On the last day of every month SuperForester Julius presents a monthly recap of the most amazing happenings in the world of science, technology and computing. Julius is currently in his last year of High school and plans on enrolling the Applied Physics bachelor this September.
The mysterious click of the sperm whale
Chances are that you’ve never seen a sperm whale before, at least, not in real life. Sometimes they show up on the television when they get stranded and disrupt entire towns. The sperm whale is one of the biggest species on Earth, a male can grow up to 20,5 meters (67 ft.) in length. This huge creature does something that has been bugging scientists for a while because they were unable to explain it (scientists generally need an explanation for everything). A sperm whale is able to produce incredibly loud clicks, they can reach an intensity of 230 deci-Bells while a loud gunshot (probably the loudest sound humans can produce) only reaches 160 dB. The deci-Bell scale is pretty vague if you don’t know the maths that go beyond it, so I’ll save you the hassle: 230 dB is about 10000000 times louder then 160 dB.
The question was: why do sperm whales do this?
Scientists got the answer from fisherman that were rather annoyed with the whale since it stole and ate their newly caught fish. On video recorded with underwater cameras the scientists saw that the whale produced it’s famous click when it was about to start dining/stealing. Just a matter of minutes later other whales joined and they had one big dinner party. The conclusion was that the whales did this in order to communicate, to say: “Yooo there’s free dinner here!”
The Ida fossil
The Ida fossil is probably the science news of the last month. Ida is the nickname of a fossil of the primate Darwinius masillae, a species that was walking the Earth a long, long, loooong while before we did.

This is her claw (wait, why am I applying a gender to it? I guess because her name is Ida… nevermind) and when this picture made the news it was reported that ‘they’ – being archeologists – found the missing link in our evolution. As a matter of fact the fossil was already pretty long in human hands, it was a private collection though so not a single scientist was able to analyze it. And the claim that the unprivatized fossil would be the missing link in our evolution was directly criticized by archeologists worldwide, saying Ida would be “more of an aunt”. Something which is perfectly demonstrated in this family tree.
Nevertheless it’s fun to know something about the history of your auntie, right?
Radical new approach to cancer
A few days ago I read something about a new treatment of cancer designed by mathematical oncologist (that’s a mathematician treating cancer, interesting combo by the way) Robert Gatenby. His treatment is radically different then the one applied today. He says that we shouldn’t want entire tumors to disappear when using chemotherapy. When this kind of treatment is used over time cells can and will build resistance for such a therapy and the tumor starts growing again. Gatenby’s suggestion is that we should lower the dosis so that a few cells will stay alive.
It turns out that non-resistant cells replicate much quicker then resistant cells, this is because resistant cells have to pour loads of energy into their resistance and thus replicate slower. This causes non-resistant cells to dominate in untreated tumors. Gatenby’s treatment would make sure that resistant cells won’t start occurring in large numbers and this would make the tumor manageable.
In an interview with Wired: Science Gatenby says that further research in better methods of treatment is an absolute necessity but that this could work for now. Of course there are major downsides to chemotherapy treatment which is another obstacle for the ‘new method’. At least there’s a lot of thinking going on concerning the problem of cancer, and the fact that it’s giving of it’s fruits is rad.
That rounds it up for May’s Most Amazing Science. Of course, not everything could have been covered. But if you feel like I’ve missed out on something huge feel free to share your scientific news of last month in the comments section. And if you feel the urge to share your thoughts about anything that got covered the comments section is opened too! Have an awesome Sunday!
