Delivery services have increased rapidly with the expansion of online shopping and, in Japan, failed deliveries that result in redelivery attempts occur 20% of the time. In terms of labor, fuel, and environmental (increased CO2 emissions) costs, empty homes causing redeliveries have become an issue. Until now, long-term trends of households with every member out-of-home has not been fully clarified.
Mangroves account for only 0.7 per cent of the Earth's tropical forest area, but they are among the world's most productive and important ecosystems. They provide a wealth of ecological and socio-economic benefits, such as serving as nursery habitat for fish species, offering protection against coastal surges associated with storms and tsunamis, and storing carbon.
Researchers from Tokyo Medical and Dental University (TMDU) discover a novel mechanism by which immunodeficiency viruses evolved over time to evade the protective measures of the host
Red panda population genomics confirms two phylogenetic species and different evolutionary histories
The red panda (Ailurus fulgens) is an endangered mammal endemic to the Himalaya and Hengduan Mountains, and its distribution spans China, Myanmar, Bhutan, India and Nepal. Prior to 1902, all red pandas were classified as one species. However, in 1902, scientists established two subspecies, based on their morphological differences: the Himalayan subspecies (A. f. fulgens) and the Chinese subspecies (A. f. styani).
Researchers identified an increased prevalence of five traits associated with previous extinction-survival responses among corals.
Human-driven climate change is rapidly increasing stressors on coral communities, such that 75% of species could become extinct within the next few centuries.
NEW YORK, March 3, 2020 -- A study published Tuesday in Scientific Reports shows that stony corals, which provide food and shelter for almost a quarter of all ocean species, are preparing for a major extinction event.
Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations performed at the University of Groningen, supported by experiments, provide a molecular view on this very fundamental process. The results were published in the journal Proceedings of the National Academy of Sciences on 2 March.
University of Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women.
The detection of sexual arousal through smell may function as an additional channel in the communication of sexual interest and provide further verification of human sexual interest.
Scientists at the Laboratoire des Maladies Neurodégénératives (CNRS/CEA/Université Paris-Saclay) and the Neurocentre Magendie (INSERM/Université de Bordeaux) have just shown that a metabolic pathway plays a determining role in Alzheimer's disease's memory problems. This work, published on 3 March 2020 in Cell Metabolism, also shows that supplying a specific amino acid as a nutritional supplement in a mouse model of Alzheimer's restores spatial memory affected early. This is a promising path for reducing memory loss related to that disease.
Studying the inner ear of apes and humans could uncover new information on our species' evolutionary relationships, suggests a new study published today in eLife.
A black hole, ejecting material at close to the speed of light, has been observed using e-MERLIN, the UK's radio telescope array based at Jodrell Bank Observatory.
A research team based at Oxford University used e-MERLIN, as well as the VLA and MeerKAT telescopes based in the US and South Africa respectively, to track the ejecting material over a period of months.
New insight on the neural processes that drive a desire for revenge during conflict between groups has been published today in the open-access journal eLife.
Netherton syndrome, a rare skin disease caused by a single genetic mutation, is exacerbated by the presence of two common Staphylococcal bacteria living on human skin, one of which was previously thought to only offer protective properties, report University of California San Diego School of Medicine researchers.
WASHINGTON - Scientists at the Environmental Working Group and Indiana University have for the first time conducted a review of 26 fluorinated chemicals, or PFAS, and found that all display at least one characteristic of known human carcinogens.
The study, published today in the International Journal of Environmental Research and Public Health, found that the most well-studied PFAS compounds - PFOA, formerly used by DuPont to make Teflon, and PFOS, formerly an ingredient in 3M's Scotchgard - exhibit up to five key carcinogenic characteristics.
A new study in the Journal of the National Cancer Institute, published by Oxford University Press, finds improvements in five-year survival rates for all cancers in young adults. For some cancers, however, there has been little improvement since the 1970s.
Over the past several decades, treatment of cancer in adolescents and young adults (people between age 15 and 39) has evolved significantly, leading to steady improvements in estimated survival rates.
BINGHAMTON, N.Y. - Research led by faculty at Binghamton University, State University of New York has revealed the most effective hospital-based methods for reducing readmission rates.
The Patient Protection and Affordable Care Act requires the Centers for Medicare and Medicaid Services to penalize hospitals by reimbursing them at lower rates for what they consider excess readmissions when compared to expected levels of readmissions.
