Michael Gurian, psychologist and author of “What Could He Be Thinking?“, has claimed to identify approximately one hundred structural differences between male and female brains in a recent study. Gurian comments:

“Men, because we tend to compartmentalize our communication into a smaller part of the brain, we tend to be better at getting right to the issue, the more female brain (will) gather a lot of material, gather a lot of information, feel a lot, hear a lot, sense a lot.“

One major structural difference that Gurian has made clear is that males generally have more activity in the mechanical centers of the brain, while women have more activity in centers of the brain dedicated to verbal communication and emotion. A clear example of this is the hypothetical situation of giving a child a toy. He explains it as such:

“That doll becomes life-like to that girl, but you give it to a two-year-old boy and you are more likely, not all the time, but you are more likely than not to see that boy try to take the head off the doll. He thinks spatial-mechanical. He’s using the doll as an object.“

Another expert, Dr. Marianne Legato, says it all boils down to genetics, noting that the Y chromosome (which only males carry) has “at least 21 unique genes unique to males which control many of the body’s operations down to the level of the cells.”

Gurian agrees that culture is significant in brain development, but argues that biology plays an equally important role. He makes a point of how the MRI scans show that the female corpus callosum, the center of the brain which regulates communication between the brain’s hemispheres, is larger than the male’s. On the other hand, the scans also show that information flows more freely between the hemispheres of the male brain.

The exact role that brain structure plays in behavior, however, has been an area of considerable contention in science for literally hundreds of years. Early studies in craniometry conducted by Paul Pierre Broca were used to attempt to distinguish differences between human races, though have now been dismissed as scientific racism. The nature-nurture debate has raged for centuries in a variety of forms, without yet any clear resolution as to the role in which innate biological tendencies interact with environmental conditions or willed behavior. As such, studies relating to brain structure and claims to innate behavior often generate substantial controversy.

MIT anthropologist of science Joseph Dumit’s study of brain imaging in his book Picturing Personhood: Brain Scans and Biomedical Identity, noted that the apparent “transparency” of such pictures (the appearance that they can be easily interpreted by laymen, when they are often the source of ambiguity and dispute by even highly-trained neurosurgeons) has led to their proliferation as indicators of objective truth in media and in courts of law, and that such conclusions are often knowingly exaggerated by the specialists creating the images for better visual effect.

The timing of Gurian’s book comes on the heels of another controversy over gender differences sparked by comments made by Harvard president Lawrence Summers, who blamed low numbers of women in the sciences on genetic differences. Summers has been criticized by a large number of academics and scientists, as well as by many news publications, in the wake of what he was reported as saying during a conference on January 14.

Studies done on germs and bacteria performed by researchers at the University of Florida show that a dirty kitchen sponge can be cleaned and “sterilized” by microwaving it for 2 minutes, but researchers warn to wet the sponge first.

“People often put their sponges and scrubbers in the dishwasher, but if they really want to decontaminate them and not just clean them, they should use the microwave,” said the professor who was in charge of the study that discovered the results, Gabriel Bitton.

“Basically what we find is that we could knock out most bacteria in two minutes. The microwave is a very powerful and an inexpensive tool for sterilization,” added Bitton.

The sponges that researchers studied, were placed in “raw wastewater” and then put into a microwave to be “zapped,” according to Bitton. The wastewater was a “witch’s brew of fecal bacteria, viruses, protozoan parasites and bacterial spores, including Bacillus cereus spores,” said Bitton.

Researchers say that at least 99% of the bacteria, viruses, spores and parasites in kitchen spongees can be destroyed or “inactivated” by simply microwaving the wet sponge, on the highest power, for two minutes.

The death toll from Wednesday’s plane crash in Taipei, Taiwan reached 40 today with the recovery of five more bodies.

There were 58 on board when TransAsia Airways Flight 235 crashed into the city’s Keelung River. Fifteen survived and three more remain missing. Tzu Chi Foundation volunteer Lee Hung Shu-ying said today cold weather meant the families of the missing believe their loved ones are dead.

The Aviation Safety Council is investigating. The plane was in the air for minutes before banking steeply, hitting an elevated road, and crashing into the river. The domestic flight from Taipei Songshan Airport was headed to the island of Kinmen.

Investigators are focusing on the ATR 72-600’s engines. One engine automatically ‘feathered’ itself. Feathering involves the turboprop’s propeller rotating its blades to reduce drag.

