King's Williams Island Finland 1987 - colhendo flores silvestres...
O jardim, era de fato uma reserva ecológica, agreste numa ilha fronteiriça a Helsinki. As flores silvestre que colhemos eu guardei , e até algum tempo se conservavam (secas) protegidas por um plástico. Espero pode reencontrá-las, mesmo que não consiga mais encontrar quem as colheu. Abraço.

OBITUARY
C. Thomas Caskey (1938–2022)
Geneticist who demonstrated the universality of life’s code. Jan Witkowski
Geneticist C. Thomas Caskey demonstrated the universality of the genetic code, developed one of the earliest applications of DNA fingerprinting in forensic science, was key to the early phases of the Human Genome Project and helped to initiate personalized medicine. He was also a consummate story-teller with an instantly identifiable Southern drawl — and a passionate sailor. “Eminent scientists occasionally found themselves at sea in severe storms, fearing their imminent demise,” writes colleague Jan Witkowski. Caskey has died aged 83.
Nirenberg wrote: “These results had a profound philosophical impact on me because they indicate that all forms of life on this planet use essentially the same language.” Caskey also identified the signals that tell the cell’s protein-synthesis machinery when to stop translating a messenger RNA.

Scientists’ ability to experience wonder, awe and beauty in their work is associated with higher levels of job satisfaction and better mental health. Researchers surveyed more than 3,000 scientists — mainly biologists and physicists — in India, Italy, the United Kingdom and the United States. Far from the caricature of scientists as exclusively rational and logical beings, “this beauty stuff is really important”, says sociologist and co-author Brandon Vaidyanathan. “It shapes the practice of science and is associated with all kinds of well-being outcomes.”
Life expectancy at age 70 has continued to rise globally
A study from IHME found that decreases in non-communicable and chronic diseases led to a decline in mortality in populations over 70 years old. However, there are still large disparities between regions as high-income countries are more likely to experience longer life expectancy and healthier quality of life than low-income countries.
Annual health care spending on dementia increased by nearly 5% globally between 2000 and 2019. The burden of dementia is expected to continue increasing, according to new projections from IHME, as will the funding required to treat it. By 2050, we project that 11% of overall health care spending will be represented by dementia, and as much as 17% under alternative scenarios.
Un généraliste en pleine "désertification médicale"... à Paris
Si les praticiens sont nombreux au km2, c'est la faible quantité de médecins rapportée à la population qui vaut à la l'Île-de-France le qualificatif de "premier désert médical de France métropolitaine", selon l'URPS
Biomechanical interactions, rather than neurons, control the movements of one of the simplest animals. The discovery offers a glimpse into how animal behavior could have worked before neurons evolved.
Tiny Galaxies Reveal Secrets of Supermassive Black Holes
By CHARLIE WOOD
Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed.
Machine Learning Reimagines the Building Blocks of Computing
By NICK THIEME
The “lossy compression” inherent to many algorithms can result in false positives. Algorithms strengthened with machine learning can avoid these mistakes.
The noted mathematician and author Steven Strogatz explains how the conversations with experts in his new Quanta Magazine podcast address his lifelong fascination with timeless mysteries.
Atoms in our chaotic world ricochet like billiard balls, making it difficult for physicists to gauge their properties. Researchers recently found a way to stabilize the movement of certain atoms.
The Nine Lives of Schrödinger’s Cat Quantum theory’s predictions are clear, but its physical interpretation is not. IAI News invited nine physicists and philosophers to explain their interpretation of the Schrödinger’s cat thought experiment. One interpretation of quantum mechanics called “QBism” focuses on the beliefs of the observer rather than the physical reality of the object being observed. Amanda Gefter interviewed the founder of QBism, Christopher Fuchs, for Quanta in 2015.
Good News for the Scatterbrained Studying the entropy produced during various brain activities could lead to insights about how the mind works. Morten Kringelbach and Gustavo Deco write for Aeon about their thermodynamic theory of the mind. The neuroscientist Anil Seth also sees a connection between thermodynamics and the brain: He believes the brain actively fights against the 2nd law of thermodynamics by using predictive models to keep tight control over its processes.

A small pulsar has belched out an enormous beam of matter and antimatter particles that streamed for 40 trillion miles (64 trillion kilometers) across the Milky Way. Astronomers detected the cosmic particle trail in images captured in X-rays by NASA's Chandra X-ray Observatory in space and in optical light by the Gemini North telescope in Hilo, Hawaii.
Astronomers searching for our solar system's elusive Planet Nine — a theoretical world that may lurk deep in a cloud of icy rocks far beyond the orbit of Neptune — have come up short once again. In a recent paper published Dec. 23, 2021 in The Astrophysical Journal, researchers pored over six years of telescope data in an attempt to identify potential signs of Planet Nine in the southern sky. Captured with the Atacama Cosmology Telescope (ACT) in Chile between 2013 and 2019, the observations covered about 87% of the sky visible from the Southern Hemisphere.
