MU Psychology Study Finds Key Early Skills for Later Math Learning

*Long-term study shows students must know about numbers at beginning of first grade*

COLUMBIA, Mo. – Psychologists at the University of Missouri have identified the beginning of first grade math skills that teachers and parents should target to effectively improve children’s later math learning.

A long-term psychology study indicates that beginning first graders that understand numbers, the quantities those numbers represent, and low-level arithmetic will have better success in learning mathematics through the end of fifth grade, and other studies suggest throughout the rest of their lives.

‘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…)

Berkeley Scientists Pioneer Nanoscale Nuclear Materials Testing Capability

Nuclear power is a major component of our nation’s long-term clean-energy future, but the technology has come under increased scrutiny in the wake of Japan’s recent Fukushima disaster. Indeed, many nations have called for checks and “stress tests” to ensure nuclear plants are operating safely.

In the United States, about 20 percent of our electricity and almost 70 percent of the electricity from emission-free sources, including renewable technologies and hydroelectric power plants, is supplied by nuclear power. Along with power generation, many of the world’s nuclear facilities are used for research, materials testing, or the production of radioisotopes for the medical industry. The service life of structural and functional material components in these facilities is therefore crucial for ensuring reliable operation and safety. (more…)

Breaking the Chain: ‘Molecular cap’ Blocks Processes that Lead to Alzheimer’s, HIV

A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer’s disease and prevent the sexual transmission of HIV.

The researchers report that they have designed molecular inhibitors that target specific proteins associated with Alzheimer’s disease and HIV to prevent them from forming amyloid fibers, the elongated chains of interlocking proteins that play a key role in more than two dozen degenerative and often fatal diseases.

‘America’s Deadliest War Also is Most Memorialized’

As the nation recognizes the 150th anniversary of the Civil War’s start, public interest has been rekindled in the war and the numerous memorials and monuments marking historic figures, sites and battlegrounds in states around the country.

South Carolina militiamen fired the first shots of the Civil War at Fort Sumter on April 12, 1861, and over the next four years more than 10,000 military engagements between the North and South took place. In the end more than 600,000 soldiers died. (more…)

UFO for American Presidents

Many U.S. presidents during their terms were seriously interested in UFOs and extraterrestrial intelligence issues, and some of them even had a chance to make contact with aliens. We turn to the recently declassified archives of ufology. Let’s start with 1948, when President Harry S. Truman summoned his Assistant Robert Landry to the Oval Office.

Truman gave him the order to make reports every three months on the flying saucers observed over the country. Once, Truman asked to investigate the case of the appearance of mysterious object over Washington that he observed through his window. (more…)

Air Quality Worsened by Paved Surfaces

*Widespread urban development alters weather patterns*

New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.

The international study, led by the National Center for Atmospheric Research (NCAR), could have implications for the air quality of fast-growing coastal cities in the United States and other mid-latitude regions overseas. (more…)

With Global Warming, Arctic Access Will Diminish By Land But Improve By Sea

Global warming over the next 40 years will cut through Arctic transportation networks like a double-edged sword, limiting access in certain areas and vastly increasing it in others, a new UCLA study predicts.

“As sea ice continues to melt, accessibility by sea will increase, but the viability of an important network of roads that depend on freezing temperatures is threatened by a warming climate,” said Scott Stephenson, a UCLA graduate student in geography and the study’s lead author. (more…)
