Creating a C4-like vein pattern in rice by manipulating SHORT ROOT and auxin levels
C4 plants are distinguished by a unique leaf structure known as Kranz anatomy, characterized by inner vascular bundle sheath cells and outer mesophyll cells. This specialized arrangement confers C4 plants with several advantages over C3 plants, inclu.....»»
Structure of a central component of the human immune system revealed
A central component of the human immune system, the NLRP3 inflammasome plays an important role in fighting off infections. However, its chronic activation is also implicated in a variety of common diseases, such as Alzheimer's, Parkinson's, multiple.....»»

Famed Halley"s comet passes aphelion this weekend
It's lonely out there in the frozen outer solar system. On Saturday, December 9th, that most famous of all comets 1P/Halley reaches a hallmark point on its 75-year journey through the solar system, reaching aphelion or its most distant point from the.....»»
A mathematical model connects the evolution of chickens, fish and frogs
One of the most enduring, basic questions of life is: How does it happen? For instance, in human development, how do cells self-organize into skin, muscles or bones? How do they form a brain, a finger, a spine?.....»»
Melting fire-ice: Study finds climate change can cause methane to be released from the deep ocean
New research has shown that fire-ice—frozen methane which is trapped as a solid under our oceans—is vulnerable to melting due to climate change and could be released into the sea......»»
Identifying the fish species present in a river based on traces of their DNA
As they swim around, fish leave DNA fragments behind them, for example via their skin or their excrements. Once collected and analyzed, these indicators allow scientists to determine all the species present in the environment. What's more, the method.....»»

Research reveals clever dosage control mechanism of biallelic genes
Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene—one allele per chromosome or p.....»»
A close look at changes to the skin biome after ear piercing
A team of microbiologists at McGill University's Redpath Museum, working with a colleague at Tattoo Lounge MTL, has investigated changes to the skin microbiome when a person has an ear pierced and a metal object inserted into the puncture. In their s.....»»
Distant stars spotted for the first time in the vast Magellanic Stream
For nearly fifty years, astronomers have come up empty-handed in their search for stars within the sprawling structure known as the Magellanic Stream. A colossal ribbon of gas, the Magellanic Stream spans nearly 300 moon diameters across the Southern.....»»
Reprogramming tissue mechanically to promote wound healing
Researchers at PSI and ETH Zurich have taken connective tissue cells that have been mechanically reprogrammed to resemble stem cells and transplanted them into damaged skin. In their laboratory experiment, they were able to show that this can promote.....»»
