The band had humble beginnings as a garage band‚ managed by the father of the Wilson brothers‚ and their early work is notable for their gorgeous vocal harmonies and a California-inspired surf rock sound. Brian Wilson is often seen as being the visionary of the band. He is responsible for their unique soundscape‚ introducing elements The post Top 10 Beach Boys Songs appeared first on ClassicRockHistory.com.

New Giant Anaconda Species Discovered While Filming With Will Smith‚ Lab-Grown Testicles May Be Capable Of Producing Sperm‚ And Much More This Week

This week a tiny star only slightly bigger than Earth is the smallest ever discovered‚ a battery breakthrough could see electric cars travel 1‚000 kilometers on one charge‚ and a 40‚000-year-old glue suggests neanderthals were actually pretty smart. Finally‚ we question if math was discovered or invented.Subscribe to the IFLScience newsletter for all the biggest science news delivered straight to your inbox every Wednesday and Saturday. New Giant Anaconda Species Discovered While Filming With Will Smith In AmazonThe Amazon rainforest hosts the largest and heaviest (although not longest) snake species on Earth: the green anaconda. However‚ what was thought to be a single species covering a vast area has now been revealed as two‚ with a little help from Will Smith and an accompanying documentary crew. Read the full story hereSmallest Star Ever Discovered And It's Only A Tiny Bit Bigger Than EarthAstronomers have reported an incredible stellar discovery. Actually‚ they've reported two incredible discoveries: they have found the smallest star ever and it orbits its companion with the smallest known period for binary stars at just 20.5 minutes. Read the full story hereFirst-Ever Lab-Grown Testicles May Be Capable Of Producing SpermFor the first time ever‚ researchers have succeeded in growing a pair of testicles in the laboratory. Created from immature testicular cells taken from newborn mice‚ the cultured cojones quickly developed structures resembling those seen in natural knackers and may even be capable of sperm production. Read the full story hereBreakthrough Could Make Electric Cars Go 1‚000 Kilometers On One ChargeOne of the concerns in the transition from petrol-based to electric vehicles (EVs) is range. How far can you go on a single charge? Researchers believe that they have a formulation that expands on traditional design massively. They claim they can push the average range of EVs beyond 1‚000 kilometers (600 miles). The secret is silicon.

Made of a mix of bitumen and ocher‚ the multi-compound glue resembles that employed by early Homo sapiens in Africa‚ indicating that our ancient cousins may have had a similar level of cognition to our own ancestors.

So‚ which is it? Is math invented‚ with all those theorems and concepts so rigorously proved throughout millennia just a byproduct of human perception; or is it discovered‚ prompting the notion of some factual‚ real “six” out there in the cosmos somewhere? It’s a trickier question than you might think. Read the full story here More content:Have you seen our free e-magazine‚ CURIOUS? Issue 19 February 2024 is out now.

Sharks Can Have Bellybuttons – And Other Facts About Their Incredible Diversity

The first thing that pops into most people’s minds when they think of sharks is of big dumb fish with pointy teeth that are to be greatly feared. But as someone who spends their days studying these creatures‚ I know just how wrong that image is. For one thing‚ the diversity of sharks is astounding. The differences between species can even make it seem like some of these animals are barely related.My new research‚ carried out with colleagues in the UK and South Africa‚ shows that significant differences can even exist between male and female members of the same species. Our study of South African great white sharks revealed that females don’t always make the switch from eating fish as youngsters to eating seals and other marine mammals when they’re older. Instead‚ our findings suggest that some females may specialise on fish prey and use different habitats to males.How on Earth did we find this out? We conducted a type of chemical study known as stable isotope analysis on small pieces of muscle that we collected from free-swimming white sharks while on board a cage diving ecotourism boat. This gave us information on what the sharks had been eating and which habitats they had been using for a roughly two-year period – the first time that this analysis has been used on samples from live South African sharks.What do the results mean? If the females are spending more time in coastal areas than males‚ they may be more likely to be caught in in-shore fisheries and bather safety nets‚ as well as being exposed to more pollutants. This issue is already affecting South Africa’s white shark population. So better understanding the diversity of shark behaviour could help us improve conservation efforts.So many sharks.Image credit: cbpix/Shutterstock.comDifferences in the way the sexes use resources is called sexual segregation‚ and is fairly common in sharks. The reasons behind sexual segregation can be complex‚ sometimes involving different temperature or nutritional requirements or the need for females to give birth in special nursery habitats.Rough courtship and mating is likely one of the reasons why females grow to larger sizes than males (to be fair‚ males don’t have hands to hold on with‚ so they use their mouths). Female small spotted catsharks have been documented avoiding sexual harassment‚ keeping away from any romantic (or bitey) encounters with males by hiding out in shallow water caves in the daytime.Differences between the sexes is just one example of the incredible variety to be found among the sharks. Things get even more diverse when you look at different species. The sizes of the more than 400 species‚ for example‚ range from a 20-centimetre dwarf lantern shark to an 18-metre whale shark.They also come in a surprising variety of shapes‚ including the flat and ray-like angel shark and the rounded and eel-like frilled shark. Accordingly‚ their teeth come in a wonderful variety of forms too‚ from crushing plates used to crunch crabs in smoothhound sharks‚ to circular blade-like teeth that give cookiecutter sharks their name.All shapes and sizes.Image credit: Alex Rush/Shutterstock.comSharks have a variety of reproductive types too. Some lay eggs (that also come in a bunch of different shapes and sizes depending on the species). Some develop eggs that hatch inside them‚ producing pups that then develop in the uterus and are born later.Others give birth similarly to mammals‚ with a placenta and umbilical chord. The umbilical cord attaches between the pectoral fins and‚ when the pups are born‚ they’re left with an umbilical scar‚ effectively a bellybutton‚ which is visible for a few weeks until it heals up completely. A few shark species have also been found to have “virgin births”‚ reproducing without a sexual partner.Individual sharks have recently been shown to be just that: individual. In the last few years‚ the study of shark social interactions and personalities has come to the forefront of shark science. Researchers have found that lemon sharks show a preference for hanging out with familiar individuals. However‚ just like humans‚ some sharks are more sociable than others. Port Jackson sharks seem to have best friends that they like to spend time with year after year‚ and several shark species have been found to to be made up of individuals with different behavioural types‚ or personalities.You can even tell individual sharks apart based on their appearance. NASA developed the algorithm that is now used to identify individual whale sharks by their spot patterns (it was originally used to map stars). Each whale shark has a unique pattern that can be identified like a fingerprint‚ and software is now used to catalogue photographs of individuals to help us monitor their numbers and movement patterns. Several other sharks and rays are now identified by various pattern features. White sharks can be identified by the notches on their dorsal fins‚ as well as other distinguishing features.Georgia French‚ PhD Researcher of White Sharks‚ University of SussexThis article is republished from The Conversation under a Creative Commons license.
