Simulated trends in ionosphere-thermosphere climate due to predicted main magnetic field changes from 2015 to 2065

first_imgThe strength and structure of the Earth’s magnetic field is gradually changing. During the next 50 years the dipole moment is predicted to decrease by ∼3.5%, with the South Atlantic Anomaly expanding, deepening, and continuing to move westward, while the magnetic dip poles move northwestward. We used simulations with the Thermosphere-Ionosphere-Electrodynamics General Circulation Model to study how predicted changes in the magnetic field will affect the climate of the thermosphere-ionosphere system from 2015 to 2065. The global mean neutral density in the thermosphere is expected to increase slightly, by up to 1% on average or up to 2% during geomagnetically disturbedconditions (Kp ≥ 4). This is due to an increase in Joule heating power, mainly in the Southern Hemisphere. Global mean changes in total electron content (TEC) range from −3% to +4%, depending on season and UT. However, regional changes can be much larger, up to about ±35% in the region of ∼45◦S to 45◦N and 110◦W to 0◦Wduring daytime. Changes in the vertical ⃗E × ⃗B drift are the most important driver of changes in TEC, although other plasma transport processes also play a role. A reduction in the low-latitude upward⃗E × ⃗B drift weakens the equatorial ionization anomaly in the longitude sector of ∼105–60◦W, manifesting itself as a local increase in electron density over Jicamarca (12.0◦S, 76.9◦W). The predicted increase in neutral density associated with main magnetic field changes is very small compared to observed trends and other trend drivers, but the predicted changes in TEC could make a significant contribution to observationally detectable trends.last_img read more

House price growth rebounds in July as activity bounces back after lockdown

first_imgHome » News » COVID-19 news » House price growth rebounds in July as activity bounces back after lockdown previous nextHousing MarketHouse price growth rebounds in July as activity bounces back after lockdownAnnual house price growth recovers to 1.5% in July, according to latest Nationwide house price index, with prices up 1.7% on June.Richard Reed31st July 202001,570 Views Annual house price growth recovered to 1.5% in July, according to the latest figures from Nationwide.Prices were up 1.7% month-on-month, after taking account of seasonal factors, reversing June’s fall of 1.6%.On a seasonally adjusted basis, house prices in July were 1.6% lower than in April.The nation’s largest building society says it believes the stamp duty holiday is likely to provide further support in the near term.Commenting on the figures, Robert Gardner, Nationwide’s Chief Economist, said: “The bounceback in prices reflects the unexpectedly rapid recovery in housing market activity since the easing of lockdown restrictions.Pent-up demand“The rebound in activity reflects a number of factors. Pent-up demand is coming through, where decisions taken to move before lockdown are progressing.“Behavioural shifts may be boosting activity, as people reassess their housing needs and preferences as a result of life in lockdown. Our own research, conducted in May (link), indicated that around 15% of people surveyed were considering moving as a result of life in lockdown.“Moreover, social distancing does not appear to be having as much of a chilling effect as we might have feared, at least at this stage.”Mr Gardener said the trends looked set to continue in the near term, further boosted by the stamp duty holiday.But he added: “There is a risk this proves to be something of a false dawn. Most forecasters expect labour market conditions to weaken significantly in the quarters ahead as a result of the aftereffects of the pandemic and as government support schemes wind down. If this comes to pass, it would likely dampen housing activity once again in the quarters ahead.”Short-term bounceIndustry guru Anthony Codling of property portal twindig was cautious about the results.“The day after Lloyds Bank, the UK’s largest lender cut its house price forecasts and raises them for unemployment, Nationwide reports that house prices rose in July by 1.7%,” he said.“It’s too early to tell if the stamp duty holiday may be pushing up prices, but it may well be a factor and should the UK experience a second wave of COVID this ‘bounce’ may be short-lived.”Sam Hunter, chief operating officer of Homesearch, said the Nationwide figures mirrored what the firm has been hearing from its network of agents across the country over the past few weeks – that the bounceback is in full swing, with many buyers and sellers motivated to move as a consequence of lockdown and spurred on by the stamp duty holiday.However, he added: “My concern though, is that with mortgage affordability becoming ever-more stretched, and the potential of a downturn in the autumn, this summer rebound could be short-lived in terms of price growth.“As a result, we’re recommending our agents to provide pragmatic counsel to their vendors around taking the opportunity of a busy market to price realistically and achieve a fast sale, rather than aiming to break the ceiling price of the road and have properties sitting on the books for months.“We anticipate more stock coming to the market over August and September, as discretionary sellers are tempted to try their luck given the current levels of demand.”‘Nothing short of miraculous’Managing director of Barrows and Forrester, James Forrester, said the rate at which the property market had rebounded over the past few months had been “nothing short of miraculous”.“While the current pandemic continues to dampen many aspects of life, homeownership isn’t one of them, and we should continue to see some very positive price trends play out over the year,” he said.“Those that were so quick to talk the market down seem to have now entered into an unseasonal hibernation. While they will no doubt emerge from their boltholes of negativity to forecast yet further armageddon in the even of a second-wave, it’s quite clear that the market isn’t prepared to lay down and die as they might have hoped.”Director of Benham and Reeves, Marc von Grundherr, commented: “The property market party is in full swing at the moment, and we’re yet to see the benefit of the recently announced stamp duty holiday filter through. Once that does, expect further increases in house price growth due to a notable and sustained increase in buyer demand.“London, in particular, has now turned a corner and will see the vast majority of buyers benefit from a stamp duty reprieve. This will help accelerate the capital return to form and see the region regain its seat at the helm of the UK property market, helping to drive house price growth in the right direction.“As a result, we should finish the year in a much, much better position than anyone could have imagined just a few short months ago.”Effect of stamp duty changesNationwide also looked at the effects of the stamp duty holiday in terms of the savings buyers will make.The report says the temporary increase in the tax threshold in England and Northern Ireland to £500,000 should mean that around 90% of owner-occupier transactions in England will pay no stamp duty over the next nine months.The Scottish government raised the threshold for its equivalent Land & Buildings Transaction Tax (LBTT) to £250,000, which means that 80% of home purchasers in Scotland will pay no LBTT.First-time buyers were already exempt from SDLT on purchases up to £300,000, so the changes have a greater benefit to home movers.There is also a significant skew in the beneficiaries towards wealthier households which are disproportionately in London and the South of England, where average house prices are significantly higher (see chart below). Nationwide house price index Covid house price recovery House prices rebound Stamp Duty holiday house price growth July 31, 2020Richard ReedWhat’s your opinion?

