Study shows that women’s brains respond more to romantic cues on a full stomach

first_imgShare Share on Facebook You’ve heard that romance starts in the kitchen and not in the bedroom. Well, researchers at Drexel University finally have the science to support that saying – but not the way you might think.In a new study published online in the journal Appetite, researchers found that women’s brains respond more to romantic cues on a full stomach than an empty one. The study explored brain circuitry in hungry versus satiated states among women who were past-dieters and those who had never dieted.The study’s first author Alice Ely, PhD, completed the research while pursuing a doctoral degree at Drexel, and is now a postdoctoral research fellow at the Eating Disorders Center for Treatment and Research, part of the UC San Diego School of Medicine. Michael R. Lowe, PhD, a professor in the College of Arts and Sciences at Drexel University, was senior author. LinkedIn Emailcenter_img Pinterest “We found that young women both with and without a history of dieting had greater brain activation in response to romantic pictures in reward-related neural regions after having eaten than when hungry,” said Ely.Ely said the results are contrary to several previous studies, which showed that people typically demonstrate greater sensitivity to rewarding stimuli when hungry. Such stimuli may include things like food, money and drugs.“In this case, they were more responsive when fed,” she said. “This data suggests that eating may prime or sensitize young women to rewards beyond food. It also supports a shared neurocircuitry for food and sex.”The latest finding, based on a small pilot study, grew from Ely and her Drexel colleagues’ earlier work investigating how the brain changes in response to food cues. Specifically, the researchers looked at whether the brain’s reward response to food differed significantly in women at risk for future obesity (historical dieters) versus those who had never dieted. All of the study participants were young, college-age women of normal weight.In that study, published in Obesity in 2014, the researchers found that the brains of women with a history of dieting responded more dramatically to positive food cues when fed as compared to women who had never dieted or who were currently dieting.“In the fed state, historical dieters had a greater reaction in the reward regions than the other two groups to highly palatable food cues versus neutral or moderately palatable cues,” she said. Highly palatable cues included foods like chocolate cake; neutral cues were things like carrots.Ely said the data suggests historical dieters, who longitudinal studies have shown are more at risk for weight gain, may be predisposed by their brain reward circuitry to desire food more than people who have not dieted.“Based on this study, we hypothesized that historical dieters are differentially sensitive – after eating – to rewards in general, so we tested this perception by comparing the same groups’ brain activation when viewing romantic pictures compared to neutral stimuli in a fasted and fed state,” she said. Testing was done using MRI imaging.While both groups’ reward centers responded more to romantic cues when fed, the historical dieters’ neural activity noticeably differed from the non-dieters in one brain region that had also turned up in the earlier food studies.“The pattern of response was similar to historical dieter’s activation when viewing highly palatable food cues, and is consistent with research showing overlapping brain-based responses to sex, drugs and food,” said Ely.

A new study shows women use gossip to compete for a man’s attention

first_imgShare In this study, 290 heterosexual Canadian students between the ages of 17 and 30 years old completed three questionnaires. One measured how competitive the participants are towards members of the same sex as their own, especially in terms of access to the attention of potential mates. The other questionnaires measured the tendency and likelihood of the participants to gossip about others, the perceived social value of gossip, and whether it is okay to talk about others behind their backs.It was found that people who were competitive towards members of their own sex had a greater tendency to gossip. They were also more comfortable with the practice than others. Women had a greater tendency to gossip than men, and they also enjoyed it more, and saw more value in participating in such chit-chat. Men were more likely to gossip about the achievements of others. Such talk among women often targeted the physical appearance of another, and was used to share social information. Women also found gossip to have greater social value, which may allow them gather more information about possible competitors in the game of finding a mate. It may also help to hone their ability to gossip in future.According to Davis, these findings provide evidence that gossip is an intrasexual competition tactic that corresponds to women’s and men’s evolved mate preferences. It also reflects the different strategies used by the sexes in their quest to find suitable mates.“The findings demonstrate that gossip is intimately linked to mate competition and not solely the product of a female gender stereotype that may be viewed as pejorative,” states Davis, who believes that therapists, counsellors, educators, and the general public should rethink their stance about gossip. “It is a highly evolved social skill essential for interpersonal relationships, rather than a flaw of character.” LinkedIn Pinterest Share on Facebookcenter_img Share on Twitter Although both men and women gossip, women may be more likely to use gossiping and rumour-mongering as tactics to badmouth a potential rival who is competing for a man’s attention. Women also gossip more about other women’s looks, whereas men talk about cues to resource holding (e.g., wealth) and the athleticism of their competitors.According to Adam Davis of the University of Ottawa in Canada, gossiping is a highly evolved social skill and an intrasexual competition tactic that relates to women’s and men’s evolved preferences. He therefore sees it as essential for interpersonal relationships, and not a flaw of character. Davis is the lead author of a study in Springer’s journal Evolutionary Psychological Science that provides the first verifiable evidence for a positive link between intrasexual competitiveness, the amount of gossip that people take part in, and whether they are OK with such talk or not.Scholars agree that gossip has evolved as an efficient way to learn more about others, and to enforce group norms. It is also a method by which people can learn more about their rivals, and can call into question their reputation, especially when they are vying for the same romantically or sexually desirable mates.

