How exercise grows a healthy heart
The findings may have clinical implications, particularly for those with heart failure or other conditions that make exercise difficult to impossible, the researchers say.

TU scientists in Nature: Better control of building blocks for quantum computer
Scientists from the Kavli Institute of Nanoscience at TU Delft and Eindhoven University of Technology in The Netherlands have succeeded in controlling the building blocks of a future super-fast quantum computer.

Gatekeeper for tomato pollination identified
Having identified a tomato pollen gene associated with blocking self-pollination in petunias and cross-species fertilization in tomatoes, researchers at the University of California, Davis, conclude that tomato plants use similar biochemical mechanisms to guard against inbreeding and cross-species hybridization.

Kidney disease patients: Eat your veggies, reward your kidneys
Phosphorous levels plummet in kidney disease patients who stick to a vegetarian diet, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology.

6 years after the tsunami disaster
Six years after the tsunami disaster of Dec. 26, 2004, the set-up of the German-Indonesian Tsunami Early Warning System for the Indian Ocean (GITEWS) has been completed.

Heat shock protein drives yeast evolution
Whitehead Institute researchers have determined that heat shock protein 90 (Hsp90) can create diverse heritable traits in brewer's yeast by affecting a large portion of the yeast genome.

Finding new ways to tackle environmental diseases
Researchers at the University of Exeter have developed a new approach to studying potentially deadly disease-causing bacteria which could help speed up the process of finding vaccines.

Dana Farber/Harvard Cancer Center awarded $11.7M grant to support prostate cancer research
Dana Farber/Harvard Cancer Center has been awarded $11.7 million in unclaimed funds from the Lupron class action settlement to launch a grant award program focused on prostate cancer research that emphasizes large-scale research collaborations on a national level and smaller-scale innovative pilot projects.

Protein involved in early steps of melanoma development revealed
Protein required for early stages of melanoma development can also predict melanoma outcome.

You are what your father ate too
We aren't just what we eat; we are what our parents ate too.

Study on effects of resveratrol and quercetin on inflammation and insulin resistance
A study was carried out to examine the extent to which quercetin and trans-resveratrol prevented inflammation or insulin resistance in primary cultures of human adipocytes treated with tumor necrosis factor-a (TNF-a) -- an inflammatory cytokine elevated in the plasma and adipose tissue of obese, diabetic individuals.

SU scientists find that in the evolutionary mating game, brawn and stealth rule
When prowling for a hook up, it's not always the good-looker who gets the girl.

Texas A&M research shows bacteria provide example of one of nature's first immune systems
Studying how bacteria incorporate foreign DNA from invading viruses into their own regulatory processes, Thomas Wood, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is uncovering the secrets of one of nature's most primitive immune systems.

How cells running on empty trigger fuel recycling
Researchers at the Salk Institute for Biological Studies have discovered how AMPK, a metabolic master switch that springs into gear when cells run low on energy, revs up a cellular recycling program to free up essential molecular building blocks in times of need.

Ben-Gurion U researcher reveals newspapers' historic resistance to granting reporters' bylines
Professor Zvi Reich explains that the byline is a relatively new phenomenon in the history of journalism and that newspapers as respected as the New York Times went out of their way to avoid using bylines as a means of underplaying the importance of the individual reporters.

Texas A&M professor helps develop first high-temp spin-field-effect transistor
An international team of researchers featuring Texas A&M University physicist Jairo Sinova has announced a breakthrough that gives a new spin to semiconductor nanoelectronics and the world of information technology.

Electronic medical records not always linked to better care in hospitals, study finds
Use of electronic health records by hospitals across the United States has had only a limited effect on improving the quality of medical care, according to a new RAND Corporation study.

Gene alteration in mice mimics heart-building effect of exercise
By tweaking a single gene, scientists have mimicked in sedentary mice the heart-strengthening effects of two weeks of endurance training, according to a report from Dana-Farber Cancer Institute and Beth Israel Deaconess Medical Center.

Fat cells become useful stem cells in tissue reconstruction
Stem cells derived from fat cells have potential for use in plastic surgery and tissue reconstruction because they share properties with bone marrow cells, can be found in abundance, and can be autologously donated.

Some brain tumors mimic the genetic program of germline cells
Scientists at IRB Barcelona have discovered that some brain tumors in larvae of the fruit fly Drosophila melanogaster use the genetic program of germline cells to grow.

A new model to predict poor maternal outcomes in pre-eclampsia
A new model to predict adverse maternal outcomes in pre-eclampsia is discussed in an Article published online first by the Lancet.

Tech firm joins the 'billion dollar club' -- with university help
The latest success of Martek Biosciences, a rising-star among Maryland biotechs, began more than a decade ago in a plain, brick building on the University of Maryland campus.

UCLA researchers uncover new cell biological mechanism that regulates protein stability in cells
The cell signaling pathway known as Wnt, commonly activated in cancers, causes internal membranes within a healthy cell to imprison an enzyme that is vital in degrading proteins, preventing the enzyme from doing its job and affecting the stability of many proteins within the cell, researchers at UCLA's Jonsson Comprehensive Cancer Center have found.

Back to the dead (sea, that is)
A new study led by professor Zvi Ben-Avraham of Tel Aviv University's Minerva Dead Sea Research Center is digging underneath the Dead Sea to reveal the historical health of the planet through the last 500,000 years -- and to learn more about what climate change may hold in store for our planet.

Nuclear magnetic moments
SCIENCE CHINA: Physics, Mechanics & Astronomy will publish a special issue on nuclear magnetic moments and related topics in February 2011.

You are what your father ate
Scientists at the University of Massachusetts Medical School and the University of Texas at Austin have uncovered evidence that environmental influences experienced by a father can be passed down to the next generation, is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
