterious viruses. Researchers have now uncovered a key piece of jumbo phage development that helps them counter bacteria.
Published Marriage of synthetic biology and 3D printing produces programmable living materials
(via sciencedaily.com) Original source Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid 'engineered living materials' are made by embedding cells in an inanimate matrix that's formed in a desired shape. Now, researchers have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.
Published Father's gut microbes affect the next generation
(via sciencedaily.com) Original source Researchers changed the composition of the gut microbiota in male mice through common antibiotics, inducing a condition called dysbiosis, and found that: - Mouse pups sired by a dysbiotic father show significantly lower birth weight, and have increased risk of growth disorders and postnatal mortality.
Published Calcium can protect potato plants from bacterial wilt
(via sciencedaily.com) Original source Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt.
Published Novel genetic plant regeneration approach without the application of phytohormones
(via sciencedaily.com) Original source Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.
