Neuroscientists tell Wikinews about empathy and harm aversion observed in lab rats

Thursday, April 30, 2020

In findings published last month in the journal Current Biology, neuroscientists from the Netherlands Institute for Neuroscience examined harm aversion in laboratory rats for conspecifics — rats not wanting to hurt other members of the same species — and reported which region of the brain was crucial for it. Wikinews caught up with Dr Christian Keysers and Dr Valeria Gazzola, two of the authors who contributed to the paper.

For the experiment, the rats were put in a container with two levers. The rats were trained to develop a preference for one of the two levers: each delivering one pellet of sucrose. One of the two levers was harder to press.

After developing a preference, the preferred lever was wired to deliver a shock to another rat in a neighbouring compartment, while delivering a single pellet of sucrose. The study showed the actor rat, which pressed the lever tend to switch the lever to avoid shocking the other rat. The rat receiving the shock was called a victim rat.

Aversion of harm to fellow rats was reported to be equal in both male and female rats. If the actor rats were previously exposed to the shocks, their degree of harm aversion for others was heightened, the study revealed.

The investigation reported the rats avoided pressing the preferred lever to shock another rat, even if that lever delivered two sucrose pellets and the no-harm lever delivered only one. However, this was not the case when the rats were given three pellets by the shock lever. Most of the actor rats did not switch when they received three pellets pressing the lever, which also delivered an electric shock. Dr Gazzola called it a “tipping point” and said it was a “cost-benefit” function.

The study also revealed the importance of the anterior cingulate cortex (ACC) region of the rat’s brain for harm aversion. The scientists tested harm aversion for conspecifics in the rodents after deactivating the ACC using muscimol. Muscimol was injected in the rats belonging to the test group, while saline water was injected to rats in the control group. The observations showed without the active ACC due to muscimol, the active rats in the test group were no longer averse to harming the victim rats, but degree of harm aversion did not drop in the control group rats.

Grand Canyon West Rim Bus Tours 8 Reasons Why You Should Take One

By Keith Kravitz

The #1 day trip from Las Vegas? The West Rim bus tour to the Grand Canyon. It is no surprise, either. This in-demand excursion is packed with activities and attractions, making it a favorite with families, groups, and independent travelers alike. If you haven’t booked this tour yet, here are eight reasons why you should:

1. The West Rim is closes to Las Vegas. Just 120 miles east, the rim can be reached in 2.5 hours by bus.

2. See Hoover Dam and the new bypass bridge. En route to Grand Canyon West, you will go over the new bridge, a fabulous structure that lifts you 900 feet above the Colorado River. Views of the dam don’t get better than this, either.

3. You get to experience the Grand Canyon Skywalk. Known as the Glass Bridge, the Skywalk is Las Vegas’ hottest natural attraction, taking you 70 feet past the edge of the Canyon and dangling you 4,000 feet above the Colorado River.

4. Take a helicopter ride to the bottom. The west rim is the only place in the entire Grand Canyon where you can do this. The 4,000-foot descent is incredible. Enjoy a Champagne toast at the base.

5. Go river rafting. Board a rapids-ready pontoon boat for a ride down the river. This is a great upgrade to the helicopter descent package. Prepare to catch some “spray” on these currents.

6. Experience real Native American culture. Grand Canyon West is on the Hualapai Indian Reservation and managed by the Tribe. Interact with tribal members and explore an authentic Indian village.

7. Cheaper and easier than renting a car. Self-drive and you will pay for gas, car rental, car insurance, and a host of Park fees, including parking and Park pass. The west rim bus is all-inclusive. No surprises.

8. There are Seven Natural Wonders of the World, including the Grand Canyon, and it’s the only one that exists in the U.S.

West rim bus trips are all-inclusive and include free hotel shuttle service and a BBQ lunch. These trips are ONLY conducted aboard state-of-the-art luxury motor coaches. These buses feature lounge-style seats, over-sized windows, TV’s, climate-controlled cabins, and quiet-ride suspensions. Your driver is a certified professional and will also serve as your knowledgeable guide.

