- 21/7/28 21:44
Using advanced imaging technology, scientists have provided an unprecedented understanding of the BRCA1-BARD1 protein complex, which is often mutated in patients with breast or ovarian cancer. Their paper identifies aspects of how BRCA1-BARD1 functions, supporting future translational research, cancer prevention efforts and drug development.
‘Less than 1% probability’ that Earth’s energy imbalance increase occurred naturally
- ScienceDaily
- 21/7/28 21:03
Sunlight in, reflected and emitted energy out. That's the fundamental energy balance sheet for our planet -- and for decades, it has been out of balance. The extra energy manifests as higher temperatures, rising sea levels, floods, droughts, more powerful blizzards and hurricanes, and deadlier extreme events. Not only is the imbalance growing, but there's a 99% chance that the growth is due to...
Seeking a unique treatment for lobular breast cancer

Does testosterone influence success? Not much, research suggests
- ScienceDaily
- 21/7/28 20:03
With the Olympics underway, higher testosterone has often been linked to sporting success, and other kinds of success too. But beyond sport, new research has found little evidence that testosterone meaningfully influences life chances for men or women. In fact, the study suggests that despite the social myths surrounding testosterone, it could be much less important than previously thought.
Neanderthal and Denisovan blood groups deciphered
- ScienceDaily
- 21/7/28 20:03
The blood groups of three Neanderthals one Denisovan have been determined by a team including a palaeoanthropologist, population geneticists, and haematologists. Their research provides new data for understanding the origins, history, and health of these extinct hominin lineages.
Climate adaptation at the U.S. Department of Defense and beyond
- ScienceDaily
- 21/7/28 18:43
New research identifies climate change challenges faced by U.S. Department of Defense facilities, and solutions that might serve as a model for other large organizations.
Water as a metal
- ScienceDaily
- 21/7/28 18:43
Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used a completely different approach to produce metallic water and documented the phase transition at BESSY II.
Scientists capture most-detailed radio image of Andromeda galaxy to date
- ScienceDaily
- 21/7/28 17:13
Scientists have published a new, detailed radio image of the Andromeda galaxy -- the Milky Way's sister galaxy -- which will allow them to identify and study the regions of Andromeda where new stars are born.
Managing earthquakes triggered by oil production

A team of scientists has developed an approach to disposing wastewater that reduces the danger of triggering an earthquake.
Biomedical scientists tie improved learning processes to reduced symptoms of depression
- ScienceDaily
- 21/7/28 17:13
Brain imaging and mathematical modeling reveal previously unreported mechanistic features of symptoms associated with major depressive disorder.
Superconductivity in high-Tc cuprates: ‘from maximal to minimal dissipation’ - a new paradigm?
- ScienceDaily
- 21/7/28 17:13
Researchers used some of Europe's strongest continuous magnetic fields to uncover evidence of exotic charge carriers in the metallic state of copper-oxide high-temperature superconductors (high-Tc cuprates). The team postulated that it is these exotic charge carriers that form the superconducting pairs, in marked contrast with expectations from conventional theory.
Man's new best friend: What cats can teach us about human genetics and precision medicine
- ScienceDaily
- 21/7/28 17:13
Although cats have lived alongside humans for millennia, it remains a dogs' world. This bias has historically bled into science as well. It's time for cats to get their day, argues veterinary medicine experts. Cats, they say, have the potential to be a valuable model organism for geneticists, as the feline genome is ordered similarly to humans.
A caffeine buzz helps bees learn to find specific flowers
- ScienceDaily
- 21/7/28 17:13
Researchers have shown that feeding bumble bees caffeine helps them better remember the smell of a specific flower with nectar inside. While previous studies have shown that bees like caffeine and will more frequently visit caffeinated flowers to get it, this study shows that consuming caffeine in their nest actually helps bees find certain flowers outside of the nest.
Researchers develop 'dimmer switch' to help control gene therapy
- ScienceDaily
- 21/7/28 17:13
In a major advancement in the field of gene therapy for rare and devastating diseases, researchers have developed a "dimmer switch" system that can control levels of proteins expressed from gene therapy vectors. The system is based on alternative RNA splicing using an orally available small molecule and works effectively in tissues throughout the body, including the brain.
