Published Preliminary study shows potential of Manuka honey as a nutraceutical for breast cancer
(via sciencedaily.com) Original source A new study found that Manuka honey could potentially be an alternative, natural option for breast cancer prevention and treatment -- particularly for estrogen receptor (ER)-positive breast cancer, the most common subtype of breast cancer that accounts for about 70-80% of all breast cancer cases.
Published Revolutionizing thermoelectric technology: Hourglass-shaped materials achieve a 360% efficiency boost
(via sciencedaily.com) Original source A groundbreaking technology has been unveiled that improves the efficiency of thermoelectric materials, which are key in converting waste heat into electricity, by altering their geometry to resemble an hourglass. Unlike previous research that solely depended on the material properties of thermoelectric substances, this new approach is expected to have widespread applications in thermoelectric power generation.
Published Research provides a roadmap for improving electrochemical performance
(via sciencedaily.com) Original source A study expands understanding on how electrons move through the conductive parts of complex fluids found in electrochemical devices such as batteries. This work can help overcome existing knowledge gaps for engineers seeking to improve the performance of these devices.
Published Probiotics during pregnancy shown to help moms and babies
(via sciencedaily.com) Original source Giving probiotics to pregnant mice can enhance both the immune system and behavior of the mothers and their offspring.
Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Zebrafish use surprising strategy to regrow spinal cord
(via sciencedaily.com) Original source A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.
Published Surprise finding in study of environmental bacteria could advance search for better antibiotics
(via sciencedaily.com) Original source Researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's 'envelope' or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.
Published Physicists throw world's smallest disco party
(via sciencedaily.com) Original source A new milestone has been set for levitated optomechanics as a group of scientists observed the Berry phase of electron spins in nano-sized diamonds levitated in vacuum.
Published Scientists create material that can take the temperature of nanoscale objects
(via sciencedaily.com) Original source Scientists recently discovered a one-dimensional nanoscale material whose color changes as temperature changes.
Published Beige fat cells with a 'Sisyphus mechanism'
(via sciencedaily.com) Original source A new class of fat cells makes people healthier. The cells consume energy and produce heat through seemingly pointless biochemical reactions.
Published New mechanism of action kills cancer cells
(via sciencedaily.com) Original source Conventional cancer drugs work by triggering apoptosis, that is programmed cell death, in tumor cells. However, tumor cells have the ability to develop strategies to escape apoptosis, rendering the drugs ineffective. A research team now describes a new mechanism of action that kills cancer cells through ferroptosis.
Published Exploring the structures of xenon-containing crystallites
(via sciencedaily.com) Original source Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow sufficiently large crystals that contain noble gases, some of their structures -- and therefore functions -- remain elusive. Now, researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds.
Published A ketogenic diet could improve the response to pancreatic cancer therapy
(via sciencedaily.com) Original source Scientists have discovered a way to get rid of pancreatic cancer in mice by putting them on a high fat, or ketogenic, diet and giving them cancer therapy.
Published Exciting advance in stem cell therapy
(via sciencedaily.com) Original source A new technique for mechanically manipulating stem cells could lead to new stem cell treatments, which have yet to fulfill their therapeutic potential.
Published Scientists achieve more than 98% efficiency removing nanoplastics from water
(via sciencedaily.com) Original source Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.
Published Surprising insight into cancer comes from unique plant species that find different solutions to evolutionary challenges
(via sciencedaily.com) Original source A study has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into aggressive forms of cancer.
Published Rewriting the evolutionary history of critical components of the nervous system
(via sciencedaily.com) Original source A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
Published Breakthrough in nanotechnology: Viewing the invisible with advanced microscopy
(via sciencedaily.com) Original source Scientists have made a groundbreaking discovery in the field of nanotechnology. They have developed a novel microscopy method that allows for the unprecedented visualization of nanostructures and their optical properties.
Published Starvation and adhesion drive formation of keratinocyte patterns in skin
(via sciencedaily.com) Original source Cell-cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion researchers find.
Published Study reveals oleoyl-ACP-hydrolase underpins lethal respiratory viral disease
(via sciencedaily.com) Original source Respiratory infections can be severe, even deadly, in some individuals, but not in others. Scientists have gained new understanding of why this is the case by uncovering an early molecular driver that underpins fatal disease. Oleoyl-ACP-hydrolase (OLAH) is an enzyme involved in fatty acid metabolism. A study shows that OLAH drives severe disease outcomes.
