Vocational rehabilitation helps lift people with disabilities out of poverty

Social Security Disability Insurance (SSDI) benefits do not always keep individuals with disabilities out of poverty. To support these individuals' efforts to lift themselves out of poverty, the Substantial Gainful Activity (SGA) Project was piloted in Kentucky and Minnesota. It showed that individuals who engaged in a vocational rehabilitation services intervention were able to earn increased...

Weighing space dust with radar

It is thought that over 1,000 kilograms of so-called interplanetary dust falls to Earth every day. This dust is essentially an untold number of small faint meteors, discarded remnants of asteroids and comets that pass by the Earth. Two ways to study faint meteors are radar and optical observations, each with advantages and limitations. Astronomers have combined specific observations with both...

Pfizer, BioNTech initial vaccine results impress, but scientists remain cautious

Scientists on Monday said initial trial results for Pfizer Inc and BioNTech's coronavirus vaccine far outpaced their expectations for protection against a completely new disease, but that many questions remain unanswered. The drugmakers said their vaccine was more than 90 percent effective at preventing COVID-19, based on data from the first 94 people in the trial to become infected with the...

English study suggests T cells could be sufficient to protect from COVID-19

High levels of so-called "T cells" that respond to the coronavirus could be sufficient to offer protection against infection, an English study said on Tuesday, adding to the evidence of the crucial role they play in immunity to COVID-19. T cells, a type of white blood cell that makes up part of a healthy immune system, are thought to be essential to protect against infection from the SARS-COV-2...

New insight into a placental gene pathway and its association with vitamin D

Vitamin D status during pregnancy has multifaceted effects on maternal health. Researchers found that vitamin D sufficiency lowered the expression of placental genes related to preeclampsia - a severe, and sometimes fatal, condition. Their findings shed new light on the development of preeclampsia during pregnancy and how it may correlate with maternal vitamin D status.

Why do bats fly into walls?

Bats sometimes collide with large walls even though they detect these walls with their sonar system. Researchers from Tel Aviv University have concluded that these collisions do not result from a sensory limitation but rather from an error in acoustic perception.

Researchers identify new Rickettsia bacteria species in dogs

Researchers have identified a new species of Rickettsia bacteria that may cause significant disease in dogs and humans. This new yet unnamed species, initially identified in three dogs, is part of the spotted-fever group Rickettsia which includes Rickettsia rickettsii, the bacteria that cause Rocky Mountain Spotted Fever (RMSF).

Large, delayed outbreaks of endemic diseases possible following COVID-19 controls

Measures such as mask wearing and social distancing that are key to reducing coronavirus infection have also greatly reduced the incidence of other diseases, such as influenza and respiratory syncytial virus (RSV). But researchers report that current reductions in these common respiratory infections, however, may increase people's susceptibility to these diseases, resulting in large future...

One in five COVID-19 patients develop mental illness within 90 days: study

Many COVID-19 survivors are likely to be at greater risk of developing mental illness, psychiatrists said on Monday, after a large study found 20% of those infected with the coronavirus are diagnosed with a psychiatric disorder within 90 days. Anxiety, depression and insomnia were most common among recovered COVID-19 patients in the study who developed mental health problems, and the researchers...

Scientists watch as China remote glaciers melt at 'shocking' pace

Glaciers in China's bleak Qilian mountains are disappearing at a shocking rate as global warming brings unpredictable change and raises the prospect of crippling, long-term water shortages, scientists say. The largest glacier in the 800-km (500-mile) mountain chain on the arid northeastern edge of the Tibetan plateau has retreated about 450 metres since the 1950s, when researchers set up China's...
