16. april 2010, 15:48:08Gå til den fulde artikel
Forskare vid Institutet för rymdfysik (IRF) har observerat en minimagnetosfär över en magnetisk anomali på månen genom att använda mätningar av energetiska neutrala atomer från det svenska satellitinstrumentet SARA (Sub-keV Atom Reflecting Analyzer) ombord på den indiska rymdfarkosten Chandrayaan-1. Tillsammans med kollegor från Indien, Schweiz och Japan, har IRF-forskarna publicerat sina resultat i veckans nummer av tidskriften Geophysical Research Letters. En bild på den magnetiska anomalin på månen i reflekterade atomer finns på tidskriftens omslag (vol. 37, nr 5).

Brintgasproduktion kan fordobles med ny superbakterie====Ny superbakterie dubblar vätgasproduktionen====
14. april 2010, 10:43:59Gå til den fulde artikel
Vätgas används idag främst för att framställa kemikalier, men spås en blomstrande framtid som drivmedel i bilar i kombination med bränsleceller. För att tillverka vätgas på ett klimatneutralt sätt tillsätter man bakterier till skogs- eller hushållsavfall, ungefär som man producerar biogas. Ett problem med det här tillverkningssättet idag är att det ger lågt vätgasutbyte, alltså att råmaterialet genererar lite vätgas. Nu har forskare för första gången studerat en nyupptäckt bakterie som ger dubbelt så mycket vätgas jämfört med dagens bakterier. Resultaten, som visar hur, när och varför bakterien kan utföra sitt utmärkta arbete, ökar konkurrensmöjligheterna för biologisk framställning av vätgas.
Mænd i forretningslivet danner uformelle netværk i jagtklubber (Sverige)====Slutna nätverk och tradition stänger ute kvinnorna från styrelserummen====
14. april 2010, 10:43:54Gå til den fulde artikel
Manlighet konstrueras och reproduceras genom slutna nätverk. Samtidigt är kvinnor fortfarande underrepresenterade i styrelser och börsnoterade företag. Ekonomhistorikern Therese Nordlund Edvinsson vid Stockholms universitet menar att kravet på kvotering i börsstyrelser måste ses i ljuset av den manliga hegemonins historiska rötter inom näringslivets elit. I boken Broderskap i näringslivet: en studie om homosocialitet i Kung Orres Jaktklubb 1890-1960 exemplifierar hon hur män i näringslivet byggde informella nätverk och hur kvinnor kunde vinna insteg i mansdominerade miljöer.
Industrien bør bruge storytelling====Kommunikation på kollisionskurs====

Kommunikationen mellan börsföretagen och finansmarknaden fungerar dåligt när det gäller t ex kompetens, kundrelationer eller miljöfrågor, som alla är exempel på icke-materiella resurser. Det visar en färsk studie från Mälardalens högskola. Anledningen är att båda sidor har svårt att förstå varandra på grund av att de blir systemblinda. Men storytelling kan vara lösningen.

Using a combination of crystallization and physics-based simulations, researchers defined the structure of a protein, cadherin-23, that helps mediate our perception of sound. Their findings show the protein to be a rigid structure whose strength results from calcium ions binding within it. However, mutations that interfere with calcium-ion binding undermine the protein's firm structure and make it less resilient. This provides a possible explanation for certain forms of inherited deafness.

A new switch that enables Salmonella bacteria to sabotage host cells is revealed in a study published today in the journal Science. The researchers behind the study, from Imperial College London, say that the new finding could ultimately lead to drugs that interfere with the switch in order to combat Salmonella and possibly other bacterial infections.In humans, Salmonella causes diseases ranging from gastroenteritis to typhoid fever.
Nervecellestudie: Dyrkede hjerne-nervecellers basale hukommelsesmekanismer studeres. Nerverne udbredte sig i små gruber, og vinkelret herpå kunne der via kanaler tilsættes stoffer, som påvirkede små populationer af nervecellens synapser ====Neurons growing in line====

Frankfurt brain researchers have developed a novel method to grow cultured neurons in order to investigate basic mechanisms of memory. They grew two separate populations of neurons in microfluidic platforms. These neurons extended their processes through tiny grooves, to meet each other and form synaptic connections. Perpendicular to the grooves, a perfusion channel was constructed that allows the researchers to manipulate very small populations of synapses with drugs or neurotransmitters.

A typical human cell contains hundreds of mitochondria — energy-producing organelles — that continually fuse and divide. Relatively little is known, however, about why mitochondria undergo this behavior. Now, a team of researchers — led by scientists at Caltech — have taken steps toward a fuller understanding of this process by revealing just what happens to the organelle, its DNA (mtDNA), and its energy-producing ability when mitochondrial fusion fails.
