Scientists have developed the first practical artificial leaf that can mimic photosynthesis, converting sunlight and water into electricity. The device is made of inexpensive materials and works stably, with the potential to provide affordable power for homes in developing countries.
A study identified three critical steps to transform normal blood cells into leukaemic ones, each subverting a different cellular process. The researchers found that NPM1 mutation is a key event in acute myeloid leukaemia development and can cooperate with other mutations to cause the disease.
Scientists have discovered a way to extinguish fires using electrical waves, which could provide a new genre of fire-fighting devices. The technology could allow firefighters to put out fires remotely and save water, making it a promising solution for fighting fires in enclosed spaces.
A study by Massachusetts General Hospital and Brown University found that seizures begin with diverse neuronal activity, rather than synchronized activity. The researchers observed pre-seizure changes in neuronal activity and detected changes before seizures began in most patients.
Scientists have established a strong link between nicotine and diabetes complications, finding that concentrations of nicotine similar to those found in smoker's blood raise levels of HbA1c by up to 34%. This discovery may encourage patients with diabetes to quit smoking and has implications for the use of nicotine-replacement therapy.
Research on Diffuse Interstellar Bands (DIBs) in distant galaxies led to the discovery of Buckminsterfullerene, a new form of carbon that gave birth to nanotechnology. The study highlights the potential benefits of funding research with no obvious immediate use.
Scientists have discovered a previously unknown type of axonal degeneration called focal axonal degeneration (FAD), which is responsible for damage to nerve cells in multiple sclerosis. FAD can be reversed if recognized and treated early, suggesting a potential target for therapeutic intervention.
Scientists have developed a process to turn meat and bone meal, once destined for landfills due to a government ban, into partially biodegradable plastic. The new material is durable and requires no raw materials from oil or natural gas.
A new study by Joe Vinson ranks walnuts as the No. 1 nut in terms of healthful antioxidants, with nearly twice as much antioxidants as other commonly consumed nuts. Walnuts contain a combination of high-quality protein, vitamins, minerals, dietary fiber and are dairy- and gluten-free.
Researchers at Scripps Research Institute have made a groundbreaking discovery about the structure of the MRN DNA repair complex, revealing its powerful molecular motor workings. The finding has implications for designing non-toxic drugs to treat disorders such as cancer and cystic fibrosis.
The American Chemical Society symposium 'Hollywood Chemistry' highlighted the importance of scientists advising on the accuracy of science-based TV shows and movies. Chemist advisers like Donna Nelson from Breaking Bad discussed ways to improve scientific portrayal in media, while producers shared experiences and lessons learned from p...
The ACS National Meeting featured symposia on nanotechnology, bioactives, and regenerative medicine, including sessions on cell-based therapeutics and novel biomaterials for tissue engineering. The meeting also highlighted innovative approaches to address global energy demands through biotechnology.
The study provides geological evidence to support the idea that the first solid material in the Solar System was fragile and extremely porous. Researchers analyzed an asteroid fragment and found that it had been subjected to shocks in space, possibly during periods of turbulence, which compacted the rock into a harder state.
Scientists report on a new material called nano-bricks that combines montmorillonite clay with polymer materials to create an eco-friendly, transparent coating. The coating can improve the shelf life of foods and beverages by slowing gas loss and preventing spoilage, making it a potential alternative to current packaging materials.
Researchers at the University of Utah discovered that invisible infrared light can activate rat heart cells and toadfish inner-ear cells, sparking potential breakthroughs in cochlear implants for deafness. The study also raises possibilities for optical pacemakers that use infrared signals instead of electrical signals.
Researchers have developed an artificial plasmid coding for Sindbis virus replicase genes that causes regression of lung and melanoma tumors in mice. The plasmid forces cells to produce double-stranded RNA, leading to cell death and activation of immune responses.
Scientists have developed stronger, lighter, and more sustainable automotive plastics by harnessing the power of plant-based nano-cellulose fibers. These innovative materials are set to revolutionize car production, reducing weight and improving fuel efficiency.
A new study published in Nature suggests that biodiversity can evolve in complex environments where previously thought to be impossible. Researchers found that both 'fit' and 'unfit' species can coexist indefinitely due to trade-offs between growth rate and efficiency.
