“In the case of Iztapalapa, water scarcity has always been a big problem,” said Mariano Salazar, a 69-year-old community leader in the district. “There are almost 2 million of us in this municipality and we require 100 million cubic meters of water a year.”
Frustrations over the situation have fueled unrest. In January, protesters in the municipality of Acambay forced open the gate of an office of Mexico’s National Water Commission and broke windows, as reported by Reuters.
Local authorities have urged residents to conserve water and prioritize what is available for drinking, particularly as temperatures this week hover around 85 F.
More than 24 million people in southern Africa face hunger, malnutrition and water scarcity due to drought and floods, an aid group has warned, as experts say the situation risks spiraling into an “unimaginable humanitarian situation.”
The warning from Oxfam on Wednesday came as Zimbabwe joined other southern African nations in declaring its drought a national disaster, following earlier declarations by Zambia and Malawi.
Zimbabwean President Emmerson Mnangagwa said more than 2.7 million people in the country will go hungry this year and more than $2 billion in aid is required for the country’s national response, Reuters reported.
An accelerator known as a muon collider could revolutionize particle physics—if it can be built.
(TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull. This is a penetrating injury.
Symptoms of a TBI can be mild, moderate, or severe. Concussions are a type of mild TBI. The effects of a concussion can sometimes be serious, but most people completely recover in time. More severe TBI can lead to serious physical and psychological symptoms, coma, and even death.
“We need to accelerate and intensify efforts to recover Antarctic meteorites,” said Dr. Harry Zekollari. “The loss of Antarctic meteorites is much like the loss of data that scientists glean from ice cores collected from vanishing glaciers – once they disappear, so do some of the secrets of the universe.”
How can climate change effect the search for meteorites in Antarctica? This is what a recent study published in Nature Climate Change hopes to address as an international team of researchers investigated how melting snow and ice could prevent successful identification of meteorites, of which approximately 60 percent of all meteorites retrieved on Earth have been found in Antarctica. This study holds the potential to help scientists, climate change activists, and legislators better understand the impacts of climate change on science, as meteorites are crucial for gaining greater insight into the formation and evolution of the solar system and beyond.
With a combination of climate models, satellite observations, and artificial intelligence, the researchers estimate that at current rates, they will lose the ability to identify approximately 5,000 meteorites annually, with approximately 24 percent being lost by 2050 and potentially 76 percent by 2100.

An international research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) 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.
The SpaceX Raptor engines are becoming far more powerful and should reach over 330 tons of force while not needing a heat shield. Removing the need for a heat shield will lower the overall mass and increase the thrust to weight ratio.
The programmable so-called “metafluid” is made of rubber-like spheres that allow it to radically alter its properties.
