Millimeter wave photonics with terahertz semiconductor lasers
The volume of wireless telecommunication traffic is expected to surge in the near future with a continual increase in data traffic and corresponding necessary increases in bandwidth. It has therefore become imperative to increase the photon frequency.....»»
Scientists prove long-standing wave amplification theory
Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by bouncing "twisted waves"—those with angular moment.....»»
Electrically modulated light antenna points the way to faster computer chips
Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz—which corresponds to several billion computing operations per second......»»
Surf therapy connects people to water—ocean health depends on this "blue attunement"
As a lifelong surfer, born to pioneering surfing parents and named after a wave, the ocean has shaped my identity and sense of belonging. The movement and touch of ocean waves ignites a whole cascade of changes in emotions in me and affects how I sen.....»»
Evacuations ordered as wildfire burns in foothills of national forest east of LA
Evacuations were ordered Saturday as a wildfire scorched the foothills of a national forest east of Los Angeles, amid a days-long heat wave that pushed temperatures into the triple digits across the region......»»
Improved method for phonon lasers "locks" sound waves into a more stable and powerful state
Scientists have made a significant leap in developing lasers that use sound waves instead of light. These phonon lasers hold promise for advancements in medical imaging, deep-sea exploration, and other areas......»»

Scientists demonstrate giant THz Kerr effect via stimulated phonon polaritons
Terahertz (THz) waves and THz technologies have gradually opened a new style for communications, cloud-based storage/computing, information contest, and medical tools. With the advancement of THz technologies, studies on THz nonlinear optics have eme.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Five lessons from ancient civilizations for keeping homes cool in hot, dry climates
Modern buildings tend to take electricity and air conditioning for granted. They often have glass facades and windows that can't be opened. And when the power goes out for days in the middle of a heat wave, as the Houston area experienced in July 202.....»»
Air conditioning poses a climate conundrum
This week, much of the US is suffering from yet another heat wave. So far this year, 15 countries have set records for high heat. Last July, the average global temperature, factoring in heat waves in multiple regions around the world, was likely the.....»»
Advances in semiconductor patterning: New block copolymer achieves 7.6 nm line width
A recently developed block copolymer could help push the limits of integration and miniaturization in semiconductor manufacturing, report scientists at Tokyo Institute of Technology (Tokyo Tech) and Tokyo Ohka Kogyo (TOK). Chemically tailored for rel.....»»
During a heat wave, "stay indoors" can bring hazards, too
With Chicago and much of the Midwest facing what may be the hottest days of the summer this week, many are cranking up the air conditioning and heeding the advice of officials to stay inside......»»
