Robotic clam digs in mudflats
To design a lightweight anchor that can dig itself in to hold small underwater submersibles, Anette Hosoi of MIT borrowed techniques from one of nature's best diggers -- the razor clam.

Generating electricity from air flow
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity.

Butterfly proboscis to sip cells
A butterfly's proboscis looks like a straw -- long, slender and used for sipping -- but it works more like a paper towel, according to Konstantin Kornev of Clemson University.

Gene mismatch influences success of bone marrow transplants
A commonly inherited gene deletion can increase the likelihood of immune complications following bone marrow transplantation, an international team of researchers reports in the Nov.

New cancer target for non-Hodgkin's lymphoma
Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer that affects lymphocytes, or white blood cells.

Beyond sunlight: Explorers census 17,650 ocean species between edge of darkness and black abyss
En route to historic first global Census of Marine Life (Oct.

Measuring and modeling blood flow in malaria
When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells.

New Vaccine edition on rotavirus burden data chronicles a decade of rotavirus surveillance in Asia
A special edition of the journal Vaccine broadens understanding of the tremendous burden caused by rotavirus disease, which is responsible for almost half of acute diarrhea hospitalizations among Asian children under five.

New drug regimen shows promising results for treating advanced biliary-tract cancers
Bevacizumab given in addition to the combined chemotherapy regimen of gemcitabine and oxaliplatin (GEMOX-B) is well tolerated and shows promising antitumour activity in patients with advanced biliary-tract cancers.

Burned out, depressed surgeons more likely to commit more major medical errors
Surgeons who are burned out or depressed are more likely to say they had recently committed a major error on the job, according to the largest study to date on physician burnout.

New hydrogen-storage method discovered
Scientists at the Carnegie Institution have found for the first time that high pressure can be used to make a unique hydrogen-storage material.

Surface bacteria maintain skin's healthy balance
On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable.

New understanding about mechanism for cell death after stroke leads to possible therapy
Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage.

New study links alcohol in pregnancy to child behavior problems
A new study from Perth's Telethon Institute for Child Health Research has found evidence that the amount and timing of alcohol consumption in pregnancy affects child behavior in different ways.

Nuclear weapons: Predicting the unthinkable
If a nuclear weapon were detonated in a metropolitan area, how large would the affected area be?

Bioengineers succeed in producing plastic without the use of fossil fuels
South Korean scientists succeed in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals, heralding the creation of environmentally conscious plastics.

Cancer metabolism discovery uncovers new role of IDH1 gene mutation in brain cancer
Agios Pharmaceuticals scientists have established, for the first time, that the mutated IDH1 gene has a novel enzyme activity consistent with a cancer-causing gene, or oncogene.

Aquatic creatures mix ocean water
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El NiƱo on our weather.
