MORE STUDY URGED ON CONCUSSIONS IN YOUNG ATHLETES
WASHINGTON (AP) -- No one knows how often the youngest athletes suffer concussions. It's not clear if better headgear is the answer, and it's not just a risk in football.
A new report reveals big gaps in what is known about the risk of concussion in youth sports, especially for athletes who suit up before high school.
The Institute of Medicine and National Research Council on Wednesday called for a national system to track sports-related concussions and start answering those questions.
Despite a decade of increasing awareness of the seriousness of concussions, the panel found young athletes still face a "culture of resistance" to reporting the injury and staying on the sidelines until it's healed.
"Concussion is an injury that needs to be taken seriously. If an athlete has a torn ACL on the field, you don't expect him to tape it up and play," said IOM committee chairman Dr. Robert Graham, who directs the Aligning Forces for Quality national program office at George Washington University.
"We're moving in the right direction," Graham added.

EARTH-SIZE PLANET FOUND WITH ROCKY CORE LIKE OURS
CAPE CANAVERAL, Fla. (AP) -- Scientists have found a planet way out in the cosmos that's close in size and content to Earth - an astronomical first.
But hold off on the travel plans. This rocky world is so close to its sun that it's at least 2,000 degrees hotter than here, almost certainly too hot for life.
Astrophysicists reported Wednesday in the journal Nature that the exoplanet Kepler-78b appears to be made of rock and iron just like Earth. They measured the planet's mass to determine its density and content. It's actually a little bigger than Earth and nearly double its mass, or weight.
Kepler-78b is located in the Cygnus constellation hundreds of light-years away. Incredibly, it orbits its sun every 8 1/2 hours, a mystery to astronomers who doubt it could have formed or moved that close to a star. They agree the planet will be sucked up by the sun in a few billion years, so its time remaining, astronomically speaking, is short.
More than 1,000 exoplanets - worlds outside our solar system - have been confirmed so far.
NASA's Kepler Space Telescope, used to discover Kepler-78b, has identified 3,500 more potential candidates. The telescope lost its precise pointing ability earlier this year, and NASA has given up trying to fix it.
Scientific teams in the United States and Switzerland used ground observatories to measure Kepler-78b.
NSA BROKE INTO YAHOO, GOOGLE DATA CENTERS
WASHINGTON (AP) -- The National Security Agency has secretly broken into the main communications links that connect Yahoo and Google data centers around the world, The Washington Post reported Wednesday, citing documents obtained from former NSA contractor Edward Snowden.
A secret accounting dated Jan. 9, 2013, indicates that NSA sends millions of records every day from Yahoo and Google internal networks to data warehouses at the agency's Fort Meade, Md., headquarters. In the last 30 days, field collectors had processed and sent back more than 180 million new records - ranging from "metadata," which would indicate who sent or received emails and when, to content such as text, audio and video, the Post reported Wednesday on its website.
The latest revelations were met with outrage from Google, and triggered legal questions, including whether the NSA may be violating federal wiretap laws.
"Although there's a diminished standard of legal protection for interception that occurs overseas, the fact that it was directed apparently to Google's cloud and Yahoo's cloud, and that there was no legal order as best we can tell to permit the interception, there is a good argument to make that the NSA has engaged in unlawful surveillance," said Marc Rotenberg, executive director of Electronic Privacy Information Center. The reference to `clouds' refers to sites where the companies collect data.
The new details about the NSA's access to Yahoo and Google data centers around the world come at a time when Congress is reconsidering the government's collection practices and authority, and as European governments are responding angrily to revelations that the NSA collected data on millions of communications in their countries. Details about the government's programs have been trickling out since Snowden shared documents with the Post and Guardian newspaper in June.
