Appeal to identify ‘La Botaniste’ who slipped from history

Appeal to identify ‘La Botaniste’ who slipped from history

Science
RHSWhen sorting through books gathering dust in the attic, it's common to find mementos of the past such as a poem, a pressed-flower, or a letter.But when staff at the Royal Horticultural Society (RHS) went through hundreds of old plant books, they stumbled on a collection of botanical treasures the likes of which they'd never seen before.Tucked inside a copy of The English Flora from 1830 were poems, doodles, plant specimens and a cartoon.Judging by the contents, the owner was a keen plants woman. But her name, Isabella A Allen, appears to have slipped from history.She may be the early 19th Century botanical illustrator about which little is known. Or she could be among the legions of uncelebrated 19th Century women with a passionate interest in plants.Either way, the RHS is hoping to tra...
Scientists identify brain signals of fading consciousness during anesthesia, sleep

Scientists identify brain signals of fading consciousness during anesthesia, sleep

Science
Dec. 29 (UPI) -- What happens inside the human brain when consciousness fades away during anesthesia and normal sleep? Scientists have long estimated that the answer to such a question might provide clues to the neurological origins of consciousness. Until now, researchers had struggled to separate the brain patterns associated specifically with the loss of consciousness and the more generalized neural effects of falling asleep or being put to sleep. Advertisement For the first time, scientists have successfully isolated the specific brain changes related to losing or gaining consciousness. For the study, published this week in the Journal of Neuroscience, researchers used positron emission tomography, or PET scans, to monitor the brain activity of healthy volunteers experiencing differen...
Scientists identify possible origin of free will

Scientists identify possible origin of free will

Technology
The concept of free will is fundamental to human society - our legal systems are dependent on it - but neuroscientists have struggled to identify it in the human brain.Modern science poses a profound philosophical problem: If the laws of physics govern the brain's electrical activity then how can free will actually exist? And if free will doesn't exist, how can individuals be held accountable for their actions?Brain signals known as readiness potential (RP) which scientists believe proceed not only voluntary movements but also the intention to move, are one of the strongest arguments against the existence of free will.[embedded content] Other researchers have countered that RP signals may simply be an artefact of measurement and not actually something which determines the choices we believ...
HDFC to tap Egon Zehnder to identify Aditya Puri’s successor

HDFC to tap Egon Zehnder to identify Aditya Puri’s successor

Finance
MUMBAI: India's HDFC Bank will retain global executive search firm Egon Zehnder to find a successor to managing director Aditya Puri, four sources familiar with the matter said, as its board seeks to end an impasse and zero in on a candidate. The board's decision to recruit a global head-hunting firm comes as a six-member internal search committee, appointed in November last year, has not been able to reach a consensus on selecting a successor to Puri, who has been at the helm of the country's largest private lender since its inception in 1994. Puri, whose term comes to an end in October this year, is also an advisor to the search committee tasked with identifying a suitable candidate. "The latest decision to hire a global advisory firm has been taken after the search committee members rea...
Neuroscientists build model to identify internal brain states

Neuroscientists build model to identify internal brain states

Science
Nov. 25 (UPI) -- How humans respond to stimuli depends on not only external factors, but internal variables like mood and memory, as well. These internal brain states are invisible to the outside observer, but neuroscientists have developed a new model to predict internal brain states based on observations of outward behavior. For now, the model only works to predict the internal states of fruit flies, but it could eventually be used to better understand the relationship between human brain states and behavior. During a previous study, scientists were able to predict a portion of a male fruit fly's singing behavior by observing the insect's behavior. With the help of the new model, scientists can more accurately predict the fruit fly's seduction methods. "By estimating the fly's interna...