Initial tests show no anthrax contamination at CDC labs

first_imgEarly results of environmental tests at labs at the US Centers for Disease Control and Prevention (CDC) where workers were possibly exposed to Bacillus anthracis after a lapse in safety protocols are negative, suggesting contamination or release was unlikely, a spokesman for the agency said today.Benjamin Haynes, senior press officer for the CDC’s infectious disease team, told CIDRAP News that the CDC will continue monitoring the samples until the end of the week before confirming the lack of contamination. He said the affected labs will not be reopened until they have been cleared for safe operation.The CDC’s probe of the incident will conclude in early July, and a US Department of Agriculture (USDA) investigation will go on throughout this week, Haynes said.Report of reassignmentIn other developments, Michael Farrell, PhD, director of the CDC lab involved in the possible anthrax exposure, has been reassigned while the agency investigates the event, Reuters reported today, attributing the information to scientists at the lab who are not authorized to speak on the subject. CDC officials have declined to comment on Farrell’s reassignment, and Farrell has not responded to queries from Reuters.The CDC is monitoring the health of and has offered prophylactic treatment and anthrax vaccination to 84 employees who may have been exposed to B anthracis. Haynes said so far none of them have reported symptoms consistent with infection.Senate requestIn a related development today, a US Senate committee today asked the CDC for information about the lapse in safety protocols that led to the possible exposure, along with steps the agency plans on taking to prevent future incidents. The request came from a bipartisan group of four members of the Committee on Health, Education, Labor, and Pensions.In a letter to CDC Director Tom Frieden, MD, MPH, the committee members said they had serious concerns and questions about the lab’s procedures.”Of additional concern is the fact that the HELP committee, which has jurisdiction over the CDC, the select agent program, and biomedical research generally, did not learn of this incident until nearly after a week after it was detected,” the group wrote. They requested a briefing and written explanation from Frieden.See also:Jun 23 Reuters storyJun 23 Senate HELP committee statementlast_img read more

