She built a model overnight that would guide S.F.’s pandemic response. Now, she predicts our COVID future

 

San Francisco was a few days into sheltering in place in March 2020 when Dr. Maya Petersen got a surprising and urgent request: Health officials wanted to know whether she could put together a model that would help them forecast what was shaping up to be a horrifying pandemic.

A/B Testing Foreign Aid

Seeking innovative ideas for revamping the United States' foreign aid programs, the U.S. Agency for International Development (USAID) conducted an A/B test in rural areas of Rwanda to compare the public welfare results of traditional interventions with simple cash transfers. A control group received no assistance. To conduct the study, they recruited a number of external partners, including Berkeley's Center for Effective Global Action. The agency released the results Thursday, and -- essentially -- the cash transfers worked, with larger cash transfers boosting household's assets, savings, and ability to buy more varied food. The children in those houses were "taller, weighed more, and were less likely to die early," according to the reporter.

Now Fully Complete, Human Genome Reveals New Secrets

A three-year-old consortium has finally filled in remaining DNA, providing the first complete, gapless genome sequence for scientists and physicians to refer to. The newly completed genome, dubbed T2T-CHM13, represents a major upgrade from the current reference genome, called GRCh38, which is used by doctors when searching for mutations linked to disease, as well as by scientists looking at the evolution of human genetic variation.

A Survey of 30,000 Household Reveals COVID-19's Economic Toll in the Developing World

Even in the richest countries in the world, the pandemic has devastated millions. Developing countries have faced the same challenges with far fewer resources to absorb them with. How have their people fared? A new paper aims to solve that problem in the most direct way possible — by surveying tens of thousands of people in developing countries about what COVID-19 has been like for them. The paper, co-authored by UC Berkeley's Edward Miguel gives us a new window into what it has been like to live through 2020 in Bangladesh, Burkina Faso, Colombia, Ghana, Kenya, Nepal, the Philippines, Rwanda, and Sierra Leone. For more on this, see our press release at Berkeley News.

The Pandemic Pushed This Farmer Into Deep Poverty. Then Something Amazing Happened.

In low-income countries, identifying people who have fallen on hard times due to the pandemic is no easy task. Governments don't have good data about who is poor. Togo turned to artificial intelligence: a computer program that dives into data to pinpoint pockets of poverty. The government partnered with researchers at the University of California, Berkeley, and the U.S. charity GiveDirectly to use satellite imagery and mobile phone data to find citizens most in need. The program used mobile phone technology to quickly distribute $22 million in three monthly mobile phone payments to 600,000 citizens in urban parts of Togo: $20 for men and $22 for women.

Huge Study of Coronavirus Cases in India Offers Some Surprises to Scientists

A UC Berkeley study has found several surprising insights on how COVID-19 is affecting India, a country of 1.3 billion people. The median hospital stay before death from the virus was five days, compared with two weeks in the United States, possibly because of limited access to health care. The trend in increasing deaths with age seemed to drop off after age 65, perhaps because Indians who live past that age tend to be relatively wealthy and have access to good health care. The study also found that children of all ages can become infected and spread the virus to others. An overwhelming majority of coronavirus cases globally have occurred in resource-poor countries, noted Joseph Lewnard, an epidemiologist at the University of California, Berkeley, who led the study. But most of the data has come from high-income countries. "It still surprises me that it took until this point for a lot of data to come out of a low- or middle-income country about the epidemiology of Covid," he said.

A New Study Finds That Giving Kids Deworming Treatment Still Benefits Them 20 Years Later

Twenty years after a mass effort in Kenyan schools to treat children for common intestinal parasites, researchers including UC Berkeley's Edward Miguel returned to the original Kenyan sample where they'd first discovered the potentially life-changing impacts of mass deworming campaigns. Following up with the original participants 20 years later, they wanted to answer the question: Are the benefits they initially discovered from childhood deworming treatment - which included more time in school and higher adult incomes - still showing up? For more on this, see our press release at Berkeley News.

Treating children for worms yields long-term benefits, says new study

Children who receive sustained treatment against common parasitic infections grow up to achieve a higher standard of living, with long-lasting health and economic benefits extending to their communities, according to new findings from a research team led by a University of California, Berkeley, economist.

Tales from 141,430 and one genomes

Analysis of the world’s largest set of genome data from pregnant women, totaling 141,431 expectant mothers from across China, has uncovered unsuspected associations between genes and birth outcomes, including the birth of twins and a woman’s age at first pregnancy.

Blood tests reveal broad extent of Zika infection

A new study shows that nearly half of the population of Managua, Nicaragua, has been infected with the Zika virus. Previous infection with the Zika virus imparts immunity to the disease and can help quell future outbreaks.

Amid flu epidemic, more bad news about its spread

Getting lots of sleep, drinking lots of water, sneezing into the crook of your arm and getting a vaccination no doubt will help fight back the flu. But if you don’t want to get it in the first place, don’t breathe.

The yin-yang of cancer and infectious disease

Doctors have had great success using vaccines to boost the immune system to fight infectious diseases like smallpox and measles, but only recently have immune system boosters been tried against cancer.

Aiding Cells’ Strategy to Survive

The Bakar Fellows Program supports James Hurley’s research to develop a drug that can help neurons and other cells clear out debris – a process essential for cell survival.

Genome engineering paves way for sickle cell cure

A team of physicians and laboratory scientists has taken a key step toward a cure for sickle cell disease, using CRISPR-Cas9 gene editing to fix the mutated gene responsible for the disease in stem cells from the blood of affected patients.

Faster, more efficient CRISPR editing in mice

UC Berkeley scientists have developed a quicker and more efficient method to alter the genes of mice with CRISPR-Cas9, simplifying a procedure growing in popularity because of the ease of using the new gene-editing tool.

Translating Genes’ Instructions

Sackler Sabbatical Exchange recipient Hiten Madhani studies how genome cutting machines in cells, called spliceosomes, are able to pluck genes away from other sequences of “letters” in strands of RNA.

Copper: A new player in health and disease

Chris Chang, who is part of the Sackler Sabbatical Exchange Program, carries out experiments to find proteins that bind to copper and may influence the storage and burning of fat.

Do gut microbes shape our evolution?

Scientists increasingly realize the importance of gut and other microbes to our health and well-being, but one UC Berkeley biologist is asking whether these microbes — our microbiota — might also have played a role in shaping who we are by steering evolution.

CRISPR-Cas9 helps uncover genetics of exotic organisms

The simplicity of CRISPR-Cas9 gene editing will soon make studying the genes of any organism, from the simplest slime mold to the octopus, as easy as it now is to study the genes controlling development in standard lab animals such as nematodes, fruit flies, frogs and mice.
