Egypt Says Cairo Police Kill Suspect In Benghazi Consulate Attack

CAIRO - Egyptian official sources say a militant suspected of involvement in the deadly U.S. consulate attack in Benghazi was killed in clashes in Cairo.

An Egyptian interior ministry source told CBS News on Thursday that the suspect in Egypt, known only by his first name, Hazem, was killed after neighbors summoned police about a suspicious resident. Security forces came in and exchanged fire with the man, before he blew himself up.

The news comes a day after AP reported charges filed against a Tunisian man who was arrested in Turkey this month with reported links to the same attack last month that killed four U.S. embassy employees.

Suspect Ali Harzi was repatriated on Oct. 11 by authorities in Turkey and was charged this week with "membership of a terrorist organization in a time of peace in another country."

Although Harzi is not is not considered to be one of the ring leaders of the Benghazi attack, AP reports that his court dossier links him to the Sep. 11 attack on the U.S. consulate that left Ambassador Christopher Stevens and three other Americans dead.

The communication fiasco surrounding the Benghazi killings remains a thorn in President Obama’s reelection campaign. Secretary of State Hillary Clinton cautioned that a newly released series of e-mails sent by the State Department during the attack on the U.S. consulate in Libya was "not in and of itself evidence" that the administration had assessed the assault as a terrorist attack from the beginning, despite describing it as a protest gone awry five days later.

The account of the Benghazi tragedy has become a campaign target for Republican challenger Mitt Romney and GOP lawmakers, who accuse the White House of misleading Americans about the nature of the attack.

How A "Climatic Memory" Gene Helps Trees Face Environmental Threat

Humans and animals have strategies to deal with their surroundings, including the impacts of climate change. But what about trees? Researchers in Spain have identified mechanisms in plant life to learn over time from unfavorable environmental situations.

How A "Climatic Memory" Gene Helps Trees Face Environmental Threat

Tree brain?

OVIEDO — When it doesn't rain, humans look for water under rocks. Throughout history, we have developed more or less effective techniques (and more or less respectful of the environment) to always have something to drink. Reservoirs, wells or desalination plants help us, when available, to cope with periods of drought.

Animals also have strategies to deal with lack of water, such as moving (sometimes long distances) in search of new reserves or reducing hydration needs by lowering physical activity.

But how does a tree survive?

These living beings are anchored to the same place, where they spend tens, hundreds and even thousands of years. For this reason, their strategies to deal with stressful situations, such as a drought, a heat wave or a plague, are very different from those of animals.

New research has discovered something incredible: trees have a kind of climatic memory in their genes.