Above and below for Tappan Zee

first_imgThe final phase involved careful debris removal from the old bridgeThe final phase involved careful deconstruction and debris removal from the old bridge. Adding to the challenge were the accelerated schedule for the project, the sheer size of the bridge, variable water depths of the Hudson River below, and windy conditions. The river flow, tide ranges, water clarity and visibility were also major issues.“As soon as the excavator bucket, clam shell bucket, cutter head on a dredge goes under the water you can no longer see it,” said Lou Nash, president of Measutronics Corporation, an integrator of Trimble Marine technology.Tappan Zee consulted with Lou Nash, the Measutronics team and Trimble to overcome these challenges. The positioning and guidance systems used included Trimble and Teledyne components – Trimble software, hardware, and sensors, and Teledyne marine imaging sonar for subsurface applications. Measutronics calibrated the equipment and installed the systems and all the sensors. With the system calibrated, Measutronics was able to check against the survey and start training the operators on how to use the software. The team also set up the machine in-cab screens and made sure the data flow was accurate.Trimble Marine Construction software was used on all tools across the project for excavation, placement of structures and demolition work. Regardless of the tool being used with the machine – buckets, pincers, shears, hammers, jackhammers – by using the marine software and sonar equipment each had precise guidance.#*#*Show Fullscreen*#*# Tappan Zee Constructors is a consortium between Fluor Enterprises, American Bridge Company, Granite Construction Northeast and Traylor Bros that was hired to design and build New York’s Governor Mario M Cuomo Bridge, one of the USA’s largest single design and build contracts of its kind. The project started in 2013 and the final southbound lanes opened in September last year. Deconstruction of the old bridge continues.#*#*Show Fullscreen*#*# The bridge is one of the US’s largest design and build projects of its kindThe demolition team started by using the system to establish a baseline of conditions in the river. This began with three-dimensional point cloud data collection of submerged features via a survey vessel using sonar.“We’re able to look at the structure beforehand and then take that imagery, evaluate and confirm elevations, quantities and conditions,” said area manager Blake Yaffee.After a baseline was set, Tappan Zee used TMC software and Teledyne SeaBat T20 high resolution multibeam echosounder to create a plan for breaking up the old bridge’s concrete structures into rubble for safe removal from the Hudson River bottom.Using surface data to deal with submerged structuresSurface data was then provided to the various machine types for guidance in deconstructing the submerged structures. TMC software was also used to monitor and visualise deconstruction progress of submerged structures and bridge components. As deconstruction progressed to removal, the survey vessel continually collected data and updated the existing 3D surface model, which was transferred in near real time to the machine fleet.“From our system, what the operator sees in the first phase is where the tool has been so he’s getting proper coverage of the inner deconstruction process,” said Lou Nash.The software follows a traffic light-like pattern, indicated in green on the operator’s control box when excavation is needed and changing colours to yellow as the operator gets closer to grade.The software provides highly accurate locations and visualisation, according to machine operator Andrew Teese. He has been able to retrieve football-sized pieces of concrete which would have been nearly impossible to spot otherwise.“I also have depth, I have the bucket position in two different views, which aided me in locating debris to be removed,” said Andrew.“It gives me a precise location, a ‘bird’s eye view’, and I can position my boom point wherever I want on the image and find whatever was previously scanned.”Blake Yaffee added: “Anybody who has performed underwater demolition is very familiar with the term ‘working in the blind’ because that’s basically what people do.”“For us, the investment in the product against the scale of the project, together with the fact that the sonar and the software can be reconfigured and used on the next project, made it very easy to bring this equipment on.”In addition to quickly identifying and removing debris underwater, precise positioning from TMC and Teledyne has helped Tappan Zee Constructors break up difficult components and material underwater, without relying solely on divers.Scanning the river bottom, the team also identified eroded structures, components and materials that had collected over the years from the old bridge.Tappan Zee Constructors recorded these scans and was asked by the New York State Thruway to remove the material. As a result, the site was returned to the state in a better condition than when the work started.· First published in the September-October 2019 issue of Demolition & Recycling Internationallast_img read more

Burn The Floor

first_imgBurn The Floor – The Rebel Tour. Burn The Floor – The Rebel Tour runs at the Baxter Theatre from Thursday August 8 to Saturday August 17. The original concept of Burn The Floor grew from an electric display of ballroom and Latin dancing at Sir Elton John’s 50th birthday party in London in March 1997. This is where producer Harley Medcalf discovered the ballroom dance world and its charismatic people, with their intensity, commitment and discipline.  Burn The Floor opened in England in 1999. A decade later, after visiting 30 countries and over 160 cities worldwide, it achieved its dream, to bring ballroom to Broadway – appearing at the Longacre Theatre in New York, followed by two seasons in London’s West End. Tickets cost from R180 to R310 through Webtickets or the Baxter Theatre at 0861 915 800.last_img read more

