Long-period oscillations control the Sun's differential rotation
- ScienceDaily
- 24/3/27 23:25
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...

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.
Could AI play a role in locating damage to the brain after stroke?
- ScienceDaily
- 24/3/27 23:25
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).

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.
A combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis
- ScienceDaily
- 24/3/27 20:50
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.
Astronomers conduct first search for forming planets with new space telescope
- ScienceDaily
- 24/3/27 20:49
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior
- ScienceDaily
- 24/3/27 20:49
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.
Combining epigenetic cancer medications may have benefit for colorectal cancers and other tumor types
- ScienceDaily
- 24/3/27 20:49
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...
Land under water: What causes extreme flooding?
- ScienceDaily
- 24/3/27 20:48
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...
Robot, can you say 'cheese'?
- ScienceDaily
- 24/3/27 20:48
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?
Researchers turn back the clock on cancer cells to offer new treatment paradigm
- ScienceDaily
- 24/3/27 17:48
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.
Making long-term memories requires nerve-cell damage
- ScienceDaily
- 24/3/27 17:48
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.
Sweet success: Sugarcane's complex genetic code cracked
- ScienceDaily
- 24/3/27 17:48
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.

Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Rock-wallaby bite size ‘packs a punch’
- ScienceDaily
- 24/3/27 17:47
Australian rock-wallabies are 'little Napoleons' when it comes to compensating for small size, packing much more punch into their bite than larger relatives. Researchers made the discovery while investigating how two dwarf species of rock-wallaby are able to feed themselves on the same kinds of foods as their much larger cousins.
Scientists extract genetic secrets from 4,000-year-old teeth to illuminate the impact of changing human diets over the centuries
- ScienceDaily
- 24/3/27 17:47
Researchers have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze Age to today. The teeth both belonged to the same male individual and also provided a snapshot of his oral health.
