Zebrafish exposed to the leading cannabinoids found in cannabis in the earliest stages of development suffer a significant drop in neural activity later in life, according to a University of Alberta study that has implications for prenatal development in humans.

A study conducted at the Oeschger Centre for Climate Change Research at the University of Bern provides new insights into the pollution of the world's oceans with plastic waste. The modelling shows that most of the plastic does not end up in the open ocean, but beaches or drifts in the water near the coast.

One-quarter of people who take the drug methotrexate for common immune system disorders -- from rheumatoid arthritis to multiple sclerosis -- mount a weaker immune response to a COVID-19 vaccine, a new study shows.

Influencing millions of people on social media and being paid handsomely is not as easy as it looks, according to new Cornell University research.

What drives the feasibility of climate scenarios commonly reviewed by organizations like the Intergovernmental Panel on Climate Change (IPCC)? And can they actually be achieved in practice? A new systematic framework can help understand what to improve in the next generation of scenarios and explore how to make ambitious emission reductions possible by strengthening enabling conditions.

High levels of aviation drive global warming, not only through greenhouse gas emissions, but also through additional clouds. This is the conclusion reached by scientists at Leipzig University, Imperial College London and the Institut Pierre-Simon Laplace in Paris.

Researchers at the Francis Crick Institute have identified a protein that helps tumours evade the immune system and, in certain types of cancers, is linked to a poorer chance of survival. The protein could become a target for future cancer treatments.

Experts at the Alfred Wegener Institute have, for the first time, experimentally measured the release of iron from the fecal pellets of krill and salps under natural conditions and tested its bioavailability using a natural community of microalgae in the Southern Ocean.

Clinical trials published in high-profile medical journals rarely report on income or other key sociodemographic characteristics of study participants, according to a new study that suggests these gaps may create blind spots when it comes to health care, especially for disadvantaged populations.

A new analysis of daily crime rates in 27 cities across 23 countries in Europe, the Americas, Asia and the Middle East has found that stay-at-home policies during the pandemic led to an overall drop in police-recorded crime of 37% across all sites in the study.

Red2Onco, an innovative genetic mouse model, allows to detect the very initial steps that lead to cancer development. Red2Onco's multi-colour labelling system allows to trace intestinal tumour development after the first oncogenic hit at the single cell level. The research carried out at IMBA - Institute of Molecular Biotechnology of the Austrian Academy of Sciences - and the University of Cambridge is now published in the journal Nature.

Metastases can develop in the body even years after apparently successful cancer treatment. They originate from cancer cells that migrated from the original tumor to other organs, and which can lie there inactive for a considerable time. Researchers have now discovered how these "sleeping cells" are kept dormant and how they wake up and form fatal metastases. They have reported their findings in the journal Nature.

The study, published in the journal Nature, shows how a drug available on the NHS can boost fitness of healthy stem cells in the gut, making them more resistant to sabotage from mutant stem cells that cause cancer.

The 2D material hexagonal boron nitride is so resistant to cracking that it defies a century-old theoretical description engineers still use to measure toughness, according to a study by Rice University and Nanyang Technological University in this week's issue of Nature.

Chinese researchers realized an elementary link of a quantum repeater based on absorptive quantum memories (QMs) and demonstrated the multiplexed quantum repeater for the first time.

Oxygen levels in the world's temperate freshwater lakes are declining rapidly -- faster than in the oceans -- a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.

* ICFO researchers report in Nature on having achieved, for the first time, entanglement of two multimode quantum memories located in different labs separated by 10 meters, and heralded by a photon at the telecommunication wavelength.* The study has been selected to grace the cover of Nature magazine.

An international team of astrophysicists led by the Stellar Astrophysics Group of the University of Alicante (UA), the Instituto de Astrofísica de Canarias (IAC), and the University of Valparaíso (Chile) has discovered a massive cluster of stars of intermediate age in the direction of the Scutum constellation. This object, which has been named Valparaíso 1, lies some seven thousand light years away from the Sun, and contains at least fifteen thousand stars.

Humans can observe what and where something happens around them with their hearing, as long as sound frequencies lie between 20 Hz and 20 000 Hz. Researchers at Aalto University have now developed a new audio technique that enables people to also hear ultrasonic sources that generate sound at frequencies above 20,000 Hz with simultaneous perception of their direction. The results have been published 2 June in Scientific Reports.

Smoking in early puberty in boys may have negative consequences for their future generations of offspring, a study from the University of Bergen (UiB) shows.
