Researchers have now developed a non-invasive method to help diagnose celiac disease and which uses saliva. This research has shown that it is possible to considerably reduce the number of endoscopies, which are currently carried out via a non-invasive method of diagnosis.
Clinicians frequently order preoperative urinalyses for patients scheduled to undergo many common procedures. A new study finds that nearly nine out of 10 of preoperative urinalyses are unnecessary. Overuse of low-value screening test wastes money, can harm patients and may contribute to the growing problem of antibiotic resistance.
Six weeks of physical exercise led to changes in the epigenetic information of skeletal muscle cells in young men. These changes took place in areas of the genome that have been linked to disease. Scientists say their research shows how exercise remodels DNA in skeletal muscle, so that new signals are established to keep the body healthy.
In March 2020, 83,000 New Jersey residents who had been ineligible to vote became eligible when a new law took effect restoring voting rights for people on parole or probation who had previously been convicted of felonies.

Captured by the Copernicus Sentinel-3 mission on 30 July 2021, this image shows smoke billowing from several fires along the southern coast of Turkey. Turkey has been battling deadly wildfires since last week. Over the weekend, tourists and local residents had to be evacuated from Bodrum and Marmaris, with some fleeing by boat as the flames crept closer to the shoreline. Southeast Europe is curren
After so many smoke-filled summers and record-setting burns, residents of Western North America are no strangers to wildfires. Still, many questions are circulating about why forest fires are becoming larger and more severe—and what can be done about it.
A lot of people have noticed that the self-driving car revolution has been…delayed. For the last decade predictions of when the technology would be ready for mass adoption were converging on the 2020s, beginning early in the decade. In this 2010 article , the prediction was – at least 8 years. Also , “US Secretary of Transportation Anthony Foxx declared in 2016 that we’d have fully autonomous car
New research suggests how to conserve rough-nosed horned lizards, which live only in Sri Lankan rainforests. Characterized by the prominent horn in males, rough-nosed horned lizards ( Ceratophora aspera ) live in moist, humid microhabitats in rainforests and palm groves. These lizards are a good example of the consequences of rainforest habitat destruction, climate change, and the pet trade, as t
As communism imploded in 1989, the American political scientist Francis Fukuyama asked if liberal democracy was "the end of history," being the form all societies were destined to take. The past decades have suggested not. Illiberal democracies and hybrid democratic-authoritarian regimes continue to emerge.
You may have seen the before-and-after-lockdown photos of major cities that appear to show dramatic changes in air quality. In one, the India Gate war memorial in New Delhi is barely visible amid the smog. Then, during lockdown, it's clearly visible in its red Bharatpur stone grandness.
Over the past year, a noticeable portion of MAGA world has been removed from mainstream social-media platforms or inspired to decamp to newer, more permissive sites such as Parler, Gab, MeWe, and Rumble. These alternative platforms are not known for their tough content moderation or for providing a great user experience; however, they are not exactly the dark web, either. You or I can easily look
Many scientists are likely to be invited for media appearances in the run up to COP26, the international negotiations on global heating that will take place in Glasgow in November 2021. Journalists will ask climate scientists to help place the talks in context and to discuss the value of particular options for reducing emissions, or to explain how climate change may have contributed to particular
The human brain holds the secret to our unique personalities. But did you know that it can also form the basis of highly efficient computing devices? Researchers from Nagoya University, Japan, recently showed how to do this, through graphene-diamond junctions that mimic some of the human brain's functions.
New research may clarify how much hydration is necessary during different stages of pregnancy. Water needs increase during pregnancy to support fetal development and maternal health, however little is known about the relationship between hydration status and outcomes on both mother and child. A study recently examined the hydration status of pregnant women, the effect of a behavioral intervention
Wales could face public water supply challenges and lower hydro power generation potential in the future according to new research. The findings of a recently published study conducted by Bangor University researchers, as part of the ERDF funded Dŵr Uisce project, shows that water availability in Wales will become more seasonal under future climate change.
The more we learn about the past, the more we come to understand that ancient societies share some striking similarities to our own. From the first waves of migration out of Africa to the Ancestral Pueblo, the peoples of the past created art, migrated to new lands, fought wars, raised families, and exploited natural resources for housing, food, and tools—just like we do. With the help of a powerfu
Research from the School of Biosciences and the University of Manchester has uncovered an essential mechanism coordinating the processes of cell division and adhesion within humans. This discovery has profound potential for advancing understanding of cell adhesion signaling in cancerous tumor progression and metastasis.

In addition to being freighted with hardship, the American immigrant experience is occasionally hilarious. Misunderstandings, wonky translations, and cultural exchanges gone wrong are inevitable fodder for comedy—the question is who gets to enjoy the punch line. In her book Minor Feelings , the Korean American poet Cathy Park Hong describes humor as potentially liberating for the Asian immigrant,
More than 5,000 kilometres beneath us, Earth's solid metal inner core wasn't discovered until 1936 . Almost a century later, we're still struggling to answer basic questions about when and how it first formed. These aren't easy puzzles to solve. We can't directly sample the inner core, so the key to unravelling its mysteries lies in collaboration between seismologists , who indirectly sample it w

Panpsychists look at the many rungs on the complexity ladder of nature and see no obvious line between mind and no-mind. Illustration by Yurchanka Siarhei / Shutterstock Last year, the cover of New Scientist ran the headline, “Is the Universe Conscious?” Mathematician and physicist Johannes Kleiner, at the Munich Center for Mathematical Philosophy in Germany, told author Michael Brooks that a mat
How will we ever get to a world where drones can make deliveries or even transport people like you see in futuristic pictures? Been thinking about this for a while just because it seems like a huge threat to every country’s national security. Would it all have to be mapped like airplanes?Not sure if this is the right sub but I’d love to hear anyone’s thoughts… thx submitted by /u/jarovo [link] [c
Last month, billionaire after billionaire hopped into spacecraft to reach the final frontier. Shivani Dave speaks to Robert Massey, the deputy executive director at the Royal Astronomical Society, to understand what, if any, positives might come from what has been called ‘the billionaire space race’, or if the money and resources spent on space exploration should be redistributed to focus on the c
A new study points to a strong 'edge effect' in marine protected areas (MPAs), sharply reducing by 60 percent the fish population living up to 1 – 1.5 km within the MPA. This significantly diminishes the effectiveness of the MPA. Most of the damage stems from fishing pressure around the MPAs.
Researchers have developed a simplified mathematical model (step-loading model, SLM) that unifies two earlier mechanisms to describe the velocity jump in crack propagation. Through SLM, they showed that the near-tip mechanical behavior observed from one analysis is derived from the dynamic glass transition at the crack tip described in another proposal, thus merging the two distinct analyses, and
This month is IPCC month – the Sixth Assessment Report from Working Group 1 is out on Monday August 9. We’ll have some detailed comments once it’s out, but in the meantime, feel free to speculate widely (always considering that IPCC is restricted to assessing existing literature…). Open thread – please stick to climate science topics. The post first appeared on RealClimate .
When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. Researchers observed such offsets in both eyes of 20 healthy subjects, and speculate that the underlying fixation behavior improves overall vision.
Researchers thought 30 years ago that they just introduced some Glanville fritillary butterfly larvae on a small island in the Åland islands, Finland. Little did they know that within the butterfly larvae there nested two other insect species and a bacterial symbiont. This created a unique opportunity to study how a local accidental introduction of insects can affect the dynamics and genetics of t
