Your Labor Day science roundup

Happy Labor Day, everyone! Whether you're relaxing or laboring away like we are, take a break and check out some of the latest in science news from around the Web:

- Grief may not be unique to humans; New Scientist reports that dolphins seem to have a complex reaction to the death of another dolphin, displaying behaviors suggestive of mourning in certain situations. Other research has shown that gorillas, chimps and elephants also may show some understanding of death.

- Here's a headline you don't see every day: "Cyborg Beetles’ Neural Implants Could Suck Power From Bugs’ Wing Beats," reports Discover Magazine. Let's take that apart: Researchers are looking to take living beetles and implant neural devices in them to control their flight. By harvesting power from their beating wings through small generators, you wouldn't even need batteries. This technology is still a work in progress, however.

- Speaking of powering things, a Nature Nanotechnology study shows the creation of the smallest electric motor ever devised, the BBC reports. The motor is made from a single molecule with a diameter of 1 billionth of a meter, smaller than the width of a human hair. An electric current can drive a single one of these tiny motors, the researchers demonstrate. This could be useful for targeted drug delivery and other areas of medicine and nanotechnology.

- If you feel nauseated riding in the back seat of an automobile, inside a rocky boat or strapped to a roller coaster car, there may be good news coming: NASA and the U.S. Navy are looking for better ways to treat motion sickness, Scientific American reports. About 30% of people are immune to motion sickness, but no one knows why others are more susceptible to feeling on the verge of vomiting in certain situations. One of the best ways of overcoming it is adaptation - that is, getting used to the motion that's giving you problems, experts say.

    People are always looking to find animals they consider as smart as they are

    Has it occurred to anyone that maybe animals arent so dumb,maybe we just arent as smart as we think we are?

    Been through many comments that touch upon a lot of interesting and relevant topics. Some with more negativity than the others.
    Adding my 2 cents;
    Someone mentioned 'culture' while discussing morality and sensitivity towards killing (animals or humans doesn't matter – does a pig enjoy getting bludgeoned any better than your father/mother/brother/sister?)
    I found that very interesting. In fact I think there is one perspective to this line of thought (cultures and their attitude towards killing). Again, I am trying to put a non-partisan view and definitely not taking a hit at any culture. As we have it, different cultures evolve differently primarily influenced by their environment.
    As someone else rightly said, God created animals and vegetation and the fittest can go eat what he wants. Man was created as an Omnivore. Which means eating meat is very much on his menu.
    Over time, Man's thinking evolved. He started reasoning, questioning and trying to understand life. As he evolved, in certain cultures(such as many vegetarian communities of India, etc), his sense of morals(right vs wrong) also evolved. His sense of empathy also evolved. It was more easy to relate to the suffering of an animal when compared to plants as we shared(largely) a common anatomy. Blood is what one saw in a pig and blood was it in a human. In some cultures Man decided to believe hurting animals is incorrect. He started relying more on vegetation(vegetables/greens/fruits). Soon Man discovered better means of agriculture and in some cultures was able to completely give up Meat/egg/etc. Of course vegetation is also life. Fortunately back then, people didn't take up extreme scientific experiments to calibrate plant 'pain' and plant 'suffering'. You had to eat something to survive. They decided to eat something that at least appeared to them as less violent.
    So what do we understand from this. The higher that a culture evolved, the more humane it became. The less violent it became. The more tolerant it became.
    Many cultures did not take this path of evolution. Does it make them wrong? Not at all.
    However, it is more likely for a meat eating culture to be making lesser fuss about killing animals. Let us be fair. Let no hypocrite make you believe he is a dog lover while he has beef/pork on his breakfast plate. As someone rightly said, if dog's intelligence and loyalty makes you love him, a pig can score better if given half the chance. Pigs are as smart as your 4 year old toddler.
    Taking it a bit further, it is also more likely for those who have little or no hassles killing animals to be that much more less worried harming humans as well. That is a fair linkage between certain cultures that are cruel to their animals also being cruel to mankind!

    To put things into perspective, let us take a example of a dad taking his daughter to pick up stuff for their lunch. let us say he wants his daughter to meet her food and also pack her food on her own.
    Scene -1
    Dad and daughter go to a farm, dad gets hold of a nice little lamb. Gives his daughter an axe and asks her to chop the lamb"s head off. He then teaches her how to cut the lamb in nice little pieces. Scraping out the brains(it is a delicacy in certain cultures) and then packing them all up in nice little bags to carry them back home and cook a tasty meal.

    Dad and daughter go to a vegetable farm, pick lovely red carrots, some potatoes and maybe some spinach if the girl likes them, put them in a nice little bag and ride back home to cook a tasty meal.

    If any of us have an issue with Scene-1 and we are meat eaters, we are nothing but hypocrites.

    If any of us see no difference in both scenes, we may be the spiritually most evolved beings of our times.

    All said and done, there is no wrong vs right in this world. The world is but the image you see through the prism you choose.

      Karma? Do you actually believe in such a thing?

      20,000 or so dead is karma for the actions done by a few people whom have no relations to those who died other than being the citizen of the same country. Karma or not, the fact you think people should die because some other people in that group did something you don't agree with? That's pretty sick if you ask me.

