Misunderstanding of palliative care leads to preventable suffering

A new review says palliative care's association with end of life has created an "identity problem" that means the majority of patients facing a serious illness do not benefit from treatment of the physical and psychological symptoms that occur throughout their disease. The editorial is co-authored by palliative care experts at Harvard Medical School, Massachusetts General Hospital, the American Cancer Society, and Johns Hopkins University, and appears in the New England Journal of Medicine.

The colors of nature: 9 beautiful new wasp species from China

A new study provides seventeen records of the cuckoo wasp genus Cleptes from China, nine of which are beautifully coloured new to science species. The study, published in the open access journal ZooKeys, is the first revision of the genus from China, providing morphological data and illustrations.

Zebrafish help decode link between calcium deficiency and colon cancer

ANN ARBOR—A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.

By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells.

Saving the Great Plains water supply

Significant portions of the Ogalalla Aquifer, one of the largest bodies of water in the United States, are at risk of drying up if it continues to be drained at its current rate.

In the current issue of Earth's Future, a journal of the American Geophysical Union, Michigan State University scientists are proposing alternatives that will halt and hopefully reverse the unsustainable use of water drawdown in the aquifer. The body of water, also known as the High Plains Aquifer, spans from Texas to South Dakota and drives much of the region's economy.

New organization brings together top researchers to sequence genomes of invertebrates

FORT LAUDERDALE-DAVIE, Fla. – Pop Quiz: what creatures make up more than 70% of the approximately 1.9 million described species on earth and have long served as model organisms in many areas of biology? If you guessed invertebrates, you're right!

To begin exploring this question, a new cooperative consortium called the Global Invertebrate Genomics Alliance (GIGA) was formed and held its inaugural workshop at Nova Southeastern University's (NSU) Oceanographic Center in March 2013.

New gene discovery sheds more light on Alzheimer's risk

A research team from The University of Nottingham has helped uncover a second rare genetic mutation which strongly increases the risk of Alzheimer's disease in later life.

In an international collaboration, the University's Translational Cell Sciences Human Genetics research group has pinpointed a rare coding variation in the Phospholipase D3 (PLD3) gene which is more common in people with late-onset Alzheimer's than non-sufferers.

UCLA stem cell scientists first to track joint cartilage development in humans

Stem cell researchers from UCLA have published the first study to identify the origin cells and track the early development of human articular cartilage, providing what could be a new cell source and biological roadmap for therapies to repair cartilage defects and damage from osteoarthritis.

Such transformative therapies could reach clinical trials within three years, said the scientists from UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research.

Researchers hope newly discovered gene interaction could lead to novel cancer therapies

Scientists from Virginia Commonwealth University Massey Cancer Center have revealed how two genes interact to kill a wide range of cancer cells. Originally discovered by the study's lead investigator Paul B. Fisher, M.Ph., Ph.D., the genes known as mda-7/IL-24 and SARI could potentially be harnessed to treat both primary and metastatic forms of brain, breast, colon, lung, ovary, prostate, skin and other cancers.

New presurgery combination therapy may improve outcomes for women with triple-negative breast cancer

SAN ANTONIO — The I-SPY 2 trial, an innovative, multidrug, phase II breast cancer trial, has yielded positive results with the first drug to complete testing in the trial. Adding the chemotherapy carboplatin and the molecularly targeted drug veliparib to standard presurgery chemotherapy improved outcomes for women with triple-negative breast cancer, according to results from the I-SPY 2 trial presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.

New combination therapy fails to delay progression of advanced breast cancer

SAN ANTONIO — Adding the antibody therapy ramucirumab to the chemotherapy drug docetaxel did not delay disease progression for patients with HER2-negative, advanced breast cancer, according to results of a placebo-controlled, randomized, phase III clinical trial presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.

Bisphosphonate treatment fails to improve outcomes for women with chemoresistant breast cancer

SAN ANTONIO — Treatment with the bisphosphonate zoledronate did not improve outcomes for women with chemoresistant breast cancer, according to initial results of a phase III clinical trial presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.

New presurgery treatment combination more effective for women with triple-negative breast cancer

SAN ANTONIO — Adding the chemotherapy drug carboplatin and/or the antibody therapy bevacizumab to standard presurgery chemotherapy increased the number of women with triple-negative breast cancer who had no residual cancer detected at surgery, according to results of a randomized, phase II clinical trial presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10–14.

A stop sign for cancer

Proteins in cells communicate like relay runners in a competition. The sticks that are transferred between the runners are the "signals". These signals are passed within the cell from one protein to another and ensure cell growth and survival. In cancer cells it is interesting approach to block this information cascade and thereby block the proliferation of cancer cells.

New discovery on how skin cells form 'bridges' paves the way for advances in wound healing

A team of researchers from the National University of Singapore (NUS) have discovered that outer skin cells are able to unite to form suspended "bridges" during wound healing. The new findings will pave the way for tissue engineering, such as the design of artificial skin, and better wound treatment.

True story: Not everyone lies frequently

Washington, DC (December 10, 2013) – Does everybody lie? We are taught that this is common sense and that most people tell little white lies. But perhaps this isn't true. A recent paper published in Human Communication Research found that many people are honest most of the time, that many are honest about their lying, and that some lie a lot.
