Expanding Universe

by Brian Koberlein in Upon Reflection

Figure 1: Two models of Newton's universe. Newtonian gravity predicts that stars were packed together tightly in the beginning, and expanded out into space. Over time, the stars either would collapse back together or expand forever. (Source: John D. Norton)...... Read more »

Immunization for Addiction: the Cocaine Vaccine

by Evil Monkey in Neurotopia

Every so often this cocaine vaccine issue rears its head again. I saw it again just the other day. The problem is, of course, the tendency of the media (ain't it always the media) to say something like "OMG THIS IS TEH CURE FOR EVERYTHING!" in response to one small study. And who knows, the cocaine vaccine may indeed be the cure for everything, but Sci needs to see some big trials before she gets her hopes up. As it is, the studies I have seen provide some interesting clues, but also provide........ Read more »

I have a big beak and a small tongue: Hornbill feeding

by Zen Faulkes in NeuroDojo

In the movie Roxanne, Steve Martin’s Cyrano-esque character has a scene where he’s supposed to drink from a small fluted wine glass, but his character’s large schnoz makes it impossible. That’s sort of the task faced by several birds species with large, lengthy bills.

Feeding is no small task for birds. Keep in mind that birds have no hands to manipulate their food, and a bird’s bill is completely inflexible. Imagine trying to eat without moving your lips.

Hornbills (like Aceros cass........ Read more »

Birds of a feather are bred together: domesticated turkeys in prehistoric SW US

by Rachel in The Sage of Discovery: Exploring the world of food one ingredient at a time

Turkeys have long been an important foodstuff in many parts of the world. In the U.S., not only has our post-colonial society been fueled by this fowl; historically, turkey meat, feathers, and bones have provided important uses for pre-contact Native Americans. But where did these birds come from? By examining the remains of turkeys from [...]... Read more »

Jury still out on fizzy drinks and pancreatic cancer

by Cancer Research UK in Cancer Research UK - Science Update

This week, the headlines have made bold claims about a possible link between drinking too many fizzy drinks and an increased risk of pancreatic cancer.

Chocolate Milk: The Ideal Post-Exercise Drink?

by Travis Saunders, MSc in Obesity Panacea


For anyone who has spent any time around a gym or even around fervent gym goers, you have probably heard the adage that chocolate milk is the ideal drink of choice post exercise to aid in recovery. In fact, dairy companies have put out commercials advertising the purported athletic benefits of drinking chocolate milk post exercise. I must admit that I personally love a 500ml carton of chocolate milk after my workouts. But is there any evidence to support all the hype?


Now, before I go any fur........ Read more »

On “the real holes in climate science”

by Andy Russell in Our Clouded Hills

[This post is based a question I got in response to a previous post but thought it deserved a short post on its own as there's a few interesting points.]
There’s been a lot of bad press recently for climate science but a lot of has focused on very minor issues. For example, most of [...]... Read more »

Is the Evolution Debate Over?

by Johnny in Ecographica

A recent blog post at National Public Radio’s “Cosmos And Culture” by astrophysicist Adam Frank has raised my hackles. The post, titled “The Evolution Debate Is Over; It's Time To Move Forward,” argues that “it's time to put the prejudices that drag down discussion between science and the domains of human spiritual endeavor aside.”

Are We All Homeopaths Now?

by Neuroskeptic in Neuroskeptic

There are two main kinds of Complementary and Alternative Medicine (CAM) - the ones that involve actually doing stuff, and the ones that don't.Things like herbal medicine, chiropractic, and acupuncture could plausibly make someone better, as more than just a placebo, given what we know about physics and chemistry, because they involve physically acting on the body. I don't claim to know whether they do in fact work, but in theory, they could.Other CAM techniques, however, are just magic. Homeopa........ Read more »

Metformin: an anti-diabetic drug that is also anti-aging?

by ouroboros in Ouroboros: Research in the biology of aging

To the growing list of small-molecule drugs that have a measurable effect on lifespan or healthspan (e.g., resveratrol and rapamycin) we should add metformin, an anti-diabetic drug that has shown promise as a calorie restriction mimetic. Onken & Driscoll determined some of the genetic requirements for metformin’s anti-aging properties in the worm C. elegans:

Paroxetine (Paxil) Use Lowers Cancer Survival in Tamoxifen Users

by Margaret Polaneczky, MD in The Blog that Ate Manhattan

An important Canadian study has shown that the use of paroxetine (Paxil) in breast cancer patients taking tamoxifen is associated with an increased risk of death from breast cancer. These findings, which were published this week in the British Medical Journal, add to a growing body of evidence that certain (but not all) SSRI antidepressants neutralize tamoxifen's beneficial effects in treating breast cancer by interfering with it's metabolism.First, a few things about the study -The study was d........

What's the buzz?: Synthetic marijuana, K2, Spice, JWH-018

by David J Kroll in Terra Sigillata

My field of natural products pharmacology was founded by indigenous cultures who recognized that plants and fungi contain compounds that produce altered states of consciousness, leading to their most common use in religious ceremonies. While we may most often associate these naturally-occurring drugs with hallucinogens, the arguably most common natural product in use today is marijuana or Cannabis sativa. Indigenous to India and China, Cannabis has been the subject of increasing decriminalizati........ Read more »
