New machine learning algorithm uncovers time-delayed interactions in cells

Mon, 02/12/2018 - 21:09
A new algorithm uses time-series data to show the cause-and-effect interactions that take place inside of living cells.

New method for waking up devices

Mon, 02/12/2018 - 20:07
A device that's turned off doesn't suck battery life, but it also doesn't work. Now a low-power system that's always on the alert can turn devices on when they are needed, saving energy in the networked internet of things.

Study finds gender and skin-type bias in commercial artificial-intelligence systems

Mon, 02/12/2018 - 17:12
A new article shows that three commercial facial-analysis programs demonstrate gender and skin-type biases, and suggests a new, more accurate method for evaluating the performance of such machine-learning systems.

Scalable two-dimensional materials advance future-gen electronics

Mon, 02/12/2018 - 17:10
A pair of papers published online in two nanotechnology journals this month provide the basis for growing wafer-scale two-dimensional crystals for future electronic devices

Cancer-fighting nanorobots programmed to seek and destroy tumors

Mon, 02/12/2018 - 16:20
In a major advancement in nanomedicine, scientists have successfully programmed nanorobots to shrink tumors by cutting off their blood supply.

New process allows 3-D printing of nanoscale metal structures

Mon, 02/12/2018 - 15:06
By mixing metal ions and organic ligands, scientists have developed a process for the 3-D printing of metal structures that are smaller than ever before.

The Scanpy software processes huge amounts of single-cell data

Mon, 02/12/2018 - 13:52
Scientists have developed a program that is able to help manage enormous datasets. The software, named Scanpy, is a candidate for analyzing the Human Cell Atlas.

Web-based teaching can improve science understanding for struggling pupils

Mon, 02/12/2018 - 13:45
Web-based learning tools can help deepen science knowledge among all middle school students, and ease the science literacy gap for underachieving students, according to a three-year study.

Forging a quantum leap in quantum communication

Fri, 02/09/2018 - 16:23
The major drawback of quantum communication today is the slow speed of data transfer, which is limited by the speed at which the parties can perform quantum measurements. Researchers have now devised a method that overcomes this.

Your gadget's next power supply? Your body

Fri, 02/09/2018 - 16:23
Searching for a power outlet may soon become a thing of the past. Instead, devices will receive electricity from a small metallic tab that, when attached to the body, is capable of generating electricity from bending a finger and other simple movements.

Mass production of new class of semiconductors closer to reality

Fri, 02/09/2018 - 15:07
Chemists have made it easier for manufacturers to produce a new class of faster and cheaper semiconductors.

AI computer vision breakthrough IDs poachers in less than half a second

Thu, 02/08/2018 - 23:03
Researchers have long been applying AI to protect wildlife. Initially, computer scientists were using AI and game theory to anticipate the poachers' haunts, and now they have applied artificial intelligence and deep learning to spot poachers in near real-time.

New '4-D goggles' allow wearers to be 'touched' by approaching objects

Thu, 02/08/2018 - 21:19
A team of researchers has developed a pair of '4-D goggles' that allows wearers to be physically 'touched' by a movie when they see a looming object on the screen, such as an approaching spacecraft.

Earthquake simulations of California's Hayward fault

Thu, 02/08/2018 - 19:51
In the next 30 years, there is a one-in-three chance that California's Hayward fault will rupture with a 6.7 magnitude or higher earthquake. Scientists have used some of the world's most powerful supercomputers to model ground shaking for a magnitude 7.0 earthquake on the Hayward fault and show more realistic motions than ever before.

3-D vision discovered in praying mantis

Thu, 02/08/2018 - 17:09
Miniature glasses have revealed a new form of 3-D vision in praying mantises that could lead to simpler visual processing for robots.

The beneficial aspects of mindfulness for students of computer engineering

Thu, 02/08/2018 - 17:08
Subjected to the same practice exercise, the group of students that participated in mindfulness sessions obtained better results than those that did not take part in this activity.

How good a match is it? Putting statistics into forensic firearm identification

Thu, 02/08/2018 - 17:08
When comparing bullets or cartridge cases, a forensic firearms examiner can offer an expert opinion as to whether or not they match. But they cannot express the strength of the evidence numerically, the way a DNA expert can when testifying about genetic evidence. Now, researchers have developed a statistical approach for ballistic comparisons that may enable numerical testimony. 

Researchers help robots 'think' and plan in the abstract

Thu, 02/08/2018 - 17:08
New research shows how robots can autonomously construct abstract representations of their surroundings and use them to plan for multi-step tasks.

'Smart thermometer' improves flu forecasting

Thu, 02/08/2018 - 17:08
A new approach shows that de-identified data from a 'smart thermometer' connected to a mobile phone app can track flu activity in real time at both population and individual levels and the data can be used to significantly improve flu forecasting.

Bitcoin crash could derail other cryptocurrencies

Thu, 02/08/2018 - 15:43
A sharp fall in the value of Bitcoin may cause other cryptocurrencies to crash, but is unlikely to have a significant impact on traditional assets, according to new research.
