Two New Theropod Dinosaurs From China

by Brian Switek in Dinosaur Tracking

Paleontologists are discovering dinosaur species at a dizzying pace. These days it seems that a new species is announced almost every other week. Many of these new dinosaurs are being found in China, and two different teams of scientists have recently described a pair of unique species from two locations within the country. As described [...]... Read more »

Social Cognition in a Non-Social Reptile? Gaze-Following in Red-Footed Tortoises

by Jason Goldman in The Thoughtful Animal

Have you ever been at a party with lots of people chatting away, when for some unexplainable reason you felt compelled to turn and look at the front door of your friend's house...and just as you were looking, someone was just coming in from outside and closing the door? You couldn't have heard the door open since there was so much noise already inside - more likely you noticed that other people were looking at the front door. All of this probably happened without any explicit intention or focu........ Read more »

Does background music aid or impair reading comprehension?

by Psychology 379 bloggers in Cognition & the Arts

Everyone knows someone who likes to listen to some music while they work. Maybe it’s one of your kids, listening to the radio while they try to slog through their homework. Maybe it’s an uncle, playing his favorite record as he reads a book. Or maybe, god forbid, it’s a college senior browsing his iTunes as he desperately writes a last-minute blog post for his psychology seminar. Either way, they’re not alone – it’s a widely held popular belief that listening ........ Read more »

EGFR promote lung tumorigenesis by activating miRNA via the Ras/ERK/Myc pathway

Money CAN buy happiness…well, sort of.

by Scicurious in Neurotic Physiology

Who’d have thought we’d have gotten all this way in science and never studied whether money can buy happiness? Well, in fact, this HAS been studied, but the results have almost always been inconclusive. This probably has a lot to do with how it’s being studied, what ranges of monetary income you’re talking about, and [...]... Read more »

Mystery In Alaska

by Journal Watch Online in Journal Watch Online

The alarming case of the cross-billed chickadees – and crows, nuthatches and woodpeckers — began at two birdfeeders. In 1998, Alaskan biologists got reports of chickadees with grossly elongated beaks snacking at feeders in two widely separated parts of the state. Soon, birds with similar deformities began showing up across Alaska and nearby regions. Now, […] Read More »... Read more »

What do Cheese and H5N1 Have in Common?

by Sara Klink in Promega Connections

Earlier this year, the state of Wisconsin considered adding Lactococcus lactis as the state microbe. Wisconsin is known as America’s Dairyland, and L. lactis is part of the cheese-making process. While its run to become the state microbe was ultimately unsuccessful, I wanted to learn more about the L. lactis bacterium. A quick search through PubMed yielded an intriguing paper by Lei et al., and it had nothing to do with converting milk to cheese. ... Read more »

Shades of Gray: Gray literature, peer-review, and the struggle for data in fisheries management

by Southern Fried Scientist in Southern Fried Science

The dissemination of science follows the conventional route of rigorous peer-review followed by publication in an accredited scientific journal. This process has been the standard foundation from which the general public can trust that the science is, at the very least, valid and honest. Of course this system is not without its flaws. Scientific papers of questionable authority, [...]... Read more »

Free Prepackaged Meal Can Help Promote Weight Loss and Maintenance

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Losing weight and keeping it off, for most people, means reducing their caloric intake and maintaing a calorie-reduced diet for as long as they plan to keep the weight off (a rare few can depend exclusively on exercise alone to lose and keep weight off - most of us can’t).
This means, they will either have [...]... Read more »

Neither me nor thee: the fish in the mirror

by Zen Faulkes in NeuroDojo

If you want to get a Siamese fighting fish (Betta splendans) like this, show it another fish...

...or its own reflection.

Famously, very few animals understand reflections as representing themselves. There are veritable reams of papers written about the “mirror test” and how much it suggests about animal self-awareness, and therefore, animal consciousness.

Whether you agree with great apes or dolphins showing self-recognition in the mirror test, pretty much everyone agrees that fishes do........ Read more »

One of my new favorite things: paleovirology

by Jonathan Eisen in The Tree of Life

Just a quick post here about a paper that came out about a month or so ago: PLoS Biology: Genomic Fossils Calibrate the Long-Term Evolution of Hepadnaviruses

This paper, by Clément Gilbert, Cédric Feschotte is quite cool.  In it they describe their work on "Paleovirology" where they look for viruses than have "endogenized" by inserting into the genome of some host species.  This endogenization is important in particular when the endogenous form becomes inactive and thus, i........

The Lonely Hearts Club

by Shaheen Lakhan in Brain Blogger

Loneliness is a complex set of emotions that encompasses feelings of social isolation, unfilled intimate needs, and heightened feelings of vulnerability. Though transient for some people, chronic loneliness can take a physical and psychological toll on individuals, leading to increased morbidity and mortality. Specifically, new research indicates that loneliness raises blood pressure – a silent [...]... Read more »

by Erin Campbell in HighMag Blog

Cell biologists make amazing discoveries using cells grown flat on culture dishes, yet the cells in an organism grow and function in three dimensions. Some cell biologists use clever tricks to understand how cells function in three dimensions by using cells cultured in gels, and they find out very valuable information. Throughout biology there are many cases of oriented cell division, during which a cell orients the mitotic spindle on a specific axis. These cell divisions can occur throughout........ Read more »

The Study of Optical Illusions Prior to 1960 - With Illustrations

by John Wayland in The Darwin Tribune

Humans have been aware of optical illusions for a very long time. Indeed, recently, the study of illusions has provided psychology with many, many illusions. Colman (2006) states that broadly speaking, illusions fall into the following categories:Ambiguous figures, associative illusions, illusory contours, impossible figures, movement illusions, perspective illusions, space-time illusions, stereoscopic illusions, and visual aftereffects.Baldwin IllusionMany illusions actually were developed befo........

Corporate Social Responsibility

by Jan Husdal in

How far does corporate social responsibility go? While corporate social responsibility looks good on paper, how far are companies willing to not just talk the talk, but also walk the walk? For example, what should a company do if the authorities in a foreign country are clearing away residential areas (and removing residents without any compensation) to make room for industrial development that may allow said company to expand its offshored manufacturing facilities? Interfere? Do nothing? Milton........ Read more »
