Catherine Wihtol de Wenden, politiste : « Le Maroc a pris conscience de la place géostratégique qu’il occupe pour l’Europe en termes de migrations »

A military base, a displaced people and Trump’s China fears: Burnham’s Chagos test

Mantener satélites en órbita terrestre muy baja es muy problemático, pero esta compañía española quiere convertir el problema en solución

La startup española Kreios Space se está preparando para hacer historia con el lanzamiento del primer satélite en órbita terrestre muy baja (VLEO) impulsado por propulsión eléctrica atmosférica. Este tipo de propulsión está ideada precisamente para que los satélites puedan operar en órbitas muy bajas, donde las imágenes de la Tierra son más nítidas, las mediciones más precisas y las comunicaciones mucho más optimizadas. Todo suena muy bien, pero mantener un vehículo a esa altitud es muy costoso por muchos motivos. Para solucionarlo, se deben buscar opciones novedosas, como la que propone…

Which 10 atmospheres are the Solar System’s thickest?

Our Solar System has gas giants, rocky planets, moons, asteroids, and more. By size, it’s clear that the gas giant worlds vastly outstrip any of the terrestrial planets, and this is true for mass as well. Although Saturn is nearly the same physical size as Jupiter, it contains just 21% of the planetary mass in the Solar System, compared to Jupiter’s whopping 71%. Mass is the largest factor in determining whether a planet has an atmosphere or not, but other factors such as temperature, history, and composition can play major roles as well.

Your brain may be wired to regain lost weight

Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss. This biological “memory” helps explain why many people regain weight after dieting and why medications such as Wegovy and Mounjaro can help by reducing appetite signals, although their effects may fade when treatment ends.

Two new compounds could reveal hidden drivers of Alzheimer’s disease

Vanderbilt researchers created the first selective compound designed to inhibit TAOK-1, a poorly understood protein connected to Alzheimer’s disease. They also discovered a second compound that activates the entire TAOK protein family, offering scientists an unexpected new research tool. Together, the compounds could reveal hidden disease mechanisms and point toward new treatment strategies.

Scientists may have found aging’s hidden trigger for brain disease

Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington’s. In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic proteins to clump together, damaging neurons and shortening lifespan. Reducing EPS8 activity prevented these harmful aggregates and preserved nerve function.

Non-invasive tests for the evaluation of liver fibrosis in MASLD

Nature Medicine, Published online: 03 August 2026; doi:10.1038/s41591-026-04560-x In the LITMUS imaging study, we assessed non-invasive alternatives to liver biopsy histopathology in metabolic dysfunction-associated steatotic liver disease (MASLD). Elastography and elastography-based composite scores had sufficient diagnostic accuracy to replace liver biopsy histopathology in evaluating advanced fibrosis and cirrhosis, but no markers were accurate enough for diagnosing metabolic dysfunction-associated steatohepatitis (MASH).
