104-1 Week 5: 火星發現液態水

Nasa briefing: 'Liquid water on Mars'

28 September 2015

Scientists think they can now tie dark streaks(條紋) seen on the surface(表面) of Mars to periodic flows of liquid water.

Data from a Nasa satellite(人工衛星) shows the features, which appear on slopes(斜坡), to be associated with salt deposits(鹽類沉積).

Crucially, such salts could alter(替換) the freezing(冷凍) and vaporization(蒸發) points of water in Mars's sparse air, keeping it in a fluid(流體) state long enough to move.

Michael Meyer, the lead scientist on Nasa's Mars exploration programmed, and Dr Jim Green, Nasa's planetary science director, made the announcement.

"Under certain circumstances(情況), liquid water has been found on Mars," Dr Green said.

104-1 Week 4: 登革熱

Tainan City Dengue Cases Top 20,000

Posted by Robert Herriman on October 17, 2015 // 1 Comment

With an additional 183 dengue(登革熱) fever cases report Friday in Taiwan’s southern city of Tainan, the dengue tally has topped the 20,000 mark putting the total at 20,172 as of Oct. 16.

Although Tainan City hit this unfortunate landmark, the good news is the cases appear to be tapering off(逐漸停止) somewhat. The 183 cases reported yesterday was 16 less than the previous Friday, health officials note.

A total of 367 new cases were reported countrywide(全國的) yesterday, bringing the total to 24,874.

While things appear a little better in Tainan, neighboring Kaohsiung City is seeing a small increase in cases compared to last week. The total in Kaohsiung now stands at 4,274.

According to the Taiwan CDC, 106 dengue-related fatalities(災禍) have been reported since the beginning of the outbreak in May.

Dengue fever is an infectious disease carried by mosquitoes and caused by any of four related dengue viruses. This disease was once called called “break-bone fever” because it sometimes causes severe(嚴重的) joint(關節) and muscle pain that feels like bones are breaking.

Dengue fever of multiple types is found in most countries of the tropics and subtropics particularly during and after rainy season.

There are four types of dengue virus: DEN-1, DEN-2, DEN-3 and DEN-4.

People get the dengue virus from the bite of an infected Aedes mosquito. It is not contagious(傳染性的) from person to person.

There are three types of dengue fever in order of less severe to most: the typical uncomplicated(不複雜的) dengue fever, dengue hemorrhagic(出血性的) fever (DHS) and dengue shock syndrome(併發症) (DSS).
