Food security: New tool can forecast food insecurity up to 30 days in advance

2023-03-16
(Press-News.org) A new tool that can be used to forecast the prevalence of individuals within a country that may have insufficient access to food — known as food insecurity — up to 30 days into the future is presented in a study published in Scientific Reports. The authors suggest that the tool could aid decision makers in countries at risk of food insecurity and help facilitate more timely responses.

Elisa Omodei and colleagues developed the tool using food consumption data from Burkina Faso, Cameroon, Mali, Nigeria, Syria and Yemen — all countries that have recently experienced acute food insecurity — between 2018 and 2022. The authors enhanced their tool with data on conflict-related fatalities, food prices, extreme weather events and the occurrence of Ramadan — as food consumption patterns within much of each country are altered during this month of the Islamic calendar — throughout this period. They then used their tool to estimate the prevalence of households at risk of insufficient access to food between October 2021 and February 2022.

The authors found that their tool was able to forecast the prevalence of food insecurity within Yemen and Syria with 99% accuracy one day into the future and with 72% and 47% accuracy, respectively, 30 days into the future. However, they found that for the remaining four countries, which had less available food consumption data than Syria and Yemen, the tool’s predictions were not as accurate. This highlights that the tool's forecasts are more accurate when using food consumption data collected at regular intervals over long periods of time and across a broad range of geographic areas.

The authors suggest that their tool could complement existing techniques for modelling food insecurity by providing rapidly available forecasts using real-time data. Their tool’s predictions could be further improved by incorporating mobile phone data or automated text mining of news, they add.

Study of immune ‘neighborhoods’ highlights macrophages as key players in invasive breast cancers
2023-03-16
Most immunotherapies, which aim to boost T cell activity, work poorly in treating estrogen receptor-positive (ER+) breast cancer. Targeting a different type of immune cell called macrophages could be a more effective approach, suggests a comprehensive new analysis of invasive ER+ breast cancers led by University of Pittsburgh School of Medicine scientists. Published today in Nature Cancer, the study found that macrophages were the dominant immune cell infiltrating ER+ invasive lobular carcinoma (ILC) and invasive ductal carcinoma ...

Genetic causes of three previously unexplained rare diseases identified

Genetic causes of three previously unexplained rare diseases identified
2023-03-16
New York, NY (March 16, 2023) – Using a new computational approach they developed to analyze large genetic datasets from rare disease cohorts, researchers at the Icahn School of Medicine at Mount Sinai and colleagues have discovered previously unknown genetic causes of three rare conditions: primary lymphedema (characterized by tissue swelling), thoracic aortic aneurysm disease, and congenital deafness. The work was done in collaboration with colleagues at the University of Bristol, UK; KU Leuven, Belgium; the University of Tokyo; the University of Maryland; Imperial College London, and others from around the world. An enhanced understanding of the functions ...

NYU Abu Dhabi researchers discover a new approach to harvesting aerial humidity with organic crystals
2023-03-16
Fast facts: The global shortage of fresh water currently affects hundreds of millions of people around the world, and it is estimated that by 2025, 1.8 billion people will experience severe water scarcity and hunger due to loss of fertile farming lands caused by droughts. The discovery of alternative water-harvesting technologies holds the potential to alleviate the foreseeable socioeconomic impacts of severe water scarcity. Abu Dhabi, UAE, March 16 2023: Researchers of the Smart Materials Lab (SML) and the Center for Smart Engineering Materials (CSEM) at NYU Abu Dhabi (NYUAD) have reported a novel method of harvesting water from ...

Dual immunotherapy plus chemotherapy before surgery improves patient outcomes in operable lung cancer

Dual immunotherapy plus chemotherapy before surgery improves patient outcomes in operable lung cancer
2023-03-16
HOUSTON ― In a Phase II trial led by researchers from The University of Texas MD Anderson Cancer Center, adding ipilimumab to a neoadjuvant, or pre-surgical, combination of nivolumab plus platinum-based chemotherapy, resulted in a major pathologic response (MPR) in half of all treated patients with early-stage, resectable non-small cell lung cancer (NSCLC). New findings from the NEOSTAR trial, published today in Nature Medicine, provide further support for neoadjuvant immunotherapy-based treatment as an approach to reduce viable tumor at surgery and to improve outcomes in NSCLC. The combination also was associated with an increase in immune cell infiltration and a favorable gut microbiome ...

How fishermen benefit from reversing evolution of cod

How fishermen benefit from reversing evolution of cod
2023-03-16
Leipzig. Intense fishing and overexploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. The new study by researchers from the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University and the Institute of Marine Research in Tromsø, which was published in Nature Sustainability, shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity. The impact of global fisheries on marine ecosystems ...

A research team from the University of Cologne (Germany) and the University of St Andrews (Scotland) has shown in a new study how a fundamental physical concept can be used to boost the colour brilliance of smartphone, computer or TV screens without cutbacks in energy efficiency. The results have been published in Nature Photonics. Organic light-emitting diodes (OLEDs) have conquered the market for displays in recent years – from high-resolution smartphone to wall-sized television screens. However, industry and science face several challenges in creating the next generation of devices ...

Hot topic – how heat flow affects the Earth’s magnetic field

2023-03-16
Hot topic – how heat flow affects the Earth’s magnetic field  Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth’s magnetic field.  The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth’s core, where temperatures exceed 5,000-degress C.  New research from geophysicists at the University of Leeds suggests that ...

Case report of first mixed race woman possibly cured of HIV published in Cell

2023-03-16
A new method to cure HIV—by transplanting HIV-resistant stem cells from umbilical cord blood—has yielded long-term successful results, say scientists. The approach was successfully used to treat the “New York patient,” a middle-aged woman with leukemia and HIV who self-identifies as mixed race, who has been without HIV since 2017. Using stem cells from cord blood rather than from compatible adult donors, as has been done previously, increases the potential to cure HIV via stem cell transplantation ...

Genomic analysis shows the Amazon’s Ashaninka people are made up of two subgroups with distinct histories

Genomic analysis shows the Amazon’s Ashaninka people are made up of two subgroups with distinct histories
2023-03-16
The Ashaninka are the most numerous Indigenous people living in the rainforests of Peru and Brazil where they inhabit a crucial area between the Andes and sources of the Amazon River. And yet, despite the size of the population and their importance in the past and present, their genetic history has remained understudied. Now a team of researchers reporting in the journal Current Biology on March 16 has analyzed the genomes of more than 50 individuals to clarify the group’s interactions with nearby South American regions, including Central America and the Caribbean. ...

Indigenous Ashaninka DNA helps geneticists write new chapters of pre-colonial history in South America

2023-03-16
Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.  The dramatic impact of European colonisation during the second half of the last millennium has strongly influenced the genetic history of the Americas, making the reconstruction ...
