Light-based production of drug-discovery molecules
Posted on Monday February 18, 2019

Chemists have developed a light-based chemical method for cheap and simple production of chemical molecules used in drug discovery, such as muscle relaxants and antimicrobials.

Gearing up for 5G: A miniature, low-cost transceiver for fast, reliable communications
Posted on Monday February 18, 2019

Researchers have designed a 28 GHz transceiver that integrates beamforming with dual-polarized multiple-input and multiple-output (MIMO) technology. Measuring just 3 mm by 4 mm, this tiny transceiver could help improve performances of fifth-generation cellular network (5G) and Internet of Things (IoT) devices.

Weak spots for Mission to Mars revealed
Posted on Sunday February 17, 2019

Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and head off problems that could make or break the Mission to Mars.

Altered data sets can still provide statistical integrity and preserve privacy
Posted on Sunday February 17, 2019

Synthetic networks may increase the availability of some data while still protecting individual or institutional privacy, according to a statistician.

Engineered metasurfaces reflect waves in unusual directions
Posted on Saturday February 16, 2019

Researchers have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking classical reflection law to engineer it at will.

How do we conserve and restore computer-based art in a changing technological environment?
Posted on Saturday February 16, 2019

Just as conservators have developed methods to protect traditional artworks, computer scientists have now created means to safeguard computer- or time-based art by following the same preservation principles.

Graphene-based wearables for health monitoring, food inspection and night vision
Posted on Saturday February 16, 2019

Scientists have developed dozens of new graphene-based prototypes. These technologies aim to turn mobile phones into life saving devices.

Lithium-air batteries can store energy for cars, houses and industry
Posted on Friday February 15, 2019

Growth in the offer of renewable energy sources will mean increased demand for devices optimal for energy storing.

Can we trust scientific discoveries made using machine learning?
Posted on Friday February 15, 2019

Statisticians are cautioning fellow scientists not to make assumptions about the accuracy, uncertainty or reproducibility of scientific discoveries made with today's machine learning models.

Tidal tails: The beginning of the end of an open star cluster
Posted on Friday February 15, 2019

In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system. In open clusters, this phenomenon existed only in theory. Researchers have now finally verified the existence of such a tidal tail in the star cluster closest to the Sun, the Hyades. An analysis of measurements from the Gaia satellite led to the discovery.

Solid-state catalysis: Fluctuations clear the way
Posted on Friday February 15, 2019

Chemists have identified a mechanism that allows molecules to diffuse rapidly on the already crowded surface of a solid-state catalyst - an important capability, especially for efficient catalysis under industrial conditions.

Researchers discover anti-laser masquerading as perfect absorber
Posted on Friday February 15, 2019

Researchers have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of 'time-reversed laser' known as a coherent perfect absorber (CPA).

A nearby river of stars
Posted on Friday February 15, 2019

Astronomers have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.

Artificial intelligence can predict survival of ovarian cancer patients
Posted on Friday February 15, 2019

Researchers have created new machine learning software that can forecast the survival rates and response to treatments of patients with ovarian cancer.

Immersive virtual reality therapy shows lasting effect in treatment of phobias in children with autism
Posted on Friday February 15, 2019

New research shows that an immersive virtual reality environment treats 45 percent of children with autism, freeing them from their fears and phobias -- and that the treatment lasts.

Improved RNA data visualization method gets to the bigger picture faster
Posted on Thursday February 14, 2019

Like going from a pinhole camera to a Polaroid, a significant mathematical update to the formula for a popular bioinformatics data visualization method will allow researchers to develop snapshots of single-cell gene expression not only several times faster but also at much higher-resolution. This innovation by mathematicians will reduce the rendering time of a million-point single-cell RNA-sequencing (scRNA-seq) data set from over three hours down to just fifteen minutes.

Better red than dread: Barrier keeps batteries safe
Posted on Thursday February 14, 2019

A layer of red phosphorus in rechargeable lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. The strategy, which does not require a third electrode, could help bring more powerful lithium metal batteries to market.

Spintronics by 'straintronics'
Posted on Thursday February 14, 2019

Data storage in magnetic media is very energy consuming. Novel materials could reduce the energy needed to control magnetic memories thus contributing to a smaller carbon footprint of the IT sector. Now an international team has observed at the HZB lightsource BESSY II a new phenomenon in iron nanograins: whereas normally the magnetic moments of the iron grains are disordered at room temperature, this can be changed by applying an electric field.

Multitasking increases in online courses compared to face-to-face
Posted on Thursday February 14, 2019

The phenomenon of multitasking across three or four internet-connected devices simultaneously is increasingly common. Researchers were curious to know how often this happens during online education, a method of delivering college and even high school courses entirely via an internet-connected computer as opposed to a traditional face-to-face course with a teacher physically present.

Shaping light lets 2D microscopes capture 4D data
Posted on Thursday February 14, 2019

Researchers have created a method to design custom masks that transform 2D fluorescent microscopy images into 3D movies.
