As the debate over arming teachers in schools reverberates across the country, Kansas is doubling down on the idea.A new bill would not only authorize the arming of Kansas school staff, it would hold schools responsible if a shooting were to occur and the teachers and staff present were not allowed to be armed.Here's the exact wording?from House Bill 2789:"In any action against a unified school district arising out of acts or omissions regarding the possession or use of firearms on the premises of such school district, there shall be a rebuttable presumption of negligence on the part of such school district when it is shown by evidence that such school district did not authorize any employee of such school district, other than school security officers, to carry concealed handguns..."The House bill is causing some serious contention in the Kansas state capitol. During a House Insurance Committee hearing on Tuesday, Rep. Blake Carpenter, one of the bill's authors, quoted the movie "American Sniper" and said violence in school was a matter of "when" and not "if.""It's not if our kids will be killed; it is when they will be killed and what we are doing to prevent it," he said,?according to the Kansas City Star.CNN has reached out to Carpenter for comment.The bill has received significant pushback. A group of protesters was present at Tuesday's hearing, and Rep. Brett Parker, a Democratic opponent of the bill, shared a photo of stacks of papers he says are written testimonies against it.Kansas teachers?are technically already allowed by state law to carry guns on public school campuses as long as they have a permit and meet any school-specific requirements. But according to the Kansas City Star the 2013 legislation caused problems with insurance providers for some of the state's school districts, who refused to extend coverage because of the liability of armed staff.As a result, some districts put their own policies in place, overriding the law and disallowing the concealed carry of weapons on school property.The bill currently before the House committee also addresses this by forbidding insurance companies from refusing coverage just because a school district allows teachers and staff to be armed."No insurance company shall charge unfair discriminatory premiums, policy fees or rates for, or refuse to provide, any policy or contract of real or personal property insurance, liability insurance or policy containing liability coverage for any unified school district solely because such school district authorizes employees of such school district to carry concealed handguns on the premises of schools and attendance centers operated by such school district..." the bill states. 2742

As one of the world's most famous prehistoric monuments, Stonehenge still holds many secrets despite centuries of study. For the first time, new research is lifting the veil on the people who are buried at Stonehenge.The study was published in the journal Scientific Reports on Thursday.Much of the previous research around the monument in Wiltshire, England, has centered around how or why Stonehenge was built -- not the people buried there or who built it.But studying the human remains at Stonehenge is no easy task. In addition to dating back to 3,000 BC, the remains were also cremated. During the early phase of Stonehenge's history, it largely served as a cemetery.Fortunately, lead study author Christophe Snoeck, post-doctoral researcher at the Vrije Universiteit Brussel, combined his passions for archeology and chemical engineering to pioneer developments in archaeological analysis.The results revealed that 40% of the people buried at Stonehenge likely came from west Wales, the suggested origin of the site's smaller bluestones, and they most likely helped transport the stones and build Stonehenge. Signals from the bone analysis suggested that within the last ten years of their lives, these people were not living at Stonehenge nor originally from the area around Stonehenge, known as the Wessex region."Our results are the first one to provide direct evidence on the origin of those buried at Stonehenge, shedding light on the importance of the site in the Neolithic landscape," Snoeck said in an email. 1531

Astrophysicist and author Neil deGrasse Tyson has denied allegations of sexual misconduct made against him by three women.Last month, three women told Patheos, a religion and spirituality website, that Tyson harassed them and made inappropriate sexual advances as early as 1984 and in recent years."Accusations can damage a reputation and a marriage. Sometimes irreversibly. I see myself as loving husband and as a public servant -- a scientist and educator who serves at the will of the public. I am grateful for the support I've received from those who continue to respect and value me and my work," he wrote in a lengthy Facebook post titled "On Being Accused."Tyson disputed or offered a different version of the allegations against him.Katelyn N. Allers, an associate professor of physics and astronomy at Bucknell University in Pennsylvania, told Patheos that Tyson grabbed her arm and reached into her dress while looking at her tattoo of the solar system. She said the incident happened during a party after a gathering of the American Astronomical Society in 2009. 1081

