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.

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.

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.

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.

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.

Young adults who were prescribed stimulant medications for attention-deficit/hyperactivity disorder (ADHD) were significantly more likely to develop cardiomyopathy (weakened heart muscle) compared with those who were not prescribed stimulants, in a new study.

Sleeping fewer than seven hours is associated with a higher risk of developing high blood pressure over time, according to a new study.

Umwelt is a new a system that enables blind and low-vision users to author accessible, interactive charts representing data in three modalities: visualization, textual description, and sonification.

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.

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.

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.

Do you ever find yourself longing for the energy and vitality of your younger years? Feeling young is not just a matter of perception it is actually related to objective health outcomes. Previous studies have shown that feeling younger than one s actual age is associated with longer, healthier lives. There is even support for subjective age to predict actual brain age, with those feeling younger having younger brains. Feeling sleepy can make you feel ten years older.

Focusing a tailored laser beam through transparent glass can create a tiny spot inside the material. Researchers have reported on a way to use this small spot to improve laser material processing, boosting processing resolution.

Neighborhoods with more adversity have up to twice the increased risk of heart disease and stroke, according to a new study.

Reserachers found that people who were more active in their free time had a lower chance of having various types of chronic pain 7-8 years later. For example, being just a little more active, such as going from light to moderate activity, was associated with a 5% lower risk of reporting some form of chronic pain later. For severe chronic pain in several places in the body, higher activity was associated with a 16% reduced risk. The researchers found that the ability to tolerate pain played a role in this apparent protective effect. Читать дальше...

Researchers have used data from UK Biobank participants to reveal that diabetes, traffic-related air pollution and alcohol intake are the most harmful out of 15 modifiable risk factors for dementia.

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also... Читать дальше...

Anthropologists created a computational model to predict the likelihood of animal extinctions based on the complex interaction of hunting and environmental change.

A common GP assessment used to monitor depression treatment does not provide any immediate benefits to patients. Experts testing the PHQ-9 assessment that measures the severity of depression found it did nothing to improve symptoms in first three months.
