Cancer remains a medical mystery despite all of the research efforts devoted to understanding and controlling it. The most sought-after tumor model is one that would be able to formulate theoretical and computational tools to predict cancer progression and propose individual treatment strategies.

To better understand the role complex tumor-host interactions play in tumor growth, Princeton University researchers developed a cellular automation model for tumor growth in heterogeneous microenvironments. They then used this same model to investigate the effects of pressure on the growth of a solid tumor in a confined heterogeneous environment, such as a brain cancer growing in the cranium, and discovered that pressure accumulated during tumor growth can lead to a wide spectrum of growth dynamics and morphologies for both noninvasive and invasive tumors.

Depending on the magnitude of the pressure and the physical properties of the host environment, the types of tumor patterns that emerge range from strongly malignant tumors characterized by finger-like protrusions at the tumor surface to those in which fingering growth is diminished. These results should have important applications for cancer diagnosis, prognosis, and therapy.

Police arrest suspect in killing of 5 in SF home

(AP) ? A 35-year-old man was arrested Sunday in the gruesome killing of five people in a San Francisco home, police said.

Binh Thai Luc, a San Francisco resident, was taken into custody Sunday morning and booked on five counts of murder, Police Chief Greg Suhr said.

The bodies of the three women and two men were found early Friday by a woman with access to the home in the southern part of the city. Police said the crime scene was so tangled that police couldn't determine the cause of deaths.

"This was a complex crime scene. We had five deceased persons apparently from blunt force trauma. We didn't know what we had," Suhr said.

He declined to release details of the arrest or what led investigators to Luc.

He also did not say whether investigators have determined a motive for the killings, saying only that Luc knew the victims and that an "edged weapon" was involved in the slayings.

India to continue Iran oil import without violating law

New Delhi: India plans to continue import of crude oil from Iran without violating any international law, Oil Minister S Jaipal Reddy said on Friday.

"We have a systematic plan for receiving oil from Iran," he told reporters on sidelines of the Asia Gas Partnership Summit.

"We are envisaging no cut (in purchase of crude oil from Iran)," he said while asking the United States and other western nations to take into account India's oil needs.

India bought about 18 million tons or 12 per cent of its needs from Iran worth about $12 billion.

India to continue Iran oil import without violating law

The US had earlier this week exempted Japan and 10 European nations from its financial sanctions because they cut imports from Iran, but left India and China out of the list.

"We continue to receive representations from the US and other countries. We respect their sentiments (but) we have requested them to appreciate our need," he said.

India is Iran's second-biggest oil client after China. It bought about 18 million tons or 12 per cent of its needs from Iran worth about $12 billion.

"Our companies need oil from Iran and we will continue to import without violation of international law in letter and spirit," he said. "However, I would like to take this opportunity to assure the consumers that there will be no problem of supplies at all."

Is the Bottom In for Real Estate ETFs? | ETF Trends

The real estate market has been stuck in a lull for years now, but Wall Street?s so-called smart money is expecting a recovery in housing. Investors who believe in a continued rebound may take a look at real estate-related exchange traded fund options.

While housing starts numbers were weaker-than-expected for February, January data was revised upward and building permits rose 5.1% to pre-2008 financial crisis levels, reports Aaron Task for The Daily Ticker.

?The thinking is we?ve bottomed out and we?re going slowly start rebounding in terms of pricing,? Greg Zuckerman of The Wall Street Journal said in the report. ?Over the last couple of months some of the best investors on the street?have been making big bets on homebuilders.?

Firms like SAC Capital, Blackstone and Caxton Associates are among the funds taking on a greater weighting in homebuilders. [Homebuilder ETFs Double S&P 500?s Return]

Housing market bulls point to real estates? low affordability as a result of low interest rates, heavy price slashes since the 2006 highs and pent-up demand from new families and young adults. [Real Estate: List of REIT ETFs]

However, the naysayers note that home prices are still high on a historic basis and prices have yet to fall below fair value, which usually occurs after a bubble. Additionally, they add that there is still a ?shadow inventory,? foreclosures are rising, unemployment remains elevated and Treasury yields are increasing.

Existing home sales dropped 0.9% in February from January to 4.59 million, but it was still the strongest February in five years, report Allan Zibel and Eric Morath for The Wall Street Journal. The National Association of Realtors stated that February sales were 8.8% higher year-over-year and the first two months of the year showed the strongest start since 2007.

?We feel very good about the latest sales trend,? said Lawrence Yun, National Association of Realtors? top economist. ?Buyers are very serious this year.?

Housing-related ETFs are among the best performers, including:

  • SPDR S&P Homebuilders ETF (NYSEArca: XHB): up 25.0% year-to-date
  • iShares Dow Jones u.S. Home Construction Index Fund (NYSEArca: ITB): up 25.8% year-to-date
  • iShares Dow Jones U.S. Real Estate Index Fund ETF (NYSEArca: IYR): up 9.9% year-to-date
