Reggie Bibbs is a 43-year-old-man living in Houston, Texas. Mr Bibbs was born with a genetic disease called neurofibromatosis (NF), which causes him to develop tumors on his body (see infobox on the right). NF can be a subtle disease, but in Bibbs’ case it has left him with a disfigured face and deformed leg. But he is happy with the way he looks, and doesn’t want to change his appearance to please other people. He has launched a successful campaign entitled “Just Ask”, and that’s just what Wikinews did in a video-interview.

The interview was prepared by Wikinews reporter Michaël Laurent with the help of Bertalan Meskó (who has a popular genetics and web 2.0 blog). Their questions were sent to a close friend of Mr. Bibbs, Lou Congelio, who kindly conducted the interview.

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.

In a major decision, the Supreme Court of the United States has expanded the right of government to seize private property for public good by allowing the city of New London, Connecticut to invoke eminent domain and seize homeowners’ property for economic development reasons.

In a closely-divided decision, 5–4, the court determined that the city’s economic development plan constituted a “public use”, and therefore qualified under the U.S. Constitution’s fifth amendment’s Eminent Domain clause.

Justice John Paul Stevens wrote the majority decision, and was joined by Justices David H. Souter, Ruth Bader Ginsburg, Stephen G. Breyer and Anthony Kennedy. “Promoting economic development is a traditional and long accepted function of government,” Stevens wrote, and justified the decision further by saying municipal authorities are better positioned to make decisions regarding a community’s best interests than judges.

Writing the dissenting opinion, Justice Sandra Day O’Connor rejected the economic justification as a public use, pointing out that wealthy individuals are more capable of defending themselves and so are less at risk. But the greatest issue was the likelihood of abuse of eminent domain:

“The specter of condemnation hangs over all property. Nothing is to prevent the state from replacing any Motel 6 with a Ritz-Carlton, any home with a shopping mall or any farm with a factory.” A separate dissent was also included written by Justice Clarence Thomas.

Christine Comer, former director of the science curriculum for the Texas Education Agency (TEA), is suing the Commissioner Robert Scott for wrongful dismissal. Comer alleges that she was “illegally fired for forwarding an e-mail about a lecture that was critical of the teaching of intelligent design in science classes.” Her suit alleges she was “terminated for contravening an unconstitutional policy” which required “employees to be neutral on the subject of creationism – the biblical interpretation of the origin of humans.”

The Dallas Morning News reported, “The policy was in force even though the federal courts have ruled that teaching creationism as science in public schools is illegal under U.S. Constitution’s provision preventing government establishment or endorsement of religious beliefs.” Among Comer’s supporters is Philosopher and National Center for Science Education speaker Barbara Forrest who was the presenter at the lecture Comer mentioned in the email.

News 8 Austin reported, “The TEA was not available for comment late Wednesday.”

With two space walks, 78 million miles and six months on board the International Space Station under their belts, Commander-Science Officer Leroy Chiao and Flight Engineer Salizhan Sharipov, the station’s 10th crew, landed in Kazakhstan in a Soyuz spacecraft at 6:08 p.m. EDT Sunday.

Also returning was European Space Agency Astronaut Roberto Vittori of Italy, who launched to the Station with the Expedition 11 crew and spent eight days doing experiments. He was aboard under a contract between ESA and the Russian Federal Space Agency.

The re-entry of the ISS Soyuz 9 spacecraft was perfect, returning the astronauts to Earth 53 miles northeast of the town of Arkalyk after 192 days, 19 hours and 2 minutes in space for the Expedition 10 crew. The recovery team reached the capsule in minutes.

They launched from the Baikonur Cosmodrome in Kazakhstan last Oct. 13 at 11:06 p.m. EDT. During their increment they performed two spacewalks, continued station maintenance and did scientific experiments.

Notable accomplishments included replacing critical hardware in the Joint Quest Airlock; repairing U.S. spacesuits; and submitting a scientific research paper on ultrasound use in space. Chiao was also the first astronaut to vote in the U.S. Presidential election from space. The crew completed two spacewalks, including experiment installation and tasks to prepare the Station for the arrival of the new European Automated Transfer Vehicle next year.

Aboard the Station, Commander Sergei Krikalev and Flight Engineer and NASA Station Science Officer John Phillips, the Expedition 11 crew, are beginning a six-month mission. It will include the resumption of Space Shuttle flights and two spacewalks from the Station. Expedition 11 is scheduled to return to Earth on October 7, 2005. The two latest occupants of the station launched with Vittori from Baikonur April 14.

Krikalev and Phillips will have light duty for the next two days, as they rest after completing a busy handover period. For the past week, they have been learning about Station operations from the two men who called the ship home since October. Chiao and Sharipov briefed Krikalev and Phillips on day-to-day operations and gave them hands-on opportunities at Station maintenance. Chiao and Phillips restored the Quest airlock to working order for future spacewalks and practiced operating the Canadarm2 robotic arm.

While nearly all coverage of the 2008 Presidential election has focused on the Democratic and Republican candidates, the race for the White House also includes independents and third party candidates. These parties represent a variety of views that may not be acknowledged by the major party platforms.

Wikinews has impartially reached out to these candidates, throughout the campaign. We now interview independent Presidential candidate Frank Moore, a performance artist.

New Orleans, Louisiana —After Category 4 storm Hurricane Katrina slammed into New Orleans, on the night before August 29, 2005, several flood control constructions failed. Much of the city flooded through the openings. One of these was the flood wall forming one side of the 17th Street Canal, near Lake Pontchartrain. The U.S. Army Corps of Engineers (USACE) is the primary agency for engineering support during such emergencies. A USACE team was assessing the situation in New Orleans on the 29th, water flow was stopped September 2nd, and the breach was closed on September 5th.
