The Director of the Department of Antiquities said the excavations took place under the building programme submitted by the Church of Cyprus, according to daily Politis.

The findings “include a Greek temple which is situated in the south eastern part of the complex and is enclosed by a courtyard. At the back of the temple there is a patio surrounded by different rooms,” Marina Solomonidou-Ierominidou said.

She added that “the complete excavation of the monument and the study of the findings, will allow the department to make more accurate deductions regarding this important monument”.

However, she said that the ancient findings will coexist with the building programme, ensuring that they will be protected and projected.

The Church of Cyprus is planning to build high-rises with luxury apartments, a 5-star hotel and an artificial island in the area of the findings.

In 2017, the Cabinet declassified the area from an Ancient monument schedule, to the surprise of the Department of Antiquities, which claimed that it was the first time that an area which was classified as an ancient monument is declassified while the excavations were still in progress.

«From this period there are large known mosques in Jerusalem and in Mecca, but here we have evidence of an ancient house of prayer, which seems to have served the farmers who lived in the area,» the authority said in a statement from the excavations’ directors, Jon Seligman and Shahar Zur.
It said no similar building had been found in the area where it was discovered. The authority was «examining possible ways in which this special finding can be integrated into the new neighbourhood,» it said.

Other finds in the area were a small settlement from the early Islamic period, the authority said. The Muslim conquest of the region occurred in the first half of the seventh century.

Hundreds of Viking artefacts discovered in northern Russia

The artefacts, including coins from faraway lands, beads, jewelry and other well-preserved man-made objects were found in an area of northern Russia believed to have served as a Viking trade hub in the tenth century AD.

After being discovered in 2016, the archaeological preserve near Gorozhane has become a major source of interest for archaeologists, with the remains of homes and hundreds of manmade objects, including Byzantine Imperial coins dating to the years 920-944, fragments of a pendant featuring a symbol of the Rurikid nobles of Kievan Rus, Dirham coins from ancient Arab caliphates, scale weights, arrowheads, horseshoe fasteners, and dozens of ancient human-made objects made of glass, stone, clay, ferrous and non-ferrous metals found at the site over the years.

Archaeologists believe the site, which dates back to at least the 10th century, once served as a hub for a trade route between Greece and the Varangians (the name for Vikings given by the Greeks and ancient Rus peoples). All the ancient objects found prior to the current dig were handed to the local archaeological center, with students from universities in Russia, Belarus and Estonia invited to take part in the expeditions with support from the Russian Historical Society.

Vikings began exploring in lands which are parts of the Baltic states, Russia, Belarus and Ukraine between the 6th and 9th centuries, traveling aboard their distinctive vessels along the Baltic, Black and Caspian Seas and conquering many local settlements amid efforts to open up trade routes with the Greeks and the Middle Eastern empires.

Most Varangians are believed to have assimilated with local Slavic tribes sometime after the 11th century. According to the ‘Primary Chronical’ history of Kievan Rus’, published in Kiev in 1113, a Varangian chieftain named Rurik became ruler (knyaz) of the city of Veliky Novgorod in 860, with his successors eventually expanding south to Kiev and founding the first East Slavic state, known as Kievan Rus.

Growing Guts

The prettiness of these coloured rings belies their serious practical potential. They’re fragments of small intestine that have been grown from stem cells in a laboratory. It’s hoped that such engineered tissues may one day be used to treat short bowel syndrome – a reduction in the length of functional bowel resulting from either surgical removal or disease. Premature babies with underdeveloped gastrointestinal tracts, for example, are prone to short bowel syndrome resulting from necrotising enterocolitis – a condition where parts of the intestine die. While intestinal transplants are one option for treating short bowel syndrome (and the consequent malnutrition), such surgeries come with a risk of transplant rejection. Growing intestine from a patient’s own stem cells avoids such risk and, encouragingly, advances in tissue engineering technology are enabling ever-larger pieces of intestine to be grown in culture. This once futuristic treatment idea is therefore becoming increasingly feasible.

