Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter Array (ALMA), has produced the sharpest images ever of 24 debris disks, the dusty belts left after planets finish forming. These […]
Although science was not born in the seventeenth century (since the need for reliable information about the environment is intrinsic to any human society, and disciplines such as mathematics, astronomy, or biology had already flourished splendidly in Classical Antiquity), we cannot deny that around the year 1600 the history of humanity crossed a decisive threshold […]
Most of the electronic devices we use every day, from smartphones to solar panels, depend on electrons moving smoothly through crystal structures. In recent years, however, researchers have discovered that stacking extremely thin materials in carefully chosen ways can produce completely new types of behavior that never appear in ordinary bulk materials. One of the […]
Vincent van Gogh sliced off his ear with a knife during a psychotic episode. Ballet dancer Vaslav Nijinsky developed schizophrenia and spent the last 30 years of his life in hospital. Virginia Woolf lived with bipolar disorder, eventually taking her own life as she felt another deep depression beginning. Many famous creative artists have lived […]
Some 445 million years ago, life on Earth was forever changed. During the geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a sponge and giving an “icehouse climate” that, together with radically changed ocean chemistry, ultimately caused the extinction of about 85% of […]
A Radio-Frequency Quadrupole (RFQ) is a resonant cavity with a cylindrical symmetry divided in four lobes resembling a clover-like geometry and four vanes to focus and accelerate charged particles. This structure can accept a continuous flow of low-energy massive particles (such as protons or heavier ions) and accelerate them from the keV to the MeV […]
One of the most striking discoveries made by the James Webb Space Telescope, together with earlier observations from the Hubble Space Telescope, is that many galaxies in the young universe look very different from those we see around us today. Instead of graceful spiral disks or rounded ellipses, a large fraction of galaxies observed when […]
Author: Marika Taylor, Pro-vice-chancellor, Professor, University of Birmingham In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my PhD supervisor, predicted that a theory of everything – uniting the clashing branches of […]
The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest on intuition rather than clear definitions, and few attempts have been made to formally spell out what “simulation” even means. A new mathematical framework emerges A […]
T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy with a poor prognosis and limited options for targeted therapies . Since the targeted therapies benefiting T-ALL are still limited owing to the biological heterogeneity of T-ALL , identifying novel “druggable” molecular markers and illustrating the underlying mechanisms are immediate pressing issues in T-ALL […]
