Archaeological evidence that a late 14th-century tsunami devastated the coast of northern Sumatra

A team of researchers with members from Singapore, Indonesia, Ireland and the U.K. has found more evidence of a tsunami approximately 600 years ago that destroyed communities in the same part of Sumatra as the 2004 tsunami.

In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of gravestones and pottery in the area and what they found. The Indian Ocean tsunami of 2004 was devastating, killing over 280,000 people and displacing millions.

The tsunami was caused by an earthquake just off the coast of Sumatra, one of the islands that make up Indonesia. One of the hardest-hit areas was the province of Aceh, fatalities there were approximately 160,000.

In this new effort, the researchers have found more evidence of a similar tsunami striking the same region in 1394. Geologic evidence uncovered after the 2004 tsunami showed that there had been another tsunami 600 years earlier, but there was little evidence indicating how powerful or devastating it had been.

The work by the new team began when one of its members came across several Muslim gravestones that had been uncovered by the 2004 tsunami. The researchers began searching in earnest for other evidence of people living in the area before and after the earlier tsunami.

The researchers report that they found evidence of 10 settlements in the area, nine of which had been completely destroyed by the 1394 tsunami. The 10th settlement was on a hilltop beyond the reach of the giant waves. Study of ceramics from the period showed the destroyed communities dated back to the 11th and 12th centuries.

Study of the surviving settlement showed that the ceramics in the area from that time period came from as far away as Syria and China. It, too, suffered from the tsunami, however, as it went into decline after the tsunami.

The researchers also found evidence that showed Muslim traders moving in to establish new communities where the old ones had stood. The researchers believe these people eventually established an Islamic kingdom known as the Aceh Sultanate.

They further suggest that studies like theirs could provide more information regarding what happens to regions that are destroyed by tsunamis.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Pohpohan (Pilea melastomoides)

Pohpohan clearweed ( Pilea melastomoides ) is a species of plant in the Urticaceae, herbaceous perennial, erect stems, up to 100 cm tall, succulent, square or cylindrical, enlarged in the middle of the internodes, bright green in color and forming colonies in the shade. P. melastomoides has stipules that are immediately deciduous or subpersistent, green or brownish and oblong. The stalk is 2-9 cm long. The leaf blade is ovate or ovate-elliptic or oblong-lanceolate. The surface is wavy, pale green on the underside, dark green on the top. The three main veins are central and linear. Rounded base, tapered ends and serrated edges. The inflorescences are paired, the male is a dense cyme paniculata.

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...
