Researchers from UCLA have developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity, which could eventually lead to more advanced medical and security imaging systems. A UCLA Henry Samueli School of Engineering and Applied Science research team has developed a breakthrough broadband modulator […]

- Female bonobos could have become the dominant sex in their societies by deceiving males as to when they are likely to conceive, according to research published in the open access journal BMC Evolutionary Biology. The females' unreliable sexual swellings, which can remain swollen up to 31 days, make it difficult for a male to monopolize and guard female mates to ensure he sires their offspring. This may reduce aggressive mate competition and male sexual coercion toward females, and result in bono
- NASA researchers have found that several volcanic deposits on Mercury's surface require mantle melting to have started close to the planet's core-mantle boundary, which lies only 400km below the planets surface and making it unique in the solar system. This is reported at the Goldschmidt conference in Yokohama, Japan.
- An international team of scientists, led from Durham's Institute for Computational Cosmology (ICC), used new computer modelling of the Universe to investigate the colours that galaxies have and what those colours might tell us about how galaxies evolve.
- A study of how crystals moved in magma under the Mount Saint Helens volcano before the 1980 eruption may have signalled that an eruption was probable. Scientists say that similar measurements may indicate the possibility of eruption in some other, well-studied volcanoes, but caution that this is not a technique which could be applied to every volcano.
- Facebook has once again tweaked the formula it uses to decide what people will see in their news feed—and this time, it's personal.
- The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA's Dawn mission. The study, published online in the journal Nature, is one of two new papers about the makeup of Ceres.
- NASA's Juno spacecraft will make its long anticipated arrival at Jupiter on July 4. Coming face-to-face with the gas giant, Juno will begin to unravel some of the greatest mysteries surrounding our solar system's largest planet, including the origin of its massive magnetosphere.
- Large biomolecules in a small space spontaneously form symmetrical patterns. Researchers from FOM institute AMOLF discovered this together with colleagues from Oxford and Jülich when they confined rod-shaped virus particles in doughnut-shaped micro-chambers. What started as a chance discovery has opened up a whole new area in the physics of ultrasmall liquid crystal cells with potential applications in new displays. The results of the research will be published on June 29 2016, in Nature Co
- Scientists know that white sharks are important ocean predators, but many aspects of their lives are still a mystery. For example, each winter, large white sharks leave the California coast and swim halfway to Hawaii, congregating in an area known as the "White Shark Café." The males then repeatedly dive hundreds of feet below the surface. Researchers speculate that the sharks might be chasing prey or mating.
- Crucial new evidence has revealed modern humans (Homo sapiens) were likely using fire at Liang Bua 41,000 years ago, narrowing the time gap between the last hobbits (Homo floresiensis) and the first modern humans at this site on the Indonesian island of Flores.
- Tropical Cyclone 02A in the Arabian Sea east of Oman has been weakening and has become a tropical depression. The Global Precipitation Measurement or GPM mission core satellite analyzed the rainfall in the system.
- When a cell makes copies of DNA and translates its genetic code into proteins at the same time, the molecular machinery that carries on replication and the one that transcribes the DNA to the mRNA code move along the same DNA double strand as their respective processes take place. Sometimes replication and transcription proceed on the same direction, but sometimes the processes are in a collision course. Researchers at Baylor College of Medicine and the University of Wisconsin have determined th
- University of Montana researchers are giving the public its first look at the widespread use of herbicides on federal and tribal land in North America, and they urge land managers to better document it.
- In the face of climate change impact and inevitable sea level rise, Cornell and Scenic Hudson scientists studying New York's Hudson River estuary have forecast new intertidal wetlands, comprising perhaps 33 percent more wetland area by the year 2100.
- The long-lasting effects of El Niño are projected to cause an intense fire season in the Amazon, according to the 2016 seasonal fire forecast from scientists at NASA and the University of California, Irvine.
- Ammonia gas packs quite the smelly punch. In small doses, it's what makes smelling salts so effective. But high levels of ammonia can be a health hazard and a pollutant.
- With its extraordinary defensive hairs, a Colombian tarantula proved itself as not only a new species, but also a new genus. It is hypothesised that the new spider is the first in its subfamily to use its stinging hairs in direct attack instead of 'kicking' them into the enemy.
- Rochester Institute of Technology professors have developed a faster, more accurate way to assess gravitational wave signals and infer the astronomical sources that made them.
- A multinational team led by the Department of Energy's Oak Ridge National Laboratory Climate Change Science Institute has found the first positive correlation between human activity and enhanced vegetation growth.
- Anxiety over the Zika virus is growing as the Olympic Games in Rio de Janeiro approach. To better diagnose and track the disease, scientists are now reporting in ACS' journal Analytical Chemistry a new $2 test that in the lab can accurately detect low levels of the virus in saliva.
- The spread of cancer from a tumor's original location to other parts of the body can play a major role in whether the disease turns deadly. Many steps in this process, called metastasis, remain murky. But now scientists are gaining new insights into how cancer cells might squeeze through and even divide within narrow blood vessels while travelling in the body. They report their study using microtubular nanomembranes in the journal ACS Nano.

- Arizona State University says researchers have found pieces of a small asteroid that left a fiery trail in the sky over eastern Arizona earlier this month.
- World supplies of helium, the gas that makes your voice squeaky, may be on the ascent.

- Several conserved microRNAs, or short, highly conserved noncoding RNAs that are targeted to and inhibit expression of specific genes, may be involved in the regulation of limb regeneration across evolutionarily distant species, according to a study published June 29, 2016 in the open-access journal PLOS ONE by Benjamin King and Viravuth Yin from Mount Desert Island Biological Laboratory and the University of Maine.
Using highly sensitive isotope analysis, team obtained detailed measurements of carbon exchange in temperate forestFor the first time, scientists have been successful in measuring the processes by which an entire forest "breathes," using sophisticated technology involving flux towers and new instrumentation that can precisely measure two different types (isotopes) of carbon dioxide in the air. A team led by Richard Wehr and Scott Saleska at the University of Arizona obtained detailed long-term measurements of the respiration and photosynthesis rates of a temperate deciduous forest during the day and the nigh
