Published Cells of the future: A key to reprogramming cell identities



The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.
Published One small material, one giant leap for life on Mars: New research takes us a step closer to sustaining human life on the red planet



Researchers have discovered the transformative potential of Martian nanomaterials, potentially opening the door to sustainable habitation on the red planet.
Published The evolutionary timeline of diminished boric acid and urea transportation in aquaporin 10



Aquaporin (Aqp) 10 water channels in humans allow the free passage of water, glycerol, urea, and boric acid across cells. However, Aqp10.2b in pufferfishes allows only the passage of water and glycerol and not urea and boric acid. Researchers sought to understand the evolutionary timeline that resulted in the variable substrate selection mechanisms among Aqp10s. Their results indicate that Aqp10.2 in ray-finned fishes may have reduced or lost urea and boric acid permeabilities through evolution.
Published New study examines the relationship between the rate of wound healing, the circadian rhythm, and 'hair' on cells



Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis. Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.
Published Protein allows poison dart frogs to accumulate toxins safely



A newly identified protein helps poison dart frogs accumulate and store a potent toxin in their skin which they use for self-defence against predators.
Published Ringing in the holidays with ringed planet Uranus



NASA's James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features -- including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength coverage for a more detailed look.
Published Genetic diversity of wild north American grapes mapped



Wild North American grapes are now less of a mystery after researchers decoded and catalogued the genetic diversity of nine species of this valuable wine crop.
Published Genetics of host plants determine what microorganisms they attract



Plants often develop communities with microorganisms in their roots, which influences plant health and development. Although the recruitment of these microbes is dictated by several factors, it is unclear whether the genetic variation in the host plants plays a role.
Published Algae as a surprising meat alternative and source of environmentally friendly protein



A new study has demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults. Their findings suggest that algae may be an interesting and sustainable alternative to animal-derived protein with respect to maintaining and building muscle.
Published Genetic atlas detailing early stages of zebrafish development



Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types.
Published Acid sensor and calcium store discovered in plants



Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store.
Published Scientists measure the distance to stars by their music



A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe.
Published New red galaxies turn out to be already known blue galaxies



Not all discoveries turn out to be actual new discoveries. This was the case for the extremely red objects (EROs) found in James Webb Space Telescope (JWST) data. Analysis shows that they are very similar to blue-excess dust obscured galaxies (BluDOGs) already reported in Subaru Telescope data.
Published Astronomers discover first population of binary stripped stars



Astronomers have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars that are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers.
Published How the immune system fights to keep herpes at bay



In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell nucleus, a poorly understood terrain of host-pathogen interaction. The findings could inform the design of new treatments for herpes and other viruses that replicate in the same way.
Published New understanding of ancient genetic parasite may spur medical breakthroughs



Researchers have determined the structure of the most common material in our genomes. New treatments for autoimmune diseases, cancer and neurodegeneration may follow.
Published Unexpected chemistry reveals cosmic star factories' secrets



Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists. Using powerful telescopes to split the galaxies' light into individual colors, the scientists were amazed to discover light from many different molecules -- more than ever before at such distances. Studies like this could revolutionize our understanding of the lives of the most active galaxies when the universe was young, the researchers believe.
Published Tiniest free-floating brown dwarf



Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable with giant planets, weighing just a few times the mass of Jupiter.
Published Enzymes can't tell artificial DNA from the real thing



Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab.
Published Scientists unveil complete cell map of a whole mammalian brain



Researchers have created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity between these cells.
