Dinosaur-killing asteroid could hold the cure for cancer

London: A 10-km wide asteroid that wiped out dinosaurs when it crashed into earth over 65 million years ago contains a rare metal — iridium — that could be used in the effective treatment of cancer, researchers have found.

Scientists from the UK and China have demonstrated that iridium — a rare metal delivered to Earth by the asteroid — can be used to kill cancer without harming healthy cells.


Laser-based techniques are emerging as viable treatments for cancer, targeting tumours far more precisely than the shotgun blast of radiation and chemotherapy. Researchers from the University of Warwick in the UK and Sun Yat-Sen University in China have found that laser light can turn iridium into an effective cancer killer, the newatlas.com reported.

The team created a compound of iridium and organic materials, and then introduced it into a lung cancer tumour grown in the lab. When red laser light is shone onto it through the skin, the compound is activated, converting the oxygen in the tumour into singlet oxygen, a poisonous form of the element that effectively kills the cancer cells from the inside. With cancer becoming resistant to certain treatments, it’s crucial to find new methods such as this.

Further study found that the compound was effective as it managed to penetrate every layer of the tumour.

The team used ultra-high resolution mass spectrometry to highlight which proteins in the cancer cells were being targeted. They found that the compound had damaged proteins that manage heat shock stress and glucose metabolism, which are known to be crucial molecules for cancer’s survival.

When the researchers tested the iridium compound on a clump of non-cancerous tissue they found it had no effect, meaning it seems to be a highly targeted treatment that doesn’t attack healthy cells. The research was published in the journal Angewandte Chemie.

Iridium is relatively rare on Earth naturally, but scientists have found a spike in the Chicxulub crater, an impact crater buried underneath the Yucatán Peninsula in Mexico, which is often associated with the asteroid impact that wiped out the dinosaurs.

“The precious metal platinum is already used in more than 50 per cent of cancer chemotherapies,” says Peter Sadler, lead author of the study. “The potential of other precious metals such as iridium to provide new targeted drugs that attack cancer cells in completely new ways and combat resistance, and which can be used safely with the minimum of side-effects, is now being explored. It’s certainly now time to try to make good medical use of the iridium delivered to us by an asteroid 66 million years ago!” — IANS

Diwali is known for gifting and jewellery tops the list, with the focus on buying gold and diamonds.

Diwali is known for gifting and jewellery tops the list, with the focus on buying gold and diamonds. ORRA jewellery, a trusted diamond jewellery brand is gearing up for the festive and bridal season. As they open their 50th store in the country, IANSlife caught up with Dipu Mehta, Managing Director, ORRA, to find out how the company plans to ramp up its now 50 company-owned and operated stores, expanding its retail presence in Tier-1 and 2 cities and target the millennial segment.

Read Excerpts:

Q: The brand is expanding in tier-2 and tier-3 cities, is brick and mortar the way forward to create a presence in this segment?

A: ORRA currently is expanding in metros plus tier-2 cities. But we aren't opening stores in any new markets. We are only opening in markets where we are already present. We are increasing the number of stores within cities as the demand for jewellery buying has also increased. Currently, we are present in 25 cities with 50 stores, and by the end of the month, we would be launching another seven stores.
Also with a category like jewellery, it is important to have brick and mortar stores as the customers like to see and hold higher value jewellery before purchasing. Jewellery buying is an important decision to the customers and having a store gives them that assurance.

The Centre on Wednesday directed all Union Ministries and Departments to clear Air India's dues immediately.

The Centre on Wednesday directed all Union Ministries and Departments to clear Air India's dues immediately. An office memorandum from the Finance Ministry's Department of Expenditure said: "Recently, the Government of India has decided to disinvest Air India, and the process of disinvestment of Air India and Air India Express is ongoing."

"Air India has stopped extending credit facilities on account of purchase of air tickets. Therefore, all Ministries or Departments are directed to clear Air India's dues immediately." "Air tickets from Air India may be purchased in cash till further instructions."



In 2009, the Centre had mandated that Central government officers travel via Air India for all official purposes including availing of LTC. On Monday, conglomerate Tata Group entered into a share purchase agreement with the Central government for buying out the latter's stake in national carrier Air India, Air India Express, and AISATS.

Sports betting has become increasingly popular among the youth in recent times

Sports betting has been around for centuries for the audience to not only watch the sport but to get more deeply involved in the match. It is a fun and often profitable activity for the viewer to win some extra fortune or simply get some extra sweat while watching the game. At first glance, sports betting may look like it's pure luck, but when you indulge deeper into the activity you realize it is more of a calculative and research activity than just pure luck. We must note that yes, luck does play a certain role to some extend but a win is not completely dependent on luck, if you're putting your bets on a certain team you have to make sure to do some research about the players on the team, history of wins and losses of the team and compare the probability of winning and then place bets.

Even though sports betting has existed since the ancient era, it was not until recently that it became increasingly popular among the youth. This happened due to the legalization of the activity and the rise of online sports betting. The technological revolution has expanded the sports betting industry, offering the bettors new markets and ways to bet. The only major difference between online bookmarkers and traditional brick-and-mortar venues of sports betting is that now you can place bets online from your mobile devices, laptops, computers etc.
