Kule kwetu Tanga hivi vimgahawa viko kibao na uwa na chakula kizuri sana. Hapa utapata wali wa nazi na mandondo(maaragwe) na samaki wa kukaanga kwa bei poa kabisa, lakini tatizo ni kuhusu suala nzima la kiafya. Na sidhani kwamba hawa kina mama ntilie wanakuwa na leseni na hivyo hata suala la kuwakagua linakuwa halipo kabisa.

South African law recognizes traditional polygamous marriages, even President Jacob Zuma has three wives. Yet while polygamy remains common among several tribes including the Zulus and Swazis, simultaneous weddings are rare.

The United States will impose travel bans on Kenyan ministers and other prominent people blocking government reforms aimed at preventing political violence, the American ambassador to Kenya said Thursday.
Michael Ranneberger said that 15 Kenyans had received letters saying the U.S. was reviewing its relationship with them. He declined to name the individuals, but said that when the ban is imposed their names will be made public.
The top U.S. diplomat for Africa, Johnnie Carson, sent the letters to ministers, senior government officials and members of parliament, Ranneberger said.
The U.S., one of Kenya's key lenders, has persistently criticized Kenya for not taking action against perpetrators of postelection violence in 2007.
More than 1,000 people were killed in December 2007 and early 2008 following a dispute over presidential election results.
President Mwai Kibaki and Prime Minister Raila Odinga signed a power-sharing deal in February 2008 to end the violence, which was also fueled by frustration over poverty and corruption.
The power-sharing deal also contained clauses on constitutional, judicial and other reforms, which have not been implemented.
"It's a growing sense of frustration, at the highest levels (in the U.S. government), that despite the rhetoric, and commissions and talk and all that, not much has happened," Ranneberger told journalists in the Kenyan capital.
Kenyan government spokesman Alfred Mutua told The Associated Press that Kenya does not, "respond to activism diplomacy."
Kwa kina mama wa Kiafrika, kubeba mzigo kichwani ni kitu cha kawaida kabisa na ni mojawapo ya utamaduni uliotanda Afrika yote. Sina uhakika ni matokeo ya baadae baada ya kuwa wanabeba hii mizigo kwa kipindi kirefu. Je! kuna madhara yeyote yanayotokana na zoezi hili kwa afya za hawa kina mama? Wataalamu mnatuambiaje kwenye hili?
A World first: Vaccine helps prevent HIV infection.
For the first time, an experimental vaccine has prevented infection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible.
The vaccine cut the risk of becoming infected with HIV by more than 31 percent in the world's largest AIDS vaccine trial of more than 16,000 volunteers in Thailand, researchers announced Thursday in Bangkok.
Even though the benefit is modest, "it's the first evidence that we could have a safe and effective preventive vaccine," Col. Jerome Kim said in a telephone interview. He helped lead the study for the U.S. Army, which sponsored it with the National Institute of Allergy and Infectious Diseases.
The institute's director, Dr. Anthony Fauci, warned that this is "not the end of the road," but said he was surprised and very pleased by the outcome.
"It gives me cautious optimism about the possibility of improving this result" and developing a more effective AIDS vaccine, Fauci said in a telephone interview. "This is something that we can do."
Even a marginally helpful vaccine could have a big impact. Every day, 7,500 people worldwide are newly infected with HIV; 2 million died of AIDS in 2007, the U.N. agency UNAIDS estimates.
"Today marks an historic milestone," said Mitchell Warren, executive director of the AIDS Vaccine Advocacy Coalition, an international group that has worked toward developing a vaccine.
"It will take time and resources to fully analyze and understand the data, but there is little doubt that this finding will energize and redirect the AIDS vaccine field," he said in a statement.
The Thailand Ministry of Public Health conducted the study, which used strains of HIV common in Thailand. Whether such a vaccine would work against other strains in the U.S., Africa or elsewhere in the world is unknown, scientists stressed.
"This is a scientific breakthrough," Thai Health Minister Witthaya Kaewparadai told a news conference in Bangkok. "For the first time ever there is evidence that HIV vaccine has preventative efficacy."
The study actually tested a two-vaccine combo in a "prime-boost" approach, where the first one primes the immune system to attack HIV and the second one strengthens the response.
They are ALVAC, from Sanofi Pasteur, the vaccine division of French drugmaker Sanofi-Aventis; and AIDSVAX, originally developed by VaxGen Inc. and now held by Global Solutions for Infectious Diseases, a nonprofit founded by some former VaxGen employees.
