New research shows adult neurogenesis does not persist in the human hippocampus

The generation of new neurons in the human hippocampus strongly decreases from childhood to almost undetectable levels in adults. It can therefore be stated that neurogenesis in the human hippocampus is almost non-existent, as opposed to what has been thought in recent decades. 6th World Conference on Neurology and Neurosurgery will be organized during March 27-28, 2019…

Scientists move quantum optic networks a step closer to reality

Scientists have moved quantum optic networks a step closer to reality. The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more quickly and securely than an electrical network. A team of researchers at the U.S. Department of Energy’s (DOE) Argonne…

A new home for optical solitons

Laser physicists based at the Laboratory for Attosecond Physics run by the Max Planck Institute of Quantum Optics and the Ludwig-Maximilian University have, for the first time, generated dissipative solitons in passive, free-space resonators. Solitons are the most stable of all waves. Under conditions that result in the dispersion of all other waveforms, a soliton…

Ulcers from diabetes? New shoe insole could provide healing on-the-go

Researchers have developed a shoe insole that could help make the healing process more portable for the 15 percent of Americans who develop ulcers as a result of diabetes. Purdue University researchers have developed a shoe insole that could help make the healing process more portable for the 15 percent of Americans who develop ulcers…

No new patients should start treatment with Lartruvo after study shows cancer medicine does not prolong life: EMA

Preliminary results from the ANNOUNCE study show that Lartruvo (olaratumab) in combination with doxorubicin is not more effective at prolonging the lives of patients with soft tissue cancer than doxorubicin alone. 12th International Conference on Pharmaceutical Chemistry during May 20-21, 2019 at Berlin, Germany.  The conference emphasizes the theme “Exploring the Challenges in Pharmaceutical Chemistry & Process of Drug Discovery for the Future”.

All-photonic quantum repeaters could lead to a faster, more secure global quantum internet

Engineering researchers have demonstrated proof-of-principle for a device that could serve as the backbone of a future quantum Internet. University of Toronto Engineering professor Hoi-Kwong Lo and his collaborators have developed a prototype for a key element for all-photonic quantum repeaters, a critical step in long-distance quantum communication. A quantum Internet is the ‘Holy Grail’…

New technology uses lasers to transmit audible messages to specific people

Researchers have demonstrated that a laser can transmit an audible message to a person without any type of receiver equipment. The ability to send highly targeted audio signals over the air could be used to communicate across noisy rooms or warn individuals of a dangerous situation such as an active shooter. In The Optical Society…

Terahertz laser for sensing and imaging outperforms its predecessors

A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once — high constant power, tight beam pattern, and broad electric frequency tuning — and could thus be valuable for a wide range of applications in chemical sensing and imaging. The optimized laser can be used to detect…
