12:08 PM | Somatic mutation: does it cut both ways?
I've written journal articles as well as blogposts here at MT, about the known and potential importance of somatic mutation (SoMu) as a cause of disease.  I referred to this in our post on 'precision' medicine yesterday, saying I'd write about it today.  So here goes, an attempt to show why SoMu may be an important causal phenomenon, one I called 'Cryptic causation' in a paper a few years ago in Trends in Genetics.SoMu's are DNA changes that occur in dividing cells after the egg […]

10:53 AM | Rodent Sticky Trap Snags a Rat and a Lizard
I have heard of the use of sticky traps for studying lizards, though a colleague told me they seem to be of uncertain safety for anoles, as his recapture records were almost nonexistent. We finally gave up on the “bio-warfare” of feline-infantry to a recent rodent invader to the house, and had to put this […]

9:00 AM | CO2 stimulation of photosynthesis in Liquidambar styraciflua is not sustained during a 12-year field experiment
Atmospheric carbon dioxide levels have increased by ~ 25% over the last 50 years. While more carbon dioxide can initially stimulate plant photosynthesis, in a new study published in AoB PLANTS, Warren et al. found that long-term (12 years) exposure of sweetgum trees to elevated carbon dioxide resulted in no stimulation of photosynthesis. The loss […]

8:00 AM | The Different Types Of Tears
Tears might be a welcome relief from eye irritants or an unwelcome proof of an emotion we'd rather keep to ourselves. Different types of tears not only serve different purposes, but they're made up of different substances. Basal tears are constantly keeping our eyes wet and protected, while emotional tears contain high levels of stress hormones that have been found to provide physical relief from pain as well as a decrease in testosterone in men. And reflex tears, which happen in response to […]

Smell: Fact or Fiction Blind people gain an enhanced sense of smell to compensate for the lost sense, right? Right? Wrong. It turns out that it’s a total myth. Avery Gilbert, a scent psychologist, takes a critical look at some of the widely circulated myths surrounding our less understood sense of smell. By: World Science Festival.

The Great Pheromone Debate Pheromones are chemicals secreted by an organism that trigger a social response in members of the same species. Hive insects such as bees and ants rely on these chemical signals to direct the group to a goal or raise an alarm. Since their discovery, scientists have tried to deduce what sort of behaviors human pheromones induce to varying results. But is it possible to paint a pheromone on something to get an immediate social reaction? Scent psychologist Avery Gilbert […]

9:43 PM | Maybe the UTRGV mascot should be the zombie, because the debate won’t die
Just when thought we had finished with the whole Vaqueros controversy, it’s back in the news. Texas lawmaker Terry Canales has made good on his threat.... er, promise... to introduce legislation that would almost certainly get rid of the “Vaquero” as mascot. The bill, from my point of view, is... problematic. It reads:The university shall include on the ballot:the “Broncs”;the “Ocelots”; andany other options the university chooses, including nicknames […]

9:32 PM | The secret for a longer life? Kill your unfit cells
If you had the choice, would you like to live until you’re 130 years old? New research in fruit flies shows that manipulating a single gene can extend their lifespan up to 60%, suggesting that living well into your hundreds might become a reality in the foreseeable future.Dying of old age is a strange thing. Why does our health decline just because we’re old? Although the answer might at first seem obvious or simple, it really isn’t. There are countless theories of ageing, a […]

8:52 PM | 92 new species of colorful squat lobsters
A few days ago, Enrique Macpherson & Aymee Robainas-Barcia published a paper in the journal Zootaxa in which they describe 92 new and colorful species of squat lobsters (Galatheidae). The study that lays behind this new paper included more than 9000 specimens collected in the Indian and Pacific Oceans. Squat lobsters are often amazingly colorful, and […]
