Molecular alterations in head and neck cancers uncovered by study

Science Daily - Wed, 28/01/2015 - 7:16pm
A new study shows genomic differences in head and neck cancers caused by infection with the human papillomavirus. In addition, researchers have uncovered new smoking-related cancer subtypes and potential new drug targets, and found numerous genomic similarities with other cancer types. Together, this study's findings may provide detailed explanations of how HPV infection and smoking play roles in head and neck cancer risk and disease development, and offer potential diagnostic and treatment directions.

Quantum computer as detector shows space is not squeezed

Science Daily - Wed, 28/01/2015 - 7:16pm
Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions -- that it's not squeezed in one direction relative to another. A new experiment by physicists used partially entangled atoms -- identical to the qubits in a quantum computer -- to demonstrate more precisely than ever before that this is true: to one part in a billion billion.

Missing link in metal physics explains Earth's magnetic field

Science Daily - Wed, 28/01/2015 - 7:16pm
Earth's magnetic field shields the life on our planet's surface from cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means it can easily conduct a flow of electrons. New findings show that a missing piece of the traditional theory explaining why metals become less conductive when they are heated was needed to complete the puzzle of this field-generating process.

Damaged DNA may stall patrolling molecule to initiate repair

Science Daily - Wed, 28/01/2015 - 7:14pm
Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. These finding suggest that the delay itself may be the key that allows the protein molecule to find its target, according to researchers.

Protein pathway involved in nicotine-induced lung cancer metastasis found

Science Daily - Wed, 28/01/2015 - 7:14pm
Smoking is the leading cause of lung cancer, and it is estimated that more than 159,000 people in the United States died from the disease last year. Most of these deaths were because the cancer had spread to other organ sites. Following their recent discovery of a protein pathway, researchers are one step closer to understanding how lung cancer cells metastasize.

Nobel Laureate and Laser Inventor Charles Townes Passes

Slashdot - Wed, 28/01/2015 - 6:52pm
An anonymous reader writes Charles Hard Townes, a professor emeritus of physics at the University of California, Berkeley, who shared the 1964 Nobel Prize in Physics for invention of the laser and subsequently pioneered the use of lasers in astronomy, died early Tuesday in Oakland. He was 99. "Charlie was a cornerstone of the Space Sciences Laboratory for almost 50 years,” said Stuart Bale, director of the lab and a UC Berkeley professor of physics. “He trained a great number of excellent students in experimental astrophysics and pioneered a program to develop interferometry at short wavelengths. He was a truly inspiring man and a nice guy. We’ll miss him.”

The Digital Divide Is Not Binary

Wired News - Wed, 28/01/2015 - 6:45pm

Economic growth and social inclusion, critical issues for many countries, will be promoted by bringing the four-plus billion non-Internet users around the world online. The common view of this digital divide is that it separates the Internet “haves” from the “have-nots”; dividing those who are online from those who would like to get online, but […]

Chimps with higher-ranking moms do better in fights

Playing with puzzles, blocks may build children's spatial skills

Science Daily - Wed, 28/01/2015 - 6:13pm
Play may seem like fun and games, but new research shows that specific kinds of play are actually associated with development of particular cognitive skills. Data from an American nationally representative study show that children who play frequently with puzzles, blocks, and board games tend to have better spatial reasoning ability. Being able to reason about space, and how to manipulate objects in space, is a critical part of everyday life, helping us to navigate a busy street, put together a piece of furniture, even load the dishwasher. And these skills are especially important for success in particular academic and professional domains, including science, technology, engineering, and math (STEM).

Anthropology: Ancient skull from Galilee cave offers clues to the first modern Europeans

Science Daily - Wed, 28/01/2015 - 6:13pm
The discovery of a 55,000-year-old partial skull in Northern Israel provides new insights into the migration of modern humans out of Africa. A key event in human evolution was the expansion of modern humans of African origin across Eurasia, replacing all other forms of hominin (humans and their predecessors), around 40,000-60,000 years ago. However, due to the scarcity of human fossils from this period, these ancestors of all present-day non-African modern populations have largely remained a mystery. Now, researchers describe a partial skull that dates to around 55,000, which was found at Manot Cave in Israel's Western Galilee.