Engines autofeather when they fail (‘flaming out’). By reducing drag on the non-working engine, a twin turboprop plane can fly safely using only its other engine. A feathered engine will not provide any thrust. The reason for autofeathering is presently unclear; what is known is the flight crew subsequently shut off the wrong engine. A series of stall warnings went off in the cockpit as the aircraft headed to disaster.

Aviation Safety Council managing director Thomas Wang confirmed an automated “number two engine flameout” message should have alerted the crew to the engine trouble, leading them to follow “the corresponding checklist”. “There are procedures that pilots go through — safeguards — when you’re going to shut down an engine, particularly close to the ground,” said John M. Cox, former commercial pilot and boss of a safety consultant. “Why that didn’t occur here, I don’t know.”

Stephen Fredrick, a former pilot of similar aircraft, told CNN video showing the final seconds is consistent with dual flameout. He said the wings-level, nose-down position suggested gliding.

Wang, however, cautions it is too early to blame any particular factor. “At this moment we just release the numbers, the parameter we’ve confirmed, we did not release any judgment who did what at this time”. The Aviation Safety Council has teamed up with engine manufacturer Pratt & Whitney Canada to examine the engines.

Also being prioritised is finalising a cockpit voice recorder transcript and cockpit examination. The aircraft was near-new.

Local prosecutors are investigating potential “professional error”, and the Civil Aeronautics Administration has ordered TransAsia retest all ATR pilots. 90 flights over three days are cancelled to allow the proficiency checks. TransAsia and Uni Air have also been ordered to check their collective 22 ATRs for engine and fuel system problems.

Pilot Liao Chien-tsung and his co-pilot, not publicly identified, were initially hailed as heroes by prosecutors, mayor Ko Wen-je, international press, and at least one relative of a survivor. After declaring “Mayday Mayday, engine flameout” to air traffic control the pair grappled with their struggling plane, avoiding buildings in its path.

They have been credited with reducing the death toll. Their bodies were found in the cockpit, with leg fractures. Both were still holding the wrecked plane’s controls.

Viktor Schreckengost, the father of industrial design and creator of the Jazz Bowl, an iconic piece of Jazz Age art designed for Eleanor Roosevelt during his association with Cowan Pottery died yesterday. He was 101.

Schreckengost was born on June 26, 1906 in Sebring, Ohio, United States.

Schreckengost’s peers included the far more famous designers Raymond Loewy and Norman Bel Geddes.

In 2000, the Cleveland Museum of Art curated the first ever retrospective of Schreckengost’s work. Stunning in scope, the exhibition included sculpture, pottery, dinnerware, drawings, and paintings.

Residents of a Leeds, England neighbourhood have requested help from a council because their neighbourhood is plagued by crime, overcrowding, and community tensions.

Leeds City Council received a request for help from residents of Hyde Park, who said they were worried about the increasing level of anti-social behavior and worsening community relations. A report will be unveiled on Wednesday by a council delegation, highlighting the problems in the area. “The people living in Hyde Park come from widely different population groups… these groups have very different customs, needs and living styles and this can provoke high levels of tension in the area,” the delegation said.

The council claims that because of the 28 per cent ethnic minority population and the 40,000 students living in the neighbourhood, there are tensions between residents. They added, however, that they are actively encouraging people to work together, citing a multi-faith forum, a cricket competition and activities which bring old and young together.

The report says that the council are trying to build relationships between Muslims and police, something which they said is “particularly important after the area’s connection to the London bombings on 7th July 2005.” A local newspaper reported that “the Shebab project introduces young Muslims to role models from sport and culture and also runs scholars’ talks to counter extremist ideologies.”

Crime has increased by 7% in the past year in Hyde Park, and residents noted that anti-social behaviour was getting worse. The council said that an anti-burglary task force had helped to reduce the number of thefts from homes. Residents complained that there was a lack of pride in the area, and at the end of the academic year in the summer, large piles of rubbish were left in streets, yards and alleyways. The report adds that the council operates a recycling scheme aimed towards teenagers, and that rubbish collections have increased.

The Guardian reported on Wednesday that campaigners are attempting to “take control of a derelict school building and transform it into a community hub are appealing for sponsors and partners in a bid to turn their dreams into reality.” They say that the unused building, owned by the council, could be used for meetings and events. A volunteer group of residents have been working on a business plan, and have gained support from local businesses to create “a vision of an open, accessible and valuable resource for all.”

