New York, April 13 (IANS) Photo-sharing service Snapchat is launching a new location-based product that will allow businesses see whether people go to stores after seeing advertisements. "With the new ad product, 'Snap to Store', marketers will be able to use the tool to measure whether their ad campaigns on the Snapchat app actually drive users to specific locations, like stores, restaurants and movie theaters," The Wall Street Journal reported on Thursday. The company has been testing its new product since last year with a handful of marketers, including Paramount Pictures and 7-Eleven. In terms of privacy, Snapchat says it only uses location data when people open the app and aggregates data from at least 1,000 Snapchat users into categories like gyms or restaurants, not specific venues. The company is also launching a dashboard that calculates incremental visitors as well as demographic information like age, gender and region. "Access to Snap to Store is available free to advertisers that reach a certain spending threshold with Snapchat, though the company declined to specify what that spending threshold is," the report added.

​Toronto, April 12 (IANS) Researchers have identified 26 new genes linked to intellectual disability which is characterised by significant limitations in learning.

More than one in 100 children worldwide is affected by intellectual disability. Frequently, intellectual disability also accompanies symptoms of autism spectrum disorders, and many genes have been found to be shared by the two illnesses.

The study, published online in the journal Molecular Psychiatry, could eventually lead to personalised treatments for affected individuals, and also add to our growing knowledge of brain development and functioning. 

"Knowing the genes involved is a big step forward, but understanding how they function is also crucial before we can start planning treatments or even cures," said team leader John Vincent from the Centre for Addiction and Mental Health in Toronto, Canada.

The study, which was jointly led with Muhammad Ayub of Queen's University in Canada, involved 192 families from Pakistan and Iran with more than one affected family member. 

Intellectual disability is frequently caused by recessive genes, meaning that an affected child gets a defective copy of the gene from each parent.

The families in the study all had a history of marriage among relatives, which occurs quite commonly in communities in South Asia, the Middle East and Africa. 

Studying families with this background, and multiple affected individuals, can enable researchers to identify disease genes that would otherwise remain hidden.

The research team pinpointed mutations related to intellectual disability in half of these 192 families. 

The identification of 26 new genes adds to 11 new genes that the team had previously linked to intellectual disability.

One immediate implication of the study is to prevent future cases of intellectual disability, the researchers note. 

Unaffected family members and relatives could be genetically screened to see if they carry these mutations. 

While 26 genes may seem a substantial number, there are likely hundreds of genes that, when defective, may lead to intellectual disability, the researchers pointed out. 

"The strategy we have used speeds up the process of identifying disease genes and of enabling diagnostic labs to deliver more accurate information for clinicians and families," Vincent said.

​London, April 12 (IANS) In a first, scientists have developed a drug activated by light which has therapeutic applications for the treatment of pain.

The new "photo-drug" -- JF-NP-26 -- is a molecule that can be specifically activated at any wished moment (that is, with a high spatiotemporal resolution) with light, the researchers said.

"This is the first light-activated drug designed for the treatment of pain in vivo with animal models," said Francisco Ciruela, Professor at the University of Barcelona. 

JF-NP-26 is activated when receiving light -- using an optical fibre -- of a suitable wave length and with an exact precision on the target tissue (brain, skin, articulations, etc).

The drug does not show toxic or unwanted effects even if the dose is high in short-length studies on animals.

The discovery, published in the journal eLife, will overcome the problems faced with the uses and effects of current drugs such as slow and inexact distribution of the drug, lack of spatiotemporal traits in the organism and difficulties in the dose adjustments, the researchers said.

JF-NP-26's lightening includes a treatment on the molecule that releases the active molecule (raseglurant) that blocks the metabotropic glutamate type 5 (mGlu5) receptor, found in lots of neuronal functions such as the spread of neuronal pain. 

Blocking this receptor allows preventing the pain from spreading into the brain. This can be produced both due to the outlying neurons and the central nervous system (brain) and create, in both cases, an analgesic effect as a result.

"The molecule created by the action of light, the raseglurant, does not belong to any group of drugs from the classic anti-pain list of drugs: non-steroidal anti-inflammatory drugs or NSAID (paracetamol, ibuprofen, etc.) and opioids (morphine, phentanyl)," Ciruela said.
