Nearly a hundred genes have been lost during the woolly mammoth's evolution
A new study shows that 87 genes have been affected by deletions or short insertions during the course of the mammoth's evolution. The researchers note that their findings have implications for international efforts to resurrect extinct species, including the woolly mammoth. The study was published today in the journal iScience by researchers at the Centre for Palaeogenetics in Stockholm, a...
Looking for 'ever-loving homes': Nearly 4,000 beagles bred for drug experiments rescued
In what's thought to be one of the biggest dog rescue efforts in the U.S., nearly 4,000 beagles are looking for forever homes after being saved from a Virginia facility that bred them to be sold to laboratories for drug experiments.
New study reveals computation-guided approach to suppressing cancer tumor growth
A new study, led by researchers from the University of California, Irvine and the University of California, San Diego, reveals a new computation-guided approach to identify small molecules that can restore aspects of wild-type p53 tumor suppression function to mutated p53, which play an important role in many human cancers. This approach was successful both in vitro and in vivo. This strategy can...
Meteor shower, supermoon will brighten Thursday's night sky—but that's a problem
Those who enjoy watching the skies will see two events later this week collide: A supermoon will compete with the Perseid meteor shower to light the night.
How bacteria defuse hypothiocyanite, an antimicrobial weapon of the innate immune system
How do a wide variety of bacteria—both pathogenic and commensal—survive antimicrobials released by the mammalian innate immune system?
New research reveals the circadian clock influences cell growth, metabolism and tumor progression
In a new University of California, Irvine-led study, researchers define how the circadian clock influences cell growth, metabolism and tumor progression. Their research also reveals how disruption of the circadian clock impacts genome stability and mutations that can further drive critical tumor-promoting pathways in the intestine.
Scientists identify mechanism crucial for COVID-19 virus replication
A team led by UT Southwestern researchers has identified how SARS-CoV-2, the virus that causes COVID-19, builds a structure called the RNA cap that's critical for successful viral replication. The finding, published in Nature, could lead to new strategies to attack COVID-19, which has sickened nearly 600 million and killed more than 6 million worldwide thus far.
Going deep: New ground motion model more accurately simulates earthquakes, explosions
Lawrence Livermore National Laboratory (LLNL) scientists have created a new adjoint waveform tomography model that more accurately simulates earthquake and explosion ground motions. The paper, published in the Journal of Geophysical Research: Solid Earth, was selected for an Editor's Highlight.
NASA's Fermi telescope confirms star wreck as source of extreme cosmic particles
Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA's Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place.
Building on the moon and Mars? You'll need extraterrestrial cement for that
Sustained space exploration will require infrastructure that doesn't currently exist: buildings, housing, rocket landing pads.

Leisure activities, such as reading a book, doing yoga and spending time with family and friends, may help lower the risk of dementia, according to a new meta-analysis. The meta-analysis reviewed available studies on the effects of cognitive activities, physical activities, and social activities and the risk of dementia.
Quality of life with multiple sclerosis may depend on several factors
- ScienceDaily
- 22/8/10 22:11
Quality of life is a measure of a person's level of comfort, health and happiness. For people with multiple sclerosis (MS), a new study has found there are specific factors that may affect a person's physical and mental quality of life.
Secret behind 'nic-sickness' could help break tobacco addiction
- ScienceDaily
- 22/8/10 22:11
Nicotine activates the dopamine reward network in the brain, but at high doses it also activates a parallel aversive dopamine network. This discovery and identification of the nicotine receptor responsible for the negative effects of high-dose nicotine provides a target for drug developers. In the future, therapeutics could tweak the network to make nicotine aversive at lower doses in order to...

- ScienceDaily
- 22/8/10 22:10
Researchers have developed a technique to 3D-print materials with customizable mechanical properties that can also sense how they are moving and interacting with their environment. Their method only requires one printing material and a single run on a 3D printer.
Scientists discover antibodies that induce broad immunity against SARS viruses, including emerging variants
- ScienceDaily
- 22/8/10 22:10
Scientists have identified antibodies that are effective against many different SARS-CoV-2 variants, as well as other SARS viruses like SARS-CoV-1, the highly lethal virus that caused an outbreak in 2003. The results showed that certain animals are surprisingly more able to make these types of 'pan-SARS virus' antibodies than humans, giving scientists clues as to how to make better vaccines.

New target identified for treatment of premature aging disease
- ScienceDaily
- 22/8/10 22:10
A stretch of DNA that hops around the human genome plays a role in premature aging disorders, scientists have discovered. In people with early aging, or progeria, RNA encoded by this mobile DNA builds up inside cells. What's more, the scientists found that blocking this RNA reverses the disease in mice. The findings focus on a piece of RNA known as LINE-1.
