This is especially important for identifying biopsy sites of nonmelanoma skin cancer (NMSC) patients as they typically have to wait up to three months between a biopsy confirming their condition and treatment.

However, the commercially available tattoo pigments inks can cause discomfort and inflammation.

The new ink developed by researchers led by Kai Chen University of Southern California is time-limited. Under ambient lighting, the nanoparticles are invisible, which would avoid unwanted markings in a patient’s skin, and is a safer, more patient-friendly option.

Testing in mice showed that tattoos created with these nanoparticles did not cause inflammation and lasted for three months.

The UK government on Thursday announced that it will move India from the red to the amber list on Sunday, in the country's latest update to the 'Red-Amber-Green' traffic light ratings for arrivals into England amid the Covid-19 pandemic.

This means the visit visas for the UK from India are open, in addition to other long-term visas that have remained open. But travellers from India arriving in England can complete a 10-day quarantine at home or in the place they are staying (not mandatorily quarantine in a managed hotel).

Pakistan has failed miserably to protect Hindus, their interests.

A Hindu temple in Pakistan's Punjab province was reportedly vandalized by hundreds of people after a nine-year-old Hindu boy, who allegedly urinated at a local seminary, received bail, a media report said on Thursday.

According to the Dawn news report, the incident took place on Wednesday in Bhong town, about 60 km from Rahim Yar Khan city.

Besides the vandalization, the mob also blocked the Sukkur-Multan Motorway (M-5), the report added.

Citing sources, Dawn news said that a case was registered against the minor on July 24 based on a complaint filed by a cleric, Hafiz Muhammad Ibrahim, of the Darul Uloom Arabia Taleemul Quran.

The sources said that "some Hindu elders did tender an apology to the seminary administration saying the accused was a minor and mentally challenged".

But, when a lower court granted him bail a few days ago, some people incited the public in the town on Wednesday and got all shops there closed in protest, the report quoted the sources as further saying.

A video clip showing people wielding clubs and rods storming the temple and smashing its glass doors, windows, lights, and damaging the ceiling fans went viral on social media.
