Tweens and TV: 50-year survey reveals the values kids learn from popular shows Posted: 15 Mar 2021 03:06 PM PDT A new report assesses the values emphasized by television programs popular with tweens over each decade from 1967 to 2017, charting how 16 values have waxed and waned during those 50 years. How important is fame? Self-acceptance? Among the findings: Fame, after nearly 40 years of ranking near the bottom (it was 15th in 1967, 1987 and 1997), rose to the No. 1 value in 2007, then dropped to sixth in 2017.

Blight may increase public health risk from mosquito-borne diseases Posted: 15 Mar 2021 03:06 PM PDT Researchers published findings that blight leads to an increased abundance of disease-carrying mosquitoes. The researchers investigated the presence of several mosquito species in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge: the historic Garden District, a high-income neighborhood, and the Old South neighborhood, a low-income area.

An ancient Maya ambassador's bones show a life of privilege and hardship Posted: 15 Mar 2021 03:06 PM PDT An important Maya man buried nearly 1,300 years ago led a privileged yet difficult life. The man, a diplomat named Ajpach' Waal, suffered malnutrition or illness as a child, but as an adult he helped negotiate an alliance between two powerful dynasties that ultimately failed. The ensuing political instability left him in reduced economic circumstances, and he probably died in relative obscurity, according to new research.

Scientists stunned to discover plants beneath mile-deep Greenland ice Posted: 15 Mar 2021 01:56 PM PDT Scientists found frozen plant fossils, preserved under a mile of ice on Greenland. The discovery helps confirm a new and troubling understanding that the Greenland Ice Sheet has melted entirely during recent warm periods in Earth's history -- like the one we are now creating with human-caused climate change. The new study provides strong evidence that Greenland is more sensitive to climate change than previously understood -- and at risk of irreversibly melting.

Study predicts the oceans will start emitting ozone-depleting CFCs Posted: 15 Mar 2021 01:07 PM PDT The ocean, a longtime reservoir for CFC-11, will become a source of the ozone-depleting chemical by middle of next century.

When 'eradicated' species bounce back with a vengeance Posted: 15 Mar 2021 01:07 PM PDT Some invasive species targeted for total eradication bounce back with a vengeance, especially in aquatic systems, finds a new study. The study chronicles the effort -- and failure -- to eradicate invasive European green crabs from a California estuary.

Of mice and men and their different tolerance to pathogens Posted: 15 Mar 2021 01:07 PM PDT Scientists have harnessed microfluidic organs-on-chip technology to model the different anatomical sections of the mouse intestine and their symbiosis with a complex living microbiome in vitro. In a comparative analysis of mouse and human microbiomes, the researchers were able to confirm the commensal bacterium Enterococcus faecium contributes to host tolerance to Salmonella typhimurium infection.

Internet-access spending improves academic outcomes, according to study of Texas public schools Posted: 15 Mar 2021 01:07 PM PDT Increased internet-access spending by Texas public schools improved academic performance but also led to more disciplinary problems among students, a study of 9,000 schools shows.

Scientists plumb the depths of the world's tallest geyser Posted: 15 Mar 2021 01:07 PM PDT Scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring.

Exercise during pregnancy may save kids from health problems as adults Posted: 15 Mar 2021 01:07 PM PDT One day soon, a woman's first trip to the doctor after conceiving may include a prescription for an exercise program.

New AI tool can revolutionize microscopy Posted: 15 Mar 2021 11:17 AM PDT An AI tool offers new opportunities for analyzing images taken with microscopes. A study shows that the tool, which has already received international recognition, can fundamentally change microscopy and pave the way for new discoveries and areas of use within both research and industry.

What happens in your brain when you 'lose yourself' in fiction Posted: 15 Mar 2021 10:21 AM PDT If you count yourself among those who lose themselves in the lives of fictional characters, scientists now have a better idea of how that happens. Researchers found that the more immersed people tend to get into 'becoming' a fictional character, the more they use the same part of the brain to think about the character as they do to think about themselves.

