AUSTIN, Texas -- A rule to limit trading based on nonpublic stock information has limited effectiveness, according to a recent study by Texas McCombs Finance Professor Robert Parrino. Issued in 2000 by the Securities & Exchange Commission, Rule 10b5–1 requires corporate insiders to schedule the purchase or sale of a predetermined number of shares through a third-party broker up to two years in advance. Because the trades under these “plan” sales are scheduled in advance of their execution, insiders are presumed less likely to be acting on inside information. But ...

A special brain-wave cap can diagnose stroke in the ambulance, allowing the patient to receive appropriate treatment faster. Jonathan Coutinho, neurologist at Amsterdam UMC, is one of the inventors the swimming cap: "Our research shows that the brain-wave cap can recognize patients with large ischemic stroke with great accuracy. This is very good news, because the cap can ultimately save lives by routing these patients directly to the right hospital." The research is published today in Neurology.  Every year, millions of people worldwide suffer an ischemic stroke, the most common type of stroke. An ischemic stroke occurs ...

Aspergillus fumigatus is the major airborne fungus present indoors and outdoors that causes various diseases, the severity of which are dependent on an individual’s immune status.  Researchers in the College of Pharmacy at the University of Tennessee Health Science Center have received a $423,500 grant from the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health for research aimed at reducing disease and mortality rates associated with Aspergillus infections ...

Lugano, Switzerland, 17 October 2023 – Women living and working in places with higher levels of fine particle air pollution are more likely to get breast cancer than those living and working in less polluted areas. Results of the first study to take account of the effects of both residential and workplace exposure to air pollution on breast cancer risk are presented at the ESMO Congress 2023 in Madrid, Spain (1).   “Our data showed a statistically significant association between long term exposure to fine particle air pollution, at home and at work, and risk of breast cancer. This contrasts with previous research which looked only at fine particle exposure ...

Different strains of E.coli can outcompete one another to take over the gut, a new study reveals. Publishing their findings today in PLOS Biology, scientists reveal that a particular strain, known as MDR ST131, can readily colonise new hosts, even if those hosts are already have E.coli in their healthy gut. The international team, led by experts at the University of Birmingham, used a mouse model to help understand why strains of E.coli that live in a healthy gut are rapidly overtaken of when challenged with a multi-drug resistant strain. Lead author Professor Alan McNally, from ...

Sleeping patterns and stress hormones could be the key to understanding how and when people with epilepsy are likely to experience seizures, a new study reveals.  Researchers used mathematical modelling to understand the impact of different physiological processes, such as sleep and changes in concentration of the stress-hormone cortisol, on key signatures of epilepsy – known as epileptiform discharges (ED). Epilepsy is a serious neurological disorder characterised by a tendency to have recurrent, spontaneous seizures. Classically, seizures were assumed to occur at random, until the discovery of ED activity with timescales that vary from hours and days through to months. The scientists ...

CAMBRIDGE, Mass. -- Anyone who has ever tried to pack a family-sized amount of luggage into a sedan-sized trunk knows this is a hard problem. Robots struggle with dense packing tasks, too.  For the robot, solving the packing problem involves satisfying many constraints, such as stacking luggage so suitcases don’t topple out of the trunk, heavy objects aren’t placed on top of lighter ones, and collisions between the robotic arm and the car’s bumper are avoided.  Some traditional methods tackle this problem sequentially, guessing a partial solution ...

Glioblastoma is the most common type of brain tumor that affects adults and, unfortunately, still remains incurable. In a new study, researchers have demonstrated that a specific mitochondrial protein plays an important role in glioblastoma, and can therefore be used as a potential target to reduce tumors. “Glioblastoma is notorious for its lethality. One of the major challenges is that it spreads invasively throughout the brain. We’re interested in understanding what drives this process in order to identify new therapeutic strategies,” said Brendan Harley (RBTE leader/EIRH), the Robert W. Schaefer Professor of Chemical ...

Key takeaways Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding  population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population. A new genomic study by UCLA biologists shows that whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding, or “effective,” population — 29% more than previously thought. But there is also some good news: Genes among members of this endangered ...

By Benjamin Boettner (Boston) — The lung is one of the tissues most sensitive to radiation in the human body. People exposed to high radiation doses following nuclear incidents develop radiation-induced lung injury (RILI), which affects the function of many cell types in the lung, causing acute and sustained inflammation, and in the longer term, the thickening and scarring of lung tissue known as fibrosis. RILI also is a common side effect of radiation therapy administered to cancer patients to kill malignant cells in their bodies, and can limit the maximum radiation dose doctors can use to control their ...

Texas A&M University scientists and research partners have received two National Institute of Food and Agriculture (NIFA) Agriculture and Food Research Initiative (AFRI) grants to study the spread of SARS-CoV-2 in deer. These funds will help researchers understand the impact of the virus in Texas’ deer populations and its relationship to human and ecological health. For these projects, the research team will focus on captive deer, which are an agricultural species in Texas, including managed deer that live on large, rural properties enclosed by fences, as well as on the wild deer with which captive deer may interact and deer living ...

WASHINGTON, Oct. 17, 2023 – Wave energy technology is a proven source of power generation, but there is power inherent in every molecule of liquid on earth, even when the liquid is at rest. At the molecular scale, atoms and ions are always moving. If this nanoscale movement can be harvested, it could be a big source of energy. “There are vast amounts of air and liquid on the earth, and their successful harvesting could produce a gigantic amount of energy for society,” author Yucheng Luan said. In an article published this week in APL Materials, by AIP Publishing, Luan and his collaborators tested a molecular energy harvesting device that captures ...

For many people seaweed holds a reputation as a superfood, heralded for its health benefits and sustainability, but it appears our European ancestors were ahead of the game and were consuming the nutrient-rich plant for thousands of years. Researchers say they have found “definitive” archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only ...
