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 […]

- Planets are thought to form in the disks of dust and gas found around young stars. But astronomers have struggled to assemble a complete theory of their origin that explains how the initial dust develops into planetary systems. A French-UK-Australian team now think they have the answer, with their simulations showing the formation of 'dust traps' where pebble-sized fragments collect and stick together, to grow into the building blocks of planets. They publish their results in Monthly Notices of
- When a storm puts a tree branch through your roof, or a flood damages your foundation, you turn to your insurance company to pay for the repairs. And when it's only one, or two, or even 10 claims, insurance can cover the costs, no problem. But when it's an entire city? An entire state? The price of paying all of those claims at once can sometimes be enough to not only bankrupt the company, but to collapse the economy of an entire region.
- Most strategies to combat climate change concentrate on reducing greenhouse gas emissions by substituting non-carbon energy sources for fossil fuels, but a task force commissioned in June 2016 by former U.S. Secretary of Energy Ernest Moniz proposed a framework in December 2016 for evaluating research and development on two additional strategies: recycling carbon dioxide and removing large amounts of carbon dioxide from the atmosphere. These strategies were developed under a single framework wit
- AT&T's $85 billion purchase of Time Warner may be getting an easier path to approval after the chief telecommunications regulator says it isn't likely to review the deal.
- SpaceX says it will fly two people to the moon next year.
- A new federal study shows less pollution in most New Jersey streams, but salt levels rising in some places.
- When the universe was young, a supermassive black hole—bloated to the bursting point with stupendous power—heaved out a jet of particle-infused energy that raced through the vastness of space at nearly the speed of light.
- Fossil hunters have found part of an ancient primate jawbone related to lemurs—the primitive primate group distantly connected to monkeys, apes and humans, a USC researcher said.
- Pulling data from 180 different lines of fruit flies, researchers from Michigan Technological University compared resistance to a toxin found in mushrooms like the Death Cap and Destroying Angel. Their results were published by PLOS ONE this week.
- New light on a key factor involved in diseases such as Parkinson's disease, gastric cancer and melanoma has been cast through latest University of Otago, New Zealand, research carried out in collaboration with Australian scientists.
- The iron-containing molecule heme is necessary for life. Cells require heme to perform the chemical reactions that produce energy, among other critical tasks.
- A University of Central Florida professor has invented a way to use light to continuously monitor a surgical patient's blood, for the first time providing a real-time status during life-and-death operations.
- As the world warms, mountain snowpack will not only melt earlier, it will also melt more slowly, according to a new study by scientists at the National Center for Atmospheric Research (NCAR).
- Millennials pursuing careers in public relations don't feel ready to give advice on moral dilemmas to their companies. In fact, they don't expect to face ethical dilemmas at work, according to a Baylor University study.
- Most dog owners will tell you they consider their beloved pets to be members of their families. Now new research suggests that dogs may be even more like us than previously thought.
- "What's in a name? That which we call a rose by any other name would smell as sweet." This phrase—from William Shakespeare's tragic play Romeo & Juliet—is among the most famous acknowledgements in Western culture of the power of naming to shape human perception.
- An invasive species of marsh grass that spreads, kudzu-like, throughout North American wetlands, may provide similar benefits to protected wetlands as native marsh grasses. According to new research from North Carolina State University, the invasive marsh grass's effects on carbon storage, erosion prevention and plant diversity in protected wetlands are neutral. The findings could impact management strategies aimed at eradicating the invasive grass.
- Hunting for habitable exoplanets now may be easier: Cornell University astronomers report that hydrogen pouring from volcanic sources on planets throughout the universe could improve the chances of locating life in the cosmos.
- Rice University researchers have modeled a nanoscale sandwich, the first in what they hope will become a molecular deli for materials scientists.
- If you build it, they will come. That's historically been a common approach to species recovery: Grow the prey population first and predators will quickly return. As it turns out, that's not quite the case. A new study has found that restoring predator and prey species simultaneously speeds the recovery efforts of both.
- Ocean acidification (OA) is spreading rapidly in the western Arctic Ocean in both area and depth, according to new interdisciplinary research reported in Nature Climate Change by a team of international collaborators, including University of Delaware professor Wei-Jun Cai.
- As spacecraft become larger, the heat they produce also increases. That means vehicles built for long-term space exploration need more efficient cooling systems.
- Humans have dramatically increased the spatial and seasonal extent of wildfires across the U.S. in recent decades and ignited more than 840,000 blazes in the spring, fall and winter seasons over a 21-year period, according to new research.
A rose to store energy: In vivo polymerization and manufacturing of wires and supercapacitors in plantsA special structure for storing energy known as a supercapacitor has been constructed in a plant for the first time. The plant, a rose, can be charged and discharged hundreds of times. This breakthrough is the result of research at the Laboratory of Organic Electronics at Linköping University.
- Mobile apps designed to keep teens safe online are overwhelmingly focused on parental control, which may be only a short-term solution that hinders a teen's ability to learn coping strategies in the long run, according to a team of researchers.
- A Washington State University research team has improved an important catalytic reaction commonly used in the oil and gas industries. The innovation could lead to dramatic energy savings and reduced pollution.
- On the surfaces of our trillions of cells is a complex crowd of molecules moving around, talking to each other, occasionally segregating themselves, and triggering basic functions ranging from pain sensation to insulin release.
- While smartphones get top billing at the Mobile World Congress in Barcelona, Spain, it's the quirky, under-the-radar products that are getting a lot of the visitors' attention.
- For many of us spring cleaning is an annual ritual and it will be here before we know it. Imagine trying to keep everything organized year-round in a five-bedroom house where everything floats. And that house is moving 17,500 miles per hour orbiting the Earth 250 miles above us. That's exactly the job of a small team at the Marshall Space Flight Center in Huntsville, Alabama.
