Voracious comb jellyfish 'invisible' to prey
Despite its primitive structure, the North American comb jellyfish can sneak up on its prey like a high-tech stealth submarine, making it a successful predator. Researchers, including one from the University of Gothenburg, have now been able to show how the jellyfish makes itself hydrodynamically

So that's why we're allergic to sun creams
What happens to sunscreens when they are exposed to sunlight?

Rutgers discovery paves way for development of efficient, inexpensive plastic solar cells
Rutgers physicists have discovered new properties in a material that could result in efficient and inexpensive plastic solar cells.

New discovery on the causes of contact allergy
The fragrances used in many household and skincare products can cause contact allergy when exposed to oxygen in the air, reveals research from the University of Gothenburg's Faculty of Science in conjunction with the University of Gothenburg to be presented at the dermatologist conference in Gothenburg.

Virtual research institute needed to unlock RNA's promise
A Europe-wide network of labs focusing on RNA research is needed to make the most of RNA's high potential for treating a wide range of diseases.

Gladstone scientists link hepatitis C virus infection to fat enzyme in liver cells
Scientists at the Gladstone Institute of Virology and Immunology (GIVI) have found that an enzyme associated with the storage of fat in the liver is required for the infectious activity of the hepatitis C virus (HCV).

Prolonging first-line chemotherapy improves outcomes for patients with metastatic breast cancer
Contrary to what many oncologists believe, patients with metastatic breast cancer live longer on average if their chemotherapy is continued after their cancer is brought under control, a new meta-analysis shows.

Researchers develop oral delivery system to treat inflammatory bowel diseases
Researchers at Georgia Tech and Emory University have developed a novel approach for delivering small bits of genetic material into the body to improve the treatment of inflammatory bowel diseases.

Studies provide new insights into the genetics of obesity and fat distribution
An international consortium has made significant inroads into uncovering the genetic basis of obesity by identifying 18 new gene sites associated with overall obesity and 13 that affect fat distribution.

New definition of Alzheimer's disease could help select patients for trials of disease-modifying treatments
A new lexicon that revises and unifies the definition of Alzheimer's disease (AD) to include recent developments in the field, in which biomarkers are the key to diagnosis, has been proposed by an international group of Alzheimer's disease experts.

New findings on autoimmune diseases
A deficiency in one of the immune system's enzymes affects the severity of autoimmune diseases such as MS, and explains why the course of these diseases can vary so much.

New clues on how cancer spreads
Researchers have dramatically advanced medicine's understanding of how cancer migrates, showing that cancer cells are accompanied by growth-enabling stromal cells when they travel in the bloodstream to new sites in the body.

Cetuximab did not add significant benefit to NORDIC FLOX regimen in first line treatment of mCRC
Adding the targeted drug cetuximab to a three-drug chemotherapy regimen for first-line treatment of metastatic colorectal cancer does not improve response rate, progression-free survival or overall survival, researchers reported at the 35th Congress of the European Society for Medical Oncology in Milan, Italy.

Tsunami risk higher in Los Angeles, other major cities
Geologists studying the Jan. 12 Haiti earthquake say the risk of destructive tsunamis is higher than expected in places such as Kingston, Istanbul, and Los Angeles.

Iniparib extends overall survival in metastatic triple-negative breast cancer
Women with an aggressive subtype of metastatic breast cancer appear to live an average of almost five months longer when treated with iniparib plus chemotherapy, compared to chemotherapy alone, the results of a randomized phase-II trial show

Land 'evapotranspiration' taking unexpected turn: huge parts of world are drying up
The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa and South America, have been drying up in the past decade, a group of researchers conclude in the first major study to ever examine

Scientists watch cell-shape process for first time
Researchers at the Carnegie Institution for Science, with colleagues at the Nara Institute of Science and Technology, observed for the first time a fundamental process of cellular organization in living plant cells: the birth of microtubules by studying recruitment and activity of individual protein complexes that create the cellular protein network known as the microtubule cytoskeleton -- the scaffolding that provides structure and ultimately form and shape to the cell.

Melanoma drug shrinks brain metastases in phase I/II study
A new drug being developed to treat potentially deadly melanoma skin cancers has shown a promising ability to shrink secondary tumors, known as metastases, in the brain in patients with advanced forms of the disease, Australian researchers report.

Novocure reports data showing TTF therapy in combination with chemotherapy has the potential to increase overall survival for patients with advanced non-small cell lung cancer
Novocure reported today that patients with advanced non‑small cell lung cancer (NSCLC) achieved a significant increase in survival time when electrical fields delivered by its TTF wearable device were added to chemotherapy, as compared to previously reported outcomes for chemotherapy alone.

Scripps Research study challenges conventional theory of modern drug design
Scientists from the Scripps Research Institute have uncovered new evidence that challenges the current theory about a process key to the way modern drugs are designed and how they work in the human body.

Study finds breast-feeding safe for women after breast cancer treatment
Women who have survived breast cancer should not be denied the opportunity to breast-feed their children, say researchers who presented the results of a new study at the 35th Congress of the European Society for Medical Oncology in Milan, Italy.

Research discovers how the deaf have super vision
Deaf or blind people often report enhanced abilities in their remaining senses, but up until now, no one has explained how that could be.

Most Italian breast cancer patients older and diagnosed very early
A study of breast cancer in Italian women has found that more than 70 percent of those affected by the disease are over the age of 50 years, and the disease is identified before it has spread to the lymph nodes in more than 60 percent of cases.

Struggling for breath
Patients with a common chest deformity known as sunken chest exhibit abnormal breathing patterns.

High response rates seen in phase-III trial of chemotherapy, new drug and stem cells in myeloma
The first study of its kind comparing two different approaches to treating newly diagnosed multiple myeloma has found that both treatments achieved a positive response, researchers said at the 35th Congress of the European Society for Medical Oncology in Milan, Italy.
