Scientists propose a spray that will make the most aggressive brain cancer tumors commit suicide. This spray contains bio-nanoantennae, special molecules that can alter cells at the quantum level.

Scientists at the University of Nottingham have devised a unique spray treatment method to cure glioblastoma, a highly aggressive brain cancer that annually kills over 10,000 people in the US.

The Sentinel system facilitates extended stays underwater, allowing scientists to reside at depths of up to 200 meters for as long as 28 days.

In a bold initiative, DEEP, a leading research organization, has announced plans to construct an underwater habitat open to the public by 2027. Named Sentinel, this modular subsea abode aims to revolutionize underwater living, research, and observation by providing scientists unprecedented access to the depths of the ocean.

The Sentinel system is designed to facilitate extended stays underwater, allowing scientists to reside at depths of up to 200 meters for as long as 28 days. This innovative habitat offers a unique opportunity for researchers to study… More.

For years, the wind energy industry has adopted the three-blade model for its turbines. As the world looks for cleaner sources of energy, the turbines are getting larger and are also going deeper into the seas, where winds blow stronger.

Mental preparation — and the ability to laugh at ourselves — can ensure that frustrating failures lead to great breakthroughs.

A network that connects quantum devices and a central server that spans Hefei, China, can allow multiple secure quantum chats at once.

Pandemic, renovation project, and rising costs create logistics nightmare for NSF-funded scientists.

Metal-enhanced photoluminescence is able to provide a robust signal even from a single emitter and is promising in applications in biosensors and optoelectronic devices. However, its realization with semiconductor nanocrystals (e.g., quantum dots, QDs) is not always straightforward due to the hidden and not fully described interactions between plasmonic nanoparticles and an emitter. Here, we demonstrate nonclassical enhancement (i.e., not a conventional electromagnetic mechanism) of the QD photoluminescence at nonplasmonic conditions and correlate it with the charge exchange processes in the system, particularly with high efficiency of the hot-hole generation in gold nanoparticles and the possibility of their transfer to QDs.

One of the most interesting and important questions in cosmology is, “How much matter exists in the universe?” An international team, including scientists at Chiba University, has now succeeded in measuring the total amount of matter for the second time. Reporting in The Astrophysical Journal, the team determined that matter makes up 31% of the total amount of matter and energy in the universe, with the remainder consisting of dark energy.

“Cosmologists believe that only about 20% of the total matter is made of regular or ‘baryonic’ matter, which includes stars, galaxies, atoms, and life,” explains first author Dr. Mohamed Abdullah, a researcher at the National Research Institute of Astronomy and Geophysics-Egypt, Chiba University, Japan. “About 80% is made of dark matter, whose mysterious nature is not yet known but may consist of some as-yet-undiscovered subatomic particles.”

“The team used a well-proven technique to determine the total amount of matter in the universe, which is to compare the observed number and mass of galaxy clusters per unit volume with predictions from numerical simulations,” says co-author Gillian Wilson, Abdullah’s former graduate advisor and Professor of Physics and Vice Chancellor for research, innovation, and economic development at UC Merced.

After years of dedicated research and over 5 million supercomputer computing hours, a team has created the world’s first high-resolution 3D radiation hydrodynamics simulations for exotic supernovae. This work is reported in The Astrophysical Journal.

Ke-Jung Chen at Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) in Taiwan, led an international team and used the powerful supercomputers from the Lawrence Berkeley National Laboratory and the National Astronomical Observatory of Japan to make the breakthrough.

Supernova explosions are the most spectacular endings for massive stars, as they conclude their life cycles in a self-destructive manner, instantaneously releasing brightness equivalent to billions of suns, illuminating the entire universe.
