Ei taida olla vielä virallisesti otsikoissa, mutta tämän päivän tärkein uutinen ilman muuta on, että Jarmo Lindberg nousee seuraavaksi Puolustusvoimain komentajaksi.
Olihan tuosta uutinen Ylen sivuilla jo kaksi päivää sitten.
Aamulehti uutisoi nimityksestä tuoreeltaan alle tunti takaperin.
Komentajien vaihdokset ovat toki tärkeitä uutisia. On muuten aika harvinaista päästä ilmavoimista puolustusvoimain komentajaksi, Lindberghän on alun perin ilmavoimien miehiä. Olisiko Jarl Lundqvist ollut edellinen ilmavoimista komentajaksi noussut?
No joo, onhan se uutisoitu kyllä, mutta virallinen nimitys tapahtuu tänään Presidentin esittelyssä.
Lindberg on ensimmäinen virkaan nimitetty Ilmavoimien mies, juuri tästä syystä olenkin niin toiveikas.
Lundqvistiä ei oikeastaan lasketa, hän oli va. komentajana n. vuoden verran ilman varsinaista virkanimitystä, kun Mannerheimista tuli presidentti.
Aamulehdessä ainakin oli uutinen seuraavasti: "Tasavallan Presidentti Sauli Niinistö on nimittänyt kenraaliluutnantti Jarmo Lindbergin puolustusvoimain komentajan virkaan elokuun alusta alkaen viiden vuoden määräajaksi", eli virallinen nimitys on käsittääkseni tapahtunut.
Ensimmäinen puolustusvoimain komentaja Mannerheimin presidentiksi tulon jälkeenhän oli Heinrichs, joka kuitenkin erosi tehtävistään silloisten poliittisten tilanteiden takia. Lundqvist oli tosiaan tittelilla va. puolustusvoimain komentaja, mutta ainakin Puolustusvoimien omilla sivuilla Lunqvist on luokiteltu komentajaksi siinä missä muutkin, joten laskisin kyllä hänet ensimmäiseksi ilmavoimia edustaneeksi ylimmäksi komentajaksi.
Eli jos Lundqvist lasketaan, niin ilmavoimista on tullut kaksi komentajaa ja merivoimista kaksi, kaikki muut ovat maavoimista. Aika selkeä painotus, mutta taitaa olla samanlainen käytäntö muissakin maissa eli maavoimista päästään koko puljun komentajaksi muita haaroja todennäköisemmin.
Ei taida olla vielä virallisesti otsikoissa, mutta tämän päivän tärkein uutinen ilman muuta on, että Jarmo Lindberg nousee seuraavaksi Puolustusvoimain komentajaksi.
Toki olet oikeassa noissa faktoissasi.
Mutta sanotaanko nyt vaikka niin, että ensimmäistä kertaa Puolustusvoimilla tulee olemaan nykyaikaista ilmasodankäyntiä ymmärtävä modernin ajan komentaja. Ilmaherruuden merkitystä nykyajan sodankäynnissä on tällä palstalla kai turha enää enempää avata, siitä on olemassa täälläkin ansiokkaita analyysejä jo riittämiin.
Tämä on totta, ilmasodankäynnin päälle ymmärtävää komentajaa tarvitaan ehdottomasti. Ja eiköhän Lindberg ymmärrä, hänhän oli Hornet-koneiden hankintaprosessissa kiinteästi mukana.
Ilmaherruutta ei voi ainakaan Ruotsin puolustusvoimien varaan jättää kuten joku näillä palstoilla jo ehti ehdottaa, siellähän uskottavaa ilmapuolustusta ei käytännössä enää ole. Ellei sitten leikkimielisesti laske maahan syöksyviä Jas Gripeneitä omanlaisekseen ilma-aseeksi.

Belo Monten patoa eivät varmastikaan saa estettyä ja tuskin onnistuvat estämään myöskään kaivostoimintaa. Vastaavia pato- ja kaivoshankkeita on Amazonin alueella muitakin. Viime vuonnahan otettiin käyttöön esimerkiksi Madeiralle, Amazonin suurimmalle sivujoelle, rakennetun Santo Antonion padon (3150 MW) ensimmäiset turbiinit ja samalle joelle on rakenteilla myös Jirau (3750 MW).
Flooding in Brazilian state Rondonia has caused the country's federal court to order new environmental impact studies for the 3,568-MW Santo Antonio and 3,750-MW Jirau hydroelectric projects.

