Museum peace

first_imgFOR a while, it looked like the Children’s Museum of Los Angeles was going to become a monument to apathy, and not the beacon of learning it was meant to be. But prospects for the San Fernando Valley’s first museum have improved, and there’s reason to hope that the facility might just see the light of day after all. A month ago, the museum was $3.3 million short on its bills, and contractors were threatening to pack up their tools and go home. But the city bailed the museum out with a short-term emergency loan of $1.75 million. Meanwhile, contributors have stepped up, big time. 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set! Over the last four weeks, the museum has raised $1 million, including a single anonymous donation of $500,000, which is more than it raised in the entire previous year. It might have taken a crisis to spur them to action, but local residents and businesses finally seem energized about the need for this priceless institution. That said, museum officials still must raise another $250,000 in the next 10 days – and beyond that, it will take $20 million more to complete the project. So we still need to dig deep.

Which drive is best for school?

first_imgQ: How much memory do you recommend for a new PC today with Windows Vista Ultimate Edition? A: It depends what you plan to do with your computer. For browsing the Web and checking e-mail I would get 1 GB (with 512 MB as an absolute minimum). If you plan to edit video or photographs, make slide shows or other intensive tasks, get 4 GB with 2 GB at a minimum. The more RAM the better, and at today’s pricing, there is little to lose by buying it upfront. Weekly Web wonder I recently found my dream car on Cars.com and I am fascinated by how the technology is changing the auto marketplace. Even if you’re not in the market now, check out how the site is changing how we buy cars. James Derk is owner of CyberDads, a computer repair firm, and tech columnist for Scripps Howard News Service.

Reader mail fills the box today ? school is back in session for many kids and the letters are pouring in. Question: I need to buy a USB thumb drive for my son to take to middle school to save papers on. What size do you recommend? Answer: I would get a 512 MB or a couple of 256s ? they are cheap and plentiful. (A trade show I attended recently had booths giving away 64MB sticks by the handful.) Get one with a sturdy keychain hook on it and put it on his house keys or on a ring in his backpack. Also put his name on it with a permanent marker so the teacher will know which kid left it in the drive (and he will.) Don’t get a large USB drive because he will just lose it. Brand doesn’t matter. Q: What screen resolution do you recommend for a laptop? I see varying qualities of screens out there when you try to order. A: I would get one where the second number is in four digits. In other words, a laptop with maximum resolution of 1280 x 768 will mean icons that for many people are too large and can’t be further reduced to get more stuff on the screen. If you find one where the second number is in four digits you likely will be happier unless you have weak eyes and like the larger icons and screen size. Q: What is the best free e-mail account out there? I need one with ample storage and good spam filtering. I don’t mind spending a little money annually if I have to. A: My favorite for these tasks is Google’s Gmail. It offers more storage than any reasonable person will need for e-mail and has good spam filtering capability (some will sneak through but it is pretty effective.) In second place would be Yahoo, but I think it’s a second-tier offering from a second-tier company. Make sure you don’t keep anything irreplaceable in a free e-mail account without making a backup. You never know when a free offering goes “poof.” Q: Can I watch television on my computer? A: In a couple of ways. You can visit a TV network home page and often watch streaming video there, either live or on tape. Or you can install a TV card in your PC and watch TV live via that. Some computers have these built in (especially if you have Windows Media Center Edition installed) so check your PC before you order the hardware card. last_img read more

 

