Researchers have found a way to reduce guesswork and errors in genetic engineering by eliminating unwanted or 'junk' genes from plant chromosomes. This new method allows for targeted gene insertion and excision, enabling more precise control over genetic transformations.
A recent earthquake in Peru has bolstered a researcher's theory that large earthquakes will not occur in a specific region near the quake site. The study found a correlation between plate shape and seismic activity, identifying areas of low seismicity called seismic gaps.
In a new study, biologist David Anderson found that masked boobies kill their own young to maximize reproductive success. By laying two eggs, the birds decrease their risk of total reproductive failure to about 16 percent.
Scientists have discovered that randomness in lubricants is a major contributor to friction at the molecular level. This finding could lead to reduced wear and tear on machinery. By understanding how lubricants fracture and heal, researchers may develop new methods to control friction and minimize wear.
A study found that average people struggle to understand environmental impact statements, with only 42% recalling basic facts. However, editing and incorporating 'before and after' visuals significantly improved comprehension, increasing understanding levels to over 80%. This highlights the need for clear and accessible EIS documents.
Scientists have found that dysregulation of programmed cell death may underlie the earlier onset and rapid downhill course of inherited forms of Alzheimer's disease. The study suggests that a specific gene, PS2, plays a crucial role in apoptosis and may contribute to neurodegeneration by triggering a stress response.
A recent study found that high levels of nitrogen deposition in grasslands lead to the loss of plant species diversity and the disruption of ecosystem functioning. Native prairie species are particularly vulnerable to the negative effects of excessive nitrogen addition, which can cause their extinction and reduce carbon storage.
A new company in Florida plans to introduce its revolutionary wheelchair, powered by Oak Ridge National Laboratory's (ORN L) innovative technology. The TransRovr features omnidirectional movement and a three-piece modular construction, allowing for enhanced ergonomics and convenience.
A recent study published in The Lancet found that a specific HIV vaccine, MNrgp120, did not stop the virus from reproducing or slow immune system destruction. Researchers evaluated 568 volunteers infected with HIV and found no significant differences in CD4 counts between those who received the vaccine and those who received a placebo.
A multinational team of researchers, led by Syracuse University's K. Douglas Nelson, has discovered a partially molten crust beneath the Himalaya and Tibetan Plateau using seismic reflection and other techniques. This finding challenges traditional views of plate tectonics and may explain the flatness of the Tibetan Plateau.
A team of experts from UC Berkeley's engineering school have developed a machine to zap static cling, allowing fragile ancient papyrus documents to survive. The recovery includes royal proclamations, land transactions, and literary texts from the third century B.C., dating back thousands of years.
Six American institutions are putting ancient manuscript collections online through the Advanced Papyrological Information System (APIS), making fragile materials accessible to scholars worldwide. The effort aims to digitize and link images, texts, and bibliography for easier research.
Men want to be involved in family planning but are often ignored, with a significant disparity between research on women and men. Studies found that men's reproductive goals are similar to those of women, highlighting the need for inclusive family planning programs.
Researchers at the University of Washington have discovered that removing a brain chemical called neuropeptide Y (NPY) can help reduce body fat in genetically obese mice. The study found that mice lacking NPY become only half as fat, eat less, and have a higher metabolic rate compared to their morbidly obese cousins.
Researchers at the University of Illinois have developed a fast measurement technique that sheds light on the early stages of protein folding. The initial steps of helix formation occur within several hundred nanoseconds, and the entire collapse to a compact structure appears nearly complete after just a few microseconds.
Researchers are inserting prosthetic heart valves into pigs to study their interaction with blood and hearts, aiming to reduce or eliminate the need for anticoagulants. The goal is to develop more durable valves that can last longer than current mechanical and tissue valves.
Researchers at the University of Kansas have improved near-field optical scanning microscopy to study individual biological molecules. The new cantilevered probe reduces force on samples, allowing for gentler interaction and high sensitivity.
A study by researchers at the University of Illinois found that premature infants have a lower chance of developing a secure attachment with their mothers. The study observed infant-mother interactions and found that 75% of full-term babies were rated as secure, but only 50% of premature babies shared this level of security.
A new theory on plasma turbulence warns that ITER's energy confinement could be shortened, making it difficult to ignite a fusion burn. The theory's calculations suggest ITER might only produce a few times the energy used to heat the plasma, rendering it unreliable for generating abundant power.
A University of Illinois professor and his students have developed a power-tracking circuit that maximizes electrical power-conversion process efficiency. The circuit automatically adjusts to provide maximum energy out of solar cells for various applications, including large home appliances.
