4:02 AM | Ocean Things to Be Thankful For: Megalodon is Dead, but We Still Have Sharks (and Whales)
This time of year, it’s appropriate to think of things to be thankful for.  This being an ocean-focused blog, I’d like to share something ocean-related that I’m thankful for, and hopefully spread a little Ocean Optimism in the process.  What I’m thankful for is that Carcharocles megalodon is extinct.  This may not seem like cause […]

1:55 AM | It’s Good to Laugh
Alleged intellectual Christina Hoff Summers (I know, I know, it’s bad form to give away the punchline of a joke so early) recently had this to say: Dear liberals, When you side with today’s 3rd wave intersectional feminism, you are siding with the intellectual equivalent of creationism. As a liberal feminist whose day job actually […]

6:45 PM | Centipede’s genes reveal how life evolved on our planet
Centipedes, those many-legged creatures that startle us in our homes and gardens, have been genetically sequenced for the first time. An international team of over 100 scientists today reveals how this humble arthropod’s DNA gave them new insight into how life developed on our planet. Centipedes are members of the arthropods, a group with numerous … Continue reading →

6:10 PM | People ate mammoth; Dogs got reindeer
Biogeologists have shown how Gravettian people shared their food 30,000 years ago. Around 30,000 years ago Predmosti was inhabited by people of the pan-European Gravettian culture, who used the bones of more than 1000 mammoths to build their settlement and to ivory sculptures. Did prehistoric people collect this precious raw material from carcasses — easy … Continue reading →

6:00 PM | Why lizards have bird breath: Iguanas evolved one-way lungs surprisingly like those of birds
Biologists long assumed that one-way air flow was a special adaptation in birds driven by the intense energy demands of flight. But now scientists have shown that bird-like breathing also developed in green iguanas – reptiles not known for high-capacity aerobic fitness. The finding bolsters the case that unidirectional bird-like flow evolved long before the … Continue reading →

5:49 PM | Dizzying heights: Prehistoric farming on the ‘roof of the world’
Archaeological findings pose questions about genetic resistance in humans to altitude sickness and genetic response in crop plants to flowering times and ultraviolet radiation tolerance. Archaeological discoveries from the ‘roof of the world’ on the Tibetan Plateau indicate that from 3,600 years ago, crop growing and the raising of livestock was taking place year-round at … Continue reading →

5:39 PM | Darwin 2.0: New theory on speciation, diversity
It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent study shows that speciation occurred much later than these dramatic geographical changes. Researchers have found that time and a species’ … Continue reading →

8:47 PM | Blind Scottish Centipede Reveals How Venomous Carnivores Evolved
Usually blind sages revealing the secrets of the universe are Asian. Scotland doesn't get enough respect that way but a centipede is defying the stereotype. Arthropods are one of Earth's real success stories, with more species than any other animal phylum. Genome sequencing has been skewed towards the more popular insects, and even an arachnid and a crustacean, and now finally the myriapods (centipedes and millipedes) are emerging from the dark.read more

As a woman, it pains me to admins this: there’s good evidence that, in tests of spatial awareness, men typically outperform women. Yes, men really do tend be better navigators. But why?

4:05 PM | New Tool Use in a Bird
Under the right environmental conditions, and with a little innovation, great antshrikes prove they’re capable of cognitively flexibe tool use. Tool-use is a new behavior for this species – they’re using anvils to crack open the shells of invasive land snails.

1:08 PM | As A Bird - It's No Turkey
Mr. Carlson and Herb Tarlek had to deal with the aftermath of bombing Cincinnati with live turkeys. The line about turkeys being able to fly is one of the most famous in TV history. But he should have at least questioned whether they could fly, there are more than 50 species of flightless bird alive as we speak.In a famous 1978 episode of the TV sitcom, WKRP In Cincinnati, station manager Arthur Carlson releases turkeys from a helicopter to a waiting crowd below as part of a holiday publicity […]

8:40 AM | Four perspectives on human decision making
I have been rereading Gerd Gigerenzer’s collection of essays Rationality for Mortals: How People Cope with Uncertainty. It covers most of Gigerenzer’s typical turf – ecological rationality, heuristics that make us smart, understanding risk and so on. In the first essay, Gigerenzer provides four categories of approaches to analysing decision making – unbounded rationality, optimisation under constraints, […]

8:15 PM | After The Sun Incinerates Earth, Life Could Evolve On Titan
In about 4 billion years, our sun will become a red giant star, engulfing the inner planets and basking the outer planets in its ebbing heat. When the happens, according to a NASA scientist, Saturn's moon Titan, which resembles a frozen version of Earth billions of years ago, could evolve its own indigenous life. Read more...
