The Tropical Rainfall Measuring Mission or TRMM satellite had a look at tropical cyclone Guito in the Mozambique Channel on February 18, 2014 at 1525 UTC/10:25 a.m. EST. The early evening (local time) view occurred only about three hours after Guito attained tropical storm intensity of 35 knots/40 mph/62 kph).
This visible image from NASA's Terra satellite on Feb. 20 at 0800 UTC shows that Cyclone Guito has moved south in the Mozambique Channel, and its western fringes were brushing over Mozambique.

TRMM's Microwave Imager (TMI) had better coverage of Guito than the Precipitation Radar (PR) instrument whose swath was well to the south of the tropical cyclone's center of circulation. TRMM TMI revealed that Guito was producing rain at a rate of over 50mm/~ 2 inches per hour in the center of the Mozambique Channel and scattered light rain on Madagascar's western coast.
At NASA's Goddard Space Flight Center in Greenbelt, Md. a rainfall anomaly analysis was made by comparing rainfall data compiled during the twelve year period from 2001-2012 to "near real-time" Multi-satellite Precipitation Analysis data collected for the same period. That analysis showed that rainfall in the northern Mozambique Channel has been above normal for the past month.
These rainfall estimates were used to create a simulated 3-D perspective view with higher precipitation amounts appearing to be taller than lower amounts. The highest totals, with amounts in the Mozambique Channel greater than 430 mm/~16.9 inches.
On Feb. 20 at 0800 UTC/3:00 a.m. EST, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite showed that Cyclone Guito had moved farther south in the Mozambique Channel that the previous day. The MODIS image also showed that Guito's western fringes were brushing over Mozambique. In addition, multispectral satellite imagery showed that the strong convection associated with the low-level center of circulation had decreased.
At 0900 UTC/4:00 a.m. EST, Guito was in the southern Mozambique Channel near 25.3 south latitude and 38.6 east longitude. That puts Guito's center over 575 nautical miles from the Capital city of Antananarivo, Madagascar. Guito's maximum sustained winds were near 65 knots/74.5 mph/120.4 kph (hurricane-force). It was moving to the south at 13 knots/14.9 mph/24.0 kph.
Guito is heading southeast and out of the Mozambique Channel and into the open waters of the Southern Indian Ocean. The Joint Typhoon Warning Center or JTWC noted that after 24 hours (by February 21 at 0900 UTC/4:00 a.m. EST), cooler sea surface temperatures and increasing vertical wind shear will take a toll on the tropical cyclone and start to weaken it.
JTWC forecasters expect by the second day that Guito will being transitioning into an extra-tropical storm, a process that will take another day over the open waters of the Southern Indian Ocean.

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.
The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...
Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
