In the Temple of Khnum at Esna, Upper Egypt, German and Egyptian researchers have uncovered a series of vibrantly-colored ceiling frescoes. The relief images in the central section of the ceiling, Professor Christian Leitz from the University of Tübingen reports, make up a total of 46 depictions of the Upper-Egyptian vulture goddess Nekhbet and the Lower-Egyptian serpent goddess Wadjet. Both are depicted as vultures with outspread wings. While Nekhbet bears the head of a vulture and the white crown of Upper Egypt... Читать дальше...

Vibrant coral reefs teeming with marine life are diminishing throughout the Caribbean as global temperatures rise. Coral reefs are habitats that support the seafood industry, are barriers for coastal communities from storms, flooding and sea level rise, and are attractions for tourism. Their net economic value worldwide is estimated to be tens of billions of dollars. However, if atmospheric and ocean temperatures continue to rise at the current pace, coral reefs face extinction within the next 80 years, or by the end of this century.

A new research paper published in Aging Volume 14, Issue 9, is titled "Single-cell transcriptomics reveals age-resistant maintenance of cell identities, stem cell compartments and differentiation trajectories in long-lived naked mole-rats skin."

Compact and lightweight metasurfaces—which use specifically designed and patterned nanostructures on a flat surface to focus, shape and control light—are a promising technology for wearable applications, especially virtual and augmented reality systems. Today, research teams painstakingly design the specific pattern of nanostructures on the surface to achieve the desired function of the lens, whether that be resolving nanoscale features, simultaneously producing several depth-perceiving images or focusing light regardless of polarization.

Zoning laws, adopted by thousands of local governments across the country, dictate much of what can be built in the United States. Zoning codes have major ramifications for businesses, housing, and quality of life but can be very difficult for non-experts to understand.

X-ray detection is of great importance in diverse applications, such as radiation detection, medical diagnosis, and security inspection. A popular way to achieve X-ray detection is to integrate a photodetector with a luminescent material called a scintillator, which emits energy in the form of light. Scintillators can convert high-energy X-ray photons to low-energy visible luminescence.

Researchers have developed a new metasurface-based device that can produce multiple distinct holographic images depending on the surrounding medium and the wavelength of light used. The ability to store information that is only retrievable with the right set of keys—such as a certain light wavelength combined with wet conditions—could be further developed to design simple yet effective encryption devices.

Covered in the red dust that sealed its fate, the NASA InSight lander is slowly shutting down, more than 250 million kilometers from home.

Agencies that rate and rank nations, corporations and colleges wield enormous power, influencing investment flows and prompting leaders to pursue policies that might improve their standing.

Early animals formed complex ecological communities more than 550 million years ago, setting the evolutionary stage for the Cambrian explosion, according to a study by Rebecca Eden, Emily Mitchell, and colleagues at the University of Cambridge, UK, publishing May 17th in the open-access journal PLOS Biology.

As part of a government effort to reduce animal testing, researchers at the National Institute of Standards and Technology (NIST) have worked with the Consumer Product Safety Commission (CPSC) and Inotiv Inc. to produce a new protocol for screening skin allergens. The method is potentially cheaper and faster than animal testing, while maintaining a similar performance.

For many years after discovering a diverse population of sometimes dangerous microbes constantly living in our intestines, scientists described the situation as a form of living with the enemy. But when it comes to commensal populations of the fungus Candida albicans, the dreaded invader may be better seen as a helpful friend arriving with gifts.

If you have ever watched a bird land on a tree branch, you may have noticed that it rapidly pitches its wings upward at a high angle to execute a smooth landing. However, for some birds, they land by folding their wings as they perch instead, creating a sweeping motion as they decelerate.

Removing not only a diseased grapevine but the two vines on either side of it can reduce the incidence of leafroll disease, a long-standing bane of vineyards around the world, Cornell researchers have found.

Physicists at EPFL, within a large European collaboration, have revised one of the fundamental laws that has been foundational to plasma and fusion research for over three decades, even governing the design of megaprojects like ITER. The update shows that we can actually safely use more hydrogen fuel in fusion reactors, and therefore obtain more energy than previously thought.

When Hurricane Michael tore through North Florida in 2018 as a Category 5 storm, it left more than 3 million acres of felled trees in its wake.

Meet Freeway. He's a teenage mischief maker, a land-loving sea lion fishing for freedom.

In South Korea, which relies on imports for 99.3% of its metal resources, the per capita consumption of those metal resources is the highest in the Organization for Economic Co-operation and Development, and consumption of precious metals in industries such as renewable energy, healthcare and semiconductors is increasing. Gold is in demand for applications such as batteries, electric vehicles and renewable energy in the electric and electronic industries, but is a big variable in the industry due to its limited availability and high cost.

Twenty million years ago, the Swiss Plateau region, or Mittelland, was an ocean in which dolphins swam. Researchers at the University of Zurich's Paleontological Institute have now discovered two previously unknown species related to modern sperm whales and oceanic dolphins, which they identified based on ear bones.

As early as 9,500 years ago, people in Europe used slash-and-burn methods to make land usable for agriculture. This is shown by environmental data generated by scientists from the Senckenberg Center for Human Evolution and Paleoenvironment (S-HEP) at the University of Tübingen on the basis of two drill cores from the Ammer Valley. The data were then correlated with results from the Mesolithic scattered finds from Rottenburg-Siebenlinden excavated by the Baden-Wuerttemberg Landesamt für Denkmalpflege (State Office for Monument Preservation).

President Xi of China announced in September 2020 that China will "aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060." Although it is essential to reduce CO2 emissions from energy consumption, which accounts for more than 85% of the total annual CO2 emission in China, the role of terrestrial carbon sequestration cannot be underestimated in carbon neutrality.

Like storm waves battering a ship, new versions of the SARS-CoV-2 virus have buffeted the world one after another. Recently, scientists keeping tabs on these variants noticed a trend: Many carry the same set of three mutations. In a new study in ACS' Biochemistry, researchers examined how these mutations change the way a key piece of the virus functions. Their experiments show how this triad alters traits it needs to cause and sustain COVID-19 infection.

A Diverfarming project study compares the environmental footprint and the economic performance of traditional mandarin monocropping as opposed to growing mandarin intercropped with herbaceous crops and the use of deficit irrigation

Southwestern China (SWC) is a region on the southeastern side of the Tibetan Plateau, in which both southwesterly and southeasterly winds influence weather patterns during the summer monsoon period. Spring drought before the onset of the summer rainy season is common throughout SWC, which threatens local ecology, agriculture, and economic balance.
