Strangers in their own land: Mexicans deported from Trump’s America find refuge in ‘Little LA’

With plentiful jobs and community support, one Mexico City neighbourhood has become a haven for those who have lived much of their lives in the US With its wide avenues lined with tall palm trees, its quaint cafes and old-school cantinas, as well as the mix of English and Spanish spoken on the street, the Tabacalera neighborhood in downtown Mexico City has a certain US feel – so much so that it is has become known as Little LA . The nickname is about more than appearances, however. In recent years, this corner of the metropolis has become a haven for many Mexicans deported from the US,…

Why Chinese foreign minister’s trip to South Korea ‘dealt a low blow’ to Seoul

China’s top diplomat, Wang Yi, concluded his visit to South Korea on Friday, but declined to back Seoul’s push for multiparty peace talks involving the North. His two‑day trip, which followed President Xi Jinping’s first visit to Pyongyang in seven years in June, coincided with US President Donald Trump’s decision to scale back joint military exercises with South Korea and call for further talks with the North. North Korea, however, responded with more than 10 short-range ballistic missile...

China and US push Southeast Asia over their AI blocs. Will it test region’s non-alignment?

Southeast Asian leaders have long insisted they will not be forced to pick sides in the great-power rivalry between the US and China. But their posture is about to be further tested. This time, the battleground is AI. While Washington wants the region locked into Pax Silica – its bid to build a China-free artificial intelligence supply chain – Beijing wants its neighbours to join China’s own World Artificial Intelligence Cooperation Organisation (Waico). Sources told the South China Morning Post...

China ha construido un “autobús escolar” vertical: un ascensor de 288 metros para niños que antes escalaban hasta clase

Cuando pensamos en las grandes infraestructuras de China, es habitual imaginar obras construidas para cambiar la escala de un país entero: la presa de las Tres Gargantas , una de las mayores centrales hidroeléctricas del mundo; o proyectos urbanos como la Nueva Área de Xiong'an , un nuevo polo urbano diseñado cerca de Pekín para concentrar nuevas funciones económicas y tecnológicas. Pero junto a esos grandes proyectos existe otra clase de ingeniería menos llamativa por sus dimensiones y mucho más cercana por su impacto: infraestructuras diseñadas para resolver problemas concretos de…

Portugal busca agua donde parece imposible: su nueva desaladora convertirá agua del mar en millones de litros para el Algarve

Si alguna vez hemos recorrido la costa del Algarve, probablemente la imagen que nos viene a la cabeza sea la de sus playas entre acantilados dorados, pequeñas calas protegidas por la roca, aguas atlánticas y un clima que ha convertido esta región del sur de Portugal en uno de los grandes destinos turísticos europeos. Pero detrás de ese paisaje existe un problema menos visible: garantizar que haya suficiente agua en una zona donde las sequías prolongadas y la presión sobre los recursos disponibles han obligado a buscar nuevas soluciones. La respuesta que Portugal ha puesto sobre la mesa es la…

3 minutes of sprinting does something 90 minutes of exercise does not

A few minutes of sprinting may reshape the bloodstream far more dramatically than a much longer moderate workout. Six 30-second sprints altered nearly a quarter of the blood proteins measured and more than 200 metabolites, while 90 minutes of moderate cycling produced far smaller immediate changes. Many of the proteins affected by sprinting were also associated with lower risks of obesity, type 2 diabetes, and other metabolic diseases.

This weight-loss hormone may protect the liver even without weight loss

A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found that GDF15 activates a previously unknown brain-to-liver pathway that triggers the release of glucocorticoids, helping calm immune activity in the liver.

AI may know how you’ll respond to a vaccine before you get it

AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune readiness” that helped distinguish strong responders from weak ones. Surprisingly, even some healthy people responded poorly, while some immunosuppressed people mounted strong responses.

[Comment] Expanding regulatory T cells to treat atopic dermatitis

Atopic dermatitis remains one of the most burdensome inflammatory skin diseases worldwide, with a substantial effect on quality of life, sleep, mental health, and health-care use. Its population-level effect has been highlighted by the Global Burden of Disease Study analyses, in which atopic dermatitis ranks among the leading skin diseases by disability-adjusted life-years.1 Over the past decade, treatment has changed markedly. Biologics targeting type 2 inflammation and oral Janus kinase (JAK) inhibitors have expanded the therapeutic armamentarium, yet a relevant proportion of patients with…

[Articles] Rezpegaldesleukin treatment of moderate-to-severe atopic dermatitis (REZOLVE-AD): final results from the 16-week induction period of an international, double-blind, placebo-controlled, randomised phase 2b study

Over the 16-week induction period, rezpegaldesleukin treatment resulted in significant and clinically meaningful improvements across multiple clinical endpoints, including the primary endpoint of EASI percentage change from baseline, in comparison with placebo. Rezpegaldesleukin had a clinically favourable adverse event profile in adult patients with moderate-to-severe atopic dermatitis, supporting its further development as a novel Treg-enhancing biological treatment.
