Bioengineers develop lotus leaf-inspired system to advance study of cancer cell clusters      (via sciencedaily.com)     Original source 

Bioengineers have harnessed the lotus effect to develop a system for culturing cancer cell clusters that can shed light on hard-to-study tumor properties. The new zinc oxide-based culturing surface mimics the lotus leaf surface structure, providing a highly tunable platform for the high-throughput generation of three-dimensional nanoscale tumor models.

Strength training activates cellular waste disposal      (via sciencedaily.com)     Original source 

The elimination of damaged cell components is essential for the maintenance of the body's tissues and organs. An international research team has made significant findings on mechanisms for the clearing of cellular wastes, showing that strength training activates such mechanisms. The findings could form the basis for new therapies for heart failure and nerve diseases, and even afford benefits for manned space missions.

Colorful traits in primates ease tensions between groups      (via sciencedaily.com)     Original source 

Primate ornamentation plays a crucial role in communication not only within social groups but also between them, according to a new study. The research reveals that the males of species with overlapping home ranges often display vibrant colors or elaborate features, traits that may help reduce intergroup aggression by enabling quick assessments of potential rivals.

Revealing DNA behavior in record time      (via sciencedaily.com)     Original source 

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists have developed a technique that speeds up screening of individual DNA molecules at least a thousand times. With this technology, they can measure millions of DNA molecules within a week instead of years to decades.

Creature the size of a dust grain found hiding in California's Mono Lake      (via sciencedaily.com)     Original source 

Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.

T cells manipulate the memory of innate immune cells      (via sciencedaily.com)     Original source 

Research reveals that T cells from the adaptive immune system can manipulate the memory of innate immune cells. Previously, it was believed that the memory of innate immune cells operated independently. This surprising connection opens up new possibilities for the treatment of various diseases. A mouse model shows that no immunosuppressive drugs are needed after an organ transplantation if this interaction between T cells and the innate immunity is temporarily blocked after the transplantation.

Fighting coastal erosion with electricity      (via sciencedaily.com)     Original source 

New research has systematically demonstrated that a mild zap of electricity can strengthen a marine coastline for generations -- greatly reducing the threat of erosion in the face of climate change and rising sea levels. The new process forms natural cement between grains of sand, transforming it into solid, immoveable rock. Mollusks use a similar process to turn naturally occurring minerals into shells.

From pets to pests: How domestic rabbits survive the wilderness      (via sciencedaily.com)     Original source 

How do rabbits go from fluffy pets to marauding invaders? Rabbits have colonized countries worldwide, often with dire economic and ecological consequences, but their secret has until now been a mystery. Biologists sequenced the genomes of nearly 300 rabbits from across three continents to unveil the key genetic changes that make these animals master colonizers.

Catalyst for 'one-step' conversion of methane to methanol      (via sciencedaily.com)     Original source 

Scientists have engineered a highly selective catalyst that can convert methane, a major component of natural gas, into methanol, an easily transportable liquid fuel, in a single, one-step reaction. This direct process for methane-to-methanol conversion runs at a temperature lower than required to make tea and exclusively produces methanol without additional byproducts.

Pollution drives families to relocate -- but only the rich can afford to live in healthier areas      (via sciencedaily.com)     Original source 

Pollution levels factor in households' decision to relocate within the United States, but only richer households can afford areas with improved air quality, a new study finds. Researchers analyse detailed origin and destination information of relocating households, rather than just aggregate migration flows, and uncover a direct link between a household's income and their new chosen county of residence. They find inequalities exist when it comes to who is exposed to the worst areas of pollution -- with poorer families hit hardest. Richer households opt to move into cleaner, healthier areas that tend to be more expensive. However poorer families are priced out of these counties and are the ones who move into areas with higher levels of toxic releases.

Gut molecule slows fat burning during fasting      (via sciencedaily.com)     Original source 

In a struggle that probably sounds familiar to dieters everywhere, the less a Caenorhabditis elegans (C. elegans) worm eats, the more slowly it loses fat. Now, scientists have discovered why: a small molecule produced by the worms' intestines during fasting travels to the brain to block a fat-burning signal during this time.

Next time you beat a virus, thank your microbial ancestors      (via sciencedaily.com)     Original source 

When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research, two key elements of our innate immune system came from a group of microbes called Asgard archaea.

Life from a drop of rain: New research suggests rainwater helped form the first protocell walls      (via sciencedaily.com)     Original source 

New research shows that rainwater could have helped create a meshy wall around protocells 3.8 billion years ago, a critical step in the transition from tiny beads of RNA to every bacterium, plant, animal, and human that ever lived.

A deep dive for environmental data on coastal oceans      (via sciencedaily.com)     Original source 

A new study addresses the lack of data on how much human-generated carbon dioxide is present in coastal oceans -- the saltwater ecosystems that link the land and sea. Capturing this data is crucial to calculating how much emissions must be cut in the future.
