Biosimilar Drugs Key to Saving Billions in Health Care

November 4, 2014 7:00 am | by RAND Corporation | News | Comments

Introducing competing biosimilar versions of complex biologic drugs used to treat illnesses such as cancer and rheumatoid arthritis could cut spending on biologics in the U.S. by $44 billion over the next decade, according to new analysis from a nonprofit research organization.

Calcium Oxide Can Improve Cattle Diets

November 4, 2014 7:00 am | by Purdue Univ. | News | Comments

Research has shown that small amounts of calcium oxide can neutralize the acid in distillers grains, a commonly used alternative to corn in many livestock feed mixes. The findings are good news for beef producers hoping to provide a more nutritious, better balanced diet to their animals while keeping their feed budgets manageable.

Process Yields Valuable Chemicals from Wood, Crop Waste

November 3, 2014 2:00 pm | by Univ. of Wisconsin-Madison | News | Comments

Scientists today disclosed a new method to convert lignin, a biomass waste product, into simple chemicals. The innovation is an important step toward replacing petroleum-based fuels and chemicals with biorenewable materials.

Test May Fight Preventable Blindness in Africa

November 3, 2014 2:00 pm | by PATH | News | Comments

A new test will accelerate global progress toward eliminating onchocerciasis, a leading cause of preventable blindness in Africa. An international nonprofit health organization, has announced the availability of an antibody-based test that is faster, easier-to-use and more acceptable to impacted communities than the current option.

Method Turns Antibodies to Tuned Nanobodies

November 3, 2014 2:00 pm | by Rockefeller Univ. | News | Comments

Antibodies, in charge of recognizing and homing in on molecular targets, are among the most useful tools in biology and medicine. Nanobodies– antibodies’ tiny cousins– can do the same tasks, for example marking molecules for research or flagging diseased cells for destruction. But, thanks to their comparative simplicity, nanobodies offer the tantalizing prospect of being much easier to produce.

Genetic Toolkit Helps Maximize Crop Yields

November 3, 2014 6:00 am | by Cold Spring Harbor Laboratory | News | Comments
