Scientists use the Tokyo Skytree to test Einstein’s theory of general relativity

Posted: 09 Apr 2020 07:19 AM PDT

In another verification of the validity of Einstein’s theory of general relativity, published in Nature Photonics, scientists from the RIKEN Center for Advanced Photonics and Cluster for Pioneering Research, with colleagues, have used two finely tuned optical lattice clocks, one at the base and one on the 450-meter observatory floor of Tokyo Skytree, to make […]
How diet can change the way sugar tastes

Posted: 09 Apr 2020 07:15 AM PDT

The food animals eat can change how they perceive future food. This response uses the same machinery that the brain uses to learn, new research has found. The taste of sweetness is highly subjective.

Hormone produced in starved leaves stimulates roots to take up nitrogen

Posted: 09 Apr 2020 07:12 AM PDT

Nagoya University researchers have found that in response to the nitrogen demand of leaves, plants produce a hormone that travels from the leaves to the roots to stimulate the uptake of nitrogen from the soil. This hormone is produced in the leaves when they run short of nitrogen, and acts as a signal that regulates […]
Electromagnetic therapy effective for enlarged prostate

Posted: 09 Apr 2020 07:09 AM PDT

Physicians from Sapienza University in Rome have published promising results of a small prospective interventional trial using noninvasive pulsed electromagnetic field therapy (PEMF) to treat men suffering from benign prostatic hyperplasia (BPH). After one month of treatment, prostate volume and symptoms significantly decreased. Men with moderate-severe lower urinary tract symptoms and without metabolic syndrome benefitted […]
New ‘refrigerator’ super-cools molecules to nanokelvin temperatures

Posted: 09 Apr 2020 07:02 AM PDT

For years, scientists have looked for ways to cool molecules down to ultracold temperatures, at which point the molecules should slow to a crawl, allowing scientists to precisely control their quantum behavior. This could enable researchers to use molecules as complex bits for quantum computing, tuning individual molecules like tiny knobs to carry out multiple […]
Origins of Earth’s magnetic field remain a mystery

Posted: 09 Apr 2020 07:01 AM PDT

Microscopic minerals excavated from an ancient outcrop of Jack Hills, in Western Australia, have been the subject of intense geological study, as they seem to bear traces of the Earth’s magnetic field reaching as far back as 4.2 billion years ago. That’s almost 1 billion years earlier than when the magnetic field was previously thought […]
Bluetooth signals from your smartphone could automate Covid-19 contact tracing while preserving privacy

Posted: 09 Apr 2020 07:00 AM PDT

Imagine you’ve been diagnosed as Covid-19 positive. Health officials begin contact tracing to contain infections, asking you to identify people with whom you’ve been in close contact. The obvious people come to mind — your family, your coworkers. But what about the woman ahead of you in line last week at the pharmacy, or the […]
Animals and COVID-19

Posted: 08 Apr 2020 09:18 AM PDT

Since the start of the COVID-19 pandemic, animals have been very present in the media. The reason being that they play an essential role in our world, most often this goes unnoticed but in tough times importance of animals becomes more visible. A few examples, animals have been related to the very origin of the disease, […]
