New tool provides researchers with improved understanding of stem cell aging in the brain

Science Daily - 28/03/2024
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.

Artificial reef designed by MIT engineers could protect marine life, reduce storm damage

Science Daily - 28/03/2024
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.

Understanding cattle grazing personalities may foster sustainable rangelands

Science Daily - 28/03/2024
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

Science Daily - 28/03/2024
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

Science Daily - 28/03/2024
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

Science Daily - 28/03/2024
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

Science Daily - 28/03/2024
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.

Land under water: What causes extreme flooding?

Science Daily - 28/03/2024
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.

Robot, can you say 'cheese'?

Science Daily - 28/03/2024
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

Science Daily - 27/03/2024
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

Science Daily - 27/03/2024
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.

More efficient TVs, screens and lighting

Science Daily - 27/03/2024
New multidisciplinary research could lead to more efficient televisions, computer screens and lighting.

Sweet success: Sugarcane's complex genetic code cracked

Science Daily - 27/03/2024
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.

Getting too little sleep linked to high blood pressure

Science Daily - 27/03/2024
Sleeping fewer than seven hours is associated with a higher risk of developing high blood pressure over time, according to a new study.

A solar cell you can bend and soak in water

Science Daily - 27/03/2024
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’

Science Daily - 27/03/2024
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

Science Daily - 27/03/2024
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.

Spot-on laser treatment for skin blemishes becoming clearer with new index

Science Daily - 27/03/2024
Scientists have developed the first wavelength-specific irradiation index for picosecond lasers, which are used in clinical practice to treat pigmented lesions. Comparison with previously reported clinical studies confirmed that clinical results showing low complication rates and high efficacy can be explained by the indicator they developed. The use of this indicator is expected to help set irradiation conditions in clinical practice.

Scientists warn: The grey seal hunt is too large

Science Daily - 27/03/2024
Researchers warn that today's hunting quotas of about 3,000 animals pose a risk to the long-term survival of the grey seal in the Baltic Sea. The conclusions of this new study are based on statistics from 20th century seal hunting and predictions of future climate change.

Want to feel young? Protect your sleep

Science Daily - 27/03/2024
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.