There’s A “New” Aerosmith Live Album From A 1978 Concert On Spotify And It’s Head-y As Hell

first_imgThere’s a new Aerosmith live album on Spotify, and it’s head-y as hell.The mysterious “new” album simply titled, Live Radio Broadcast, was recorded during a concert in front of Aerosmith’s hometown fans at The Music Hall in Boston back on March 28th, 1978, during the height of their commercial popularity and reckless drug use. Fans won’t find the album under the band’s official Spotify page, leading one to assume whether or not the band even knows of its existence, and who exactly had the ownership rights to add it to the popular streaming service in the first place. Regardless of how it appeared or who is responsible, the album represents a treasure trove of late-70s live recordings.The audio quality of the show is far superior to the band’s official album releases, notably their 1979 Live! Bootleg and Classics Live albums from the 1980s. The audio is loud, heavy, and authentic–exactly what you’d want out of an Aerosmith concert back in the 1970s. 1978 was an era when drugs were certainly playing a large role in the band members’ personal and professional lives, but not quite to the point yet where cocaine and heroin began working against them creatively. To put the performance into a wider rock history perspective, it is the Aerosmith equivalent to the Grateful Dead‘s famous 5/8/77 Cornell show or Rolling Stones‘ Ladies & Gentleman in terms of audio quality and on-stage chemistry from the band. Oh yeah, it’s that good. The album starts out with “Walk This Way”, one of the big singles from 1975’s Toys in the Attic featuring Joe Perry riffing away in sync with Brad Whitford with the help of a talkbox, which he would often use on that song back then. The opening performance is not too erratic or rushed as it sounds on Live! Bootleg. “Rats in the Cellar” is next, and its a dark and heavy version of the 1976 tune off of their Rocks LP, although the one downside of the recording is their traditional ending jam on that song ends abruptly. It does, however, swing right into the lively intro of “Big Ten Inch Record”, a Bull Moose Jackson blues tune which the band has used in their live set over the years. The recording really showcases Stephen Tyler blowing away on his harmonica during the intro and again in the solos, a talent of his which is greatly under-appreciated as a performer. Related: Aerosmith’s Joe Perry Reportedly Hospitalized After Performing With Billy Joel At MSGThe album continues into a fantastic and rare live version of “I Wanna Know Why”, a proto-punk song off their from their then-new studio album, 1977’s Draw The Line. The track is both fun and swanky and really shines in the way the song was meant to be heard. It also comes with a nasty guitar solo courtesy of Whitford. They followed that up with a super funky rendition of “Sight for the Sore Eyes”, before heading into “Seasons of Wither” from 1974’s Get Your Wings. The lively version of their nature-inspired song helps it rise up to its potential as some expression of power-folk psychedelia. Their super hit “Sweet Emotion” came next, although there’s nothing too special about this performance that can’t be heard on their other live albums. “Lord of the Thighs” was played next, and could easily be considered the highlight of the show. That performance just reeks of pure 1970s Aerosmith ethos–Sex, Drugs, & Rock n’ Roll. Tyler’s voice drags along with those drawn out notes in the verse. All of a sudden Perry hits the gas and takes the listener into orbit with a great solo as he and Whitford go back and forth into a nearly seven-minute jam. “Chip Away At The Stone” features some cool and noticeably clear vocal duets between Perry and Tyler during the choruses. “Get The Lead Out” is next and sounds fine, but the next track, “Get It Up”, is another one of the album’s gems. It’s rare in the Aerosmith world to hear a live recording of “Get It Up” with such good audio quality. It’s a fun live version with Perry grooving away with his guitar slide, one skill he is very good at which he displays during a brief solo at the end.“Same Old Song and Dance” and “Milk Cow Blues” keep the show going, with the other Tom Hamilton giving his usual bass solo to close out the former.The album comes to a close with three powerhouse setlist regulars–their adrenaline-pumping cover of the blues standard, “Train Kept a’ Rollin”, “Draw The Line”, and “Toys in the Attic”. The performance of “Train” is fundamentally solid for fans who are into that song and comes with a really spacey ending solo from Perry. “Draw The Line” always gets the energy going, and this performance was no exception. Perry showcases those fantastic slide skills of his while Tyler’s voice is at its peak coming out of the solo and into the final run of the chorus line. The band’s quick performance to close the show with “Toys” is by far the best live version of the early punk tune found anywhere. Distortion pedals are active and roaring from both guitarist with a mix of crunch that is borderline maddening–completely over the top and excessive, making it the perfect set closer for Aerosmith circa 1978. The album is peak Aerosmith from a decade where many rock fans and critics consider the band at their best in the first era of their nearly 50-year career.last_img read more

