Published 3D printing with coffee: Turning used grounds into caffeinated creations
(via sciencedaily.com) Original source Coffee could be the key to reducing 3D printing waste, according to a new study. Researchers have developed a method for 3D printing using a paste made out of old coffee grounds.
Published You say tomato, these scientists say evolutionary mystery
(via sciencedaily.com) Original source Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.
Published Super antifreeze in cells: The ability to survive in ice and snow developed in animals far earlier than we thought
(via sciencedaily.com) Original source More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.
Published Researcher helps boost immune system memory against influenza
(via sciencedaily.com) Original source Researchers are one step closer to making the T cell army stronger. In a recent study, researchers found that by manipulating one molecular signaling pathway in the T cells that participate in clearing influenza virus in the lungs, the strength and longevity of immunological memory produced can be improved.
Published Auxin signaling pathway controls root hair formation for nitrogen uptake
(via sciencedaily.com) Original source Root hairs represent a low-cost strategy to enhance nutrient uptake because they can significantly increase the nutrient-acquiring surface of plant roots. While primary and lateral roots are stimulated to elongate when plants grow under mild nitrogen deficiency, the existence of such a foraging response for root hairs and its underlying regulatory mechanism remain elusive. Now, researchers have revealed a framework composed of specific molecular players meditating auxin synthesis, transport and signaling that triggers root hair elongation for nitrogen acquisition.
Published Malaria-causing parasites resistant to both treatment and detection have emerged in Ethiopia
(via sciencedaily.com) Original source Genomic surveillance has revealed mutations in malaria-causing parasites that will complicate efforts to eradicate the disease in Africa.
Published Nutrients drive cellular reprogramming in the intestine
(via sciencedaily.com) Original source Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation -- where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.
Published These worms have rhythm
(via sciencedaily.com) Original source Researchers have developed a new imaging technique to observe active gene expression in real time. They found that four molecules work together to control the timing of each stage of the C. elegans worm's development. This timekeeping process could provide important clues about the natural rhythm of development in humans and other animals.
Published Bacteria generate electricity from wastewater
(via sciencedaily.com) In a breakthrough for the field of bioelectronics, researchers have enhanced the ability of E. coli bacteria to generate electricity. The innovative approach only offers a sustainable solution for organic waste processing while outperforming previous state-of-the-art technologies, opening new horizons for versatile microbial electricity production.
Published New at-home test for gingivitis protects oral health
(via sciencedaily.com) Original source Engineers have developed a new device that can warn consumers about early risks of tooth decay from diseases such as gingivitis and periodontitis.
Published Scientists unlock secrets of red blood cell transporter, potentially paving the way for new drugs
(via sciencedaily.com) Original source Researchers have identified the structure of a special transporter found in red blood cells and how it interacts with drugs. Details on the findings could lead to the development of more targeted medicines. The research team found that this transporter facilitates the movement of a substance called bicarbonate, which certain drugs can inhibit. They discovered how these drugs block the transporter and devised novel compounds capable of achieving the same effect.
Published Atomic-scale spin-optical laser: New horizon of optoelectronic devices
(via sciencedaily.com) Researchers have pushed the limits of the possible in the field of atomic-scale spin-optics, creating a spin-optical laser from monolayer-integrated spin-valley microcavities without requiring magnetic fields or cryogenic temperatures.
