The porch piracy problems were not all what they seemed.The idea was glorious: To get revenge on thieves swiping packages off doorsteps, ex-NASA engineer Mark Rober built parcels with a pound of glitter and fart spray that burst out when the lid was lifted. He also put phones in the package to record thieves' reactions and to capture their location.The video Rober released of five "glitter bombs" in action was the perfect antidote for anyone who'd ever arrived home to find only a doormat where a delivery should have been. They showed giant glitter messes and complaints about the stench (one thief even said he was worried about how his girlfriend would react to his smelly, sparkling car).But now, Rober is apologizing for footage of two of the glitter attacks, which he admits is "misleading."Rober explained that he'd asked his friends -- and friends of friends -- to try out his invention, even offering to pay those who could recover their packages.What Rober didn't know, he said, is that some people called on their own buddies to pretend to be robbers, then sent the sham reaction videos to Rober, who passed them off on social media -- unwittingly -- as authentic.Rober took to Twitter on Thursday to let his audience know about the mishap."From the footage I received from the phones which intentionally only record at specific times, this wasn't obvious to me," 1392

Three tiny balls of fur huddle together for warmth inside a cardboard box. The baby cheetahs are just a few weeks old, but they've had a traumatic start to life.A smuggler was attempting to spirit the cubs out of Somaliland, a breakaway state from Somalia, when he was caught red-handed by the authorities.The cubs, who will soon be taken to a safehouse, are the lucky ones. Some 300 young cheetahs are trafficked out of Somaliland every year -- around the same number as the entire population of adult and adolescent cheetahs in unprotected areas in the Horn of Africa, according to the Cheetah Conservation Fund (CCF).The trend is of "epidemic proportions," according to CCF, an organization devoted to saving cheetahs in the wild. At the current rates of trafficking, the cheetah population in the region could soon be wiped out."If you do the math, the math kind of shows that it's only going to be a matter of a couple of years [before] we are not going to have any cheetahs," said Laurie Marker, an American conservation biologist biologist and founder of CCF.Somaliland is the main transit route for cheetah-trafficking in the Horn of Africa. The animals are smuggled across Somaliland's porous border, then stowed away in cramped crates or cardboard boxes on boats and sent across the Gulf of Aden towards their final destination: the Arabian Peninsula.Status symbols for the richThere are less than 7,500 cheetahs left in the wild, according to CCF. Another 1,000 cheetahs are being held captive in private hands in Gulf countries, CCF estimated, where many are bought and sold in illegal online sales.While many of these states -- including the United Arab Emirates and Saudi Arabia -- ban the private ownership and sale of wild animals, enforcement is lax.The overwhelming majority of these cheetahs end up in Gulf Arab mansions, where Africa's most endangered big cats are flaunted as status symbols of the ultra-rich and paraded around in social media posts, according to CCF and trafficking specialists.In one such post, a video shows a "pet" cheetah watching a National Geographic show and becoming visibly agitated when it sees one of its own on the screen. "She's fixated on her family," reads the caption. Other posts show cheetahs laying on luxury cars, being shoved into pools, getting force-fed ice cream and lollipops, and being taunted by a group of men. One cheetah is seen getting declawed; another is dying on camera.For cheetahs, a life in confinement can be deadly, if the journey doesn't kill them first. Many of the smuggled cubs arrive in the Gulf with mangled and broken legs after a rough journey. Three out of four cheetahs die during the trip, according to Marker.As the world's fastest land mammal, cheetahs need space to run and a special diet. Most Gulf owners do not know how to care for the cats, and the majority of captive cheetahs die within a year or two, experts told CNN."Those people who have cheetahs as a pet are causing the species to go extinct," said Marker.Veterinarians in Gulf countries confirm this grim picture. They spoke to CNN on condition of anonymity because of the sensitivity of the issue."(Cheetahs) do terribly in captivity," said one vet, who has treated dozens of pet cheetahs over the past five years. Many of those he cared for did not survive.The vet said he has seen cheetahs suffer from metabolic and digestive disorders because people don't know what to feed them. He's also come across cheetahs with stress-related diseases and obesity due to confinement.Captivity is "a dead-end for cheetahs," another vet said. The big cat is a delicate species, especially susceptible to feline and infectious diseases, the vet said.In a statement to CNN, the UAE's Ministry of Climate Change and Environment denied there were cheetahs in the country's private houses and said that any cheetahs in the country were in "licensed facilities." The ministry also said it routinely tracks online advertisements for the sale of endangered species, removing 800 such sites so far.But CNN has seen a number of Emirati social media posts featuring pet cheetahs in recent weeks, and veterinarians told CNN they've treated dozens of cheetahs in private captivity, though they said numbers have gone down over the last several years. One vet credited the rescues in Somaliland, tighter controls at the borders in one emirate, and more rigorous e-commerce policing for the drop.Cheetahs for saleA CCF study last year documented 1,367 cheetahs for sale on social media platforms 4538