A member of the commitee, however, said he was “frustrated” with the council’s attitude towards the plans. “The RPCC is slightly frustrated with certain communication issues that we’ve had with the council, but we’re working with them and hoping to gain further assistance going forward,” he said. “It’s a shame that certain setbacks could have been avoided.”

The deputation added that “a major factor in Hyde Park’s suffering is its high level of population density”, which they conceded is something they are unable to change. The council responded to complaints that streets are “cheap and unhealthy takeaways, letting agents and boarded-up shop fronts,” by saying that Hyde Park Corner and Headingley are, according to the Yorkshire Post, “thriving shopping areas and work had taken place to ensure a good mix of outlets.”

The report concludes: “The council acknowledges that because of the very particular circumstances which exist in the neighbourhood, Hyde Park faces difficult challenges which affect the quality of life of residents and that ‘normal’ service levels may not be sufficient to tackle some of these. The council will do more to enable local people to influence how services work and how local problems are tackled. Local community and voluntary groups will be invited to play an active role.”

A National Academy of Sciences report (.pdf) last year said that while the milk and meat from cloned animals would not likely make anyone sick, more research should be performed. Now, a new US-Japan study published in the April 11 online issue of the Proceedings of the National Academy of Sciences says that milk and meat from cloned cattle does indeed appear to meet industry standards and appears to be safe for human consumption.

As BBC News reports, the scientists, led by Professor Jerry Yang from the University of Connecticut, compared the produce from two beef and four dairy clones, all derived from a single Holstein dairy cow and a single Japanese black bull, with the produce from normal animals of similar age and breed.

The meat was analysed against more than 100 physiological, tissue and cellular components, while the milk was analysed for protein, fat and other variables. No significant differences between the produce of cloned and normal cattle were found. Higher levels of fat and fatty acids were found in the cloned cow meat, but they still fell within beef industry standards.

While the study showed the cloned produce to be within the range approved for human consumption, the scientists stressed that the research was still in its early stages. Their findings, they said, provide “guidelines” for further research with larger numbers of clones from different genetic backgrounds.

Cloning livestock may one day increase yields by copying those animals that are especially productive and especially resistant to disease.

“The milking production levels in the US are three to four times higher than levels in China; maybe even five times or more compared to cows in India and some other countries,” Professor Jerry Yang told BBC News. “Therefore cloning could offer technology for duplicating superior farm animals. However, all the products from these cloned animals must be safe for human consumption. …and it is a major issue for scientists to provide a scientific basis for the data and information to address this question.”

As USA Today reports, there is currently no law governing the sale of meat or milk from the estimated 1,000 to 2,000 cloned farm animals in the USA. But since 2003, the US Food and Drug Administration (FDA) has asked producers to voluntarily keep the meat and milk of these animals, and that of their offspring, out of the food supply.

Wired News reports that companies like ViaGen and Cyagra, which offer livestock-cloning services, have also been waiting for several years for a final say from the FDA.

“For the United States agricultural industry, (cloning) can reduce the number of cows necessary for milking,” said Jerry Yang “They can have a pleasant environment and produce even more milk.” He also said that cloning cattle from the United States, where genetic breeding is more advanced, could save developing countries 50 years of breeding.

The idea of cloning animals for human consumption is not without its critics. First, there are the welfare concerns, as most cloned animals do not make it to term before being born, and many of those that do are born deformed or prone to illness. The Humane Society of the United States has asked for a ban on milk and meat from clones for just this reason. Second, there is still the concern that healthy clones may have subtle defects that could make their food products unsafe to eat.

As the Washington Post reports, some critics are asking why it is necessary to clone cows that produce huge amounts of milk when surpluses, rather than shortages, are the main problem facing the U.S. dairy industry today.

Sunday, April 3, 200528 year old Alex Sanchez, outfielder for the Tampa Bay Devil Rays, is suspended without pay for 10 days for using a performance enhancing drug. Sanchez is the first player to be suspended under Major League Baseball’s new, stricter drug policy.

The Baseball officials and the players’ union have both decided to not disclose the specific substance which tested positive.

Sanchez originally planed an appeal against the ban, but decided against it. He denies taking any performance enhancing drugs and blames the positive test on over-the-counter vitamins, muscle relaxants and protein shakes that he takes, but has not identified any specific medications as of yet.
