Why you shouldn’t declaw tigers or other big cats
Researchers looked at the effects of declawing on larger cat species and found that declawing disproportionately impacts their muscular capabilities as compared to their smaller brethren.
Modifications to amino acids in sperm could be behind infertility
Researchers are delving into the molecular-level details of sperm formation, with a particular focus on how abnormalities in this process might lead to male-factor infertility.
New study links brain waves directly to memory
Simply remembering events can trigger brain rhythms, even more so than when people are experiencing the actual event, says a new study. The findings could lay foundations for cognitive impairment therapy and help improve memory.
Researchers identify two new subtypes of HPV-associated head and neck cancers
Researchers have identified two subtypes of human papillomavirus positive head and neck cancers, giving them a better glimpse into why some patients respond better to treatment than others.
Lignin separation method could make renewable material profitable
A novel method to extract lignin could help spin wheat straw into gold. Lignin produced using the new method was color-neutral, odorless and homogenous, an advance that could make this carbon-neutral material a more viable candidate for development of …
Engineers create an energy-storing supercapacitor from ancient materials
Engineers have created a ‘supercapacitor’ made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive sys…
How flies develop sight: Scientists use single-cell sequencing to identify cell types in the visual system
Researchers have discovered new cell types in the visual system of flies, made possible by their creation of a tool that finds and labels neurons during development. The study combines single-cell sequencing data with a novel algorithm to identify pair…
How to distinguish slow and fast earthquakes
Slow earthquakes are slow-slip phenomena that last many days or months, and you barely notice them. In 2007, researchers proposed how the magnitude and duration of earthquakes vary, which can help differentiate slow and fast earthquakes. Seismologists …
Sun ‘umbrella’ tethered to asteroid might help mitigate climate change
Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach — a solar shield to reduce the amount of sunlight hitting Earth, combined with a tether…
Researchers discover method to overcome antimicrobial resistance
Researchers have described a new class of molecules that inhibit efflux pumps so that antiboitics remain effective.