Explanation: Why is the Cigar Galaxy billowing red smoke? M82, as this starburst galaxy is also known, was stirred up by a recent pass near large spiral galaxy M81. This doesn’t fully explain the source of the red-glowing outwardly expanding gas and dust, however. Evidence indicates that this gas and dust is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. The dust particles are thought to originate in M82’s interstellar medium and are actually similar in size to particles in cigar smoke. The featured photographic mosaic highlights a specific color of red light strongly emitted by ionized hydrogen gas, showing detailed filaments of this gas and dust. The filaments extend for over 10,000 light years. The 12-million light-year distant Cigar Galaxy is the brightest galaxy in the sky in infrared light, and can be seen in visible light with a small telescope towards the constellation of the Great Bear (Ursa Major).

What Does a Marsquake Look Like?

NASA — InSight Mission patch.

July 22, 2019

Southern California got all shook up after a set of recent quakes. But Earth isn’t the only place that experiences quakes: Both the Moon and Mars have them as well. NASA sent the first seismometer to the Moon 50 years ago, during the Apollo 11 mission; the agency’s InSight lander brought the first seismometer to Mars in late 2018, and it’s called the Seismic Experiment for Interior Structure (SEIS).

Provided by the French space agency, Centre National d’Études Spatiales (CNES), the seismometer detected its first marsquake on April 6, 2019. The InSight mission’s Marsquake Service, which monitors the data from SEIS, is led by Swiss research university ETH Zurich.

Quakes look and feel different depending on the material their seismic waves pass through. In a new video, scientists at ETH demonstrate this by using data from the Apollo-era seismometers on the Moon, two of the first quakes detected on Mars by SEIS and quakes recorded here on Earth.

By running data from these worlds through a quake simulator, or «shake room,» scientists can experience for themselves how different the earthquakes can be. Researchers had to amplify the marsquake signals by a factor of 10 million in order to make the quiet and distant tremors perceptible in comparison to the similarly amplified moonquakes and unamplified earthquakes.

Marsquake: How does it feel like?

A number of European partners, including France’s Centre National d’Études Spatiales (CNES) and the German Aerospace Center (DLR), are supporting the InSight mission. CNES provided the Seismic Experiment for Interior Structure (SEIS) instrument to NASA, with the principal investigator at IPGP (Institut de Physique du Globe de Paris). Significant contributions for SEIS came from IPGP; the Max Planck Institute for Solar System Research (MPS) in Germany; the Swiss Federal Institute of Technology (ETH Zurich) in Switzerland; Imperial College London and Oxford University in the United Kingdom; and JPL. DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, with significant contributions from the Space Research Center (CBK) of the Polish Academy of Sciences and Astronika in Poland. Spain’s Centro de Astrobiología (CAB) supplied the temperature and wind sensors.

Correcting historic sea surface temperature measurements

Something odd happened in the oceans in the early 20th century. The North Atlantic and Northeast Pacific appeared to warm twice as much as the global average while the Northwest Pacific cooled over several decades.

mystery about global climate change [Credit: Harvard]

Atmospheric and oceanic models have had trouble accounting for these differences in temperature changes, leading to a mystery in climate science: why did the oceans warm and cool at such different rates in the early 20th century?

Now, research from Harvard University and the UK’s National Oceanography Centre points to an answer both as mundane as a decimal point truncation and as complicated as global politics. Part history, part climate science, this research corrects decades of data and suggests that ocean warming occurred in a much more homogenous way.

Humans have been measuring and recording the sea surface temperature for centuries. Sea surface temperatures helped sailors verify their course, find their bearings, and predict stormy weather.

Until the 1960s, most sea surface temperature measurements were taken by dropping a bucket into the ocean and measuring the temperature of the water inside.

The National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation’s National Center for Atmospheric Research (NCAR) maintains a collection of sea surface temperature readings dating back to the early 19th Century. The database contains more than 155 million observations from fishing, merchant, research and navy ships from all over the world. These observations are vital to understanding changes in ocean surface temperature over time, both natural and anthropogenic. They are also a statistical nightmare.

How do you compare, for example, the measurements of a British Man-of-War from 1820 to a Japanese fishing vessel from 1920 to a U.S. Navy ship from 1950? How do you know what kind of buckets were used, and how much they were warmed by sunshine or cooled by evaporation while being sampled?

