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...

- 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.
One more clue to the Moon's origin
- ScienceDaily
- 22/8/10 22:10
Researchers discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed.
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.
Extreme heat and drought events require more systematic risk assessment
- ScienceDaily
- 22/8/10 22:10
Simultaneous extreme heat and drought events have consequences in a variety of areas -- for example the economy, health and food production. In addition, due to complex socio-economic connections, such extreme events can cause knock-on effects, researchers have shown. More systematic risk assessments are needed to make affected regions more resilient.
Prehistoric podiatry: How dinos carried their enormous weight
- ScienceDaily
- 22/8/10 22:10
Scientists have cracked an enduring mystery, discovering how sauropod dinosaurs -- like Brontosaurus and Diplodocus -- supported their gigantic bodies on land.
Building on the moon and Mars? You'll need extraterrestrial cement for that
- ScienceDaily
- 22/8/10 22:10
Researchers are exploring ways to use clay-like topsoil materials from the moon or Mars as the basis for extraterrestrial cement that could be used by astronauts to create building materials for life in outer space. Scientists have converted simulated lunar and Martian soils into geopolymer cement, which is considered a good substitute for conventional cement.
PET scan visualization can measure effects of STING-activating drugs
- ScienceDaily

A new study suggests that readily available PET scanning could enable a whole-body analysis of the effects of systemic STING-activating therapy in humans, potentially providing a diagnostic tool to guide clinical development of this treatment approach.
New study reveals computation-guided approach to suppressing cancer tumor growth
- ScienceDaily
- 22/8/10 22:10
A new study 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 increase chemical diversity of p53 corrector molecules for clinical development.

Research identifies, exploits vulnerability in certain high-risk cancers
- ScienceDaily
- 22/8/10 18:36
A subset of cancers exist that produce predominantly poor outcomes because their cells employ a mechanism known as alternative lengthening of telomeres (ALT) to maintain telomere length so they can continue to grow and multiply. Telomeres are caps on the end of chromosomes that serve as protectors for the genetic information contained within the cell.
