This research was published on October 14 in the Phytotaxa.
New research, led by the University of Southampton, has found that human activities such as shipping are having a noticeable impact on marine species and their native habitats.
Low socio-economic status and fear of abandonment early in life can lead to poor health in adulthood, regardless of adult socio-economic status, according to a new study from psychologists at Rice University.
First-ever study to demonstrate the viability of an alternative remagnetization technique that could be used in ultrafast computer memory, instead of the conventional method that relies on external magnetic fields.
Using data from deep-space surveys taken by NASA's Hubble Space Telescope and other observatories, astronomers have performed a census of the number of galaxies in the universe. The team came to the surprising conclusion that there are at least 10 times as many galaxies in the observable universe than previously thought. The results have clear implications for our understanding of galaxy formation, and also helps shed light on an ancient astronomical paradox — why is the sky dark at night?
As they grow, corals are bathed in a sea of marine microbes, such as bacteria, algae, and viruses. While these extremely abundant and tiny microorganisms influence coral communities in a variety of ways, a new study by researchers at the Woods Hole Oceanographic Institution (WHOI), the Bermuda Institute of Ocean Sciences (BIOS) and University of California, Santa Barbara (UCSB) reveals that corals also have an impact on the microbes in waters surrounding them.
More aridity is sending thousands of square miles up in flames
Planets that revolve around two suns may surprisingly survive the violent late stages of the stars’ lives, according to new research out of the NASA Goddard Space Flight Centre and York University. The finding is surprising because planets orbiting close to a single sun, like Mercury and Venus in our solar system, would be destroyed when the aging star swells into a red giant.
Wyss Institute materials scientists have bioprinted a tubular 3-D renal architecture that recapitulates functions of the kidney.
While male and female mice have similar responses to physical stress, research from the Hotchkiss Brain Institute at the University of Calgary, Canada, suggests females, not males, feel stressed when alone.
Growing up in a warm family environment in childhood is associated with feeling more secure in romantic relationships in one's 80s, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The findings show that men who grew up in caring homes were more adept at managing stressful emotions when assessed as middle-aged adults, which helps to explain why they had more secure marriages late in life.
Biologists sequencing the genome of the WO virus, which infects the bacterial parasite Wolbachia, have discovered that the phage carries DNA that produces black widow spider toxin: the first time an animal-like DNA has been found in such a virus.
The first documented evidence of wild chimpanzee mothers teaching their offspring to use tools has been captured by video cameras set to record chimpanzee tool-using activity at termite mounds in the Nouabalé-Ndoki National Park in the Republic of Congo, according to new research from anthropologists at Washington University in St.
Researchers have prevented the development of Alzheimer's disease in mice by using a virus to deliver a specific gene into the brain.
Amid efforts to restore native oyster populations on the West Coast, how are oysters expected to fare under climate change in the decades and centuries to come? Not too badly, according to a study from the University of California, Davis. But there’s a big “if” involved.
Hundreds of millions of people rely on Internet or app-based symptom checkers to help make sense of symptoms or self-diagnose diseases. The first direct comparison shows human doctors outperform digital ones in diagnostic accuracy.
Will astronauts traveling to Mars remember much of it? That’s the question concerning University of California, Irvine scientists probing a phenomenon called “space brain.” UCI’s Charles Limoli and colleagues found that exposure to highly energetic charged particles – much like those found in the galactic cosmic rays that will bombard astronauts during extended spaceflights – causes significant long-term brain damage in test rodents, resulting in cognitive impairments and dementia.
A multi-institute study led by Monash University has revealed for the first time the mechanism that regulates fluid intake in the human body and stops us from over-drinking, which can cause potentially fatal water intoxication. The study challenges the popular idea that we should drink eight glasses of water a day for health.
Bonobos, chimpanzees and orangutans understand that others can be convinced of something that is not true, says a study by researchers of Duke University, Kyoto University, the University of St. Andrews and the Max Planck Institute for Evolutionary Anthropology.
A new systematic review and meta-analysis of randomized controlled trials has concluded that eating oat fibre not only reduces LDL cholesterol (bad cholesterol), but non-HDL cholesterol and apolipoprotein B as well.
New research, led by the University of Southampton, has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain.
A survey of international members of the American Thoracic Society (ATS) found that 96 percent of respondents agreed that climate change is occurring and 81 percent indicated that climate change has direct relevance to patient care. Compared to a similar survey of American ATS members, more international physician members reported that climate change was affecting their patients “a great deal” or a “moderate amount” (69 percent international vs. 44 percent U.S.).
A new therapeutic target for the treatment of compulsive binge eating has been identified by researchers at Boston University School of Medicine (BUSM).
New research has found that working night shifts has little or no effect on a woman's breast cancer risk despite a review in 2007 by the International Agency for Research on Cancer (IARC) classifying shift work disrupting the 'body clock' as a probable cause of cancer.
Spring is beginning earlier than its historical average in three-quarters of United States’ national parks studied in new research that employed models created by UWM climatologist Mark Schwartz.
Tarsiers – tiny, carnivorous primates – are our distant cousins, according to scientists at Washington University School of Medicine in St. Louis who sequenced and analyzed the tarsier genome. Their findings place tarsiers on the evolutionary branch that leads to monkeys, great apes and humans.
In a collaborative effort with scientists at six Colombian hospitals, Johns Hopkins Medicine researchers report what they believe to be the strongest biological evidence to date linking Zika virus infection and Guillain-Barré syndrome.
In a new study, scientists in London, Ontario have discovered that early marijuana use may result in abnormal brain function and lower IQ.
How do you know when it's time for an older adult with mild dementia to stop driving? Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. It can impact a person's ability to drive safely. Although all people with dementia will have to stop driving eventually, each case can be unique based on the individual. According to a new study published in the Journal of the American Geriatrics Society, we still need to explore mental or physical tests that can best predict when people with dementia should stop driving.
In a paper published in the academic journal Nature Communications, ISU scientists identified a protein that may safeguard neurons from the ravages of Parkinson’s disease.
