Optical imaging and characterization of weakly scattering phase objects, such as isolated cells, bacteria and thin tissue sections frequently used in biological research and medical applications, have been of significant interest for decades. Due to their optical properties, when these 'phase objects' are illuminated with a light source, the amount of scattered light is usually much less than the...

Information in computers is transmitted through semiconductors by the movement of electrons and stored in the direction of the electron spin in magnetic materials. To shrink devices while improving their performance—a goal of an emerging field called spin-electronics ("spintronics")—researchers are searching for unique materials that combine both quantum properties. Writing in Nature...

An insightful cross-disciplinary team of University of Hawai'i (UH) at Mānoa researchers, working for over a decade, published a study recently revealing that a key number of hours of darkness during the lunar cycle triggers mature "Hawaiian box jellyfish" (Alatina alata) to swim to leeward O'ahu shores to spawn.

Mysterious fast radio bursts release as much energy in one second as the Sun pours out in a year and are among the most puzzling phenomena in the universe. Now researchers at Princeton University, the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and the SLAC National Accelerator Laboratory have simulated and proposed a cost-effective experiment to produce and...

Texas A&M University researchers Dr. Sam Noynaert and Fred Dupriest recently presented results from a geothermal project that drastically reduced well-completion times and drill bit changeouts to an audience of mostly petroleum drillers. The Department of Energy (DOE) funded the project, which improves geothermal drilling practices with physics-based instruction and oil and gas techniques to lower...

New research by a team of researchers at the NYU Abu Dhabi (NYUAD) Smart Materials Lab published today in the journal Nature Communications demonstrates that organic crystals, a new class of smart engineering materials, can serve as efficient and sustainable energy conversion materials for advanced technologies such as robotics and electronics.

Fewer Australians are following the headlines – but there’s a fine line between switching off and staying connected to the worldGet our weekend culture and lifestyle email and listen to our podcastIt was during the second Sydney lockdown, in 2021, that Cass decided to unplug.“I was finding myself really anxious about the state of the world. And when I looked at the news, I was like,...

Iraq's Lake Hamrin, a once-vast reservoir northeast of Baghdad that is the sole source of water for irrigation across Diyala province, has nearly dried out, a senior official said Friday.

Besides planting milkweed in the garden, people interested in helping monarch butterflies might want to turn off the porch light.

When it comes to attitudes and behaviors among members of American political parties, the conventional wisdom is that hate is stronger than love. 

Scientists discover the enzymes responsible for the production of one of the most toxic and fast-acting neurotoxins associated with freshwater harmful algal blooms in lakes and ponds. The discovery revealed that guanitoxin-producing cyanobacteria are more prevalent than originally known in the United States, opening the possibility for new molecular diagnostic testing to better inform and protect...

A groundbreaking study has found the underlying cause and a potential treatment for infantile spasms -- intractable epilepsy common in babies and with limited treatment options.

Once dubbed 'forever chemicals,' per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname. Adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in just a few hours, reports a new study led by environmental engineers. The addition of iodide accelerates the speed of...

Detecting these T cells may lead to diagnostics to better detect heart disease--and disease severity--through a blood sample. The knowledge also brings researchers closer to developing a vaccine that dampens this dangerous immune cell activity to prevent atherosclerosis.

Children who spend more time playing adventurously have lower symptoms of anxiety and depression, and were happier over the first Covid-19 lockdown, according to new research.

Biologists say nighttime light pollution can interfere with the remarkable navigational abilities of monarchs, which travel as far as Canada to Mexico and back during their multi-generational migration. Researchers found that butterflies roosting at night near artificial illumination such as a porch or streetlight can become disoriented the next day because the light interferes with their...

Unlike fictional laser swords, real laser beams do not interact with each other when they cross -- unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing can give rise to beams with changed colors and directions.

A team found flaws in previous research that purported to show meditation could alter the brain's structure.

New research could lead to better treatment options for a rare but very lethal type of bacterial infection.

Conifer is more than 5000 years old, scientist estimates. But some experts are skeptical