Kings dim the Stars, break slump

first_img AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREGame Center: Chargers at Kansas City Chiefs, Sunday, 10 a.m.Over the previous four games, the Kings had put together a little momentum after a dismal start to the season. But Dallas has been the black hole where all positives go to die for the Kings. Not this time. Alexander Frolov beat Dallas goalie Marty Turco off a pass from Derek Armstrong early in the third period for the winning goal as the Kings ended a nine-game losing streak to the Stars with a 2-1 victory Thursday at Staples Center in front of a crowd of 14,559. By beating the team that has tormented them over the last two seasons – as well as an early Stanley Cup favorite – the Kings (5-6-0) officially have something going. NHL: Frolov goal helps L.A. halt a nine-game skid versus Dallas. By Matthew Kredell STAFF WRITER There’s no better heat-check for the Kings than the Dallas Stars. “It’s a big step for our team,” Frolov said. “There’s been a lot of changes since last year, a lot of new people, and now we’re proving that we are a good team and can beat anyone in this league. We showed it tonight.” The Kings have won three straight – something they never did last year – and four of five since beginning the season 1-5, and seem to have found their goalie in Jason LaBarbera. LaBarbera made his third consecutive start, the first time this season a goalie has started three in a row for the Kings. His performance might have been better than his shutout Tuesday. He stopped 29 of 30 shots after only being challenged 17 times against Nashville. He kept out 13 shots in the third period alone to beat Dallas (4-3-2). “We’re coming together as a team and that’s the big thing,” LaBarbera said. “You can see it on everyone’s faces. We didn’t have that confidence and swagger earlier in the year, and now all of a sudden we have it.” Frolov, who failed to score in the team’s first eight games amid mounting criticism, now has goals in three consecutive games and points in seven in a row. His poor start could be blamed on a groin injury that kept him out most of training camp. “He looks like he’s getting his legs,” Kings coach Marc Crawford said. “He’s looks like the Fro we saw last year, where he gets those chances and he outskates people.” The Kings grabbed the momentum in the second period, outshooting the Stars, 19-6, after being outshot, 11-6, in the opening period. Crawford mixed and matched the lines more than ever before, starting Anze Kopitar with Frolov and Ladislav Nagy, and later putting leading scorer Michael Cammalleri with Brian Willsie and Derek Armstrong to set up the team’s first goal. Willsie dived around Turco and poked in a rebound of a shot from Cammalleri to tie the game midway through the second period. It was the first goal of the season for Willsie, who has been a healthy scratch in more than half the team’s games. The Kings killed back-to-back penalties in the final six minutes to hold on to the victory. Notes: The Kings, in conjunction with the Salvation Army, will begin collecting donations at their next four home games to aid those left homeless by the Southern California wildfires. During the Nov. 10 games against Dallas, each player will wear a commemorative Southern California Fire Department patch on his jersey, and the jerseys will be auctioned with all proceeds going to the fire victims. … LaBarbera has stopped 89 of the last 92 shots he has faced. matthew.kredell@dailynews.com160Want local news?Sign up for the Localist and stay informed Something went wrong.

SA students in global aerospace contest

first_img7 February 2013 A team of South African students from the University of the Witwatersrand (Wits) have been selected as only one of three teams from Africa to move on to the next round of the global aerospace Fly Your Ideas competition. Fly Your Ideas is a biennial competition run by aircraft manufacturer Airbus and backed by the United Nations Educational, Scientific and Cultural Organisation (Unesco). The competition is run to encourage the proposal of new and innovative ideas to help the aerospace and air transport industry become sustainable and eco-efficient. “I am delighted to see the enthusiasm of the teams and our Airbus experts who are committed to sharing their know-how with these students from around the world who are the innovators of the future.” The Wits team, called the Stormhawks – made up of Pitso Mangoro, Muhammed Dangor, Sambharthan Cooppan, Tshireletso Mango and Azhar Cassim – entered their idea of an aircraft control system to replace fly-by-wire technology with a hybrid visible light communication system. The Stormhawks were selected as one of 100 student teams from across five continents to proceed to the second round of the competition. Of the remaining teams, only 3% are from Africa, 3% are from the Middle East, 8% from the Americas, 37% from Europe and 49% from Asia Pacific. “At this stage of the competition, Airbus has identified the most innovative ideas from over 600 teams who entered the third edition of the Unesco-backed competition,” the aircraft manufacturer said. Each of the teams have until 12 April to explore, test and develop their concepts with the help of an Airbus mentor and expert. There will be another elimination round before the final five teams present their concepts to a panel of industry experts at Airbus headquarters in Hamburg, Germany on 12 June. The winners will be announced at Unesco headquarters in Paris, France on 13 June. The winning team will walk away with €30,000 (over R300 000) and the chance to host an “innovation week” on their university campus run by Airbus experts. SAinfo reporterlast_img read more

 

Do gut bacteria make a second home in our brains?

