Scientists believe they have discovered a new species of whale in Mexico.The team was taking underwater video and audio samples of three beaked whales near Baja California. They work with the Sea Shepherd Conservation Society near the San Benito Islands, about 300 miles from the U.S. border.They originally were looking for what animal was making an unidentified sound recorded in 2018 in the area.Experts in the field of beaked whales now say the scientists’ observations don’t match anything seen before, and they are “highly confident” the video shows an entirely new species, according to a press release.“We saw something new. Something that was not expected in this area, something that doesn’t match, either visually or acoustically, anything that is known to exist,” said Dr. Jay Barlow in a statement from the Sea Shepherd Conservation Society. “It just sends chills up and down my spine when I think that we might have accomplished what most people would say was truly impossible – finding a large mammal that exists on this earth that is totally unknown to science.”Scientists are now using genetic sampling to confirm what the scientists found is really a new kind of beaked whale.The discovery of a new species of beaked whale proves how much mystery there is left to discover in the oceans that our captains, crews, and research partners fight to defend,” said Peter Hammarstedt, Director of Campaigns for Sea Shepherd. 1442

Saudi Arabia has confirmed the death of missing Saudi journalist and Washington Post columnist Jamal Khashoggi in an announcement on Saudi state TV.The Saudis have set up a commission that will investigate Khashoggi's death and will have one month to release a report, according to state TV. The commission will consist of national security officials, the foreign ministry and the interior ministry.Discussions between Khashoggi and those who met him during arrival at the consulate in Istanbul led to an argument and physical altercation that led to his death, the state TV report said.A total of 18 Saudi nationals have now been detained for investigation, the Saudi Press Agency reported.In the announcement on Saudi State TV, it said a royal order has been issued to release Maj. Gen. Ahmed al-Asiri from his duty as the deputy of the intelligence services.Asiri was believed to be the chief architect of the war with Yemen. He was previously the Saudi-led coalition spokesman in the kingdom's war against Yemen's Houthi rebels.The two-star general's position as spokesman made him a household name and he was soon part of the Crown Prince's inner circle.According to several sources, he chose the team involved in Khashoggi's disappearance.In their announcement the Saudis expressed deep regret over Khashoggi's death and the "painful developments" in the case. They affirmed the "commitment of the authorities in the Kingdom to bring the facts to the attention of the public and to hold accountable all those involved," according to a CNN translation of the announcement.Khashoggi disappeared October 2 after going to the Saudi Arabian consulate in Istanbul to obtain paperwork to marry his Turkish fiancée, Hatice Cengiz.She raised the alarm to police just before 5 p.m. on October 2 -- three and a half hours after the journalist entered the consulate. At that time she was still waiting outside.Turkish officials now say they believe that 15 Saudi men who arrived in Istanbul on October 2 were connected to Khashoggi's death. At least some of them appear to have high-level connections in the Saudi government. 2127

SAN YSIDRO, Calif. (KGTV) - A disturbing new trend at the US-Mexico border has several federal agencies teaming up, as teenagers are being arrested trying to smuggle Fentanyl into the country."Narcotics smuggling is not a new thing," says Customs and Border Protection Director of Field Operations Anne Marcicich. "But this is."In 2017, agents at the border caught 84 teens trying to smuggle narcotics. But none of them had Fentanyl. Already in 2018, they've made 41 arrests, including 6 for the dangerous drug. That includes five in the past week.Customs and Border Patrol believes enhanced security and screening has led drug dealers and cartel to target teens. They strap packages of the drug to their stomach or backs and walk across the border.In many cases, the teens are US citizens who live with family in Mexico and cross the border every day to go to school."These juveniles, they're being recruited in schools, on public transportation, while they're waiting in line to cross the border, by their families, and also on social media," says Special Agent David Shaw, with Department of Homeland Security Investigations. "They're offered quick money and even electronics for continued success."Now, CBP, Homeland Security, the San Diego District Attorney's office and the US Attorney's office are teaming up to let kids know how dangerous the drug can be, and the impact an arrest can have on their lives."They're being told nothing will happen to them because they're juveniles," says District Attorney Lisa Weinreb. "Nothing could be further from the truth,"Weinreb says the DA will prosecute all kids caught smuggling Fentanyl. And while they may not go to prison, they will be put through the juvenile justice system, which can include any number of rehabilitative steps. The arrest will also stay on their record and keep them from jobs or military service.In addition to the legal dangers, the physical danger can be worse. Fentanyl is a highly potent narcotic. Just a small amount, about the same as 30 grains of sand, is enough to cause a fatal overdose if ingested. Federal agents that confiscate and handle the drugs have to wear protective clothing and masks to make sure they're not exposed.Maricich says the kids don't realize they're putting their lives, and the lives of others, at risk when they strap a bag to their body. The agencies have started adding Fentanyl into their presentations they give at high schools around San Diego. They've been to 61 schools since 2009, but early presentations focused on marijuana and methamphetamine. Now they'll focus on Fentanyl."The message is clear," says Weinreb. "These youth will be caught and prosecuted if they engage in dangerous activity." 2735

