Complex coacervate droplets as a model material for studying the electrodynamic response of biological materials
Manipulating solid particles of a few micrometers in size using an electric field has been of great interest to physicists. These controllable particles can be assembled into dynamic chains that can effectively control the flow of liquids in thin tubes like capillaries. Replacing these solid particles with liquid droplets would allow for previously unachievable electrorheology applications in...
Oft-overlooked grasslands build biodiversity, resilience over centuries
Grasslands' biodiversity and resilience to disturbances such as fire, heat and drought is the result of a slow process over hundreds of years, like that of old growth forests, finds new CU Boulder-led research.
Fruit flies: Summer pests or scientific marvel?
Fly-swatting season is here. No sooner will you place your fresh strawberries on the kitchen counter than will the first fruit fly arrive. It won't take long for a platoon of Drosophila buddies to be hovering about the spoils.
Up a creek without paddle? Researchers suggest 'gunwale bobbing'
Stand up in a canoe and you'll probably find yourself in the water before too long. Jump up and down on the upper edges of the sides of the canoe, and you'll likely end up in the drink as well. But get the balance right and you'll be able to move yourself along by as much as one meter per second, according to a study published in Physical Review Fluids examining gunwale bobbing.
Plant-based 'beef' reduces CO2 emissions but threatens 1.5M ag jobs

Plant-based alternatives to beef have the potential to help reduce carbon dioxide emissions, but new economic models show their growth in popularity could disrupt the agricultural workforce, threatening more than 1.5 million industry jobs.
Mitochondrial DNA mutations linked to heart disease risk

Researchers report a surprising link between mitochondria, inflammation and gene mutations that may increase risk of atherosclerosis.
Five of the top discoveries aboard NASA's Curiosity rover on Mars
Revealing the potentially habitable climate of ancient Mars is a key part of NASA's mission to explore and understand the unknown, to inspire and benefit humanity—and for 10 years, the Curiosity rover has been on the case at the Red Planet.
Data on plant 'sweating' could help predict wildfire severity
A new study uses data from the ECOSTRESS instrument aboard the space station to better understand why some parts of a wildfire burn more intensely than others.
Researchers harness the power of carbenes to fabricate drugs more easily and more safely
Despite being some of the most versatile building blocks in organic chemistry, compounds called carbenes can be too hot to handle. In the lab, chemists often avoid using these highly reactive molecules due to how explosive they can be.
The U.S Will Soon Have Space Force Ambassadors Around the World
First come the warriors, then come the diplomats. It was on December 20, 2019, that the National Defense Authorization Act was signed, creating the U.S. Space Force, the first new branch of the military to come into being in the 72 years since the Air Force was established. The Space Force’s remit was not just to protect U.S. assets, like spy satellites, from attacks by hostile nations; it...
Researchers explore how floods and droughts are challenging science and society globally
Floods, droughts, and other water-related disasters are some of the costliest natural events that occur in Canada and around the world. Even with significant global advances in science and infrastructure designed to predict and manage such extreme disasters, many communities still face major societal and economic impacts when these events occur.

- 22/8/4 20:56
Tropical coastal ecosystems are among the most biodiverse areas on Earth. And they're also on the front lines of effects caused by human activity. That's why it's becoming increasingly important, especially as human populations increase, to manage the impacts of runoff and wastewater that flow into the sea.
Hyaluranic acid, a naturally occurring compound, awakens stem cells to repair damaged muscle

A new study reveals a unique form of cell communication that controls muscle repair.
How pathogenic gene variants lead to heart failure

Cardiomyopathy is not a uniform disease. Rather, individual genetic defects lead to heart failure in different ways, an international consortium reports.
Single-cell approaches and deep learning to map all stages of fruit fly embryo development
- ScienceDaily
- 22/8/4 20:55
Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to different developmental defects and provides a path to understand the vast non-coding part of our genome that contains most disease-associated mutations.
These baboons borrowed a third of their genes from their cousins
- ScienceDaily
- 22/8/4 20:55
Genetic analyses of baboons in Kenya reveals that most of them carry traces of hybridization in their DNA. As a result of interbreeding, about a third of their genetic makeup consists of genes from another, closely-related species. Fifty years of observations turned up no obvious signs that hybrids fare any worse than their counterparts. But the new findings suggest that appearances can be...
Team discovers new plant gene reprogramming mechanism
Researchers Albert Cairó and Karel Riha of the Central European Institute of Technology (CEITEC) and their colleagues have discovered a previously unknown mechanism that is responsible for reprogramming gene expression in plants during the transition period when one cell differentiates into another one. The mechanism occurs at the end of meiosis, a specialized cell division essential for sexual...
'Indescribable': the heat and roar of Iceland's volcano
The ground rumbles underfoot, then roars as red-orange lava fountains shoot up from the ground, the intense heat cloaking the nearby crowd awestruck by Iceland's latest volcanic eruption.
Scientist studies how torrential rainfall will change our rivers
Beneath the surface of rivers lurks a hazard that isn't well understood—but could wreak havoc on people and communities near the water.
Researchers trace the source of nitrogen pollution affecting the world's second largest barrier reef
Tropical coastal ecosystems are among the most biodiverse areas on Earth. They're also on the front lines of effects caused by human activity. That's why it's becoming increasingly important, especially as human populations increase, to manage the impacts of runoff and wastewater that flow into the sea.
