How Hong Kong can keep the talking going when US-China officials don’t

When Tung Chee-hwa died, the obituaries predictably described a Hong Kong shipping mogul who became the city’s first postcolonial chief executive. How his government navigated the Asian financial crisis and severe acute respiratory syndrome (Sars) epidemic and its retreat from Article 23 were highlighted. There was less attention paid to the political hybrid he embodied. Tung sat as vice-chairman of China’s top political advisory body, the Chinese People’s Political Consultative Conference,...

Most accurate cosmic clocks show unexpected instability

In all the cosmos, pulsars are the most precise long-term way to measure time. The rate of orbital decay of a binary pulsar is highly dependent on the speed of gravity and the orbital parameters of the binary system. We have used binary pulsar data to constrain the speed of gravity to be equal to the speed of light to a precision of 99.8%, and to infer the existence of gravitational waves decades before LIGO and Virgo detected them. Here, double pulsar J0737-3039 is illustrated, with the observed relativistic time delay shown at right. Credits : M. Kremer/MPIfRA Each time these magnetized…

Stem cells reverse stroke damage and restore movement in mice

Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.

[Correspondence] Multicancer detection tests: holy grail or cautionary tale?

A single blood test that can identify most cancers remains the aspirational goal of cancer screening. The US biotechnology company Grail has been closest to developing a viable multicancer detection test. In June, 2026, the high hopes of many were dashed at the annual American Society of Clinical Oncology (ASCO) scientific meeting: Grail's landmark Galleri trial, which randomly assigned 140 000 UK residents to usual care plus multicancer detection testing versus usual care alone, failed to meet its primary endpoint—a reduction in late-stage cancers.

[Comment] The arts belong at the heart of health policy

As Chile's Minister of Health from 2000 to 2002, I ran a public network that shortened waiting lists and expanded primary care, although it could not repair what fear, isolation, and broken trust do to a population. As the first female President in my country (2006–10 and 2014–18), I signed into law the Ministry of Cultures, the Arts, and Heritage, giving Chile's cultural life its first cabinet-level home. These experiences taught me that a country's cultural life and its health are the same project, seen from two angles.
