Science Snapshots: Dinosaur blood vessels, giant viruses, and antibiotic-building enzymes.
New research by a team from the Virginia Institute of Marine Science and University of Western Australia reveals that species of the seagrass genus Posidonia have evolved a remarkable adaptation for ocean survival: a winged seed whose shape harnesses the force of underwater currents to hold it on the seafloor for rooting.
Researchers of the Hubrecht Institute (KNAW - The Netherlands) and the Max Planck Institute in Münster (Germany) have revealed how an essential protein helps to activate genomic DNA during the conversion of regular adult human cells into stem cells. Their findings are published in the Biophysical Journal.
Experts have been unable to explain why cells from bacteria to humans leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites -- substances involved in the chemical processes to sustain life with production of complex molecules and energy -- may provide cells both selfish and selfless benefits.
DGIST identified causes of hypersensitivity accompanied by neurodevelopmental disorder such as autism-spectrum disorder (ASD). This is expected to make huge contributions to the early diagnosis of sensory-defective symptom brought with neurodevelopmental disorder and cancer as well as the improvement of anti-cancer drug side effects.
The smallest proteins travel in our cells, completing deeply important tasks to keep our molecular mechanisms moving. They are responsible for transporting cargo, duplicating cells and more. Now, a research team based in Japan has uncovered more about how these proteins move.
The CDI team's findings could ultimately improve cancer treatments for people of advanced age, like that of adult acute myeloid leukemia (AML).
Scientists explain how to increase the sensitivity of biosensors to the point where they can be integrated into smartphones, smart watches, and other wearable devices. The proposed solution can be not only easily fabricated but also integrated with materials like graphene oxide for providing adsorption of the biomolecules on the sensitive part of the optical elements.
Bioengineers from Trinity College Dublin, Ireland, have developed a prototype patch that does the same job as crucial aspects of heart tissue. Their work essentially takes us one step closer to being able to mend a broken heart.
Japanese scientists elucidated characteristics of PAS through observing the Atg protein using a fluorescence microscope and successfully reconstituted PAS in vitro. The team revealed, for the first time, that PAS is in the state of liquid droplets formed by liquid-liquid phase separation of Atg13 together with other Atg proteins and that this liquid droplet is responsible for autophagy.