      In that case, by your logic, when will the karma for your country's sins come to visit you? Or by extent of the same logic, the sins of your ancestors and their countries.

    With all respect to the intelligence involved in the topic, it is regrettable to say that asking this to the mass idiots around is mega stupidity: Those who care least about dolphins will say 'No' and those who excessively care will jump around to say 'Yes'. End of the day, may be, its the dolphins who will have the final say on this, and for you to confirm that, the best way is to become a dolphin and nail it for yourself rather than bragging around. Now Get your popcorn and watch some soccer.

    The writer should do a bit more research on her topics before posting.
    It has been shown conclusively that elephants and higher primates have an understanding of death and morn loss even years after. Elephants will revisit sites and bones of dead familly members when repassing a territory and primates will hold and grieve for a dead friend or relative. Different but equally complex behavior has been shown in whales, dolphins and other mammals.

    These creatures are incredibly intelligent and just because we don't understand what they are saying dosen't mean they aren't capable of thought, emotion, and high intellect. And yes canines and felines (wild or domestic) mourn as well. It's arrogant to think it is only humans.

    September 5, 2011 at 4:47 pm |
    • ARJUN

      Eloquently and accurately put. Our conceitedness makes us assume that H. sapiens is the only species capable of "higher emotions"...which if you look around the world right now, seems to be painfully absent!

      September 5, 2011 at 6:14 pm |
    • ajk68

      That animals would have emotions is not that significant. If they possessed the ability for abstract reasoning, that would be quite different.

      i've seen deer grieving over other deer that were killed in the ditch.

      and our collie cried when grandpa sold the puppies. she used to cry for about a week or so...that was obvious by her eyes. not sure how long she grieved after that. crying was more obvious.

    Ummm they think this is news? We have often observed cats and dogs mourn deaths of loved ones (animal or human), and dolphins are smarter than them. They can become depressed and lethargic after a companion dies, and will stay near the corpse in mourning. And yes, they can sense when someone is dead or dying, just as when they know their prey is dead. Cats/dogs have saved their owners' lives by going for help during a medical emergency. There's a story about a dog who goes around a hospital and comforts everyone who is about to die. It can sense when someone is in poor condition and needs comforting.

      Yes but it's so fun to see the photo of the cute smiling fishes. Did your know when you beat a Dolphin senseless with a club they still smile? they LOVE it . They don't have clue. Only humans understand anything. (I'm have to say this as i'm under contract) Throw me a ball!!!!!

    Have you ever watched fish at a fish market? When it's time to capture one in the tank, the fish go wild. At least they're smart enough to know that something's up. Do they realize that, if captured, they will be bludgeoned to death? Or are they just afraid of the proximity of the net?

    September 5, 2011 at 3:04 pm |
    • Wzrd1

      Since they're prey in the natural environment, they're prey in that tank too. They sense the movement of the water, being compressed by the motion of the net and react to a potential threat.

      September 5, 2011 at 3:09 pm |

        Yes that's right. Stupid fish. Just a little dumb machine. Same with cows, chickens, and lab rats. God put them here on earth to use. Thank you God for that cheese burger. Thank you God for that medicine. Thanks God for the blessings we receive. You still there?

      First, they're bugs. Not even with enough brainpower for anything more than mate, eat, fly from danger. Second, they're studying them to learn from them, how EVIL! What next? Complain when virii and bacteria are studied too?
      Second, what in the hell are you talking about, dolphins being more advance than us? OK, what was the last thing a dolphin said to you? If they're so advanced, they obviously have developed some means to communicate with us! They should easily avoid those nets too!
      Foolish, ignorant idiot. Try LEARNING about life, rather than deriding science for trying to learn about it.

    A bigger problem is that the Japanese don't understand the immorality of killing dolphins, and whales for that matter. In fact the Japanese don't seem to understand the immorality of causing death or pain to any other living beings, including humans. I personally feel a more profound loss when I learn of the death of a dolphin than I do whenever I learn of the death of any Japanese.

      Which is ironic because we kill PIGS, cows, deers, and etc. Pigs are one of the most intelligent mammals, they have an intellect capacity they far exceeds the average 3-4 year old human child.

      Doc, do you eat? Do you eat meat? Cattle have a fair amount of intelligence, pigs a tremendous amount of intelligence, greater than that of dogs. Do you murder plants to eat too?

      September 5, 2011 at 3:08 pm |
    • lightyears

      Deeming killing another creature as immoral because of it's intelligence is a value of your own society or your own way of thinking (which is affected by your culture).

      Laws are made to protect humans, their rights, and the morals of a society, right? Such a law dealing with whales, doesn't fall into the first two categories, so analyzing it from the latter; Morals of a society are determined by the majority of that society. Japan (and other countries) don't really have that value of not killing an animal because it is intelligent. Trying to force your opinion on someone is cultural imperialism.

