TEDx Talks (November 9, 2023) – Competition is a core part of human nature, and it can drive us to extraordinary feats. But when it goes wrong, the results can be devastating.
Poker champion and science communicator Liv Boeree introduces us to the dark force of game theory driving many of humanity’s biggest social problems — a force that’s now threatening to derail the AI industry.
Olivia “Liv” Boeree is a British science communicator, television presenter and former professional poker player. She is a World Series of Poker and European Poker Tour champion, and is the only female player in history to win both a WSOP bracelet and an EPT event.
nature Magazine – November 9, 2023:The latest issue cover features the changes in dopamine signals in male zebra finches (depicted on the cover), as they engage in activities such as drinking, song evaluation and courting. The researchers found that dopamine responses are dynamically adjusted based on the birds’ current priorities.
TEDx Talks (November 4, 2023) – Approximately 1.5 billion years ago, a lone bacterium found its way into a larger cell. The exchanges that transpired between the two are considered to have driven the evolution of this bacterium into the organelle we now call the mitochondrion.
Emerging research suggests that mitochondria are not simply the ‘powerhouses’ of the cell, but also function as cellular guardians against microbial intruders. Consequently, maintaining mitochondrial health is not only vital for our well-being, but may serve to protect us against infectious disease.
Dr. Lena Pernas started as a Max Planck Research Group Leader at the MPI Biology for Ageing (Cologne, Germany) in late 2018, where her lab investigates the organelle and metabolic dynamics of the host-pathogen interaction. Her lab will open its doors at UCLA in the Metabolism Research Theme in 2023.
The Economist (November 2, 2023) – As the most complex organ in your body, your brain changes radically throughout your life. Starting from before birth and continuing even after you’ve died. This is what happens to your brain as you age.

nature Magazine – November 2, 2023: The latest issue cover features an artist’s impression of the collision between the protoplanet Theia and proto-Earth about 4.5 billion years ago. It has been suggested that it was this ‘Giant Impact’ that formed the Moon, but direct evidence for the existence of Theia remains elusive.
Science Magazine – October 27, 2023: The new issue features The Hypothalamus – Coordinating basic survival functions; High hopes for low-growing corn plants; A quantum process in a laser microchip….
If you pause for a second and think about the activities that occupy most of your day, presumably sleeping, eating, and engaging in social interactions are among the first that come to your mind. Perhaps surprisingly, a small area buried deep inside the brain, called the hypothalamus, is responsible for coordinating neuronal signals related to these activities. By controlling the homeostasis of the neuroendocrine, limbic, and autonomic nervous systems, the hypothalamus is a key brain region for many physiological and pathological processes. Despite its small size, the hypothalamus has a complex cellular organization and circuitry that determine its structural and functional organization. It is composed of 11 nuclei grouped by their location and has vast, mostly bidirectional connections with many neuronal and endocrine systems.
Plants bred or engineered to be short can stand up better to windstorms. They could also boost yields and benefit the environment
To an interstate traveler—or anyone lost in a corn maze—the most impressive feature of corn is its stature. Modern corn can grow twice as tall as a person, but height has drawbacks, making the plants vulnerable to wind and more difficult for farmers to tend. Plant scientists think corn can be improved by making it shorter, and leading seed companies are doing that through both conventional breeding and genetic engineering. Bayer has launched a short variety in Mexico, another company is selling its versions in the United States, and more are getting involved.

In August, the Sun rose behind the Extremely Large Telescope, under construction in Chile.
Past the halfway point, Extremely Large Telescope prepares to receive first mirrors
A web of steel girders is rising from the flattened summit of Cerro Armazones, 3000 meters above sea level in Chile’s Atacama Desert. The dome it will support will be vast—with a footprint as big as a soccer field and almost as tall as the Statue of Liberty— and unexpectedly nimble: It will smoothly rotate on rails as a giant telescope inside tracks stars through the night.
