First known gene transfer from plant to insect identified

Posted by in categories: biotech/medical, chemistry, genetics

“The results were surprising, but convincing, says Yannick Pauchet, a molecular entomologist also at the Max Planck Institute for Chemical Ecology. ” According to the data they provide, horizontal gene transfer is the most parsimonious explanation,” he says.

But how the whitefly managed to swipe a plant gene is unclear. One possibility, says Turlings, is that a virus served as an intermediate, shuttling genetic material from a plant into the whitefly genome.

As researchers s… See More.

COVID-19 Is Different Now

Posted by in categories: biotech/medical, health

COVID-21 is the product of all these changes in aggregate. It’s the disease as it will be experienced in the months and years to come: with new variants of the virus, new public policies and health behaviors, various degrees of immune memory, and—most important—a cavalcade of new vaccines.

One-quarter of all Americans have now received at least one shot, and that number is racing up. This month, New Yorkers lined up outside Yankee Stadium throughout the night at a makeshift 24/7 vaccination site, until the supply ran out. “If we open 3000 appointments, they will immediately fill,” says Ramon Tallaj, a physician who oversees clinical care in underserved communities across New York City. Demand seems to be growing. If there were sufficient supply, Tallaj told me, his team could be giving out 40000 doses every day. And this should happen soon; the White House says that shortages will end in the coming weeks.

The vaccination effort is sure to change the nature of COVID in unexpected ways. The habitat for the virus is changing: It may still stick in the nasal passages of an immunized person, but it shouldn’t continue on its way into the lungs, much less the toes. The key question is just how long this protection will last, especially against a rapidly mutating virus. Clinical trials have shown the vaccines to be fantastic at preventing serious illness so far, but haven’t yet been able to observe how protection might dissipate over long periods.

A DNA Sequencing Revolution Helped Us Fight Covid. What Else Can It Do?

Posted by in categories: biotech/medical, health

And unexpectedly, Covid-19 has proved to be the catalyst. “What the pandemic has done is accelerate the adoption of genomics into infectious disease by several years,” says deSouza, the Illumina chief executive. He also told me he believes that the pandemic has accelerated the adoption of genomics into society more broadly — suggesting that quietly, in the midst of chaos and a global catastrophe, the age of cheap, rapid sequencing has arrived.


Ultrafast and ultracheap sequencing could reshape the future of health care.

“Zombie” Cells? Research Shows Some Genes Come to Life in the Brain After We Die

Posted by in categories: biotech/medical, neuroscience

Post-mortem changes may shed light on important brain studies.

In the hours after we die, certain cells in the human brain are still active. Some cells even increase their activity and grow to gargantuan proportions, according to new research from the University of Illinois Chicago.

In a newly published study in the journal Scientific Reports, the UIC researchers analyzed gene expression in fresh brain tissue — which was collected during routine brain surgery — at multiple times after removal to simulate the post-mortem interval and death. They found that gene expression in some cells actually increased after death.

San Francisco to pay ‘essential’ artists $1,000 per month basic income in pilot program amid pandemic

Posted by in categories: biotech/medical, economics

“The Office of Racial Equity at the San Francisco Human Rights Commission will handle the program and artists from ”historically marginalized communities” are encouraged to apply.

Other basic income programs under development in San Francisco include funds for emergency medical technicians and Black and Pacific Islander expectant mothers, FOX 2 reported.


You could call it art for art’s sake — plus $1000 a month.

Astronomers’ Polarized Image Shows Magnetic Fields at the Edge of M87’s Black Hole

Posted by in category: cosmology

MIT Haystack Observatory is one of the 13 stakeholder institutions that constitute the Event Horizon Telescope (EHT) collaboration, which produced the first-ever image of a black hole. The EHT revealed today a new view of the massive object at the center of the M87 galaxy: how it looks in polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.

Haystack Research Scientist Vincent Fish says “Hundreds of people around the world in the EHT collaboration, including scientists and engineers at Haystack, have worked very hard to investigate the role of magnetic fields in shaping jets around black holes. Can magnetic fields build up and dominate over the intense pull of gravity? Our data provide an answer.”

Recyclable ‘veggie’ battery could power future devices more efficiently

Posted by in categories: computing, mobile phones, nanotechnology, sustainability, transportation

A new type of 3D-printed battery which uses electrodes made from vegetable starch and carbon nanotubes could provide mobile devices with a more environmentally-friendly, higher-capacity source of power.

A team of engineers led from the University of Glasgow have developed the battery in a bid to make more sustainable batteries capable of storing and delivering power more efficiently. The battery’s design and fabrication is outlined in a paper published in the Journal of Power Sources.

Lithium-ion batteries provide a useful combination of lightweight, compact form factors and the ability to withstand many cycles of charging and discharging. That has made them ideally suited for use in a wide array of devices, including laptops, mobile phones, smart watches, and electric vehicles.