Senate discusses student stress

first_imgStudent Senate met Wednesday night to discuss mental health resources and general stress levels of students at Notre Dame. The goal of the conversation was to begin an ongoing dialogue about student experiences with stress and how the university’s resources can better assist the issues.Student body vice president Matt Devine began the meeting by asking the group in attendance if students are aware of their stress levels and how the levels impact their lives.The group discussed the stigma that exists when students admit to and seek mental health resources; however, the representatives also noted that the dorms serve as support system for students, giving them friends nearby to talk to about stress.Kristen Gates, a representative from Walsh Hall, said she thinks the stress levels of students stems from the desire to succeed.“There is such a high expectation for Notre Dame Students to be extremely involved and excel in academics while holding it all together, but this idea of perfection has negative effects on student stress levels.”Senate plans on holding three focus groups in the future to further gauge student perception on mental-health resources.Senate also voted to pursue a discussion with the registrar about the University’s auditing policy, which entails being able to sit in on a class and receive credit without paying for the class.Student body president Lauren Vidal also presented the State of the Union to the senate. Vidal discussed the senate’s most recent accomplishments, including the O’SNAP program, as well as other goals for the year. Vidal encouraged students to be catalysts of positive change in the campus and the world.“We must look to a time when we have all already graduated and how our actions now will effect students for generations to come,” she said.Tags: Senate, Student governmentlast_img read more

Death of Fat Cells

first_imgA team of University of Georgia researchersis the first to find that the hormone leptin causes the programmed deathof fat cells rather than simply reducing their size.The discovery helps explain why rats injected with leptin stay thinlong after treatment has stopped. It could play a significant role in usingleptin to treat obesity, said CliftonBaile, a UGA professor of foods and nutrition and animal science.Research on leptin has exploded in the two years since it was firstdiscovered by Rockefeller University researchers. The hormone is producedby the body’s fat cells and travels through the blood stream to the brain.Animals treated with leptin eat less, lose weight and expend energy ata higher rate.Pharmaceutical companies have invested hundreds of millions of dollarsresearching the use of leptin to treat obesity. Leptin-based medicationis expected to be available within five years.The UGA team’s findings about leptin’s effect on fat cells began afterHao Qian (pronounced Hall Chin), joined the UGA faculty a year ago. Qianspent several months researching apoptosis (programmed death) of spinal-cordcells following injuries.In general, apoptosis is a routine process that occurs in most tissues.It’s what causes leaves to fall from trees in autumn. It’s also how thebody eliminates diseased or unnecessary cells, such as a mother’s milk-secretingmammary cells after a baby is weaned.Apoptosis was first revealed in 1972. However, extensive research onthe role it plays in a variety of organisms didn’t begin until 1992. Thatexplains why Qian’s hypothesis about leptin’s role in the destruction offat cells was so novel.”When Hao first suggested that the fat cells’ reaction to leptin lookedlike apoptosis, we didn’t think he was right,” Baile said. However, theteam developed a series of experiments to test the hypothesis.The UGA scientists injected one group of rats with leptin, placed asecond group on a low-calorie diet and gave a third, untreated, group normalamounts of food.In comparing the DNA of the rats’ fat cells, the cells of the leptin-treatedrats clearly showed apoptosis. But the rats in the low-calorie diet andcontrol groups showed no signs of it.”The only cells affected in the leptin-treated rats were the fat cells,”Baile said. “Cells in the liver, kidney and heart, as well as both smoothand skeletal muscle were not affected. This was true in male and femalerats, young rats and older rats.”A problem with most treatments for obesity is that once the treatmentis stopped, the individual begins gaining weight almost immediately,” Bailesaid. “However, with leptin, that’s not the case.”Baile said it takes weeks for the leptin-treated rats to recover thefat they lose. “We’ve had trouble finding any fat cells in rats withinfive days of treatment,” he said.The scientists presented their results Oct. 27-28 in San Diego at theAnnual Conference on Apoptosis. They also presented some of the researchat a September workshop sponsored by the National Institutes of Healththat focused on the brain and fat cells. The research will appear in thescientific journal, Endocrinology, later this year.last_img read more

