Discovery of critical iron-transport protein in malaria parasites could lead to faster-acting medications
2024-10-28
Malaria kills over 600,000 people a year, and as the climate warms, the potential range of the disease is growing. While some drugs can effectively prevent and treat malaria, resistance to those drugs is also on the rise.
New research from University of Utah Health has identified a promising target for new antimalarial drugs: a protein called DMT1, which allows single-celled malaria parasites to use iron, which is critical for parasites to survive and reproduce.
The results suggest that medications that block DMT1 might be very effective against malaria.
The new results are published in PNAS.

Risky choices: How US laws affect migrant children’s journeys to border
2024-10-28
U.S. immigration law and the legal categorizations it imposes on migrants shape the journeys of migrant children from Central America as they move through Mexico toward the southern U.S. border, according to a new Yale study.
In the study, sociologist Ángel Escamilla García documents the various hard decisions Central American youth are forced to make during their journeys to maximize their chances of not being deported once they reach the United States. Those choices include concealing sexual assaults, beatings, and other crimes ...

Don’t skip colonoscopy for new blood-based colon cancer screening, study concludes
2024-10-28
Newly available blood tests to screen for colorectal cancer sound far more appealing than a standard colonoscopy. Instead of clearing your bowels and undergoing an invasive procedure, the tests require only a simple blood draw. But are the tests effective?
A study led by researchers at Stanford Medicine concluded that the new tests are ideal for people who shy away from other colorectal cancer screening. However, if too many people who would have undergone colonoscopies or stool-based tests switch to the blood tests, colorectal cancer death rates will rise. Because the more established colonoscopies and stool tests ...

Chemicals produced by fires show potential to raise cancer risk
2024-10-28
Derek Urwin has a special stake in his work as a cancer control researcher. After undergraduate studies in applied mathematics at UCLA, he became a firefighter. His inspiration to launch a second career as a scientist was the loss of his brother, Isaac, who died of leukemia at only 33 despite no history of cancer in their family. Working with Anastassia Alexandrova, a professor of chemistry and biochemistry in the UCLA College, he earned his doctorate.
Urwin is now a UCLA adjunct professor of chemistry — and still a full-time firefighter with the Los Angeles County Fire Department. In a recent publication, his science shed new light on the chemical underpinnings of exposures ...

Bird wings inspire new approach to flight safety
2024-10-28
Taking inspiration from bird feathers, Princeton engineers have found that adding rows of flaps to a remote-controlled aircraft’s wings improves flight performance and helps prevent stalling, a condition that can jeopardize a plane’s ability to stay aloft.
“These flaps can both help the plane avoid stall and make it easier to regain control when stall does occur,” said Aimy Wissa, assistant professor of mechanical and aerospace engineering and principal investigator of the study, published in the Proceedings ...
Global fleet of undersea robots reveal the phytoplankton hidden beneath the ocean's surface
2024-10-28
Marine phytoplankton are fundamental to Earth’s ecology and biogeochemistry. Our understanding of the large-scale dynamics of phytoplankton biomass has greatly benefited from, and is largely based on, satellite ocean color observations from which chlorophyll-a (Chla), a commonly used proxy for carbon biomass, can be estimated. However, ocean color satellites only measure a small portion of the surface ocean, meaning that subsurface phytoplankton biomass is not directly monitored. Chla is also an imperfect ...
Climate, dead zones and fish: Solving a 'wicked problem' in Lake Erie and beyond
2024-10-28

