Simplified CRISPR tools for efficient genome editing and streamlined protocols for their delivery into mammalian cells and mouse zygotes
Genome editing using the CRISPR/Cas9 system requires the presence of guide RNAs bound to the Cas9 endonuclease as a ribonucleoprotein (RNP) complex in cells, which cleaves the host cell genome at sites…[Read more]
A metallo-DNA nanowire with uninterrupted one-dimensional silver array
A metallo–DNA hybrid nanowire composed only of silver-mediated base pairs has been prepared and its crystal structure resolved by X-ray diffraction. The nanowire, which is 2 nm wide and whose length reaches the μm to mm scale, holds silver ions into uninterrupted on…[Read more]
Phonon scattering inhibits simultaneous near-unity efficiency and indistinguishability in semiconductor single-photon sources
The efficiency and indistinguishability of single-photon emission by a quantum dot optically coupled to a microcavity and to a waveguide are theoretically investigated. Owing to unavoidable phonon sideband, they can never…[Read more]
The dissociation of adherent mesenchymal stem cell (MSC) monolayers with trypsin and enzyme-free dissociation buffer was compared. A significantly lower proportion of viable cells were obtained with enzyme-free […]
Small rise in temperatures may cause heavy rain, heat waves
Even a slight rise in global temperatures may lead to extreme weather conditions, say scientists who found that just half a degree Celsius of warming has led to an increase in heat waves and heavy rains across the planet. Researchers compared two 20-year periods 1960-79 and 1991-2010…[Read more]
‘Brain Training’ app found to improve memory in people with mild cognitive impairment
A brain training computer game developed by British neuroscientists has been shown to improve the memory of patients in the very earliest stages of dementia and could help such patients avert some symptoms of cognitive decline. Independent experts said the stu…[Read more]
Terry Gobanga: ‘I was gang-raped on my wedding day’
When Terry Gobanga – then Terry Apudo – didn’t show up to her wedding, nobody could have guessed that she had been abducted, raped and left for dead by the roadside. It was the first of two tragedies to hit the young Nairobi pastor in quick succession. But she is a survivor.
It was going to…[Read more]
Donald Trump tweeted that he’s redefining the social media behaviour of a “modern-day” president. On Sunday he once again proved it.
Mr Trump’s CNN-wrestling video, apparently cribbed from a user on the internet message board Reddit, may be unfamiliar commentary coming from the chief executive of the US, but it’s classic Trump.
He has shown…[Read more]
With advancements in the field of biometric technology, India has topped globally in adoption of biometrics techniques, says a report. “On an average, people in India (9 per cent) are three times more likely than any other country (3 per cent) surveyed to have used ‘iris recognition’ to identify themselves,” said the HSBC’s recent ‘Trust in…[Read more]
