An earthquake of 6.4 magnitude has shaken parts of Mexico, causing buildings to sway in the capital.
The US Geological Survey said it was centred near the town of Tecpan de Galeana in southern Guerrero state, about 190 miles (300km) south-west of Mexico City.
It was also felt in the resort city of Acapulco, the Associated Press says. There are no reports of any damage or injuries but frightened office workers ran into the streets in the capital.

Less Nutritious Grains May Be In Our Future
In the future, Earth's atmosphere is likely to include a whole lot more carbon dioxide. And many have been puzzling over what that may mean for the future of food crops. Now, scientists are that some of the world's most important crops contain fewer crucial nutrients when they grow in such an environment.
The data come from that have been set up to see how crops will perform as levels of carbon dioxide in the air soar past 500 parts per million. (The current level is around 400 ppm.)
These experiments are operating in various parts of the world, and have included test plots of rice, wheat, peas and other crops.
9/11 Illness Kills More Cops Than Attack
The names of police officers who died from ground zero-related illnesses now outnumber the 60 killed in the 9/11 attacks engraved on the New York State Police Officers' Memorial in Albany.
The names of 20 officers have been added to the black granite memorial. They include 12 New York City officers and one from suburban Peekskill who died from illnesses connected to the attack. That raised the total to 71.
According to authorities, the 13 died from cancers attributed to rescue and recovery work at the collapsed World Trade Center towers in Manhattan.
Universe evolution recreated in lab
An international team of researchers has created the most complete visual simulation of how the Universe evolved.
The computer model shows how the first galaxies formed around clumps of a mysterious, invisible substance called dark matter. It is the first time that the Universe has been modelled so extensively and to such great resolution.
The research has been published in the journal Nature.
UPS delivers government drone to random person
The odds of receiving part of a $350,000 government drone in the mail are very slim.
But Reddit user Seventy_Seven got just that. He posted images of the contents of a UPS package Monday that contained wings and a control panel.
"Did I just get a drone in the mail?" Seventy_Seven wrote.
The wrongly delivered box, which was sent to an address in New York, came with a card stating it was the property of the National Oceanic and Atmospheric Administration's aircraft operations center in Tampa.
New report: Climate change has 'moved firmly into the present' and nation needs to adapt
Saying that climate change has “moved firmly into the present,” a federal scientific panel Tuesday released a report cataloging the impacts of such changes, saying some would actually be beneficial “but many more are detrimental.”
The American Southeast and Caribbean regional is “exceptionally vulnerable” to rising sea levels, extreme heat events, hurricane and decreased water resources, the report said. Seven major ports in the region are vulnerable. And residents can expect a significant increase in the number of hot days – defined as 95 degrees or above – as well as decreases in freezing events.
The Next Frontier In The GOP War Over Science
The Obama administration and the scientific community at large are expressing serious alarm at a House Republican bill that they argue would dramatically undermine way research is conducted in America.
Titled the “Frontiers in Innovation, Research, Science, and Technology (FIRST) Act of 2014," the bill would put a variety of new restrictions on how funds are doled out by the National Science Foundation. The goal, per its Republican supporters on the House Science, Space and Technology Committee, would be to weed out projects whose cost can't be justified or whose sociological purpose is not apparent.
Oklahoma earthquakes tied to oil, gas work
The U.S. and Oklahoma Geological Surveys said an increase in earthquakes in the state may be attributed to heightened oil and gas activity.
USGS said it examined the rate of increase in earthquakes in Oklahoma and found they weren't due to random fluctuations in seismic activity in that state.
The joint study found injecting wastewater underground can lead to pressure increases that may contribute to earthquakes.
"Much of this wastewater is a byproduct of oil and gas production and is routinely disposed of by injection into wells specifically designed and approved for this purpose," USGS said.
New Report Documents Chemical Disasters and Environmental Injustice in the U.S.
Americans who face the greatest threat from potential toxic chemical disasters are predominantly from low income and minority communities, a new report released by the Environmental Justice and Health Alliance asserts.
In a first-of-its-kind study, the report, Who’s in Danger? A Demographic Analysis of Chemical Disaster Vulnerability Zones, documents the high-risk factors of living within the vicinity of chemical facilities—including water and wastewater treatment facilities, power plants, bleach production facilities, petroleum refineries and paper mills. The report dubs these hotspots “vulnerability zones,” or “fenceline zones.”