There are several variations of the West Rim bus tour. The most popular includes the Grand Canyon Skywalk, followed by the helicopter descent to the bottom. Pontoon boat rides are seasonal, and usually run from March to Late November. These tours require a full day and will have you back in Las Vegas by late afternoon.

This trips are a great deal. Prices start at $94. If you upgrade you package, the cost goes up accordingly. For example, if you bundle the Grand Canyon Skywalk, you are looking at around $129 per person. The prices I’m quoting are from Grand Canyon Coaches. They are promotional and only available on the company’s website. Try to reserve your trip in advance as these tours sell out quickly.

The West Rim bus tour is a phenomenal deal that no Las Vegas traveler should pass up. Think about it. For under $100, you can experience one of the most famous landmarks in the United States and the planet. If you want more canyon, do the Grand Canyon Skywalk or take a helicopter ride to the bottom. The rim is just a 2.5-hour bus trip from The Strip, making it the ultimate daytime escape for people of all ages. So hop aboard! Let’s “do” the rim!

Former U.S. President Gerald Ford hospitalized

Thursday, October 12, 2006

The office of Gerald Ford said Thursday that the former United States President was admitted to Eisenhower Medical Center for tests in Rancho Mirage, California.

“President Gerald Ford has been admitted to Eisenhower Medical Center in Rancho Mirage, California for medical tests. He is doing well,” Ford’s spokeswoman Penny Circle said. The statement didn’t release any information about the tests.

Ford has been hospitalized twice this year. In January, he was hospitalized to treat pneumonia. In July, he was hospitalized at Colorado’s Vail Valley Medical Center due to shortness of breath.

Ford was also hospitalized in August at the Mayo Clinic in Minnesota for heart procedures. Ford received a pacemaker to regulate his heartbeat. Ford also underwent angioplasty to increase blood flow in his arteries. Ford also suffered a small stroke five years ago.

Gerald Ford became the 38th United States President on August 9, 1974 after Richard Nixon resigned due to the Watergate scandal. At the age of 93, Ford is the oldest living U.S. President and could next month become the longest living U.S. President ever.

Queues form outside struggling UK bank; calm urged

Saturday, September 15, 2007

Nervous savers have re-formed queues this morning outside many branches of Northern Rock, after the £2.68 billion bank took an emergency loan from the Bank of England, the UK central bank.

Shares in the bank had dropped 25% by lunchtime yesterday in London – and stood nearly 60% lower from their high of February – after the Bank of England acted in its capacity as “lender of last resort” to provide Northern Rock with short-term financing to enable it to continue operations.

The Bank of England hasn’t acted as lender of last resort since 1973, when the collapse of Cedar Holdings – a pioneer of second mortgages to UK home-owners – threatened a crisis in the country’s banking industry.

Northern Rock has been hit hard since June this year by the turmoil in world credit markets. Although only 0.24% of its assets are exposed to subprime US housing debt, the bank’s business model saw it grow its loan book by 43% in the first six months of this year. Rather than lending money deposited with it by savers, Northern has borrowed aggressively in the short-term capital markets.

“Northern Rock is not a reckless lender,” said Angela Knight, head of the British Bankers Association on national radio this morning. Urging the bank’s savers not to withdraw their money in panic, “the mortgage lending it does well and it does in a high quality, high calibre way,” she added.

But savers queuing to withdraw their money from Northern Rock today said they were “horrified” by the Bank of England needing to step in.

“I am going to take out the lot, every penny,” said one Northern Rock saver to Bloomberg as he queued outside the bank’s West End branch in London.

Students compete in second international Neurosurgery Olympiad in Tyumen, Russia

Monday, May 6, 2019

The second International Student Olympiad in Neurosurgery for the prize of the Governor of Tyumen Oblast, Russia took place in the first week of April at the Federal Center for Neurosurgery in Tyumen. The competition was attended by 46 people from cities within Russia as well as from Aktobe, Kazakhstan. Wikinews attended the event, and talked to some of those involved.