ALVAC uses canarypox, a bird virus altered so it can't cause human disease, to ferry synthetic versions of three HIV genes into the body. AIDSVAX contains a genetically engineered version of a protein on HIV's surface. The vaccines are not made from whole virus — dead or alive — and cannot cause HIV.
Neither vaccine in the study prevented HIV infection when tested individually in earlier trials, and dozens of scientists had called the new one futile when it began in 2003.
"I really didn't have high hopes at all that we would see a positive result," Fauci confessed.
The results proved the skeptics wrong.
"The combination is stronger than each of the individual members," said the Army's Kim, a physician who manages the Army's HIV vaccine program.
The study tested the combo in HIV-negative Thai men and women ages 18 to 30 at average risk of becoming infected. Half received four "priming" doses of ALVAC and two "boost" doses of AIDSVAX over six months. The others received dummy shots. No one knew who got what until the study ended.
All were given condoms, counseling and treatment for any sexually transmitted infections, and were tested every six months for HIV. Any who became infected were given free treatment with antiviral medicines.
Participants were followed for three years after vaccination ended.
Results: New infections occurred in 51 of the 8,197 given vaccine and in 74 of the 8,198 who received dummy shots. That worked out to a 31 percent lower risk of infection for the vaccine group.
The vaccine had no effect on levels of HIV in the blood of those who did become infected. That had been another goal of the study — seeing whether the vaccine could limit damage to the immune system and help keep infected people from developing full-blown AIDS.
That result is "one of the most important and intriguing findings of this trial," Fauci said. It suggests that the signs scientists have been using to gauge whether a vaccine was actually giving protection may not be valid.
"It is conceivable that we haven't even identified yet" what really shows immunity, which is both "important and humbling" after decades of vaccine research, Fauci said.
Details of the $105 million study will be given at a vaccine conference in Paris in October.
This is the third big vaccine trial since 1983, when HIV was identified as the cause of AIDS. In 2007, Merck & Co. stopped a study of its experimental vaccine after seeing it did not prevent HIV infection. Later analysis suggested the vaccine might even raise the risk of infection in certain men. The vaccine itself did not cause infection.
In 2003, AIDSVAX flunked two large trials — the first late-stage tests of any AIDS vaccine at the time.
It is unclear whether vaccine makers will seek to license the two-vaccine combo in Thailand. Before the trial began, the U.S. Food and Drug Administration said other studies would be needed before the vaccine could be considered for U.S. licensing.
Also unclear is whether Thai volunteers who received dummy shots will now be offered the vaccine. Researchers had said they would do so if the vaccine showed clear benefit — defined as reducing the risk of infection by at least 50 percent.
Those issues, plus how to proceed with future studies, will be discussed among the governments, study sponsors and companies involved in the trial, Kim said. Scientists want to know how long will protection last, whether booster shots will be needed, and whether the vaccine helps prevent infection in gay men and injection drug users, since it was tested mostly in heterosexuals in the Thai trial.
The study was done in Thailand because U.S. Army scientists did pivotal research in that country when the AIDS epidemic emerged there, isolating virus strains and providing genetic information on them to vaccine makers. The Thai government also strongly supported the idea of doing the study.
Libyan President Moamer Kadhafi tosses a book towards Asha-Rose Migiro (L), United Nations Deputy Secretary General and Ali Abdussalam Treki (R), President of the General Assembly during his speech in the United Nations General Assembly at UN headquarters in New York. Kadhafi berated Western powers Wednesday in a UN diatribe, accusing the global body of failing to prevent millions of deaths.

Usafiri wa baisikeli ni muhinu sana katika hizi nchi zetu za kimasikini. Ukweli ni kwamba zinawarahisishia sana watu katika kufanya shughuli zao bila gharama kubwa. Sioni ni kwanini tusiwe na viwanda zaidi ya kimoja ili kutosheleza mahitaji huko vijijini. Kwa kweli wakati wa likizo yangu Bongo nilikutana na wanafunzi wanaotembea mwendo mrefu kwenda na kurudi mashuleni na pengine kama kungekuwa na uwezekano wa upatikanaji wa mabaisikeli ya bei nafuu kungepunguza sana hii karaha.
