False memories of self-performance result from watching others' actions
- ScienceDaily
- 10/9/14 21:23
Did I turn off the stove, or did I just imagine it? Memory isn't always reliable. Psychological scientists have discovered all sorts of ways that false memories get created, and now there's another one for the list: watching someone else do an action can make you think you did it...

Making cookies that are good for your heart
- ScienceDaily
- 10/9/14 21:23
Years of research has proven that saturated and trans fats clog arteries, make it tough for the heart to pump and are not valuable components of any diet. Unfortunately, they are contained in many foods. Now, a research team has developed a soybean which produces oil that is naturally low in saturated and trans...
Androgen receptor may explain male dominance in liver cancer
- ScienceDaily
- 10/9/14 21:22
A new study helps to explain why men get liver cancer more often than women and opens the door for a new treatment pathway, by showing a direct link between the androgen receptor, which is more active in men, and the hepatitis B virus as it relates to the deadly cancer.

An initial analysis suggests that biomarkers in blood serum can be combined with clinical information to accurately classify patients with Alzheimer's disease, according to a new study.
Targeted agent shows promise for chronic lymphoid leukemia
- ScienceDaily
- 10/9/14 07:23
New research may have identified an experimental agent that targets chronic lymphocytic leukemia (CLL) and perhaps other proliferative disorders of lymphocytes. This study using tumor cells from patients shows that the small-molecule inhibitor CAL-101 directly promotes cell death in CLL cells and disrupts several external survival pathways needed for CLL cell viability and proliferation. The...
2010 was fourth warmest U.S. summer on record
- ScienceDaily
- 10/9/14 07:23
The contiguous United States had its fourth-warmest summer (June-August) on record, according to the latest NOAA State of the Climate report. The report also showed the August average temperature was 75.0 degrees F, which is 2.2 degrees F above the long-term (1901-2000) average. Last month's average precipitation was 2.41 inches, 0.19 inch below the 1901-2000...
Childhood cancer survivors show sustained benefit from common ADHD medication

A medicine widely used to treat attention-deficit/hyperactivity disorder (ADHD) also provides long-term relief from the attention and behavior changes that affect many childhood cancer survivors, according to a multicenter trial.
New metabolic markers may predict preeclampsia in early pregnancy
- ScienceDaily
- 10/9/14 07:23
Researchers identified 14 new markers that could identify in early pregnancy who may be at risk of developing preeclampsia in later pregnancy. Preeclampsia is a life-threatening condition characterized by high blood pressure and high levels of protein in the urine.

If the water looks and smells bad, it may be toxic
- ScienceDaily
- 10/9/14 07:23
Earthy or musty odors, along with visual evidence of blue-green algae, also known as cyanobacteria, may serve as a warning that harmful cyanotoxins are present in lakes or reservoirs. In a new study of cyanobacterial blooms in Midwest lakes, taste-and-odor compounds were found almost every time cyanotoxins were found, indicating odor may serve as a warning that harmful toxins are...