This was the second consecutive student Olympiad in neurosurgery. Six of the country’s eight federal district capitals were reportedly scheduled to send contestants. The winners are awarded free tuition at the academic department of Neurosurgery at First Moscow State Medical University (First MSMU), also called Sechenov University.

Madina Bizheva, in her fourth year at Kabardino-Balkarian State University, won this second Olympiad. The other two places at Sechenov University were awarded to Oleg Titov, fifth year at the First MSMU, and Irina Borovikova, fifth year at Ural State Medical University. Bizheva said: “I give my victory to my mother, who inspired me to study at a neurosurgeon. After she had a stroke, the dream of becoming a doctor began to turn into reality. I was seriously preparing for the Olympiad. One hand rocked the child, the other held a book on neurosurgery. If a person strives for and desires something, then everything will work out.” ((ru))Russian: ????? ?????? ? ???? ????, ??????? ?????????? ???? ????? ?????? ?? ????????????. ????? ????, ??? ? ??? ???????? ???????, ????? ????? ?????? ????? ???????????? ? ??????????. ? ???????? ?????????? ? ?????????. ????? ????? ?????????? ???????, ?????? ??????? ????? ?? ?????????????. ???? ??????? ? ???? ?????????? ? ????-?? ????? ??????, — ??? ?????????.

The chairman of the organizing committee of the Olympiad and the head physician of the center, Albert Sufianov, is also the head of the academic department of neurosurgery in the First MSMU. The three best performers in this contest are awarded the opportunity to study for free in his department in the residency of the Sechenov University.

The event was supported financially by Tyumen Oblast. The new governor of the region, Alexander Moor, during his message to the regional parliamentarians read out on November 22, just offered to diversify the economy, reducing the focus on oil and gas from the third Baku and cultivating medical tourism: “Now the annual volume of our exports — non-row materials and non-energy — has come close to a billion dollars. In the next year, this must be given priority. And here, too, non-standard approaches will be required, in which trends of various origins will organically merge across the traditional industry nomenclature. For example, it is time to perceive Tyumen medicine as a full-fledged export-oriented industry, while closely associated with the tourism business. Medical tourism is growing rapidly all over the world, and in terms of price and quality, Tyumen is more than competitive — if not on a global scale, then on a scale of the whole continent Eurasia exactly. Here the themes of several national projects intersect at once!” ((ru))Russian: ??????? ??????? ????? ?????? ???????? – ??????????? ? ????????????????? – ???????? ??????????? ? ????????? ????????. ? ????????? ???? ???? ??? ???? ?????. ? ??? ???? ??????????? ????????????? ???????, ? ??????? ?????? ???????????? ?????????? ???????????? ????????? ?????????? ?????? ?????????? ?????????????. ??????, ????????? ???????? ??? ???? ???????????? ??? ??????????? ?????????-??????????????? ???????, ??? ???? ????? ????????? ? ????????????? ????????. ??????????? ?????? ????? ?????? ?? ???? ????, ? ?? ?????????? ???? ? ???????? ?????? ????? ??? ?????????????????? – ???? ?? ? ?????????? ????????, ?? ? ???????? ????? ???????????? ?????????? ?????. ????? ???????????? ???????? ????? ?????????? ???????????? ????????!

According to Professor Sergey Dydykin, who is both co-chairman of the organizing committee and head of the academic department of operative surgery and topographic anatomy of the First MSMU, in the United States and Europe it is not customary to teach manual skills, such as manual surgical techniques, to undergraduates; conducting surgical competitions for students is a Russian practice.

During the Olympiad, students had to perform simulated practical tasks. For example, in the final part of the competition, the contestants had to mill away the shell of a raw egg without damaging the membranes beneath. This exercise simulates endoscopic drilling.

