Chinese scientists have recently shown how the tiny apex structure in plant leaves controls water drainage and confers an evolutionary advantage.
The research was conducted by Prof. JIANG Lei's team at the Technical Institute of Physical Chemistry of the Chinese Academy of Sciences. Results were published online in PNAS Jan. 13.
AURORA, Colo. (Jan. 15, 2020) - A byproduct of glucose called lactate, used by every cell in the body, may also prompt a mutated cell to become cancerous, according to new research from the University of Colorado Anschutz Medical Campus.
The study was published Tuesday in the journal Frontiers in Oncology.
La Trobe University researchers have found introducing a minimum unit price (MUP) of $1.30 per standard drink across Australia could dramatically reduce alcohol consumption.
Such a policy, already proven successful in Canada and Eastern Europe, could reduce drinking in Australia by 1.5 standard drinks per week on average and 12 drinks per week for harmful drinkers.
La Trobe Centre for Alcohol Policy Research (CAPR) health economist Dr Jason (Heng) Jiang said alcohol affordability in Australia has remained relatively unchanged over the last 30 years.
At around 1 a.m. local standard time on April 29, 2017, a fireball flew over Kyoto, Japan. Compared to other fireballs spotted from Earth, it was relatively bright and slow. Now, scientists have determined not only what the fireball was, but also where it came from.
"We uncovered the fireball's true identity," says Toshihiro Kasuga, paper author and visiting scientist at the National Astronomical Observatory of Japan and Kyoto Sangyo University. "It has a similar orbit to that of the near-Earth asteroid 2003 YT1, which is likely its parent body."
The public should be wary of searching for probiotic information online as most webpages originate from unreliable sources and the health-benefit claims are often not supported by robust scientific evidence.
A new study, published in Frontiers in Medicine, cautions that while Google is adept at sorting the most reliable websites to the top of the list, the majority of websites providing information on probiotics are from commercial sources.
Bottom Line: American cancer survivors, particularly those 64 years or younger, faced substantial medical financial hardship and sacrifices in spending, savings, or living situation, according to data from a survey.

Preaching sexual abstinence to youth was popular for a number of decades, but research repeatedly found that such educational messages fell short in their intended goals. Simply telling youth not to have sex failed to delay the initiation of sex, prevent pregnancies, or stop the spread of sexually-transmitted diseases. Since the advent of photo- and video-sharing via phones, children have received similar fear-based messages to discourage sexting - the sending or receiving of sexually explicit or sexually suggestive images (photos or video) usually via mobile devices.
One in six women experience long-term post-traumatic stress following miscarriage or ectopic pregnancy.
This is the finding of the largest ever study into the psychological impact of early-stage pregnancy loss, from scientists at Imperial College London and KU Leuven in Belgium.
In mammals, pair bonds are very rare, one of the few exceptions being the red titi monkeys of South America. These relatively small tree dwellers live in pairs or small family groups and are characterized by the fact that the males take intensive care of their offspring. A team of researchers from the German Primate Center - Leibniz Institute for Primate Research has now investigated how pair relationships work in titi monkeys.
Some forms of camouflage have evolved in animals to exploit a loophole in the way predators perceive their symmetrical markings. The University of Bristol findings, published in Proceedings of the Royal Society B today [15 Jan], describe how animals have evolved to mitigate this defensive disadvantage in their colouration.
Areas of high HIV prevalence, known as 'hotspots', do not necessarily fuel the epidemic in the wider population, say researchers.
Hotspots are often targeted for intense HIV control interventions, including treatment and prevention, to maximise their effect and reach the people in greatest need first.
These strategies often assume that hotspots are also sources of disease transmission to other areas, and that targeting hotspots will have the added indirect benefit of reducing new HIV infections in the wider population.
The federal government has allocated only about 2 percent of its transportation funds to encourage walking and cycling, not nearly enough to make a significant difference, according to Ralph Buehler, associate professor and chair of the urban affairs and planning program in the Virginia Tech School of Public and International Affairs.
MALIBU, Calif. January 10, 2019-- HRL Laboratories, LLC, researchers have published results showing that targeted transcranial electrical stimulation during slow-wave sleep can improve metamemories of specific episodes by nearly 20% after only one viewing of the episode, compared to controls. Metamemory describes the sensitivity of whether memories are recalled accurately or not, such as during eyewitness testimony.
New York, NY--January 13, 2020--A recent decision by the National Transpiration Safety Board (NTSB) on the March 2018 Uber crash that killed a pedestrian in Arizona split the blame among Uber, the company's autonomous vehicle (AV), the safety driver in the vehicle, the victim, and the state of Arizona. With the advent of self-driving cars, the NTSB findings raise a number of questions about the uncertainty in today's legal liability system. In an accident involving an AV and a human driver, who is liable? If both are liable, how should the accident loss be apportioned between them?
New research co-authored by Yanwen Wang, an assistant professor in the UBC Sauder School of Business, reveals that the resale ticket market also appeals to sports fans who normally buy season tickets.
Resale ticket markets -- also known as secondary ticket markets -- allow season ticket holders to recoup costs by selling unneeded tickets, as well as creating an alternative supply of tickets that reduce the need for fans to commit to a season's pass.
It turns out this isn't just beneficial for fans - it also boosts team revenues.
