Bird shots: Is vaccinating poultry the best defense against a deadly bird flu?
Lakeside, California—
Hilliker’s Ranch Fresh Eggs in this San Diego suburb has 30,000 chickens in three “cage-free,” open-air barns, where birds crowd the floor like rush-hour riders on a big city subway. “A cage-free aviary is a very interesting science experiment,” says Frank Hilliker, who runs the farm his

Typhoid outbreak on refugee ship in Netherlands traced to raw sewage
Report finds that 72 cases of the disease on the vessel, which was housing asylum seekers, were caused by a wastewater leakA major outbreak of typhoid among asylum seekers living on a ship inthe Netherlands has been traced to raw sewage which was allowed to mix with tanks of freshwater for drinking and cooking.A total of 72 cases of the highly contagious disease were confirmed during the spring 2022 outbreak on the Liberty Ann, an old cruise ship which was being used as emergency accommodation in Haarlem.Continue reading...

UK develops genetic early warning system for future pandemics
Project aims to roll out cheap, easy-to-use technology across the globe to spot emergence of any new health threatsBritish researchers are developing a groundbreaking technology to monitor genetic changes in respiratory viruses as they circulate round the world. The system is to be used to pinpoint dangerous new variants as they emerge and act as an early warning system for new diseases and future pandemics.The team, which is based at the Wellcome Sanger Institute in Cambridgeshire, intends to make the technology cheap, easy to use and capable of being scaled up to provide global surveillance of a wide range of viruses.

Toddler ’s mystery infection traced back to cake-snatching iguana
Three-year-old was on beach in Costa Rica when reptile tried to steal her dessert and bit her handIt could almost be a fable from Aesop, or a story from the Brothers Grimm: the toddler, the lizard and the cake. But for one small child, whose baked treat was snatched by an iguana, it was a tale with a twist.Doctors have revealed that the toddler ended up with an unusual infection after being bitten by the reptile as it tried to steal a bite of cake.Continue reading...

No kittens required: Scientists find new way to study toxoplasmosis parasite in lab
One of the most widespread parasites on the planet can also be one of the most difficult to study.
Toxoplasma gondii
—a single-celled protozoan—is capable of infecting almost every mammal and bird species,
including humans
, and in severe cases causes blindness, birth defects, and death. Yet it only sexually reproduces inside the intestines of domestic cats and other members of the Felidae family, prompting controversial studies on kittens.
Now, a research team has come up with a technique that uses gene editing of
Toxoplasma
to push the parasite toward sexu...

Bheed review – lockdown thriller cuts across India’s class conflict
A tense, state-of-the-nation drama set in Covid-era India successfully exposes how the caste system underpins much of the country ’s division and strife‘No one ever plans for the poor,” says a young police officer in this tense, painful pandemic drama from India. Shot in black and white, it’s set at the start of the government-imposed lockdown in May 2020 that led to the exodus of 10 million migrant workers from India’s cities. The police o fficer has been put in charge of a rural roadblock to stop poor workers returning to their families and villages – preventing the spread of the virus. But realising that no ...

When it comes to identifying new gene therapies, she ’s in it for the long run
Like any experienced distance runner, Grace McAuley always keeps her focus on the finish line — even if it’s out of sight. That’s what makes her such a promising young scientist.In spring 2021, McAuley was a UCLA senior who was wrapping up four years on the Bruin track and cross-country teams. Not long after running her last race for UCLA, she joined the lab of Dr. Donald Kohn, a UCLA physician-scientist known for developing gene therapies for blood and immune disorders.“I kept telling Grace she was too busy to join the lab, but she wouldn’t take no for an answer,” says Kohn, a member of theEli and Edythe Broad...

Gut feelings: why drugs that nurture your microbes could be the future of mental health
Scientists know our gut influences our brain. So psychobiotic drugs that shift the composition of microbes in the gut may be able to help treat disorders such as anxiety and depressionIna classic comic strip, most recently gracing the Beano, tiny characters called “numskulls” live in the head of a chap called Edd, controlling what he gets up to – often with hilarious results. It has run for decades, presumably because the idea that there could be critters within us capable of exerting a profound mental and physical influence seems pretty absurd.But it appears science is having the last laugh: in recent years the idea...

Newly released Chinese Covid data points to infected animals in Wuhan
Previously unseen genomic samples suggest animals at Huanan market were potential sourceNewly released data from early in the Covid-19 pandemic has offered a crucial insight into the outbreak ’s origins, suggesting that Covid-infected animals were present at a market in Wuhan and could have been a “potential source of human infections”.A pre-print report on Monday by a team of international researchers fleshed out analysis of previously unseen genomic samples collected by Chinese scientists at the Huanan market in Wuhan in the early days of the pandemic.Continue reading...

UCLA-led study uses base editing to correct mutation that causes rare immune deficiency
Key takeawaysA condition called CD3 delta SCID is caused by a mutation in the CD3D gene, which prevents the production of the CD3 delta protein that is needed for the normal development of T cells from blood stem cells.UCLA researchers showed that a new genome editing technique called base editing can correct the mutation that causes CD3 delta SCID in blood stem cells and restore their ability to produce T cells.Base editing is an ultraprecise form of genome editing that enables scientists to correct single-letter mutations in DNA.A new UCLA-led study suggests that advanced genome editing technology could be used as a ...
