Giant sea lizard fossil shows diversity of life before asteroid hit

Science Daily - 12/05/2021
Scientists have identified the fossil of a giant mosasaur in Morocco that grew up to 8 meters long.

Smaller chips open door to new RFID applications

Science Daily - 12/05/2021
Researchers have made what is believed to be the smallest state-of-the-art RFID chip, which should drive down the cost of RFID tags. In addition, the chip's design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies.

An enzyme system for the hydrogen industry

Science Daily - 12/05/2021
An enzyme could make a dream come true for the energy industry: It can efficiently produce hydrogen using electricity and can also generate electricity from hydrogen. The enzyme is protected by embedding it in a polymer.

COVID-19: Discovery of the mechanisms of short- and long-term anosmia

Science Daily - 12/05/2021
Scientists have determined the mechanisms involved in the loss of smell in patients infected with SARS-CoV-2 at different stages of the disease. They discovered that SARS-CoV-2 infects sensory neurons and causes persistent epithelial and olfactory nervous system inflammation.

Organic meat less likely to be contaminated with multidrug-resistant bacteria

Science Daily - 12/05/2021
Meat that is certified organic by the U.S. Department of Agriculture is less likely to be contaminated with bacteria that can sicken people, including dangerous, multidrug-resistant organisms, compared to conventionally produced meat.

Best from science journals: Tiny injectable chips

The Hindu:Science - 12/05/2021
Here are some of the most interesting research papers to have appeared in top science journals last week.

Brand new physics of superconducting metals refuted by physicists

Science Daily - 12/05/2021
Scientists have demonstrated that other physicists' recent 'discovery' of the field effect in superconductors is nothing but hot electrons after all. A team of scientists have found new and compelling evidence that the observation of the field effect in superconducting metals by another group can be explained by a simple mechanism involving the injection of the electrons, without the need for novel physics.

Pandemic screen time tops 6 hours a day for some kindergartners

Science Daily - 12/05/2021
Kindergartners from low-income families spent more than six hours a day in front of screens during two early months of the COVID-19 pandemic, a small Ohio study suggests. That is nearly double the screen time found before the pandemic in similar children, according to other research.

Fatigue, mood disorders associated with post-COVID-19 syndrome

Science Daily - 12/05/2021
Patients diagnosed with post-COVID-19 syndrome, also known as 'PCS,' 'COVID-19 long-haul syndrome' and 'Post-Acute Sequelae of SARS COV-2,' experience symptoms such as mood disorders, fatigue and perceived cognitive impairment that can negatively affect returning to work and resuming normal activities, according to a new study.

Study of ancient corals in Indonesia reveals slowest earthquake ever recorded

Science Daily - 12/05/2021
A 'slow-motion' earthquake lasting 32 years - the slowest ever recorded - eventually led to the catastrophic 1861 Sumatra earthquake, researchers have found.

AI learns to type on a phone like humans

Science Daily - 12/05/2021
To really understand how people type on touchscreens, researchers have created the first artificial intelligence model that predicts how people move their eyes and fingers while typing. The AI model can simulate how a human user would type any sentence on any keyboard design. It makes errors, detects and corrects them, and also predicts how people adapt to a new auto-correction system or keyboard design.

Residential coal use in China results in many premature deaths, models indicate

Science Daily - 12/05/2021
Coal combustion by power plants and industry pollutes the air, causing many governments to implement mitigation actions and encourage cleaner forms of energy. Now, a new study indicates that in China, indoor air pollution from residential coal burning causes a disproportionate number of premature deaths from exposure to tiny, inhalable pollutants.

Earthworms could help reduce antibiotic resistance genes in soil

Science Daily - 12/05/2021
Earthworms improve the soil by aerating it, breaking down organic matter and mineralizing nutrients. Now, researchers have dug up another possible role: reducing the number and relative abundance of antibiotic-resistance genes (ARGs) in soils from diverse ecosystems. These results imply that earthworms could be a natural, sustainable solution to addressing the global issue of antibiotic resistance, the researchers say.

Gold leaf could help diagnose viral infections in low-resource settings

Science Daily - 12/05/2021
Gold leaf -- gold metal hammered into thin sheets -- is used by artists and crafters to gild picture frames, artwork and clothing. Despite its luxurious appearance, the material is affordable and available at most craft stores. Now, researchers have developed gold leaf electrodes that, in combination with a CRISPR-based assay, could sensitively detect human papillomavirus (HPV) DNA in human samples. The method also could be modified to diagnose other viral infections.

Harnessing the hum of fluorescent lights for more efficient computing

Science Daily - 12/05/2021
The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity.

Pink drinks can help you run faster and further, study finds

Science Daily - 12/05/2021
A new study shows that pink drinks can help to make you run faster and further compared to clear drinks.

Ancestors may have created 'iconic' sounds as bridge to first languages

Science Daily - 12/05/2021
The 'missing link' that helped our ancestors to begin communicating with each other through language may have been iconic sounds, rather than charades-like gestures -- giving rise to the unique human power to coin new words describing the world around us, a new study reveals.

Artificial intelligence tool uses chest X-ray to differentiate worst cases of COVID-19

Science Daily - 12/05/2021
Trained to see patterns by analyzing thousands of chest X-rays, a computer program predicted with up to 80 percent accuracy which COVID-19 patients would develop life-threatening complications.

Petting therapy dogs enhances thinking skills of stressed college students

Science Daily - 12/05/2021
Programs exclusively focused on petting therapy dogs improved stressed-out students' thinking and planning skills more effectively than programs that included traditional stress-management information, according to new research.

NASA's Voyager 1 detects the eerie hum of interstellar space

The Hindu:Science - 12/05/2021
The Voyager 1 spacecraft, launched in September 1977, is currently located about 22.7 billion km from Earth
