- 20/8/26 23:56
A clinical trial at four pediatric diabetes centers in the United States has found that a new artificial pancreas system -- which automatically monitors and regulates blood glucose levels -- is safe and effective at managing blood glucose levels in children as young as age six with type 1 diabetes.
Water efficiency achievable throughout U.S. without decrease in economic activity
- ScienceDaily
- 20/8/26 23:56
Researchers have looked at how much water conservation can readily and affordably be achieved in each region and industry by looking at what conservation measures were already working and considering how much water is being used.
Progress toward a treatment for Krabbe disease
- ScienceDaily
- 20/8/26 23:56
The inherited disease, which typically kills children before their second birthday, has no cure, but a new study in a canine model offers hope for an effective gene therapy with lasting results.
Thermodynamics of computation: A quest to find the cost of running a Turing machine
- ScienceDaily
- 20/8/26 23:56
Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work exploring the energetic costs of computation within the context of Turing machines.
Damage from whopper hurricanes rising for many reasons
A destructive storm is rising from warm waters. America and the world are getting more frequent and bigger multibillion dollar tropical catastrophes like Hurricane Laura, which is menacing the U.S. Gulf Coast, because of a combination of increased coastal development, natural climate cycles, reductions in air pollution and man-made climate change, experts say. It's a mess at least partially of...
Rigid social distancing rules for COVID-19 based on outdated science, say experts
- ScienceDaily
- 20/8/26 22:50
Rules which stipulate a single specific physical distance (1 or 2 metres) between individuals to reduce the spread of covid-19 are based on outdated science and experiences of past viruses, say researchers in a new article.
Interventions stem antibiotic prescribing rates in telemedicine
- ScienceDaily
- 20/8/26 22:50
Two different interventions both worked to significantly reduce the rate of inappropriate antibiotic prescriptions made by physicians in a telemedicine practice, a new study shows. The finding could offer a new way to stem the growing problem of antibiotic resistance, particularly as telemedicine grows due to the ongoing COVID-19 pandemic.
Placenta can indicate how body responds to opioids during pregnancy
- ScienceDaily
- 20/8/26 22:50
Scientists have discovered possible biological markers that they hope could one day help identify the presence of an opioid use disorder during human pregnancy.
What is cerebral venous thrombosis? Study finds blood clot condition on the rise
- ScienceDaily
- 20/8/26 22:13
Cerebral venous thrombosis (CVT) occurs when a blood clot forms in one of the veins in the brain, preventing blood from draining out of the brain. A new analysis has found that the incidence of CVT in the United States is higher than previously reported and has increased over time.
U.S. political parties become extremist to get more votes
- ScienceDaily
- 20/8/26 22:13
New mathematical modeling shows that U.S. political parties are becoming increasingly polarized due to their quest for voters -- not because voters themselves are becoming more extremist.
Neutralizing antibodies appear to protect humans from coronavirus infection
- ScienceDaily
- 20/8/26 22:13
A Seattle fishing vessel that departed port in May returned 18 days later with an unusual haul: the first human evidence that neutralizing antibodies provide protection from reinfection by SARS-CoV-2.
Fires 'poisoning air' in Amazon: study
Rampant fires in the Amazon are "poisoning the air" of the world's biggest rainforest, causing a sharp rise in respiratory emergencies in a region already hit hard by COVID-19, said a study published Wednesday.
How low did it go? Scientists calculate Earth's Ice Age temperatures
Guided by ocean plankton fossils and climate models, scientists have calculated just how cold it got on Earth during the depths of the last Ice Age, when immense ice sheets covered large parts of North America, South America, Europe and Asia. The average global temperature during the period known as the Last Glacial Maximum from roughly 23,000 to 19,000 years ago was about 46 degrees Fahrenheit...
Native desert bighorn sheep in ecologically intact areas are less vulnerable to climate change
In the American Southwest, native desert bighorn sheep populations found in landscapes with minimal human disturbance, including several national parks, are less likely to be vulnerable to climate change, according to a new study led by Oregon State University.
New observations of black hole devouring a star reveal rapid disk formation
- ScienceDaily
- 20/8/26 21:27
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the light from these 'tidal disruption events' (TDEs) for clues to the feeding behavior of the supermassive black holes lurking at the centers of galaxies, and new observations help resolve crucial...
Study rules out dark matter destruction as origin of extra radiation in galaxy center
The detection more than a decade ago by the Fermi Gamma Ray Space Telescope of an excess of high-energy radiation in the center of the Milky Way convinced some physicists that they were seeing evidence of the annihilation of dark matter particles, but a team led by researchers at the University of California, Irvine has ruled out that interpretation.
Meteorite strikes may create unexpected form of silica
- ScienceDaily
- 20/8/26 21:13
New research examining the crystal structure of the silica mineral quartz under shock compression is challenging longstanding assumptions about this ubiquitous material.
Researchers unravel two mysteries of COVID-19
- ScienceDaily
- 20/8/26 21:13
In one study, researchers have identified six molecules that can be used as biomarkers to predict how severely ill a patient will become. In another study, they reveal a new mechanism causing blood clots in COVID-19 patients and potential ways to treat them.
Study rules out dark matter destruction as origin of extra radiation in galaxy center
- ScienceDaily
- 20/8/26 21:13
Through an analysis of the Fermi data and an exhaustive series of modeling exercises, researchers were able to determine that an observed excess of gamma rays could not have been produced by what are called weakly interacting massive particles, most popularly theorized as the stuff of dark matter.
Tethering together type 2 diabetes drugs increases efficacy of combination therapy
- ScienceDaily
- 20/8/26 21:13
Biomedical engineers have shown that the effectiveness of a two-pronged type 2 diabetes treatment increases when the drugs are linked by a heat-sensitive tether rather than concurrently administered. The combination molecule forms a gel-like depot under the skin that slowly releases the drug. These findings suggest that this approach to combination drug design could be applied to disease therapies...

In the American Southwest, native desert bighorn sheep populations found in landscapes with minimal human disturbance, including several national parks, are less likely to be vulnerable to climate change.
18 whales die in Mauritius stranding
Eighteen melon-headed whales washed up on the shores of Mauritius on Wednesday, the country's fisheries minister said, dismissing any link to a devastating oil spill earlier this month.
Fighting mosquito-borne diseases... with mosquitoes
For decades, researchers have scratched their heads over how to combat deadly mosquito-borne diseases such as dengue fever.
Laura strengthens into 'extremely dangerous' Category 4
Laura strengthened Wednesday into a menacing Category 4 hurricane, raising fears of a 20-foot storm surge that forecasters said would be "unsurvivable" and capable of sinking entire communities. Authorities implored coastal residents of Texas and Louisiana to evacuate and worried that not enough had fled.
Testing traps to control lovely but destructive lionfish
The quest is on for a better way to kill beautiful but brutally destructive lionfish than shooting them one by one with spearguns.
