London, Feb 21 : N-Dubz singer Tulisa Contostavlos has taken to Twitter to praise a wrinkle-killing remedy based on snake venom, calling it "amazing."

The 24-year-old singer tweeted her love for Skin Chemist's Wrinkle Killer Snake Serum, a 135-pound potion that includes syn-ake - a neuro-peptide that mimics the effect of the Asian temple viper's venom, the Daily Mail reported.

Syn-ake, which has also been called `Botox in a bottle,' temporarily freezes wrinkles - preventing them from getting any deeper.

Washington, Feb 21 : Jessica Biel took to Twitter to gush about how well her husband Justin Timberlake performed at the Brit Awards on Wednesday.

"My huz just killed it on the Brits," Us magazine quoted her as tweeting.

The 32-year-old singer - fresh off his much-praised Grammys appearance on February 10 - treated the crowd at London's O2 Arena to the first-ever live version of his new song, `Mirrors,' the official second single from his upcoming album, `The 20/20 Experience.'

Washington, February 21 : Researchers from Gottingen and Bonn have shed light on why the chemical compound known as "methylene blue" is a potential candidate for treating Alzheimer's.

The compound is considered as a potential Alzheimer's drug because it prevents the harmful clumping of so-called tau proteins typically associated with this disease, but until now it was unknown why it had this effect.

According to scientists including Markus Zweckstetter and Eckhard Mandelkow, methylene blue inactivates molecular residues that promote the bonding of tau proteins.

Chennai, Feb 21 : Harbhajan Singh will become the 10th Indian to play 100 Tests when he takes the field in the first Test against Australia here Friday.

Agartala, Feb 21 : With thousands of people from either side of the border gathering at colourful functions to commemorate the "language martyrs", India and Bangladesh jointly organised the International Mother Language Day.

The day was first declared a special day for celebrating linguistic and cultural diversity by UNESCO in 1999. On Feb 21 each year, Bangladesh remembers the students who were killed when they demanded introduction of Bangla as state language while the country was still part of Pakistan, in 1952.

Washington, Feb 21 : A study combining genetic data with brain imaging has not only identified the APOE gene, tied to the development of Alzheimer's, but has uncovered its link with another gene, called BCHE.

The enzyme coded by the BCHE gene has previously been studied in post-mortem brain tissue and is known to be found in plaques (deposits), which cause Alzheimer's.

These findings, based on PET scans of 555 participants in the Alzheimer's Disease Neuroimaging Initiative, could open the way to more effective drugs for Alzheimer's or slow, reverse or even prevent the disease, the journal Molecular Psychiatry reports.
