With miniature magnets within themselves, the so-called magnetotactic bacteria are the ones able to navigate their environment using Earth's magnetic
field as a reference.

Arash Komeili, an associate professor of plant and microbial biology Nike Odyssey React Women's Casual Arctic Pink White , and his colleagues at UC Berkeley initially found the repurposing of a deactivated enzyme in one
species, Magnetospririllum magneticum.

However, when the researchers looked throughout the three largest families of magnetotactic bacteria, they found independent occurrences of the same story.

"We really thought that something this unusual would have evolved only once Nike Odyssey React Black Women's ," said graduate student David Hershey. "That just isn't the case. It really just cements how unusual this process is."

A key feature of building magnetic particles is a protease - an enzyme that chews up proteins for recycling - that is deactivated.

The findings, based on X-ray crystallographic images and reported in this week's issue of the journal PLOS Biology, suggest that the scaffold protein,
called MamO Nike Odyssey React Desert Sand Sail Pink Women's , may guide iron atoms into position in the magnetite crystal lattice.

It demonstrates how evolution uses existing molecules for new functions.

The process for animals to build minerals is known as biomineralization. Magnetotactic bacteria, for example, snatch iron atoms and assemble them into
magnetic nanoparticles, or tiny crystals of the mineral magnetite Nike Epic React Flyknit Pure Platinum Black Blue Women's , that connect with their nervous system.

"We would like to know how minerals are built in nature since they constitute a fundamental survival strategy for many organisms," Komeili said.

Knowing what is going on with bacteria, researchers may one day use the tricks to build unique magnetic minerals in a test tube that are otherwise not
possible.

UNITED NATIONS, March 31 (Xinhua) -- UN Secretary-General Ban Ki-moon on Thursday expressed his shock over latest allegations of sexual abuse by
international forces in the Central African Republic (CAR) as new information
surfaced on such crimes committed between 2013 and 2015 by UN and non-UN
personnel.

A UN delegation was sent to the CAR to gather more information on new allegations of sexual exploitation and abuse.

UN spokesperson Stephane Dujarric told a daily briefing that so far 108 alleged victims have been interviewed in the area. "The vast majority of the
cases unfortunately do involve minors Nike Epic React Flyknit Blue Women's ," he noted.

Ban said in a statement that he was shocked to the core by the allegations and that focus should be given to women and young children who have been
"traumatized in the worst imaginable way."

Code Blue, a campaign of the civil society group AIDS-Free World aiming to end impunity for UN peacekeeping personnel, published on its website that 98
girls in a province of CAR reported to the UN that they had been sexually abused
by international peacekeepers.

Moreover, the group said three girls told a UN human rights officer that they were tied up and undressed inside a camp by a military commander from the
Sangaris force Nike Epic React Flyknit Women's Grey White , the French military intervention in CAR, and forced to be involved in bestiality.

The Sangaris force was operating under the authorization of the Security Council but not under UN command.

"The exact number and nature of these extremely troubling allegations are still being determined," said Dujarric. "Allegations made against the French
Sangaris forces in the same area are also being investigated."

The UN Security Council urged Thursday full and urgent investigations into these allegations and said "those responsible should be held accountable."

Ismael Abraao Gaspar Martins, Ambassador of Angola and president of the Security Council in March Nike Epic React Flyknit Women's Cargo Khaki Black Green , told reporters here that the French authorities said they will investigate into the allegations
and will report to the Council.

On March 11, the UN Security Council adopted a resolution to take strong action to combat the problem of sexual exploitation and abuse committed by
peacekeepers since the United Nations has been under mounting pressure as the
allegations against peacekeepers continue to surface.

The resolution requests UN Secretary-General to replace all military and police unit of a troop or police contributing country in UN peacekeeping
operations if the country has not taken appropriate actions to investigate their
personnel or hold perpetrators accountable.

Earlier this month, the UN published a report saying the total number of allegations received of sexual abuse in the UN system in 2015 was 99. Among them
69 took place in countries where?? peacekeeping operations and 22 were in CAR.

"These crimes only fester in silence," said Ban Nike Epic React Flyknit Women's Pink Red , while stressing that member states "who alone have the power to discipline their forces with consequences"
must take actions.

UN General Assembly President Mogens Lykketoft said on Thursday he is appalled by allegations by "the very people meant to protect civilians and
vulnerable populations in conflict and post conflict situations," while the High
Commissioner for Human Rights, Zeid Ra'ad Al Hussein, called the latest
allegations as "sickening."

The General Assembly president also said he is going to hold an informal hearing in the 193-member General Assembly on this matter.

On Wednesday Nike Epic React Flyknit Black Grey Women's , the UN Department of Field Support formally notified the permanent UN missions of all 193 member states of
the establishment of the "Trust Fund in Support of Victims of Sexual
Exploitation and Abuse", urging them to consider voluntary financial
contributions.

"The contributions will be used to provide medical, legal and psycho-social assistance to victims and children born as a result of sexual exploitaeuclidean
