Astronomers have found a small planet with a mass about five times that of Earth, orbiting a small star near the center of the galaxy. The discovery suggests there are many other small planets in habitable zones, where temperatures are moderate enough for liquid water to appear on their surfaces.
Researchers from Max Planck Institute used data from a popular internet game to analyze banknote movements, finding universal scaling laws that govern human travel behavior. These laws provide insight into the statistical rules governing the spread of diseases.
Researchers found that anxious fathers can increase a mother's pain experience after a caesarean delivery. Preparing the birth partner through antenatal classes and pre-operation support may reduce post-operative pain and improve the birth experience.
A recent study by Dr. Luisa Borrell at Columbia University's Mailman School of Public Health reveals a racial disparity in hypertension among Hispanics, suggesting that being Black within this ethnic group is associated with the highest prevalence of high blood pressure. The research highlights the importance of addressing health inequ...
A new robot system developed by Dmitry Oleynikov and colleagues enables surgeons to visualize the abdominal cavity using minimal incisions, allowing for less trauma and potentially reducing scars. The device is controlled from a console and can be inserted through small incisions, allowing for more flexibility in surgical procedures.
Astronomers have discovered the first and only icy exoplanet that matches theoretical predictions for Solar System formation. OGLE-2005-BLG-390Lb orbits a small red star at an extremely close distance, with a surface temperature of -220°C, and is likely to resemble Pluto more than rocky planets like Earth.
Research highlights the impact of aerosols on ocean temperature, with manmade aerosols delaying warming by several decades. Ship emissions also make clouds brighter and higher near European harbors.
The discovery of OGLE-2005-BLG-390Lb provides strong evidence that low-mass planets, potentially supporting life, are more common than Jupiter-like gas giants. Researchers hope the gravitational microlensing technique will reveal more habitable worlds in the Milky Way galaxy.
A comprehensive review of 29,000 individuals across 22 studies found that mentally stimulating leisure activities can significantly reduce dementia risk. Individuals with high brain reserve have a 46% decreased risk of dementia compared to those with low brain reserve.
Researchers at the University of Pittsburgh have developed a method using carbon nanotubes to detect single DNA base mutations. The technique produces sensor results comparable to state-of-the-art optical techniques and has several advantages over existing methods, including cost, time, and simplicity.
A demographic analysis reveals significant disparities between damaged areas and undamaged zones, with black and poor residents facing greater odds of harm. The findings have implications for the future of the Gulf region, particularly in New Orleans.
Scientists have identified two large subglacial lakes beneath the Antarctic ice sheet, 90ºE and Sovetskaya. These lakes are estimated to be around 2,000km2 and 1,600km2 in size, respectively, and are sealed beneath over two miles of ice.
A recent study suggests that U.S. Hispanics have lower rates of high blood pressure than non-Hispanics, but this advantage disappears when race is accounted for. The research found that black Hispanics exhibit the highest prevalence of hypertension, regardless of their ethnicity.
Researchers found that Magellanic Penguins in Argentina's largest colony can handle up to 70,000 annual visitors without significant stress or harm. However, the study highlights the challenges of quantifying long-term consequences of human disturbance on wildlife.
A study by cognitive psychologists Helga Noice and Tony Noice found that actors acquire lines quickly by focusing on the character's intention, rather than just memorizing the words. This 'active experiencing' principle is effective not only for actors but also for improving memory and cognition in older adults.
Researchers found that the Runx1 gene is essential for the development and function of nociceptive sensory neurons, which are responsible for sensing pain. The study reveals that Runx1 regulates the specification of these neurons and their wiring, providing a genetic basis for chronic pain.
A study led by scientists at Einstein and Beth Israel found a significant link between the G2019S LRRK2 gene mutation and Parkinson's disease in Ashkenazi Jewish patients. The mutation was detected in 18.3% of patients, highlighting the importance of genetic counseling for early detection and diagnosis.
A new study reveals that plant metabolic rates are driven by nitrogen content, which has significant implications for understanding the global carbon cycle. By estimating nitrogen content, scientists can model plant metabolism and better assess the global plant metabolic rate.
Researchers are investigating delivering chemotherapy drugs directly to breast ducts to treat early breast cancer. Studies in rats and mice show promising results, with tumors shrinking or disappearing after treatment. The procedure aims to minimize disfigurement and spare normal tissues.
Researchers at UW-Madison have discovered a systematic mechanism for the influenza virus to package its genetic materials, enabling the development of new antiviral drugs and more efficient vaccine production. This finding has significant implications for addressing avian influenza pandemics.
Researchers used a popular internet game to study human travel patterns in the US, revealing statistical laws that can be applied to model infectious disease spread. The breakthrough model considers variables such as population density and transportation modes, offering improved predictions for future pandemics.
Researchers estimate that copper and zinc reserves are not enough to meet future demands if all nations adopt modern technologies, threatening sustainable resource use. The study suggests that scarce metals like platinum risk depletion in this century due to lack of substitutes.
A study has found that vaginal oestrogen can increase systemic oestradiol levels in women on aromatase inhibitors (AI) for breast cancer, potentially counteracting AI treatment. Researchers recommend avoiding the combination of AIs and vaginal oestrogens, except in exceptional circumstances.
The study found a 25% overall decrease in the risk of death following care in a trauma center compared to non-trauma centers. Trauma centers also showed lower mortality rates for patients one year after injury.
Despite having more free time, women experience a 'family penalty' from childcare and housework responsibilities. A study found that married women with children feel 2.2 times more rushed than single, childless women.
Astronomers have detected a rocky, icy planet about five-and-a-half times the mass of Earth, located over 20,000 light years away. The discovery was made possible by gravitational microlensing, which may lead to finding smaller planets in habitable zones around stars.
Two studies found that 44% of geneticists and 32% of other life scientists reported witholding data from colleagues, while trainees reported difficulties accessing information and resources. Data withholding was more common in highly competitive settings and associated with industry relationships.
A study using satellite data found that indigenous lands are highly effective in stopping deforestation, with some areas showing less than 1% inner deforestation rates despite high rates of outer deforestation. This contradicts the assumption that indigenous peoples will cease to protect forests with acculturation.
