Sloths the slowest digestive system of any animal on Earth. It can take the mammals two weeks to digest an entire meal, and they sleep about 20 hours a day to conserve energy. Deposit PhotosThese cryptic critters use lack of activity to their advantage. The post Sloth schedules are surprisingly...

68 percent of Americans assume any product with the resin code and recycling symbol is recyclable. DepositPhotosThe recognizable chasing arrows icon could be doing more harm than good—so the EPA wants to toss it. The post Why the recycling symbol is part of a ‘misinformation campaign’ appeared first on Popular...

Tesla plans to open its charging stations to other electric vehicles. TeslaMustang Mach-E, F-150 Lightning and E-Transit customers can start using adapters to plug into superchargers. The post Ford EVs can soon be charged at Tesla stations appeared first on Popular Science....

Recent research sheds light on how the brain processes and interprets dynamic environmental signals. New understandings have been gleaned by scientists about the region of......

Kelps provide food and habitat for myriad coastal creatures. DepositPhotosIn Washington State, the Jamestown S’Klallam Tribe’s new preservation facility offers a back-up plan for an uncertain future. The post Scientists and indigenous people team up to build a kelp seed bank appeared first on Popular Science....

This paper is on the automated driving architecture and operation of a light commercial vehicle. Simple longitudinal and lateral dynamic models of the vehicle and a more detailed CarSim model are developed and used in simulations and controller design and evaluation. Experimental validation is used to make sure that the...

The rich chemical information from tissue metabolomics provides a powerful means to elaborate tissue physiology or tumor characteristics at cellular and tumor microenvironment levels. However, the process of obtaining such information requires invasive biopsies, is costly, and can delay clinical patient management. Conversely, computed tomography (CT) is a clinical standard...

Providing rich and useful information regarding spectrum activities and propagation channels, radiomaps characterize the detailed distribution of power spectral density (PSD) and are important tools for network planning in modern wireless systems. Generally, radiomaps are constructed from radio strength measurements by deployed sensors and user devices. However, not all areas...

An important topic in medical research is the process of improving the images obtained from medical devices. As a consequence, there is also a need to improve medical image resolution and analysis. Another issue in this field is the large amount of stored medical data [16]. Human brain databases at...

Background: Schwann cells (SCs) are glial cells involved in peripheral axon myelination. SCs also play a strategic role after peripheral nerve injury, regulating local inflammation and axon regeneration. Our previous studies demonstrated the presence of cholinergic receptors in SCs. In particular, the α7 nicotinic acetylcholine receptors (nAChRs) are expressed in...

In order to solve the difficulties of dispatching the regional integrated energy system (RIES) under the operating conditions of multi-energy complementary mechanisms, as well as to achieve the purpose of economic operation and low carbon operation of the system, an optimal dispatching model of RIES, including demand response (DR) and...

The gut plays a key role in drug absorption and metabolism of orally ingested drugs. Additionally, the characterization of intestinal disease processes is increasingly gaining more attention, as gut health is an important contributor to our overall health. The most recent innovation to study intestinal processes in vitro is the...