Last week the Harvard-Smithsonian Center for Astrophysics (CfA) stated rather nonchalantly that they will be hosting a press conference on Monday, March 17th, to announce a “major discovery.” Without a potential topic for journalists to muse on, this was as melodramatic as it got.
But then the Guardian posted an article on the subject and the rumors went into overdrive. The speculation is this: a U.S. team is on the verge of confirming they have detected primordial gravitational waves — ripples in the fabric of spacetime that carry echoes of the big bang nearly 14 billion years ago.
Rumors Flying Nearly as Fast as Their Subject: Have Gravitational Waves Been Detected?
We report a measurement of the B-mode polarization power spectrum in the cosmic microwave background (CMB) using the Polarbear experiment in Chile. The faint B-mode polarization signature carries information about the Universe's entire history of gravitational structure formation, and the cosmic inflation that may have occurred in the very early Universe.

Mitään juttua tätä koskien ei vielä näytä olevan missään, mutta eiköhän asia tuota koske, koska viime viikolla tämän asian tiimoilta ilmestyi jo yksi paperi, tosin kyseessä oli eri tutkimusryhmä.
Researchers from the BICEP2 collaboration today announced the first direct evidence supporting this theory, known as "cosmic inflation." Their data also represent the first images of gravitational waves, or ripples in space-time. These waves have been described as the "first tremors of the Big Bang." Finally, the data confirm a deep connection between quantum mechanics and general relativity.
"This is really exciting. We have made the first direct image of gravitational waves, or ripples in space-time across the primordial sky, and verified a theory about the creation of the whole universe," said Chao-Lin Kuo, an assistant professor of physics at Stanford and SLAC National Accelerator Laboratory, and a co-leader of the BICEP2 collaboration.

British scientists have successfully revived mosses that have been frozen under the Antarctic ice for 1,500 years. The researchers thawed out the ancient vegetation and were surprised to see new shoots rapidly appear. While bacteria of a similar age have been recovered before, the scientists say these are the oldest plants to be brought back to life.

During the experiments, EAST sustained diverted plasma for a pulse length of 411 seconds, with a central electron temperature of more than 20 million °C, and central plasma density of 2 x 10^19m^-3. This broke the world diverted plasma record by an order of magnitude. At the same time, EAST achieved stationary H-mode plasma discharges of more than 30 s, demonstrating that China has become a leading country in the world in steady-state high performance plasma research.
Prof. JIANG Zonglin and CAS Member Prof. YU Hongru from the CAS Institute of Mechanics, along with their team, have developed the largest hypersonic shock tunnel in the world. The shock tunnel is based on the detonation-driven method proposed in China and incorporates a series of innovative techniques for prolonging shock tunnel test duration, such as the tailored interface condition for a detonation-driven shock tunnel, wave-reflection damping during the nozzle starting process, shock/boundary layer interaction control near the end of the driven section, and a backward-running detonation driver with high-pressure performance. The shock tunnel is about 265 m in length with a nozzle exit diameter of 2.5 m. It can reproduce airflows of Mach 5~9 at an altitude of 25~50 km with a test time of 100 milliseconds. In terms of performance, it ranks first among the most advanced hypersonic test facilities in the world.

The coronal mass ejection, or CME, event was likely more powerful than the famous Carrington storm of 1859, when the sun blasted Earth's atmosphere hard enough twice to light up the sky from the North Pole to Central America and allowed New Englanders to read their newspapers at night by aurora light, said CU-Boulder Professor Daniel Baker. Had it hit Earth, the July 2012 event likely would have created a technological disaster by short-circuiting satellites, power grids, ground communication equipment and even threatening the health of astronauts and aircraft crews, he said.
While typical coronal mass ejections from the sun take two or three days to reach Earth, the 2012 event traveled from the sun's surface to Earth in just 18 hours. "The speed of this event was as fast or faster than anything that has been seen in the modern space age," said Baker. The event not only had the most powerful CME ever recorded, but it would have triggered one of the strongest geomagnetic storms and the highest density of particle fluctuation ever seen in a typical solar cycle, which last roughly 11 years.
2012 solar storm points up need for society to prepare
Dr. Ying Liu of the Chinese Academy of Sciences' State Key Laboratory of Space Weather and coauthors from the US (including two STEREO Principal Investigator teams), Austria, Finland, and France believe this extreme event was due to the interaction of two CMEs separated by only 10 to 15 minutes. The resulting interplanetary CME's remarkable speed may be due to its traveling through a region that had been cleared out by another CME four days earlier.
The "Perfect" Solar Storm?
Such reactors offer inherent safety characteristics and are small enough to be factory-built, offering the opportunity to build as many modules as needed.
Although various HTGR projects have been under development around the world over the years, China's HTGR project is currently the closest to commercial realisation. Construction work began on two demonstration HTGR units at Shidaowan, Shandong province, in late 2012, with Tsinghua University-CNECC joint venture Chinergy the main contractor for the nuclear island. The plant's twin HTR-PM units will drive a single 210 MWe turbine. Eighteen further units are proposed for the site.

