World's first toxicology testing strategy without animal testing adopted by OECD

Success for long-standing collaboration between BASF and Givaudan to develop and validate alternative methods

30-Jun-2021

The world’s first toxicology testing strategy without animal testing has been approved by the OECD (Organisation for Economic Co-operation and Development). The testing strategy consists of three so-called alternative methods. They can be used to predict whether a substance causes allergic ...

A sharper look at the interior of semiconductors

A research team is developing a high-resolution imaging technique that can be used to determine internal structures in materials and their chemical composition in a non-destructive manner and with nanometre precision

19-Feb-2021

Images provide information – what we can observe with our own eyes enables us to understand. Constantly expanding the field of perception into dimensions that are initially hidden from the naked eye, drives science forward. Today, increasingly powerful microscopes let us see into the cells and ...

Growth factors in single cells counted for the first time

26-Feb-2019

Whether healthy or diseased, human cells exhibit behaviors and processes that are largely dictated by growth factor molecules, which bind to receptors on the cells. For example, growth factors tell the cells to divide, move, and when to die--a process known as apoptosis. When growth factor levels ...

Shaping light lets 2D microscopes capture 4D data

Invention adds new dimension to fluorescent microscopy

20-Feb-2019

Rice University researchers have added a new dimension to their breakthrough technique that expands the capabilities of standard laboratory microscopes. Two years ago, the Rice lab of chemist Christy Landes introduced super temporal resolution microscopy, a technique that allowed researchers to ...

Tiny fibers create unseen plastic pollution

18-Feb-2019

While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve ...

Study fails to link phthalates and increased breast cancer risk

Epidemiologist says more research is needed looking at younger women

15-Feb-2019

In the largest study to date on phthalates and postmenopausal breast cancer, a University of Massachusetts Amherst cancer epidemiology researcher found no association between breast cancer risk and exposure to the plasticizing and solvent chemicals used in such common products as shampoo, makeup, ...

Cross-species cancer comparison uncovers new drug targets

Drug targets for a form of melanoma from genetic mutations found in humans, dogs and horses

13-Feb-2019

New drug targets for a rare form of melanoma may result from the discovery of similar genetic mutations found in humans, dogs and horses under a first-ever tri-species DNA sequencing study involving a University of Guelph researcher. Melanoma is a cancer that most commonly occurs in the skin in ...

Examining puzzling sizes of extremely light calcium isotopes

13-Feb-2019

Michigan State University researchers have measured for the first time the nuclei of three proton-rich calcium isotopes. One of the most fundamental properties of the nucleus is its size. The nuclear radius generally increases with the number of proton and neutron constituents. However, when ...

New insight into cell receptors opens the way for tailored cancer drugs

12-Feb-2019

New research on how cancer mutations influence a certain type of receptor on the cell membrane opens the way for the development of tailored drugs for certain cancers, such as rectal cancer and lung cancer. This according to researchers at Sweden's Karolinska Institutet and Uppsala University, ...
