Income level, literacy, and access to health care rarely reported in clinical trials
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.

Urban crime fell by over a third around the world during COVID-19 shutdowns, study suggests
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.

Coloring tumors reveals their bad influence
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.

Researchers identify how to prevent cancer metastases
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.

Clinical trial launched following discovery that psychiatric drug may prevent bowel cancer
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.

Hexagonal boron nitride's remarkable toughness unmasked
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.

World's lakes losing oxygen rapidly as planet warms
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.

Entangled quantum memories for a quantum repeater: A step closer to the Quantum Internet
* 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.

Astronomers discover a massive star cluster, of intermediate age, in the constellation Scutum
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.

Anyone can get super-hearing
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.

Current global environmental law and policy are failing, experts say
In 'Our Earth Matters: Pathways to a Better Common Environmental Future,' spanning two special issues of Environmental Policy and Law (EPL), leading scholars from more than five continents call for an honest introspection of what has been attained over the last 50 years relating to regulatory processes and laws and explore future trajectories with new ideas and frameworks for environmental governance in the 21st century.

RUDN University chemists created cheap catalysts for ethanol conversion
RUDN University chemists proposed a new way to synthesize catalysts for the conversion of ethyl alcohol. The obtained materials are promising catalysts for the selective conversion of ethanol, which is an important stage in the development of an alternative technology for obtaining valuable chemical synthesis products based on plant raw materials.

Cancer-promoting Ras protein exists in a pair within cells
Researchers from Bochum and Osnabrück have gained new insights into the structure of the Ras protein, which acts as a molecular switch for cell growth and is involved in the development of cancer. With the help of fluorescence markings, they have demonstrated that the protein is deposited in a pair at the cell membrane, and with the very structure that they predicted in theory back in 2012.

Nanomaterials with laser printing
An interdisciplinary team from the Max Planck Institute of Colloids and Interfaces presents a laser-driven technology that enables them to create nanoparticles out of materials such as copper, cobalt and nickel oxides. At the usual printing speed, photoelectrodes are produced in this way, for example, for a wide range of applications such as the generation of green hydrogen.