European summer droughts since 2015 unprecedented in past two millennia Posted: 15 Mar 2021 10:21 AM PDT Recent summer droughts in Europe are far more severe than anything in the past 2,100 years, according to a new study.

Could we recycle plastic bags into fabrics of the future? Posted: 15 Mar 2021 10:21 AM PDT Engineers have developed self-cooling fabrics from polyethylene, commonly used in plastic bags. They estimate that the new fabric may be more sustainable than cotton and other common textiles.

Important forests and wetlands are disappearing in Belize Posted: 15 Mar 2021 10:21 AM PDT Using NASA satellite images and machine learning, researchers have mapped changes in the landscape of northwestern Belize over a span of four decades, finding significant losses of forest and wetlands, but also successful regrowth of forest in established conservation zones that protect surviving structures of the ancient Maya.

Insulin rises before cells develop resistance, new diabetes research implies Posted: 15 Mar 2021 08:50 AM PDT Researchers have now presented results that may change our basic view of how type 2 diabetes occurs. Their study indicates that free fatty acids (FFAs) in the blood trigger insulin release even at a normal blood-sugar level, without an overt uncompensated insulin resistance in fat cells.

Hidden link between cellular defense systems Posted: 15 Mar 2021 08:50 AM PDT Researchers have discovered that heparanase, HPSE, a poorly understood protein, is a key regulator of cells' innate defense mechanisms.

Lab studies of emotion and well-being may be missing real-world anxiety Posted: 15 Mar 2021 08:50 AM PDT Psychologists have been studying emotional health and well-being for decades, often having people engage in contrived laboratory experiments and respond to self-report questionnaires to understand their emotional experiences and the strategies they use to manage stress. But those hundreds of studies may have missed a pretty big complicating factor - baseline anxiety levels of the subjects -- argues a new study.

Whispers from the dark side: What can gravitational waves reveal about dark matter? Posted: 15 Mar 2021 08:50 AM PDT Researchers recently captured the first signs of very low-frequency gravitational waves. They analyzed the data and considered the possibility of whether this may point towards new physics beyond the Standard Model. They report that the signal is consistent with both a phase transition in the early universe and the presence of a field of extremely light axion-like particles (ALPs).

There might be many planets with water-rich atmospheres Posted: 15 Mar 2021 08:50 AM PDT A new study suggests that hot, rocky exoplanets could not only develop atmospheres full of water vapor, but keep them for long stretches.

Global river flow contingent upon climate change Posted: 15 Mar 2021 08:50 AM PDT Study shows that as climate change impacts extreme flows, it could be worsening river flooding or increasing water scarcity during dry seasons.

Drug delivery system: Injections or light irradiation? Posted: 15 Mar 2021 08:03 AM PDT A research team has developed near-infrared (NIR) light triggered drug delivery system.

Bacteria adapt syringe apparatus to changing conditions Posted: 15 Mar 2021 08:02 AM PDT Basic, acidic, basic again: for pathogenic bacteria such as Salmonella, the human digestive tract is a sea of change. So how do the bacteria manage to react to these changes? A team of researchers has now provided a possible explanation: pathogenic bacteria can change components of their injection apparatus on the fly - like changing the tires on a moving car - to enable a rapid response.

Largest supernova remnant ever discovered with X-rays Posted: 15 Mar 2021 08:02 AM PDT In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers have identified a previously unknown supernova remnant, dubbed "Hoinga". The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to energetic X-rays. The Hoinga supernova remnant is very large and located far from the galactic plane - a surprising first finding - implying that the next years might bring many more discoveries.

Surgery should remain as mainstay of treatment for acute uncomplicated appendicitis: Study Posted: 15 Mar 2021 08:02 AM PDT A new study has found that surgery, rather than antibiotics-only, should remain as the mainstay of treatment for acute uncomplicated appendicitis.

How do good metals go bad? Posted: 15 Mar 2021 08:02 AM PDT So-called 'bad metals' are materials right at the border between metal and insulator: tiny changes in chemical composition turn the metal into an insulator - or vice versa. Until now, it seemed that these 'bad metals' could not be explained with conventional theories. But in fact these metals are not that 'bad' after all. Upon closer inspection, their behavior fits in perfectly with what we already knew about metals.