For example, a canvas bucket left on a deck for three minutes under typical weather conditions can cool by 0.5 degrees Celsius more than a wooden bucket measured under the same conditions. Given that global warming during the 20th Century was about 1 degree Celsius, the biases associated with different measurement protocols requires careful accounting.

«There are gigabytes of data in this database and every piece has a quirky story,» said Peter Huybers, Professor of Earth and Planetary Sciences and of Environmental Science and Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and senior author of the paper. «The data is rife with peculiarities.»

and North Atlantic (bottom). The blue line indicates the corrected data from this research. It shows greater
warming in the North Pacific and less warming in the North Atlantic relative to previous estimates

A lot of research has been done to identify and adjust for these peculiarities. In 2008, for example, researchers found that a 0.3-degree Celsius jump in sea surface temperatures in 1945 was the result of measurements taken from engine room intakes. Even with these corrections, however, the data is far from perfect and there are still unexplained changes in sea surface temperature.

In this research, Huybers and his colleagues proposed a comprehensive approach to correcting the data, using a new statistical technique that compares measurements taken by nearby ships.

«Our approach looks at the differences in sea surface temperature measurements from distinct groups of ships when they pass nearby, within 300 kilometers and two days of one another,» said Duo Chan, a graduate student in the Harvard Graduate School of Arts and Sciences and first author of the paper. «Using this approach, we found 17.8 million near crossings and identified some big biases in some groups.»

The researchers focused on data from 1908 to 1941, broken down by the country of origin of the ship and the «decks,» a term stemming from the fact that marine observations were stored using decks of punch cards. One deck includes observations from both Robert Falcon Scott’s and Ernest Shackleton’s voyages to the Antarctic.

«These data have made a long journey from the original logbooks to the modern archive and difficult choices were made to fit the available information onto punch cards or a manageable number of magnetic tape reels,» said Elizabeth Kent, a co-author from the UK National Oceanography Centre. «We now have both the methods and the computer power to reveal how those choices have affected the data, and also pick out biases due to variations in observing practice by different nations, bringing us closer to the real historical temperatures.»

The researchers found two new key causes of the warming discrepancies in the North Pacific and North Atlantic.

The first had to do with changes in Japanese records. Prior to 1932, most records of sea surface temperature from Japanese vessels in the North Pacific came from fishing vessels. This data, spread across several different decks, was originally recorded in whole-degrees Fahrenheit, then converted to Celsius, and finally rounded to tenths-of-a-degree.

respectively indicated by a two-letter code and deck number. GB stands for Great Britain; DE for Germany;
NL for the Netherlands; JP for Japan; RU for Russia [Credit: Duo Chan/Harvard]

However, in the lead-up to World War II, more and more Japanese readings came from naval ships. These data were stored in a different deck and when the U.S. Air Force digitized the collection, they truncated the data, chopping off the tenths-of-a-degree digits and recording the information in whole-degree Celsius.

Unrecognized effects of truncation largely explain the rapid cooling apparent in foregoing estimate of Pacific sea surface temperatures between 1935 and 1941, said Huybers. After correcting for the bias introduced by truncation, the warming in the Pacific is much more uniform.

While Japanese data holds the key to warming in the Pacific in the early 20th century, it’s German data that plays the most important role in understanding sea surface temperatures in the North Atlantic during the same time.

In the late 1920s, German ships began providing a majority of data in the North Atlantic. Most of these measurements are collected in one deck, which, when compared to nearby measurements, is significantly warmer. When adjusted, the warming in the North Atlantic becomes more gradual.

With these adjustments, the researchers found that rates of warming across the North Pacific and North Atlantic become much more similar and have a warming pattern closer to what would be expected from rising greenhouse gas concentrations. However, discrepancies still remain and the overall rate of warming found in the measurements is still faster than predicted by model simulations.

«Remaining mismatches highlight the importance of continuing to explore how the climate has been radiatively forced, the sensitivity of the climate, and its intrinsic variability. At the same time, we need to continue combing through the data—through data science, historical sleuthing, and a good physical understanding of the problem, I bet that additional interesting features will be uncovered,» said Huybers.

