Maternal exposure to chemicals linked to autistic-like behaviours in children

31-Mar-2021

A new study by Simon Fraser University's Faculty of Health Sciences researchers found correlations between increased expressions of autistic-like behaviours in pre-school aged children to gestational exposure to select environmental toxicants, including metals, pesticides, polychlorinated ...

New test to better assess environmental impact of substances

Researchers developed a test that investigates whether substances can cause inheritable changes in the genome of multicellular organisms such as insects

24-Nov-2020

Researchers of the Senckenberg Biodiversity and Climate Research Centre and the LOEWE Centre for Translational Biodiversity Genomics hope to increase the reliability of environmental impact tests of substances. To this end, they developed a test that investigates whether substances can cause ...

This bacterium gets paid in gold

Harvesting solar fuels through a bacterium's unusual appetite for gold

11-Oct-2018

A bacterium named Moorella thermoacetica won't work for free. But UC Berkeley researchers have figured out it has an appetite for gold. And in exchange for this special treat, the bacterium has revealed a more efficient path to producing solar fuels through artificial photosynthesis. M. ...

All-in-one light-driven water splitting

10-Sep-2018

Solar-powered water splitting is a promising means of generating clean and storable energy. A novel catalyst based on semiconductor nanoparticles has now been shown to facilitate all the reactions needed for “artificial photosynthesis”. In the light of global climate change, there is an urgent ...

Quantum Dot White LEDs Achieve Record Efficiency

16-Jul-2018

Researchers have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt. Luminous efficiency is a measure of how well a light source uses power to generate light. With further development, the new LEDs could reach ...

Don't Give the Slightest Chance to Toxic Elements in Medicinal Products

New high-accuracy reference solutions for the SI-traceable measurement

27-Mar-2018

Lead, cadmium, mercury, and arsenic do not belong in medicinal products. International requirements for the quality of medicines have therefore become more stringent and introduced new control requirements. Hence, it makes sense to use high-accuracy reference solutions with defined contents of ...

Inspectors find phthalates in toys and asbestos in second-hand products

Hundreds of consumer products with illegal amounts of restricted chemicals

13-Feb-2018

The project report shows a relatively high number of products on the European market containing chemicals that are restricted under REACH. Inspectors in 27 European countries checked 1 009 mixtures, 4 599 articles and 17 substances. Overall, out of 5 625 targeted product checks, 18 % did not ...

Engineers give optical switches the 'contrast' of electronic transistors

02-Feb-2018

Current computer systems represent bits of information, the 1's and 0's of binary code, with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on their inputs. As fast and powerful as computers have become, Ritesh Agarwal, ...

Drinking glasses can contain potentially harmful levels of lead and cadmium

07-Nov-2017

Enamelled drinking glasses and popular merchandise can contain potentially toxic levels of lead and cadmium, a study has shown. Researchers at the University of Plymouth carried out 197 tests on 72 new and second-hand drinking glass products, including tumblers, beer and wine glasses, and ...

Semiconductor dynamics may help improve energy efficiency

08-Sep-2017

Researchers examining the flow of electricity through semiconductors have uncovered another reason these materials seem to lose their ability to carry a charge as they become more densely "doped." Their results may help engineers design faster semiconductors in the future. Semiconductors are ...
