A 3,400-year-old city emerges from the Tigris River
A team of German and Kurdish archaeologists have uncovered a 3,400-year-old Mittani Empire-era city once located on the Tigris River. The settlement emerged from the waters of the Mosul reservoir early this year as water levels fell rapidly due to extreme drought in Iraq. The extensive city with a palace and several large buildings could be ancient Zakhiku—believed to have been an important center

Antarctica's only active volcano shows how CO2 allows volcanoes to form persistent lava lakes at the surface
Antarctica has long been a land of mystery and heroic feats made famous by the explorations of James Ross, Roald Amundsen, Robert Scott and Ernest Shackleton. A key piece of the puzzle for understanding global continental evolution, Antarctica contains examples that define the spectrum of Earth's volcanic processes. Now, a joint University of Utah and University of Canterbury New Zealand study sho

Chip-scale Floquet topological insulators to enhance 5G wireless communications
Floquet topological insulators are materials with topological phases that originate from tailored time-dependent perturbations of their crystal structure. These materials have been proved to feature highly unusual electron conduction properties. In recent years, there has been significant interest in exploring analogous features for electromagnetic waves using tailored metamaterials, which promise

Astrophysicists simulate a fuzzy dark matter galactic halo
Dark matter is a type of matter in the universe that does not absorb, reflect or emit light, which makes it impossible to directly detect. In recent years, astrophysicists and cosmologists worldwide have been trying to indirectly detect this elusive type of matter, to better understand its unique features and composition.

Plastic Recycling Doesn't Work and Will Never Work
Americans support recycling. We do too. But although some materials can be effectively recycled and safely made from recycled content, plastics cannot. Plastic recycling does not work and will never work. The United States in 2021 had a dismal recycling rate of about 5 percent for post-consumer plastic waste, down from a high of 9.5 percent in 2014, when the U.S. exported millions of tons of plas

'It's Extremely Important That We Don't Forget the Brutality'
T he Western world must prepare itself for a long war in Ukraine that will require ongoing support for Kyiv to guarantee Russia's defeat, as well as reinforced defenses across Europe to ensure that Vladimir Putin does not underestimate NATO's readiness to defend "every inch" of its territory, Jens Stoltenberg, the military alliance's secretary-general, told me recently.

China Launching Three Astronauts As It Expands Its Space Station
Tiangong China might be sending three of its astronauts into space as soon as the first week of June. Yesterday's SpaceNews report said that the Long March 2F rocket was rolled out slowly to the pad at Jiuquan Satellite Launch Center on Sunday. The rocket had been on standby for just shy of a year in case it was needed for an emergency mission to the country's space station, and the three crew me

How censoring China's open-source coders might backfire

Later that day, Gitee released a statement explaining that the locked code was being manually reviewed, as all open-source code would need to be before

They Were Reckless and in Love, and They Were the New Hollywood

Understanding gender dysphoria in transgender teenagers
The teenage years are a tumultuous time in one's life, especially for transgender teens. On top of typical social, mental, physical and emotional changes, they might also experience gender dysphoria—the psychological distress caused by a mismatch between a person's assigned sex and gender identity. Also, unlike adults, transgender teenagers might not have access to treatments like surgery or hormo

Nanoengineers boost signals from fluorescent sensors
Fluorescent sensors, which can be used to label and image a wide variety of molecules, offer a unique glimpse inside living cells. However, they typically can only be used in cells grown in a lab dish or in tissues close to the surface of the body, because their signal is lost when they are implanted too deeply.

Light-triggered multifunctional nanoplatform for efficient cancer photo-immunotherapy
Cancer immunotherapy is a treatment modality against tumor growth and metastasis via stimulating host immune responses. Phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), is a less invasive treatment compared to chemotherapy. To be specific, PDT and PTT-induced immunogenic cell death can release tumor-associated antigens and damage-associated molecular patterns, sti

Fjords emit as much methane as all the deep oceans globally
During heavy storms, the normally stratified layers of water in ocean fjords get mixed, which leads to oxygenation of the fjord floor. But these storm events also result in a spike in methane emissions from fjords to the atmosphere. Researchers have estimated that the total emissions of this climate-warming gas are as great from fjords as from all the deep ocean areas in the world put together.

Cooperative molecular networks may have been the spark of life on other planets
Darwin's theory of evolution probably isn't the full explanation for the emergence of life. Even in a barren environment conducive to fierce competition, cooperation between molecular networks may have spawned life on Earth and, by extension, elsewhere in the universe. And molecular cooperation may occur much more readily than expected in nature.

Strong gap between motivation to act green and the impact of clothing consumption

Coherent oscillation between phonons and magnons
Two different waves with the same frequency and wavelengths can be coupled, so that the amplitude alternates periodically between the two to form a phenomenon known as a coherent beating oscillation.

Solids too can equally maintain va

Researchers realize efficient hydrogen-peroxide production in acid
As one of the 100 most important chemicals in the world, hydrogen peroxide (H2O2) is mainly produced by the energy- and waste-intensive anthraquinone oxidation (AO) method.

Seeing the intrinsic emission from a single natural protein with ultraviolet optical antennas

Key insights into a protein linked to diabetes and hypertension
The amount of salt and water in our cells and their pH is strictly controlled for cell survival. To maintain the necessary balance, special proteins perform the essential role of exchanging protons (hydrogen ions, or H+) for sodium (Na+) or lithium (Li+) ions across cell membranes. These proteins are called sodium-proton exchangers (Na+/H+ exchangers, or NHEs). Found in every cell, NHEs tightly re

Observation of an intermediate state during lithium intercalation of twisted bilayer MoS2
Nature Communications, Published online: 30 May 2022; doi:10.1038/s41467-022-30516-z Li intercalation of MoS2 induces a transition from the insulating H-phase to the metallic T-phase, with a sharp boundary in between. Here the authors stabilize the intermediate phase in twisted bilayer MoS2, by leveraging the Moiré potential which facilitates fast Li diffusion and uniform intercalation.
