Dolphins Cooperate by Talking It Out

by Elizabeth Preston in Inkfish



How do you know when animals are working together? Just because two animals got something done jointly doesn't mean they cooperated. They might have succeeded by dumb luck, or trial and error. Scientists who study animal minds, though, would really like to know when cooperation happens on purpose—and how animal partners manage to communicate with each other.

Studies in capuchin monkeys and chimpanzees hinted that the primates coordinated their actions by glancing at each other. (But this ........ Read more »

Canine Science is Better than Common Sense

by CAPB in Companion Animal Psychology Blog

We need canine science because common sense can lead us astray.Recently I wrote about why science matters to our dogs and cats, based on findings from Dr. Paige Jarreau’s research that suggests science blogs (like this one) may contribute to readers having a better knowledge of science.I thought of this again recently because a comment I often see from readers – on any kind of science story on the internet – is "don’t we know this already? Isn’t it just common sense?"I understand the c........ Read more »

Video Tip of the Week: MyGene2, connecting families with rare conditions with each other

by Mary in OpenHelix

Last week’s tip encouraged people to think about how their DNA may be used by various stakeholders. This could be researchers, physicians, pharmaceutical companies, and so on. But one thing it didn’t really cover–now that I think of it–was connecting with other families who may share variations that impact the health of someone in their […]... Read more »

Immune To Evolution

by Mark Lasbury in As Many Exceptions As Rules

Recent studies show that plant immune reactions include responses that are adaptive. Even more amazing, these responses include the recruitment of parasitic wasps to combat some herbivorous invaders. In addition, several plant chemicals that prime the immune responses have been identified, leading to a sort of immune memory. Plants do all this without a classical immune system. Once again, plants show us that in many ways, they are more complex than mammals.... Read more »

Weird stuff found in recreational drugs: Alcohol edition

by Rosin Cerate in Rosin Cerate

Today's post is the first in a series I'm going to write about extra ingredients found in illicit recreational drugs. One of the major issues with street drugs is their manufacture and distribution is often poorly regulated. This means they can accidentally become contaminated with all sorts of toxic substances during production. Additionally, a wide range of chemical compounds, some of them harmful, may be intentionally added to dilute a drug (like a bar watering down their drinks to make more ........ Read more »

Simple Jury Persuasion: “This is really about morality” 

by Doug Keene in The Jury Room

Here’s a research finding that some might call a “silver bullet” for litigation advocacy. We are always looking for nuggets of wisdom in research findings and this is one we think makes a lot of sense for use in court. These researchers wanted to see if people could “be induced to view their own attitudes […]

Cultural evolution in killer whales

by gdw in FictionalFieldwork

Auka watches mother and the other adults hunt. They are black-and-white ghosts flitting through the waters of their chilly world. Their prey is fast, agile. Coordination is key. Which is why the young ones have to stay behind. There is no place for playfulness during the hunt. But Auka doesn’t feel playful. She ignores the […]... Read more »

You laugh differently with friends than you do with strangers (and listeners can tell the difference)

by BPS Research Digest in BPS Research Digest

By guest blogger Lucy FoulkesThe amount and type of laughter between two people can potentially tell us much more than that they are sharing a joke. For example, friends laugh more than strangers, and shared laughter can be an indicator of sexual interest between a couple. But as onlookers, how well can we use the sound of laughter to make these kinds of inferences? A new study in PNAS is the first to investigate this and it turns out, regardless of our culture or where we live, we are pretty go........ Read more »

10,000 hours debunked again? In elite sport, amount of practice does not explain who performs best

by BPS Research Digest in BPS Research Digest

In elite sport, what distinguishes the best from the also rans? A new meta-analysis in Perspectives on Psychological Science looks at all the relevant data to see whether the most important factor is an athlete's amount of accumulated "deliberate practice" – that is, practice that's designed, through feedback and other methods, to improve performance. In fact, the new analysis shows that differences in amount of practice do not explain performance levels among elite athletes. At sub-........ Read more »

Stressed medial students and Lactobacillus casei strain Shirota

Mobilizing mitochondria may be key to regenerating damaged neurons

by Dr. Jekyll in Lunatic Laboratories

Mitochondria, sure it's the powerhouse of the cell, but maybe it can be much more that. At least that's what it looks like thanks to researchers at the National Institute of Neurological Disorders and Stroke who have discovered that boosting the transport of mitochondria along neuronal axons enhances the ability of mouse nerve cells to repair themselves after injury.

Cytopathogenesis of ZIKV: IFTM and viral entry/Hofbauer cells and the placenta

by thelonevirologist in Virology Tidbits

Zika Virus (ZIKV) is an emerging member of the Flaviviridae that in the past months spread to over 30 countries in the Americas alone that has been associated with the emergence of microcephaly, a condition associated with abnormal brain development, in Brazil and elsewhere.
Recent studies confirmed the presence of ZIKV in the amniotic fluid as well in the brain and CNS of neonates, suggesting that ZIKV can infect embryonal and foetal tissue by crossing the placental barrier. In addition, ZIKV ........ Read more »

Yes, the scientific findings reported by Sandra Strunz and colleagues [1] have said as much.Sorry to be so sarcastic about them but coming from a place where the words 'the bleedin' obvious' are commonly used, I couldn't believe that in 2016 anyone would genuinely believe otherwise.

Burying beetles are unusual among insects in that they provide parental care and are often monogamous. When burying beetle pairs find a small dead bird or rodent, they pluck it bald, coat it in antibacterial and antifungal body secretions, and dig a hole around it.
