Controlling root growth direction could help save crops and mitigate climate change      (via sciencedaily.com)     Original source 

Scientists have determined how the well-known plant hormone ethylene is crucial in controlling the angle at which roots grow. The findings can be used to engineer plants and crops that withstand the environmental stresses of climate change and drought, and perhaps to create plants that remove carbon dioxide from the atmosphere and store it deep underground to help mitigate climate change.

Nanoparticles that can light up the lymph node cancer cells otherwise undetectable by MRI      (via sciencedaily.com)     Original source 

Researchers have developed a new nanoparticle that can 'hitch a ride' on immune cells, or monocytes. Because of its tiny size, the particle can tag along directly into lymph nodes and help metastasis show up on MRIs where it would otherwise be too hard to detect. The process offers game-changing benefits for the early detection of cancer metastasis in the lymph nodes. While previously, metastasis could only be assessed by an increase in lymph node size; the new particles could lead to MRI contrast agents that can highlight metastatic cells in lymph nodes that may otherwise appear normal.

Greetings from the island of enhanced stability: The quest for the limit of the periodic table      (via sciencedaily.com)     Original source 

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high atomic numbers up to 118 and are significantly heavier than uranium, the element with the highest atomic number (92) found in larger quantities on Earth. This raises questions such as how many more of these superheavy species are waiting to be discovered, where -- if at all -- is a fundamental limit in the creation of these elements, and what are the characteristics of the so-called island of enhanced stability. In a recent review, experts in theoretical and experimental chemistry and physics of the heaviest elements and their nuclei summarize the major challenges and offer a fresh view on new superheavy elements and the limit of the periodic table.

Scientists study the behaviors of chiral skyrmions in chiral flower-like obstacles      (via sciencedaily.com)     Original source 

Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges. Scientists have recently studied the random walk-behaviors of chiral skyrmions by simulating their dynamics within a ferromagnetic layer surrounded by chiral flower-like obstacles. The simulations reveal that the system behaves like a topological sorting device, indicating its use in information processing and computing devices.

New trial highlights incremental progress towards a cure for HIV-1      (via sciencedaily.com)     Original source 

A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.

Sandalwood oil by-product prevents prostate cancer development in mice      (via sciencedaily.com)     Original source 

Sandalwood oil has been used worldwide for centuries. Now, a study is the first to demonstrate in vivo the chemo-preventive properties of a by-product of the oil in a mouse model. Results show administering alpha-santalol reduced visible prostate tumors, protected the normal tissue, and delayed progression from a precancerous condition to a high-grade form of cancer. These findings are significant because mortality in prostate cancer patients is mainly attributable to advanced stages of the disease.

Nutrients direct intestinal stem cell function and affect aging      (via sciencedaily.com)     Original source 

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the aging gut.

The Complete Library of Charles Darwin revealed      (via sciencedaily.com)     Original source 

Charles Darwin -- arguably the most influential man of science in history, accumulated a vast personal library throughout his working life. Until now, 85 per cent of its contents were unknown or unpublished. This year, coinciding with Darwin's 215th birthday, The Complete Work of Charles Darwin Online, a scholarly project, has released an online 300-page catalogue detailing Darwin's complete personal library, with 7,400 titles across 13,000 volumes and items including books, pamphlets and journals.

Surprisingly vibrant color of 12-million-year-old snail shells      (via sciencedaily.com)     Original source 

Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed. Residues of ancient color patterns are therefore very rare. This makes a new discovery all the more astonishing: researchers found pigments in twelve-million-year-old fossilized snail shells.

How electron spectroscopy measures exciton 'holes'      (via sciencedaily.com)     Original source 

Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the bond between electrons and holes, they were able to gain a microscopic insight into charge transfer processes across a semiconductor interface.
