To discover and confirm the presence of a planet around stars other than the Sun, astronomers wait until it has completed three orbits. However, this very effective technique has its drawbacks since it cannot confirm the presence of planets at relatively long periods (it is ideally suited for periods of a few days to a few months).
NEW YORK...July 18, 2018 - A new highly maneuverable search and rescue robot that can creep, crawl and climb over rough terrain and through tight spaces has been developed by Ben-Gurion University of the Negev (BGU) researchers.
In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel - just as plants do - researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have pioneered a technique that uses nanoscale imaging to understand how local, nanoscale properties can affect a material's macroscopic performance.
Belmont, MA - McLean Hospital researchers have completed a study that sought to determine which individuals with depression are best suited for antidepressant medications.
Sawtooth swings -- up-and-down ripples found in everything from stock prices on Wall Street to ocean waves -- occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some plasmas are free of sawtooth gyrations thanks to a mechanism that has long puzzled physicists.
Having an early supper or leaving an interval of at least two hours before going to bed are both associated with a lower risk of breast and prostate cancer. Specifically, people who take their evening meal before 9 pm or wait at least two hours before going to sleep have an approximate 20% lower risk of those types of cancer compared to people who have supper after 10pm or those who eat and go to bed very close afterwards, respectively.
Goofy, yellow and crooked: British smiles have sometimes had a less-than-flattering international image, but a new study has put tartar from our infamously bad teeth to good use.
Researchers analysing the teeth of Britons from the Iron Age to the modern day have unlocked the potential for using proteins in tooth tartar to reveal what our ancestors ate.
Dental plaque accumulates on the surface of teeth during life and is mineralised by components of saliva to form tartar or "dental calculus", entombing proteins from the food we eat in the process.
As Tropical Depression 11W was strengthening into Tropical Storm Son-tinh near the northern Philippines, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall.
TD11W or Son-Tinh, is the first tropical cyclone of 2018 for the northern Philippines, where the storm is known locally as "Tropical Cyclone Henry."
TALLAHASSEE, Fla. -- Women CEOs in America are paid less, have shorter tenures and their companies are punished in the stock market, even when their firms are just as profitable as those run by men, according to new research from Florida State University.
In addition, women CEOs are less likely to serve as board chair of their companies, and they have a much tougher time landing the top job because there is significantly less demand for their leadership compared to men.
FINDINGS
In a small study of military personnel who had suffered head trauma and had reported memory and mood problems, UCLA researchers found brain changes similar to those seen in retired football players with suspected chronic traumatic encephalopathy, a degenerative brain disease linked to repeated blows to the head.
