President Luiz Inácio Lula da Silva pledged to end deforestation by 2030 when he took office a year ago.
Preliminary data from national space agency Inpe showed 5,153 sq km of the Amazon were cleared in 2023, down from 10,278 sq km in 2022. Rainforest destruction had surged to a 12-year high under his predecessor, Jair Bolsonaro.
A new law in Maryland requires Medicaid to cover “medically necessary” gender-affirming care for residents — including care well beyond hormones or surgery. The law went into effect on January 1. It requires coverage for “gender-affirming treatment in a nondiscriminatory manner.” Gender-affirming care is considered safe and essential to the well-being of trans people by the American Academy of Pediatrics, the American Medical Association, the American Psychological Association, and other major U.S. and world health organizations.
Consumption poverty in the United States has fallen dramatically since 1980, according to a major new study from the University of Notre Dame. Researchers found the poverty rate dropped 27 percentage points when measured by what families actually spend rather than what they report earning. The official income-based measure, by contrast, showed only a 1.5 percentage point decline over the same period. The findings suggest decades of policy investment in Social Security, tax credits, and safety net programs have produced far greater results than conventional statistics indicate.
Researchers at Duke-NUS Medical School in Singapore have developed an intranasal COVID-19 vaccine that enhances the immune system’s response to the virus, providing longer-lasting, greater protection than vaccine injections, even against new and emerging variants. The novel vaccine candidate could mean fewer boosters in future.
Building on a previously announced 2.5GW module supply agreement signed in January 2023, Qcells will supply Microsoft with 12GW of solar modules over an 8-year period.

The $3.7-million project could take several decades because of the severity of the environmental damage done by illegal mining, which has deforested the park and polluted its rivers with mercury. The 485,226-acre national park is an important biological corridor along Colombia’s Pacific coast.
The team from U.S. biotech firm Novelna wrote: “At stage I (the earliest cancer stage) and at the specificity of 99%, our panels were able to identify 93% of cancers among males and 84% of cancers among females.” It believes its cheaper, less invasive multi-cancer screening test could be a ‘gamechanger.’
Paulina Hennig-Kloska, who was appointed climate and environment minister in December 2023, said that the half-year moratorium in forests across the country was the first step to limiting logging. The government promised in its coalition agreement to protect 20% of the country’s forests.
