Study paves the way for new photosensitive materials
Photocatalysts are useful materials, with a myriad of environmental and energy applications, including air purification, water treatment, self-cleaning surfaces, pollution-fighting paints and coatings, hydrogen production and CO2 conversion to sustainable fuels.
Major Everglades restoration project to break ground this year
A key project in the restoration of the Everglades moved forward Thursday with the signing of an agreement between Florida and the federal government to construct a huge reservoir south of Lake Okeechobee.
Ancient Indigenous forest gardens promote a healthy ecosystem, says study
A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests—cared for as "forest gardens"—contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators. The findings are published today in Ecology and Society.
Machine learning model generates realistic seismic waveforms
A new machine-learning model that generates realistic seismic waveforms will reduce manual labor and improve earthquake detection, according to a study published recently in JGR Solid Earth.
Scientists uncover structure of light-driven enzyme with potential biofuel applications
Although many organisms capture and respond to sunlight, enzymes—proteins that catalyze biochemical reactions—are rarely driven by light. Scientists have identified only three types of natural photoenzymes so far. The newest one, discovered in 2017, is fatty acid photodecarboxylase (FAP). Derived from microscopic algae, it uses blue light to catalyze the conversion of fatty acids, found in...
The US is the biggest carbon emitter in history. Where do other nations stand?
It's not just the United States—other major polluters around the world have also been falling behind the climate goals they set for themselves under the Paris agreement.
Climate change, racism and social justice concerns affecting Gen Z's physical and mental health
As Earth Day is celebrated, Generation Z is grappling with the health of the planet and racism and social justice, according to a new survey.
SpaceX aims for 3rd crew launch hour before Friday's sunrise
SpaceX aimed to launch its third crew a little before sunrise Friday, this time using a recycled capsule and rocket.
Expedition hauls tons of plastic out of remote Hawaii atolls
A crew returned from the northernmost islands in the Hawaiian archipelago this week with a boatload of marine plastic and abandoned fishing nets that threaten to entangle endangered Hawaiian monk seals and other animals on the uninhabited beaches stretching more than 1,300 miles north of Honolulu.
Genetic effects of Chernobyl radiation

Researchers utilized genomic tools to investigate potential health effects of exposure to ionizing radiation, a known carcinogen, as a result of the 1986 Chernobyl accident. One study found no evidence that genetic changes associated with radiation exposure are passed to children, while the second study documented the genetic changes in the tumors of people who developed thyroid cancer after being...
Scientists uncover structure of light-driven enzyme with potential biofuel applications

- 21/4/22 21:04
Although many organisms capture and respond to sunlight, enzymes - proteins that catalyze biochemical reactions - are rarely driven by light. A new study captures the full cycle of complex structural changes in an enzyme called FAP as it transforms a fatty acid into alkanes or alkenes.
Immune system, not COVID virus, may pose greatest risk to pregnant women
- ScienceDaily
- 21/4/22 21:04
Scientists investigated whether the COVID-19 virus could be affecting placental tissue of infected expectant mothers. Their analysis found that while evidence of the virus in the placenta is rare, the placenta in infected mothers tended to exhibit a much higher level of immune system activity than those of non-infected pregnant women, they report.
A new method for fighting 'cold' tumors
- ScienceDaily
- 21/4/22 21:04
Researchers address cold tumors in new research. Working with mouse models of head and neck cancers, researchers studied the role of T cells in tumor treatment.
Mars has right ingredients for present-day microbial life beneath its surface, study finds

A mitochondrial peptide called MOCCI has a surprising sidekick, and they work together to regulate inflammation and immunity, researchers reveal.
Experimental drug shows potential against Alzheimer's disease
- ScienceDaily
- 21/4/22 21:04
Researchers have designed an experimental drug that reversed key symptoms of Alzheimer's disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them.
Anti-aging compound improves muscle glucose metabolism in people

In the first clinical trial of nicotinamide mononucleotide (NMN), researchers have found that the compound previously demonstrated to counteract aspects of aging and improve metabolic health in mice also has clinically relevant effects in people.
Researchers trace spinal neuron family tree
- ScienceDaily
- 21/4/22 21:03
Spinal cord nerve cells branching through the body resemble trees with limbs fanning out in every direction. But this image can also be used to tell the story of how these neurons, their jobs becoming more specialized over time, arose through developmental and evolutionary history. Researchers have traced the development of spinal cord neurons using genetic signatures and revealed how different...
Salad or cheeseburger? Your co-workers shape your food choices

Employees' cafeteria purchases -- both healthy and unhealthy foods -- were influenced by their co-workers' food choices, found a large, two-year study of hospital employees. The study made innovative use of cash register data to gain insights into how individuals' social networks shape their health behavior. The research suggests we might structure future efforts aimed at improving population...
Watch TIME’s Exclusive Footage of NASA’s Most Powerful Rocket Ever Under Construction
Rockets are built slowly—slowly and exceedingly carefully—which is in keeping with giant machines on which humans stake their lives and nations stake their prestige. In NASA’s cavernous Vehicle Assembly Building at Cape Canaveral, America’s next great moon rocket—the Space Launch System (SLS)—is being constructed with all that in mind. It is here too that TIME...