  

The rigors and challenges of spaceflight are remarkably similar to the physical stress cancer patients experiment during chemotherapy and other treatments, according to researchers.For that reason, the researchers suggest that the countermeasures program used by astronauts before, during and after spaceflight to maintain their health could be developed and applied for cancer patients to help them recover after treatment.The details were published in a commentary written by researchers from Memorial Sloan Kettering Cancer Center and NASA on Thursday in the journal 582

  

The Russian lawyer who attended a 2016 meeting at Trump Tower with members of the Trump campaign was charged by federal prosecutors in New York with obstruction of justice in a money-laundering case, according to an indictment unsealed Tuesday that highlighted her ties to the Russian government.Natalya Veselnitskaya, who gained prominence as a result of a meeting with Donald Trump Jr. and other members of the Trump campaign after he had been promised damaging intelligence on Democratic presidential candidate Hillary Clinton, was indicted by the Manhattan US Attorney's office.As that case proceeded, Veselnitskaya, a member of the defense team in that matter, allegedly gave a false declaration to the federal court in New York about the Russian government's investigative findings in that case, concealing from the court that she "had participated in drafting those supposed independent investigative findings in secret cooperation with a senior Russian prosecutor," according to the indictment.Veselnitskaya is not in the US and it's unlikely that she'll ever see court or be taken into custody unless she leaves Russia. She told CNN Tuesday that she would "defend her professional honor" in the case and declined to comment further about the matter, saying she just learned of the news.Emails released by Trump Jr. show that he agreed to the meeting after being told the "crown prosecutor of Russia" wanted to give the Trump campaign incriminating information about Clinton. Instead, Trump Jr. later said, Veselnitskaya focused on the repeal of the Magnitsky Act, a 2012 law that sanctions Russians accused of violating human rights.Veselnitskaya has said in interviews that she has a working relationship with Russian Prosecutor General Yuri Chaika and that they exchanged information during her lobbying efforts against the Magnitsky Act. She has denied that she has ever worked for the Russian government, and a Kremlin spokesman has said the notion was "absurd."It's unclear if there was any response from the Trump team to the request from Veselnitskaya concerning the Magnitsky Act. The Trump administration has not moved to roll back the Russian sanctions, and, in fact, new sanctions against Russia have been enacted.Special counsel Robert Mueller is investigating the Trump Tower meeting as part of his probe into Russian interference in the 2016 election. The special counsel's office declined to comment on whether it contributed to the Veselnitskaya investigation or referred it to the US Attorney's office. The indictment of Veselnitskaya appears to stem directly from the New York case concerning the Cyprus-based investment firm Prevezon Holdings Ltd. and its Russian owner, Denis Katsyv.Veselnitskaya attended proceedings in the US for the case, including a hearing in Manhattan on the same day of the June 2016 Trump Tower meeting.This story is breaking and will be updated. 2912