Northern Sydney freight upgrade agreed

first_imgAUSTRALIA: A long-planned A$1·1bn package of enhancements to accommodate more freight on the main line between Sydney and Newcastle has been formally approved.Federal Infrastructure & Transport Minister Anthony Albanese joined NSW Premier Barry O’Farrell at Hornsby station on December 7 to launch the Northern Sydney Freight Corridor Upgrading. This covers several projects on the line between North Strathfield and Hexham, including grade separation at North Strathfield, a third track between Epping and Pennant Hills, additional passing loops near Gosford and a freight holding track at Hexham. Work is expected to get underway in February following the signing of the agreement between the federal government, which will contribute A$840m, and the state of New South Wales which will provide A$214m. Threading freight trains through the Sydney suburban network poses the biggest bottleneck on ARTC’s north-south interstate corridor between Melbourne and Brisbane. Work is already underway on the Southern Sydney Freight Line, which will provide a 36 km dedicated freight track between Macarthur and Sefton. Once the Northern Corridor improvements are completed in June 2016, freight capacity in the corridor will be increased from 29 to 44 trains per day. O’Farrell said that as well as boosting national economic productivity, the work would bring improvements to the reliability of local passenger services. The stations at Concord West and Cheltenham will be rebuilt with improved accessibility. The governments have signed a 20-year agreement guaranteeing access for freight whilst continuing to prioritise commuter service reliability. This was reportedly a major sticking point in the negotiations which have been underway since ARTC first proposed the Strathfield underpass in 2005; the federal government offered four years ago to provide funding in return for guaranteed access. ‘After almost three years of detailed planning and preconstruction activities, we’ve today pressed the “go” button on a project which will help keep Sydney and Australia moving’, said Albanese, noting that a ‘threefold increase in interstate freight volumes’ is projected in the next few years.last_img read more

SBB inaugurates Olten control centre

first_imgSWITZERLAND: Swiss Federal Railways formally inaugurated its regional control centre at Olten on November 17, in a ceremony attended by SBB CEO Andreas Meyer, the president of canton Solothurn Roland Fürst and the Mayor of Olten Martin Wey.BZ Mitte is one of four regional centres that will eventually manage the entire SBB network, under a consolidation programme launched in 2006. BZ West in Lausanne was opened in May 2010, followed by BZ Ost at Zürich Airport in December of that year, and BZ Süd at Pollegio in April 2014.Built at a cost of SFr99m, the new centre is located on a former industrial site close to Olten station. Site clearance began at the end of October 2011, and the foundation stone for the 25 m high building was laid in July 2012. The first workstation went live at the end of 2014, under a phased programme which will see the management of train operations at 190 stations migrated into the new centre by the end of 2017.With a staff of 350, BZ Mitte is replacing 30 separate signalboxes with around 630 staff. It will be responsible for all train operations between Basel, Bern, Brugg and Luzern. According to SBB the centre will eventually control more than 3 000 signals and 2 800 turnouts. By the time the migration has been completed, the railway anticipates that annual train-km operated in the central region will have increased by a further 15%.last_img read more

Spyshot: Another Scrambler Ducati is coming

first_img 2016 Scrambler Ducati Flat Track Pro Firstly, this new addition to the Scrambler line up will reportedly be a more capable off-road bike than the Scrambler Urban Enduro model presently available. More importantly, this new bike will feature a larger 1,078cc air-cooled V-twin powerplant as well.Image source: Bike Social via BenettsDubbed by many right now as the ‘Scrambler 1100 Enduro’, it will slot above the models’ current 803cc and 399cc versions, likely standing as the new range-topper thanks to its larger engine as well. Accompanying that too is a series of improved hardware.Spyshot shows this new Scrambler model primed with inverted or upside-down front forks that appear to longer and have greater travel than the units primed in the other Scrambler models. The front wire-spoked wheels possibly measure in at 21-inch unit with a 19-inch hoop, further hinting this bike’s true mission as an off-roader strongly.Yes, Ducati has already got a purpose-built off-road ride bike in the form of the new Multistrada Enduro. But this new retro-styled Scrambler 1100 Enduro will perhaps slot below the Multistrada Enduro as an affordable alternative from within the storied Italian marque’s stable.Besides this, details are scarce at the moment, and we’ll likely have to wait until either INTERMOT or EICMA later this year to see more of this plus the revived SuperSport tourer too. We’ll definitely have more on this as it develops.Will such a model sit will with hipsters? We aren’t sure. But a Ducati-badged bike capable of going off-road at a much more affordable price and retro styling does hold an appeal. Surely, it will likely rival against BMW and its upcoming R nineT-based retro Adv bike.–Ads– 2016 Scrambler Ducati Icon Six variants may sound like a handful, but apparently not for Ducati and its Scrambler sub-brand.
