The UN's climate change conference COP27: Topics on the agenda

The UN's annual climate change conference is currently ongoing in Sharm el-Sheikh in Egypt. Over the course of two weeks, representatives of the world's nations will gather to discuss how to achieve the goals of the 2015 Paris Agreement and contribute to the climate transition.

Children's songs: A link to one's inner self and to others

Singing can be a real health boost. Song involves your emotions, thoughts and body; the feelgood hormone oxytocin surges and the stress hormone cortisol declines. Singing accompanies us from the cradle to the grave, and binds us together as human beings. But what do kids sing in school, how much, and in what way? David Johnson, researcher at the Malmö Academy of Music, investigates this in his...

Why go back to the Moon?

On September 12, 1962, then US president John F. Kennedy informed the public of his plan to put a man on the Moon by the end of the decade.

New experiment measures decay time for exotic nuclei

A new study led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has measured how long it takes for several kinds of exotic nuclei to decay. The paper, published today in Physical Review Letters, marks the first experimental result from the Facility for Rare Isotope Beams (FRIB), a DOE Office of Science user facility operated by Michigan State University.

Dams could play a big role in feeding the world more sustainably, researchers find

A bogeyman to many environmentalists, dams could actually play a significant role in feeding the world more sustainably, according to new Stanford University research. The study, published the week of Nov. 14 in Proceedings of the National Academy of Sciences, quantifies for the first time how much water storage would be required to maximize crop irrigation without depleting water stocks or...

Mini-engine exploits noise to convert information into fuel

Too much background noise is usually guaranteed to disrupt work. But physicists have developed a micro-scale engine–made from a glass bead–that can not only withstand the distracting influence of noise, but can harness it to run efficiently. Their experiment is reported in the journal Physical Review Letters and was selected by the journal as a research highlight.

Planning on asking for a high salary in a job interview? Think again

A new study conducted by Dr. Yossi Maaravi, dean of Reichman University's Adelson School of Entrepreneurship, and developmental psychologist Sandra Segal, former director of Dr. Maaravi's research lab, examined the psychological and financial consequences of high (but not extreme) demands in salary negotiations.

Researchers produce first-ever 'family tree' for aquarium-bred corals

Corals bred in public aquaria provide novel research opportunities and a healthy stock for outplanting into the wild, essential components of a thriving future for coral reef ecosystems, which support around 25% of all life in Earth's oceans. But the long-term success of such efforts hinges in part on maintaining genetic diversity in aquarium-bred corals which leads to increased resilience to...
