Global survey: Many teachers feel science curriculum is not relevant

The Hindu:Science - 14/07/2021
They advocate inter alia ‘rebalancing of exams’ — focus on assessing application

How to make biomedical research data able to interact?

Science Daily - 14/07/2021
Interoperability describes the ability of different systems to communicate. Scientists have now developed the strategy for a national infrastructure adopted by Swiss university hospitals and academic institutions. With its pragmatic approach, this strategy is based on the development of a common semantic framework that does not aim to replace existing standards, but to use them in a synergistic and flexible way according to the needs of the research and the partners involved.

New mechanism of superconductivity discovered in graphene

Science Daily - 14/07/2021
New mechanism of superconductivity discovered in graphene. Placing a 2D Bose-Einstein condensate in the vicinity of a graphene layer confers superconductivity to the material.

Conversion of genetic information from DNA to proteins: role of mRNA

Science Daily - 14/07/2021
mRNA plays a key role in the conversion of genetic information from DNA to proteins. Their production is a delicate process. A research team has now identified a crucial factor.

New evidence of an anomalous phase of matter brings energy-efficient technologies closer

Science Daily - 14/07/2021
Researchers have found evidence for an anomalous phase of matter that was predicted to exist in the 1960s. Harnessing its properties could pave the way to new technologies able to share information without energy losses.

Metal-based molecules show promise against the build-up of Alzheimer's peptides

Science Daily - 14/07/2021
In lab tests, researchers have created a metal-based molecule that inhibits the build-up of a peptide associated with Alzheimer's disease.

Personalized 3D printed knee implant could help thousands of arthritis sufferers

Science Daily - 14/07/2021
Pioneering 'printed metal' procedure to create bespoke treatment for early knee osteoarthritis set to be trialed in the UK following MHRA approval.

Study highlights need to replace 'ancestry' in forensics with something more accurate

Science Daily - 14/07/2021
A new study finds forensics researchers use terms related to ancestry and race in inconsistent ways, and calls for the discipline to adopt a new approach to better account for both the fluidity of populations and how historical events have shaped our skeletal characteristics.

Swarm of autonomous tiny drones can localize gas leaks

Science Daily - 14/07/2021
When there is a gas leak in a large building or at an industrial site, human firefighters currently need to go in with gas sensing instruments. Finding the gas leak may take considerable time, while they are risking their lives. Researchers have now developed the first swarm of tiny - and hence very safe - drones that can autonomously detect and localize gas sources in cluttered indoor environments.

Chemistry discovery could remove micropollutants from environment

Science Daily - 14/07/2021
New research identified a new chemistry approach that could remove micropollutants from the environment.

Idea sharing increases online learner engagement

Science Daily - 14/07/2021
Online learning engagement can be increased by nearly one-third by simply prompting students to share course ideas rather than personal details in the form of icebreakers and social introductions.

DNA from 1,600-year-old Iranian sheep mummy brings history to life

Science Daily - 14/07/2021
A team of geneticists and archaeologists has sequenced the DNA from a 1,600-year-old sheep mummy from an ancient Iranian salt mine, Chehrabad. This remarkable specimen has revealed sheep husbandry practices of the ancient Near East, as well as underlining how natural mummification can affect DNA degradation.

Signaling molecule may help prevent Alzheimer's disease

Science Daily - 14/07/2021
The main driver of Alzheimer's disease is excessive inflammation in the brain that is triggered by cells called astrocytes and microglia in response to high levels of amyloid beta deposits and tau tangles. New research reveals that a subset of astrocytes releases a molecule called interleukin-3 that instructs microglia to adopt a protective response and clear away amyloid beta deposits and tau tangles. Interleukin-3 may hold promise as a new therapeutic intervention in Alzheimer's disease.

Fungi that live in the gut influence health and disease

Science Daily - 14/07/2021
Bacteria's role in gut health has received attention in recent years. But new research shows that fungi -- another microorganism that lives within us -- may be equally important in health and disease. Fungi thrive in the healthy gut, but when interactions with the immune system are off-balance, they cause intestinal damage that may contribute to gastrointestinal disease. Additional investigation demonstrate that vaccines could be developed as therapeutics to improve gut health.

Hydrogel composite developed to help protective gear rapidly degrade toxic nerve agents

Science Daily - 14/07/2021
Scientists have developed a hydrogel integrated with zirconium-based robust metal-organic frameworks (MOFs) that rapidly degrades organophosphate-based nerve agents used in chemical warfare. Unlike existing powdered MOF adsorbents, this hydrogel composite does not require added water and may be easily scaled up for use in protective masks or clothing.

Antibiotics in early life could affect brain development

Science Daily - 14/07/2021
Antibiotic exposure early in life could alter human brain development in areas responsible for cognitive and emotional functions, according to researchers.

Opening the gate to the next generation of information processing

Science Daily - 14/07/2021
Scientists have devised a means of achieving improved information processing with a new technology for effective gate operation. This technology has applications in classical electronics as well as quantum computing, communications and sensing.

Study puts charge into drive for sustainable lithium production

Science Daily - 14/07/2021
A new study has yielded critical fresh insights into the lithium production process and how it relates to long-term environmental sustainability, particularly in the area of transportation with batteries and electric vehicles.

Business use of avatars

Science Daily - 14/07/2021
An associate professor of marketing says digital avatars can replace a sales force and customer service employees at a fraction of the cost.

Study reveals new aspects of gingivitis and body's response
