Giving robots a faster grasp

Researchers at MIT have created an algorithm that significantly speeds up the planning process required for robots to adjust their grasp on objects. The new approach uses motion cones to efficiently calculate feasible pushes and reposition objects in less than a second, compared to traditional algorithms that take over 500 seconds.

The Lancet Haematology: First global estimates suggest around 100 million more blood units are needed in countries with low supplies each year

The global demand for blood transfusions exceeds the available supply by 30 million units annually, with the largest shortages found in lower-income countries. The estimated shortfall varies sharply between countries, with some requiring up to 75 times more blood than their supply can provide.

High-risk patients benefit from undergoing surgery at teaching hospitals

A new study published in Annals of Surgery found that high-risk patients who underwent general or vascular surgery at major teaching hospitals had significantly lower 30-day mortality rates (15.9% vs 18.2%) and reduced costs compared to non-teaching hospitals. Orthopedic surgery patients showed similar outcomes at both types of hospitals.

How do ketogenic diets affect skin inflammation?

A study published in the Journal of Investigative Dermatology found that ketogenic diets heavy in coconut oil and palm oils worsened psoriasiform-like skin inflammation in mice. In contrast, well-balanced ketogenic diets with long-chain triglycerides did not exacerbate skin inflammation.

Communicating uncertainty about climate change

A new Stanford study found that expressing uncertainty about climate change predictions increases public trust in scientists, but acknowledging unknown factors can undermine credibility. When climate scientists include best-case and worst-case scenarios, Americans are more trusting and accepting of their statements.

Deep water sites off the US northeast coast are suitable for offshore blue mussel farms

Researchers at NOAA's Northeast Fisheries Science Center have identified suitable locations off the US northeast coast for offshore blue mussel farms. The study suggests that Long Island, north of Cape Ann in Massachusetts, and off New Hampshire are promising sites due to favorable temperature and food availability conditions.

Biodiversity improves crop production

A study involving over 100 researchers demonstrates that biodiversity enhances pollination and biological pest control, leading to increased crop yields. Higher agricultural biodiversity also reduces the reliance on pesticides, promoting sustainable agriculture.

Fully recyclable packaging materials

Researchers at the University of the Basque Country and Colorado State University have developed a class of biorenewable, biodegradable plastics that promote the circular economy. The new materials have suitable mechanical and barrier properties similar to commercial materials currently used in packaging.
