An experimental drug rapidly shrinks most tumors in a mouse model of human breast cancer, researchers report in the Proceedings of the National Academy of Sciences. When mice were treated with the experimental drug, BHPI, the tumors immediately stopped growing and began shrinking rapidly.
Using high-performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion people on it by 2050, researchers report in Cell.
Researchers from the Univ. of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.
A new molecule-making machine could do for chemistry what 3-D printing did for engineering: Make it fast, flexible and accessible to anyone. Chemists at the Univ. of Illinois built the machine to assemble complex small molecules at the click of a mouse, like a 3-D printer at the molecular level. The automated process has the potential to greatly speed up and enable new drug development and other technologies that rely on small molecules.
With more than five times the thermal conductivity of copper, diamond is the ultimate heat spreader. But the slow rate of heat flow into diamond from other materials limits its use in practice. In particular, the physical process controlling heat flow between metals and diamond has remained a mystery to scientists for many years.
A new drug that prompts cancer cells to self-destruct while sparing healthy cells is now entering phase I clinical trials in humans. The drug, called PAC-1, first showed promise in the treatment of pet dogs with spontaneously occurring cancers, and is still in clinical trials in dogs with osteosarcoma.
When exposed to nitrogen fertilizer over a period of years, nitrogen-fixing bacteria called rhizobia evolve to become less beneficial to legumes, researchers report in a new study. These findings, reported in Evolution, may be of little interest to farmers, who generally grow only one type of plant and can always add more fertilizer to boost plant growth.
Researchers at the Univ. of Illinois at Urbana-Champaign have developed a unique single-step process to achieve 3-D texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3-D texturing, or "crumpling," allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.
The second law of thermodynamics tells us that all systems evolve toward a state of maximum entropy, wherein all energy is dissipated as heat, and no available energy remains to do work. Since the mid-20th century, research has pointed to an extension of the second law for nonequilibrium systems.
Seismic waves are helping scientists to plumb the world’s deepest mystery: the planet’s inner core. Thanks to a novel application of earthquake-reading technology, a research team at the Univ. of Illinois and colleagues at Nanjing Univ. in China have found that the Earth’s inner core has an inner core of its own, which has surprising properties that could reveal information about our planet.
Two new drug compounds appear to be effective in treating endometriosis, a disorder that, like MS, is driven by estrogen and inflammation, scientists report in Science Translational Medicine. The researchers hope to eventually use the new compounds and others like them to treat a variety of disorders linked to estrogen signaling and inflammation.
People who have upbeat outlooks on life have significantly better cardiovascular health, suggests a new study that examined associations between optimism and heart health in more than 5,100 adults. Participants’ cardiovascular health was assessed using seven metrics: blood pressure, body mass index, fasting plasma glucose and serum cholesterol levels, dietary intake, physical activity and tobacco use.
Stroke victims could have more time to seek treatment that could reduce harmful effects on the brain, thanks to tiny blobs of gelatin that could deliver the medication to the brain noninvasively. Univ. of Illinois researchers found that gelatin nanoparticles could be laced with medications for delivery to the brain, and that they could extend the treatment window for when a drug could be effective.
Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo: the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique developed by researchers can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.
Scientists have created an app that brings molecules to life in a handheld device. Through the app, people can use up to eleven fingers to examine in great detail more than 350 molecules.
Researchers at the Univ. of Illinois at Urbana-Champaign have figured out how to reverse the characteristics of a key bonding material—polyurea—providing an inexpensive alternative for a broad number of applications, such as drug delivery, tissue engineering and packaging.
The house mouse, stickleback fish and honey bee appear to have little in common, but at the genetic level these creatures respond in strikingly similar ways to danger, researchers report. When any of these animals confronts an intruder, the researchers found, many of the same genes and brain gene networks gear up or down in response.
Farmers interested in bioenergy crops now have a resource to help them determine which kind of bioenergy crop would grow best in their regions and what kind of harvest to expect. Researchers at the Univ. of Illinois have published a study identifying yield zones for three major bioenergy crops.
When munched by grazing animals (or mauled by scientists in the laboratory), some herbaceous plants overcompensate, producing more plant matter and becoming more fertile than they otherwise would. Scientists say they now know how these plants accomplish this feat of regeneration. They report their findings in Molecular Ecology.
Tiny, thin microtubes could provide a scaffold for neuron cultures to grow so that researchers can study neural networks, their growth and repair, yielding insights into treatment for degenerative neurological conditions or restoring nerve connections after injury. Researchers created the microtube platform to study neuron growth.
A common perception, especially outside the university classroom, is that teaching and research are two separate domains, with little overlap. That’s not the reality, however, for many Univ. of Illinois faculty. For these faculty members, “there is an active and dynamic link” between the two.
In spite of the broad scientific consensus about its existence, global warming remains a contentious public policy issue. Yet it’s also an issue that requires a public consensus to support policies that might curb or counteract it. According to research, the task of educating the public about climate change might be made easier or more difficult depending on their perception of short-term versus long-term temperature changes.
Astronomers have caught their first glimpse of the invisible magnetic fields that sculpt solar systems. Looking at a bright, nearby baby star and the dust swirling in its cradle, astronomers from the Univ. of Illinois and six collaborating institutions were able to make out the shape of the magnetic field surrounding the star.
Researchers report in Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.
River beds, where flowing water meets silt, sand and gravel, are critical ecological zones. Yet how water flows in a river with a gravel bed is very different from the traditional model of a sandy river bed, according to a new study that compares their fluid dynamics. The findings establish new parameters for river modeling that better represent reality, with implications for field researchers and water resource managers.
