Food additive key to environmentally friendly, efficient, plastic solar cells

An efficient, semi-printed plastic solar cell has now been created without the use of environmentally hazardous halogen solvents.

Urban warming slows tree growth, photosynthesis

New research finds that urban warming reduces growth and photosynthesis in city trees. The researchers found that insect pests are part of the problem, but that heat itself plays a more significant role.

Social media photos priceless for natural resources research

Tapping into social media posts on Instagram, Flickr and Panoramio gave researchers a trove of information about people’s opinions of scenic European landscapes. A new study shows that geotagged photos – complete with millions of comments – can provide data for predictive models to help guide land use policy, conservation planning and development decisions worldwide.

Kelp beats the heat

Using long-term ecological data, marine scientists evaluate the sentinel status of giant kelp during a recent marine heat wave.

New insight into eye diseases

Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, known as Muller glial cells (MGs), do serve as retinal stem cells that are capable of generating new cells. In a new study, a research team investigated whether the regenerative power of cells in zebrafish could be recreated in mammals, specifically mice.

Evaluation of scientific rigor in animal research

The “reproducibility crisis” in biomedical research has led to questions about the scientific rigor in animal research, and thus the ethical justification of animal experiments. In new research, scientists have assessed scientific rigor in animal experimentation in Switzerland. The study found widespread deficiencies in the reporting of experimental methodology.

Gut microbes linked to immunotherapy response in melanoma patients

Patients with malignant melanoma - whose disease has spread - are more likely to respond to immunotherapy treatment if they had greater diversity in their gut bacteria, according to new research.

The urge to upgrade

In order to properly decide if an upgrade is worth the cost, consumers should compare the new product with what they already own. But new research shows there‘s a wide gap between what buyers should do and what actually happens when it comes to the most cutting-edge gadgets, products and services.

New evidence shifts the timeline back for human arrival in the americas

Humans occupied South America earlier than previously thought, according to the recent discovery of ancient artifacts found at an archeological site in Argentina.