ATLANTA — The long-standing dispute over voting rights and election security has come to a head in Georgia.The state's messy primary and partisan finger-pointing offer an unsettling preview of a November contest when battleground states could face potentially record turnout.According to The Associated Press, many Democrats are blaming Georgia's Republican governor, Brian Kemp, and Republican secretary of state, Brad Raffensperger, for hours-long lines at polling stations. Republicans are blaming local Democratic officials in Atlanta, particularly in areas with large numbers of racial minorities, which saw some of the longest lines in the state.Georgia's Tuesday elections were plagued with a series of problems caused by the coronavirus pandemic, which forced the closure of dozens of polling stations across the state. Fewer polling stations resulted in long lines at stations that remained open.The pandemic also caused an increase in requests for absentee ballots — which some voters claimed they never received. Some of those voters then stood in line for hours hoping to cast an in-person ballot, only to be told they could not because they had requested a mail-in ballot that they never received.The election was further exacerbated by the use of new voting machines, which some precincts had trouble operating. Some polling stations had trouble turning on or logging into machines, and voters were forced to stand in line while workers waited for technical support.As of Wednesday morning at 7:30 a.m. ET, many races of national importance were still too close to call, with only 24% of the state's 2,354 voting precincts reporting complete results. In the Democratic Senate primary, John Ossoff held 46% of the vote — short of the 50% he needed to win to avoid a runoff in August.The election issues raise the specter of a worst-case scenario: a decisive state, like Florida and its "hanging chads" and "butterfly ballots" in 2000, remaining in dispute long after polls close.That would give President Donald Trump, presumptive Democratic presidential nominee Joe Biden, and their supporters a chance to offer competing claims of victory or raise questions about the election's legitimacy, further dividing an already roiled electorate. 2260

ATLANTIC CITY, N.J. (AP) — The federal government is warning Americans to brace for a "floodier" future.Government scientists predict 40 places in the U.S. will experience higher than normal rates of so-called sunny day flooding this year because of rising sea levels and an abnormal El Nino weather system.A report released Wednesday by the National Oceanic and Atmospheric Administration predicts that sunny day flooding, also known as tidal flooding, will continue to increase."The future is already here, a floodier future," said William Sweet, a NOAA oceanographer and lead author of the study.RELATED: Devastating 'ARk' storm envisioned for California by U.S. Geological SurveyThe report predicted that annual flood records will be broken again next year and for years and decades to come from sea-level rise."Flooding that decades ago usually happened only during a powerful or localized storm can now happen when a steady breeze or a change in coastal current overlaps with a high tide," it read.The nationwide average frequency of sunny day flooding in 2018 was five days a year, tying a record set in 2015.But the East Coast averaged twice as much flooding.The agency says the level of sunny day flooding in the U.S. has doubled since 2000.Nationwide, the agency predicted, average sunny day flooding could reach 7 to 15 days a year by 2030, and 25 to 75 days a year by 2050.RELATED: How to check if your neighborhood is at risk of flooding"We cannot wait to act," said Nicole LeBoeuf, acting director of NOAA's Ocean Service. "This issue gets more urgent and complicated with every passing day."Global sea levels are rising at a rate of about 3 millimeters a year, or about an inch every eight years, according to Rutgers University researchers, who predict that by 2050, seas off New Jersey will rise by an additional 1.4 feet (0.4 meters).The study noted floods interfering with traffic in northeast states, swamping septic systems in Florida and choking Delaware and Maryland coastal farms with saltwater over the past year.Baltimore experienced 12 days of high-tide flooding from 1902 to 1936. Within the last 12 months, it experienced an additional 12 days.Robert Kopp, a leading climate scientist with Rutgers University, who was not involved in the study, said it confirmed many well-established trends."It's simple arithmetic: If you have higher sea level, you will have tides causing flooding," he said. "We're not talking about disaster flooding. We're talking about repetitive flooding that disrupts people's lives on a daily basis. It's sometimes called 'nuisance flooding,' but it has real impacts and costs."RELATED: Mega storm could cause billions in damage to California, report showsThe report cited the disruption of commerce in downtown Annapolis, Maryland, where parking spaces are lost to flooding. A 2017 study put the price tag on lost economic activity at as much as 2,000. The water table has risen to ground level and degraded septic systems in the Miami region, and farmlands in the Delmarva Peninsula in Delaware and Maryland have been damaged by salt water encroaching into planted areas.High-tide flooding is causing problems including beach erosion, overwhelmed sewer and drinking water systems, closed roadways, disrupted harbor operations, degraded infrastructure and reduced property values — problems which "are nearly certain to get much worse this century," the report read.The report's statistics cover May 2018 through April 2019.The agency forecasts sunny-day flooding this year in Boston at 12 to 19 days (it had 19 last year). It predicted sunny-day flooding this year in New York (8 to 13 days, compared with 12 last year); Norfolk, Virginia (10 to 15 days; compared to 10 days last year); Charleston, South Carolina (4 to 7 days, compared to 5 last year); Pensacola, Florida (2 to 5 days compared with 4 last year); Sabine Pass, Texas (6 to 13 days compared with 8 last year) and Eagle Point, Texas (29 to 40 days, compared to 27 last year).West coast predictions included San Diego (5 to 9 days compared to 8 last year); Los Angeles (1 to 4 days compared to 5 last year); Humboldt Bay, California (6 to 12 days compared to 12 last year); Toke Point, Washington (9 to 21 days compared to 12 last year) and 2 to 6 days in Seattle, compared to 2 last year.The report documented that 12 locations broke or ties their record of sunny day flooding last year, including 22 in Washington, D.C., 14 in Wilmington, North Carolina; and 12 each in Baltimore and Annapolis.FEMA created flood maps of San Diego County which enable users to search by their address.
