Dreams result from a process that often combines fragments of multiple life experiences and anticipates future events, according to novel evidence from a new study.

A study of the associations between drinking alcohol and the chances of becoming pregnant suggests that women who want to conceive should avoid heavy drinking. In the second half of menstrual cycle even moderate drinking is linked to reduced chances of pregnancy. The study is published in Human Reproduction journal.

Researchers at University of California San Diego School of Medicine used a combination of modalities, such as measuring brain function, cognition and lifestyle factors, to generate individualized predictions of depression.

As new research on anaesthesia trainee morale is published, an impassioned plea is today being made in an open letter from the Association of Anaesthetists to the UK's four Health Secretaries: to urgently double the number of training posts for anaesthetists this summer and for subsequent years.

Influences on Discharge Partitioning on a Large River Delta: Case Study of the Mississippi-Atchafalaya Diversion, 1926-1950, seeks to resolve lingering questions about the rate at which the Atchafalaya River captured water from the Mississippi River and the degree to which it would have changed the course of the river.

The Institute for Bioengineering of Catalonia (IBEC) and DAM Company develop a system equipped with chemical sensors that provides information, in real time, on the intensity and location of odor sources in the Waste Water Treatment Plants (WWTP).

Why did the deer cross the road? According to research from the University of New Hampshire to keep going and going and going. Researchers have discovered the longest distance ever recorded by an adult male white-tailed deer--300 kilometers, or close to 200 miles, in just over three weeks. The finding has important implications for population management and the transmission of disease, especially chronic wasting disease, a fatal neurological disease.

The speed of water flow is a limiting factor in many membrane-based industrial processes, including desalination, molecular separation and osmotic power generation. Researchers at The University of Manchester have published a study revealing a dramatic decrease in friction when water is passed through nanoscale capillaries made of graphene. In contrast, capillaries made from hexagonal boron nitride (hBN) - which has a similar surface topography and crystal structure as graphene - display high friction.

Researchers from the University of Liège (Belgium) have recently developed a new artificial neuron inspired by the different modes of operation of human neurons. Called a Bistable Recurrent Cell (BRC), this process has enabled recurrent networks to learn temporal relationships of more than a thousand discrete time units where classical methods failed after only a hundred time units.

Drones and artificial intelligence can monitor large colonies of seabirds as well as traditional on-the-ground methods, while reducing costs, labor and the risk of human error, a new study finds. Scientists at Duke University and the Wildlife Conservation Society used an AI deep-learning algorithm to analyze more than 10,000 drone images of mixed colonies of seabirds in the Falkland Islands/Malvinas. The algorithm's automated counts closely matched human counts 90% of the time.

A research team from the University of Massachusetts Amherst has created an electronic microsystem that can intelligently respond to information inputs without any external energy input, much like a self-autonomous living organism. The microsystem is constructed from a novel type of electronics that can process ultralow electronic signals and incorporates a device that can generate electricity "out of thin air" from the ambient environment.

QurAlis Corporation today announced the publication of an article in Cell Reports titled Human Amyotrophic Lateral Sclerosis Excitability Phenotype Screen: Target Discovery and Validation by QurAlis founders Kasper Roet, Ph.D., Clifford Woolf, M.D., Ph.D., and Kevin Eggan, Ph.D., who pioneered a high-content, live-cell imaging screen using ALS patient-derived motor neurons in combination with a compound library generated by Pfizer to identify drug targets to treat hyperexcitability induced neurodegeneration in ALS patients.

The analysis of very old plant fossils discovered in South Africa and dating from the Lower Devonian period documents the transition from barren continents to the green planet we know today. Cyrille Prestianni, a palaeobotanist at the EDDy Lab at the University of Liège (Belgium), participated in this study, the results of which have just been published in the journal Scientific Reports.

The bubbles created by intense focused lasers in this experiment were ten times smaller and contained water vapour at a pressure around a hundred thousand times higher than orginary bubbles in water. They expand at supersonic speed, pushing a shockwave in front. Researchers led by University of Göttingen with Deutsches Elektronen-Synchroton (DESY) and European X-Ray Free-Electron Laser (European XFEL), used holographic flash imaging and X-ray laser pulses to make images. Research appears in Nature Communications.

Preliminary results from a study of more than 700,000 patients with traumatic brain injury (TBI) show that those with a sleep disorder had an increased risk of developing dementia.

A recent study of teens and young adults found that several factors related to sleep timing and sleep duration are associated with an increased risk of cannabis use and binge drinking of alcohol during the following year.

In a recent study, University of Rochester and University of Michigan political scientist examined two common policy interventions--economic and psychological--designed to counter the growing radicalization in the US. They found that improving economic conditions reduces both radicalization efforts and dissent. However, trying to render people psychologically less susceptible to radicalization can backfire and instead increase radical leaders' efforts to influence and radicalize more followers.

Cities located in metropolitan areas of this Brazilian state score better according to an index that measures the existence of public policies designed to adjust critical sectors to the impacts of climate change.

Researchers have shown that even after lung tissue has been damaged, it may be possible to reverse fibrosis and promote tissue repair through treatment with microgel-coated mesenchymal stromal cells.

Despite updates from the World Health Organization, the U.S. Centers for Disease Control and Prevention (CDC) and the Public Health Agency of Canada that the virus can be transmitted by short- and long-range aerosols, Canada's public health guidance has not been adequately updated to address this mode of transmission, argue authors of a commentary published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/content/early/2021/06/08/cmaj.210830.
