Drugs that stop mosquitoes catching malaria could help eradicate the disease

Lun, 09/17/2018 - 22:00
Researchers have identified compounds that could prevent malaria parasites from being able to infect mosquitoes, halting the spread of disease.

Searching for clues on extreme climate change

Lun, 09/17/2018 - 22:00
Nearly 13,000 years ago, pines in southern France experienced a cold snap, which scientists have now reconstructed. The study about the consequences of a drastic climate change event in past and its implications for our future will be published tomorrow in Scientific Reports. The authors are from GFZ Potsdam, Berlin, the UK, Switzerland, and France.

Scientists use artificial neural networks to predict new stable materials

Lun, 09/17/2018 - 22:00
Artificial neural networks -- algorithms inspired by connections in the brain -- have 'learned' to perform a variety of tasks, from pedestrian detection in self-driving cars, to analyzing medical images, to translating languages. Now, researchers at the University of California San Diego are training artificial neural networks to predict new stable materials.

Grad students will be future professors, but are they learning how to teach effectively?

Lun, 09/17/2018 - 22:00
A new Portland State University study found that graduate students are on board with wanting to adopt interactive teaching methods but often don't get the training or support they need from their institutions to do so.

Long-term success of ACL reconstruction is connected to way you move post-surgery

Lun, 09/17/2018 - 22:00
Researchers from the University of North Carolina and Brigham Young University conducted a study to observe walking biomechanics of 130 subjects who have had ACL reconstruction surgery. They found people who report lingering symptoms post-surgery either underload their injured leg (6-12 months after surgery) or overload the injured leg (after the 24-month mark), as compared to those who have had the surgery but no longer report symptoms.

Anxiety surrounding mass shootings briefly closes ideological divides

Lun, 09/17/2018 - 22:00
People who feel anxious surrounding mass shootings tend to abandon their political ideology on typically divided issues, according to a study by two University of Kansas professors.

Do we trust people who speak with an accent?

Lun, 09/17/2018 - 22:00
A recently published study shows that unless they speak in a confident tone of voice, you're less likely to believe someone who speaks with an accent. And, interestingly, as you make this decision different parts of your brain are activated, depending on whether you perceive the speaker to be from your own 'in-group' or from some type of 'out-group' (e.g., someone with a different linguistic or cultural background).

Small molecule plays big role in weaker bones as we age

Lun, 09/17/2018 - 22:00
With age, expression of a small molecule that can silence others goes way up while a key signaling molecule that helps stem cells make healthy bone goes down, scientists report.

Research shows that busy people make healthier choices

Lun, 09/17/2018 - 22:00
A busy mindset can be leveraged to promote better self-control.

Sleep deprived people more likely to have car crashes

Lun, 09/17/2018 - 22:00
A new study in SLEEP indicates that people who have slept for fewer than seven of the past 24 hours have higher odds of being involved in and responsible for car crashes. The risk is greatest for drivers who have slept fewer than four hours.

Women who experienced higher levels of trauma gave birth to significantly smaller male babies

Lun, 09/17/2018 - 22:00
In the first study of its kind, researchers from the Icahn School of Medicine at Mount Sinai have found significantly lower birth weights in male infants -- an average decrease of 38 grams, or approximately 1.3 ounces -- born to women who had been exposed to trauma at some point in their lives and who secreted higher levels of cortisol, a hormone related to stress, in late pregnancy.

Transparent loudspeakers and MICs that let your skin play music

Dom, 09/16/2018 - 22:00
An international team of researchers, affiliated with UNIST has presented an innovative wearable technology that will turn your skin into a loudspeaker.

Neuroscience of envy: Activated brain region when others are rewarded revealed

Dom, 09/16/2018 - 22:00
National Institute for Physiological Sciences researchers showed that part of the macaque brain alters the sense of value felt upon receiving a reward in a manner dependent on the receipt of rewards by one's peers. This finding on the neuroscience of envy provides insight into how all primates, including humans, compare their material wellbeing with that of others and are potentially motivated to compete for limited resources.

Oregon chemists create circular fluorescent dyes for biological imaging

Dom, 09/16/2018 - 22:00
University of Oregon chemists have created a new class of fluorescent dyes that function in water and emit colors based solely on the diameter of circular nanotubes made of carbon and hydrogen.

Enlarged genotype-phenotype correlation for a deletion in neurofibromatosis type 1

Dom, 09/16/2018 - 22:00
International collaborative research led by Ludwine Messiaen, Ph.D., shows that while a three-base pair, in-frame deletion called p.Met992del in the NF1 gene has a mild phenotype for people with the genetic disorder neurofibromatosis type 1, or NF1, the mutation does cause complications. These include non-optic brain tumors, mostly low-grade and asymptomatic, as well as cognitive impairment and/or learning disabilities. This study extends findings first reported in 2007 that included only 19 NF1 adults.

Magellanic Clouds duo may have been a trio

Dom, 09/16/2018 - 22:00
Two of the closest galaxies to the Milky Way--the Large and Small Magellanic Clouds--may have had a third companion, astronomers believe.Research published today describes how another 'luminous' galaxy was likely engulfed by the Large Magellanic Cloud some three to five billion years ago.

New insights into DNA phase separation

Dom, 09/16/2018 - 22:00
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has presented the notion of 'DNA Phase Separation', which suggests that the DNA within the nucleus may trigger phase separation, like oil in water.

Four-year study: Pioneering contact lens approach slows myopia progression in children

Dom, 09/16/2018 - 22:00
New four-year study data shows the significant impact of a pioneering contact lens management approach to slowing the progression of myopia (nearsightedness) in children, including those whose treatment begins later. CooperVision is presenting the latest outcomes during the BCLA Asia conference in Singapore this week, at which the globally increasing prevalence of myopia is among the most widely discussed issues.

Exposure to organochlorine pesticides in the womb linked to poorer lung function in childhood

Dom, 09/16/2018 - 22:00
Babies exposed to higher levels of organochlorine compounds in the womb go on to have worse lung function in childhood, according to new research presented today (Tuesday) at the European Respiratory Society International Congress. These compounds, which include the pesticide DDT, as well as electrical insulators and other industrial products, are now banned in most parts of the world. However, because they degrade very slowly, they are still present in the environment and in foods.

COPD patients suffer fewer respiratory problems if treated with targeted lung denervation

Dom, 09/16/2018 - 22:00
First results from a clinical trial of a procedure to open obstructed airways in patients with chronic obstructive pulmonary disease (COPD) have shown that it significantly reduces problems associated with the disease and is safe. Then findings on targeted lung denervation are presented at the European Respiratory Society International Congress.