An international team of scientists led by Graham Pearson, Canada Excellence Research Chair in Arctic Resources at the U of A, has discovered the first-ever sample of a mineral called ringwoodite. Analysis of the mineral shows it contains a significant amount of water—1.5 per cent of its weight—a finding that confirms scientific theories about vast volumes of water trapped 410 to 660 kilometres beneath the Earth, between the upper and lower mantle.
Vast Oceans Beneath the Earth
The seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated. "It is now on par with the methane being released from the arctic tundra, which is considered to be one of the major sources of methane in the Northern Hemisphere," said Natalia Shakhova, one of the paper's lead authors and a scientist at the University of Alaska Fairbanks. "Increased methane releases in this area are a possible new climate-change-driven factor that will strengthen over time."
Arctic seafloor methane releases double previous estimates
"We carried out checks at about 115 stationary points and discovered methane fields of a fantastic scale - I think on a scale not seen before. Some of the plumes were a kilometre or more wide and the emissions went directly into the atmosphere - the concentration was a hundred times higher than normal," he said.

The WMO assessment coincides with exceptionally warm air and water this month in the Arctic. The sea ice, that forms and melts each year, would normally be still growing strongly in mid-February, but has dramatically slowed in the last two weeks and now covers 14.36 million square miles – the lowest extent ever recorded in February.
"The Arctic is pretty warm everywhere. If I look at temperature anomalies, there's a huge anomaly over the Barents Sea and Sea of Okhotsk of about 10C (above normal) compared to 1981-2010," said Julienne Stroeve, a senior scientist at the US National Snow and Ice Data Centre at Boulder, Colorado.

Maailman varhaisimmat yliopistot löytyivät Intiasta. Riippuen siitä miten yliopiston määrittelee, niin ensimmäinen yliopisto löytyi joko Taksilasta tai Nalandasta.
Founded in the fifth century, Nalanda at its peak attracted some 10,000 students from across Asia to study Buddhism, law, literature, and philosophy. It is said to have been the first global institution of higher learning — and, Indians note, one created long before the development of universities in Europe.
Mr. Sen, the Harvard economist and Nobel laureate, is now part of an effort to capitalize on Nalanda’s legacy by building a new university with the same name, not far from the original site, in what is now the northeastern state of Bihar.
Indians Plan Rebirth for 5th-Century University
a Chinese-led team is planning a mammoth neutrino detector, meant to capture enough neutrinos from nearby nuclear reactors to determine which of the three known types, or flavors, of neutrinos are heavier or lighter. That mass hierarchy could be key to explaining how neutrinos get their mass, and measuring it would be a coup for China's particle physicists.
China Builds Mammoth Detector to Probe Mysteries of Neutrino Mass
Work has started on a huge underground neutrino lab in China. The $330m Jiangmen Underground NeutrinoObservatory (JUNO) is being built in Kaiping City, Guangdong Province, in the south of the country around 150 km west of Hong Kong. When complete in 2020, JUNO is expected to run for more than 20 years, studying the relationship between the three types of neutrino: electron, muon and tau.
The design concept for the detector was completed last year and it will be built by the Institute of High Energy Physics (IHEP), which is part of the Chinese Academy of Sciences (CAS). JUNO will require an 80 m high and 50 m diameter experimental hall located 700 m underground. Its detector – filled with 20,000 tonnes of liquid scintillator – will use more than 15,000 photomultiplier tubes to detect the scintillation light that is created when a neutrino hits a hydrogen atom.

Scientists have created the first synthetic chromosome for yeast in a landmark for biological engineering. Previously synthetic DNA has been designed and made for simpler organisms such as bacteria.
The paper describing the first synthetic chromosome concludes with a far-reaching vision looking beyond yeast to more sophisticated organisms, saying:
"it will soon become feasible to synthesise eukaryotic genomes, including plant and animal genomes".
In his interview, Dr Boeke explained that this will not be immediate but is getting closer.
"It's still aways off in the future to do entire chromosomes for those organisms but certainly mini chromosomes containing tens or even hundreds of genes are definitely within the foreseeable future," he said.
Scientists hail synthetic chromosome advance
Researchers from the United States and China said Thursday they have developed a simple method for filtering light waves based on direction, a finding that could ultimately lead to advances in solar photovoltaics, detectors for telescopes and microscopes, and privacy filters for display screens.
The findings could also prove useful in optical systems, such as microscopes and telescopes, for viewing faint objects that are close to brighter objects, for example, a faint planet next to a bright star.
