From a professional standpoint, Nathan Hoot, MD, Ph.D., understands the value of medical research that leads to new, groundbreaking drugs in the treatment of rare diseases. And as an emergency medicine physician, he's familiar with adjusting ventilators and managing patients' airways. But the magnitude of these matters also weigh on Hoot personally -- as the father of a child with a rare genetic...
A paradox of food insecurity in wealthy countries is its association with excess weight. Now, a study finds that young adults in the United States who are food insecure not only are slightly more likely to be obese, they are significantly more likely to suffer from disorders associated with high body mass index, as well as obstructive airway diseases like asthma.
A recent Chinese mission has revealed more about the South Pole Aitken basinMost space rocks that hurtle towards Earth burn up in the atmosphere. The moon’s lack of atmosphere means it does not have the same protection, and consequently its surface is peppered with craters. The oldest and largest crater – a massive 2,000km across and 13km deep – sits at the far side of the moon. Known as the...
Physicists have found a way to measure the elusive quantum phase of electrons. This enables a new, better view of important phenomena used in photosensors or photovoltaics.
Nuclear abnormalities such as nuclear blebs and micronuclei have devastating consequences for the genetic material and are associated with cancer or ageing. Scientists now revealed that the epigenetic enzyme MOF is crucial for the morphological integrity of the mammalian nucleus. Moreover, the study characterized the epigenetic landscape of nuclear abnormalities and discovered a formerly unknown...
Deafness in early childhood is known to lead to lasting changes in how sounds are processed in the brain, but new research published today shows that even mild-to-moderate levels of hearing loss in young children can lead to similar changes.
Whether we're searching for Waldo or our keys in a room of clutter, we tap into a part of the frontal region of the brain when performing visual, goal-related tasks. Some of us do it well, whereas for others it's a bit challenging. One researcher set out to investigate why, and what specifically this part of the brain, called the pre-supplementary motor area, does during searching.
NASA's InSight lander on Mars has captured the low rumble of marsquakes and a symphony of other otherworldly sounds. InSight's seismometer has detected more than 100 events, but only 21 are considered strong marsquake candidates. The French seismometer is so sensitive it can hear the Martian wind as well as movements by the lander's robot arm and other mechanical "dinks and donks " as the team...
A team of New Jersey stroke researchers has linked recovery of reading and language competence with cerebral blood flow in the left reading network. Their findings may contribute to new approaches to identifying and treating reading deficits after stroke.
Putting power and potential behind gender equity in health care isn't just common sense. It's critical to the future of health, safety, and independence for us all as we age, so says the American Geriatrics Society in a new position statement. The statement outlines strategic objectives that can help us achieve a simple truth: 'When women rise, we all rise.'
The Royal Canadian Mint has issued a glow-in-the-dark coin that captures the eerie scene more than 50 years ago when what has been officially documented as a UFO crashed into the waters off Shag Harbour in southwestern Nova...
Four years after it was founded in Seattle, Relativity Space has landed its biggest infusion of capital to date — and says the $140 million investment will fully fund its drive to launch the world's first all-3D-printed rocket into orbit and enter commercial service in 2021. The company, now based in Los Angeles, was founded by two rocket engineers with connections to Jeff Bezos' Blue...
High levels of fructose in the diet inhibit the liver's ability to properly metabolize fat. This effect is specific to fructose. Indeed, equally high levels of glucose in the diet actually improve the fat-burning function of the liver.
A researcher has shown for the first time that the shape of a nanostructure has an effect on its ability to retain water. This has important ramifications for heat transfer, which is important when it comes to performance in small electronics.
Being in between living and non-living, viruses are, in general, strange. Among viruses, multipartite viruses are among the most peculiar -- their genome is not packed into one, but many, particles. Multipartite viruses primarily infect plants rather than animals. A recent article uses mathematical and computational models to explain this observation.
On 22 December 2018, a flank of the Anak Krakatau plunged into the Sunda strait between the Indonesian islands of Sumatra and Java, triggering a tsunami that killed 430 people. An international research team has now shown that the volcano produced clear warning signals before its collapse. The researchers recommend to use their study to improve monitoring of volcanoes.
Chemists have fabricated for the first time plasmonic color-switchable films of silver nanoparticles. Until now, such color changing of nanoparticles was mainly achieved in liquids, limiting their potential for practical applications. The technology has a number of applications: product authentication, color displays, signage, sensors, and information encryption.
Researchers have found it can significantly boost an existing polymer's ability to selectively remove carbon dioxide out of gas mixtures by first submerging the material in liquid water.
The new observation that strains of V. cholerae can be expelled into the environment after being ingested by protozoa, and that these bacteria are then primed for colonization and infection in humans, could help explain why cholera is so persistent in aquatic environments. The disease-causing bacteria are protected in the protozoan gut and ejected into the environment in membrane-bound expelled...
A new study suggests that transmission of a protozoan parasite from insects may also cause leishmaniasis-like symptoms in people. The parasite, however, does not respond to treatment with standard leishmaniasis drugs.
New research shows that female deep-sea anglerfish's bioluminescent bacteria -- which illuminate their 'headlamp' -- most likely come from the water.
Researchers have identified and confirmed the gene responsible for lutein esterification in bread wheat. The activity of this gene controls the timing of esterification in grain, which is related to storage and nutritional qualities of bread wheat and other grains.
Scientists have found that global tuna catches have increased over 1,000 per cent in the past six decades, fueled by a massive expansion of industrial fisheries.
Engineers have shown that the length of collagen fibers has a roll to play in the ability of normal cells to become invasive.
Two critical reviews examine the current status of biologic approaches for common shoulder and elbow problems. The authors discuss areas where the current evidence base is weak or controversial and recommend where further studies are required.

NASA telescopes have found thousands of exoplanets, some of which could host life. Scientists recently detected water vapor on a...
Chemical engineers have developed the first molecular motor that enables an eight-shaped movement.
New research suggests that patients with sepsis and septic lung injury could have a better chance of survival and recover more quickly when treated with vitamin C infusions. On average, the vitamin C group spent three fewer days in the ICU at day 28 and a week less in the hospital overall by day 60 than the placebo group.
People who live in rural counties in five states heavily affected by the opioid epidemic must drive longer distances to obtain methadone, a treatment for opioid addiction, compared to individuals from urban counties, say researchers. Their study suggests these long drive times in rural counties could be reduced by making methadone more accessible in primary care clinics.
On 22 December 2018, a flank of the Anak Krakatau volcano plunged into the Sunda strait between the Indonesian islands of Sumatra and Java, triggering a tsunami that killed 430 people. An international research team led by Thomas Walter of the German Research Centre for Geosciences GFZ in Potsdam has now shown that the volcano produced clear warning signals before its collapse. This was the result...
A weapon bacteria use to vanquish their competitors could be copied to create new forms of antibiotics, according to Imperial College London research.
Inspired by the unique and efficient swimming strategy of cephalopods, scientists developed an aquatic robot that mimics their form of propulsion.
Human activity churns out up to 100 times more planet-warming carbon each year as all the volcanoes on Earth, says a decade-long study released Tuesday.
Imagine a velvety, soft material that is extremely light, but also strong enough to stop a bullet. This is close to a description of ultra-high molecular weight polyethylene (UHMWPE), a super-plastic material commercially known as Dyneema or Spectra, which is already taking over from the para-aramid fibrous material, Kevlar, in e.g. bullet-proof jackets.
Volcanoes, colliding and spreading continental and oceanic plates, and other phenomena re-studied with innovative high-tech tools, provide important fresh insights to Earth's innermost workings, scientists say.
