The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations discovered in 2021 play a crucial role in controlling the Sun's rotational pattern. The long-period oscillations are analogous to the baroclinically unstable waves in Earth's atmosphere that shape the weather. In the Sun, these oscillations carry heat from the slightly hotter poles to the slightly cooler equator.
Researchers have introduced a new, refined method for analyzing brain signals, enhancing our understanding of brain functionality. This research has the potential to improve treatments for neurological conditions such as Parkinson's disease, pain, epilepsy and depression.
Artificial intelligence (AI) may serve as a future tool for neurologists to help locate where in the brain a stroke occurred. In a new study, AI processed text from health histories and neurologic examinations to locate lesions in the brain. The study looked specifically at the large language model called generative pre-trained transformer 4 (GPT-4).
Researchers can use the light naturally thrown off by biological specimens to better study the different states of stem cells in the nervous system, thanks to a tool brightening their chances for studying the way stem cells age.
Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.
New research finds that not all cattle are the same when it comes to grazing, and knowing that could lead to better animal health and range conditions.
Researchers have found that approved drugs that were originally shown to normalize blood vessels surrounding tumors (to improve drug delivery to cancer cells) can enhance the delivery of anti-microbial medications to kill tuberculosis bacteria residing in the lungs.
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Legislators love bundling things together. It lets them accomplish more with less hassle and attempt to make legislation more appealing to a broader group. But a new study suggests that this can sometimes backfire. The authors found that pairing climate policies with other policies does not necessarily increase their popular appeal, and can actually reduce public support.
Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
Experiencing puberty earlier, compared to same-age peers, may be one of the mechanisms through which childhood risk factors influence adult cardiometabolic health issues, according to a new study.
Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.
A pair of medications that make malignant cells act as if they have a virus could hold new promise for treating colorectal cancers and other solid tumors, reports a new study. The preclinical research determined how low doses of a DNMT inhibitor sensitize cancer cells to an EZH2 inhibitor, resulting in a one-two punch that combats cancer cells better than either drug alone. The findings are the foundation for an upcoming Phase I clinical trial to evaluate this combination in people with colorectal cancer or other solid tumors.
A global shift to a healthier, more sustainable diet could be a huge lever to limit global warming to 1.5 C, researchers find. The resulting reduction of greenhouse gas emissions would increase the available carbon budget compatible with limiting global warming to 1.5 C, and allow to achieve the same climate outcome with less carbon dioxide removal and less stringent CO2 emissions reductions in the energy system. This would also reduce emission prices, energy prices and food expenditures.
If rivers overflow their banks, the consequences can be devastating -- just like the catastrophic floods in North Rhine-Westphalia and Rhineland-Palatinate of 2021 showed. In order to limit flood damage and optimize flood risk assessment, we need to better understand what factors can lead to extreme forms of flooding and to what extent. Using methods of explainable machine learning, researchers have shown that floods are more extreme when several factors are involved in their development.
What would you do if you walked up to a robot with a human-like head and it smiled at you first? You'd likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back?
Scientists reversed an aggressive cancer, reverting malignant cells towards a more normal state. Rhabdoid tumors are an aggressive cancer which is missing a key tumor suppressor protein. Scientists discovered that removing a second protein from cancer cells already experiencing tumor suppressor loss can reverse cancer cell identity.
Just as you can't make an omelet without breaking eggs, scientists have found that you can't make long-term memories without DNA damage and brain inflammation.
New multidisciplinary research could lead to more efficient televisions, computer screens and lighting.
Scientists created a highly accurate reference genome for one of the most important modern crops and found a rare example of how genes confer disease resistance in plants. Exploring sugarcane's genetic code could help researchers develop more resilient and productive crops, with implications for both sugar production and biofuels.