(KGTV) -- The San Diego County Sheriff’s Department is investigating after three people were stabbed in San Marcos Friday night.The department says the stabbing happened on the 300 block of Autumn Drive just before 9 p.m.All three victims were taken to the hospital with non-life threatening injuries, the department said.Although the details surrounding the incident remain unclear, authorities say the suspect is still outstanding. 460

  

SEATTLE (AP) — U.S. scientists said Friday they will investigate why an unusual number of gray whales are washing up dead on West Coast beaches.About 70 whales have been found dead so far this year on the coasts of California, Oregon, Washington and Alaska, the most since 2000. About five more have been discovered on British Columbia beaches. That's a very small fraction of the total number of whales believed to have died, because most simply sink and others wash up in such remote areas they're not recorded.NOAA Fisheries on Friday declared the die-off an "unusual mortality event," providing additional resources to respond to the deaths and triggering the investigation."Many of the whales have been skinny and malnourished, and that suggests they may not have gotten enough to eat during their last feeding season in the Arctic," agency spokesman Michael Milstein told reporters during a conference call.The eastern North Pacific gray whales were removed from the endangered species list in 1994, after recovering from the whaling era.The population has grown significantly in the last decade and is now estimated at 27,000 — the highest since surveys began in 1967. That has raised questions about whether their population has reached the limit of what the environment can sustain. Another theory suggests that the loss of Arctic sea ice due to global warming is a culprit.The whales spend their summers feeding in the Arctic before migrating 10,000 miles (16,000 km) to winter off Mexico. Though they eat all along their route, they are typically thinning by the time they return north along the West Coast each spring.They eat many things, but especially amphipods, tiny shrimp-like creatures that live in sediment on the ocean floor in the Arctic. For many years, researchers noted that fewer calves tended to be born following years when the ice in the Chukchi Sea, north of the Bering Strait between Alaska and Russia, was late to melt. The whales had less time to feast because they couldn't access the feeding area, and thus had less blubber to sustain them on their next migration.Last year, though, the Artic was unusually warm. The whales weren't blocked from the feeding area, and yet are still struggling this year. That has scientists wondering if the loss of sea ice has led to a loss of algae that feed the amphipods. Surveys show the amphipod beds moving farther north, said Sue Moore, a biological oceanographer at the University of Washington."The sea ice has been changing very quickly over the last decade or so," she said. "The whales may have to shift to other prey, such as krill or other things they eat."In an average year, about 35 whales wash up in the U.S.In 2000, more than 100 did, prompting NOAA to declare an "unusual mortality event" then as well. The resulting investigation failed to identify a cause. The die-off followed strong changes in ocean conditions in the mid-1990s, suggesting that warmer water patterns affected the availability of prey, but scientists were often unable to perform necropsies, Moore said."It's sometimes very difficult to get to these whales in a timely fashion," she said. "You can't always get the kind of samples you would need for diagnostic reasons."Since then, researchers have built up an improved network of volunteers and have better educated the public to help report and respond to whale deaths, said Deborah Fauquier, veterinary medical officer at NOAA's Office of Protected Resources. This time around, scientists have been able to perform necropsies on 20 of the whales, she said.John Calambokidis, a research biologist with the Cascadia Research Collective, noted that as the whales search farther afield for food, they've entered areas where they're not normally seen so often, including San Francisco Bay and Puget Sound. That puts them at higher risk of being struck by ships or entangled in fishing gear.Four of the 10 gray whales found dead near San Francisco this year were struck by ships, and a number of shipping companies have slowed their vessels in the area to avoid collisions. 4086
