Sexual preference chemical found in mice

first_imgHealthLifestyle Sexual preference chemical found in mice by: – March 24, 2011 Tweet 33 Views   no discussions Share Sharing is caring!center_img Share Share A chemical in the brain controls sexual preference in mice, according to scientists in China.Male mice bred without serotonin lose their preference for females, a report in Nature says.The researchers say it is the first time that a neurotransmitter has been shown to play a role in sexual preference in mammals.Experts have warned about the dangers of drawing conclusions about human sexuality.The research team first bred male mice whose brains were not receptive to serotonin.A series of experiments demonstrated that these mice had lost the preference for females shown by unmodified males.When presented with a choice of partners, they showed no overall preference for either males or females.When just a male was introduced into the cage, the modified males were far more likely to mount the male and emit a “mating call” normally given off when encountering females than unmodified males were.Similar results were achieved when a different set of mice were bred. These lacked the tryptonphan hydroxylase 2 gene, which is needed to produce serotonin.However, a preference for females could be “restored” by injecting serotonin into the brain.The report concludes: “Serotonergic signalling is crucial for male sexual preference in mice. This is the first time, to our knowledge, that a neurotransmitter in the brain has been demonstrated to be important in mammalian sexual preference.”HumansSexual behaviour in mice is thought to be driven by their sense of smell.Professor Keith Kendrick, a neuroscientist at the Babraham Institute in Cambridge, said: “In terms of having potential relevance to understanding human sexual preference/orientation, we are of course far less influenced by odour cues in this context than mice are.“There is some very limited evidence for altered responses to selective serotonin uptake inhibitors (SSRIs) in the brains of homosexuals, but we have been using psychoactive drugs which either increase or decrease serotonin function for quite some time now, and while effects on sexual arousal, impulsivity and aggression have often been reported, no effects on sexual preference/orientation have.“At this time therefore any potential links between serotonin and human sexual preferences must be considered somewhat tenuous.”Source: BBC Newslast_img read more


Red Bank School Superintendent to Retire at End of Month

first_imgRED BANK – Superintendent of Public Schools Dr. Laura Morana has submitted notice to the school board that she will retire at the end of the month.Morana was in her eighth year with the district. Her last day will be Sept. 30.The timing of her retirement is unusual in that it is occurring at the start of the school year. Her announcement was not included on the board’s posted agenda.When asked about the timing, board President Ben Forest declined to comment calling it a “personnel matter.”He said Morana had informed the board prior to her public announcement.During Wednesday’s board meeting the board began setting up a strategy to replace Morana. “We are going as quickly as we can to find a replacement for Dr. Morana. In the meantime, we will be looking for an interim superintendent.”Forest said it is expected that the district will hire an interim superintendent from outside the district.“The board is pleased with the legacy and record that Dr. Morana has left us,” Forest said. “The board gave her an ovation last night.”Red Bank Mayor Pasquale Menna said he was “saddened to see Laura go. But at the same time I am extraordinarily grateful that she has been able to devote seven years of her life to Red Bank and in that time brought a level of excellence and accomplishment that had never been experienced by us in the past.“Dr. Morana raised the bar and challenged students, parents and guardians, teachers, administrators and staff to achieve new levels of excellence.  For that I am thankful,” Menna said..last_img read more

Crooked Scientists Get Rehab

first_imgFor those who trust scientists, it may come as a shock that some bad apples are getting rehab.Violations of scientific ethics have skyrocketed over the last decade.  Plagiarism, falsifying data, outright fraud – these and other examples of ethical breaches have produced some notable scandals.  What should be done?  Nature on January 8 reported about a new program to rehabilitate the bad apples:With the rapid growth of misconduct cases, some scientists are worried that preventative training in research ethics might not be enough. Nor will it be possible simply to dismiss all violators from science. Scientific rehabilitation, they say, will have to become a necessary tool for research-integrity offices.This seems to be a new problem.  The US Office of Research Integrity received double the complaints from 2011 last year.  Why is that?  It’s another question, not addressed in the article.  The focus is on whether rehab works, and whether bad scientists deserve a second chance.The hero of the article is James Dubois (Saint Louis University), who is trying to make saints out of sinners with his nifty RePAIR program (Restoring Professionalism and Integrity in Research). “We believe that if we can equip them with certain skills, they can return to the field as very productive individuals,” he said.  Through information, informal discussions and management programs, he processes his students and funnels them back into the mainstream with a certificate of completion to potentially fool their managers.No conflict of interest there.  Dubois’ program has a $500,000 grant behind it from the National Institutes of Health, and Dubois charges $3,000 per penitent.  Let’s hope when Dubois teaches about “self-serving biases” on day one, he does it righteously.  A program like this might have more credibility if it were taught by a volunteer or a respected clergyman known for his integrity.For more articles on scientific misconduct, search on “fraud” or peruse the category “Politics and Ethics”.We hope rehab works with some, but isn’t it just like liberals to prefer rehab over punishment?  Some of Dubois’ inmates may have misappropriated thousands of taxpayer dollars, ruined others’ reputations, or garnered fame from fraud.  Dubois believes the really bad apples are only 10-15% of the ones caught.  “There there, Dr. Liar, let’s just have a group chat session to see why you committed that crime.  You couldn’t help it; it was your selfish genes.  Darwin made you do it.”What these scientists need is repentance and conversion.  Give skills to a crook, and you make him a more skillful crook.  Some of the graduates of RePAIR could easily fake penitence then take the information they gathered back to the lab, having learned how better to avoid getting caught.  Without a genuine change of heart, why not?  Dubois is not teaching repentance.  He seems to be building self-esteem.This story underscores the need for righteousness in science.  As with any other field of human endeavor, science cannot work without honest practitioners.  You cannot trust any conclusion from a scientific enterprise that condones (or doesn’t recognize) unethical behavior.  Science requires honesty and integrity—eternal values that cannot evolve.  There’s only one world view that can defend a foundation for true ethical behavior; the Judeo-Christian world view.

