Heart muscle cell grafts suppress arrhythmias after heart attacks in animal study
New study finds link between cell division and growth rate
Researchers have made a major advance in efforts to regenerate damaged hearts. Grafts of human heart muscle cells reduced the incidence of irregular heart rhythms after heart attacks in animal studies. Grown from embryonic stem cells, the grafted cells couple electrically and contract in sync with the heart's own muscle. The results offer evidence that human heart muscle cell grafts meet...
New study helps predict impact of ocean acidification on shellfish
A new study finds a link between cell division and growth rate.
New technology eliminates plant toxins
An international study to understand and predict the likely impact of ocean acidification on shellfish and other marine organisms living in seas from the tropics to the poles is published this week in the journal Global Change Biology.
Out of Europe
A team of researchers from the University of Copenhagen have developed a method to hinder unwanted toxins from entering the edible parts of plants such as the oilseed rape, which will make it suitable for animal feed.
Researchers discover new mechanism behind resistance to cancer treatment
Researchers show that access to clean water might not reduce the incidence of dysentry as a country becomes more developed. As countries become more industrialized, and improve health, lifestyle and access to clean water, the numbers of infections with dysentery-causing Shigella flexneri decline. However, incidence of another form of the dysentery-causing bacterium, Shigella sonnei, increase with...
Sequencing of malaria genomes reveals challenges, opportunities in battle against parasite
Developing resistance to chemotherapy is a nearly universal consequence for cancer patients with solid tumors -- such as those of the breast, prostate, lung and colon -- that have metastasized, or spread, throughout the body. A team of scientists led by Fred Hutchinson Cancer Research Center has discovered a key factor that drives this drug resistance -- information that ultimately may be used to...
Understanding the biological and ecological implications of safe nanotechnology
Genetic variability revealed in malaria genomes newly sequenced by two multi-national research teams points to new challenges in efforts to eradicate the parasite, but also offers a better picture of its genetic composition, providing an initial roadmap in the development of vaccines to combat malaria.
White blood cells mediate insulin resistance
The researchers' paper, "Dendrimer-fullerenol soft-condensed nanoassembly" published in the Journal of Physical Chemistry C, showed how the soft nanomaterial dendrimer can be used to remediate the environment from potentially toxic nanomaterials.
Droughts show global warming is 'scientific fact'
Researchers at the University of California, San Diego School of Medicine say neutrophils, an abundant type of white blood cell typically tasked with attacking bacteria and other foreign invaders, also plays an unexpected role in mediating insulin resistance -- the central characteristic of type 2 diabetes, which afflicts an estimated 26 million Americans.
Pitch by Yankees’ Freddy Garcia Tests Physics Experts
The relentless, weather-gone-crazy type of heat that has blistered the U.S., Canada and other parts of the world in recent years is so rare it can't be anything but man-made global warming, a new statistical analysis says.

Like the male antechinus mouse, the oversexed often fail to find loveAt just 11 months, the male antechinus mouse reaches sexual maturity. He searches his territory every night, hoping to satisfy his voracious sexual appetite. The escalating hormones lead him to 12-hour sexual encounters and mating sprees that span up to four days (all without stopping to eat, drink or rest with his...

New study ties global warming to recent year heat
It’s an age-old question: Does success have more to do with talent and effort, or simply good fortune? Sociologists found some answers in an experiment with 48 songs by indie bands.
TWiDN: Immortality Means Lots of Ice Cream
An analysis by a top government scientist says the extreme heat and drought seen in the U.S., Europe and other regions in recent years must be global warming. Specifically the study by NASA scientist James Hansen blames climate change for last year's drought in Texas and Oklahoma, the 2010 heat wave in Russia and the 2003 European heat wave that led to tens of thousands of...
