Why rescuing the climate and saving biodiversity go hand in hand

Why rescuing the climate and saving biodiversity go hand in hand

×By. Rising sea temperatures are killing corals faster than they can recover. As temperatures continue to increase, more and more of the reef will die, along with the rich variety of life and that depend on it.It is one headline-grabbing example among many. The continued rapid warming of the planet would wipe out many species, even if it were the only change happening. As it is, a sixth in Earth’s history is already under way as farms replace forests and factory ships overfish the oceans.AdvertisementThe heating of the planet will push many struggling species over the brink. Some will just...

Sponges can survive massive doses of radiation without getting cancer

Sponges can survive massive doses of radiation without getting cancer

×BySponges can live for thousands of years, grow continuously and lack an immune system, so they should be particularly prone to cancers. But sponges exposed to X-rays have survived 100 times the lethal dose for humans without tumours.“They seem to be extraordinarily resistant to radiation,” says Angelo Fortunato at Arizona State University. In fact, have the highest level of radiation resistance ever observed in any animal whose cells keep dividing throughout its lifetime – as opposed to creatures like tardigrades whose cells stop dividing.Fortunato’s team has been studying …Existing...

CRISPR doubles lifespan of mice with rapid ageing disease progeria

CRISPR doubles lifespan of mice with rapid ageing disease progeria

×has been used to more than double the lifespan of mice engineered to have , also greatly improving their health.The results far surpassed expectations. Progeria affects many different organs in the body, and the team behind the work didn’t expect that correcting the mutation in a relatively low proportion of cells – 10 to 60 per cent – would have such a big effect. “We were quite amazed,” says .Hutchinson-Gilford progeria syndrome is a rare condition caused when a mutation, which probably took place in the testes or ovaries of a child’s parents, results in a single DNA letter change in one...

Ancestor of pterosaurs might have been a tree-climbing reptile

Ancestor of pterosaurs might have been a tree-climbing reptile

×We finally have a clearer picture of how pterosaurs – a group of extinct flying reptiles – first evolved. The creatures shared dozens of key traits with a long-extinct group of dinosaur-like reptiles that might have been skilled tree climbers, according to a new analysis.Pterosaurs evolved about 220 million years ago and for around 160 million years, until they went extinct along with . Yet figuring out which group of reptiles they evolved from has been difficult.“They appear in the fossil record with fully developed wings and all the modifications associated with flight,” says Martín...

DeepMind's AI biologist can decipher secrets of the machinery of life

DeepMind's AI biologist can decipher secrets of the machinery of life

×An developed by has achieved the long-sought-after goal of accurately predicting the shape of proteins from their sequence alone, a key part of understanding how the machinery of life works. In a competition, AlphaFold was able to match two-thirds of the results achieved by humans doing expensive and time-consuming lab experiments.“I was really wowed when I saw it,” says John Moult at the University of Maryland, one of the competition’s organisers. “This is the first time we’ve come close to approaching experimental usefulness, which is pretty extraordinary.”Proteins are vital for life....

Living electrodes for linking brains to computers tested in rats

Living electrodes for linking brains to computers tested in rats

דLiving electrodes” made of nerve cells genetically modified to respond to light have been successfully implanted in the brains of animals. The hope is that they will provide a better and longer-lasting way to link brains with computers than conventional electrodes.“It allows our technology to be speaking the language of the nervous system, instead of electrical jolts, which is what is done now,” says Kacy Cullen at the University of Pennsylvania. “When our implanted neurons are activated, the deeper part of the brain they are connected to then becomes activated by a natural synaptic...

Pfizer covid-19 vaccine may not need to be kept at -70°C after all

×There may be no need to keep and other similar vaccines at -70°C, potentially making it much easier to distribute them across the world. Two other teams using the same messenger RNA (mRNA) technology for their vaccines have found that they remain stable for at least three months in a normal fridge.The Pfizer and BioNTech vaccine candidate generated great excitement around the world this week when the companies announced that it appears to be more than …Existing subscribers, please with your email address to link your account access.Paid annually by Credit CardInclusive of applicable taxes...

Hearing restored in rats by modifying ear cells to respond to light

Hearing restored in rats by modifying ear cells to respond to light

×Cochlear implants that restore hearing could be improved by genetically modifying the nerve cells in people’s ears so that they respond to light instead of electricity, a study in rats has shown.“This is so much better than what we currently have with electrical implants,” says Tobias Moser at the University Medical Center Göttingen in Germany.Our hearing relies on hair cells inside the cochlea of our ears detecting sounds of different frequencies and then stimulating the right auditory nerve cells. Damage to these hair cells is a common cause of deafness.AdvertisementCochlear implants can...
