A simpler way to make some medicines Posted: 17 Oct 2019 11:36 AM PDT Organic chemists have figured out how to synthesize the most common molecule arrangement in medicine, a scientific discovery that could change the way a number of drugs -- including one most commonly used to treat ovarian cancer -- are produced. Their discovery, published today in the journal Chem, gives drug makers a crucial building block for creating medicines that, so far, are made with complex processes that result in a lot of waste. |
Blanket of light may give better quantum computers Posted: 17 Oct 2019 11:11 AM PDT Researchers describe how -- by simple means -- they have created a 'carpet' of thousands of quantum-mechanically entangled light pulses. The discovery has the potential to pave the way for more powerful quantum computers. |
Highest throughput 3D printer is the future of manufacturing Posted: 17 Oct 2019 11:10 AM PDT Researchers have developed a new, futuristic 3D printer that is so big and so fast it can print an object the size of an adult human in just a couple of hours. |
Weaving quantum processors out of laser light Posted: 17 Oct 2019 11:10 AM PDT Researchers open a new avenue to quantum computing with a breakthrough experiment: a large-scale quantum processor made entirely of light. |
Darn you, R2! When can we blame robots? Posted: 17 Oct 2019 09:52 AM PDT A recent study finds that people are likely to blame robots for workplace accidents, but only if they believe the robots are autonomous. |
Posted: 17 Oct 2019 09:19 AM PDT Engineers have found a way to significantly speed up the planning process required for a robot to adjust its grasp on an object by pushing that object against a stationary surface. Whereas traditional algorithms would require tens of minutes for planning out a sequence of motions, the new team's approach shaves this planning process down to less than a second. |
Double layer of graphene helps to control spin currents Posted: 17 Oct 2019 08:17 AM PDT In order to make transistors that operate using the spin of electrons, rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be equal to the time taken for these electrons to travel through a circuit. Scientists have now taken an important step forward by creating a device that meets both of these requirements. |
Physicists develop fast and sensitive mechanical tool to measure light Posted: 17 Oct 2019 08:17 AM PDT Physicists have developed a fast and sensitive mechanical tool to measure light. The graphene nanomechanical bolometer is the fastest and most sensitive in its class. It is poised to detect nearly every color of light at high speeds and obtain measurements at and far above room-temperature. |
First demonstration of one petabit per second network node Posted: 17 Oct 2019 08:17 AM PDT Computer scientists have demonstrated the first large-scale optical switching testbed capable of handling 1 Petabit per second optical signals. This demonstration made use of state-of-the-art large-scale and low-loss optical switches based on MEMS technology, three types of next-generation spatial-division multiplexing fibers, and included data rates from 10 Terabit per second to 1 Petabit per second. This is a major step forward towards practical petabit-class backbone networks. |
3D printed chocolate without temperature control Posted: 17 Oct 2019 07:12 AM PDT A new approach to the 3D printing of chocolate using cold extrusion instead of conventional hot-melt extrusion method eliminates the need for stringent temperature controls, offering wider potential for 3D printing temperature-sensitive food. |
Always on beat: Ultrashort flashes of light under optical control Posted: 17 Oct 2019 07:12 AM PDT Ultrashort laser pulses have enabled scientists and physicians to carry out high-precision material analyses and medical procedures. Physicists have now discovered a new method for adjusting the extremely short time intervals between laser flashes with exceptional speed and precision. The intervals can be increased or decreased as needed, all at the push of a button. Potential applications range from laser spectroscopy to microscopy and materials processing. |
Efficient synthesis of ginkgo compound could lead to new drugs, 'green' insecticides Posted: 17 Oct 2019 07:12 AM PDT Chemists have invented an efficient method for making a synthetic version of the plant compound bilobalide, which is naturally produced by gingko trees. It's a significant feat because bilobalide -- and closely related compounds -- hold potential commercial value as medicines and 'green' insecticides. |
Breaking water molecules apart to generate clean fuel: Investigating a promising material Posted: 17 Oct 2019 07:12 AM PDT Scientists investigated a material that uses sunlight for splitting water molecules (H2O) to obtain dihydrogen (H2). Since dihydrogen can be used as clean fuel, this study provides relevant insight for researchers dealing with clean energy generation. |
Digital breast tomosynthesis increases cancer detection over full-field mammography Posted: 16 Oct 2019 12:37 PM PDT A new article compares cancer detection rates (CDR) for screening digital breast tomosynthesis (DBT) versus full-field digital mammography (FFDM). Researchers found that DBT results in 'significantly increased CDR' -- irrespective of tumor type, size, or grade of cancer. |
New augmented reality system lets smartphone users get hands-on with virtual objects Posted: 16 Oct 2019 12:37 PM PDT A new augmented reality system places virtual objects within real-world backgrounds on cell phone screens and lets people interact with those object by hand as if they were really there. |
Recovering 'lost dimensions' of images and video Posted: 16 Oct 2019 12:36 PM PDT Researchers have developed a model that recovers valuable data lost from images and video that have been 'collapsed' into lower dimensions. |
Clingfish biology inspires better suction cup Posted: 16 Oct 2019 12:36 PM PDT A team of engineers and marine biologists built a better suction cup inspired by the mechanism that allows the clingfish to adhere to both smooth and rough surfaces. Researchers reverse engineered the clingfish's suction disk and developed devices that cling well to wet and dry objects both in an out of water. The devices can hold up to hundreds of times their own weight. |
Tiny particles lead to brighter clouds in the tropics Posted: 16 Oct 2019 10:12 AM PDT When clouds loft tropical air masses higher in the atmosphere, that air can carry up gases that form into tiny particles, starting a process that may end up brightening lower-level clouds, according to a new study. Clouds alter Earth's radiative balance, and ultimately climate, depending on how bright they are. The new paper describes a process that may occur over 40% of the Earth's surface. |
Putting the power of a film director in an autonomous drone Posted: 15 Oct 2019 11:02 AM PDT Commercial drone products can tackle some automated tasks, but one thing those systems don't address is filming artistically. Researchers have now proposed a complete system for aerial cinematography that learns humans' visual preferences. The fully autonomous system does not require scripted scenes, GPS tags to localize targets or prior maps of the environment. |
