Hydrogen Technology as Our Next Fuel?

2 comments Yessi Pratiwi — July 18, 2009 / 10:38 pm

Have you ever imagined about using Hydrogen as fuel for your daily life? Some of you may have still no idea about the use of this element. Recently, Engineers at the University of Leeds believes that someday, we’ll be able to operate laptop or cars by the old chip fat, extracted from the waste materials. They [...]

Giant Sperm Found in Microfossil

It was reported in ScienceDaily that an international group of researchers led by Dr. Renate Matzke-Karasz, Ludwig-Maximilians-Universität (LMU) in Munich, has indirectly detected signs of giant sperm in fossilized ostracods. Picture shows the length of the filamentous, helical sperm-cells of freshwater ostracods can reach up to ten times the body length of its producer. The longest [...]

New Chemical Weapon In Poison Frogs’ Arsenal Found

Comments Yessi Pratiwi — June 10, 2009 / 6:26 pm

In the news reported by ScienceDaily, June 9th, it was mentioned that there has been found a surprising chemical weapon used by some Amazonian poison frogs. The poisen itself identified as never been known before, called as the N-methyldecahydroquinolines. As I read on some sources, it is reported that N-methyldecahydroquinolines known to beat the Class of Alkaloids. [...]

Smart Polymer Reduces Radioactive Waste

1 comment Yessi Pratiwi — May 15, 2009 / 5:39 pm

Radioactive wastes are waste products containing radioactive materials. They are usually the products of nuclear processes, such as nuclear fission. However, industries not directly connected to the nuclear industry may produce large quantities of radioactive waste. Recently, it has been reported in ScienceDaily that Scientists in Germany and India are reporting development of a new polymer [...]

New Energy Source?

1 comment Yessi Pratiwi — May 6, 2009 / 10:53 am

As well as green plants and algae, some bacteria are also capable of using the energy in sunlight, to get their energy through photosynthesis. The green bacteria are particularly specialised for growth at very low light intensities. The ability of green bacteria to grow at very low light intensities depends on the way the light-absorbing [...]

Fossil Fuel From Burnt Ice

1 comment Yessi Pratiwi — March 27, 2009 / 12:07 pm

Biofuel known to be the solid, liquid or gaseous fuel derived from relatively recently dead biological material and is distinguished from fossil fuels, which are derived from long dead biological material. This gives us an information that biofuel can be derived from fossil fuels, and fossil fuels derived from long dead living material. What about deriving the [...]

Dogs Can Be Jealous When Treated Unfair

Beside primates, dogs recently have been found to have a jealous feeling. What a funny fact, right? NewScientist reported, when a dog treated unfair compared to another dogs in the same environment, he’ll show his envy clearly. Well, how will he act, then? Friederike Range and her colleagues at the University of Vienna, Austria, asked [...]

Faulty Copying Can Repair Genetic Damage in Ants and Minibacteria, Research Found

Comments Yessi Pratiwi — October 9, 2008 / 7:04 pm

A recent discovery on genetic repair has been published in the journal Proceedings of the National Academy of Sciences. The Uppsala researchers presenting their new finding that used minibacteria and ants. Insects like ants, tse-tse flies, and aphids known to be dependent from special minibacteria for their survival. The bacteria live in special organs inside insect’s [...]

New Invention That Kills Foodborne Pathogens in Minutes

A new technology to reduce contamination of dangerous bacteria on food has been developed by the researchers at University of Georgia Research Foundation, Inc,. For years, foodborne pathogens known to be responsible for 76 million illnesses every year (ScienceDaily). The technology has been patented by U.S. Food and Drug Administration, as antimicrobial that kills [...]

Finding The Wreckage of NASA’s Mars Polar Lander Will Lead The Clues What Went Wrong

It was revealed in NewScientist that finding the wreckage might explain why the mission of NASA’s Mars Polar Lander failed in 1999. Alfred McEwen of the University of Arizona in Tucson, US, said that if they can find the Mars Polar Lander and be convinced they understand what they’re looking at, it might provide some clues [...]
