Imaging glucose uptake activity inside single cells Posted: 17 Jul 2015 08:07 PM PDT A new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance has been described by researchers. The team developed a new glucose analogue that can mimic the natural glucose, and imaged its uptake as energy source by living cancer cells, neurons and tissues at the single cell level.

Researchers discover a possible reason for drug resistance in breast tumors Posted: 17 Jul 2015 12:36 PM PDT Amplified levels of HER2 membrane proteins drive unrestricted cell growth in certain types of breast cancer. HER2-tailored antibody-based therapeutics aim to prevent cancer cell growth. However, two-thirds of the patients develop resistance against such therapeutics. Why, is not yet understood. Researchers now found out that HER2 dimers appeared to be absent from a small sub-population of resting SKBR3 breast cancer cells. This subpopulation may have self-renewing properties and thus may be resistant to antibody therapy.

Improved way to interpret high-throughput biological data Posted: 17 Jul 2015 09:03 AM PDT A recent study reveals a novel workflow, identifying associations between molecules to provide insights into cellular metabolism and gene expression in complex biological systems.

New malaria treatment thwarts parasite resistance Posted: 17 Jul 2015 07:14 AM PDT As increasing resistance in parasites undermines the effectiveness of current drugs, two new compounds are raising hopes in the ongoing battle against malaria, scientists report.

Human heart-on-a-chip screens drugs for potential benefit, harm Posted: 17 Jul 2015 06:23 AM PDT A novel system for growing cardiac tissue from undifferentiated stem cells on a culture plate has been developed by scientists. This heart on a chip is a miniature physiologic system that could be used to model early heart development and screen drugs prescribed during pregnancy.

Breeding a better peanut butter Posted: 17 Jul 2015 06:23 AM PDT A new variety of peanut, called OLé, has recently been released by a team of researchers. OLé peanuts have longer shelf lives and increased disease resistance compared to other peanut varieties, and pack high amounts of a heart-healthy fatty acid called oleic acid.

Some like it sweet, others not so much: It's partly in the genes Posted: 17 Jul 2015 06:19 AM PDT A single set of genes accounts for approximately 30 percent of person-to-person variance in sweet taste perception, regardless of whether the sweetener is a natural sugar or a non-caloric sugar substitute, a new study suggests.

Research shows how to reduce cost of modern investment strategies Posted: 16 Jul 2015 05:54 PM PDT New research shows how investors can significantly reduce the cost of implementing portfolio strategies – in some cases by more than 90 per cent. The study shows that many modern investment strategies often lead to low returns or even lose money in practice, as they are prone to large trading costs. Such costs include bid-ask spreads, brokerage fees and capital gain taxes and can dramatically affect investment returns, turning an otherwise winning strategy into a losing one.

Cooper's hawk abundance gives researcher insight on other raptor biology Posted: 16 Jul 2015 03:11 PM PDT A six year study on Cooper's Hawks in urban Albuquerque is underway. The study will help the New Mexico Fish and Wildlife Service learn new information on the biology of all raptors.

Health-care providers hold biases based on sexual orientation, study says Posted: 16 Jul 2015 03:09 PM PDT In the first study that looks at a variety of health-care providers and their implicit attitudes towards lesbian women and gay men, researchers found there is widespread implicit bias toward lesbian women and gay men. The study finds that moderate to strong implicit preferences for straight people over lesbian and gay people are widespread among heterosexual providers.

Health researchers far behind industry using automation, leaves critical research unfunded Posted: 16 Jul 2015 03:09 PM PDT The National Institutes of Health has experienced funding cuts even as the number of scientists has grown significantly. University laboratories are closing, faculty positions are being cut, less life-saving research is being conducted, and researchers are spending considerably more time writing grants, and much less time actually doing research. More efficient means of conducting research will be needed if scientific progress is to continue, experts say in a new report.

Researchers identify genetic markers linking risk for both type 2 diabetes, Alzheimer’s disease Posted: 16 Jul 2015 01:10 PM PDT A study sheds light on the influences of genetics on why some type 2 diabetics are at high risk for developing Alzheimer's disease. While previous studies strongly suggested a causative role of diabetes in the onset and progression of Alzheimer's disease dementia, the specific mechanistic interactions connecting diabetes and Alzheimer's disease had not been previously described.

Unprecedented worldwide biodiversity study Posted: 16 Jul 2015 01:06 PM PDT Humans depend on high levels of ecosystem biodiversity, but due to climate change and changes in land use, biodiversity loss is now greater than at any time in human history. A leading global initiative is underway to determine whether there are widespread and consistent patterns in plant biodiversity.
