A study led by researchers at Lund University in Sweden shows that ravens are as clever as chimpanzees, despite having much smaller brains, indicating that rather than the size of the brain, the neuronal density and the structure of the birds' brains play an important role in terms of their intelligence.

"Absolute brain size is not the whole story. We found that corvid birds performed as well as great apes, despite having much smaller brains", says Can Kabadayi, doctoral student in Cognitive Science.

Seven international tobacco control experts urged government regulators to avoid heavy-handed condemnation of e-cigarette use, in a study published online today in the journal Addiction.

The researchers noted that regulations of e-cigarettes are clearly needed, but that governments need to weigh growing evidence of the benefits e-cigarettes provide in helping some addicted cigarette smokers quit against the potential for harm if non-smokers take up vaping, the term commonly used to describe use of e-cigarettes.

URBANA, Ill. - Last summer, the Gulf of Mexico's "dead zone" spanned more than 6,400 square miles, more than three times the size it should have been, according to the Gulf Hypoxia Task Force. Nitrogen runoff from farms along the Mississippi River winds up in the Gulf, feeding algae but depriving other marine life of oxygen when the algae decomposes. The 12 states that border the Mississippi have been mandated to develop nutrient reduction strategies, but one especially effective strategy has not been adopted widely: bioreactors.

EAST LANSING, Mich. - Around the world, especially in developing nations, counterfeit medicines are a real problem. Until now, in many countries there hasn't been a standard protocol to conduct investigations and pursue prosecution.

New research, led by Michigan State University and featured in the current issue of the Journal of Forensic Science and Criminology, is providing the foundation to apply criminology theory to preventing the production and sale of fake and substandard medicines.

EUGENE, Ore. -- April 25, 2016 -- Open the box of that new smartphone. Oops, it feels differently from expectations based on what you'd seen. Embrace it or be disappointed? Your reaction is likely tied to your perception of the brand, says Aparna Sundar of the University of Oregon.

A brand viewed as exciting has wiggle room to introduce innovations that don't match consumers' expectations, said Sundar, a professor of marketing in the Lundquist College of Business. Not so for a brand seen as sincere, she said.

Researchers working in the field of synthetic biology use components that occur in nature and combine them in a new way. This is how bacteria acquire functions that they hadn't previously possessed. This offers great potential for biotechnology.

Bacteria respond to temperature and metabolic products

Johanna Roßmanith and her doctoral supervisor Prof Dr Franz Narberhaus from the Chair of Microbial Biology carried out a successful study where they controlled the type of proteins a bacterium would manufacture and its behaviour. This is how they have made a bacterium swim that hadn't previously had the ability to move. The researchers made that possible by combining various modules from the bacterium's RNA in a new way.