      If it is not affecting other countries to any significant negative degree, it's not affecting the human race, they are not endangered then they don't have to make any such law unless they want to. You can disagree with it, and protest against it, and you should if you feel strongly about it. Hopefully over time you can change that society's opinions to more closely match yours, but because one has no right to say they are above anyone else ("I'm right, you're wrong"), you really shouldn't try to shove your opinions down their throats. Only doing so brings forth negative reactions and feelings which not only hurt and hinder your own cause but indirectly affects others by the negative impressions and feelings you caused in the other people. In the worst case scenario, over time this can plant a seed for things even as bad as racism to develop, and if that seed grows to large or reaches someone in power, wars and such can come about that can affect a large number of humans. As another example, this has been done for ages over spreading ones religion with negative means (spreading religion in itself is not bad).

      Protest and try debate and change peoples feelings peacefully.

    "Do Dolphins understand death"? Well, not as humans would interprete the event I don't believe. From what I understand, for Dolphins, it has less to do with a spiritual transcendence to another plane of existence and more to do with a "Why am I in a freakin' tank being made to do stupid tricks just in order to eat while idiot tourists take pictures of me " sort of thing.

    Wow, a major error in this artice: The article says that researchers have made beetles into cyborgs. The "cyborg" neural implants have yet to be put into the beetles, and they did not control their flight at all – they only looked to see how much power they could get from the beetle's wings flapping (between 45 and 115 uW) using a phenomenon called piezoelectricity.
    Also, the phrase about the nanomotor being 1billionth of a meter, "smaller than a human hair", is comical – 1 billion of a meter (a nanometer) is WAY smaller than a human hair! Like 100000 times smaller than a human hair (which is usually ~ 1 ten-thousandth of a meter).

      Thank you for your comment. I made a clarification in the post.

      Hah, I was totally about to post about the human hair thing. Yeah, a hair is like ~90,000 nanometers across, on average. Still pretty cool though.

    This article was not well written. I was interested in the article in reference to dolphins and other mammals who may understand death and morn. Very little said. The article switches very quickly to a motor attached to a bug. I don't get it.

    • Uh wow

      Uh, did you click the link for the dolphin story? Might want to do that before you go calling people on how badly you think the story was written, considering it's on a different website and this is just a brief summary of the article.

    The research they are talking about is really not new. Many animals have a basic understanding of death. But that understanding is very basic. They know their companion,friend, or offspring is gone and they mourn until instinct pushes them forward. No one has proved that any animal has a concious understanding of death the way humans do. It's sad in many ways because if humans only understood death the way animals do then in many ways we would live happier lives but probably much shorter lives as well since we would think nothing of taking ridiculous risk. lol. But still humans are indeed unique for what ever reason you choose to belive. We have a concious state of mind and good or bad that is something no other Animal has as far as we know.

      Like humans understand death? LOL. Oh yes, and hat's why there are so many 'knowing' churches, and everybody killing each other over it. Think of it; people kill each other over the idea of death! : religion. And the knowing Hindus (no offense, it's all the same), believe if they mess up they are 'demoted' to an animal in the next life .Demoted? LOL You mean 'promoted' A zoo.

      You understanding of the animal psyche is very limited. Elephants have been know to return to the "grave" site of deceased family members years after they have died. They even pick up and handle the bones. While not inconclusive this does suggest that elephants have a deep understanding of death.

    For those of you complaining about using the beetles for power, please read the article more carefully. The power generated is used to power the control system and nothing else. That means they would not need to be handled multiple times to replace batteries. If you still have trouble with the "slavery" issue, that's fine. However we are not sucking energy from beetles to power our homes.

    How interesting that this article talks about dolphins mourning, and then goes on to talk about beetles being used to generate energy. Would we run the beetles until they die from exhaustion? It sounds terrible. Please don't do this, it's cruel.

    Another genius article. Let me tell you something Einstein, even cats completely understand death. Have you ever seen a cat mourn? The mope around and whine for days or weeks. And their behavior changes DRAMATICALLY. All yof a sudden they become FRIENDLY! think of it. They want comfort. Idiot articles.

      That's right. One of my cats was very close to my dog. They used to sleep together. When I had to put the dog down, the cat seemed very sad and was rubbing her head on the dog's bedding and making weird noises.

    yes all animals understand death. there are videos all over the internet where animals have had their other animal friends hit by a car and they try to help them. one dog even pulled his friend out of the road after it was hit 🙁 also dogs on "death row" know when they are about to be euthanized for no good reason but lazy owners who left them there because they think they are objects they can just throw away when they don't want to care for them anymore.

      That's why not everyone is fit to have a pet, the same way that not everyone should have a kid.

        thats why spaying and neutering animals is so important. but only people with some common sense understand this concept.

    I think it's the height of human arrogance to think that we are the only animals that understand death, or that grieve. How dare we presume such? Clearly, anyone who believes this kind of rubbish has never had much dealing with animals.

    • fofo

      To be fair, I guess the scientist job is to prove what most everyone already knows except the religious who claim that animals don't have soul and that God created them for the pure pleasure of human.

    Insects into slavery to produce power, hmmm. Dolphins no doubt very intelligent. Great nano work it met its target time deadline of 10 years. But insect slavery for power, just dont seem right. firsty
