Aquatic robots can remove contaminant particles from water

Eurekalert.org 

Scientists from WMG at the University of Warwick, led by Eindhoven University of Technology in the Netherlands, developed a 1cm by 1cm wireless artificial aquatic polyp, which can remove contaminants from water. Apart from cleaning, this soft robot could be also used in medical diagnostic devices by aiding in picking up and transporting specific cells for analysis.

New global study shows 'best of the last' tropical forests urgently need protection

Eurekalert.org 

The world's 'best of the last' tropical forests are at significant risk of being lost, according to a paper released today in Nature Ecology and Evolution. Of these pristine forests that provide key services--including carbon storage, prevention of disease transmission and water provision--only a mere 6.5 percent are formally protected.

Army advances learning capabilities of drone swarms

Eurekalert.org 

Army researchers developed a reinforcement learning approach that will allow swarms of unmanned aerial and ground vehicles to optimally accomplish various missions while minimizing performance uncertainty.

AI-enhanced precision medicine identifies novel autism subtype

Eurekalert.org 

A novel precision medicine approach enhanced by artificial intelligence has laid the groundwork for what could be the first biomedical screening and intervention tool for a subtype of autism, reports a new study. The approach is believed to be the first of its kind. Today, autism is diagnosed based only on symptoms and by the time a physician identifies it, it's often when early and critical brain developmental windows have passed without appropriate intervention. This discovery could shift that paradigm.



Countering anti-vaccination influences from social media - with conversation

Eurekalert.org 

What effect, if any, do anti-vaccination social media messages have on actual vaccination behavior? A new study using big data and survey results from the 2018-19 flu season finds strong associations between regional social media messages and vaccination attitudes and behavior. But when there are negative associations between social media content and vaccination, real-life discussions with family and friends appear to eliminate them.

NIST's SAMURAI measures 5G communications channels precisely

Eurekalert.org 

Engineers at the National Institute of Standards and Technology (NIST) have developed a flexible, portable measurement system to support design and repeatable laboratory testing of fifth-generation (5G) wireless communications devices with unprecedented accuracy across a wide range of signal frequencies and scenarios.

Detailed molecular workings of a key system in learning and memory formation

Eurekalert.org 

UMass Amherst biochemist Margaret Strattob and colleagues report how they used advanced sequencing technology to clear up uncertainty and determine all variants of a single protein/enzyme known as calcium/calmodulin-dependent protein kinase II (CaMKII) in the hippocampus, the brain's memory center.

Retesting for COVID-19: UPMC shares its experience

Eurekalert.org 

In the first large, multicenter analysis of its kind, the 40-hospital UPMC health system today reported its findings on clinician-directed retesting of patients for presence of SARS-CoV-2, the virus that causes COVID-19, in the journal Infection Control & Hospital Epidemiology. While retesting was uncommon, the UPMC analysis found that patients positive for COVID-19 stayed positive for an average of three weeks and repeating tests in patients who were initially negative very rarely led to a positive result.

New USask-led research reveals previously hidden features of plant genomes

Eurekalert.org 

An international team led by the Plant Phenotyping and Imaging Research Centre (P2IRC) at the University of Saskatchewan (USask) and researchers at Agriculture and Agri-Food Canada (AAFC) has decoded the full genome for the black mustard plant--research that will advance breeding of oilseed mustard crops and provides a foundation for improved breeding of wheat, canola and lentils.

Breaking molecular traffic jams with finned nanoporous materials

Eurekalert.org 

Researchers at the University of Houston are reporting the invention of a new class of porous catalysts that will speed up reactions, breaking the molecular traffic jam that can slow them down. The discovery has immediate relevance to industry for a host of applications, including the production of fuels, chemicals for plastics and polymers, and reactions that make molecules for food, medicine and personal care products.

NASA finds strong storms in developing Tropical Storm Mekkhala

Eurekalert.org 

After Tropical Depression 07W formed close to the western Philippines, it moved away and strengthened into a tropical storm in the South China Sea. NASA's Terra satellite provided a look at the strength of the storms that make up the tropical cyclone.

HPV strains may impact cervical cancer prognosis

Eurekalert.org 

An analysis of cervical cancers in Ugandan women has uncovered significant genomic differences between tumours caused by different strains of human papillomavirus (HPV), signifying HPV type may impact cervical cancer characteristics and prognosis.

Stronger rains in warmer climate could lessen heat damage to crops, says study

Eurekalert.org 

Intensified rainstorms predicted for many parts of the United States as a result of warming climate may have a modest silver lining: they could more efficiently water some major crops, and this would at least partially offset the far larger projected yield declines caused by the rising heat itself.
