There's More to Life Than Being Happy

There's More to Life Than Being Happy | Fragments of Science | Scoop.it
In September 1942, Viktor Frankl, a prominent Jewish psychiatrist and neurologist in Vienna, was arrested and transported to a Nazi concentration camp with his wife and parents. Three years later, when his camp was liberated, most of his family, including his pregnant wife, had perished -- but he, prisoner number 119104, had lived. In his bestselling 1946 book, Man's Search for Meaning, which he wrote in nine days about his experiences in the camps, Frankl concluded that the difference between those who had lived and those who had died came down to one thing: Meaning, an insight he came to early in life. When he was a high school student, one of his science teachers declared to the class, "Life is nothing more than a combustion process, a process of oxidation." Frankl jumped out of his chair and responded, "Sir, if this is so, then what can be the meaning of life?"

Learning from Earth's Smallest Ecosystems (Kavli Hangout)

Learning from Earth's Smallest Ecosystems (Kavli Hangout) | Fragments of Science | Scoop.it
Peering into the planet's tiniest ecosystems, under rocks and in our guts.

 

"From inside our bodies to under the ocean floor, microbiomes — communities of bacteria and other one-celled organisms — thrive everywhere in nature. Emerging at least 3.8 billion years ago, they molded our planet and created its oxygen-rich atmosphere. Without them, life on Earth could not exist. 

Yet we know surprisingly little about the inner workings of nature's smallest and most complex ecosystems. "

Scientists discover impossible hydrogen bond

Scientists discover impossible hydrogen bond | Fragments of Science | Scoop.it

Scientists have discovered a new type of hydrogen bond which was previously considered impossible or at least highly improbable.

"The discovery is significant because hydrogen bonds are such a fundamental part of both chemistry and biology," says Professor Henrik Kjærgaard from the Department of Chemistry at the University of Copenhagen. "They form the basis of biological molecules and it’s for instance hydrogen bonds that determine the boiling point of water."

He led the new study, which has been published in the Journal of Physical Chemistry Letters.

Generating broadband terahertz radiation from a microplasma in air | Fragments of Science | Scoop.it
Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. They demonstrate that an approach for generating terahertz waves using intense laser pulses in air can be done with much lower power lasers, a major challenge until now. They have exploited the underlying physics to reduce the necessary laser power for plasma generation.

Intact Proteins Found in Fossils That Are Supposedly 8-18 Million Years Old

Intact Proteins Found in Fossils That Are Supposedly 8-18 Million Years Old | Fragments of Science | Scoop.it
Recently, I ran across a very interesting study that adds to the list of surprises for those who think that some fossils are millions of years old. The authors were analyzing the fossilized shells of an extinct group of marine mollusks from the genus Ecphora. Unlike many mollusk groups, the fossilized shells of the Ecphora are colored reddish-brown. The authors decided to find out what produces this colorization, so they soaked the fossils in weak acid to remove the minerals. What remained were thin sheets of organic residue that had all the characteristics one would expect if they were made of proteins.

Dark matter is ghostly and non-interactive

Dark matter is ghostly and non-interactive | Fragments of Science | Scoop.it
A new study of colliding galaxy clusters has found that dark matter doesn't even interact with itself.

"We have concluded that dark matter is most probably not interacting, so it exists in its ghostly state without interacting," says the study's lead author Dr David Harvey of the École Polytechnique Fédérale de Lausanne in Switzerland.

"This is surprising because we see in our world that all the particles interact with each other quite highly, whereas dark matter does not seem to do that."

Astronomers first noticed dark matter when they realised that there wasn't sufficient gravitational attraction to keep stars orbiting as fast as they do around the centres of galaxies.

Another apparently invisible substance, which scientists now call dark matter, must be providing the additional gravity.

Scientists estimate that dark matter makes up 85 per cent of all the matter in the universe.

All the normal matter - which makes up all the stars, planets, dust and gas clouds (which scientists call baryonic matter) - makes up just 15 per cent of all the matter in the universe.

Take a look at your body like never before — from the intricate geometry of your hormones to the tiny architecture of the microbes that infect you — in this selection of images from the new book Science is Beautiful. 

Here, a colored scanning electron micrograph of empty fat cells. Fat cells, or adipocytes, are amongst the largest cells in the human body. They form a thick insulating layer under the skin which serves to cushion us as well as to store energy.

In this image the normal lipid (fat) deposits of the cells have been removed, revealing the honeycomb structure of the cell membranes.

New Spin on Spintronics: Radiation-resistant Material May Enable Devices in Harsh Environments

New Spin on Spintronics: Radiation-resistant Material May Enable Devices in Harsh Environments | Fragments of Science | Scoop.it
A team of researchers is exploring new materials that could yield higher computational speeds and lower power consumption, even in harsh environments. Most modern electronic circuitry relies on controlling electronic charge within a circuit, but this control can easily be disrupted in the presence of radiation. Electronics that use spintronics may offer an alternative that is robust even in radiation-filled environments.
