CERN congratulates 2019 physics Nobel Prize winners

Posted by in categories: cosmology, evolution, physics

CERN congratulates James Peebles, Michel Mayor and Didier Queloz on the award of the Nobel Prize in physics “for contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos”. Peebles receives the prize “for theoretical discoveries in physical cosmology” and Mayor and Queloz are recognised “for the discovery of an exoplanet orbiting a solar-type star”.

Cosmology studies the universe’s origin, structure and ultimate fate. Peebles’ theoretical framework of cosmology, developed since the mid-1960s, is the foundation of our knowledge of the cosmos today. Thanks to his seminal theoretical work, physicists now have a model that can describe the universe from its earliest moments to the present day, and into the distant future.

Meanwhile, Mayor and Queloz have explored our cosmic neighbourhood and announced in 1995 the first discovery of an exoplanet – a planet outside our Solar System – orbiting a solar-type star in the Milky Way. The discovery of this exoplanet, dubbed 51 Pegasi b, was a milestone in astronomy and has since led to the discovery of more than 4000 exoplanets in our galaxy.

How science has shifted our sense of identity

Posted by in categories: biological, science

In the iconic frontispiece to Thomas Henry Huxley’s Evidence as to Man’s Place in Nature (1863), primate skeletons march across the page and, presumably, into the future: “Gibbon, Orang, Chimpanzee, Gorilla, Man.” Fresh evidence from anatomy and palaeontology had made humans’ place on the scala naturae scientifically irrefutable. We were unequivocally with the animals — albeit at the head of the line.


Biological advances have repeatedly changed who we think we are, writes Nathaniel Comfort, in the third essay of a series marking Nature’s anniversary on how the past 150 years have shaped science today. Biological advances have repeatedly changed who we think we are.

Brain tunes itself to criticality, maximizing information processing

Posted by in categories: biological, computing, neuroscience

Researchers long wondered how the billions of independent neurons in the brain come together to reliably build a biological machine that easily beats the most advanced computers. All of those tiny interactions appear to be tied to something that guarantees an impressive computational capacity.

Over the past 20 years, evidence mounted in support of a theory that the tunes itself to a point where it is as excitable as it can be without tipping into disorder, similar to a phase transition. This criticality hypothesis asserts that the brain is poised on the fine line between quiescence and chaos. At exactly this line, is maximized.

However, one of the key predictions of this theory—that criticality is truly a set point, and not a mere inevitability—had never been tested. Until now. New research from Washington University in St. Louis directly confirms this long-standing prediction in the brains of freely behaving animals.

New research furthers understanding about what shapes human gut microbiome

Posted by in categories: biological, genetics, health

EVANSTON, Ill. — A new Northwestern University study finds that despite human’s close genetic relationship to apes, the human gut microbiome is more similar to that of Old World monkeys like baboons than to that of apes like chimpanzees.

These results suggest that human ecology has had a stronger impact in shaping the human gut microbiome than genetic relationships. The results also suggest the human gut microbiome may have unique characteristics compared to other primates, including increased flexibility.

“Understanding what factors shaped the human gut microbiome over evolutionary time can help us understand how gut microbes may have influenced adaptation and evolution in our ancestors and how they interact with our biology and health today,” said Katherine Amato, lead author of the study and assistant professor of anthropology in the Weinberg College of Arts and Sciences at Northwestern.

China Grows Cotton Plant on the Far Side of the Moon in Biological First

Posted by in categories: bioengineering, biological, space

China has broken new lunar ground, successfully growing cotton on the moon for the first time. The experiment was part of the Chang’e 4 project, in which China is exploring the far side of the moon with a lander. This is the same lander that recently discovered a mysterious gel-like substance on the moon’s surface.

The cotton plant was one of several organisms encased in a mini biosphere weighing just 2.6 kilograms (5.7 lbs) with a pressure of 1 atmosphere which was aboard the lander. The organisms experienced an environment largely similar to that on Earth, however, they did have to contend with both space radiation and microgravity.

In an interview with engineering magazine IEEE Spectrum, project leader for the experiment Xie Gengxin explained more about the challenges of growing plants in the restricted environment. “The weight of the Chang’e-4 probe demanded that the weight [of the experiment] can’t exceed three kilograms,” he said. That’s why it was important to select the biological samples in the experiment carefully.

29-Year-Old French Entrepreneur Creates Light Without Electricity

Sandra Rey, 29, was participating in a student design competition with the theme “biology” and got to watching videos on YouTube of bioluminescent sea creatures when she thought there must be a way to replicate that natural technology. Five years later, her startup, called Glowee, is creating brilliant luminescent art installations for hotels and public spaces.

While she admits, “We’ll never replace the lights in your kitchen,” she hopes to create enough light and enough beauty to play a role in the world’s lighting mix to help reduce reliance on electric lighting.

How Will We Store Three Septillion Bits of Data? Your Metabolome May Have the Answer

Posted by in categories: biological, computing, information science, neuroscience

For the “big data” revolution to continue, we need to radically rethink our hard drives. Thanks to evolution, we already have a clue.

Our bodies are jam-packed with data, tightly compacted inside microscopic structures within every cell. Take DNA: with just four letters we’re able to generate every single molecular process that keeps us running. That sort of combinatorial complexity is still unheard of in silicon-based data storage in computer chips.

Add this to the fact that DNA can be dehydrated and kept intact for eons—500,000 years and counting—and it’s no surprise that scientists have been exploiting its properties to encode information. To famed synthetic biologist Dr. George Church, looking to biology is a no-brainer: even the simple bacteria E. Coli has a data storage density of 1019 bits per cubic centimeter. Translation? Just a single cube of DNA measuring one meter each side can meet all of the world’s current data storage needs.
