Scientists discover there are way more bugs in California than you thought
Confirmed
In Short: Additionally, scientists at La Jolla Institute for Immunology (LJI) and researchers at the University of California San Diego Moores Cancer Center have discovered a new way to redirect virus-fighting T cells to kill pancreatic tumor cells.
Scientists at UC San Diego have uncovered a previously unknown process that interferes with the liver's ability to clear cholesterol from the blood, potentially leading to new treatment options for patients with high cholesterol levels. The discovery was made using experiments involving mice and human cells, and it highlights a critical piece of the cholesterol regulation puzzle.
Alan Saltiel, PhD, professor of medicine at UC San Diego School of Medicine and director of the UC San Diego/UCLA Diabetes Research Center, explained, 'We've known for a long time that a high-cholesterol diet reduces the liver's ability to clear cholesterol from the blood, but we didn't fully understand why.'
The newly discovered pathway is completely separate from anything that existing drugs target, providing a new opportunity to fill that gap. Saltiel added, 'There's still a real need for new cholesterol-lowering options, since some people can't get to safe levels even with the drugs we have now.'
In a separate discovery, NASA-supported scientists have found an organism that lives at extreme temperatures previously thought impossible for complex life. In the heated waters of California’s Lassen Volcanic National Park, a team of scientists observed an amoeba that can reproduce by division at an astonishing 145 degrees Fahrenheit (63 degrees Celsius), setting a record for the upper temperature limit for all known eukaryotes.
Additionally, scientists at La Jolla Institute for Immunology (LJI) and researchers at the University of California San Diego Moores Cancer Center have discovered a new way to redirect virus-fighting T cells to kill pancreatic tumor cells. Here in Southern California, around 50 percent of people carry CMV, which could impact the effectiveness of these new treatments.
A remarkably preserved fossil from northeastern Spain is giving scientists a rare look at the skin, soft tissues, and possible coloration of an ancient crocodile relative that lived about 125 million years ago. This fossil provides valuable insights into the evolution of these ancient creatures.
Background
Scientists have identified a new dinosaur species, Paludohadros proudlovii, from a fossil discovered in England more than 20 years ago.
Scientists have discovered a giant fungus in China and made other significant scientific breakthroughs.
What's confirmed
- In the heated waters of California’s Lassen Volcanic National Park, a team of scientists observed an amoeba that can reproduce by division at an astonishing 145 degrees Fahrenheit (63 degree Celsius), setting a record for the upper temperature limit for all known eukaryotes.
What's still developing
- Study of the meteorite allowed NASA scientists to determine it was one of roughly 435 from Mars.
- The precise method allowed scientists to analyze single grains of minerals.
- A meteorite found in Mali in 2022 is among the oldest Martian rocks known on Earth, a recent study says, dating back more than 4.1 billion years and offering scientists rare insights into Mars’ ancient crust and water history.
- One of WISE’s main goals was to help scientists understand our galaxy’s youth and the birth of the solar system — and possibly to tell the tale of how it all began.
- Scientists are warning that exposure to deep-space radiation could cause lasting damage to the human heart, raising new concerns about the health risks of sending people to the Red Planet.
- In a new study, scientists revealed that the meteorite fragments collectively form a space rock known as Taghaza 001, named after an ancient abandoned salt-mining settlement in Mali near the discovery site.
- "It is very rare to find something this old," said Yang Liu, a planetary scientist at NASA's Jet Propulsion Laboratory in California and the study's lead author.
- In a recent paper published in Current Biology, a research team led by scientists at the University of California, Santa Cruz, revealed that the so-called “American cheetah” is actually a relative of the Puma, adapted to Arctic conditions.

- By analyzing nuclear paleogenomes and stable isotopes from fossils found as far north as the Yukon, scientists have discovered that this iconic cat was not a true cheetah, but a highly adaptable relative of the puma that specialized in eating fish to survive the Arctic.
