Author: Tania Ahmed, Honorary Postdoctoral Associate, Macquarie University Astronomers have catalogued billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where these galaxies sit and trace how the universe changes over time. The universe also contains objects that are too faint, too far […]
When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict. But new research led by scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) shows that waves can behave very differently when they travel through a special class of materials. The […]
One of the most powerful ways to study the Universe is to map where galaxies are located. Galaxies are not scattered randomly through space; they gather into groups, clusters, filaments and other structures that trace the underlying distribution of dark matter. The pattern of this cosmic web carries information about the basic ingredients and history […]
Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange happens: The rules of quantum physics, which work so exquisitely for tiny atoms, seem to lose their grip as objects grow larger. Pondering where and how this shift from small-scale quantum fuzziness to everyday sharp certainty happens gives […]
Inactivation of tumor suppressor genes (TSGs) confers a cellular fitness advantage to human cancer cells, including in acute myeloid leukemia (AML), where it disrupts myeloid differentiation and promotes leukemogenesis. Loss-of-function mutations in TSGs are frequently observed in patients with hematologic malignancies , driving disease progression by blocking differentiation and enhancing self-renewal. Therefore, restoration of tumor […]
Water is H₂O. Few scientific formulas look more familiar, more compact, or more final. Two atoms of hydrogen, one of oxygen: the phrase seems to say what water really is beneath the shifting appearances of ice, vapour, rain, rivers and the liquid in a glass. Yet that little subscript was not easy to earn. By […]
Authors: Elisa Rigosi, Researcher in Sensory Biology, Department of Biology, Lund University and David O’Carroll, Professor of Sensory Biology, Department of Biology, Lund University One bee has long been regarded as a benchmark for visual performance: the honeybee drone. These male honeybees (Apis mellifera) have evolved highly specialised eyes for detecting queens during mating flights […]
A giant volcanic eruption acted a little like Vesuvius, but across an entire landscape in the Andes, burying the terrain beneath it and preserving information that would otherwise have been lost to erosion and deformation. Recently, the researchers looked at this vast expanse of volcanic rock that erupted from the Lauca Caldera in northern Chile […]

Nickel disulfide, NiS₂, is an unusual material. Its interior behaves as an electrical insulator, blocking the flow of current, while certain parts of its surface conduct electricity freely. This contradiction has puzzled physicists for decades, and a recent study offers a detailed explanation. The conduction, it turns out, is confined to tiny one-dimensional steps on […]
By 1800, water had already changed once. It was no longer one of nature’s simple terms, but a compound of hydrogen and oxygen (see Is Water H₂O? (1) From Element to Compound). The new chemistry had a powerful account of that change. What it still wanted was a more direct experiment: water itself, giving up […]