Coal Port-Expansion Sponsor in Washington State Puts Project on Hold

first_img FacebookTwitterLinkedInEmailPrint分享From the Associated Press:The sponsor of a proposed Washington state coal port for shipments of the fuel to Asia is suspending work on an environmental review because of a Native American tribe’s concerns that the project could hurt its fishing rights.SSA Marine, which retains a 51 percent ownership of the project, said Friday it was halting the environmental review while it waits for the U.S. Army Corps of Engineers to make a decision on the treaty rights of the Lummi Tribe.The Puget Sound port just south of the U.S.-Canada border would accommodate almost 60 million tons a year of coal and other commodities.Coal companies hope exports to Asia will shore up their industry, which has been battered by competition from cheap natural gas and more stringent restrictions on pollution caused by burning the fuel. Construction costs for the Gateway Pacific Terminal have been estimated at $700 million.The Lummi Nation has pressed the U.S. Army Corps of Engineers to deny the project’s permit because it would disrupt the tribe’s fishing practices. The proposal also has met strong opposition from environmental groups worried about the greenhouse gases and other pollutants produced by burning coal.Cloud Peak Energy bought a 49 percent stake in Gateway Pacific six months ago. The Wyoming company paid $2 million up front to SSA Marine and agreed to cover up to $30 million in permitting expenses, hoping to capitalize on the port to serve growing coal markets in Asia.The deal also included an option for the Crow Tribe to take a 5 percent stake in the port. Cloud Peak plans to build a major mine on the Crow Tribe’s southeastern Montana reservation and planned to move up to 18 million tons of fuel through Gateway Pacific.But the international coal market is experiencing a sudden and drastic decline. Cloud Peak last month took a $58 million loss on its investments in coal export projects including Gateway Pacific.Full article: Backer of proposed coal port stops work amid Lummi Tribe concerns Coal Port-Expansion Sponsor in Washington State Puts Project on Holdlast_img read more

Snowy Owl sightings set record for 2017-18

first_imgConnersville, In. — The Indiana Audubon Society says the winter of 2017-18 will go down in the record books as the highest number of Snowy Owls seen in Indiana in a single winter.  To date, 139 Snowy Owls have been documented in Indiana this winter.  The Indiana Audubon Society has been tracking sightings via submitted reports, social media sites, and birding websites, such as  The new record breaks the old record of 121 owls that were seen during the winter of 2013-14.Snowy owl numbers fluctuate year to year based on their primary prey, lemmings, giant mouse-like rodents, whose population also oscillates based on food supplies and weather conditions in the Arctic.  When populations spike, the owls respond with higher than normal breeding, with some nests containing ten or more eggs.  The subsequent invasions later that fall result in not so much a food scarcity, but because of the abundance of food earlier that summer.  Young owls tend to leave the Arctic each winter, resulting in the larger than normal invasion occurring now.While most winters see a handful of Snowy Owl sightings congregated in the northern part of the state, particularly along Lake Michigan, the current invasion has seen sightings occur nearly statewide, 46 of 92 counties have reported an owl.  Snowy Owls have been as far south as Evansville, with the most sightings near Indianapolis and the open agricultural land to the north and east of the city.“As our wintering Snowy Owls begin to head north over the next month, now is still a good time to keep your eyes out for this amazing sign of the Arctic,” said Brad Bumgardner, executive director for the Indiana Audubon.  “With winter snow melting, these amazing owls are standing out more among the open fields and farmland that they seem to prefer, rather than forests like many other owl species.”Owl seekers are reminded to keep their distance should they find one.  Snowy Owls have little apparent fear for humans, but small stresses and spooking can wear a winter-weary bird down, resulting in lower weights and less of an ability to fly back north in the spring.To learn more about the Indiana Audubon Society and to search for programs and field trips near you, visit them on the web.last_img read more
