Dialog / Old galaxies in a young universe?
The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at high-redshift. The redshift ...
Phys.org / China's emissions policies are helping climate change but also creating a new problem
China's sweeping efforts to clean up its air have delivered one of the biggest public health success stories of recent decades. Since the Air Pollution Prevention and Control Action Plan was launched in 2013, coal-fired power ...
Medical Xpress / How universal, free prescription drug coverage affects older adults' finances and behaviors
In 2016, Poland introduced a nationwide policy eliminating all out-of-pocket costs for prescription drugs prescribed by health care professionals to individuals aged 75 and older. A study published in Health Economics finds ...
Medical Xpress / Harnessing antiviral memory to fight tumors: Redirected antibodies show promise
Because many different types of cancer cells overexpress programmed death-ligand 1 (PD-L1), this cell surface protein is a major target of cancer immunotherapy. Unfortunately, drugs that target it do not trigger especially ...
Medical Xpress / How certain factors affect life expectancy in people with spina bifida
Studies have reported on survival probabilities of people born with open spina bifida, a condition where the spinal cord and nerves are exposed through an opening in the back. Research published in Developmental Medicine ...
Phys.org / Trump EPA set to repeal scientific finding that serves as basis for US climate change policy
The Trump administration on Thursday will revoke a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change, the White House announced.
Phys.org / Football-sized fossil creature may have been one of the first land animals to eat plants
Life on Earth started in the oceans. Sometime around 475 million years ago, plants began making their way from the water onto the land, and it took another 100 million years for the first animals with backbones to join them. ...
Phys.org / Current flows without heat loss in newly engineered fractional quantum material
A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without losing energy to heat. Described in Nature Physics, the work, led by Xiaodong Xu at the University of ...
Phys.org / Fossil discovery suggests giant pythons once roamed Taiwan
Pythons are a common sight across much of Asia, especially in the tropical jungles and wetlands of countries like Vietnam, Thailand and Indonesia. But one curious exception has been the main island of Taiwan, where there ...
Phys.org / Experiment relies on pulsars to probe dark matter waves
Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...
Phys.org / Bacterial hitchhikers can give their hosts super strength
A Dartmouth study finds that molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The findings introduce a previously unknown ...
Phys.org / Machine learning reveals hidden landscape of robust information storage
In a new study published in Physical Review Letters, researchers used machine learning to discover multiple new classes of two-dimensional memories, systems that can reliably store information despite constant environmental ...