According to Sufianov, the Olympiad shows young people the “social elevators” available to them. He suggesnted student Ibrahim Salamov as an illustration of his words. A year ago, this native of the Dagestan village took first prize, and he is now one of the organizers of the Olympiad.

Regarding which part of the competition was most difficult for aspiring neurosurgeons, Sufianov said it was English language. From his view, this is a nationwide problem in Russia — there are many skilled surgeons in the country, but their knowledge of foreign languages is not very strong. In his opinion, a specialist has almost no chance to become a very high level professional without knowledge of English.

Alexander Gagay of Yekaterinburg, who took third place last year, is currently a fourth year student at Ural State Medical University. This year, he said, he came to support his fellow Yekaterinburgers. In his opinion, the most difficult part was the theoretical tasks, and not English. In his view, the federal neurosurgery centers like Tyumen created within the framework of the national health project are on the same level with their foreign counterparts. In his view, there are strong opportunities to become a very good specialist without leaving Russia.

Several people returned to the Olympiad after attending last year. One is Denis Kovalchuk, a sixth year student at Buryat State University. He said he was interested in neurosurgery from the first year, but in his home region there are no suitably equipped facilities as there are in Tyumen. Kovalchuk also said that, after the first Olympiad, a community of young neurosurgeons emerged on social networks, numbering about 400 people. Students exchange professional literature in it and give each other tips for use in practical situations.

This year, the jury decided two participants in addition to the official winners performed at such a high level and Albert Sufianov provided them with his personal grant for residency training at First MSMU. These were Ivan Shelyagin and Valentina Sidorenko from Tyumen State Medical University.

Latent Semantic Indexing

Submitted by: Carmine Hjort

LSI, or latent semantic indexing, is what all the search engines use these days. It is a new type of indexing that weights key words as well as related key words. Latent semantic indexing is a good way for Google or another search engine to index documents because it makes sure the documents that come up in a search are meaningful for the key word. Latent semantic indexing results in more helpful documents for the person who submitted the search engine query.

Google and other search engines used to not use latent semantic indexing for their search. The documents with the strongest key words matches would resulting in higher indexing. Because latent semantic indexing wasn’t being used, all the document had to have was a high key word count. Information in the document didn’t matter and the query and search was nearly pointless. But now, using latent semantic indexing a search engine can use not only key words but related key words to rank documents in a search return and the documents can actually have pertinence to the key word subject.

[youtube]http://www.youtube.com/watch?v=ST5FyIUCkBA[/youtube]

Latent semantic indexing is the best way to provide good search results for a search query. A search engine like Google is using latent semantic indexing and you can easily and quickly find the information you need. Everyone uses Google, and Google uses latent semantic indexing. A search engine goes through a lot of documents online and then searches them for a key word count to see how its analysis is compared to other documents with the same key word. The higher the key word count, the better, before latent semantic indexing. But now a search engine will take into account other factors. How many LSI terms, or related key words, the document has is also very important when the search engine is indexing documents.

Latent semantic indexing is a great tool for search engines like Google who try to provide good information for the world. But marketing people need to know how to make their website or documents show up with a higher rating to the search engine. Just filling a document with key words doesn’t trick latent semantic indexing. You have to write relevant articles that pertain to the topic of the website, with plenty of related key words. Then you website and documents can show higher on a search engine query.

It is really genius how latent semantic indexing goes through a document and counts how many hits there are of each word. That analysis is then reported back to the search engine so that it can show results to the person who had the query. The more key words, the better. But that’s not all. You have to have related key words at a high count as well for latent semantic indexing to choose the document.

Latent semantic indexing, or LSI, is used by many search engines, and even Google so marketing had better know that key words aren’t the only words that count in a document anymore.

Retired U.S. vets sue Donald Rumsfeld for excessive service cutbacks

Tuesday, May 31, 2005

One thousand residents of the Defense Department-managed Armed Forces Retirement Home in Washington, D.C. filed a class-action lawsuit on May 24, asserting that the cut-backs in medical and dental services imposed by Secretary of Defense Donald Rumsfeld are illegal. The operating budget for the home was reduced from $63 million in 2004 to $58 million for 2005. The residents cite cuts in on-site X-ray, electrocardiogram, physical and dental services, and the closing of the home’s main clinic and an on-site pharmacy.

