200 times faster than ever before: The speediest quantum operation yet

Added: 17.07.2019 23:18 | 3 views | 0 comments

A group of physicists at UNSW Sydney have built a super-fast version of the central building block of a quantum computer. The research is the milestone result of a vision first outlined by scientists 20 years ago.

Vast snow cannons could be used to repair the West Antarctic ice sheet and prevent catastrophic sea level rise, leading climate scientists have suggested. Seawater could be turned into ice and then pumped onto the glacier, generating trillions of tonnes of additional snowfall, which researchers believe could – in theory – stave off the complete collapse of the West Antarctic ice sheet. If this collapse were to happen, global sea levels could rise by more than three metres, submerging low-lying global metropolises such as London, New York and Shanghai. We’ll tell you what’s true.

Scientists have wiped out the entire population of mosquitoes on two islands in southern China using radical techniques to render the males infertile, according to a new study that could transform the fight against a range of deadly diseases.Over the course of less than two years, scientists released more than 200 million specially bred male Asian tiger mosquitoes on Shazai and Dadaosha islands in the delta to the south of Guangzhou city, the area that has the highest number of dengue fever… ......

Making cancer stem cells visible to the immune system

Added: 17.07.2019 22:17 | 13 views | 0 comments

Leukemia stem cells protect themselves against the immune defense by suppressing a target molecule for killer cells. This protective mechanism can be tricked with drugs. Scientists now describe a new therapeutic approaches that can possibly be derived from these results.

Cell types affected in brains of multiple sclerosis patients pinpointed

Added: 17.07.2019 22:17 | 8 views | 0 comments

Scientists have discovered that a specific brain cell known as a 'projection neuron' has a central role to play in the brain changes seen in multiple sclerosis (MS). The research shows that projection neurons are damaged by the body's own immune cells, and that this damage could underpin the brain shrinkage and cognitive changes associated with MS. These new findings provide a platform for specific new MS therapies that target damaged brain cells to be developed.

How the brain distinguishes between voice and sound

Added: 17.07.2019 21:18 | 12 views | 0 comments

Is the brain capable of distinguishing a voice from phonemes? Researchers devised pseudo-words spoken by three voices. Their aim? To observe how the brain processes this information when it focuses either on the voice or phonemes. The scientists discovered that the auditory cortex amplifies different aspects of the sounds, depending on what task is being performed. Voice-specific information is prioritized for voice differentiation, while phoneme-specific information is important for the differentiation of speech sounds.

New insight into microRNA function can give gene therapy a boost

Added: 17.07.2019 21:18 | 8 views | 0 comments

Scientists have shown that small RNA molecules occurring naturally in cells, i.e. microRNAs, are also abundant in cell nuclei. Previously, microRNAs were mainly thought to be found in cytoplasm. The scientists also discovered that microRNA concentrations in cell nuclei change as a result of hypoxia. The findings strongly suggest that microRNAs play a role in the expression of genes in the cell nucleus.

Megakaryocytes act as 'bouncers' restraining cell migration in the bone marrow

Added: 17.07.2019 21:18 | 6 views | 0 comments

Scientists found that megakaryocytes act as 'bouncers' and thus modulate bone marrow niche properties and cell migration dynamics.
