Blood clots and lung injuries found in patients who have died of COVID-19

A new post-mortem study of patients who have died from COVID-19 found severe damage to the lungs and signs of blood clotting in major organs.

Dilated blood vessels in the lung may explain low oxygen levels in severe cases of COVID-19

A new pilot study suggests that COVID-19 is causing significant dilation of the blood vessels of the lung, specifically the capillaries.

Team creates better tool to aid COVID-19 diagnosis

A radiologist and an evolutionary anatomist have teamed up to show the same techniques used for research on reptile and bird lungs can be used to help confirm the diagnosis of COVID-19 in patients. Their paper demonstrates that 3D models are a strikingly clearer…

Oxygen therapy harms lung microbiome in mice

A new mouse study hints that oxygen therapy may have unintended consequences via an unexpected source — the microbiome.

Heavier smoking linked to skyrocketing health risks

Each cigarette smoked a day by heavier smokers increases the risk of contracting some diseases by more than 30 per cent, according to a new study.

COVID-19: The virus and the vasculature

In severe cases of COVID-19, the infection can lead to obstruction of the blood vessels in the lung, heart and kidneys. Researchers have now shown that activated immune cells and blood platelets play a major role in these pathologies.

COVID-19 vaccine shows promise in mouse studies

A new study has found that the investigational vaccine known as mRNA-1273 protected mice from infection with SARS-CoV-2, the virus that causes COVID-19.

Assembly within the tumor center

Number of macrophages in tumor tissue enables prognosis of lung tumor progression.

Blood-thinner with no bleeding side-effects is here

Scientists have developed a synthetic blood-thinner that, unlike all others, doesn’t cause bleeding side-effects. The highly potent, highly selective, and highly stable molecule can suppress thrombosis while letting blood clot normally following injury.

How airway cells work together in regeneration and aging

Researchers have identified the process by which stem cells in the airways of the lungs switch between two distinct phases — creating more of themselves and producing mature airway cells — to regenerate lung tissue after an injury.