Chief Financial Officer Steve McManus responded that the changes not only save money but also achieved improved efficiencies. “We’re really trying to improve the benefits to our residents,” he said.

Most of the home’s costs are paid for by a trust fund and monthly fees paid by residents. By law, the Armed Forces Retirement Homes are required to fund, “on-site primary care, medical care and a continuum of long-term care services.”

Candidates make campaign stop at trade fairs ahead of 2008 Taiwan Presidential Election

Friday, November 9, 2007

Thursday, November 8, two trade shows, named MEDIPHAR Taipei at the Taipei World Trade Center (TWTC) and Taipei Audio Video Fair at the TWTC and The Grand Hotel, opened in Taipei, Taiwan. Some politicians and government officials chose these events as an opportunity to promote their parties and campaign-coalitions ahead of the 2008 Taiwan Presidential Elections.

From the incumbent Pan-Green Coalition, President of the Republic of China Chen Shui-bian, Premier of Republic of China Chang Chun-hsiung, and spokesman for the Executive Yuan Jung-tai Cho visited the two shows successively and were innundated by Taiwanese media. President Chen avoided answering questions on the hot topic of commodities prices, addressing only those about the medical industry development, overseen by Sheng-mao Hou, Minister of Health.

From the Pan-Blue Coalition, 2008 vice-presidential candidate, and former Premier, Vincent Siew participated the opening of the Taipei Audio Video Fair at The Grand Hotel. He criticized on the economy policy and remarked: “The ruling party [DPP] doesn’t have a good track record, and some industries weren’t be supported in timely manner so that they lost some opportunities. I sincerely hope the government can appropriately assist the audio and video industries in marketing good brands and products to the world.”

Also, current Democratic Progressive Party legislator Wang Shih-chien was invited to give a violin performance and sing a Taiwanese song. The events at the Taipei World Trade Center proved to be quite a platform for the candidates running in the 2008 Taiwan Presidential Elections.

‘Mobile phone dermatitis’ linked to nickel deposits

Friday, October 17, 2008

The British Association of Dermatologists (BAD) has released a report saying that an illness they named ‘mobile phone dermatitis’, in which individuals owning a cell phone have developed a rash on the side of their face, is likely linked to nickel deposits in the metal of some cellular phones. Nickel has been known to cause rashes on those who have a sensitivity to, or are allergic to the metal. Nickel is also mixed with other metals to make jewelry.

The Association says that the condition is likely to affect people who spend too much time talking on the phone. They found that those who spend too much time text messaging or talking for long periods on the phone, were most likely to develop a rash, sometimes severe, on their face and ears, or the tips of their fingers.

Tests in January, performed on 22 cellular phones by scientists at Brown University in Rhode Island located in the United States, had found that just under half, a total of 10, contained nickel while the rest had rubber buttons and a plastic case. Initially the rashes were unexplained, and researchers could not find a reason why so many individuals began to experience the symptoms. In most cases the rashes were untreatable.

“Cell phones intended for rugged use … often have rubber coating and no surface nickel. Those with more fashionable designs often have metallic accents and are more likely to contain free nickel in their casings,” said Lionel Bercovitch MD., one of the researchers, in a report in the journal for the Canadian Medical Association on January 1, 2008.

Researchers also state that although some people may not be allergic to nickel, “prolonged” and continuous exposure to it can cause severe reactions.

“Prolonged or repetitive contact with a nickel-containing phone is more likely to cause a skin reaction in those who are allergic,” said BAD dermatologist Dr. Graham Lowe in a press release. In the United Kingdom alone, BAD says nearly 30% of the population suffers from rashes brought on by prolonged exposure to the metal.

The researchers also recommend individuals to buy swab test kits to test for traces of nickel.
