The President's Council of Advisors on Science and Technology (PCAST) brings together the Nation's foremost luminaries in science and technology to advise the President and provide recommendations on strengthening American leadership in science and technology.
Researchers used data from two health studies to track the caffeine-drinking habits of more than 130,000 people over four decades. They found that drinking 2-3 cups of coffee or 1-2 cups of tea a day was associated with the greatest reductions in rate of cognitive decline, a result that held true even in people with a genetic variant called APOE4, which is associated with Alzheimer's disease.
His message is clear: our world is built on abundant energy, around 80% of which has come from fossil fuels over the past 50 years. Because supplies are limited, energy consumption will peak in decades - sooner if humans attempt to limit climate change. To keep global warming below 1.5 °C by 2100, the use of fossil fuels must fall by 5-8% each year - a pace that is too fast for low-carbon energy to keep up with.
Pottery made by people of the Halafian culture, who inhabited northern Mesopotamia between around 6200 and 5500 BC, is painted with flowers that have 4, 8, 16 or 32 petals, and some show arrangements of 64 flowers. These patterns show a clear understanding of symmetry and spatial division long before written numbers came into use around 3400 BC, argue scientists in a new study. The skill might have helped the Halafian people with tasks such as sharing harvests or dividing communal fields, the authors say.
A researchers' propensity for risky projects is passed down to their doctoral students - and stays with trainees after they leave the laboratory, according to an analysis of thousands of current and former PhD students and their mentors.
From The Weather Channel: More than 300,000 homes and businesses remained without power Thursday morning after damaging winds slammed multiple states, including South Dakota, Colorado, Oregon, Idaho, Montana and Washington state. Nearly two dozen winds gusts of more than 100 mph were recorded Wednesday. The powerful winds brought down trees and powerlines killing one man and critically injuring two children.
There is hope. Japan's ruling Liberal Democratic Party (LDP) and its coalition partner, the Japan Innovation Party (JIP), have released an agreement that pledges to "substantially expand" grants for scientific research and to "establish a system granting legal effect to the use of maiden names". Both are promising for researchers, but the future of Japanese science will depend on how these policies are implemented.
Around the world, budgets for fundamental research - studies that seek primarily to advance knowledge for its own sake, without an expectation of a return on investment - are coming under pressure to an extent not seen for at least a generation. In the United States, the principal funder of fundamental research, the National Science Foundation, has this year terminated some 1,600 grants worth a total of US$1 billion, a huge chunk of its $10 billion budget.
Good morning. I've spent the week talking to business leaders and policymakers who've gathered in New York for Climate Week, the UN General Assembly and assorted events on the sidelines, including our own. The mood is generally somber, with growing concern about America's commitment to free speech, science, rule of law and remaining a hub for global talent. A few themes have emerged in terms of how CEOs are shifting their strategies.
Major energy producers increased the likelihood and intensity of heatwaves, according to research published in Nature. Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would have been "virtually impossible" without climate change, and that nearly a quarter of the heatwaves recorded from 2000 to 2023 can be directly linked to the greenhouse-gas emissions from individual energy giants.
The federal government is filled with scientists who contribute to decisions regarding food, medicines, environment, health care, and more. However, as President Trump's second term began, many scientists noticed a shift towards an antiscience approach.
The executive order promises to ensure that "federal decisions are informed by the most credible, reliable, and impartial scientific evidence available." In practice, however, it gives political appointees authority to define scientific integrity and decide which evidence counts and how it should be interpreted.