The research is published in Nature.

Protecting a forgotten treasure trove of biodiversity

The Cerrado is the largest savanna region in South America, but compared to the Amazon Forest to the North, it does not attract much attention. It is home to an incredible diversity of large mammal species including jaguar, the endangered maned wolf, the giant anteater, giant armadillo, and marsh deer, as well as more than 10,000 species of plants, almost half of which are found nowhere else on Earth. Despite its importance as a global biodiversity hotspot, it is one of the most threatened and over-exploited regions in Brazil. In fact, today, less than 20% of the Cerrado’s original area remains undisturbed and this habitat is at risk of conversion to agriculture, especially for soybean cultivation.

The region has been at the center of the country’s recent agricultural boom, with 48% of Brazil’s soybean production harvested in the Cerrado in 2015. Unlike the Amazon, where almost half of the area is under some sort of conservation protection, only 13% of the Cerrado is protected. Under Brazil’s Forest Code — an environmental law designed to protect the country’s native vegetation and regulate land use — 80% of the native vegetation on private lands in the Amazon biome has to be protected, but only 20% is required in the majority of the Cerrado. Between 2000 and 2014, almost 30% of the soy expansion in the Cerrado occurred at the expense of native vegetation. A similar proportion of soy expansion in the Amazon between 2004 and 2005 led to the implementation of the Amazon Soy Moratorium, which constitutes a zero-deforestation agreement between civil society, industry, and government that forbids the buying of soy grown on recently deforested land.
In their study, the team led by IIASA researcher Aline Soterroni and Fernando Ramos from Brazil’s National Institute for Space Research (INPE), endeavored to quantify the direct and indirect impacts of expanding the Amazon Soy Moratorium to the Cerrado biome in terms of avoided native vegetation conversion and consequent soybean production loss. Their findings indicate that expanding the moratorium to the Cerrado would prevent the direct conversion of 3.6 million hectares of native vegetation to soybeans between 2020 and 2050.

Accounting for leakage effects — in other words, the increase of native vegetation loss to other agricultural activities due to the expansion of soybeans over already cleared areas — the expanded moratorium would save 2.3 million hectares of the Cerrado. Nationally, this would require a reduction in soybean cultivation area of only around 2% (or 1 million hectares), as there are at least 25.4 million hectares of land that has already been cleared in the region (mainly for pasture areas with low productivity cattle ranching) that would be suitable for agricultural expansion. This suggests that both agricultural expansion and conservation of the remaining habitat may therefore be possible.

«According to our model, expanding the Amazon Soy Moratorium to the Cerrado can avoid the loss of a significant amount of native vegetation while simultaneously achieving soybean production goals. We also show that the Forest Code is not enough to protect the area given its low level of legal reserve requirements and its historical lack of enforcement,» explains Soterroni. «Our study presents the first quantitative analysis of expanding the soy moratorium from the Amazon to the Cerrado and could be used by traders and consumer markets to adjust their supply chains».

According to the researchers, a growing number of private sector actors are already voluntarily pledging to eliminate deforestation from their supply chains. Furthermore, consumer awareness of deforestation is increasing, providing companies with incentives to adhere to the responsible sourcing of commodities. Soterroni also points out that the close relative risks of future native vegetation conversion to soy estimated for China and the EU (37.52 and 37.06 hectares per 1,000 tons annually, respectively), shows that both of these entities can play an important role regarding the responsible sourcing of soy.

To preserve the biodiversity and ecosystem services provided by the remaining parts of the Cerrado, urgent action is needed. Soterroni says that to this end, a public-private policy mix would be essential to preserve the last remnants of the region and in light of the recent absence of strong environmental governance in Brazil, the expansion of the Soy Moratorium beyond the Amazon to the Cerrado might be more urgent than previously thought. The researchers urge the EU and stakeholders from other regions to encourage the expansion of conservation measures to the Cerrado and to support the call for making soy trade with Brazil more sustainable.

The study is published in Science Advances.
