Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Worldwide over the past 35 years, dams and land reclamation activities converted 250,000 acres of estuary -- an area roughly 17 times the size of Manhattan -- to urban land or agricultural fields, with most land conversion and estuary loss in rapidly developing countries, a new study finds. The findings could help developing countries avoid problems faced by countries that have already lost or degraded their estuaries.
A new expert consensus statement aims to improve endometriosis evaluation. Endometriosis is a common condition with substantial diagnostic delay, leading patients to experience pain, infertility, lost wages and interrupted relationships. The consensus provides recommendations for augmenting routine pelvic ultrasounds through additional maneuvers and imaging to improve diagnosis of deep endometriosis.
Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.
The findings may also have implications for learning and memory disorders, including Fragile X syndrome.
Understanding how social media is used during a disaster can help with disaster preparedness and recovery for future events.
Investigators have assembled the most comprehensive atlas to date of messenger RNA (mRNA) variants in the mouse and human brain. The atlas is an important new resource in understanding brain development, neuron specialization and other brain functions.
With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.
Researchers have compiled a detailed catalogue of bacteria living in cancer metastases. Having analyzed over 4000 tumors, they shed light on the diversity of these co-inhabitants and how they might interact with cancer cells and their surroundings. For example, certain bacteria were linked to a worse response to immunotherapy. This study paves the way to a better understanding of how bacteria help or hinder cancer (therapy), and how we can use this for patients' advantage.
A team has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state -- an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.
Esophageal squamous cell carcinoma (ESCC) accounts for around 90% of esophageal cancers, especially in East Asia. New findings in indicate that periostin, or POSTN, promotes ESCC progression by enhancing cancer and stromal cell migration in cancer-associated fibroblasts (CAFs). Therefore, it may be a novel therapeutic target for treating ESCC.
Researchers use network analysis to study whether it can reveal the subtle changes associated with subjective cognitive decline that cannot otherwise be detected through standard test analyses. By running a statistical analysis of data merged from two large Canadian data sets, the researchers were able to visualize the strength of relationships between the nodes among people who are classified as cognitively normal (CN), or who have diagnoses of subjective cognitive decline (SCD), mild cognitive impairment (MCI) or Alzheimer's disease (AD).
Researchers have identified new variations in neuroblastoma that could lead to a more accurate prognosis and better-targeted treatments for this devastating childhood cancer. A study reveals three new subgroups of the most common type of neuroblastoma, each with different genetic traits, expected outcomes, and distinguishing features that offer clues as to which treatments may be most effective.
An improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces aging effects, an international team demonstrated.
Researchers have discovered a simple, but effective, strategy to help people reduce their feelings of anger. Disposing of a piece of paper containing your written thoughts on the cause of your anger can effectively neutralize it. This process is like a Japanese tradition called hakidashisara, in which people write their negative thoughts on a plate then destroy it. Their findings suggest a simple and effective method of suppressing anger supported by science.
Common 'hard' coastal defenses, like concrete sea walls, might struggle to keep up with increasing climate risks. A new study shows that combining them with nature-based solutions could, in some contexts, create defenses which are better able to adapt.
Byzantine bullion fueled Europe's revolutionary adoption of silver coins in the mid-7th century, only to be overtaken by silver from a mine in Charlemagne's Francia a century later, new tests reveal. The findings could transform our understanding of Europe's economic and political development.
Researchers offer insights into the ethical dilemmas and legal complexities surrounding brain organoids, especially those derived from human fetal tissue. Their findings advocate for thorough regulatory frameworks to ensure that scientific and medical progress in this field is conducted responsibly and ethically, with strong regulations supported by sound ethical and legal principles.
The globe has now experienced 12 months with average monthly temperatures 1.58 degrees Celsius (2.8 degrees Fahrenheit) above the Paris threshold, according to Copernicus data.
The 42.7-metre Angara launch vehicle, capable of carrying payloads bigger than 20 tonnes into orbit, is being developed to replace Russia's Proton M as Russia's heavy-lift rocket
