Lights may be enjoyed from Tasmania and New Zealand, experts say, but also as far north as Sydney and Perth

Skywatchers may be treated to a celestial delight on Wednesday evening, with a severe solar storm making it possible to view the southern lights across large parts of Australia – possibly including Sydney and Perth.
An intense geomagnetic storm, caused by several powerful bursts of energy from the sun, has led the Bureau of Meteorology’s space weather forecasting centre to issue an aurora alert for “mid to southern parts of Australia”.

Animal behaviourists tested 61 gulls in Cornwall to find most effective method of countering feathery threat
Some people respond to the unwanted attentions of a gull eyeing up a bag of chips or a Cornish pasty by frantically flapping their hands at the hungry bird while others beat a rapid retreat into the nearest seaside shelter. But researchers have found that a no-nonsense yell – even a relatively quiet one – may be the best way to get rid of a pesky herring gull.
Animal behaviourists from the University of Exeter tried to establish the most effective method of countering a feathery threat by placing a portion of chips in a place where gulls were bound to find them.

Scientists believe new discovery to be the oldest crocodilian eggshells ever found in Australia

Scientists have identified what are believed to be the oldest crocodilian eggshells ever found in Australia, unearthed in a grazier’s back yard in regional Queensland.
The 55m-year-old eggshells – found at a fossil deposit in Murgon, approximately 270km north-west of Brisbane – likely belong to a group of extinct crocodiles known as mekosuchines, new research suggests.

L'article Les rythmes biologiques cellulaires au cœur d’une nouvelle piste thérapeutique contre Alzheimer est apparu en premier sur Fredzone.A regenerative scheme has shown early promise, with herders hopeful it can restore degraded pastures
Ibrahima Ka, dressed in flowing indigo robes, gathers his herd with those of his neighbours before a stretch of lush, untouched pasture. The bellowing, heaving and trampling of 350 impatient zebu cows behind a wire perimeter marks a break with centuries of herding tradition in Senegal, west Africa. Rather than roaming freely across the country’s vast grasslands, shepherds tightly pack the herd together, confining them to graze in short, intensive bursts before being moved to a new plot.
Ka, the village chief of Thignol, is spearheading the first pilot of “mob grazing” in Senegal, aiming to mimic, on a much smaller scale, how wildebeest flow across the Serengeti, moving to protect themselves against lions and cheetahs. The idea that intense grazing can regenerate grasslands rather than accelerate their decline has been controversial. Initially, proponents argued it could help to solve the climate crisis through storing carbon in regenerated grasslands – a claim with little scientific basis. But there is some evidence that the method can boost biodiversity and grassland health in dry areas such as Senegal.

New funding for researchers and streamlined regulation part of roadmap for phasing out use of animals in science
Animal testing in science would be phased out faster under a new plan to increase the use of artificial intelligence and 3D bioprinted human tissues, a UK minister has said.
The roadmap unveiled by the science minister, Patrick Vallance, backs replacing certain animal tests that are still used where necessary to determine the safety of products such as life-saving vaccines and the impact pesticides have on living beings and the environment.

The species – dubbed Megachile (Hackeriapis) lucifer – was found in the state of Western Australia, Curtin University announced on Tuesday.
