Enough rare earth minerals to fuel green energy shift: study

The Hindu:Science - 27/01/2023
The world is trying to switch from electricity produced by burning fossil fuels to cleaner wind and solar power, but some people have worried that there aren’t enough rare earth minerals to make the green electricity switch

New blood test can detect Alzheimer's 3.5 years before diagnosis

The Hindu:Science - 27/01/2023
Neurogenesis occurs in an important part of the brain called the hippocampus that is involved in learning and memory.

Large mammals shaped the evolution of humans: Here's why it happened in Africa

The Hindu:Science - 27/01/2023
It’s not generally recognised how unique features of Africa’s ecology were responsible for the crucial evolutionary transitions.

Poor literacy linked to worse mental health problems: Study

The Hindu:Science - 27/01/2023
Little or no literacy disproportionately affects women, the researchers found in the first study that looks at the association between mental health and literacy on a global scale

Worst impacts of sea level rise will hit earlier than thought: Study

The Hindu:Science - 27/01/2023
Analyses of data showed two metres of sea-level rise would cover up to 2.4 times the land area as observed by radar-based elevation models.

Phew! Truck-sized asteroid misses Earth

The Hindu:Science - 27/01/2023
Asteroid 2023 BU whizzed past without incident and back out into the blackness of space.

The third human landing on the moon

The Hindu:Science - 27/01/2023
On February 5, 1971, Apollo 14 made a successful landing on the lunar surface, thereby becoming the third human landing on the moon after Apollo 11 and Apollo 12. A.S.Ganesh gives an overview of the Apollo 14 mission and some lessons we learnt from it…

Events serve as 'stepping stones' en route to retrieved memories

Science Daily - 27/01/2023
Lost your keys again? You might retrace your steps by scanning your memory using certain event boundaries -- when one event ends (say, walking in the door with your keys) and another begins (checking your phone, turning on the TV).

LiDAR technology could improve safety features in vehicles

Science Daily - 27/01/2023
Dr. Scott Budge and his student Chaz Cornwall published a paper in Optical Engineering where they argue the benefits of LiDAR technology in commercial vehicles.

When should data scientists try a new technique?

Science Daily - 27/01/2023
Researchers created a new measure, called the c-value, that helps statisticians and data scientists choose between estimation techniques based on the chance that a new method is more accurate for a specific dataset and application.

Most U.S. children use potentially toxic makeup products, often during play

Science Daily - 27/01/2023
Scientists found that most children in the United States use makeup and body products that may contain carcinogens and other toxic chemicals.

Quantum physicists make major nanoscopic advance

Science Daily - 27/01/2023
In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.

Secret recipe for limonoids opens door for bee-friendly crop protection

Science Daily - 27/01/2023
Innovative research has uncovered the secret of how plants make limonoids, a family of valuable organic chemicals which include bee-friendly insecticides and have potential as anti-cancer drugs.

Solar System formed from 'poorly mixed cake batter,' isotope research shows

Science Daily - 27/01/2023
Earth's potassium arrived by meteoritic delivery service finds new research led by Earth and planetary scientists. Their work shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our Solar System and determined the composition of its planets.

India’s first mission to study the Sun will be launched by June-July: ISRO chairman 

The Hindu:Science - 27/01/2023
The Aditya-L1 mission will be launched by ISRO to the L1 orbit (which is the first Lagrangian point of the Sun-Earth system). L1 orbit allows Aditya-L1 to look at the Sun continuously.

Researchers demo new type of carbon nanotube yarn that harvests mechanical energy

Science Daily - 26/01/2023
Nanotechnology researchers have made novel carbon nanotube yarns that convert mechanical movement into electricity more effectively than other material-based energy harvesters.

New AI tool makes speedy gene-editing possible

Science Daily - 26/01/2023
An artificial intelligence program may enable the first simple production of customizable proteins called zinc fingers to treat diseases by turning genes on and off. The researchers who designed the tool say it promises to accelerate the development of gene therapies on a large scale.

Targeting cancer with a multidrug nanoparticle

Science Daily - 26/01/2023
Chemists designed a bottlebrush-shaped nanoparticle that can be loaded with multiple drugs, in ratios that can be easily controlled. Using these particles, the researchers calculated and delivered the optimal ratio of three cancer drugs used to treat multiple myeloma.

Farming more seaweed to be food, feed and fuel

Science Daily - 26/01/2023
A new study has shown that expanding global seaweed farming could go a long way to addressing the planet's food security, biodiversity loss and climate change challenges.
