A Chinese research team has developed an advanced imaging technique to achieve super-resolution microscopy at unprecedented speeds and with many fewer images. The new method should make it possible to capture processes in living cells at speeds not previously possible.
Glioblastoma currently has no cure. New treatments urgently needed
Powerful drug is 1,400 times more potent than current treatment against the brain tumor
Scientists applying to FDA for approval to test this novel treatment in patients with recurrent glioblastoma
PORTLAND, Ore. - A study of outpatient visits to health care providers in the United States during a one-year period suggests 18 percent of antibiotic prescriptions were written without a documented reason for doing so.
The findings, published today in BMJ, are important because they shed greater light on the frequency of antibiotic misuse outside of hospitals and other inpatient care facilities.
For viruses to multiply, they usually need the support of the cells they infect. In many cases, only in their host's nucleus can they find the machines, enzymes and building blocks with which they can multiply their genetic material before infecting other cells. But not all viruses find their way into the cell nucleus. Some remain in the cytoplasm and thus must be able to multiply their genetic material independently. To do so, they have to bring their own "machine park". An essential role in this process plays a special enzyme composed of various subunits: the RNA polymerase.
Using a computerised version of cognitive-behavioural therapy to treat depression in children and young adults has the potential to improve access to psychological therapies and reduce waiting lists, a new study suggests.
Cognitive behavioural therapy (CBT) - often known as talking therapy - is widely and effectively used in the mental health services to help people suffering from depression and anxiety. Reviews of CBT for adolescent depression have shown that it is effective and currently one of the main treatment options recommended for this age group
A team of researchers from the University of Georgia's Regenerative Bioscience Center has found that neural exosomes--"cargo" molecules within the nervous system that carry messages to the brain--can minimize or even avert progression of traumatic brain injury when used as part of a new cell-to-cell messaging technology.
The finding could result in the first delivery platform and regenerative treatment for TBI.
HOUSTON - (Dec. 12, 2019) - Molecular drills have gained the ability to target and destroy deadly bacteria that have evolved resistance to nearly all antibiotics. In some cases, the drills make the antibiotics effective once again.
Researchers at Rice University, Texas A&M University, Biola University and Durham (U.K.) University showed that motorized molecules developed in the Rice lab of chemist James Tour are effective at killing antibiotic-resistant microbes within minutes.
Since their invention more than 60 years ago, diamond anvil cells have made it possible for scientists to recreate extreme phenomena - such as the crushing pressures deep inside the Earth's mantle - or to enable chemical reactions that can only be triggered by intense pressure, all within the confines of a laboratory apparatus that you can safely hold in the palm of your hand.
Safe nuclear waste storage, new ways of generating and storing hydrogen, and technologies for capturing and reusing greenhouse gases are all potential spinoffs of a new study by University of Guelph researchers.
Published recently in Nature Scientific Reports, the study involved the first-ever use of antimatter to investigate processes connected to potential long-term storage of waste from nuclear reactors, says lead author and chemistry professor Khashayar Ghandi.
New research has revealed that Australia's oldest flowering plants are 126 million years old and may have resembled modern magnolias, buttercups and laurels.
Undertaken by University of Melbourne palynologist, Dr Vera Korasidis, the study also found that Australia's first blooms got their foothold in 'high southern latitude' regions like the Otway and Gippsland ranges.
Caribou, the North American cousin of reindeer, migrate farther than any terrestrial animal. They can cover thousands of miles as they move between winter feeding grounds and summer calving grounds. But many caribou herds are in decline as the warming climate changes much of the landscape they depend on. Inedible shrubs are rapidly encroaching on the tundra, and more frequent forest fires and disease are destroying the trees that provide caribou with lichen for food.
The NASA/ESA Hubble Space Telescope has once again captured comet 2I/Borisov streaking through our solar system on its way back into interstellar space. At a breathtaking speed of over 175 000 kilometres per hour, Borisov is one of the fastest comets ever seen. It is only the second interstellar object known to have passed through the Solar System.
SASKATOON--The heady aroma of magnolia blossoms and lotus flowers might have wafted to your nostrils if you had gone for a walk 56 million years ago in the lush green forest which covered Canada's northernmost islands.
Now covered in ice and snow, present-day Ellesmere and Axel Heiberg islands in Nunavut were once home to a vibrant, temperate forest, according to fossil research just published by University of Saskatchewan (USask) scientists.
A new study by researchers at the Columbia Center for Children's Environmental Health (CCCEH) at Columbia Mailman School of Public Health is the first to compile the estimated per-case costs of six childhood health conditions linked to air pollution--estimates that can be incorporated into benefits assessments of air pollution regulations and climate change mitigation policies. Results appear in the journal Environmental Research.
Getting premature babies to breathe without assistance has always been a stressful mission for doctors. But by carefully ventilating babies with 100% oxygen researchers have found a way to jump-start these first independent moments.
Spontaneous breathing at birth is critical so that doctors can avoid using invasive respiratory interventions on fragile newborns. But hypoxia - a lack of adequate oxygen supply to the body - is a huge inhibitor of natural breathing and a particularly large risk for premature babies.
