A study by CSIRO Australia found that the frequency of extreme storm surge events generated by Adriatic Sea tempests could fall by about 30 percent by 2100. This reduction in extreme events may have beneficial consequences for the conservation of Venice, a World Heritage-listed city built on 117 small islands.
Researchers at Oregon State University have successfully prototyped a new energy technology that captures and uses low-to-medium grade waste heat from various sources. The system achieved an impressive 80% conversion efficiency in turning wasted heat into cooling capability, outperforming current approaches.
Researchers have created a 3-D movie of brain activity while an individual loses consciousness, revealing a change in electrical activity and communication between brain cells. The findings support a hypothesis that consciousness is formed by neural assemblies, which work efficiently together or not, depending on sensory stimulations.
Girls with ADHD symptoms are more predictive of adverse substance use outcomes, including alcohol abuse and dependence. Parents' reports of inattentiveness in daughters at age 11-12 can predict illicit drug use across adolescence.
A new analysis found mortality from all causes to be higher in patients with chronic hepatitis C infection. The study, published in Clinical Infectious Diseases, compared mortality rates among 9,378 adults with and without hepatitis C and found a two-fold increased risk of death from both liver- and non-liver related causes.
A UGA study examines discussions in over 200,000 participants across 35 newsgroups and finds that popular posters attract most replies, with content sourced from traditional media and blogs.
System 94L is making slow progress in a north-northeasterly direction, bringing clouds to eastern Cuba and the Bahamas. A 60% chance of showers and thunderstorms is forecast for the Bahamas as the low approaches, with a northeasterly track expected over the weekend.
The National Toxicology Program has added eight substances to the HHS Report on Carcinogens, identifying chemicals that may increase cancer risk. These include formaldehyde, a known human carcinogen linked to nasal and other cancers, and captafol, a fungicide with limited evidence of lung cancer.
A study presents a linear relationship between carbohydrate craving and sleep deprivation among high school seniors, finding excessive daytime sleepiness increases carb cravings. The research also reveals a higher rate of depression and stronger cravings for carbohydrates in students with severe sleep deprivation.
The new guidelines provide evidence-based recommendations for optimal care of patients with hyperthyroidism, including treatment options and patient management strategies. The guidelines are a comprehensive update to previous versions and highlight the latest scientific literature and expert experience.
Astronomers have discovered a second supersized black hole at the heart of the unusual nearby galaxy Markarian 739. The study used NASA's Swift satellite and Chandra X-ray Observatory to find the hidden AGN, which is one of the nearest and clearest cases of a binary AGN. The dual black holes are separated by only 11,000 light-years.
Researchers have sequenced two isolates from an E. coli outbreak, providing valuable genomic information to aid in understanding the origins of highly pathogenic strains. The genome annotations reveal unique islands and proteins that may hold clues to virulence or intervention strategies for the new strains.
U-M researchers found that attacking specific microRNA molecules can reduce deaths from sepsis. The approach also holds promise for other inflammatory diseases like juvenile rheumatoid arthritis and graft-vs.-host disease.
A study found that poor sleep hygiene in high school is associated with lower grades in college, but shifts towards a morning chronotype can improve academic performance. Students who are 'evening types' initially struggle, but adapt and show significant improvement by the senior year.
A study of 1,811 pairs of twins found that shorter sleep durations were associated with increased expression of genes related to obesity, while longer sleep durations were linked to decreased body mass index. This suggests that genetic influences on body weight may be suppressed by adequate sleep duration.
Research by Brown University economists finds that daily polling data responds to returns from primary victories, with early voters having a disproportionate impact on candidate momentum. This can lead to candidates spending more resources in early states, potentially altering the nomination outcome.
A study found that Iraq and Afghanistan veterans who visited a VA integrated care clinic were more likely to undergo initial mental health and social work evaluations than those visiting standard clinics. The integrated care model increased the rate of initial mental health evaluations, especially for women veterans, younger veterans, ...
Researchers at Brookhaven National Laboratory found that thin layers of copper-oxide materials exhibit wild electron spin fluctuations, a hallmark of quantum spin liquids. This discovery may be crucial to understanding high-temperature superconductivity.
NASA satellite imagery shows Adrian's eye despite overcast clouds, revealing strong thunderstorms and a minimum central pressure of 948 millibars. The storm is expected to stay at sea but will stir up rough surf along the southwestern coast of Mexico.
A study finds that sleepiness in college students leads to counterfactual thinking, including thoughts of how others could have done better. Sleepy individuals are also more likely to engage in displaced aggression and plan revenge.
A study found that weekend sleep fails to reverse performance decline after a workweek of restricted sleep, but women may fare better. Women showed less subjective sleepiness and performance deterioration during sleep restriction, as well as greater improvements after recovery.
Research suggests that analyzing breathing sounds while awake can accurately predict obstructive sleep apnea (OSA) severity. Breathing patterns and pharyngeal pressure play a significant role in OSA diagnosis, making sound analysis a viable diagnostic tool.
Proactive telephone counseling helps increase long-term smoking cessation, with a positive effect on both point prevalence and prolonged abstinence. The study suggests that active recruitment methods do not significantly impact quit rates, contrary to previous assumptions.
A study found that non-invasive ventilation used as a weaning technique can shorten intubation time and reduce the risk of post-extubation acute respiratory failure. Additionally, NIV used as a rescue therapy significantly reduces the risk of reintubation and death in patients with chronic hypercapnic respiratory failure.
Researchers investigated problem-solving abilities and innovative capacities of kea and New Caledonian crow. The studies revealed that both species employ various tools to achieve food rewards, with the kea mastering compact object tools and the crow using elongated objects like sticks to probe for grubs.
NASA's Landsat 5 satellite captured an image of the long damage track created by a Massachusetts tornado on June 1, 2011. The satellite also provided an earlier image from 2010 for comparison, enabling clearer visualization of the tornado's eastward track.
Tropical Storm Sarika is bringing heavy rainfall to the South China Sea, with satellite imagery showing strongest thunderstorms south of the storm's center. Infrared satellite imagery reveals a fully exposed low-level circulation center, weakening the storm's circulation.
Researchers found that studying both types of stem cells has become more common, with a growing proportion of papers combining adult and embryonic stem cells. This means that banning either type of research could harm the field overall. The study suggests that federal funding for one area could negatively impact the other.
Johns Hopkins researchers have discovered a direct link between MCM proteins and the oxygen-sensing HIF-1 protein. The study found that MCM proteins mediate crosstalk between cell division machinery and environmental factors, controlling cell growth based on oxygen availability.