Solving the puzzle of polymers binding to ice for Cryopreservation Posted: 15 Mar 2021 08:02 AM PDT When biological material is frozen, cryoprotectants are used to prevent the damage associated with the formation of ice during the freezing process. New polymeric cryoprotectants are emerging, alongside the established cryoprotectants, but how exactly they manage to control ice formation and growth is still largely unknown. This is especially true for PVA, a deceptively simple synthetic polymer that interacts with ice by means of mechanisms that have now been revealed at the atomistic level.

How the brain learns from subconscious stimuli Posted: 15 Mar 2021 08:02 AM PDT Researchers uncovered for the first time what happens in animals' brains when they learn from subconscious, visual stimuli. In time, this knowledge can lead to new treatments for a number of conditions.

Antarctic peninsula likely to warm over next two decades Posted: 15 Mar 2021 08:02 AM PDT An analysis of historic and projected simulations from 19 global climate models shows that, because of climate change, the temperature in the Antarctic peninsula -- long a canary in the coal mine for the rest of the continent -- will increase by 0.5 to 1.5 degrees Celsius by 2044.

Lemurs can sniff out hidden fruit from afar Posted: 15 Mar 2021 08:02 AM PDT Lemurs can use their sense of smell to locate fruit hidden more than 50 feet away in the forest -- but only when the wind blows the fruit's aroma toward them.

New class of substances for redox reactions Posted: 15 Mar 2021 08:02 AM PDT An interdisciplinary team presents a new class of chemical compounds that can be reversibly oxidized and reduced. The compounds known as 'pyrazinacenes' are simple, stable compounds that consist of a series of connected nitrogen-containing carbon rings.

Standard digital camera and AI to monitor soil moisture for affordable smart irrigation Posted: 15 Mar 2021 08:02 AM PDT Researchers have successfully tested a system that can monitor soil moisture using just a standard camera and an AI algorithm. The system holds huge potential as a simple, affordable solution for smart agriculture, allowing for automated, precision irrigation.

Public comments on orca conservation: future protection efforts Posted: 15 Mar 2021 08:02 AM PDT Researchers analyzed more than 17,000 public comments focused on orca conservation in the state of Washington and found that the most common emotional sentiments were trust, anticipation and fear.

Reducing global warming matters for freshwater fish species Posted: 15 Mar 2021 08:01 AM PDT The habitats of freshwater fish species are threatened by global warming, mainly due to rising water temperatures. A 3.2-degree Celsius increase in global mean temperature would threaten more than half of the habitat for one third of all freshwater fish species. The number of species at risk is ten times smaller if warming is limited to 1.5 degrees.

Thirteen things primary care clinics can check to help preserve brain health Posted: 15 Mar 2021 08:01 AM PDT It's important to take steps to prevent cognitive decline before changes to the aging brain take hold. Primary care is an ideal setting to address specific risk factors early and throughout life that can prevent cognitive decline.

Beta-blockers not likely to cause depression yet may contribute to sleep disturbances Posted: 15 Mar 2021 08:01 AM PDT Depression was not more common in patients who used beta-blockers. The rate of discontinuing medications due to depression was the same for people taking beta-blockers compared to people taking other treatments. Sleep disorders, including insomnia and unusual dreams, may affect some patients taking beta-blockers.

Calls to poison centers about high-powered magnets increased by 444% after ban lifted Posted: 15 Mar 2021 08:01 AM PDT A recent study analyzed calls to U.S. poison centers for magnet exposures in children age 19 years and younger from 2008 through October 2019 to determine the impact of the CPSC rule and the subsequent lift of the ban.

Engineers combine AI and wearable cameras in self-walking robotic exoskeletons Posted: 15 Mar 2021 08:01 AM PDT Robotics researchers are developing exoskeletons and prosthetic legs capable of thinking and moving on their own using sophisticated artificial intelligence (AI) technology.
