Federal research funding has positive 'ripple effects'

Posted: 22 Apr 2022 01:15 PM PDT

Federal funding for biomedical research has a 'ripple effect' of stimulating new studies even beyond the original purposes of a grant and may provide unexpected benefits, a new study suggests.

Making 3D printing truly 3D: eliminating need for 2D layering

Posted: 22 Apr 2022 01:15 PM PDT

Researchers describe a technique of volumetric 3D printing that goes beyond the bottom-up, layered approach. The process eliminates the need for support structures because the resin it creates is self-supporting.

A roadmap for deepening understanding of a puzzling universal process

Posted: 22 Apr 2022 10:18 AM PDT

Scientists have detailed a roadmap for untangling a key aspect of magnetic recognition that could deepen insight into the workings of the cosmos.

Scientists turn a hydrogen molecule into a quantum sensor

Posted: 22 Apr 2022 10:18 AM PDT

Using a scanning tunneling microscope equipped with a femtosecond terahertz laser, scientists have exploited the quantum properties of a two-atom hydrogen molecule to observe changes in the electrostatic field of a target sample, turning the hydrogen molecule into a quantum sensor.

The physics of a singing saw

Posted: 22 Apr 2022 08:47 AM PDT

Researchers have used the singing saw to demonstrate how the geometry of a curved sheet, like curved metal, could be tuned to create high-quality, long-lasting oscillations for applications in sensing, nanoelectronics, photonics and more.

Flexible electronics get brighter

Posted: 22 Apr 2022 06:43 AM PDT

Scientists have fabricated a flexible material that lights up brightly when stretched and/or when an electric field is applied. The results show promise for the development of bright, sustainable, stretchable devices for use, for example, as interactive skin displays and in soft robotics.

New self-cleaning optical fiber can help in monitoring environment and diagnosing cancer

Posted: 22 Apr 2022 06:43 AM PDT

Researchers have successfully developed a novel optical fiber design allowing the generation of rainbow laser light in the molecular fingerprint electromagnetic region. This new optical fiber with a self-cleaned beam can help in developing applications to, for example, tagging pollutants, cancer diagnostics, environmental monitoring, and food control.

Water processing: Light helps degrade hormones

Posted: 22 Apr 2022 06:43 AM PDT

Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers have now developed a process for the photocatalytic degradation of these pollutants when they flow through polymer membranes. Irradiation with light triggers a chemical reaction, as a result of which steroid hormones are degraded on the membranes coated with titanium dioxide.

Artificial intelligence helps physicians better assess the effectiveness of bladder cancer treatment

Posted: 22 Apr 2022 06:43 AM PDT

In a small but multi-institutional study, an artificial intelligence-based system improved providers' assessments of whether patients with bladder cancer had complete response to chemotherapy before a radical cystectomy (bladder removal surgery).

Atomic terahertz-vibrations solve the enigma of ultrashort soliton molecules

Posted: 22 Apr 2022 06:43 AM PDT

Optical solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers have solved the puzzle of how these temporal links are formed.

This algorithm has opinions about your face

Posted: 21 Apr 2022 03:12 PM PDT

Researchers have now taught an AI algorithm to model first impressions and accurately predict how people will be perceived based on a photograph of their face.

Machine-learning model can distinguish antibody targets

Posted: 21 Apr 2022 12:41 PM PDT

A new study shows that it is possible to use the genetic sequences of a person's antibodies to predict what pathogens those antibodies will target. The new approach successfully differentiates between antibodies against influenza and those attacking SARS-CoV-2, the virus that causes COVID-19.

Revolutionary images of the birth of crystals

Posted: 21 Apr 2022 11:16 AM PDT

Scientists have succeeded in visualizing crystal nucleation -- the stage that precedes crystallization -- that was invisible until now.
