Getty ImagesIrene Corsaro will never forget her first driving lesson under a rain of black ash from Mount Etna. Like many Sicilians from Catania, the 18-year-old has learnt quickly how to make her way home on a road covered in volcanic dust during one of the volcano's 11 eruptions in the past three weeks. A 12th eruption was under way on Friday.Every so often, the volcano's four main craters awake with intense, simultaneous blasts. These episodes create a spectacular natural firework display, replete with bubbles, fountains and flows of lava. Within minutes, neighbouring towns and villages are showered with flakes of ash and other debris.'Lava falling on my roof'Irene's trip with her mother through the deserted streets of her home town of Nicolosi, on Etna's slopes, turned into a nightmare...

Repeated head impacts, brain injury increase risk for depression, study finds

Health
June 26 (UPI) -- Head injuries experienced while young may increase a person's risk for depression and dementia decades later, according to a study published Friday by the journal Neurology. In general, those with a history of repetitive head impacts scored 1.24 points higher on a 15-point depression symptom scale than those without a history, the researchers found. Advertisement Study participants with a history of traumatic brain injury, or TBI, had scores up to 0.75 points higher, they said. "The findings underscore that repetitive hits to the head, such as those from contact sport participation or physical abuse, might be associated with later-life symptoms of depression," study co-author Michael Alosco said in a press release. "It should be made clear that this association is likely...

Jan. 18 (UPI) -- Researchers reported Thursday that repeated hits to the head, including in sports and on the battlefield, lead to chronic traumatic encephalopathy, or CTE -- even without a concussion.The team, led by Dr. Lee Goldstein, published the findings in the journal Brain after a seven-year study. Researchers from Boston University, where Goldstein works, as well as scientists from the Cleveland Clinic, Harvard Medical School, Lawrence Livermore National Laboratory in California, Ben-Gurion University in Israel and Oxford University contributed to the study.A number of high-profile athletes have developed the Alzheimer's-like disease but it's also been found in service members hurt in roadside bombs and other blasts."Most hits to the head are not concussive... but no one is paying ...
Why North Korea hasn't launched a missile in 56 days despite repeated tests

Why North Korea hasn't launched a missile in 56 days despite repeated tests

World
Though President Donald Trump is on a high-profile visit to Asia this week, North Korea has refrained from testing another ballistic missile or nuclear bomb, making this the longest stretch of time since Trump took office that the regime has not conducted a test. Is it a sign the administration's approach to North Korea is working, even as Washington and Pyongyang continue to exchange volleys in a war of words? North Korea tested its first missile just 22 days after Trump was inaugurated on Jan. 20. From March to May, the regime conducted tests every one to two weeks. It has been 56 days since North Korea's last test of a ballistic missile, an intermediate-range KN-17 that flew over the Japanese island of Hokkaido. As Trump has made his way through South Korea, Japan and China this we...
