A new scientific discovery has recorded how ghost currents and sediments can 'undo' the force of gravity. The new theory helps explain obscure events in which suspended sediment particles mysteriously move upward, not downward, on the slope of submarine canyons of the deep sea.

Experts have narrowed the group of individuals with prior allergies who should see an allergist before receiving a COVID-19 vaccine.

Engineers find that cancer cells exhibit a unique mode of migration on squishy materials, which are similar to biological tissues. In contrast, cell movement - a process central to cancer metastasis and other biological processes - is typically studied on very rigid materials.

Researchers have developed a topical drug that regenerates and restores the function of erectile nerves damaged by radical prostatectomy, the most common treatment for localized prostate cancer. The drug was tested in rats.

Refuting an earlier study, researchers found that epidural anesthesia, commonly administered for pain relief during labor, does not increase the risk for autism in children.

Researchers and physicians have found that early deaths of workers using methylene chloride paint strippers are on the rise. The solvent is widely used in paint strippers, cleaners, adhesives and sealants.

Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics. Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible before in a fraction of the time....

Immune responses in SARS-CoV-2 patients might provide only incomplete protection against SARS-CoV-2 variants from minks.

Various beetle species have gobbled through grain stores and weakened food production worldwide since ancient times. Now, researchers seek to exploit beetles' greatest strength against them -- their precisely regulated mechanism of balancing fluids.

Researchers used platinum and aluminum compounds to create a catalyst which enables certain chemical reactions to occur more efficiently than ever before. The catalyst could significantly reduce energy usage in various industrial and pharmaceutical processes. It also allows for a wider range of sustainable sources to feed the processes, which could reduce the demand for fossil fuels required by...

Using machine learning methods, researchers can predict the structure formation of functionalized molecules at the interfaces of hybrid materials. Now they have also succeeded in looking behind the driving forces of this structure formation.

A study has used long-term observations to investigate the complex interplay between fluctuations in the equatorial current system and variations in oxygen content. During the last 15 years the intensification of upper-ocean currents resulted in an increasing oxygen content in the equatorial region.

Scientists have sequenced ancient DNA from soil for the first time and the advance will transform what is known about everything from evolution to climate change. The findings have been described as the 'moon landings' of genomics because researchers will no longer have to rely on finding and testing fossils to determine genetic ancestry, links and discoveries - and it is thanks to Stone Age black...

For some patients, adding aspirin to a direct oral anticoagulant is an equation that rarely adds up.

A new gene therapy for one of the most common forms of congenital blindness was safe and improved patients' vision, according to initial data from a clinical trial.

Researchers have now analyzed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite electrodes is significantly lower than previously assumed. The study demonstrates ways to assess new photoelectrode materials more realistically.

University of Minnesota Medical School researchers revealed why some glioblastoma patients see exceptional benefits from chemotherapy and survive beyond expectations.

Treating people with Type 2 diabetes with a new once-a-week injectable insulin therapy proved to be safe and as effective as daily insulin injections, according to the results of two international clinical trials. The studies suggest that the once-weekly treatment could provide a convenient alternative to the burden of daily insulin shots for diabetes patients.

A new study finds a naturally occurring 'earthquake gate' that decides which earthquakes are allowed to grow into magnitude 8 or greater. Sometimes, the 'gate' stops earthquakes in the magnitude 7 range, while ones that pass through the gate grow to magnitude 8 or greater, releasing over 32 times as much energy as a magnitude 7.

A new study classifies different types of wildlife traffickers and sellers in two of Central Africa's growing urban centers, providing new insight into the poorly understood urban illegal wildlife trade.

New basic science research shows what happens to the development of abdominal aortic aneurysms when you inhibit JMJD3 through both genetics and pharmacology.

Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion.

New, detailed study of the Renland Ice Cap offers the possibility of modelling other smaller ice caps and glaciers with much greater accuracy than hitherto. The study combined airborne radar data to determine the thickness of the ice cap with on-site measurements of the thickness of the ice cap and satellite data. Researchers gathered data from the ice cap in 2015, and this work has now come to...

Middle-age and older people living in more disadvantaged neighborhoods -- areas with higher poverty levels and fewer educational and employment opportunities--had more brain shrinkage on brain scans and showed faster decline on cognitive tests than people living in neighborhoods with fewer disadvantages, according to a new study.
