A butterfly’s first flight inspires a new way to produce force and electricity

Posted by in categories: biotech/medical, engineering

The wings of a butterfly are made of chitin, an organic polymer that is the main component of the shells of arthropods like crustaceans and other insects. As a butterfly emerges from its cocoon in the final stage of metamorphosis, it will slowly unfold its wings into their full grandeur.

During the unfolding, the chitinous material becomes dehydrated while blood pumps through the veins of the butterfly, producing forces that reorganize the molecules of the material to provide the unique strength and stiffness necessary for flight. This natural combination of forces, movement of water, and molecular organization is the inspiration behind Associate Professor Javier G. Fernandez’s research.

The hunt for dark matter is further along than you think

Posted by in category: cosmology

Dark matter isn’t just floating around filling up empty space. Importantly, it is found in clumps and structures, similar to ordinary matter. It forms the structure onto which ordinary matter gloms and is thought to be responsible for the structures of galaxies and the universe as a whole.

“We know that galaxies form in the scaffold that dark matter produces,” astronomer and early universe researcher Steve Wilkins of the University of Sussex explained. “It is an integral part of our universe to explain what we see.”

“We don’t have a firm theoretical handle on what dark matter should be.”

A Giant Planet Seems to Be Lurking Unseen in Our Solar System

Posted by in categories: habitats, space

Our Solar System is a pretty busy place. There are millions of objects moving around – everything from planets, to moons, to comets, and asteroids. And each year we’re discovering more and more objects (usually small asteroids or speedy comets) that call the Solar System home.

Astronomers had found all eight of the main planets by 1846. But that doesn’t stop us from looking for more. In the past 100 years, we’ve found smaller distant bodies we call dwarf planets, which is what we now classify Pluto as.

Tiny Thermoelectric Device Restores Thermal Perception in Phantom Limb

Posted by in categories: augmented reality, biotech/medical, cyborgs, satellites, wearables

Summary: Researchers created a revolutionary tiny and efficient thermoelectric device, which can help amputees feel temperature with their phantom limbs.

Known as the wearable thin-film thermoelectric cooler (TFTEC), this device is lightweight, incredibly fast, and energy-efficient, potentially revolutionizing applications such as prosthetics, augmented reality haptics, and thermally-modulated therapeutics. Additionally, this technology has potential in industries like electronics cooling and energy harvesting in satellites.

The study conducted to test the TFTEC demonstrated its ability to elicit cooling sensations in phantom limbs, doing so significantly faster, with more intensity, and less energy than traditional thermoelectric technology.

Ned Block — Toward a Science of Consciousness

Posted by in categories: neuroscience, science

Watch more interviews on the mystery of consciousness: https://bit.ly/41Bs4NV

How can consciousness be addressed scientifically? The Tucson conference, founded in 1994 and celebrating its 20th anniversary in 2014, exemplifies the quest. What are the range of theories? Where do participants position themselves? Meet the founders, early visionaries, new scientists and thinkers. Progress is being made, but what does this really mean?

Fragile X Syndrome: New Hopes of Treatment For Genetic Disorder

Posted by in categories: biological, chemistry, genetics, neuroscience

Fragile X syndrome is a genetic disorder caused by a mutation in a gene that lies at the tip of the X chromosome. It is linked to autism spectrum disorders.

People with fragile X experience a range of symptoms that include cognitive impairment, developmental and speech delays and hyperactivity. They may also have some physical features such as large ears and foreheads, flabby muscles and poor coordination.

‘Twinkle, Twinkle, Little Star’ Suddenly Has A New Meaning, Say Scientists

Posted by in category: futurism

Stars appear to twinkle because our atmosphere bends and distorts starlight as it travels to Earth. But stars also have an innate “twinkle” of their own, says new study.

Genetically engineered trees stoke climate hope — and environmental fears

Posted by in categories: bioengineering, climatology, genetics, sustainability

“O poplar tree, O poplar tree, how carbon-dense are thy branches …”

Trees are a major tool in our fight against climate change by sucking up carbon dioxide, but one company is taking them a step further: genetically engineering trees to sequester even more carbon. U.S. climate technology startup Living Carbon is developing genetically engineered seedlings of a hybrid poplar that it says can accumulate up to 53% more biomass than control plants and thereby absorb 27% more carbon.

Plants use sunlight to turn water and carbon dioxide into oxygen and sugar, a process known as photosynthesis. Living Carbon says its trees, a hybrid of the common aspen (Populus tremula) and white poplar (P. alba), can do it better with genetic changes to boost its photosynthetic performance.
