Bird feeding helps females more than males

A new study from Lund University in Sweden shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as much as they would have otherwise, and the chances of surviving cold nights increase.

Creating a non-toxic alternative to colored smoke

Colored smoke is increasingly employed as an element of spectacle in a broad spectrum of public events. However, the chemicals used for this purpose give rise to toxic by-products. LMU chemists have now developed a safe alternative.

ATLAS Experiment searches for rare Higgs boson decays into a photon and a Z boson

The Higgs boson was discovered by the ATLAS and CMS Collaborations at CERN's Large Hadron Collider (LHC) in 2012 through its decays into pairs of photons, W bosons and Z bosons. Since then, physicists at these experiments have gained great insight into the properties of the Higgs boson through the study of its different production and decay processes. Decays to pairs of tau leptons and bottom...

Episode 7 - 50 Years of Apollo

From the historic Apollo splashdown to the future Artemis landing, we’re celebrating 50 years of human exploration and science on the Moon. This special edition of NASA Science Live will take viewers onboard the aircraft carrier that recovered the Apollo 11 capsule after splashdown – the USS Hornet. Join experts for a behind-the-scenes tour of this historic location where President...

Radioactive cloud over Europe had civilian background

A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe's radiation protection entities. Although the activity concentrations were innocuous, they reached up to 100 times the levels of what had been detected over Europe in the aftermath of the Fukushima accident. Since no government had assumed responsibility, a military...

Health profession: Social interdependence in active learning evaluated by Delphi procedure

Physicians must be competent collaborators with team members in order to practice medicine effectively. Health professional students have limited opportunities to work and learn together during the course of their medical education. Not only is it important for students to acquire prodigious knowledge, they must also learn how to collaborate well, and the results of their efforts must be evaluated...

Psychedelic therapy | Statues | Veganism | Boris Johnson | The Archers monologuesRobin Carhart-Harris says that the impact of psychedelic therapy is profound, with people experiencing emotional catharsis and physical rejuvenation (We can no longer ignore the potential of psychedelic drugs to treat depression, 8 June). Yet studies only focus on treating patients with depression. Why are these...

Radioactive cloud over Europe had civilian background

A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in 2017, is still bothering Europe's radiation protection entities. German researchers now found out that the cloud did not originate from military sources but rather from civilian nuclear activities.

Repairing thousands of disease-causing mutations

Researchers have created a new searchable library of base editors -- an especially efficient and precise kind of genetic corrector. Using experimental data from editing more than 38,000 target sites in cells with 11 of the most popular base editors (BEs), they created a machine learning model that accurately predicts base editing outcomes. Called BE-Hive, the library is free and open to the...
