Galaxy NGC 4696 hosts a complex globular cluster system, observations find

Using the Magellan Telescopes in Chile, astronomers have performed photometric observations of a giant elliptical galaxy known as NGC 4696. The observations reveal that the galaxy has a complex globular cluster system. The ...

An alternative way to manipulate quantum states

Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.

LSD use tied to increased distress in unemployed job-seekers

Lifetime LSD use is associated with a higher likelihood of severe psychological distress after losing one's job, according to a new study published in the open-access journal PLOS ONE by Benjamin Korman, formerly of the University ...

How calcium reduces macrocracking in sweet cherries

Researchers at the University of Hannover have uncovered new insights into the mode of action of calcium in the reduction of macrocracking in sweet cherry fruit. The findings shed light on the mechanisms underlying this phenomenon, ...

When divided loyalties make for better executives

It's well-known that servants with two masters are often conflicted. But they can also be uniquely knowledgeable, especially when one master wants to know what the other is up to, or the interests of the two coincide.

Next-generation NASA technologies tested in flight

Teams of NASA researchers put their next-generation technologies to the microgravity test in a series of parabolic flights that aim to advance innovations supporting the agency's space exploration goals.

Economists reveal the costs of sanctions

What effect do economic sanctions have on the countries affected, such as Russia or Iran? What impact do they have on the sanctioning states? And is there possibly an ideal coalition of sanction partners? Economists from ...

Mandating vaccination could reduce voluntary compliance

Citizen opposition to COVID-19 vaccination has emerged across the globe, prompting pushes for mandatory vaccination policies. But a new study based on evidence from Germany and on a model of the dynamic nature of people's ...

Plants get a faster start to their day than we think

To describe something as slow and boring we say it's "like watching grass grow", but scientists studying the early morning activity of plants have found they make a rapid start to their day—within minutes of dawn.

Innovative batteries put flying cars on the horizon

Jet packs, robot maids and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical ...

New COVID-19 model reveals effectiveness of travel restrictions

More strategic and coordinated travel restrictions likely could have reduced the spread of COVID-19 in the early stages of the pandemic. That's according to new research published in Communications Physics. This finding stems ...

New breakthrough in hot embossing technology

Korean researchers have developed a new hot embossing process technology that can freely imprint fine circuit patterns on flexible polymer substrate. The result is expected to be used in semiconductor processes, wearable ...

Researchers offer solution in fight against fake graphene

Ever since the isolation of graphene was first achieved in 2004, there has been an explosion in graphene-related research and development, with hundreds of business opportunists producing graphene to capitalise on this rapidly ...

A chip with blood vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

No pause in global warming in the past 100 years

Global warming has been attributed to persistent increases in atmospheric greenhouse gasses (GHGs), especially in CO2, since 1870, the beginning of the Industrial Revolution. Nevertheless, the upward trend in global mean ...
