but now, new research from boston university and the lawrence livermore lab suggests that concussionsl signal of long-term brain damage known as chronic traumatic ensep lop this. >> you don't have to be concussed to get chronic traumatic ensep lop this. they're distinct. >> reporter: william and his team at the lawrence livermore lab used powerful super computers to image data from impact experience on animals. they discover blows to the skull are enough to cause stress damage to the brain even without causing a concussion and a separate study recently deceased athletes impacts may trigger cte. >> that's important what it means is, for say the people that love football, american football, which is mostly everybody, that concussion protocols may be insufficient to protect the athlete, there is something extra that might have to be done. >> reporter: cte can only be diagnosed after death with an autopsy on the brain. researchers are working to identify markers in the body that could lead to early detection in living yatathletes >> coming up fancy food show introducing the next big trend

federal workers will be furloughed including employees that government laboratories such as lawrence livermorehe slac national accelerator lab at stanford. we called out to transportation, it will be open during daytime hours and may not be open at night. law enforcement agencies in the military will stay on duty. social security and medicare systems continue to operate since they do not rely on annual funding approval by congress. we will get mail and federal courts remain open for the time being. using revenue from fines and fees. our survey asks, should democrats link the funding bill to the dream act? the results were dead even. we also asked 500 adults statewide who you think is most to blame for the potential shutdown of the federal government? democrats and republicans in congress got 22% each.>>> a strong show for support of immigrants and the south bay. massive ads on buses. one country, one future. city leaders gathered this morning to reveal the campaign which will highlight services -- services available to the community. it resulted in 21 bay area arrests. >>> kaiser permanente na

the break through was averagized by these supercomputers at the lawrence livermore lab. >> you don't to get cte and vice versa, they're totally distinct. that was really unknown, but we have shown that pretty conclusively. >> and it doesn't take years of pounding. the boston university researchers studied the brains of fourteen age athletes who died after head injuries. they found changes in the brain within 24 hours of the trauma. it's not just athletes, veterans exposed to bombs. researchers are working on ways to detect it in the living hoping to discover potential treatments and we'll have more on the study and the it implications for your young athlete coming up on abc7 "news at 6:00." >> it just gets scarier and scarier with cte. >>> residents and environmentalistal groups say they're studying a downtown city block that they say contains a toxic chemical. the city wants to rezone a site of fourth and johns treat. but today the neighbors and trade groups set to block the move, they claim the ground is contaminat contaminated. unearthing the toxins would put the city and workers

a team of researchers from the lawrence livermore national lab assisted a team at boston university withmined the brains of four teenaged athletes who either died from their injuries or committed suicide. researchers found that it was anaccumulaon of smaller hits to thhead that caused their injuries, not concussions. earlier on the "four on 2", we talked to one of the scientists involved in the study. >> you never are going to mitigate it completely. and thinking youcan stop playing football completely is probably irrational. but we have a better understanding of how to prevent concussion and -- and -- and the origin of the chronic traumatic encephalopothy so it leads to diagnostics and therapies. >> researchers say the findings are important because all the attention has been on preventing concussions which in the end may not prevent traumatic brain injuries from happening. >>> problem after problem, it started with a mistaken missile alert but the problems didn't stop there. the timeline and new information on the botched missile warning that created widespread panic in hawaii. >> also

i see a deputy drove from lawrence livermore lab, other lab leaders. i'm curious about that. you talk about data analytics, greater and greater data needs, modeling and simulation. my other hat at the council i'm thinking high-performance computing capabilities. the shared national infrastructure we have in our national laboratories that probably are already engaged with you or perhaps could be engaged more. i would love to hear your thoughts around what do you see as some of the tools that might be available that you already are using, or perhaps need better access to to actually do the work. we talk about smart cities, as you said, not just about this but everything connected, these things draining more energy. it's a huge challenge. >> we're working with so many technology providers today. silicon valley and otherwise, that are working on aggregation of customer loads, aggregation of system data to be able to really provide capacity benefits so you don't have to build that next generation facility. those are the kinds of things working. i'll give you an example. there's a
