When Viruses Infect Bacteria

*Looking in vivo at virus-bacterium associations sets stage for better understanding of such interactions in human health*

Viruses are the most abundant parasites on Earth. Well known viruses, such as the flu virus, attack human hosts, while viruses such as the tobacco mosaic virus infect plant hosts.

More common, but less understood, are cases of viruses infecting bacteria known as bacteriophages, or phages. In part, this is due to the difficulty of culturing bacteria and viruses that have been cut off from their usual biological surroundings in a process called in vitro. (more…)

Some Russians Still Live in The USSR

The Soviet passport stopped its existence seven years ago. Nevertheless, about 5,000 residents of the city of Sverdlovsk live in a non-existent country. They refuse to exchange their ID for a Russian passport. What is the reason behind such absurd situations? Do those people feel nostalgic about the erstwhile superpower or are they stuck-in-the-mud kind of people? What can be done about such citizens who can not even be referred to as citizens?

A local news agency says that many of those “Soviet passport people” ask officers of migration services to glue in new photos in their invalid passports. Some others decide not to exchange their Soviet passports for Russian ones in order not to pay the state duty of 1,000 rubles ($30). There are people who say that the new passport insults their religious feelings. (more…)

‘Combining Therapies Appears Safe, May Benefit Patients with Advanced Liver Cancer’

GAINESVILLE, Fla. — Few treatments exist for patients with advanced primary liver cancer, but University of Florida researchers have found a new way to broaden the range of options and potentially improve health outcomes by combining two treatments.

In the first study of its kind, the researchers combined sorafenib, the only Food and Drug Administration-approved pill for treating advanced liver cancer, with another routinely used therapy known as transarterial chemoembolization, which works by cutting off the blood supply to tumors. No unexpected toxic effects were seen, and the combo appears to have the potential to improve survival for certain groups of patients. (more…)

Being Small Has Its Advantages, If You Are a Leaf

The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA life scientists goes a long way toward solving it. (more…)

Children Who Seldom Smile, Laugh or Hug a Parent Might be at Risk for Depression

ANN ARBOR, Mich.— A new study from the University of Michigan and the University of Pittsburgh shows that even if a child isn’t crying, frowning or displaying other negative emotions on a consistent basis, another warning sign is when a child shows fewer positive displays, like hugging a parent or smiling and laughing.

“Surprisingly, it seems that it is low levels of happiness, as opposed to high levels of sadness, what may help explain why these kids too often develop depressive disorders,” said Nestor Lopez-Duran, an assistant professor of psychology at U-M and one of the study’s authors. (more…)

Earliest Image of Egyptian Ruler Wearing “White Crown” of Royalty Brought to Light

The earliest known image of an Egyptian ruler wearing the “White Crown” associated with Egyptian dynastic power has been brought to light by an international team of archaeologists led by Egyptologists from Yale University.

Carved around 3200 BCE, this unique record of a royal celebration at the dawn of the Egyptian dynastic period was found at a site discovered almost a half-century ago by Egyptologist Labib Habachi at Nag el-Hamdulab, on the West Bank of the Nile to the north of Aswan. (more…)

Mastering Disaster: Students Create Software to Save Lives

*At the Imagine Cup 2011 Worldwide Finals, dozens of student teams showcase software projects that in some cases are already improving disaster relief efforts.*

REDMOND, Wash. – July 7, 2011 – When floodwaters swept across northern Thailand last fall, Kriangkrai Pipatvilaikul knew he had to help. So he boarded a bus with fellow students from Chulalongkorn University and went to a devastated village he had seen on TV.

The students joined scores of volunteers arriving at the same village with food, water and medical supplies. As they helped with the relief effort, the group heard about a harder hit area, one that hadn’t made the news, and they decided to push on. What they found shocked them. As they paddled through the submerged town, desperate villagers surrounded their boat and tried to grab whatever food they could. The students realized no other volunteers had been there despite the short distance from the previous site. (more…)

Cassini Captures Images and Sounds of Saturn Storm

PASADENA, Calif. — Scientists analyzing data from NASA’s Cassini spacecraft now have the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth.

On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears approximately 35 degrees north latitude of Saturn. Pictures from Cassini’s imaging cameras show the storm wrapping around the entire planet covering approximately 2 billion square miles (4 billion square kilometers). (more…)
