Illuminating tissue formation through flourescence
Researchers at ETH Zurich have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumors, the molecule could play a significant role in research of wound healing disorders......»»
Damage to cell membranes causes cell aging, finds new study
Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue injury. To cope with such damage, cells are equipped w.....»»
Black hole fashions stellar beads on a string
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling be.....»»
Music education, support networks, and continuity are key factors regulating adolescents" arts participation, says study
How do young people find their way to music-making? Researchers Anna Kuoppamäki from the University of the Arts Helsinki and Fanny Vilmilä from the Finnish Youth Research Network identified factors that had a significant impact on the formation of.....»»
Paleontological analysis shows renowned fossil thought to show soft tissue preservation is in fact just paint
A 280-million-year-old fossil that has baffled researchers for decades has been shown to be—in part—a forgery, following new examination of the remnants......»»
Important molecular pathway for control of aging discovered
One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) in Brazil found that when t.....»»
New insights in the regulation of genetic information exchange
Within every cell in our body, our DNA is tightly bundled with proteins to form structures known as chromosomes. The commonly known shape of a chromosome relates to an X-shaped appearance in many organisms. The formation of the X-shaped chromosome re.....»»
Researchers design gel from wood pulp to heal damaged heart tissue, improve cancer treatments
You can mend a broken heart this Valentine's Day now that researchers have invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments......»»
A new approach to producing artificial cartilage with the help of 3D printing
Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken toward creating replacement tissue in the lab—using a technique that differs significantly from oth.....»»
Which came first: Black holes or galaxies?
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests......»»
New 3D printing method uses ice to build a template for artificial blood vessels in engineered tissue
Over 100,000 individuals in the United States are currently in need of organ transplants. The demand for organs, such as hearts, kidneys, and livers, far exceeds the available supply and people sometimes wait years to receive a donated organ. Approxi.....»»
New AI tool discovers realistic "metamaterials" with unusual properties
A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue—these extraordinary objects are already made from "metamaterials." Researchers from TU Delft have now developed an AI tool that not only can discove.....»»
Hubble spies baby stars being born amid chaos of interacting galaxies
Amid swirling gas and dust pulled by gravitational forces of interacting galaxies, there can be bursts of star formation, creating new generations of stars......»»
Novel hydroxyapatite-targeting nanodrug may be a paradigm shift for cancer treatment
A multidisciplinary research team at Vanderbilt University and Vanderbilt University Medical Center has discovered a new way to kill a tumor by disrupting its acidic "microenvironment" without harming normal tissue......»»
Results from South Pole Telescope"s new camera emerge
For more than five years, scientists at the South Pole Telescope in Antarctica have been observing the sky with an upgraded camera. The extended gaze toward the cosmos is picking up remnant light from the universe's early formation. Now researchers h.....»»
Trained AI system learns to design cellular materials for tissue engineering, energy storage
Artificial structures called cellular materials have a network of internal spaces within a solid cell-like matrix. Their porous foam-like architecture combines advantages of low density with strength. Researchers at the National Institute for Materia.....»»
Understanding jasmonic acid: A switch that activates autophagy in Arabidopsis petals
Organogenesis, an important aspect of flowering, helps reveal key processes of plant development such as the formation of floral organs, attainment of reproductive capability, and abscission leading to seed and fruit development......»»
Secondary eyewall formation in upper- and lower-layer vertical wind shear simulated in idealized tropical cyclones
About 80% of intense tropical cyclones (TCs) possess concentric eyewalls—namely, the primary and secondary eyewalls. The intensity of the TC can vary considerably during secondary eyewall formation (SEF) and eyewall replacement, posing a great chal.....»»
Study challenges classical view of the Antarctic Circumpolar Current origin and warns of its vulnerability
The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study led by the University of Barcelona, the Instituto.....»»
Team discovers mechanism that protects tissue after faulty gene expression
A study at the University of Cologne's CECAD Cluster of Excellence in Aging Research has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead.....»»
How did life get started on Earth? Atmospheric haze might have been the key
A recent study accepted to The Planetary Science Journal and currently posted to the arXiv preprint server investigates how the organic hazes that existed on Earth between the planet's initial formation and 500 million years afterwards, also known a.....»»
