BUFFALO, N.Y. -- Graphene excels at removing contaminants from water, but it's not yet a commercially viable use of the wonder material.
That could be changing.
In a recent study, University at Buffalo engineers report a new process of 3D printing graphene aerogels that they say overcomes two key hurdles -- scalability and creating a version of the material that's stable enough for repeated use -- for water treatment.
URBANA, Ill. - Before humans can benefit from new drug therapies and nutritional additives, scientists test their safety and efficacy in animals, typically mice and rats. But, as much as they've done for biomedical research, rodents aren't always the best research model for studies on neonatal brain development and nutrition. That's where pigs can play an important role.
University of Illinois researchers say the domestic pig is ideal for these studies because their brain size, rate of development, and digestive system are excellent analogues for human newborns.
La Jolla, CA--The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape--and biologists are taught that defined shape dictates the protein's destined function. Tens of thousands of singular shapes drive the tens of thousands of needed functions.
New research by a team at Resources for the Future (RFF) has found that at least 27% of new pests in the United States were initially detected by members of the general public. The study, which was published today in the journal Conservation Science and Practice, seeks to understand who is identifying new invasive species that make their way into the United States.
Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials called "quasicrystals" with custom magnetic or electrical properties.
The research is published in Physical Review Letters.
The coronavirus pandemic has led researchers to switch gears or temporarily abandon projects due to health protocols or not being able to travel. But for Patrick Keys and Elizabeth Barnes, husband and wife scientists at Colorado State University, this past year led to a productive research collaboration.
Geneva, 15th April 2021 - When it was shown launching out of the sea to snatch birds from the air in the first episode of the BBC's Blue Planet II, the Seychelles giant trevally, or 'karang ledan' as it is called in Creole, became world-famous. Typically eating fish, not birds, this reef predator is critical for maintaining healthy balanced ecosystems. 'The giant trevally is a popular, sought-after prize fish in Seychelles, particularly in the big-game sportfishing industry. Seychelles has a reputation for being one of the best trevally destinations in the world.
PHILADELPHIA-- Humans have a uniquely high density of sweat glands embedded in their skin--10 times the density of chimpanzees and macaques. Now, researchers at Penn Medicine have discovered how this distinctive, hyper-cooling trait evolved in the human genome.
If global warming continues unchecked, summer monsoon rainfall in India will become stronger and more erratic. This is the central finding of an analysis by a team of German researchers that compared more than 30 state-of-the-art climate models from all around the world. The study predicts more extremely wet years in the future - with potentially grave consequences for more than one billion people's well-being, economy, food systems and agriculture.
Female nurses are roughly twice as likely to commit suicide than the general female population and 70% more likely than female physicians, according to a University of Michigan study examining suicide among physicians and nurses.
Bruising caused by physical abuse is the most common injury to be overlooked or misdiagnosed as non-abusive before an abuse-related fatality or near-fatality in a young child. A refined and validated bruising clinical decision rule (BCDR), called TEN-4-FACESp, which specifies body regions on which bruising is likely due to abuse for infants and young children, may improve earlier recognition of cases that should be further evaluated for child abuse. Findings were published in the journal JAMA Network Open.
A team of scientists, led by the University of Bristol, with colleagues from Goethe University, Frankfurt, has found the first evidence for ancient honey hunting, locked inside pottery fragments from prehistoric West Africa, dating back some 3,500 years ago.
Reconfigurable materials can do amazing things. Flat sheets transform into a face. An extruded cube transforms into dozens of different shapes. But there's one thing a reconfigurable material has yet to be able to change: its underlying topology. A reconfigurable material with 100 cells will always have 100 cells, even if those cells are stretched or squashed.
A wide range of objects, from biological cells to integrated circuits, are tomographically imaged to identify their interior structures. Volumetric reconstruction of the objects' interiors is of practical implications, for instance, quantitative phase imaging of the cells and failure analysis of the circuits to validate their designs. Limiting the tomographic angular range is often desirable to reduce the time of radiation exposure and avoid any devastating effects upon the samples, or even unavoidable due to the structure of objects like in the case of tomosynthesis for mammography.
Common ragweed is an annual plant native to parts of the United States and southern Canada. It's an invasive species that has spread to Europe. An important agricultural weed, this plant is particularly well-adapted to living at roadsides, and there are several theories why.