There's a famous piece of advice from hockey, attributed to Wayne Gretzky, about how it's better to skate to where the puck is headed rather than where it is.
Research is now showing that regulations designed to protect Lake Erie's water quality are heeding the Great One's words when it comes to safeguarding the Great Lake's fisheries.
Specifically, the currently recommended limits on the flow of nutrients into Lake Erie from agriculture may be too restrictive for some species of fish. They are, however, suited to maintain healthy fisheries until the ...
Dinosaurs thrived after ice, not fire, says a new study of ancient volcanism
2024-10-28
201.6 million years ago, one of the Earth's five great mass extinctions took place, when three-quarters of all living species suddenly disappeared. The wipeout coincided with massive volcanic eruptions that split apart Pangaea, a giant continent then comprising almost all the planet's land. Millions of cubic miles of lava erupted over some 600,000 years, separating what are now the Americas, Europe and North Africa. It marked the end of the Triassic period and the beginning of the Jurassic, the period when dinosaurs arose to take the place of Triassic creatures and dominate the planet.
The exact mechanisms of the End Triassic Extinction have long been debated, ...
Green growth: 30% of regions worldwide achieve economic growth while reducing carbon emissions
2024-10-28
“We found that 30 percent of the regions with available data have fully decoupled carbon emissions from economic growth. Regions with high incomes and a history of carbon-intensive industries, as well as those with significant shares of service and manufacturing sectors were particularly successful in reducing carbon emissions while still experiencing economic growth,“ says Anders Levermann, co-author and head of the research department “Complexity Science” at PIK. “A stabilization of the global mean temperature is only possible with net-zero carbon emissions. That ...
Cellular couriers: Body's ‘delivery trucks’ could lead to new cancer blood test
2024-10-28
A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies.
Extracellular vesicles (EVs) are small ‘delivery trucks’ released by our cells that deliver important materials to other cells to aid cellular communication. This study revealed, for the first time, a link between levels of EVs in the blood and tissue damage caused by diseases such as leukaemia.
Researchers hope to leverage the ...
Public and community engagement key to enhancing urban living conditions and environmental decision making in China, study says
2024-10-28
Public and community engagement in decision making is key to enhancing urban living conditions and the environment in China, a new study says.
There has been significant progress through legislation to promote the role of citizens in environment and nature-based solutions (NBS), but progress in involving the public in projects has been limited, the research shows.
However, there has been some work in gathering public opinion and involving them in the project design and decision-making of government-led and large NBS projects.
Researchers found smaller local NBS projects tend to see higher levels of public participation, ...

A new chemistry for CRISPR
2024-10-28
CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision.
But it turns out that CRISPR systems have more than one strategy in their toolkit. A mechanism originally discovered in bacteria, where it has operated as an adaptive immune system for eons, CRISPR is naturally deployed by certain singled-cell organisms to protect themselves against viruses (called phages) and other foreign genetic fragments. Now, researchers at Rockefeller’s Laboratory ...
Giant clam declared critically endangered after the latest assessment
2024-10-28
The giant clam, known for its colorful cape-like mantle, wavy shell and astonishing size, is in danger of going extinct after its population plunged by more than 80% over the last century, according to a new assessment by a University of Colorado Boulder biologist and collaborators.
The assessment, led by Ruiqi Li, a postdoctoral researcher at the CU Museum of Natural History, prompted the International Union for Conservation of Nature (IUCN) today to update the conservation status of this animal from “vulnerable” to ...

Pythons can swallow even bigger prey than scientists realized
2024-10-28
Burmese pythons can consume prey even larger than scientists realized, according to a new study.
That means more animals are on the menu across southern Florida, where the nonnative, invasive snakes have decimated populations of foxes, bobcats, raccoons and other animals.
Pythons swallow deer, alligators and other prey whole. What they eat is limited in part by how big an animal they can wrap their flexible, stretchy jaws around. Researchers call this the snake’s gape.
University of Cincinnati Professor Bruce Jayne said measurements of snakes captured in and around Everglades National Park show that the biggest pythons have an even bigger gape than mathematical ...
Evidence mounts for dark energy from black holes

Almost 14 billion years ago, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of the infant universe and produced all known matter, according to the prevailing inflationary universe theory.
That ancient energy shared key features of the current universe's dark energy, which is the largest mystery of our time by at least one objective standard: It makes up the majority—roughly 70%—of the universe, but scientists ...
AI might scare us, but can we scare it?
2024-10-28
In recent years, advancements in artificial intelligence have enabled intelligent machines to generate visual art, compose music, and create videos. They converse with us, help with homework, and have even begun competing for our jobs. Amid these advances, machines evoke powerful reactions from humans—sparking concerns about control, fairness, and the potential for misuse. Many feel unsettled by the growing presence of intelligent machines when they inadvertently reinforce power imbalances and perpetuate injustices.
Amid all of this disruption and mistrust, we are comforted to know that machines can`t have emotions. Yet, recent advancements in language-based AI have demonstrated ...
