The Eastern Pacific Ocean's Tropical Depression 9E formed on July 26 and by July 27 the depression had dissipated over 1,200 miles from Hilo, Hawaii. NASA's Terra satellite captured a look at the storm at its peak.

The Global Precipitation Measurement mission or GPM core satellite provided a rainfall and cloud analysis on powerful Typhoon Jongdari as it moves toward Japan. Jongdari follows another powerful typhoon that made landfall in Japan earlier this year.

Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, Shiqian Gao, University of Hong Kong, SAR China, gave an oral presentation titled "Silver Nitrate With Sodium Fluoride for Caries Arrest: 18-month Results." The IADR/PER General Session & Exhibition is in London, England at the ExCeL London Convention Center from July 25-28, 2018.

Water is vital for life.

But as our climate changes, the availability of water is also changing, leaving animals with limited or unreliable supplies of this critical resource.

It is more likely that you have seen a habu snake in a bottle of local rice liquor Awamori, in Okinawa, than that you've spotted one slithering by the wayside. Even so, habus are very common in the Ryukyu islands of which Okinawa is a part. Okinawa is home to three species of habu; the Okinawan habu (Protobothrops flavoviridis), endemic to the Ryukyu islands, is highly venomous.

An international team of materials scientists from France, Russia and Kazakhstan found a way to boost the efficiency of organic solar cells several times. The new study, published in the Journal of Materials Chemistry A, has shown that ordered structures based on organic molecules can be used to produce solar power.

Scientists have discovered that some treatments for cancer and sickle cell disease can destroy the germ cells that go on to develop into sperm in the testes of young boys. In some pre-pubescent boys, the treatment for sickle cell disease results in complete destruction of all their germ cells, which are called spermatogonia.

Study finds engineered rice lines with low stomatal density used just 60 per cent of the normal amount of water and were able to survive drought and high temperatures for longer than unaltered plants.

Almost half of the global rice crop derives from rain-fed agricultural systems where drought and high temperatures are predicted to become more frequent and damaging under climate change.

Rice cultivation is particularly water intensive - using an estimated 2,500 litres of water per kilogram.

Two years after a CIRES and CU Boulder team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they've uncovered tantalizing clues to the waves' origins. The interdisciplinary science team's work to understand the formation of "persistent gravity waves" promises to help researchers better understand connections between the layers of Earth's atmosphere--helping form a more complete understanding of air circulation around the world.

The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet's equator, scientists have found.

A study published in the journal Nature Communications found a chemical match between dust in the Martian atmosphere and the surface feature, called the Medusae Fossae Formation.
