Researchers say adding sweet smells to food could cut sugar intake and help tackle obesity.

Sensors that detect odours in the nose have been found in human taste cells on the tongue, scientists have discovered.

The finding suggests that interactions between our senses of smell and taste may begin on the tongue and not in the brain, as previously thought.

Until now, taste and smell were considered to be independent sensory systems – but Mehmet Hakan Ozdener, a cell biologist at the Monell Center, Philadelphia, was prompted to challenge this belief when his 12-year-old son asked him if snakes extend their tongues so they can smell.

The discovery could lead to the development of “odour-based taste modifiers”, Ozdener said, which could one day help deter people from consuming excess salt, sugar, and fat.

Is your favorite actor past his or her prime? Mathematicians have developed a way to find out Mathematicians delved into IMDb, the Internet database of all things related to movies and TV programs, in an effort to predict when actors’ careers have peaked or are on the decline. The researchers from Queen Mary University of London, who published their work Tuesday in the journal Nature Communications, discovered that actors’ most productive year, defined as the year they had the most roles, is toward the beginning of their career.

A study has discovered the same olfactory receptors that detect odors in our nose can be found in taste cells on the tongue . However, the implications of the discovery suggest fascinating future research directions for understanding how the smell of food can interact with taste signals on the tongue .

The findings suggest that interactions between the senses of smell and taste, the primary components of food flavor, may begin on the tongue and not in the In the study , published online ahead of print in Chemical Senses, Ozdener and colleagues used methods developed at Monell to maintain living

While many people equate flavour with taste, the distinctive flavour of most food and drink comes more from smell, the researchers say.

Taste, which detects sweet, salty, sour, bitter, and umami (savoury) molecules on the tongue, evolved as a gatekeeper to evaluate the nutrient value of what we put in our mouths.

Smell provides detailed information about the quality of food flavour, for example – are you eating banana, liquorice or cherry? The brain then combines input from all these senses to create a multi-modal sensation of flavour.

Ozdener and colleagues used genetic and biochemical methods to examine taste cells in culture (where they are grown under controlled conditions outside of the mouth). They found human taste cells contain many key molecules known to be present in sensors found in the nose.

DNA taken from 31,000-year-old human teeth reveals a new ethnic group that was living in 'extreme' conditions in Siberia during the last Ice Age

DNA taken from 31,000-year-old human teeth reveals a new ethnic group that was living in 'extreme' conditions in Siberia during the last Ice Age The breakthrough came when two children's milk teeth were found buried deep in a remote archaeological site in north eastern Siberia. It comes as part of a wider study which also discovered 10,000-year-old human remains in another site in Siberia. Scientists claim these people were related to those who became the first Native Americans and this is the first evidence of a close relation to the first human colonists of the continent found outside the US.

US-based researchers have reported odour sensors in the nose are also present in human taste cells found on the tongue . The findings suggest that

The researchers also used a method known as “calcium imaging”, and found the taste cells responded to odour molecules similar to the sensors found in the nose. This lead them to believe that scent and taste cells interact on the tongue.

Other experiments by the scientists found that a single taste cell can contain both taste and olfactory (scent) receptors, ”[this] provide us with exciting opportunities to study interactions between odour and taste stimuli on the tongue,” said Ozdener.

Nazis Killed Her Father. Then She Fell in Love With One..
1. Such appalling events Emilie Landecker was 19 when she went to work for Benckiser, a German company that made industrial cleaning products and also took pride in cleansing its staff of non-Aryan elements. It was 1941. Ms. Landecker was half Jewish and terrified of deportation. Her new boss, Albert Reimann Jr., was an early disciple of Adolf Hitler and described himself as an “unconditional follower” of Nazi race theory. Somehow, inexplicably, they fell in love. The story of Ms. Landecker, whose Jewish father was murdered by the Nazis, and Mr.