first_imgImages of human brain slices reveal bacteria, shown here to the left of a blood vessel—tantalizing but preliminary evidence of a “brain microbiome.” Rosalinda Roberts, Courtney Walker, and Charlene Farmer SAN DIEGO, CALIFORNIA—We know the menagerie of microbes in the gut has powerful effects on our health. Could some of these same bacteria be making a home in our brains? A poster presented here this week at the annual meeting of the Society for Neuroscience drew attention with high-resolution microscope images of bacteria apparently penetrating and inhabiting the cells of healthy human brains. The work is preliminary, and its authors are careful to note that their tissue samples, collected from cadavers, could have been contaminated. But to many passersby in the exhibit hall, the possibility that bacteria could directly influence processes in the brain—including, perhaps, the course of neurological disease—was exhilarating.“This is the hit of the week,” said neuroscientist Ronald McGregor of the University of California, Los Angeles, who was not involved in the work. “It’s like a whole new molecular factory [in the brain] with its own needs. … This is mind-blowing.”The brain is a protected environment, partially walled off from the contents of the bloodstream by a network of cells that surround its blood vessels. Bacteria and viruses that manage to penetrate this blood-brain barrier can cause life-threatening inflammation. Some research has suggested distant microbes—those living in our gut—might affect mood and behavior and even the risk of neurological disease, but by indirect means. For example, a disruption in the balance of gut microbiomes could increase the production of a rogue protein that may cause Parkinson’s disease if it travels up the nerve connecting the gut to the brain.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Talking hoarsely above the din of the exhibit hall on Tuesday evening, neuroanatomist Rosalinda Roberts of The University of Alabama in Birmingham (UAB), told attendees about a tentative finding that, if true, suggests an unexpectedly intimate relationship between microbes and the brain.Her lab looks for differences between healthy people and those with schizophrenia by examining slices of brain tissue preserved in the hours after death. About 5 years ago, neuroscientist Courtney Walker, then an undergraduate in Roberts’s lab, became fascinated by unidentified rod-shaped objects that showed up in finely detailed images of these slices, captured with an electron microscope. Roberts had seen the shapes before. “But I just dismissed them, because I was looking for something else,” she says. “I would say ‘Oh, here are those things again.’”But Walker was persistent, and Roberts started to consult colleagues at UAB. This year, a bacteriologist gave her unexpected news: They were bacteria. Her team has now found bacteria somewhere in every brain they’ve checked—34 in all—about half of them healthy, and half from people with schizophrenia.Roberts wondered whether bacteria from the gut could have leaked from blood vessels into the brain in the hours between a person’s death and the brain’s removal. So she looked at healthy mouse brains, which were preserved immediately after the mice were killed. More bacteria. Then she looked at the brains of germ-free mice, which are carefully raised to be devoid of microbial life. They were uniformly clean.RNA sequencing revealed that most of the bacteria were from three phyla common to the gut: Firmicutes, Proteobacteria, and Bacteroidetes. Roberts doesn’t know how these bacteria could have gotten into the brain. They may have crossed from blood vessels, traveling up nerves from the gut, or even come in through the nose. And she can’t say much about whether they’re helpful or harmful. She saw no signs of inflammation to suggest they were causing harm, but hasn’t yet quantified them or systematically compared the schizophrenic and healthy brains. If it turns out that there are major differences, future research could examine how this proposed “brain microbiome” could maintain or threaten the health of the brain.In the initial survey of the electron micrographs, Roberts’s team observed that resident bacteria had puzzling preferences. They seemed to inhabit star-shaped cells called astrocytes, which interact with and support neurons. In particular, the microbes clustered in and around the ends of astrocytes that encircle blood vessels at the blood-brain barrier. They also appeared to be more abundant around the long projections of neurons that are sheathed in the fatty substance called myelin. Roberts can’t explain those preferences but wonders whether the bacteria are attracted to fat and sugar in these brain cells.Why haven’t more researchers seen bacteria in the brain? One reason could be that few researchers subject postmortem brains to electron microscopy, Roberts says. “Pairing up a neuroanatomist with a brain collection just doesn’t happen very often.” And neuroscientists may—as she did until recently—disregard or fail to recognize bacteria in their samples.Roberts acknowledges that her team still needs to rule out contamination. For example, could microbes from the air or from surgical instruments make it into the tissue during brain extraction? She plans to hunt for such evidence. She also wants to rule out that the solutions that preserve mouse brains introduce or nourish bacteria. Among visitors to the poster, “There were a few skeptics,” Roberts notes. “I have that part of me, too.” But even if the bacteria were never really thriving in living brains, the patterns of their postmortem invasion are intriguing, she says.If we really have the brain microbiome Roberts proposes, “There is much to investigate,” says Teodor Postolache, a psychiatrist at the University of Maryland in Baltimore. He has studied the protozoan parasite Toxoplasma gondii, which invades the brain but doesn’t always cause obvious disease. “I’m not very surprised that other things can live in the brain, but of course, it’s revolutionary if it’s so,” he says. If these common gut bacteria are a routine, benign presence in and around brain cells, he says, they might play a key role in regulating the brain’s immune activity. “It’s a long road to actually prove that,” he says, but “it’s an exciting path.” By Kelly ServickNov. 9, 2018 , 2:45 PM Do gut bacteria make a second home in our brains?last_img read more
