Researchers from the University of Maine and Penn State discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are attracted to each other or are repelled by each other. In our everyday experience, however, interactions don’t seem to follow this reciprocal law. For example, a predator is attracted to prey, but the prey tends to flee from the predator. Such non-reciprocal interactions are essential for complex behavior associated…

The research team has successfully developed unprecedented “NK cell-engaging nanodrones” capable of selectively targeting and eliminating cancer cells, offering a potential solution for intractable types of cancers. The innate lymphoid cells known as natural killer (NK) cells play a vital role in the body’s immune response against cancer. Numerous efforts have…
Researchers from Osaka University have identified a protein called HKDC1 that’s crucial to maintaining two subcellular structures, mitochondria and lysosomes, thereby preventing cellular senescence. Just as healthy organs are vital to our well-being, healthy organelles are vital to the proper functioning of the cell. These subcellular structures carry out specific jobs within the cell, for example, mitochondria power the cell and lysosomes keep the cell tidy. Although damage to these two organelles has been linked to aging, cellular senescence, and…
An international research group has engineered a novel high-strength flexible device by combining piezoelectric composites with unidirectional carbon fiber (UDCF), an anisotropic material that provides strength only in the direction of the fibers. The new device transforms kinetic energy from the human motion into electricity, providing an efficient and reliable means for high-strength and self-powered sensors. Details of the group’s research were published in the journal Small on Dec.14, 2023. Motion diction involves converting energy from the human motion into measurable electrical…
Li-fi, a communication technology harnessing visible light for data transmission, has a potential to surpass Wi-Fi’s speed by over 100 times and boasts a high bandwidth, facilitating the simultaneous transmission of copious information. Notably, Li-fi ensures robust security by exclusively transmitting data to areas illuminated by light. Most importantly, it capitalizes on existing indoor lighting infrastructure, such as LEDs, eliminating the need for separate installations. However, implementing visible light communication (VLC) in practical lighting systems posed an issue of diminished…
For decades, a substantial number of proteins, vital for treating various diseases, have remained elusive to oral drug therapy. Traditional small molecules often struggle to bind to proteins with flat surfaces or require specificity for particular protein homologs. Typically, larger biologics that can target these proteins demand injection, limiting patient convenience and accessibility. In a new study published in Nature Chemical Biology, scientists from the laboratory of Professor Christian Heinis at EPFL have achieved a significant milestone in drug development….
A research team, led by Professor Yongwon Seo in the Graduate School of Carbon Neutrality at UNIST has unveiled a highly efficient method for desalinating seawater using hydrate-based desalination (HBD) technology. The breakthrough is expected to have far-reaching implications for the application of hydrate-based desalination techniques, with the ability to calculate optimal temperatures for enhanced efficiency. Hydrate desalination technology, known for its eco-friendly freshwater production capabilities, offers a low-energy solution that can be effectively used in treating high concentrations of brine or…
More sustainable and economical. This new method is based on the exsolution process activated by microwave radiation. Exsolution is a method of generating metallic nanoparticles on the surface of ceramic materials. “At elevated temperatures and in a reducing atmosphere (usually hydrogen), metal atoms migrate from the structure of the material to its surface, forming metal nanoparticles anchored to the surface. This anchoring significantly increases the strength and stability of these nanoparticles, which positively impacts the efficiency of these catalysts,” explains…
New theoretical analysis places the likelihood of massive neutron stars hiding cores of deconfined quark matter between 80 and 90 percent. The result was reached through massive supercomputer runs utilizing Bayesian statistical inference. Neutron-star cores contain matter at the highest densities reached in our present-day Universe, with as much as two solar masses of matter compressed inside a sphere of 25 km in diameter. These astrophysical objects can indeed be thought of as giant atomic nuclei, with gravity compressing their…
Installation of a tungsten divertor for long pulse operations.

This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies, along with quasars, host one of the most common subclasses of AGN. While the precise categorization of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby and their central AGN does not outshine…
A drug screening system that models cancers using lab-grown tissues called organoids has helped uncover a promising target for future pancreatic cancer treatments, according to a new study from researchers at Weill Cornell Medicine.
