PANDORGA ESPECIAL - EPISÓDIO INÉDITO

Pandorga está de volta para encerrar as comemorações dos 50 anos da TVE

No sábado, 29 de março, a TVE fecha o ciclo do cinquentenário e comemora 51 anos de televisão pública no Rio Grande do Sul com a exibição de um Pandorga inédito, às 10h45 da manhã. A turma de bonecos formada por Nina, Beti, Jura, Tinta, Zé Cão e tantos outros fará parte das atrações de um Jornal Legal “muito especial”, que contará com auditório, matérias e entrevistas inéditas, além da reprise de quadros do programa Pandorga. Tudo sob o comando dos apresentadores “Anete E-mail” – a pedagoga e atriz Maria Inês Falcão, idealizadora do programa – e “Carlos@” – o ator Oscar Simch, que integrou o grupo do Pandorga a partir dos anos 1990.

O programa será comentado, diretamente de uma arquibancada, por produtores, atores e bonequeiros que participaram de diferentes fases do Pandorga: Iara de Almeida, João Brites, Joice de Brito e Cunha, Laura Medina, Lúcia Achutti, Maria Lúcia Melão, Mario de Ballentti e Vera Vergo. Além disso, haverá uma edição inédita do Diário da Nina, em que a boneca conta sobre sua visita à Terreira da Tribo de Atuadores Ói Nóis Aqui Traveiz, e uma matéria do Tinta Repórter, que conversa com alunos do Colégio Santa Cecília sobre a retirada dos celulares da sala de aula neste ano.

Criado em 1988 e exibido em temporadas até 2015, o Pandorga marcou pelo menos duas gerações de crianças, não apenas gaúchas, pois foi transmitido na programação da TV Brasil e exibido em diversos países. Com uma linguagem bem regional, abordava temas do cotidiano das crianças do Rio Grande do Sul, como educação e leitura, ecologia, brincadeiras e questões de consumo. O programa inovou ao utilizar técnicas de manipulação direta e cenários em miniatura, conquistando prêmios como o Açorianos de Literatura e o da Associação Gaúcha de Teatro de Bonecos. Tudo isso embalado pela canção “Papagaio, Pandorga”, de Gelson Oliveira.

Herpes Virus Linked to Long-Term Brain and Neurological Problems

Summary: A new study reveals that herpes simplex virus-1 (HSV-1), commonly known for causing cold sores, can travel through the nasal cavity directly to the brain, causing severe and lasting neurological symptoms. In animal experiments, nasal HSV-1 infection led to persistent neurological dysfunction, including anxiety and cognitive impairment.

The researchers identified heparanase, a cellular enzyme, as a critical factor in allowing HSV-1 to cause severe, lasting neurological damage. Blocking the activity of this enzyme significantly reduced neurological damage in infected animals, highlighting a possible therapeutic target.

Good question! I tried to work this out from the ripe age of 17, but it took me until my fourth year of undergraduate until I understood it fully. Here is the more 'technical' answer on where it comes from and why James Clerk Maxwell managed to unify it with the electric force:

One way to think about magnetism is that it is the 'relativistic correction' to the electrostatic force. This is because all information (including the spread/continual update of electric fields as charges move) can not travel faster than the speed of light.
Thus, only 
moving charge particles feel a magnetic force in a m

Exercise Boosts Memory Across All Ages

Summary: New research finds that nearly any form of exercise can enhance brain function and memory across the lifespan. This large-scale umbrella review analyzed data from over 258,000 participants and found that low- to moderate-intensity activities like yoga, Tai Chi, and even exergames significantly benefit cognition.

Children and teens saw the greatest memory gains, while people with ADHD experienced notable improvements in executive function. The findings highlight that even small bursts of movement can have profound cognitive effects, making exercise an accessible and essential brain-health strategy for everyone./.../

FROM THE ARCHIVE | The Healing Power of Gardens: Oliver Sacks on the Psychological and Physiological Consolations of Nature

“I work like a gardener,” the great painter Joan Miró wrote in his meditation on the proper pace for creative work. It is hardly a coincidence that Virginia Woolf had her electrifying epiphany about what it means to be an artist while walking amid the flower beds in the garden at St. Ives. Indeed, to garden — even merely to be in a garden — is nothing less than a triumph of resistance against the merciless race of modern life, so compulsively focused on productivity at the cost of creativity, of lucidity, of sanity; a reminder that we are creatures enmeshed with the great web of being, in which, as the great naturalist John Muir observed long ago, “when we try to pick out anything by itself, we find it hitched to everything else in the universe”; a return to what is noblest, which means most natural, in us. There is something deeply humanizing in listening to the rustle of a newly leaved tree, in watching a bumblebee romance a blossom, in kneeling onto the carpet of soil to make a hole for a sapling, gently moving a startled earthworm or two out of the way. Walt Whitman knew this when he weighed what makes life worth living as he convalesced from a paralytic stroke: “After you have exhausted what there is in business, politics, conviviality, love, and so on — have found that none of these finally satisfy, or permanently wear — what remains? Nature remains; to bring out from their torpid recesses, the affinities of a man or woman with the open air, the trees, fields, the changes of seasons — the sun by day and the stars of heaven by night.”/.../

