In the 1930s, the Soviet Union built a series of submarines called the S class, based on German designs.
In the summer of 1942, the S7 sank the Swedish cargo ships Margareta and Luleå, delivering iron to Germany. Shortly after, the sub was cruising on the surface at night, off the Swedish coast not far from Norrtälje, when she was spotted by the Finnish submarine Vesihiisi. The Vesihiisi fired one torpedo and the S7 sank quickly.
Researchers believe this quality could be harnessed to help slow the spread of diseases such as cancer.
Potentially, it could lead to a new generation of drug treatments.
The Australian team found that shark antibodies can withstand high temperatures as well as extremely acidic or alkaline conditions.
Tallen, my youngest daughter and part-time dive buddy entered the cool emerald coloured water with me as the current slowed to a stop to change direction (slack). Full of anticipation, Tallen and I descended down the southwest side of Virago Rock within Porlier Pass, a .65 km (.4 mile) wide channel between the islands of Valdez and Galiano.
Sea Hunters, L.P., a division of the Portland Maine based shipwreck research and recovery company Sub Sea Research, embark to recover of one of the world's wealthiest wrecks.
It was reported that the wreck of the Port Nicholson was discovered in 2008 by Greg Brooks, of the American company Sub Sea Research, but the discovery was kept secret until February 2012.
Brooks initially claimed to be investigating an unidentified vessel, codenamed Blue Baron, that lay off the coast of Guyana in South America.
The vessel's hull, constructed without iron nails, is 16 m (52 feet) long, 5 m (16 feet) wide and 4 m (13 feet) deep. There is a hole in the right side of the hull and divers believe the ship sank during a storm.
They also discovered suspected human remains.
The expedition to the depths of the world's deepest and oldest lake was organized to search for historic artefacts linked with the Krugobaikal Railway, which saw numerous train crashes in the 19th century.
If that age is accurate, the skeleton, Dubbed Eva de Naharon, or Eve of Naharon, —along with three others found in underwater caves along the Caribbean coast of the Yucatán Peninsula —would be the oldest human skeleton ever found in the Americas
The three other skeletons excavated in the caves have been given a date range of 11,000 to 14,000 years ago, based on radiocarbon dating. The finds could provide new clues to how the Americas were first populated.
The submarine was reported lost Aug. 16, 1942. Underwater video footage captured by an expedition hired by sons of the commanding officer, Lt. Cmdr. Mannert L. Abele, allowed the Navy to confirm the discovery.
Japanese anti-submarine attack data recorded no attack in the Aleutian area at the time of the Grunion's disappearance, so the submarine's fate remained an unsolved mystery for more than 60 years, the US Navy said.
The British submarine HMS Olympus, sank in 1942 at the height of the siege of Malta and is one of the most historic wrecks off the coast of this island.
The discovery of the wreck completes a historic and tragic story. During the height of the German and Italian blockade of Malta, the British Navy fought a constant battle to keep the valiant Island supplied with food, fuel and war supplies. Submarines were an essential part of this operation, both in bringing in supplies and defending the merchant shipping.
The minute scales, which are just 200 micrometres long, are made from tough enamel, such as that found on teeth, giving the skin a rough texture like sandpaper. Lying flat, they had previously been found to reduce drag as the shark swims. Some reports had also suggested that sharks can bristle their scales, causing them to stand up on end.
Experiments have now revealed that tiny vortices or whirlpools formed within the cavities between the scales.
Howard Schatz is an extraordinary photographer who captures the ethereal fluidity of the human body under water. A dazzling array of his underwater studies are now compiled in a new book entitled, H2O. Gunild Symes caught up with the effervescent Schatz to gain some insight into the stunning imagery found within the pages.
Canadian artist, Micheline Lamarre Hadjis, loves color. Her paintings are rich with vibrant hues. The images draw the viewer into another world where light and shadow, contrast and form burst from the canvas with vitality and luminosity.
