New method for probing the bewildering diversity of the microbiome

Posted: 04 Apr 2022 03:55 PM PDT

Scientists describe a new method for probing the microbiome in unprecedented detail. The technique provides greater simplicity and ease of use compared with existing approaches. Using the new technique, the researchers demonstrate an improved ability to pinpoint biologically relevant characteristics, including a subject's age and sex based on microbiome samples.

Disbelief in human evolution linked to greater prejudice and racism

A disbelief in human evolution was associated with higher levels of prejudice, racist attitudes and support of discriminatory behavior against Blacks, immigrants and the LGBTQ community in the U.S., according to recent research.

The secret to better coffee? The birds and the bees

Posted: 04 Apr 2022 12:27 PM PDT

A groundbreaking study reveals that without birds and bees working together, some traveling thousands of miles, coffee farmers would see a whopping 25% drop in crop yields. Coffee is bigger and more plentiful when birds and bees team up to protect and pollinate coffee plants. The study is also the first to show, with real-world experiments, that the contributions of nature -- ie. from bees and birds -- are larger combined than their individual contributions. This suggests researchers may be underestimating how much the environment benefits society.

Alternate delivery locations are viable options to offset negative impacts of increased home deliveries

Posted: 04 Apr 2022 12:01 PM PDT

As the demand for home deliveries from online purchases continues to increase, researchers recently published research showing that some -- but not all -- consumers will accept going to alternate delivery locations to get their packages rather than having them delivered directly to their front door.

Solar hydrogen: Better photoelectrodes through flash heating

Posted: 04 Apr 2022 09:05 AM PDT

Producing low-cost metal-oxide thin films with high electronic quality for solar water splitting is not an easy task. Especially since quality improvements of the upper metal oxide thin films need thermal processing at high temperatures, which would melt the underlying glass substrate. Now, a team has solved this dilemma: A high intensity and rapid light pulse directly heats the semiconducting metal-oxide thin film, allowing it to reach the optimal temperature without damaging the substrate.

Cutting palm trees to harvest fruit? Better to let trees grow

Posted: 04 Apr 2022 09:05 AM PDT

Scientists have shown for the first time the widespread harm caused in Peru by cutting down the palm tree Mauritia flexuosa in order to harvest its fruit. The scientists examined where and why the trees were felled, producing detailed maps and analysis to reveal the extent of the environmental and economic damage caused by cutting down the palms.

T. rex's short arms may have lowered risk of bites during feeding frenzies

Posted: 01 Apr 2022 06:48 AM PDT

Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility. While scientists have suggested explanations, a paleontologist puts the proposals to the test and finds them wanting. He hypothesizes that the arms reduced in size to limit damage, possibly fatal, when a pack of T. rexes descended on a carcass with their bone-crunching teeth.
