Inhale and feel it with your heart
by Aurametrix team in Olfactics and Diagnostics
All you need is love. Or failing that chocolate.And not only because dark chocolate could lower the risk of heart disease, blood pressure and sugar levels. As Dr. Schieberle's team recently discovered that heart could sense and enjoy the sweet smell of chocolate too. When they put small odor-emitting molecules from chocolate on one side of a dish, cells actually moved towards the aroma.The heart, the lungs, the blood, the sperm and testis all have the abilities to recognize chemicals responsible........

Getting Science Right: Blacklist For Fake Journals
by Katja Keuchenius in United Academics
He saw respected journals getting hijacked, bogus articles being published quasi-professionally and so-called open access websites covered with “BUY NOW” buttons. So librarian Jeffrey Beall decided to do something about it. He created a black list of all the journals (343!) he thinks are questionable and put it on his website scholaryoa.com. In this interview he explains why.... Read more »

The Craptastic Conversations of the Black Rhinoceros
by Miss Behavior in The Scorpion and the Frog
What are you saying with your smells? Image by freedigitalphotos.net.Animals communicate in all kinds of ways: with vocalizations, body language, vibrations, and even odors. In fact, compared to most species, we are pathetic in our abilities to communicate with body odor. With just a whiff of eau de crotch, many animals can decipher that individual’s species, sex, age, health status, reproductive status, emotional state, and dietary history. Some species can go so far as to make out that indiv........ Read more »

Fill the tank, please. With bacteria!
I apologize if you've already heard about this, but the paper is really cool and I couldn't resist discussing it here.Escherichia coli, or E. coli for brevity, is a bacterium normally associated with "bad" things like food poisoning. Even though most strains are actually harmless, even the CDC has a page dedicated to E. coli outbreaks. Since it's part of our gut flora, the lower intestines in particular, it's usually not a good sign when E. coli is found in places like restaurants and cafeterias........ Read more »

Describing Dog Training: Weasel words or clear descriptions?
by CAPB in Companion Animal Psychology Blog
Dog training is an unlicensed profession. Sometimes it surprises people to learn there is a science to training, the origins of which can be traced back to Pavlov and Skinner. When studying how ordinary people train their dogs, scientists have to map between technical terms and everyday language. How do they do this?You’ve probably heard the phrase that “dogs do what works”, as explained by Jean Donaldson in her wonderful book The Culture Clash. What this means is, the behaviours tha........

Imperial research explains what is cracking up Africa

A powerful earthquake in China’s rural south-west, which measured 6.6 in magnitude, highlighted the importance of research to understand what is happening inside the Earth’s rocky and often violent interior.
Dr James Hammond, from the Department of Earth Science and Engineering at Imperial, has published research in the journal Geology about what is happening to a region below the Earth’s crust called the mantle. He is studying the mantle in a part of East Africa called the ........ Read more »

Venomous Plants – A Hairy Situation
by Mark Lasbury in As Many Exceptions As Rules
There are many thousands of poison plants, but not too many are venomous. The nettles and the dendrocnidaes have hollow spines that deliver neurotoxins when they stab you. Recent research has shown that nettle toxin is beneficial in liver regeneration. It stimulates cell proliferation and reduces apoptosis. In an opposite effect, the dendrocnidae toxin called moroidin is a mitotic spindle inhibitor. It may prove useful as an anticancer drug.... Read more »

Study Further:
Technically speaking, researchers have found that the compounds that stimulate the cannabinoid type-2 (CB2) receptor in white blood cells, particularly in macrophages, can reduce the severity of HIV-1 infection. CB2 is responsible for showing the effects of cannabis.
