First warm blooded fish
Researchers have discovered something surprising about the deep sea dweller known as the opah; It’s got warm blood. Fishes are unable to upregulate the temperature of their blood, but the opah with warm blood is able to swim faster at depths near 400m.
That makes the opah (Lampris guttatus) the first warm-blooded fish every discovered.
How to detect drug use from a finger print
Using different types of an analytical chemistry technique known as mass spectrometry to analyse fingerprints, researchers can identify persons who have ingested cocaine and distinguish from persons who have just touched cocaine.
“When someone has taken cocaine, they excrete traces of benzoylecgonine and methylecgonine as they metabolise the drug, and these chemical indicators are present in fingerprint residue,” said lead author Dr Melanie Bailey from the University of Surrey.
Furthest Galaxy Yet
Leapfrogging backward in time to when the universe was apparently feeling its oats, a group of astronomers reported Tuesday that they had measured a bona fide distance to one of the farthest and thus earliest galaxies known.
Girls In ICT Honored In Ghana
Miss Selma Agbevanu of Kabore Junior High School (JHS) Ho, emerged as this year’s best “Girls in ICT” performer in the Volta Region.
She beat a field of 99 other JHS girls shortlisted from more than 200 others who emerged winners in ICT quiz competitions held in 18 Community Information Communication centres in the region as part of this year’s “National Girls in ICT” celebration.
Weaver Ants Raise Cashew Nut Yields
Patrols of ants on cashew nut trees can roughly double the yield of the crop, according to researchers in Benin.
The researchers say that African weaver ants (Oecophylla longinoda) are an effective natural way to reduce considerable losses of cashew nuts from insect pests, such as fruit flies, and improve cashew quality, on farms in many African countries.
From Curved To Flat Lens
As we dream of smartphones that could roll up or slip into a wallet, laboratory researchers have made inroads with flexible circuits, batteries and displays. The curved lens has always stood in the way of this progress…..
The gently curved lentil served as the namesake for the similarly shaped lens. Future cameras, however, may focus light by relying on flat lenses. Physicists are making major advancements with planar lenses that can scatter and bend rays of light.
Effective Solar Roads In Netherlands
The Netherlands made headlines last year when it built the world’s first solar road – an energy-harvesting bike path paved with glass-coated solar panels.
Now, six months into the trial, engineers say the system is working even better than expected, with the 70-metre test bike path generating 3,000 kWh, or enough electricity to power a small household for a year.
Drug-resistant typhoid fever becoming an epidemic
The world is facing an epidemic of multidrug resistant typhoid fever. That’s the conclusion of the largest study to date of genomes of the bacterium that causes the diseases, Salmonella enterica Typhi. According to the researchers, a clone of the bacterium that’s frequently multidrug resistant, called H58, is rolling across Asia and Africa. Its spread is likely to increase the cost of treatments and lead to more complications, they warn.
High-performance 3-D microbattery
By combining 3D holographic lithography and 2D photolithography, researchers from the University of Illinois at Urbana-Champaign have demonstrated a high-performance 3D microbattery suitable for large-scale on-chip integration with microelectronic devices.
In this project, the researchers developed an effective method to make high-performance 3D lithium-ion microbatteries using processes that are highly compatible with the fabrication of microelectronics
Make computer brains smarter by making them more like ours
In what marks a significant step forward for artificial intelligence, researchers at UC Santa Barbara have demonstrated the functionality of a simple artificial neural circuit. For the first time, a circuit of about 100 artificial synapses was proved to perform a simple version of a typical human task: image classification.
Ghanaian student wins Best Paper Award in Italy
A Ghanaian PhD student at the University of Copenhagen in Denmark Mr. Isaac Ankamah-Yeboah has won this year’s Best Student Paper Award instituted by the European Association of Fisheries Economist (EAFE) in Salerno, Italy.
Mr. Ankamah-Yeboah, a former student of the University of Ghana and currently pursuing a doctoral programme in Environmental Resource Economics, Fisheries and Aquaculture emerged the best for his profound Research work on Organic Aquaculture.
