Energy efficiency labeling for homes has little effect on purchase price

A Norwegian research team found that energy efficiency labeling for homes has no significant effect on purchase price. The researchers conducted a thorough analysis of home sales data before and after the labeling system was introduced in Norway in 2010. They discovered that any apparent impact of the label was likely due to other fact...

Does cutting weekend allied health services hurt patients?

A study published in PLOS Medicine found that removing weekend allied health services from hospitals had no significant effect on patients' length of stay or adverse events. In fact, having no services was associated with a 2% reduction in length of stay and a 3% decrease in adverse events.

Tracking mosquitoes with your cellphone

Researchers at Stanford University developed a platform called Abuzz that uses cellphone recordings to track mosquito populations and distributions. The platform aims to create the world's largest network of mosquito surveillance, enabling targeted control efforts and reducing the burden of mosquito-borne diseases.

Chromosome organization emerges from 1-D patterns

Using computer models, researchers analyzed epigenetic marks to predict how chromosomes fold in three dimensions. By training a neural network on these marks, they were able to identify the structural types of chromatin and validate their findings with additional data.

Aliens may be more like us than we think

A new study published in the International Journal of Astrobiology suggests that aliens could have evolved in a similar way to humans, with natural selection playing a key role. The research uses evolutionary theory to predict the biological make-up and behavior of complex alien life forms.

Uncomfortable sight from an ancient reflex of the eye

A new study from Penn researchers shows that a reflexive system of the human eye also produces a conscious, visual experience that may be related to excessive light sensitivity. The findings suggest that people have brain activity and a visual experience in response to invisible light pulses that stimulate melanopsin cells.

Are the grandkids worth it? Climate change policy depends on how we value human population

A new study finds that reducing greenhouse gas emissions to protect future generations from environmental destruction could save tens of billions of dollars annually, especially in wealthier countries. By valuing human population differently, policymakers can make more informed decisions about climate policy.

Sight unseen

Researchers analyzed over 600 drug and breast cancer cell pairings, revealing significant changes in gene expression without affecting cell growth or survival. The study identified potential synergistic combinations of drugs, including trametinib and alpelisib, to overcome adaptive resistance mechanisms.

The advent of 'green' cattle

A new method of carbon footprinting for pasture-based cattle production systems can identify 'green' cattle within a herd, reducing greenhouse gas emissions. The study found that existing methods underestimates the impacts of poorly performing animals, which produce disproportionately large amounts of methane.

Microscopic defects make batteries better

Researchers found that microscopic defects in electrodes enable lithium to hop inside the cathode along multiple directions, increasing reactive surface area and allowing for more efficient exchange of lithium ions. This discovery challenges traditional thinking on how electrode shape should be optimized for battery performance.
