Kiefer, eight, said shark eggs were hard to find as they were hidden in seaweed and rocks"They look like mermaid purses, that's what they're called," he said. "It's great fun because I like finding all the stuff."
Erin Cowham, the trust's senior education officer, said children taking part in the paid and ticketed event were "citizen scientists" and the sharks around the island were small, so there was no need to be afraid.She said the the sharks and rays laid eggs out at sea and, once they hatched, the cases washed up on the beach."The national Shark Trust gather data on all the distribution and maps where all the sharks and rays are in the British Isles," she said."We add the data we collect to that so they can build a picture of where they all are".

Falmouth Basket Shark aims to raise sea pollution awareness
A creative project aiming to raise awareness of marine pollution is set to see a 20ft (6.1m) model of a basking shark - made from sustainable materials - taken to a Cornish Basket Shark has been made out of items including willow, pallet wood and bamboo in a project led by Falmouth University lecturer Duncan model has been on display in Falmouth's National Maritime Museum during the half-term break and is set to travel down to Gyllyngvase Beach on Sunday to mark World Ocean Cameron said the plan was for the shark to stay at the beach during summer so people could fill it up with plastic found on the sand, before it is taken back to the university in the autumn. He added the year-long project had been set up to highlight the dangers of plastic and marine pollution with a "carbon-neutral but high-impact" project involved other groups including Plastic Free Mylor, the National Maritime Museum, the Shark Trust and Surfers Against Sewage, who worked alongside Mr Cameron and students to develop the shark. He added he was delighted with how the project had gone and been able to let "voices be heard" on an important subject."It's a creative project, but underneath it all there's this larger conversation about plastic in the sea," Mr Cameron said."With all projects, you have an idea and plan and hope to bring people along with you and there have been hundreds of voices in making this shark."

Nasa rover spots strange Martian rock that looks like ‘chocolate cake'
Nasa 's Curiosity rover has spotted a strange rock formation on Mars that looks like a multilayered chocolate cake. The rover team faced a technical challenge to find a safe area on the Red Planet to deploy the space vehicle's APXS spectrometer and MAHLI camera instruments. They eventually managed to place the APXS equipment on top of a prominent rock to study its target Martian area, including layered rocks named 'Hale Telescope' after the famous astronomical landmark in San Diego, California. The rover imaged and conducted analyses of another target a little further from the Hale Telescope area called 'Fan Palm'. In all, the Curiosity rover completed a drive of some 23 meters in preparation for the study plan lasting three Martian days. Curiosity now has its instruments as well as the APXS spectrometer set on the 'cakey target', planetary scientist Scott Van Bommel from Washington University said in a Nasa blog post. 'Perhaps it was because of Easter last weekend, perhaps I needed an early lunch,' Dr VanBommel commented, 'whatever the cause, I could not shake the visual parallels between the rocks in our workspace as captured in this blog's image and a many-layered cake such as a Prinzregententorte.' The weathering patterns on the rock formation make it look like a 'layered cake that little fingers have picked the icing off,' researchers say. The spacecraft has undergone a new AI software upgrade, giving it greater autonomy to choose its next target, Nasa noted. An upgraded version of the Curiosity's AEGIS instrument would enable the rover to autonomously determine the target and analyse it with its chemical analysis equipment. The rover's encounter with the strange rock formation occurred just days after it was captured driving across the Red Planet for the first time from orbit. An image taken by the Mars Reconnaissance Orbiter showed Curiosity as a dark speck at the front of a trail of rover tracks about 320m long. Since its landing at the Martian Gale Crater in August 2012, Curiosity has uncovered many details about the Red Planet's ancient habitability, helping find if it ever had the conditions to support microbial life. Its mobile science lab analyses rocks, soil and the Martian atmosphere, looking for chemical signatures of life. It has made several landmark discoveries, including evidence of ancient riverbeds, organic molecules, and past habitable environments. The rover has also helped determine the current Martian climate and radiation levels which could help future astronauts prepare for exploration.

Bizarre ‘impossible colours' your eyes CAN'T see – days after scientists discover mystery new hue ‘Olo' we've all missed
THE world is full of colour - but there's more than what meets the human eye. There is an untold number of "impossible colours" that humans can't see or even imagine. 4 4 Earlier this week, researchers at the University of California, Berkeley, and the University of Washington claimed to have discovered a new hidden colour called "Olo". They found a way to hijack the retina and artificially expand the natural human capacity for colour. Using a prototype known as "Oz", researchers flashed a laser light with a single monochromatic colour (usually observed as green) at participants eyes. This is when participants began seeing a new colour - one they were unable to recreate when given red, green and blue light to mix. But given enough white to desaturate it, participants and researchers discovered "Olo", a light bluey-green colour. There is no definitive number of "impossible" colours on Earth - but it's not zero. And it's unclear where they might occur. Although some animals can see them. This is because different species have different numbers and types of colour receptors in their eyes, allowing them to see a broader or narrower range of the electromagnetic spectrum. You have eyes of a hawk if you can find the missing bunny in this colourful Easter-themed brainteaser in 30 seconds The mantis shrimp is king of the colour wheel here, detecting ten times more colour than a human. It is believed to see more colours than any other animal on the planet. Why can't humans see "impossible Human eyes are trichromatic - meaning there are only three types of cones that respond to colour. The three colours they respond to are primary: red, green, and blue. These primary colours are the foundation of all the colours we see. What are considered "impossible" colours are shades that exist outside our trichromatic vision. Other animals, however, have more cones in their eyes that respond to colour. Like the mantis shrimp, which has a whopping 16 colour-receptive cones behind its eyes. There are three main categories of these mysterious shades: forbidden, chimerical, and imaginary colours. 4 Forbidden Forbidden colours are those that are not possible to see directly because of the way our cone cells in the retina work. For example, red-green or blue-yellow. Although some people report that they can see these forbidden colours, according to Anne-Laure, founder of Ness Labs and a PhD researcher at King's College London. You can use the templates above to see whether you are one of the lucky few. Simply make your eyes cross so that both "+" symbols are on top of each other. Chimerical Chimerical colours are another type of "impossible" colour, like stygian blue, for example. These are colours that can only be perceived through brain tricks like optical illusions or afterimages. Imaginary colours are ones that cannot be physically produced or perceived by the human eye. They exist in mathematical colour spaces but not in the 'real world'.
