Measurement

A group of international scientists, including an Australian astrophysicist, has used know-how from gravitational-wave astronomy (used to find black holes in space) to study ancient marine fossils as a predictor of climate change. The research, published in the journal Climate of the Past, is a u

You can see it in the airlines removing scheduled flights, factories cancelling shifts, restaurants closing again and movie theatres shuttering once more.

Scientists from Osaka University, The University of Queensland, and the Faculty of Engineering at the National University of Singapore have created polymer-coated nanodiamonds that can be absorbed into cells. Based on changes in their fluorescence properties, the internal thermal conductivity of the cell can be measured, which may lead to new heat treatments that attack cancer cells.

A keen sense of smell is a powerful ability shared by many organisms. However, it has proven difficult to replicate by artificial means. Researchers combined biological and engineered elements to create what is known as a biohybrid component. Their volatile organic compound sensor can effectively detect odors in gaseous form. They hope to refine the concept for use in medical diagnosis and the detection of…

Researchers from the Moscow Institute of Physics and Technology (MIPT) have developed a prototype detector of solar particles. The device is capable of picking up protons at kinetic energies between 10 and 100 megaelectronvolts, and electrons at 1-10 MeV. This covers most of the high-energy particle

World timekeepers have decreed there will be no leap second on December 31, 2020.

And they may not even be seeing the whole thing.

Understanding the stellar population of our galaxy could reveal a great deal, not only about our own home but also about the universe as a whole. So-called galactic archaeology can reveal how galaxies take shape, and explain some of the interesting complexities of our own. Of course, given our location inside it, the Milky Way is also the best laboratory we have to study the intricacies of how galaxies evolve,…

Our Milky Way is not alone in the universe. Surrounding us are numerous satellite galaxies, taking part in a continuous grand dance. But how do these neighbouring galaxies behave, how do they interact with our galaxy, and what does the future hold for them?

The positively charged protons in atomic nuclei should actually repel each other, and yet even heavy nuclei with many protons and neutrons stick together. The so-called strong interaction is responsible for this. Scientists have now developed a method to precisely measure the strong interaction utilizing particle collisions in the ALICE experiment at CERN in Geneva.

In new step toward quantum tech, scientists synthesize 'bright' quantum bits  Science Codex

The night sky will appear completely different half a million years from now. Researchers figured out what it'll look like.

Columbia team discovers 6-nanometer-long single-molecule circuit with enormous on/off ratio due to quantum interference; finding could enable faster, smaller, and more energy-efficient devices. Researchers, led by Columbia Engineering Professor Latha Venkataraman, report today that they have disc

Researchers are becoming increasingly critical of some brain scan studies using fMRI machines that purport to show how our minds shape our behavior.

The motion of stars in the outskirts of our galaxy hints at significant changes in the history of the Milky Way. This and other equally fascinating results come from a set of papers that demonstrate the quality of ESA's Gaia Early third Data Release (EDR3), which is made public on December 3, 2020.

The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb or reflect light and thus cannot be directly observed using any existing instruments.

As a vehicle travels through space at hypersonic speeds, the gases surrounding it generate heat at dangerous temperatures for the pilot and instrumentation inside. Designing a vehicle that can drive the heat away requires an understanding of the thermal properties of the materials used to construct it. A recent two-part study at the University of Illinois Urbana-Champaign developed a method to create 3-D models of…

The Borexino collaboration, in which also scientists from TU Dresden are involved, has succeeded after more than 80 years in experimentally confirming the Bethe-Weizsäcker cycle. Stars produce their energy through nuclear fusion by converting hydrogen into helium — a process known to researchers as

Scientists have detected neutrinos formed during a largely mysterious process in the Sun, in what they are hailing as a major breakthrough.

Based on genome-wide experiments, the human body has 2,064 genes relevant to COVID-19. So why are researchers only studying 611 of them?
