Contrariando o senso comum, novo longa de Kleber Mendonça Filho tem recorde de público, mas não ganha novas salas.

Sequência de "Wicked" larga com mais de mil de salas e mostra que mesmo o indicado do país ao Oscar precisa lutar contra o lobby hollywoodiano.
“O Agente Secreto” bate recorde de público, mas amarga menos de 20% de presença nas salas de cinema
#Edição 125 | Indicado brasileiro ao Oscar vê filmes como "Wicked 2" com muito mais atenção nas salas do Brasil e escancara problema crônico do audiovisual nacional

C'mon guys. Cells show blebbing and death was inhibited by caspase inhibitors and had mitochondrial permeabilization.

Getting Rosalind Franklin’s story right is crucial, because she has become a role model for women going into science

What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

📣 NEW STUDY 📣 @cp-immunity.bsky.social by Maria Lafaille's lab shows how long-lived IgE-producing plasma cells survive & sustain allergy without continued allergen exposure: maturing in spleen & bone marrow with a unique survival program that resists cell-death signals 🧐 www.cell.com/immunity/abs...
Long-lived IgE plasma cells that reside in the spleen contribute to the persistence of the IgE response
Allergies can persist even in the absence of allergen exposure. Miranda-Waldetario et al. find that IgE-producing plasma cells mature, acquire survival adaptations, and persist for extended periods of...

In recent years, experts have been warning that social media harms children. Should it be banned for younger users, like cigarettes, or regulated, like junk food?
Is Social Media More Like Cigarettes or Junk Food?
Lawmakers attempting to regulate children’s access to social media must decide whether bans or warning labels are the optimal route for keeping kids safe.

Two out of every three people with Alzheimer’s are women, and the greatest risk factor after old age is being a woman. A Nature Outlook article shows how a decade of research studying the effects of sex and gender on the disease is starting to bear fruit. #medsky #alzsky 🧪
Why women experience Alzheimer’s disease differently from men
Sex and gender research could lead to better, more equitable treatments — if it is allowed to continue without political interference.

Warming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level rise, according to a study in Communications Earth & Environment. 🧪
Warming of +1.5 °C is too high for polar ice sheets - Communications Earth & Environment
Warming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level rise, meaning that only a return to +1 °C or lower will avoid extensive loss and damage to coastal populations, according to a synthesis of recent evidence.
