Research sheds light on the role of PTPRK in tissue repair and cancer      (via sciencedaily.com)     Original source 

New research has advanced our knowledge of multiple roles for PTPRK, a receptor tyrosine phosphatase linked to the regulation of cell-cell adhesion, growth factor signalling and tumor suppression. Through a characterization of the function of PTPRK in human cell lines and mice, the team distinguished catalytic and non-catalytic functions of PTPRK. The findings extend what is known about the signalling mechanisms involving PTPRK as a phosphatase and its role in colorectal health but also shed new light on the extent of its function via non-catalytic signalling mechanisms.

3D-printed microstructure forest facilitates solar steam generator desalination      (via sciencedaily.com)     Original source 

Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing. They present technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion. Their SSGs were inspired by plant transpiration and are composed of miniature tree-shaped microstructures, forming an efficient, heat-distributing forest.

Controlling mosquito populations through genetic breeding      (via sciencedaily.com)     Original source 

Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.

Transient structure in fly leg holds clue to insect shape formation      (via sciencedaily.com)     Original source 

A little leg may reveal something big about how closely related insect species can drastically differ in body shape, according to a new study. The team imaged live cells of fruit flies in the last stages of development over several days and found a new structure that appears to help guide a section of the leg into its final shape.

Come closer: Titanium-48's nuclear structure changes when observed at varying distances      (via sciencedaily.com)     Original source 

Researchers have found that titanium-48 changes from a shell model structure to an alpha-cluster structure depending on the distance from the center of the nucleus. The results upend the conventional understanding of nuclear structure and are expected to provide clues to the Gamow theory on the alpha-decay process that occurs in heavy nuclei, which has not been solved for nearly 100 years.

Genome recording makes living cells their own historians      (via sciencedaily.com)     Original source 

Genomes can now be used to store information about a variety of transient biological events inside of living cells, as they happen, like a flight recorder collecting data from an aircraft. The method, called ENGRAM, aims to turn cells into their own historians. ENGRAM couples each kind of biological signal or event inside a cell to a symbolic barcode. This new strategy traces and archives the type and timing of biological signals inside the cell by inserting this information into the genome. For example, this record-keeping can track the commands that turn genes on or off.
