  • Researchers have found a new drug that may eventually help to reduce alcohol addiction in adults who used to binge during their adolescent years.

A new drug found which can reduce Alcohol addiction in teenagers

“During our teen years, the brain is still in a relatively immature state. Binge drinking worsens this situation, as alcohol undermines the normal developmental processes that affect how our brain matures,” said lead author Jon Jacobsen, a Ph.D. student at the University of Adelaide, Australia.

“Therefore, when an adolescent who has been binge drinking becomes an adult, they’re often left with an immature brain, which assists in the development of alcohol dependence,” Jacobsen added.

For the study, published in the Journal Neuropharmacology, researchers observed that adolescent mice involved in binge drinking behavior developed an increased sensitivity to alcohol as adults and engaged in further binge drinking.

The researchers were able to prevent some of these detrimental behaviors observed in adulthood, by giving mice a drug that blocks a specific response from the immune system in the brain.

The drug is (+)-Naltrexone, known to block the immune receptor Toll-like receptor 4 (TLR4).

“This drug effectively switched off the impulse in mice to binge drink. The mice were given this drug still sought out alcohol, but their level of drinking was greatly reduced,” says senior author Professor Mark Hutchinson, Director of the ARC Centre of Excellence for Nanoscale BioPhotonics at the University of Adelaide.

“We’re excited by the finding that we can potentially block binge drinking in an adult after they have experienced such behavior during adolescence, by stopping the activation of the brain’s immune system. It’s the first time this has been shown and gives us hope that our work has implications for the eventual treatment of alcohol addiction in adults,” Hutchinson noted.(IANS)

Australia Proposes To Strengthen Regulations of Facebook, Google

The Australian Competition and Consumer Commission (ACCC) on Monday proposed measures to counter the dominant market positions of Google and Facebook and strengthen monitoring on their access to information, advertising and consumers personal data.

The regulatory body, which recommended 11 preliminary measures in the report, was directed to conduct a public inquiry into the impact of digital search engines, social media platforms and other digital content in 2017 by then treasurer and current Prime Minister Scott Morrison.

“Acting as an intermediary between consumers and news outlets, platforms are inherently influential in shaping consumers’ choices of digital journalism,” said the report cited by Efe news.

This influential position and filtration of news items could place the consumer in a so-called filter bubble, increasing the risk of consumers being exposed to unreliable news, according to the report.

“The algorithms operated by each of Google and Facebook, as well as other policies, determine which content is surfaced and displayed to consumers in news feed and search results,” it said.

“The ACCC considers that the strong market position of digital platforms like Google and Facebook justifies a greater level of regulatory oversight,” Chair Rod Sims said.

The commission called for the creation of a regulatory authority with powers to monitor these digital platforms and recommended establishing an automatic mechanism to take down content that violates copyright.

The ACCC said consumers should be informed about the manner in which these platforms collect and use their data to create personalized advertising.

This would include a reform of privacy laws to require the user’s express consent to data collection and “enable consumers to require erasure of their personal information where they have withdrawn their consent”.

ACCC said that it found that “competition may have been distorted in multiple sectors where consumer data is used”.

In 2017, Google registered 90 per cent of search traffic originating from Australian desktops and 98 per cent from mobile phones. (IANS)
