A new sort of optical device allows engineers to change the frequencies of individual photons, putting new capabilities in engineers' hands.

Researchers from Osaka University and JOANNEUM RESEARCH develop ultrathin piezoelectric flexible patches that harvest the body's energy to monitor the patient's pulse and blood pressure. This work may lead to novel biosensors and self-powered wearable electronics.

When a patient with chest pain arrives at hospital, time is of the essence. Doctors must quickly rule heart attack in or out and start treatment as soon as possible. A new study reveals blood biomarkers that could help. By analyzing blood samples from patients with chest pain, researchers found a unique fingerprint of heart attack in the form of blood biomarkers. The results could help doctors to quickly diagnose and treat heart attack patients.

The distance between the product and the consumer, whether in real life or in ads, can have a profound influence on how consumers evaluate the product and make purchase decisions.

New research led by Curtin University has revealed how radar satellites can improve the ability to detect, monitor, prepare for and withstand natural disasters in Australia including bushfires, floods and earthquakes.

* High-level vaccine efficacy of 77% in African children achieve WHO-specified efficacy goal of 75%* Vaccine, trialled in 450 children, shows favourable safety profile and was well-tolerated* Vaccine candidate, R21/Matrix-M, has excellent potential for large-scale manufacturing and low-cost supply

New research provides evidence that people have transmitted SARS-CoV-2, the virus that causes COVID-19, to cats during the pandemic in the UK. The study, which is published in Veterinary Record, detected the virus last year in cats that developed mild or severe respiratory disease.

Over the last 60 years, scientists have been able to observe how and when genetic information was replicated, determining the existence a "replication timing program", a process that controls when and in what order segments of DNA replicate. However, scientists still cannot explain why such a specific timing sequence exists. In a study published today in Science, Dr. David Gilbert and his team have answered this 60-year-old question.

In lab tests, researchers found that an optimized ankle exoskeleton system increased participants' walking speed by about 40 percent compared with their regular speed. The researchers hope someday to help restore walking speed in older adults.

Attempts at restricting people's mobility to control the spread of COVID-19 may be effective only for a short period, researchers said. A new study examines people's mobility for seven months during the pandemic in the United States using publicly available, anonymized mobile phone data.

Melting glaciers redistributed enough water to cause the direction of polar wander to turn and accelerate eastward during the mid-1990s, according to a new study in AGU's Geophysical Research Letters.

To look inside a stalagmite is to look back in time tens of thousands of years to see how the Earth's climate patterns have shaped the world we live in today.

A joint research study by the Pacific Water Research Centre at Simon Fraser University and the Fraser Basin Council points to the use of certified, nature-based solutions for protecting salmon and aquatic habitats in the Lower Mainland.

Based on the extended Baryon Oscillation Spectroscopic Survey (eBOSS) observations, scientists from the National Astronomical Observatories of the Chinese Academy of Sciences make a further step towards understanding dark energy.

A new research paper examining the relationship between the Omega-3 Index and risk for death from any and all causes has been published in Nature Communications. It showed that those people with higher omega-3 EPA and DHA blood levels (i.e., Omega-3 Index) lived longer than those with lower levels. In other words, those people who died with relatively low omega-3 levels died prematurely, i.e., all else being equal, they might have lived longer had their levels been higher.

A group of scientists from Gladstone Institutes, the Center for iPS Cell Research and Application (CiRA) from Kyoto University, and the RIKEN Center for Biosystems Dynamics Research in Kobe, Japan, has now demonstrated the presence of precursors of the placenta and the amniotic sac in synthetic embryos they created from mouse stem cells.

The results of the Phase I NRG-BR001 trial, conducted by the NCI National Clinical Trials Network group NRG Oncology, indicate that stereotactic body radiotherapy (SBRT) treatment in standard doses was safe for 35 evaluable patients with a median of 3 metastases. There were no dose-limiting toxicities and over 50% of trial participants were alive at 2 years following treatment.

A new imaging technique that can capture movies of individual receptors on the surface of living cells in unprecedented detail could pave the way to a trove of new drugs.

An unusual belt of igneous rocks stretches for over 2,000 miles from British Columbia, Canada, to Sonora, Mexico, running through Idaho, Montana, Nevada, southeast California and Arizona.

A new species of deep-sea dwelling dumbo octopus called Grimpoteuthis imperator sp. nov. has been described using a combination of MRI, micro-CT and minimally invasive gene analysis rather than traditional dissection methods. The findings are presented in the open access journal BMC Biology.
