The cornea has no blood vessels. That’s weird. But it’s a good thing, or we would be looking through a network of threadlike strands all the time. According to EurekAlert, scientists at Scheppens Eye Institute decided to find out how the cornea stays clear. They found that it is heavily stocked with a special protein, VEGFR-3, that halts the normal progression of angiogenesis (blood vessel growth) that occurs in all other tissues of the body except cartilage.If this were the only thing allowing us to see clearly, it would be amazing enough, but it’s just the tip of the eyeball.

I was the only cadet and the only female on a Russian cruise ship where only the captain spoke English well.”Luckily, she eventually met another South African woman on board to whom she could relate.“Today I love my job and can imagine myself still doing this at the age of 65,” she said.Climbing the ranksThe group’s journey from cadet to master pilot was a lengthy one, involving many assessments and exams.The women were part of Transnet’s one-year maritime programme and did practical at-sea training on shipping lines such as Safmarine and the Unicorn.Training at sea was followed by an oral exam. Once they passed this, they became junior deck officers who auto-piloted vessels and managed safety equipment.The next step was becoming tug masters and then, after another year’s course, junior pilots.Becoming junior pilots enabled the trio to move up the ranks and through different grades until they reached their open-licence milestone.
Bournemouth held off a plucky Cardiff City to open the new Premier League campaign with a 2-0 home win thanks to goals from Ryan Fraser and Callum Wilson. Fraser’s close-range finish midway through the first half and Wilson’s stoppage-time effort proved the difference as Eddie Howe’s men ended a run of three opening weekend defeats.Wilson, scorer of eight league goals last term, had an earlier chance to put the result beyond doubt before half-time, but his spot-kick was well saved by Neil Etheridge, the goalkeeper becoming the first player to save a penalty on his Premier League debut since Allan McGregor for Hull City in August 2013.

Lilian’s son who is top of the Bundesliga with Borussia Monchengladbach Brazil, beware! Messi and Argentina out for revenge after Copa controversy Best player in MLS? Zlatan wasn’t even the best player in LA! It was to prove the only real joy for last season’s Championship runners-up, though, as a more competitive performance after half-time went unrewarded.Cardiff’s low-key off-season spending has prompted widespread predictions of an immediate return to the Championship and their deficiencies were evident across a one-sided first 45 minutes.Dominant in possession, Bournemouth turned their superiority into a deserved opener in the 24th minute as Fraser timed his run well to sweep home Wilson’s intelligent cut-back.Wilson should have opened his own account just beyond the half-hour mark, but, having been felled in a tangle with Bruno Ecuele Manga, the striker failed to beat Philippines international Etheridge, who turned the low attempt around his left post.The visitors were far livelier after the interval and, spared by David Brooks’ poor header at one end, almost scrambled in an equaliser with 25 minutes remaining, only for Asmir Begovic to deny Sean Morrison on the line.Bournemouth eventually reasserted a sense of stability and the second goal came in the 91st minute when Simon Francis bustled his way to the byline and found Wilson for a cool low finish into the bottom far corner. Our opening goal of the new @premierleague season…#BOUCAR // 1-0 pic.twitter.com/1EWrq4qdvE— AFC Bournemouth (@afcbournemouth) August 11, 2018What does it mean: New men key for CardiffMaintaining the status quo will not be enough for Cardiff to stay up this season. Though they fought bravely after half-time, the Bluebirds’ struggle to find a midfield foothold will have greater consequences against better sides. New arrivals Victor Camarasa and Harry Arter – ruled ineligible against his parent club – must be used sooner rather than later.Pat on the back: Fantastic FraserHis goal was just one fine moment in a match full of them for Fraser. The 24-year-old was a constant threat on the flank and would have had an assist to his credit had Brooks headed in a smart cross early in the second half.Boot up the backside: Bamba bamboozledNeil Warnock can perhaps view this loss as an insight as to what will not work in the Premier League. Chief among the findings should be that Sol Bamba is not suited to midfield. Asked to patrol the space in front of defence, the natural centre-back was found out for a lack of mobility and offered little on the ball.What’s next?Cardiff head back to Wales for the visit of Newcastle United next Saturday, while Bournemouth’s first trip of the season sees them visit West Ham. read more

Image Courtesy: Pixabay under CC0 Creative Commons license Following last week’s cyber attack, COSCO Shipping Lines informed that its network applications in the Americas have been totally recovered.“All communication channels including telephone, email, and electronic data exchange have been restored. There has been a further increase in our service response. We are working at full stretch to process all the service requests received previously, and the service response is expected to be back on track within this week. “Global networks of COSCO Shipping Lines are safe and stable, and our global business operations are steady and orderly,” the company said in an update.Initially, it was reported that the customer service platform at COSCO’s terminal at the Port of Long Beach was targeted by hackers. Nevertheless, the company later said that the network breakdown affected offices across the American continent.The network failures affected areas included the United States, Canada, Panama, Argentina, Brazil, Peru, Chile and Uruguay. However, the company’s ships were not affected and continued operating as normal.Commenting on the cyber attack, Naval Dome CEO Itai Sela said that the incident was very worrying.“While COSCO shut down its connections as a precautionary measure, we have to emphasize that ships are not islands, they are not self-contained units. This is a mistaken belief. Shore- and ship-operations are cyber-connected,” he said.“If shore-based and ship-based IT systems are linked, it could open a gateway to the COSCO ships, leaving them highly susceptible to an attack. Vessels do not need to be attacked directly but an attack can arrive via the company’s shore-based IT systems and very easily penetrate the ships’ critical OT systems.Although COSCO has been quick to respond to this hack, the virus may have been dormant for some time, so I would not be surprised if other systems – shore- and ship-based systems – have been breached.This kind of attack could spread through the entire fleet and its consequences might be devastating, and certainly costly, especially in terms of insurance. We strongly recommend to whoever discovered the attack, to thoroughly verify the breach has been contained and has not infected any ships in the COSCO fleet.This cyber-attack, like the Maersk attacks last year, will no doubt send shockwaves throughout the industry and encourage board members to take immediate, effective protection. Regulators need to implement workable rules and guidelines to help this vitally important global industry defend itself properly.”
