No jantar de encerramento do XI Congresso Mundial de Cardiologia, em Manila 1990.
Na foto de baixo estava conosco a saudosa Marianne Burle de Figueiredo, Secretária Executiva da Federação Mundial de Cardiologia, desde a época em que se chamava "International Society and Federation of Cardiology" Hoje, minha filha Lucia Helena, fazendo arrumação em guardados, encontrou as duas vestes que usamos na cerimônia. Foi a única vez que, além dos dados oficiais, passaporte, etc... solicitaram aos convidados, com meses de antecedência, as medidas corporais, para a confecção das vestes bordadas a mão... Na sessão de abertura, a Presidente Corazón Aquino esteve presente e, ao entrar no Salão de Atos, quando passou por nós (Valderês e eu), sentados na primeira fila da platéia, nos apertou as mãos como reperesentates dos demais congressistas. Vestíamos a tal jaqueta branca feita de um tecido, a partir de folha de bananeira, típico de lá
Corazon Aquino, in full Maria Corazon Aquino, née Maria Corazon Cojuangco, (born January 25, 1933, Tarlac province, Philippines —died August 1, 2009, Makati ), Philippine political leader who served as the first female president (1986–92) of the Philippines, three years after her husband's assassination, restoring democratic rule in that country after the long dictatorship of Ferdinand Marcos.

University of California, Irvine biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles.
Traditionally believed to originate from one brain circuit linking the thalamus and cortex, the team’s findings, published today in Scientific Reports, suggest that the axons in memory centers of the hippocampus play a role.
For decades, slow waves and sleep spindles have been identified as essential elements of deep sleep, measured through electroencephalography recordings on the scalp. However, the UC Irvine-led team revealed a novel source of these brain waves within the hippocampus and were able to measure them in single axons./.../
By uncovering the hippocampus’s role in generating slow waves and sleep spindles, this research expands our understanding of the brain’s activity during deep sleep and its impact on memory processing. Credit: Neuroscience News#
Last July, I read this memo to the staff and explained why I had made the difficult decision to move on from my role as Quanta’s editor-in-chief. This magazine has meant everything to me since I pitched the concept to the Simons Foundation in 2012. Building, growing, nurturing and leading the publication and staff — and being a part of what we’ve collectively accomplished — has been the most remarkable and rewarding experience of my career. And it’s been especially gratifying to see valued Quanta readers like you multiply twentyfold over the past decade, with many millions more engaging with our science and math content on socialmedia and YouTube, and through our podcasts and in translated reprintings around the world...
New research has uncovered a social world of viruses full of cheating, cooperation and other intrigues, suggesting that viruses make sense only as members of a community.
Black holes are inescapable traps for most of what falls into them — but there can be exceptions. The theoretical physicist Leonard Susskind speaks with co-host Janna Levin about the black hole information paradox and how it has propelled modern physics.

Number of Distances Separating Points Has a New Bound
By LEILA SLOMAN
Mathematicians have struggled to prove Falconer’s conjecture, a simple but far-reaching hypothesis about the distances between points. They’re finally getting close.

'Construindo um mundo global: migrantes através do Atlântico (1746 – 1753)' é o tema da Quinta Cultural desta semana, com Antero Ferreira (Casa de Sarmento - UMinho / CITCEM).11/04/2024 as 19h Pelo Facebook e Youtube https://www.youtube.com/watch?v=MLvkR9o526s#Nature Briefing
Hello Nature readers, Today we discover the first algae that can fix nitrogen, gaze upon the first direct image of a ‘Wigner crystal’ made only of electrons and consider evidence of a shared practice of human sacrifice across Stone Age Europe.
Each week Quanta Magazine explains one of the most important ideas driving modern research. This week, physics staff writer Charlie Wood describes some of the oddities and mysteries that swirl around the quantity that orders the universe and our lives — time.
How Physicists Are Exploring and Rethinking Time
By CHARLIE WOOD
Time is inextricably woven into what might be the most fundamental goal of physics — prediction. Whether they’re studying cannonballs, electrons or the entire universe, physicists aim to gather information about the past or present and project it forward to catch glimpses of the future. Time is, as Nobel Prize winner Frank Wilczek put it in a recent episode of Quanta’s The Joy of Why podcast, “the master variable under which the world unfolds.”
In addition to prediction, physicists face the challenge of understanding time as a physical phenomenon in its own right. They develop ever-sharper explanations of the most obvious feature of time in our daily lives: that it flows inexorably forward. And recent experiments showcase more exotic ways in which time can behave under the established laws of quantum mechanics and general relativity. As researchers deepen their understanding of time in these two cherished theories, they encounter puzzles that seem to bubble up from murkier, more fundamental levels of reality./.../

PBS Space Time has a detailed explainer video in which Matt O’Dowd describes how disorder aims the arrow of time from the past toward the future.
New Scientist hosted a 2020 lecture about the nature of time, available on YouTube, by Carlo Rovelli, a quantum gravity researcher who wrote a book on the subject.
Dark Energy May Be Weakening, Major Astrophysics Study Finds
By CHARLIE WOOD
A generation of physicists has referred to the dark energy that permeates the universe as “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years.
How the Ancient Art of Eclipse Prediction Became an Exact Science
By JOSHUA SOKOL Video by EMILY BUDER
The timing of the total eclipse on April 8, 2024, will be known to within a second, thousands of years after fearful humans first started trying to anticipate these cosmic events.
Researchers linked midlife stress and childhood trauma to an increased risk of Alzheimer’s disease and neuroinflammation. Analyzing 1,290 volunteers, researchers found that stressful life events, especially during midlife, correlate with higher levels of β-amyloid protein, crucial in Alzheimer's development, and that childhood stress is associated with later life neuroinflammation. Interestingly, the study also uncovered sex-specific effects, with stress leading to amyloid protein accumulation in men and brain atrophy in women.
A new Global Burden of Disease (GBD) article published in The Lancet on April 3 found significant changes in global causes of death, life expectancy, and mortality. From 1990 to 2021, global life expectancy increased by 6.2 years, despite the COVID-19 pandemic radically altering global causes of death.
Highlights from this research:
For the first time in 30 years, stroke was replaced as the second-leading cause of death in the world: COVID-19 became the second-leading cause of death in 2021.
Mortality from diarrhea, lower respiratory infections, stroke, and ischemic heart disease declined from 1990 to 2021.
Reductions in childhood mortality from diarrheal diseases came from combined efforts in improved immunization, clean water access, sanitation, hygiene facilities, breastfeeding, and oral rehydration therapy.
IHME’s Dr. Mohsen Naghavi discusses findings from the GBD 2021 cause of death paper in a comprehensive Q&A video. How has life expectancy changed from 1990 to 2021? What factors contributed to the global increase in life expectancy?
Super-region of Southeast Asia, East Asia, and Oceania saw the largest gains in life expectancy. These countries reduced mortality from chronic respiratory diseases, stroke, lower respiratory diseases, and cancer. They had strong COVID-19 management that preserved these gains.
