If you're interested in fish who are scary-looking, poisonous and chock-full of elaborate defense mechanisms, look no further than the stonefish, a genus of fish that populate coastal waters of the Indo-Pacific region.As if their deadly venom and spiny exteriors weren't enough, scientists at the University of Kansas have found that stonefish also have a hidden switchblade on their face that they can flick out whenever they feel like they're in danger.Scientists call the bony, blade-like protrusion a "lachrymal saber," because it is located on a bone under the fish's eyes. Also, "lachrymal saber" is just a really metal-sounding name.William Leo Smith, associate curator and associate professor of ecology & evolutionary biology at KU, first started to understand how the lachrymal saber worked 15 years ago, when he was dissecting a stonefish he kept as a pet.This is a game-changerHe tells CNN the mechanism isn't just a cool new discovery (although it's that, too). It also changes the scientific understandings and classifications of this particular type of fish."It opens up these ideas of ecological questions. Muscular systems, bone systems, nervous systems all came together to form this. What led to its evolution or use?In other words, he says, "Why do we see this accumulation of so many horrible things on one fish?"The lachrymal saber is housed inside the fish's head, and they use their cheek muscles to deploy it. Though some stonefish are venomous, the saber is not.It could be a sex thing, tooSmith says he and his fellow researchers have reason to believe the saber isn't just for warding off predators: It could be a sex thing, too."There is evidence pushing towards that," he says. "They may use this in battles with other members of their species, like ram horns. It may also be involved in courtship behaviors."Oh, and the sabers glow."It's fluorescent green," Smith says. Since stonefish rely on camouflage for both protection and hunting prey, Smith doesn't think the fluorescence has a defensive purpose like, say, warning off predators.There are 134 described species of stonefish, and by Smith's observation, all of them have some form of lachrymal saber.  2202

In a letter sent to 950 patients, University Hospitals Fertility Center blames human error for the loss of 4,000 eggs and embryos, twice the number initially reported.The letter says the Cleveland hospital is “heartbroken” to inform patients it is “unlikely” any of the eggs and embryos are viable.The letter says a remote alarm system on the storage tank containing the eggs and embryos, which was designed to alert a UH employee to temperature fluctuations, was turned off.It is unclear when the remote alarm was turned off, but an alert to an employee as the temperature inside the tank began to rise Saturday night was not sent or received, according to the letter.It is also unclear who turned off the alarm and how long the alarm was turned off.The lab was not staffed March 3, the night of the malfunction. There was also a history of malfunctions involving the storage tank.In the letter, UH said the storage tank in question “needed preventative maintenance.”For weeks prior to the malfunction on March 3, “we experienced difficulty with what is called the liquid nitrogen automatic fill” and were working with the manufacturer to correct the problem.“My clients’ lives and future aspirations were crushed and destroyed. Finding out how simple of a matter it would have been to prevent this tragedy shakes my faith in the medical profession to the core,” said Brian Taubman, an attorney representing patients affected by the malfunction, in a statement to Scripps station WEWS in Cleveland. “My clients trusted UH with their future family, never doubting that those lives were safeguarded and with the flip of a switch their lives and potential lives were changed forever,” said Taubman.The hospital also says it takes responsibility for the failures and apologized several times to the affected patients. The letter says, “Those failures should not have happened, we take responsibility for them – and we are so sorry that our failures caused such a devastating loss for you.”  2015

If you've texted with an iPhone user in the past few days, you've probably had a tough time reading their messages.That's because a bug with the latest version of the phone's operating system is causing problems with a single letter — the capital I.Over the weekend, users began reporting bugs when trying to type messages with a capital I. For some reason, the letter auto corrects to a capital A with an unknown character.  448

Humans haven’t been to the moon in decades, but when mankind returns, they’ll be welcomed with cellphone technology not currently available in some reaches of the US.Nokia announced this week a partnership with NASA to construct a 4G network on the moon. The network will assist NASA's Artemis program, which is intended to send people back to the moon by 2024.Nokia says that its 4G moon network will allow for NASA to operate rovers and stream high-definition video.“Reliable, resilient and high-capacity communications networks will be key to supporting sustainable human presence on the lunar surface. By building the first high performance wireless network solution on the moon, Nokia Bell Labs is once again planting the flag for pioneering innovation beyond the conventional limits,” said Marcus Weldon, Chief Technology Officer at Nokia.On Wednesday, NASA said it will “announce an exciting new discovery” about the moon next week. NASA said that returning humans to the moon could support allowing humans to reach Mars by the 2030s. 1049

If you are still out of work, chances are the bonus unemployment check has helped you out. The 0 weekly bonus passed by Congress earlier this year helped millions of Americans who lost their job due to the pandemic. OUT OF TIMEThe benefit is set to expire on July 31, however because of payment schedules, this week will be the final week of the benefit. Congress is not expected to pass a new round of relief by next week although they could offer back-pay should relief legislation eventually pass. WHY IT MIGHT NOT BE EXTENDEDDemocrats have called for extending the benefit or at the very least enhancing current unemployment payouts. Republicans, however, are more skeptical, with some believing the incentive is stopping Americans from returning to work or looking for new work. THIS WEEK IS CRUCIALNegotiations are well underway and this week will be full of developments. That's because Congress is back from their Fourth of July recess. Senator Mitch McConnell and Rep. Kevin McCarthy, both GOP leaders in Congress, met with President Donald Trump at the White House today. On Tuesday, Trump Chief of Staff Mark Meadows and Treasury Secretary Steve Mnuchin will attend meetings on Capitol Hill. President Trump is even rumored to potentially make an in-person appearance on Capitol Hill this week. Everything from expanding small business loans to another stimulus check is expected to be included in the negotiations. 1438