Fine particulate matter exposure increases the risk of developing dementia

Q&A with an expert: Dr. Katrin Burkhart (Assistant Professor at IHME) presents new results that suggest exposure to fine particulate matter (PM2.5) increases the risk of developing all types of dementia.
IHME published a new analysis in Nature Aging to understand the relationship between fine particulate matter (PM2.5) and the risk of developing all types of dementia. The analysis also studied two major subtypes of dementia, Alzheimer’s disease and vascular dementia./.../

National and provincial burden of disease attributable to fine particulate matter air pollution in China, 1990–2021: an analysis of data from the Global Burden of Disease Study 2021


Interpretation

Despite the decline in the disease burden attributable to total PM2·5 in China during 1990–2021, ambient PM2·5 remains a major contributor to mortality and disability. This study highlights considerable spatial heterogeneity across different provinces and provides valuable insights for developing geographically tailored strategies for PM2·5 control and public health promotion in China. Stricter control of ambient air pollution is needed in northern and northwestern regions, while promoting clean cooking energy is more urgently warranted in southwestern areas.

Studying the state of health and disparities to understand trends 

State of health and inequalities among Italian regions. Chart shows "life expectancy at birth"on the y-axis and "year" on the y-axis. Life expectancy at birth in Italy dropped to 82.2 years in 2020 due to COVID-19 and slightly recovered to 82.7 in 2021.

A new study published in The Lancet Public Health analyzed trends and geographical differences
 in disease burden across Italian regions from 2000 to 2021. IHME study authors and collaborators used health metrics to understand how health outcomes differed at national, macro-regional, and subnational levels. 

Studying and understanding the state of health in one country can help inform regional trends. Highlights from this research:
  • Life expectancy at birth in Italy increased from 79.6 years in 2000 to 83.4 years in 2019, dropped to 82.2 years in 2020 due to COVID-19, and recovered slightly to 82.7 in 2021. Healthy life expectancy (HALE) was 70.9 years in 2021.
     
  • Overall, the top causes of years with lived disability (YLDs) were low back pain, falls, and headache disorders. Additionally, anxiety and depressive disorders both had substantial increases from 2019 to 2021 (19.8% and 17.3%, respectively).
     
  • YLDs for Alzheimer’s disease and diabetes increased substantially from 2000 to 2019 and 2019 to 2021 (70.6% and 3.0% for Alzheimer’s disease and 46.8% and 7.9%, for diabetes, respectively, for each timepoint).

Researchers discovered bright ultraviolet (UV) light coming from an ancient,
distant galaxy. The findings, published March 26 in the journal
 Nature,
suggest that the universe's first stars modified their surroundings even
earlier than expected.

Shortly after the Big Bang, the universe was a soup of protons, neutrons and
electrons. As the universe cooled, the protons and neutrons combined to
form positively charged hydrogen ions, which then attracted negatively
charged electrons to create a fog of neutral hydrogen atoms. This fog
absorbed light with short wavelengths, such as UV light, blocking it from
reaching farther into the universe.

But as the first stars and galaxies formed, they emitted enough UV light to
knock the electrons back off the hydrogen atoms, allowing UV light out once
again. Though this "Era of Reionization" is thought to have ended about a
billion years after the Big Bang, scientists still aren't sure exactly when the
first stars formed — or when the Era of Reionization began.

PORTLAND, US, Mar 4 2025 (IPS) - As the world’s population increased five-fold since the start of the 20th century, the changes in the geographic distribution of the billions of people across the planet have been ongoing and significant.

Those continuing changes in the distribution of the world’s population have weighty economic, political, social and environmental consequences (Table 1).

 Particularly noteworthy are the changing proportions of the world’s population living in Africa and Europe. At the start of the 20th century the proportions of the world’s population residing in Africa and Europe were 8% and 25%, respectively. By the end of that century, the proportions were similar, 13% for Africa and 12% for Europe. By 2050, however, the proportions of the world’s population residing in Africa and Europe are expected to be very different at 26% and 7%, respectively (Figure 1).

Trends in the global, regional, and national burden of oral conditions from 1990 to 2021: a systematic analysis for the Global Burden of Disease Study 2021 - Published February 27, 2025, in The Lancet 

Background

The WHO Global Oral Health Action Plan has set an overarching global target of achieving a 10% reduction in the prevalence of oral conditions by 2030. Robust and up-to-date information on the global burden of oral conditions is paramount to monitor progress towards this target. The aim of this systematic data analysis was to produce global, WHO region, and country-level estimates of the prevalence of, and disability-adjusted life-years (DALYs) attributed to, untreated caries, severe periodontitis, edentulism, other oral disorders, lip and oral cavity cancer, and orofacial clefts from 1990 to 2021.