Water Quality Status Report issued by Ohio Farm Bureau

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Addressing the challenges that threaten Ohio’s clean water resources is an important priority for the agriculture community. The Ohio Farm Bureau Federation (OFBF) has released a report detailing its efforts to ensure safe and healthy water for the state.The Water Quality Status Report provides a list of action items being taken by farmers, Farm Bureau and many collaborative partners to implement new farming techniques and best practices to protect water while farming productively. It emphasizes actions in the Western Lake Erie Basin (WLEB), but water quality is a statewide issue and Farm Bureau is addressing it throughout the state. Farm Bureau also has established statewide partnerships to identify comprehensive solutions to complex water issues.“Normally, water is something we all take for granted, unless we have too much of it or not enough,” said Steve Hirsch, OFBF president. “Water quality and quantity has always been important to farmers, but they are also vital to the quality of life for all Ohioans.”The Toledo water crisis and the recent algae bloom events in Lake Erie and Grand Lake St. Mary’s prompted swift action by OFBF’s Board of Trustees to make sure that farmers in the major watersheds were doing their part to help to protect water quality in Ohio, thus creating the Water Quality Action Plan.“We committed over $1 million of our member funds to water quality efforts,” Hirsch said. “We have also been encouraging farmers throughout the state and especially within the Western Lake Erie Basin to comply with Senate Bill 150 to complete their fertilizer applicator certification 2 years ahead of the 2017 state law requirement and then to go above and beyond that requirement to create a nutrient management plan for their farms.”Ohio’s largest farm organization is also increasing their commitment to Healthy Water Ohio, a statewide coalition of water users, business groups and environmental interests that are creating a strategic plan for water over the next 20 to 30 years in Ohio.Greg LaBarge, an Ohio State Extension Agronomy Field Specialist, has been very involved with outreach and educational efforts for Ohio farmers. Ohio State’s College of Food, Agriculture and Environmental Sciences has a long history of working with farmers on natural resource and environmental issues such as Ohio’s water quality. One of the latest outreach efforts is a program called “Field to Faucet.”“This effort is taking a very close look at what we are doing from an agricultural standpoint and looking at the watershed in total, through the stream system and into Lake Erie’s Western Basin”, LaBarge said. “We are also thinking about what is happening to the water as it reenters the systems for citizens to use.”Education is another aspect to cleaner water in The Buckeye State.“With Senate Bill 150, a new program focusing on fertilizer applicator certification was developed,” LaBarge said. “Since September of 2014, we have trained 6,429 people across the state in 110 different meetings in all 88 counties. That effort will be ongoing as we work to meet that 2017 state law deadline.”The collaboration of the state’s agricultural organizations with The Ohio State University and Ohio Soil and Water Conservation Districts is something that Farm Bureau Executive Vice President, Jack Fisher, is very proud to highlight.“There has been a lot of work done when it comes to water quality, but there is a lot more to do and it will take a lot of time to do it,” Fisher said. “As we solve one or two things, more things may be brought to our attention and those issues will be added to our list to find solutions to. This is a big, complex issue and it will take time.”There will also be the challenge of finding the balance between improving the water in Ohio and producing enough grains and oilseed to not only keep farms profitable, but to also feed an ever-growing population.“Let’s not forget that as we talk about water quality and water management, we also take for granted food and food production,” Fisher said. “So as we go forward, our policy initiatives in water quality and food production have to be in collaboration and not in isolation.”last_img read more
